21 General Process of CDR ProducingIn each call process the CSOFTX3000 collects information about the call to generate theoriginal CDRs for final charging and settlement by network operators or service providersThe process to produce CDRs is as follows1 The CSOFTX3000 collects the call data to generate the original CDRs and stores them inthe bill pool2 The CSOFTX3000 sends the original CDRs in real time to the charging gateway (iGWB)through the local area network (LAN)3 The iGWB produces the final CDRs and sends them to the billing center4 The public land mobile network (PLMN) operator produces detailed service bills for theend users based on the final CDRsThe entire process of producing a CDR comprises the collecting of information producing theCDR storing the CDR and transferring the CDR

22 Call Data CollectionWhen a mobile subscriber originates or answers a call the CSOFTX3000 records all theinformation about the callData Collection for Mobile Originated Calls

When the call request is sent to the CSOFTX3000 the CSOFTX3000 records all theinformation related to the calling party such as the calling number international mobilestation identity (IMSI) and location (home MSC BSC and cell)The CSOFTX3000 also records all the information related to the called party after analyzingthe called number If it is an outgoing call the CSOFTX3000 records the data related to thetrunkData Collection for Mobile Terminated CallsIf the MS answers a call the visited MSC (VMSC) records all the data related to the calledparty10486981048698If both the calling and called parties are served by the same VMSC the VMSC recordsall the data related to the calling and the called party for producing a mobile originatedcall (MOC) CDR and a mobile terminated call (MTC) CDR10486981048698If the call request comes from another MSC through the trunk then the VMSC throughwhich the called party is served records the data about the call for producing an MTCCDRHUAWEI CSOFTX3000CDR Description 2 CDR ProducingIssue 03 (2007-11-30) Huawei Technologies Proprietary 2-3

23 Producing of CDRWhen a call completes or the duration of the call reaches the threshold for a long-durationcall or the call type changes the CSOFTX3000 records the following data10486981048698Call start date and time10486981048698Duration10486981048698CDR type (such as MOC or MTC)10486981048698Call termination reason (such as normal release or conversation timeout)The CSOFTX3000 also collects data related to the CDRs such as serial number of the CDRsserial number of the initial CDR record types (such as First Bill Last Bill or IntermediateBill) The data is used for CDR managementAfter collecting all the CDR data the CDRs are produced based on the collected data and arestored in the bill poolThe CDRs for intelligent users and common users are produced differently

231 Producing of Ordinary Service CDRThe overall process of producing CDRs for an ordinary service user is as follows1 In the call process the call processing module collects the billing information such asuser number call start time call duration and call attributes2 When the call is terminated the module records the call end time and generates theoriginal CDRs for this call3 The module then sends the original CDRs to the iGWB4 The iGWB processes the CDRs and produces the final CDR5 The billing center collects the final CDR from the iGWB and sorts the CDR according tothe charging policy of specific operators The billing center then generates the telephonebill for the end user2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-4 Huawei Technologies Proprietary Issue 03 (2007-11-30)

BillingCenterSettlementCenterSSPSCPSMPSettlement resultand remote CDRBilling infoCDR managementCall start Call endCDRSMP service management point SCP service control point SSP service switching pointWhen processing an intelligent call the SSP (Service Switching Point) accomplishes theconnection and play of prompt tones according to instructions given by the SCP (ServiceControl Point) The SCP determines whether to conduct billing on a specific call according tothe relevant business policiesThe overall process of producing CDRs for an intelligent service user is as follows1 The SSP reports the O_ANSWERT_ANSWER event when a call is triggered The SCPthen starts the billing process2 The SSP reports the O_DISCONNECTT_DISCONNECT event when the call isterminated3 According to the information contained in the events reported by the SSP the SCPmonitors the recording of the billing information and generates the original CDR4 At the same time the SSP generates a CDR that carries an intelligent service tag for theSCP to double-check the billing informationIn certain scenarios the following processes are involved1 The SCP transfers the CDR to the SMP (Service Management Point)2 The SMP then forwards the CDR to the settlement center3 The settlement center allocates the sum sorts the CDRs and then sends the CDRs withthe allocated sums to different billing centersIn the entire process of an intelligent call the SCP may conduct real-time charging and deductthe sum from the user account directly or may conduct the charging after the call isterminatedHUAWEI CSOFTX3000CDR Description 2 CDR ProducingIssue 03 (2007-11-30) Huawei Technologies Proprietary 2-5Control Mechanism Involved with Intelligent Service BillingBilling for intelligent services includes local intelligent calls and toll intelligent calls Thebilling policy is subject to the service administration entity and the service subscriber TheSCP is the entity that implements the billing while the SSP is the entity that reports the billinginformation The settlement center is responsible for allocating the sum to different billingpartiesThe two intelligent call triggers installed on the SSP are as follows10486981048698O_ANSWERT_ANSWER trigger When an intelligent call starts the SSP reports to theSCP an event that contains the start time billing ID and billing user ID10486981048698O_DISCONNECTT_DISCONNECT trigger When an intelligent call terminates theSSP reports to the SCP an event that contains the termination time billing ID and billinguser ID of the callThe SSP reports various call events to the SCP according to the setting of the triggers TheSCP then conducts billing according to the reported events and forwards the CDRs to the SMPif an allocation is required The SMP forwards the allocated sum to the settlement center forfinal chargingGeneral Principle of Producing Intelligent CDRs

In an intelligent call the SSP need not produce the CDRs because the SSP providesinformation only about the call for the SCP The CSOFTX3000 acting as an SSP produces anordinary service CDR for an intelligent call to allow a cross-check mechanism for theoperators It also adds an intelligent service tag to the CDR for the billing center

24 CDR StorageThe WCCUWCSU in the CSOFTX3000 stores the CDRs in the first-in-first-out (FIFO)modeThe CSOFTX3000 stores the CDRs in the bill pool and sends them to the iGWB in real timeThe space of a CDR in the bill pool is not released until the CDR reaches the iGWB

25 CDR Processing on iGWBThe information collected on the CSOFTX3000 is stored in the CDR pool and sent to theiGWB for processingThe iGWB receives the original CDR from the CSOFTX3000 over its self-defined protocolThe iGWB relies on a dual-machine hardware backup to guarantee correct billing informationwithout losing or repeating a CDRSorted CDRs are stored in different directories to be collected by the billing center Afterprocessing the original CDR the iGWB produces the final CDR The processing flow isshown in Figure 2-10HUAWEI CSOFTX3000CDR Description 2 CDR ProducingIssue 03 (2007-11-30) Huawei Technologies Proprietary 2-13Figure 2-10 CDR processing flowSortingFormatConversionOriginalCDRFinalCDRCDR Sorting

CDR sorting classifies CDRs of different billing conditions into different groups to processand save them to different physical paths You can define the criteria according to the datafields in the CDR Here the data fields can act as the criteria for the sortingCDR Format ConversionThe format of a specific CDR is related to the version of the equipment In the appendix ofversion release notes the CDR format and samples are provided for your referenceYou can ask Huawei support engineers to provide correct documents about related equipment versions

26 CDR SendingTo increase the reliability of the bill pool and to send the CDRs to the iGWB theCSOFTX3000 uses the sliding window transfer protocol This protocol ensures a timelyaccurate and continuous transfer In this case no CDR is lost or sent repeatedlyThe process to send a CDR is as follows1 The iGWB and bill pool negotiates the start serial number for the CDRs to be sentthrough handshake messages2 After receiving the CDRs the iGWB returns a response to the bill pool indicating that ithas received the negotiated CDRs3 If a correct reply is not received after sending a batch of CDRs the bill pool does notsend the next batch but resends the first CDR of the same batch4 If the correct reply is received the bill pool sends the CDRs of the next batch2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-14 Huawei Technologies Proprietary Issue 03 (2007-11-30)

27 CDR CheckingTo ensure that the CDRs are correct the CSOFTX3000 carries out a cyclic redundancy check(CRC) when producing sending and receiving the CDRs10486981048698Before storing the CDRs in the bill pool the CSOFTX3000 carries out a CRC check andstores the checksum in the bill pool10486981048698After receiving the CDRs the iGWB performs a CRC When the check fails thegateway assumes that the bills have changed during transfer When converting theoriginal CDRs to the final CDRs the gateway stores the final CDRs to another directoryHere the final CDRs result from the original CDRs that fail in the CRC Themaintenance staff then handles the final CDRsHUAWEI CSOFTX3000CDR Description 3 CDR Types and FormatsIssue 03 (2007-11-30) Huawei Technologies Proprietary 3-1

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

231 Producing of Ordinary Service CDRThe overall process of producing CDRs for an ordinary service user is as follows1 In the call process the call processing module collects the billing information such asuser number call start time call duration and call attributes2 When the call is terminated the module records the call end time and generates theoriginal CDRs for this call3 The module then sends the original CDRs to the iGWB4 The iGWB processes the CDRs and produces the final CDR5 The billing center collects the final CDR from the iGWB and sorts the CDR according tothe charging policy of specific operators The billing center then generates the telephonebill for the end user2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-4 Huawei Technologies Proprietary Issue 03 (2007-11-30)

In an intelligent call the SSP need not produce the CDRs because the SSP providesinformation only about the call for the SCP The CSOFTX3000 acting as an SSP produces anordinary service CDR for an intelligent call to allow a cross-check mechanism for theoperators It also adds an intelligent service tag to the CDR for the billing center

24 CDR StorageThe WCCUWCSU in the CSOFTX3000 stores the CDRs in the first-in-first-out (FIFO)modeThe CSOFTX3000 stores the CDRs in the bill pool and sends them to the iGWB in real timeThe space of a CDR in the bill pool is not released until the CDR reaches the iGWB

26 CDR SendingTo increase the reliability of the bill pool and to send the CDRs to the iGWB theCSOFTX3000 uses the sliding window transfer protocol This protocol ensures a timelyaccurate and continuous transfer In this case no CDR is lost or sent repeatedlyThe process to send a CDR is as follows1 The iGWB and bill pool negotiates the start serial number for the CDRs to be sentthrough handshake messages2 After receiving the CDRs the iGWB returns a response to the bill pool indicating that ithas received the negotiated CDRs3 If a correct reply is not received after sending a batch of CDRs the bill pool does notsend the next batch but resends the first CDR of the same batch4 If the correct reply is received the bill pool sends the CDRs of the next batch2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-14 Huawei Technologies Proprietary Issue 03 (2007-11-30)

27 CDR CheckingTo ensure that the CDRs are correct the CSOFTX3000 carries out a cyclic redundancy check(CRC) when producing sending and receiving the CDRs10486981048698Before storing the CDRs in the bill pool the CSOFTX3000 carries out a CRC check andstores the checksum in the bill pool10486981048698After receiving the CDRs the iGWB performs a CRC When the check fails thegateway assumes that the bills have changed during transfer When converting theoriginal CDRs to the final CDRs the gateway stores the final CDRs to another directoryHere the final CDRs result from the original CDRs that fail in the CRC Themaintenance staff then handles the final CDRsHUAWEI CSOFTX3000CDR Description 3 CDR Types and FormatsIssue 03 (2007-11-30) Huawei Technologies Proprietary 3-1

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

21 General Process of CDR ProducingIn each call process the CSOFTX3000 collects information about the call to generate theoriginal CDRs for final charging and settlement by network operators or service providersThe process to produce CDRs is as follows1 The CSOFTX3000 collects the call data to generate the original CDRs and stores them inthe bill pool2 The CSOFTX3000 sends the original CDRs in real time to the charging gateway (iGWB)through the local area network (LAN)3 The iGWB produces the final CDRs and sends them to the billing center4 The public land mobile network (PLMN) operator produces detailed service bills for theend users based on the final CDRsThe entire process of producing a CDR comprises the collecting of information producing theCDR storing the CDR and transferring the CDR

22 Call Data CollectionWhen a mobile subscriber originates or answers a call the CSOFTX3000 records all theinformation about the callData Collection for Mobile Originated Calls

When the call request is sent to the CSOFTX3000 the CSOFTX3000 records all theinformation related to the calling party such as the calling number international mobilestation identity (IMSI) and location (home MSC BSC and cell)The CSOFTX3000 also records all the information related to the called party after analyzingthe called number If it is an outgoing call the CSOFTX3000 records the data related to thetrunkData Collection for Mobile Terminated CallsIf the MS answers a call the visited MSC (VMSC) records all the data related to the calledparty10486981048698If both the calling and called parties are served by the same VMSC the VMSC recordsall the data related to the calling and the called party for producing a mobile originatedcall (MOC) CDR and a mobile terminated call (MTC) CDR10486981048698If the call request comes from another MSC through the trunk then the VMSC throughwhich the called party is served records the data about the call for producing an MTCCDRHUAWEI CSOFTX3000CDR Description 2 CDR ProducingIssue 03 (2007-11-30) Huawei Technologies Proprietary 2-3

23 Producing of CDRWhen a call completes or the duration of the call reaches the threshold for a long-durationcall or the call type changes the CSOFTX3000 records the following data10486981048698Call start date and time10486981048698Duration10486981048698CDR type (such as MOC or MTC)10486981048698Call termination reason (such as normal release or conversation timeout)The CSOFTX3000 also collects data related to the CDRs such as serial number of the CDRsserial number of the initial CDR record types (such as First Bill Last Bill or IntermediateBill) The data is used for CDR managementAfter collecting all the CDR data the CDRs are produced based on the collected data and arestored in the bill poolThe CDRs for intelligent users and common users are produced differently

231 Producing of Ordinary Service CDRThe overall process of producing CDRs for an ordinary service user is as follows1 In the call process the call processing module collects the billing information such asuser number call start time call duration and call attributes2 When the call is terminated the module records the call end time and generates theoriginal CDRs for this call3 The module then sends the original CDRs to the iGWB4 The iGWB processes the CDRs and produces the final CDR5 The billing center collects the final CDR from the iGWB and sorts the CDR according tothe charging policy of specific operators The billing center then generates the telephonebill for the end user2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-4 Huawei Technologies Proprietary Issue 03 (2007-11-30)

In an intelligent call the SSP need not produce the CDRs because the SSP providesinformation only about the call for the SCP The CSOFTX3000 acting as an SSP produces anordinary service CDR for an intelligent call to allow a cross-check mechanism for theoperators It also adds an intelligent service tag to the CDR for the billing center

24 CDR StorageThe WCCUWCSU in the CSOFTX3000 stores the CDRs in the first-in-first-out (FIFO)modeThe CSOFTX3000 stores the CDRs in the bill pool and sends them to the iGWB in real timeThe space of a CDR in the bill pool is not released until the CDR reaches the iGWB

CDR sorting classifies CDRs of different billing conditions into different groups to processand save them to different physical paths You can define the criteria according to the datafields in the CDR Here the data fields can act as the criteria for the sortingCDR Format ConversionThe format of a specific CDR is related to the version of the equipment In the appendix ofversion release notes the CDR format and samples are provided for your referenceYou can ask Huawei support engineers to provide correct documents about related equipment versions

26 CDR SendingTo increase the reliability of the bill pool and to send the CDRs to the iGWB theCSOFTX3000 uses the sliding window transfer protocol This protocol ensures a timelyaccurate and continuous transfer In this case no CDR is lost or sent repeatedlyThe process to send a CDR is as follows1 The iGWB and bill pool negotiates the start serial number for the CDRs to be sentthrough handshake messages2 After receiving the CDRs the iGWB returns a response to the bill pool indicating that ithas received the negotiated CDRs3 If a correct reply is not received after sending a batch of CDRs the bill pool does notsend the next batch but resends the first CDR of the same batch4 If the correct reply is received the bill pool sends the CDRs of the next batch2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-14 Huawei Technologies Proprietary Issue 03 (2007-11-30)

311 CDR Classification by StorageOriginal CDROriginal CDR is the billing data unit generated and stored on the CSOFTX3000WCCUWCSU The CSOFTX3000 generates and sends the original CDRs to the iGWB inreal-time through an Ethernet connectionFinal CDRUpon receiving the original CDR from the CSOFTX3000 WCCUWCSU the iGWB storesthe CDRs on the hard disk sorts the CDRs and then converts the CDR data format Thesorted and converted CDRs are stored on the hard disk according to certain rules and arecalled the final CDR The services providers charge the end users based on the final CDRs

312 CDR Classification by Call ProcessCDRs of the CSOFTX3000 are classified into two types according to the producing processIntermediate CDRIf the duration of a call exceeds the threshold of the long-duration call timer of theCSOFTX3000 a CDR is produced in each cycle of the timer This CDR is called theintermediate CDRTerminative CDRTerminative CDR is the original CDR which is generated when a call is terminated and theresource is released by the systemA terminative CDR is produced if the duration of a call is shorter than the timer This CDRrecords the information of the entire call process In case the duration of a call is longer thanthe timer an intermediate CDR and a terminative CDR are produced The terminative CDRhowever records only the information collected within the time of the last long-duration calltimerEach intermediate CDR of the CSOFTX3000 records only the information collected in thetime of the long-duration call timer that corresponds to the CDR At the billing center all theintermediate CDRs and the terminative CDR are added up to calculate the actual sum whichis charged for the callHUAWEI CSOFTX3000CDR Description 3 CDR Types and FormatsIssue 03 (2007-11-30) Huawei Technologies Proprietary 3-3

313 CDR Classification By ScenarioMOC CDR and MTC CDRWhen an MS originates a call and the called party answers an MOC CDR is produced duringthe call or when the call is terminatedWhen an MS terminates a call an MTC CDR is produced during the call or when the callterminatesRoam CDRThe roam CDR is generated at the GMSC for a call from a public switched telephone network(PSTN) or another mobile network to the serving network The roam CDR is a chargingreference for the PSTN or another mobile network The roam CDR is also a reference forsettling trunk occupation expenses between the serving network and the PSTN or between

two mobile networksYou can decide whether to generate the roam CDR through data configurationFor details see 51 Control on the Producing of CDRsTransit CDRThe transit CDR is produced on the CSOFTX3000 when10486981048698A call is routed to the CSOFTX3000 but the call is neither originated from norterminated at the CSOFTX3000 and10486981048698Both the outgoing and the incoming directions of the call are the CSOFTX3000Transit CDRs are not produced for calls forwarded by the local CSOFTX3000You can decide whether to generate the transit CDR by configuring dataGateway_Outgoing CDRA gateway outgoing CDR is generated when10486981048698A call reaches another mobile network from a gateway office10486981048698A call reaches the PSTN from a gateway officeThe gateway outgoing CDR is a reference for billing in the following cases10486981048698Settlement of trunk occupation between the serving PLMN and the PSTN10486981048698Settlement of trunk occupation between two mobile networksYou can decide whether to generate the gateway outgoing CDR by configuring dataCFW CDRA call forwarding (CFW) CDR is produced when the call forwarding service is triggered Thecall forwarding service enables a call to be forwarded to another specified numberA CFW CDR covers three parties10486981048698A calling party3 CDR Types and FormatsHUAWEI CSOFTX3000CDR Description3-4 Huawei Technologies Proprietary Issue 03 (2007-11-30)10486981048698An original called party (the subscriber who forwards the call)10486981048698A final called party (the subscriber who finally answers the call)The CFW CDR charges only the original called party In the CFW CDR10486981048698The calling party is the subscriber who forwards the call10486981048698The called party is the subscriber who finally answers the call10486981048698The third-party is the calling party10486981048698The IMSI and mobile directory number (MDN) contain the attributes of the originalcalled partyThe CFW CDR also displays the call forwarding type which includes the following10486981048698Call forwardingndashunconditional (CFU)10486981048698Call forwardingndashbusy (CFB)10486981048698Call forwardingndashno answer (CFNA)10486981048698Call forwardingndashdefault (CFD)MO_SMS CDR and MT_SMS CDRAn MO_SMS CDR is produced for the subscriber who sends the message and an MT_SMSCDR is produced for the subscriber who receives the message An SMS CDR does notdistinguish IN subscribers from ordinary subscribersIn the SMS mode the handset transmits characters through the signaling channel or voicechannel Different from the ordinary CDR the MO_SMS CDR and MT_SMS CDR containthe following fields10486981048698Number of bytesThis field indicates the number of bytes in the UserPart within the short message that is thelength of the content after it is decoded10486981048698Address of the message centerThis field indicates the message center through which the short message travels In the CDMA

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

21 General Process of CDR ProducingIn each call process the CSOFTX3000 collects information about the call to generate theoriginal CDRs for final charging and settlement by network operators or service providersThe process to produce CDRs is as follows1 The CSOFTX3000 collects the call data to generate the original CDRs and stores them inthe bill pool2 The CSOFTX3000 sends the original CDRs in real time to the charging gateway (iGWB)through the local area network (LAN)3 The iGWB produces the final CDRs and sends them to the billing center4 The public land mobile network (PLMN) operator produces detailed service bills for theend users based on the final CDRsThe entire process of producing a CDR comprises the collecting of information producing theCDR storing the CDR and transferring the CDR

22 Call Data CollectionWhen a mobile subscriber originates or answers a call the CSOFTX3000 records all theinformation about the callData Collection for Mobile Originated Calls

When the call request is sent to the CSOFTX3000 the CSOFTX3000 records all theinformation related to the calling party such as the calling number international mobilestation identity (IMSI) and location (home MSC BSC and cell)The CSOFTX3000 also records all the information related to the called party after analyzingthe called number If it is an outgoing call the CSOFTX3000 records the data related to thetrunkData Collection for Mobile Terminated CallsIf the MS answers a call the visited MSC (VMSC) records all the data related to the calledparty10486981048698If both the calling and called parties are served by the same VMSC the VMSC recordsall the data related to the calling and the called party for producing a mobile originatedcall (MOC) CDR and a mobile terminated call (MTC) CDR10486981048698If the call request comes from another MSC through the trunk then the VMSC throughwhich the called party is served records the data about the call for producing an MTCCDRHUAWEI CSOFTX3000CDR Description 2 CDR ProducingIssue 03 (2007-11-30) Huawei Technologies Proprietary 2-3

23 Producing of CDRWhen a call completes or the duration of the call reaches the threshold for a long-durationcall or the call type changes the CSOFTX3000 records the following data10486981048698Call start date and time10486981048698Duration10486981048698CDR type (such as MOC or MTC)10486981048698Call termination reason (such as normal release or conversation timeout)The CSOFTX3000 also collects data related to the CDRs such as serial number of the CDRsserial number of the initial CDR record types (such as First Bill Last Bill or IntermediateBill) The data is used for CDR managementAfter collecting all the CDR data the CDRs are produced based on the collected data and arestored in the bill poolThe CDRs for intelligent users and common users are produced differently

231 Producing of Ordinary Service CDRThe overall process of producing CDRs for an ordinary service user is as follows1 In the call process the call processing module collects the billing information such asuser number call start time call duration and call attributes2 When the call is terminated the module records the call end time and generates theoriginal CDRs for this call3 The module then sends the original CDRs to the iGWB4 The iGWB processes the CDRs and produces the final CDR5 The billing center collects the final CDR from the iGWB and sorts the CDR according tothe charging policy of specific operators The billing center then generates the telephonebill for the end user2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-4 Huawei Technologies Proprietary Issue 03 (2007-11-30)

In an intelligent call the SSP need not produce the CDRs because the SSP providesinformation only about the call for the SCP The CSOFTX3000 acting as an SSP produces anordinary service CDR for an intelligent call to allow a cross-check mechanism for theoperators It also adds an intelligent service tag to the CDR for the billing center

24 CDR StorageThe WCCUWCSU in the CSOFTX3000 stores the CDRs in the first-in-first-out (FIFO)modeThe CSOFTX3000 stores the CDRs in the bill pool and sends them to the iGWB in real timeThe space of a CDR in the bill pool is not released until the CDR reaches the iGWB

25 CDR Processing on iGWBThe information collected on the CSOFTX3000 is stored in the CDR pool and sent to theiGWB for processingThe iGWB receives the original CDR from the CSOFTX3000 over its self-defined protocolThe iGWB relies on a dual-machine hardware backup to guarantee correct billing informationwithout losing or repeating a CDRSorted CDRs are stored in different directories to be collected by the billing center Afterprocessing the original CDR the iGWB produces the final CDR The processing flow isshown in Figure 2-10HUAWEI CSOFTX3000CDR Description 2 CDR ProducingIssue 03 (2007-11-30) Huawei Technologies Proprietary 2-13Figure 2-10 CDR processing flowSortingFormatConversionOriginalCDRFinalCDRCDR Sorting

CDR sorting classifies CDRs of different billing conditions into different groups to processand save them to different physical paths You can define the criteria according to the datafields in the CDR Here the data fields can act as the criteria for the sortingCDR Format ConversionThe format of a specific CDR is related to the version of the equipment In the appendix ofversion release notes the CDR format and samples are provided for your referenceYou can ask Huawei support engineers to provide correct documents about related equipment versions

26 CDR SendingTo increase the reliability of the bill pool and to send the CDRs to the iGWB theCSOFTX3000 uses the sliding window transfer protocol This protocol ensures a timelyaccurate and continuous transfer In this case no CDR is lost or sent repeatedlyThe process to send a CDR is as follows1 The iGWB and bill pool negotiates the start serial number for the CDRs to be sentthrough handshake messages2 After receiving the CDRs the iGWB returns a response to the bill pool indicating that ithas received the negotiated CDRs3 If a correct reply is not received after sending a batch of CDRs the bill pool does notsend the next batch but resends the first CDR of the same batch4 If the correct reply is received the bill pool sends the CDRs of the next batch2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-14 Huawei Technologies Proprietary Issue 03 (2007-11-30)

27 CDR CheckingTo ensure that the CDRs are correct the CSOFTX3000 carries out a cyclic redundancy check(CRC) when producing sending and receiving the CDRs10486981048698Before storing the CDRs in the bill pool the CSOFTX3000 carries out a CRC check andstores the checksum in the bill pool10486981048698After receiving the CDRs the iGWB performs a CRC When the check fails thegateway assumes that the bills have changed during transfer When converting theoriginal CDRs to the final CDRs the gateway stores the final CDRs to another directoryHere the final CDRs result from the original CDRs that fail in the CRC Themaintenance staff then handles the final CDRsHUAWEI CSOFTX3000CDR Description 3 CDR Types and FormatsIssue 03 (2007-11-30) Huawei Technologies Proprietary 3-1

311 CDR Classification by StorageOriginal CDROriginal CDR is the billing data unit generated and stored on the CSOFTX3000WCCUWCSU The CSOFTX3000 generates and sends the original CDRs to the iGWB inreal-time through an Ethernet connectionFinal CDRUpon receiving the original CDR from the CSOFTX3000 WCCUWCSU the iGWB storesthe CDRs on the hard disk sorts the CDRs and then converts the CDR data format Thesorted and converted CDRs are stored on the hard disk according to certain rules and arecalled the final CDR The services providers charge the end users based on the final CDRs

312 CDR Classification by Call ProcessCDRs of the CSOFTX3000 are classified into two types according to the producing processIntermediate CDRIf the duration of a call exceeds the threshold of the long-duration call timer of theCSOFTX3000 a CDR is produced in each cycle of the timer This CDR is called theintermediate CDRTerminative CDRTerminative CDR is the original CDR which is generated when a call is terminated and theresource is released by the systemA terminative CDR is produced if the duration of a call is shorter than the timer This CDRrecords the information of the entire call process In case the duration of a call is longer thanthe timer an intermediate CDR and a terminative CDR are produced The terminative CDRhowever records only the information collected within the time of the last long-duration calltimerEach intermediate CDR of the CSOFTX3000 records only the information collected in thetime of the long-duration call timer that corresponds to the CDR At the billing center all theintermediate CDRs and the terminative CDR are added up to calculate the actual sum whichis charged for the callHUAWEI CSOFTX3000CDR Description 3 CDR Types and FormatsIssue 03 (2007-11-30) Huawei Technologies Proprietary 3-3

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

21 General Process of CDR ProducingIn each call process the CSOFTX3000 collects information about the call to generate theoriginal CDRs for final charging and settlement by network operators or service providersThe process to produce CDRs is as follows1 The CSOFTX3000 collects the call data to generate the original CDRs and stores them inthe bill pool2 The CSOFTX3000 sends the original CDRs in real time to the charging gateway (iGWB)through the local area network (LAN)3 The iGWB produces the final CDRs and sends them to the billing center4 The public land mobile network (PLMN) operator produces detailed service bills for theend users based on the final CDRsThe entire process of producing a CDR comprises the collecting of information producing theCDR storing the CDR and transferring the CDR

22 Call Data CollectionWhen a mobile subscriber originates or answers a call the CSOFTX3000 records all theinformation about the callData Collection for Mobile Originated Calls

When the call request is sent to the CSOFTX3000 the CSOFTX3000 records all theinformation related to the calling party such as the calling number international mobilestation identity (IMSI) and location (home MSC BSC and cell)The CSOFTX3000 also records all the information related to the called party after analyzingthe called number If it is an outgoing call the CSOFTX3000 records the data related to thetrunkData Collection for Mobile Terminated CallsIf the MS answers a call the visited MSC (VMSC) records all the data related to the calledparty10486981048698If both the calling and called parties are served by the same VMSC the VMSC recordsall the data related to the calling and the called party for producing a mobile originatedcall (MOC) CDR and a mobile terminated call (MTC) CDR10486981048698If the call request comes from another MSC through the trunk then the VMSC throughwhich the called party is served records the data about the call for producing an MTCCDRHUAWEI CSOFTX3000CDR Description 2 CDR ProducingIssue 03 (2007-11-30) Huawei Technologies Proprietary 2-3

23 Producing of CDRWhen a call completes or the duration of the call reaches the threshold for a long-durationcall or the call type changes the CSOFTX3000 records the following data10486981048698Call start date and time10486981048698Duration10486981048698CDR type (such as MOC or MTC)10486981048698Call termination reason (such as normal release or conversation timeout)The CSOFTX3000 also collects data related to the CDRs such as serial number of the CDRsserial number of the initial CDR record types (such as First Bill Last Bill or IntermediateBill) The data is used for CDR managementAfter collecting all the CDR data the CDRs are produced based on the collected data and arestored in the bill poolThe CDRs for intelligent users and common users are produced differently

231 Producing of Ordinary Service CDRThe overall process of producing CDRs for an ordinary service user is as follows1 In the call process the call processing module collects the billing information such asuser number call start time call duration and call attributes2 When the call is terminated the module records the call end time and generates theoriginal CDRs for this call3 The module then sends the original CDRs to the iGWB4 The iGWB processes the CDRs and produces the final CDR5 The billing center collects the final CDR from the iGWB and sorts the CDR according tothe charging policy of specific operators The billing center then generates the telephonebill for the end user2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-4 Huawei Technologies Proprietary Issue 03 (2007-11-30)

BillingCenterSettlementCenterSSPSCPSMPSettlement resultand remote CDRBilling infoCDR managementCall start Call endCDRSMP service management point SCP service control point SSP service switching pointWhen processing an intelligent call the SSP (Service Switching Point) accomplishes theconnection and play of prompt tones according to instructions given by the SCP (ServiceControl Point) The SCP determines whether to conduct billing on a specific call according tothe relevant business policiesThe overall process of producing CDRs for an intelligent service user is as follows1 The SSP reports the O_ANSWERT_ANSWER event when a call is triggered The SCPthen starts the billing process2 The SSP reports the O_DISCONNECTT_DISCONNECT event when the call isterminated3 According to the information contained in the events reported by the SSP the SCPmonitors the recording of the billing information and generates the original CDR4 At the same time the SSP generates a CDR that carries an intelligent service tag for theSCP to double-check the billing informationIn certain scenarios the following processes are involved1 The SCP transfers the CDR to the SMP (Service Management Point)2 The SMP then forwards the CDR to the settlement center3 The settlement center allocates the sum sorts the CDRs and then sends the CDRs withthe allocated sums to different billing centersIn the entire process of an intelligent call the SCP may conduct real-time charging and deductthe sum from the user account directly or may conduct the charging after the call isterminatedHUAWEI CSOFTX3000CDR Description 2 CDR ProducingIssue 03 (2007-11-30) Huawei Technologies Proprietary 2-5Control Mechanism Involved with Intelligent Service BillingBilling for intelligent services includes local intelligent calls and toll intelligent calls Thebilling policy is subject to the service administration entity and the service subscriber TheSCP is the entity that implements the billing while the SSP is the entity that reports the billinginformation The settlement center is responsible for allocating the sum to different billingpartiesThe two intelligent call triggers installed on the SSP are as follows10486981048698O_ANSWERT_ANSWER trigger When an intelligent call starts the SSP reports to theSCP an event that contains the start time billing ID and billing user ID10486981048698O_DISCONNECTT_DISCONNECT trigger When an intelligent call terminates theSSP reports to the SCP an event that contains the termination time billing ID and billinguser ID of the callThe SSP reports various call events to the SCP according to the setting of the triggers TheSCP then conducts billing according to the reported events and forwards the CDRs to the SMPif an allocation is required The SMP forwards the allocated sum to the settlement center forfinal chargingGeneral Principle of Producing Intelligent CDRs

In an intelligent call the SSP need not produce the CDRs because the SSP providesinformation only about the call for the SCP The CSOFTX3000 acting as an SSP produces anordinary service CDR for an intelligent call to allow a cross-check mechanism for theoperators It also adds an intelligent service tag to the CDR for the billing center

24 CDR StorageThe WCCUWCSU in the CSOFTX3000 stores the CDRs in the first-in-first-out (FIFO)modeThe CSOFTX3000 stores the CDRs in the bill pool and sends them to the iGWB in real timeThe space of a CDR in the bill pool is not released until the CDR reaches the iGWB

CDR sorting classifies CDRs of different billing conditions into different groups to processand save them to different physical paths You can define the criteria according to the datafields in the CDR Here the data fields can act as the criteria for the sortingCDR Format ConversionThe format of a specific CDR is related to the version of the equipment In the appendix ofversion release notes the CDR format and samples are provided for your referenceYou can ask Huawei support engineers to provide correct documents about related equipment versions

26 CDR SendingTo increase the reliability of the bill pool and to send the CDRs to the iGWB theCSOFTX3000 uses the sliding window transfer protocol This protocol ensures a timelyaccurate and continuous transfer In this case no CDR is lost or sent repeatedlyThe process to send a CDR is as follows1 The iGWB and bill pool negotiates the start serial number for the CDRs to be sentthrough handshake messages2 After receiving the CDRs the iGWB returns a response to the bill pool indicating that ithas received the negotiated CDRs3 If a correct reply is not received after sending a batch of CDRs the bill pool does notsend the next batch but resends the first CDR of the same batch4 If the correct reply is received the bill pool sends the CDRs of the next batch2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-14 Huawei Technologies Proprietary Issue 03 (2007-11-30)

27 CDR CheckingTo ensure that the CDRs are correct the CSOFTX3000 carries out a cyclic redundancy check(CRC) when producing sending and receiving the CDRs10486981048698Before storing the CDRs in the bill pool the CSOFTX3000 carries out a CRC check andstores the checksum in the bill pool10486981048698After receiving the CDRs the iGWB performs a CRC When the check fails thegateway assumes that the bills have changed during transfer When converting theoriginal CDRs to the final CDRs the gateway stores the final CDRs to another directoryHere the final CDRs result from the original CDRs that fail in the CRC Themaintenance staff then handles the final CDRsHUAWEI CSOFTX3000CDR Description 3 CDR Types and FormatsIssue 03 (2007-11-30) Huawei Technologies Proprietary 3-1

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

21 General Process of CDR ProducingIn each call process the CSOFTX3000 collects information about the call to generate theoriginal CDRs for final charging and settlement by network operators or service providersThe process to produce CDRs is as follows1 The CSOFTX3000 collects the call data to generate the original CDRs and stores them inthe bill pool2 The CSOFTX3000 sends the original CDRs in real time to the charging gateway (iGWB)through the local area network (LAN)3 The iGWB produces the final CDRs and sends them to the billing center4 The public land mobile network (PLMN) operator produces detailed service bills for theend users based on the final CDRsThe entire process of producing a CDR comprises the collecting of information producing theCDR storing the CDR and transferring the CDR

22 Call Data CollectionWhen a mobile subscriber originates or answers a call the CSOFTX3000 records all theinformation about the callData Collection for Mobile Originated Calls

When the call request is sent to the CSOFTX3000 the CSOFTX3000 records all theinformation related to the calling party such as the calling number international mobilestation identity (IMSI) and location (home MSC BSC and cell)The CSOFTX3000 also records all the information related to the called party after analyzingthe called number If it is an outgoing call the CSOFTX3000 records the data related to thetrunkData Collection for Mobile Terminated CallsIf the MS answers a call the visited MSC (VMSC) records all the data related to the calledparty10486981048698If both the calling and called parties are served by the same VMSC the VMSC recordsall the data related to the calling and the called party for producing a mobile originatedcall (MOC) CDR and a mobile terminated call (MTC) CDR10486981048698If the call request comes from another MSC through the trunk then the VMSC throughwhich the called party is served records the data about the call for producing an MTCCDRHUAWEI CSOFTX3000CDR Description 2 CDR ProducingIssue 03 (2007-11-30) Huawei Technologies Proprietary 2-3

23 Producing of CDRWhen a call completes or the duration of the call reaches the threshold for a long-durationcall or the call type changes the CSOFTX3000 records the following data10486981048698Call start date and time10486981048698Duration10486981048698CDR type (such as MOC or MTC)10486981048698Call termination reason (such as normal release or conversation timeout)The CSOFTX3000 also collects data related to the CDRs such as serial number of the CDRsserial number of the initial CDR record types (such as First Bill Last Bill or IntermediateBill) The data is used for CDR managementAfter collecting all the CDR data the CDRs are produced based on the collected data and arestored in the bill poolThe CDRs for intelligent users and common users are produced differently

231 Producing of Ordinary Service CDRThe overall process of producing CDRs for an ordinary service user is as follows1 In the call process the call processing module collects the billing information such asuser number call start time call duration and call attributes2 When the call is terminated the module records the call end time and generates theoriginal CDRs for this call3 The module then sends the original CDRs to the iGWB4 The iGWB processes the CDRs and produces the final CDR5 The billing center collects the final CDR from the iGWB and sorts the CDR according tothe charging policy of specific operators The billing center then generates the telephonebill for the end user2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-4 Huawei Technologies Proprietary Issue 03 (2007-11-30)

In an intelligent call the SSP need not produce the CDRs because the SSP providesinformation only about the call for the SCP The CSOFTX3000 acting as an SSP produces anordinary service CDR for an intelligent call to allow a cross-check mechanism for theoperators It also adds an intelligent service tag to the CDR for the billing center

24 CDR StorageThe WCCUWCSU in the CSOFTX3000 stores the CDRs in the first-in-first-out (FIFO)modeThe CSOFTX3000 stores the CDRs in the bill pool and sends them to the iGWB in real timeThe space of a CDR in the bill pool is not released until the CDR reaches the iGWB

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

21 General Process of CDR ProducingIn each call process the CSOFTX3000 collects information about the call to generate theoriginal CDRs for final charging and settlement by network operators or service providersThe process to produce CDRs is as follows1 The CSOFTX3000 collects the call data to generate the original CDRs and stores them inthe bill pool2 The CSOFTX3000 sends the original CDRs in real time to the charging gateway (iGWB)through the local area network (LAN)3 The iGWB produces the final CDRs and sends them to the billing center4 The public land mobile network (PLMN) operator produces detailed service bills for theend users based on the final CDRsThe entire process of producing a CDR comprises the collecting of information producing theCDR storing the CDR and transferring the CDR

22 Call Data CollectionWhen a mobile subscriber originates or answers a call the CSOFTX3000 records all theinformation about the callData Collection for Mobile Originated Calls

When the call request is sent to the CSOFTX3000 the CSOFTX3000 records all theinformation related to the calling party such as the calling number international mobilestation identity (IMSI) and location (home MSC BSC and cell)The CSOFTX3000 also records all the information related to the called party after analyzingthe called number If it is an outgoing call the CSOFTX3000 records the data related to thetrunkData Collection for Mobile Terminated CallsIf the MS answers a call the visited MSC (VMSC) records all the data related to the calledparty10486981048698If both the calling and called parties are served by the same VMSC the VMSC recordsall the data related to the calling and the called party for producing a mobile originatedcall (MOC) CDR and a mobile terminated call (MTC) CDR10486981048698If the call request comes from another MSC through the trunk then the VMSC throughwhich the called party is served records the data about the call for producing an MTCCDRHUAWEI CSOFTX3000CDR Description 2 CDR ProducingIssue 03 (2007-11-30) Huawei Technologies Proprietary 2-3

23 Producing of CDRWhen a call completes or the duration of the call reaches the threshold for a long-durationcall or the call type changes the CSOFTX3000 records the following data10486981048698Call start date and time10486981048698Duration10486981048698CDR type (such as MOC or MTC)10486981048698Call termination reason (such as normal release or conversation timeout)The CSOFTX3000 also collects data related to the CDRs such as serial number of the CDRsserial number of the initial CDR record types (such as First Bill Last Bill or IntermediateBill) The data is used for CDR managementAfter collecting all the CDR data the CDRs are produced based on the collected data and arestored in the bill poolThe CDRs for intelligent users and common users are produced differently

231 Producing of Ordinary Service CDRThe overall process of producing CDRs for an ordinary service user is as follows1 In the call process the call processing module collects the billing information such asuser number call start time call duration and call attributes2 When the call is terminated the module records the call end time and generates theoriginal CDRs for this call3 The module then sends the original CDRs to the iGWB4 The iGWB processes the CDRs and produces the final CDR5 The billing center collects the final CDR from the iGWB and sorts the CDR according tothe charging policy of specific operators The billing center then generates the telephonebill for the end user2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-4 Huawei Technologies Proprietary Issue 03 (2007-11-30)

BillingCenterSettlementCenterSSPSCPSMPSettlement resultand remote CDRBilling infoCDR managementCall start Call endCDRSMP service management point SCP service control point SSP service switching pointWhen processing an intelligent call the SSP (Service Switching Point) accomplishes theconnection and play of prompt tones according to instructions given by the SCP (ServiceControl Point) The SCP determines whether to conduct billing on a specific call according tothe relevant business policiesThe overall process of producing CDRs for an intelligent service user is as follows1 The SSP reports the O_ANSWERT_ANSWER event when a call is triggered The SCPthen starts the billing process2 The SSP reports the O_DISCONNECTT_DISCONNECT event when the call isterminated3 According to the information contained in the events reported by the SSP the SCPmonitors the recording of the billing information and generates the original CDR4 At the same time the SSP generates a CDR that carries an intelligent service tag for theSCP to double-check the billing informationIn certain scenarios the following processes are involved1 The SCP transfers the CDR to the SMP (Service Management Point)2 The SMP then forwards the CDR to the settlement center3 The settlement center allocates the sum sorts the CDRs and then sends the CDRs withthe allocated sums to different billing centersIn the entire process of an intelligent call the SCP may conduct real-time charging and deductthe sum from the user account directly or may conduct the charging after the call isterminatedHUAWEI CSOFTX3000CDR Description 2 CDR ProducingIssue 03 (2007-11-30) Huawei Technologies Proprietary 2-5Control Mechanism Involved with Intelligent Service BillingBilling for intelligent services includes local intelligent calls and toll intelligent calls Thebilling policy is subject to the service administration entity and the service subscriber TheSCP is the entity that implements the billing while the SSP is the entity that reports the billinginformation The settlement center is responsible for allocating the sum to different billingpartiesThe two intelligent call triggers installed on the SSP are as follows10486981048698O_ANSWERT_ANSWER trigger When an intelligent call starts the SSP reports to theSCP an event that contains the start time billing ID and billing user ID10486981048698O_DISCONNECTT_DISCONNECT trigger When an intelligent call terminates theSSP reports to the SCP an event that contains the termination time billing ID and billinguser ID of the callThe SSP reports various call events to the SCP according to the setting of the triggers TheSCP then conducts billing according to the reported events and forwards the CDRs to the SMPif an allocation is required The SMP forwards the allocated sum to the settlement center forfinal chargingGeneral Principle of Producing Intelligent CDRs

In an intelligent call the SSP need not produce the CDRs because the SSP providesinformation only about the call for the SCP The CSOFTX3000 acting as an SSP produces anordinary service CDR for an intelligent call to allow a cross-check mechanism for theoperators It also adds an intelligent service tag to the CDR for the billing center

24 CDR StorageThe WCCUWCSU in the CSOFTX3000 stores the CDRs in the first-in-first-out (FIFO)modeThe CSOFTX3000 stores the CDRs in the bill pool and sends them to the iGWB in real timeThe space of a CDR in the bill pool is not released until the CDR reaches the iGWB

CDR sorting classifies CDRs of different billing conditions into different groups to processand save them to different physical paths You can define the criteria according to the datafields in the CDR Here the data fields can act as the criteria for the sortingCDR Format ConversionThe format of a specific CDR is related to the version of the equipment In the appendix ofversion release notes the CDR format and samples are provided for your referenceYou can ask Huawei support engineers to provide correct documents about related equipment versions

26 CDR SendingTo increase the reliability of the bill pool and to send the CDRs to the iGWB theCSOFTX3000 uses the sliding window transfer protocol This protocol ensures a timelyaccurate and continuous transfer In this case no CDR is lost or sent repeatedlyThe process to send a CDR is as follows1 The iGWB and bill pool negotiates the start serial number for the CDRs to be sentthrough handshake messages2 After receiving the CDRs the iGWB returns a response to the bill pool indicating that ithas received the negotiated CDRs3 If a correct reply is not received after sending a batch of CDRs the bill pool does notsend the next batch but resends the first CDR of the same batch4 If the correct reply is received the bill pool sends the CDRs of the next batch2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-14 Huawei Technologies Proprietary Issue 03 (2007-11-30)

27 CDR CheckingTo ensure that the CDRs are correct the CSOFTX3000 carries out a cyclic redundancy check(CRC) when producing sending and receiving the CDRs10486981048698Before storing the CDRs in the bill pool the CSOFTX3000 carries out a CRC check andstores the checksum in the bill pool10486981048698After receiving the CDRs the iGWB performs a CRC When the check fails thegateway assumes that the bills have changed during transfer When converting theoriginal CDRs to the final CDRs the gateway stores the final CDRs to another directoryHere the final CDRs result from the original CDRs that fail in the CRC Themaintenance staff then handles the final CDRsHUAWEI CSOFTX3000CDR Description 3 CDR Types and FormatsIssue 03 (2007-11-30) Huawei Technologies Proprietary 3-1

311 CDR Classification by StorageOriginal CDROriginal CDR is the billing data unit generated and stored on the CSOFTX3000WCCUWCSU The CSOFTX3000 generates and sends the original CDRs to the iGWB inreal-time through an Ethernet connectionFinal CDRUpon receiving the original CDR from the CSOFTX3000 WCCUWCSU the iGWB storesthe CDRs on the hard disk sorts the CDRs and then converts the CDR data format Thesorted and converted CDRs are stored on the hard disk according to certain rules and arecalled the final CDR The services providers charge the end users based on the final CDRs

312 CDR Classification by Call ProcessCDRs of the CSOFTX3000 are classified into two types according to the producing processIntermediate CDRIf the duration of a call exceeds the threshold of the long-duration call timer of theCSOFTX3000 a CDR is produced in each cycle of the timer This CDR is called theintermediate CDRTerminative CDRTerminative CDR is the original CDR which is generated when a call is terminated and theresource is released by the systemA terminative CDR is produced if the duration of a call is shorter than the timer This CDRrecords the information of the entire call process In case the duration of a call is longer thanthe timer an intermediate CDR and a terminative CDR are produced The terminative CDRhowever records only the information collected within the time of the last long-duration calltimerEach intermediate CDR of the CSOFTX3000 records only the information collected in thetime of the long-duration call timer that corresponds to the CDR At the billing center all theintermediate CDRs and the terminative CDR are added up to calculate the actual sum whichis charged for the callHUAWEI CSOFTX3000CDR Description 3 CDR Types and FormatsIssue 03 (2007-11-30) Huawei Technologies Proprietary 3-3

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

53 CDR Sorting at Billing CenterThe billing center sorts the final CDR and discards CDRs that need not be charged CDRsorting includes the following types10486981048698IN CDR sorting10486981048698Ordinary CDR sorting

531 Sorting of IN CDRsIN CDR sorting is carried out in the following two IN modes10486981048698Target network10486981048698Overlay networkTarget Network ModeThe billing center can identify the IN CDRs according to the IN service identifier and usertypes The relevant value is in the IN service identifier of IN CDRs and the value is invalid inthe IN service identifier of ordinary CDRsOverlay Network ModeThe PPC service in the overlay network requires that IN subscribers have special numbersegment or access code so that the sorting of CDRs can be conducted at the billing centerbased on the following10486981048698The calling number segment or access code in the MOC CDRs from the originatingoffice and10486981048698The called number segment or access code in the MTC CDRs from the called officeHUAWEI CSOFTX3000CDR Description 5 CDR Control and SortingIssue 03 (2007-11-30) Huawei Technologies Proprietary 5-5

532 Sorting of Ordinary CDRsThe sorting of ordinary CDRs is subject to the charging policy of network operatorsFor example at the billing center CDRs can by sorted by types In case a CDR type isemergency call the CDR is deleted

When the call request is sent to the CSOFTX3000 the CSOFTX3000 records all theinformation related to the calling party such as the calling number international mobilestation identity (IMSI) and location (home MSC BSC and cell)The CSOFTX3000 also records all the information related to the called party after analyzingthe called number If it is an outgoing call the CSOFTX3000 records the data related to thetrunkData Collection for Mobile Terminated CallsIf the MS answers a call the visited MSC (VMSC) records all the data related to the calledparty10486981048698If both the calling and called parties are served by the same VMSC the VMSC recordsall the data related to the calling and the called party for producing a mobile originatedcall (MOC) CDR and a mobile terminated call (MTC) CDR10486981048698If the call request comes from another MSC through the trunk then the VMSC throughwhich the called party is served records the data about the call for producing an MTCCDRHUAWEI CSOFTX3000CDR Description 2 CDR ProducingIssue 03 (2007-11-30) Huawei Technologies Proprietary 2-3

23 Producing of CDRWhen a call completes or the duration of the call reaches the threshold for a long-durationcall or the call type changes the CSOFTX3000 records the following data10486981048698Call start date and time10486981048698Duration10486981048698CDR type (such as MOC or MTC)10486981048698Call termination reason (such as normal release or conversation timeout)The CSOFTX3000 also collects data related to the CDRs such as serial number of the CDRsserial number of the initial CDR record types (such as First Bill Last Bill or IntermediateBill) The data is used for CDR managementAfter collecting all the CDR data the CDRs are produced based on the collected data and arestored in the bill poolThe CDRs for intelligent users and common users are produced differently

231 Producing of Ordinary Service CDRThe overall process of producing CDRs for an ordinary service user is as follows1 In the call process the call processing module collects the billing information such asuser number call start time call duration and call attributes2 When the call is terminated the module records the call end time and generates theoriginal CDRs for this call3 The module then sends the original CDRs to the iGWB4 The iGWB processes the CDRs and produces the final CDR5 The billing center collects the final CDR from the iGWB and sorts the CDR according tothe charging policy of specific operators The billing center then generates the telephonebill for the end user2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-4 Huawei Technologies Proprietary Issue 03 (2007-11-30)

In an intelligent call the SSP need not produce the CDRs because the SSP providesinformation only about the call for the SCP The CSOFTX3000 acting as an SSP produces anordinary service CDR for an intelligent call to allow a cross-check mechanism for theoperators It also adds an intelligent service tag to the CDR for the billing center

24 CDR StorageThe WCCUWCSU in the CSOFTX3000 stores the CDRs in the first-in-first-out (FIFO)modeThe CSOFTX3000 stores the CDRs in the bill pool and sends them to the iGWB in real timeThe space of a CDR in the bill pool is not released until the CDR reaches the iGWB

CDR sorting classifies CDRs of different billing conditions into different groups to processand save them to different physical paths You can define the criteria according to the datafields in the CDR Here the data fields can act as the criteria for the sortingCDR Format ConversionThe format of a specific CDR is related to the version of the equipment In the appendix ofversion release notes the CDR format and samples are provided for your referenceYou can ask Huawei support engineers to provide correct documents about related equipment versions

26 CDR SendingTo increase the reliability of the bill pool and to send the CDRs to the iGWB theCSOFTX3000 uses the sliding window transfer protocol This protocol ensures a timelyaccurate and continuous transfer In this case no CDR is lost or sent repeatedlyThe process to send a CDR is as follows1 The iGWB and bill pool negotiates the start serial number for the CDRs to be sentthrough handshake messages2 After receiving the CDRs the iGWB returns a response to the bill pool indicating that ithas received the negotiated CDRs3 If a correct reply is not received after sending a batch of CDRs the bill pool does notsend the next batch but resends the first CDR of the same batch4 If the correct reply is received the bill pool sends the CDRs of the next batch2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-14 Huawei Technologies Proprietary Issue 03 (2007-11-30)

312 CDR Classification by Call ProcessCDRs of the CSOFTX3000 are classified into two types according to the producing processIntermediate CDRIf the duration of a call exceeds the threshold of the long-duration call timer of theCSOFTX3000 a CDR is produced in each cycle of the timer This CDR is called theintermediate CDRTerminative CDRTerminative CDR is the original CDR which is generated when a call is terminated and theresource is released by the systemA terminative CDR is produced if the duration of a call is shorter than the timer This CDRrecords the information of the entire call process In case the duration of a call is longer thanthe timer an intermediate CDR and a terminative CDR are produced The terminative CDRhowever records only the information collected within the time of the last long-duration calltimerEach intermediate CDR of the CSOFTX3000 records only the information collected in thetime of the long-duration call timer that corresponds to the CDR At the billing center all theintermediate CDRs and the terminative CDR are added up to calculate the actual sum whichis charged for the callHUAWEI CSOFTX3000CDR Description 3 CDR Types and FormatsIssue 03 (2007-11-30) Huawei Technologies Proprietary 3-3

313 CDR Classification By ScenarioMOC CDR and MTC CDRWhen an MS originates a call and the called party answers an MOC CDR is produced duringthe call or when the call is terminatedWhen an MS terminates a call an MTC CDR is produced during the call or when the callterminatesRoam CDRThe roam CDR is generated at the GMSC for a call from a public switched telephone network(PSTN) or another mobile network to the serving network The roam CDR is a chargingreference for the PSTN or another mobile network The roam CDR is also a reference forsettling trunk occupation expenses between the serving network and the PSTN or between

two mobile networksYou can decide whether to generate the roam CDR through data configurationFor details see 51 Control on the Producing of CDRsTransit CDRThe transit CDR is produced on the CSOFTX3000 when10486981048698A call is routed to the CSOFTX3000 but the call is neither originated from norterminated at the CSOFTX3000 and10486981048698Both the outgoing and the incoming directions of the call are the CSOFTX3000Transit CDRs are not produced for calls forwarded by the local CSOFTX3000You can decide whether to generate the transit CDR by configuring dataGateway_Outgoing CDRA gateway outgoing CDR is generated when10486981048698A call reaches another mobile network from a gateway office10486981048698A call reaches the PSTN from a gateway officeThe gateway outgoing CDR is a reference for billing in the following cases10486981048698Settlement of trunk occupation between the serving PLMN and the PSTN10486981048698Settlement of trunk occupation between two mobile networksYou can decide whether to generate the gateway outgoing CDR by configuring dataCFW CDRA call forwarding (CFW) CDR is produced when the call forwarding service is triggered Thecall forwarding service enables a call to be forwarded to another specified numberA CFW CDR covers three parties10486981048698A calling party3 CDR Types and FormatsHUAWEI CSOFTX3000CDR Description3-4 Huawei Technologies Proprietary Issue 03 (2007-11-30)10486981048698An original called party (the subscriber who forwards the call)10486981048698A final called party (the subscriber who finally answers the call)The CFW CDR charges only the original called party In the CFW CDR10486981048698The calling party is the subscriber who forwards the call10486981048698The called party is the subscriber who finally answers the call10486981048698The third-party is the calling party10486981048698The IMSI and mobile directory number (MDN) contain the attributes of the originalcalled partyThe CFW CDR also displays the call forwarding type which includes the following10486981048698Call forwardingndashunconditional (CFU)10486981048698Call forwardingndashbusy (CFB)10486981048698Call forwardingndashno answer (CFNA)10486981048698Call forwardingndashdefault (CFD)MO_SMS CDR and MT_SMS CDRAn MO_SMS CDR is produced for the subscriber who sends the message and an MT_SMSCDR is produced for the subscriber who receives the message An SMS CDR does notdistinguish IN subscribers from ordinary subscribersIn the SMS mode the handset transmits characters through the signaling channel or voicechannel Different from the ordinary CDR the MO_SMS CDR and MT_SMS CDR containthe following fields10486981048698Number of bytesThis field indicates the number of bytes in the UserPart within the short message that is thelength of the content after it is decoded10486981048698Address of the message centerThis field indicates the message center through which the short message travels In the CDMA

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

In an intelligent call the SSP need not produce the CDRs because the SSP providesinformation only about the call for the SCP The CSOFTX3000 acting as an SSP produces anordinary service CDR for an intelligent call to allow a cross-check mechanism for theoperators It also adds an intelligent service tag to the CDR for the billing center

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

53 CDR Sorting at Billing CenterThe billing center sorts the final CDR and discards CDRs that need not be charged CDRsorting includes the following types10486981048698IN CDR sorting10486981048698Ordinary CDR sorting

531 Sorting of IN CDRsIN CDR sorting is carried out in the following two IN modes10486981048698Target network10486981048698Overlay networkTarget Network ModeThe billing center can identify the IN CDRs according to the IN service identifier and usertypes The relevant value is in the IN service identifier of IN CDRs and the value is invalid inthe IN service identifier of ordinary CDRsOverlay Network ModeThe PPC service in the overlay network requires that IN subscribers have special numbersegment or access code so that the sorting of CDRs can be conducted at the billing centerbased on the following10486981048698The calling number segment or access code in the MOC CDRs from the originatingoffice and10486981048698The called number segment or access code in the MTC CDRs from the called officeHUAWEI CSOFTX3000CDR Description 5 CDR Control and SortingIssue 03 (2007-11-30) Huawei Technologies Proprietary 5-5

532 Sorting of Ordinary CDRsThe sorting of ordinary CDRs is subject to the charging policy of network operatorsFor example at the billing center CDRs can by sorted by types In case a CDR type isemergency call the CDR is deleted

In an intelligent call the SSP need not produce the CDRs because the SSP providesinformation only about the call for the SCP The CSOFTX3000 acting as an SSP produces anordinary service CDR for an intelligent call to allow a cross-check mechanism for theoperators It also adds an intelligent service tag to the CDR for the billing center

24 CDR StorageThe WCCUWCSU in the CSOFTX3000 stores the CDRs in the first-in-first-out (FIFO)modeThe CSOFTX3000 stores the CDRs in the bill pool and sends them to the iGWB in real timeThe space of a CDR in the bill pool is not released until the CDR reaches the iGWB

CDR sorting classifies CDRs of different billing conditions into different groups to processand save them to different physical paths You can define the criteria according to the datafields in the CDR Here the data fields can act as the criteria for the sortingCDR Format ConversionThe format of a specific CDR is related to the version of the equipment In the appendix ofversion release notes the CDR format and samples are provided for your referenceYou can ask Huawei support engineers to provide correct documents about related equipment versions

26 CDR SendingTo increase the reliability of the bill pool and to send the CDRs to the iGWB theCSOFTX3000 uses the sliding window transfer protocol This protocol ensures a timelyaccurate and continuous transfer In this case no CDR is lost or sent repeatedlyThe process to send a CDR is as follows1 The iGWB and bill pool negotiates the start serial number for the CDRs to be sentthrough handshake messages2 After receiving the CDRs the iGWB returns a response to the bill pool indicating that ithas received the negotiated CDRs3 If a correct reply is not received after sending a batch of CDRs the bill pool does notsend the next batch but resends the first CDR of the same batch4 If the correct reply is received the bill pool sends the CDRs of the next batch2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-14 Huawei Technologies Proprietary Issue 03 (2007-11-30)

27 CDR CheckingTo ensure that the CDRs are correct the CSOFTX3000 carries out a cyclic redundancy check(CRC) when producing sending and receiving the CDRs10486981048698Before storing the CDRs in the bill pool the CSOFTX3000 carries out a CRC check andstores the checksum in the bill pool10486981048698After receiving the CDRs the iGWB performs a CRC When the check fails thegateway assumes that the bills have changed during transfer When converting theoriginal CDRs to the final CDRs the gateway stores the final CDRs to another directoryHere the final CDRs result from the original CDRs that fail in the CRC Themaintenance staff then handles the final CDRsHUAWEI CSOFTX3000CDR Description 3 CDR Types and FormatsIssue 03 (2007-11-30) Huawei Technologies Proprietary 3-1

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

CDR sorting classifies CDRs of different billing conditions into different groups to processand save them to different physical paths You can define the criteria according to the datafields in the CDR Here the data fields can act as the criteria for the sortingCDR Format ConversionThe format of a specific CDR is related to the version of the equipment In the appendix ofversion release notes the CDR format and samples are provided for your referenceYou can ask Huawei support engineers to provide correct documents about related equipment versions

26 CDR SendingTo increase the reliability of the bill pool and to send the CDRs to the iGWB theCSOFTX3000 uses the sliding window transfer protocol This protocol ensures a timelyaccurate and continuous transfer In this case no CDR is lost or sent repeatedlyThe process to send a CDR is as follows1 The iGWB and bill pool negotiates the start serial number for the CDRs to be sentthrough handshake messages2 After receiving the CDRs the iGWB returns a response to the bill pool indicating that ithas received the negotiated CDRs3 If a correct reply is not received after sending a batch of CDRs the bill pool does notsend the next batch but resends the first CDR of the same batch4 If the correct reply is received the bill pool sends the CDRs of the next batch2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-14 Huawei Technologies Proprietary Issue 03 (2007-11-30)

27 CDR CheckingTo ensure that the CDRs are correct the CSOFTX3000 carries out a cyclic redundancy check(CRC) when producing sending and receiving the CDRs10486981048698Before storing the CDRs in the bill pool the CSOFTX3000 carries out a CRC check andstores the checksum in the bill pool10486981048698After receiving the CDRs the iGWB performs a CRC When the check fails thegateway assumes that the bills have changed during transfer When converting theoriginal CDRs to the final CDRs the gateway stores the final CDRs to another directoryHere the final CDRs result from the original CDRs that fail in the CRC Themaintenance staff then handles the final CDRsHUAWEI CSOFTX3000CDR Description 3 CDR Types and FormatsIssue 03 (2007-11-30) Huawei Technologies Proprietary 3-1

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

CDR sorting classifies CDRs of different billing conditions into different groups to processand save them to different physical paths You can define the criteria according to the datafields in the CDR Here the data fields can act as the criteria for the sortingCDR Format ConversionThe format of a specific CDR is related to the version of the equipment In the appendix ofversion release notes the CDR format and samples are provided for your referenceYou can ask Huawei support engineers to provide correct documents about related equipment versions

26 CDR SendingTo increase the reliability of the bill pool and to send the CDRs to the iGWB theCSOFTX3000 uses the sliding window transfer protocol This protocol ensures a timelyaccurate and continuous transfer In this case no CDR is lost or sent repeatedlyThe process to send a CDR is as follows1 The iGWB and bill pool negotiates the start serial number for the CDRs to be sentthrough handshake messages2 After receiving the CDRs the iGWB returns a response to the bill pool indicating that ithas received the negotiated CDRs3 If a correct reply is not received after sending a batch of CDRs the bill pool does notsend the next batch but resends the first CDR of the same batch4 If the correct reply is received the bill pool sends the CDRs of the next batch2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-14 Huawei Technologies Proprietary Issue 03 (2007-11-30)

27 CDR CheckingTo ensure that the CDRs are correct the CSOFTX3000 carries out a cyclic redundancy check(CRC) when producing sending and receiving the CDRs10486981048698Before storing the CDRs in the bill pool the CSOFTX3000 carries out a CRC check andstores the checksum in the bill pool10486981048698After receiving the CDRs the iGWB performs a CRC When the check fails thegateway assumes that the bills have changed during transfer When converting theoriginal CDRs to the final CDRs the gateway stores the final CDRs to another directoryHere the final CDRs result from the original CDRs that fail in the CRC Themaintenance staff then handles the final CDRsHUAWEI CSOFTX3000CDR Description 3 CDR Types and FormatsIssue 03 (2007-11-30) Huawei Technologies Proprietary 3-1

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

53 CDR Sorting at Billing CenterThe billing center sorts the final CDR and discards CDRs that need not be charged CDRsorting includes the following types10486981048698IN CDR sorting10486981048698Ordinary CDR sorting

531 Sorting of IN CDRsIN CDR sorting is carried out in the following two IN modes10486981048698Target network10486981048698Overlay networkTarget Network ModeThe billing center can identify the IN CDRs according to the IN service identifier and usertypes The relevant value is in the IN service identifier of IN CDRs and the value is invalid inthe IN service identifier of ordinary CDRsOverlay Network ModeThe PPC service in the overlay network requires that IN subscribers have special numbersegment or access code so that the sorting of CDRs can be conducted at the billing centerbased on the following10486981048698The calling number segment or access code in the MOC CDRs from the originatingoffice and10486981048698The called number segment or access code in the MTC CDRs from the called officeHUAWEI CSOFTX3000CDR Description 5 CDR Control and SortingIssue 03 (2007-11-30) Huawei Technologies Proprietary 5-5

532 Sorting of Ordinary CDRsThe sorting of ordinary CDRs is subject to the charging policy of network operatorsFor example at the billing center CDRs can by sorted by types In case a CDR type isemergency call the CDR is deleted

CDR sorting classifies CDRs of different billing conditions into different groups to processand save them to different physical paths You can define the criteria according to the datafields in the CDR Here the data fields can act as the criteria for the sortingCDR Format ConversionThe format of a specific CDR is related to the version of the equipment In the appendix ofversion release notes the CDR format and samples are provided for your referenceYou can ask Huawei support engineers to provide correct documents about related equipment versions

26 CDR SendingTo increase the reliability of the bill pool and to send the CDRs to the iGWB theCSOFTX3000 uses the sliding window transfer protocol This protocol ensures a timelyaccurate and continuous transfer In this case no CDR is lost or sent repeatedlyThe process to send a CDR is as follows1 The iGWB and bill pool negotiates the start serial number for the CDRs to be sentthrough handshake messages2 After receiving the CDRs the iGWB returns a response to the bill pool indicating that ithas received the negotiated CDRs3 If a correct reply is not received after sending a batch of CDRs the bill pool does notsend the next batch but resends the first CDR of the same batch4 If the correct reply is received the bill pool sends the CDRs of the next batch2 CDR ProducingHUAWEI CSOFTX3000CDR Description2-14 Huawei Technologies Proprietary Issue 03 (2007-11-30)

27 CDR CheckingTo ensure that the CDRs are correct the CSOFTX3000 carries out a cyclic redundancy check(CRC) when producing sending and receiving the CDRs10486981048698Before storing the CDRs in the bill pool the CSOFTX3000 carries out a CRC check andstores the checksum in the bill pool10486981048698After receiving the CDRs the iGWB performs a CRC When the check fails thegateway assumes that the bills have changed during transfer When converting theoriginal CDRs to the final CDRs the gateway stores the final CDRs to another directoryHere the final CDRs result from the original CDRs that fail in the CRC Themaintenance staff then handles the final CDRsHUAWEI CSOFTX3000CDR Description 3 CDR Types and FormatsIssue 03 (2007-11-30) Huawei Technologies Proprietary 3-1

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

53 CDR Sorting at Billing CenterThe billing center sorts the final CDR and discards CDRs that need not be charged CDRsorting includes the following types10486981048698IN CDR sorting10486981048698Ordinary CDR sorting

531 Sorting of IN CDRsIN CDR sorting is carried out in the following two IN modes10486981048698Target network10486981048698Overlay networkTarget Network ModeThe billing center can identify the IN CDRs according to the IN service identifier and usertypes The relevant value is in the IN service identifier of IN CDRs and the value is invalid inthe IN service identifier of ordinary CDRsOverlay Network ModeThe PPC service in the overlay network requires that IN subscribers have special numbersegment or access code so that the sorting of CDRs can be conducted at the billing centerbased on the following10486981048698The calling number segment or access code in the MOC CDRs from the originatingoffice and10486981048698The called number segment or access code in the MTC CDRs from the called officeHUAWEI CSOFTX3000CDR Description 5 CDR Control and SortingIssue 03 (2007-11-30) Huawei Technologies Proprietary 5-5

31 CDR TypesThis section introduces the following three types of CDRs10486981048698CDRs according to storage original CDRs and final CDRs10486981048698CDRs according to producing process intermediate CDR and terminative CDR10486981048698CDRs produced according to service type or call modes

311 CDR Classification by StorageOriginal CDROriginal CDR is the billing data unit generated and stored on the CSOFTX3000WCCUWCSU The CSOFTX3000 generates and sends the original CDRs to the iGWB inreal-time through an Ethernet connectionFinal CDRUpon receiving the original CDR from the CSOFTX3000 WCCUWCSU the iGWB storesthe CDRs on the hard disk sorts the CDRs and then converts the CDR data format Thesorted and converted CDRs are stored on the hard disk according to certain rules and arecalled the final CDR The services providers charge the end users based on the final CDRs

312 CDR Classification by Call ProcessCDRs of the CSOFTX3000 are classified into two types according to the producing processIntermediate CDRIf the duration of a call exceeds the threshold of the long-duration call timer of theCSOFTX3000 a CDR is produced in each cycle of the timer This CDR is called theintermediate CDRTerminative CDRTerminative CDR is the original CDR which is generated when a call is terminated and theresource is released by the systemA terminative CDR is produced if the duration of a call is shorter than the timer This CDRrecords the information of the entire call process In case the duration of a call is longer thanthe timer an intermediate CDR and a terminative CDR are produced The terminative CDRhowever records only the information collected within the time of the last long-duration calltimerEach intermediate CDR of the CSOFTX3000 records only the information collected in thetime of the long-duration call timer that corresponds to the CDR At the billing center all theintermediate CDRs and the terminative CDR are added up to calculate the actual sum whichis charged for the callHUAWEI CSOFTX3000CDR Description 3 CDR Types and FormatsIssue 03 (2007-11-30) Huawei Technologies Proprietary 3-3

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

531 Sorting of IN CDRsIN CDR sorting is carried out in the following two IN modes10486981048698Target network10486981048698Overlay networkTarget Network ModeThe billing center can identify the IN CDRs according to the IN service identifier and usertypes The relevant value is in the IN service identifier of IN CDRs and the value is invalid inthe IN service identifier of ordinary CDRsOverlay Network ModeThe PPC service in the overlay network requires that IN subscribers have special numbersegment or access code so that the sorting of CDRs can be conducted at the billing centerbased on the following10486981048698The calling number segment or access code in the MOC CDRs from the originatingoffice and10486981048698The called number segment or access code in the MTC CDRs from the called officeHUAWEI CSOFTX3000CDR Description 5 CDR Control and SortingIssue 03 (2007-11-30) Huawei Technologies Proprietary 5-5

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

53 CDR Sorting at Billing CenterThe billing center sorts the final CDR and discards CDRs that need not be charged CDRsorting includes the following types10486981048698IN CDR sorting10486981048698Ordinary CDR sorting

531 Sorting of IN CDRsIN CDR sorting is carried out in the following two IN modes10486981048698Target network10486981048698Overlay networkTarget Network ModeThe billing center can identify the IN CDRs according to the IN service identifier and usertypes The relevant value is in the IN service identifier of IN CDRs and the value is invalid inthe IN service identifier of ordinary CDRsOverlay Network ModeThe PPC service in the overlay network requires that IN subscribers have special numbersegment or access code so that the sorting of CDRs can be conducted at the billing centerbased on the following10486981048698The calling number segment or access code in the MOC CDRs from the originatingoffice and10486981048698The called number segment or access code in the MTC CDRs from the called officeHUAWEI CSOFTX3000CDR Description 5 CDR Control and SortingIssue 03 (2007-11-30) Huawei Technologies Proprietary 5-5

532 Sorting of Ordinary CDRsThe sorting of ordinary CDRs is subject to the charging policy of network operatorsFor example at the billing center CDRs can by sorted by types In case a CDR type isemergency call the CDR is deleted

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

53 CDR Sorting at Billing CenterThe billing center sorts the final CDR and discards CDRs that need not be charged CDRsorting includes the following types10486981048698IN CDR sorting10486981048698Ordinary CDR sorting

531 Sorting of IN CDRsIN CDR sorting is carried out in the following two IN modes10486981048698Target network10486981048698Overlay networkTarget Network ModeThe billing center can identify the IN CDRs according to the IN service identifier and usertypes The relevant value is in the IN service identifier of IN CDRs and the value is invalid inthe IN service identifier of ordinary CDRsOverlay Network ModeThe PPC service in the overlay network requires that IN subscribers have special numbersegment or access code so that the sorting of CDRs can be conducted at the billing centerbased on the following10486981048698The calling number segment or access code in the MOC CDRs from the originatingoffice and10486981048698The called number segment or access code in the MTC CDRs from the called officeHUAWEI CSOFTX3000CDR Description 5 CDR Control and SortingIssue 03 (2007-11-30) Huawei Technologies Proprietary 5-5

532 Sorting of Ordinary CDRsThe sorting of ordinary CDRs is subject to the charging policy of network operatorsFor example at the billing center CDRs can by sorted by types In case a CDR type isemergency call the CDR is deleted

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

53 CDR Sorting at Billing CenterThe billing center sorts the final CDR and discards CDRs that need not be charged CDRsorting includes the following types10486981048698IN CDR sorting10486981048698Ordinary CDR sorting

531 Sorting of IN CDRsIN CDR sorting is carried out in the following two IN modes10486981048698Target network10486981048698Overlay networkTarget Network ModeThe billing center can identify the IN CDRs according to the IN service identifier and usertypes The relevant value is in the IN service identifier of IN CDRs and the value is invalid inthe IN service identifier of ordinary CDRsOverlay Network ModeThe PPC service in the overlay network requires that IN subscribers have special numbersegment or access code so that the sorting of CDRs can be conducted at the billing centerbased on the following10486981048698The calling number segment or access code in the MOC CDRs from the originatingoffice and10486981048698The called number segment or access code in the MTC CDRs from the called officeHUAWEI CSOFTX3000CDR Description 5 CDR Control and SortingIssue 03 (2007-11-30) Huawei Technologies Proprietary 5-5

532 Sorting of Ordinary CDRsThe sorting of ordinary CDRs is subject to the charging policy of network operatorsFor example at the billing center CDRs can by sorted by types In case a CDR type isemergency call the CDR is deleted

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

53 CDR Sorting at Billing CenterThe billing center sorts the final CDR and discards CDRs that need not be charged CDRsorting includes the following types10486981048698IN CDR sorting10486981048698Ordinary CDR sorting

531 Sorting of IN CDRsIN CDR sorting is carried out in the following two IN modes10486981048698Target network10486981048698Overlay networkTarget Network ModeThe billing center can identify the IN CDRs according to the IN service identifier and usertypes The relevant value is in the IN service identifier of IN CDRs and the value is invalid inthe IN service identifier of ordinary CDRsOverlay Network ModeThe PPC service in the overlay network requires that IN subscribers have special numbersegment or access code so that the sorting of CDRs can be conducted at the billing centerbased on the following10486981048698The calling number segment or access code in the MOC CDRs from the originatingoffice and10486981048698The called number segment or access code in the MTC CDRs from the called officeHUAWEI CSOFTX3000CDR Description 5 CDR Control and SortingIssue 03 (2007-11-30) Huawei Technologies Proprietary 5-5

532 Sorting of Ordinary CDRsThe sorting of ordinary CDRs is subject to the charging policy of network operatorsFor example at the billing center CDRs can by sorted by types In case a CDR type isemergency call the CDR is deleted

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

53 CDR Sorting at Billing CenterThe billing center sorts the final CDR and discards CDRs that need not be charged CDRsorting includes the following types10486981048698IN CDR sorting10486981048698Ordinary CDR sorting

531 Sorting of IN CDRsIN CDR sorting is carried out in the following two IN modes10486981048698Target network10486981048698Overlay networkTarget Network ModeThe billing center can identify the IN CDRs according to the IN service identifier and usertypes The relevant value is in the IN service identifier of IN CDRs and the value is invalid inthe IN service identifier of ordinary CDRsOverlay Network ModeThe PPC service in the overlay network requires that IN subscribers have special numbersegment or access code so that the sorting of CDRs can be conducted at the billing centerbased on the following10486981048698The calling number segment or access code in the MOC CDRs from the originatingoffice and10486981048698The called number segment or access code in the MTC CDRs from the called officeHUAWEI CSOFTX3000CDR Description 5 CDR Control and SortingIssue 03 (2007-11-30) Huawei Technologies Proprietary 5-5

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

minus The GMSCSSP produces one transit CDRThe following are some remarks about CFW CDR10486981048698If a subscriber registered with CFU is the called party the CDR is generated at theCSOFTX3000 that requests the TLDN In the first two scenarios of the previousexamples the VMSC requests the TLDN and generates the CDR In the third scenariohowever the GMSCSSP requests the TLDN and generates the CDR10486981048698The CFW CDRs are produced at different places when two subscribers registered withCFNA and CFB are in the same location but are configured with different forwardingconditions The CDR for CFNA and CFB users is produced on the CSOFTX3000 thattriggers the forwarding usually the originating office or the gateway office The fill-outrules for these two types of CFW CDRs are the same as that of the CFU CDRs Only theservice feature indications are different10486981048698CFD is a combination of CFB and CFNA The prerequisites for trigging the CFD are thesame as those for trigging CFB and CFNA The only difference is that the ServiceFeature Indication in this scenario is CFDIn the previous examples calls are forwarded to PPC subscribers If the forwarded-to number is not aPPC subscriber number GMSCSSP is not involved

422 Examples of Producing Call Waiting CDRsCall Waiting (CW) is a supplementary service originated by the network When subscribersactivate the CW service they can receive a notice for another incoming call while holding thecurrent call In this case they can choose to accept refuse or ignore this incoming callIn this scenario MS-A and MS-B are in VMSCA and MS-B has the CW service activated1 MS-A calls MS-B and they are in conversation2 MS-C from another network calls MS-B and the CW service is activated3 MS-B holds the call with MS-A and starts conversation with MS-CHUAWEI CSOFTX3000CDR Description 4 Examples of CDR ProducingIssue 03 (2007-11-30) Huawei Technologies Proprietary 4-23Figure 4-27 shows the producing of the CDRsFigure 4-27 Call waitingGMSC TMSC VMSC MS-ABROAM TRANSIT MOCMTCMTCMS-CThe following describes the produced CDRs10486981048698The VMSC produces an MOC CDR to charge MS-A In the CDR the calling party is Aand the called party is B10486981048698The VMSC produces an MTC CDR to charge MS-B In the CDR the calling party is Aand the called party is B10486981048698The VMSC produces an MTC CDR to charge MS-B In the CDR the calling party is Cthe called party is B and the Service Feature Indication is CW10486981048698The GMSCSSP produces a roam CDR10486981048698The TMSC produces a transit CDR

423 Examples of Producing Call Transfer CDRsIf a subscriber registered with the Call Transfer (CT) service sets up two calls (incoming oroutgoing calls) this subscriber can connect these two remote parties through an ordinary callAfter the setup of connection this subscriber releases the call connection with those tworemote partiesAfter the CT service the charging rule and rate remain MOC CDRs and MTC CDRs areproduced for each connected partyIn this scenario MS-A and MS-B are in the same VMSC MS-A has the CT service registeredand activated MS-C is in another network

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs

52 Number Conversion for CDRsSometimes you may require conversion of the numbers in the CDRs such as changing the

calling number the called number the third party number or the called party MDN Incorrectconfiguration may cause unexpected loss to the network operator Therefore conduct dialingtest to the relevant number segment after you convert the numbers and ensure that all types ofnumbers in the CDR are correctly convertedUse the command ADD BLLMNG when you change the numbers in the CDRs
