1 Introduction to NETAN2000

NETAN2000 is a powerful and easy to use traffic measurement Analyzer, fully programmed with BORLAND C++. There is no need for any additional programs like MS EXCEL to run NETAN2000.

NETAN2000, the NETwork ANalyzer for SIEMENS MSC/VLR/HLR and SSNC/SGSN is the tool you need if you are:

* A network operator or service specialist who wants to be informed about the Grade Of Service of the network* A network operator or service specialist who wants to look for problems with the help of traffic measurement* A network operator who wants to detect traffic bottlenecks as soon as possible* A network operator who wants to make a traffic forecast, essential for demand-oriented expansion* A network operator who wants to be informed about the actual traffic model

All these tasks can be performed by using the integrated traffic measurement functions in a SIEMENS D900/1800 network element as well as in SSNC and GPRS elements. The various measurements can deliver more than 1200 different counters, which is of course a huge amount of information.To manage this information easily, to differ between important and unimportant counters and to set the different counters in a correct relation the NETAN2000 tool was developed.

NETAN2000 offers the following evaluations:

MSC/VLR/HLR:

Grade of Service: The 'Grade Of Service' (GOS) contains the most significant values, which indicate the performance and quality of a MSC/VLR. The GOS is based on the MSC traffic measurements RECMSC, RECVLR, RECCP.

Call Model: The ‚Traffic Model Evaluation' contains the most significant values, which are important for the capacity of a MSC/VLR or HLR. The 'Traffic Model Evaluation' is based on the SSS traffic measurements RECMSC, RECVLR, RECHLR, RECCP.

C7 Link Load: The CCS7 Link Load analysis calculates the load of each CCS7 link. The result shows the design specific usage of the CCNC with its allocated HW-units and the relevant load in Erlang. The ‚C7 Link Load Evaluation' is based on the SSS traffic measurements REC C7LLOAD together with the DISP C7LINK command.

Trunkgroup: The trunk group analysis can be separated in two blocks: Planning values: The planning values can be used for the dimensioning of the trunk groups. The Trunk

Group Analysis detects possible bottlenecks and resource problems on the trunk groups. 'Grade of Service' values: The 'Grade of Service' values show the success of the handled calls, e.g. the

answer rate, possible technical problems in own or other exchanges as well as possible database problems.

Cell Analysis: By analyzing the Cell Specific Traffic Measurement Data, possible existing problem areas can be detected by the cells' geographical location. If the radio side of the network is from a different supplier than SIEMENS, the MSC traffic measurement on a cell basis is a very fast and effective way, to get an overview on the performance of the radio subsystem.

Additionally the main results of the above mentioned evaluations could be stored in a database called 'Long Term Statistic'. With the 'Long Term Statistic' you will get an easy to use instrument, which allows observing the quality of the network over a long period. This is important to see figures like success rates, number of subscribers or CP load evolution.


SSNC: MP Load: The SSNC consists of several Main Processors (MP). A main processor can handle several software processes, such as packet processing, protocol handling, performance measurement and OA&M functions. Here the load of each MP is shown. The ‚MP load Evaluation' is based on the measurement CR MPLDME as well as some DISP commands.

C7 Link Load: The CCS7 Link Load analysis calculates the load of each CCS7 link. The result shows the design specific usage of the SSNC with its allocated HW-units (MP) and the relevant load in Erlang. The ‚C7 link load Evaluation' is based on the measurement CR SIGLME as well as some DISP commands.

GPRS:

MP load see SSNC

C7 Link Load: see SSNC

Grade of Service: The 'Grade Of Service' (GOS) contains the most significant values, which indicate the performance and quality of a SGSN. The GOS is based on the SGSN measurements CR SMEALL.


2 Basics

2.1 Installation

Hardware prerequisites: NETAN2000 runs on every Windows 32 bit operating system like WIN95 or higher. NETAN2000 needs about 4 Mbytes hard disc space and about 10 Mbytes additionally for the Borland database engine.

NETAN2000 is fully programmed in BORLAND C++ Version 5 and uses for the database functions the BORLAND database engine Version 5, which will also be installed on your PC during the installation progress.

NETAN2000 comes with an installation routine, which will guide you automatically through the whole installation progress. You have only to select the directory on your hard disc where you would like the tool to be installed.

To start the installation routine simply double click the SETUP.EXE file and follow the steps. Please read carefully the Licence agreement.

2.2 Starting traffic measurement jobs

Following measurements can be evaluated within NETAN2000:

MSC/VLR/HLR (with CCNC):REC MSC MSC traffic load and grade-of-service measurementREC VLR VLR traffic load and grade-of-service measurementREC HLR HLR traffic load REC INTCELL INTCREL internal cell related measurementREC CP Call Processor load measurementREC TGRP Trunk group measurementREC C7LLOAD CCS7 Link Load measurement

A measurement job is activated by an MML command in which the type of traffic measurement, the objects to be measured, the recording period, and the output device are specified. For NETAN2000 a continuous measurement job with output to day files on magnetic disc is used (so called daily files). Daily files contain only the data related to one measurement day. A day file is assigned to only one specific measurement job, i.e., only one traffic measurement type per file.Up to seven files can exist simultaneously for each job. If the user does not delete the file after it is evaluated, it is overwritten on the same day of the following week. Usually the measurement data is taken continuously but is processed only after input of an MML command. This means none of these measurements causes an additional CP load. The coordination processor (CP) main memory reads the data selected by the operator and outputs it to specified devices. This takes place every fifteen minutes during the active traffic measurement intervals.

MML commands:

REC MSC: REC MSC: UNIT=MDD-DAILY; File: MT.USMM.xxyREC VLR: REC VLR: UNIT=MDD-DAILY; File: MT.USVM.xxyREC HLR: REC HLR: UNIT=MDD-DAILY; File: MT.USHM.xxyREC INTCELL: REC INTCELL: UNIT=MDD-DAILY, TYPE=INTCREL; File: MT.USIM.xxyREC CP: REC CP: UNIT=MDD-DAILY; (def. 3 min.) File: TS.CPXX.xxy REC TGRP: REC TGRP: UNIT=MDD-DAILY, TGRP = X; File: TS.TGRP.xxyREC C7LLOAD: REC C7LLOAD: UNIT=MDD-DAILY, LSNAM=X; File: TS.C7LL.xxy

2.3 Transfer of traffic measurement files

The transfer of daily files is only possible after the day concerned or at the end of a measurement job.The traffic measurement raw files have to be transferred from the magnetic disc to the PC where NETAN is installed.Therefore different possibilities can be used. Following some of these procedures will be described in detail:

2.3.1 Basic Craft Terminal BCT

On the BCT you have to start the 'openFT' function. In the 'Transfer file' menu select the following parameter: File Type = Text.

In the BCT you can use any available file compressor like WINZIP, WINRAR or ARJ.


2.3.2 Operation Maintenance Center OMC

On the OMCS you have first to open an EMML session. Then select the GUI sub window 'Filetransfer'. A mask will pop up which looks like this:

In this window you have to specify the following parameters: Selection: OMC or OMT depending to where the file is to be transferredLOCFIL: file name on local HD (including path)REMFILE: filename on MSCTRDIR: GET (if file is to be transferred to the OMC-S)PRONAM: logical name of MSCUSRINF: user log-in SESPSW: user passwordWRMOD: OVWRCOPMOD: CHAR

This will transfer the traffic measurement files from the MSC to a directory on your local OMT HD (to be specified in LOCFIL).

To transfer the data from the OMT to a PC- insert floppy without write protection into floppy drive of OMT- on a UNIX shell enter 'volcheck' - enter 'cp "name" /floppy/floppy0' ("name": name of traffic file on OMT HD including path- enter 'eject' to remove the floppy from the HD

In case the files are too big to be copied to a floppy, you can use the 'compress' command on a UNIX shell: compress usmmsc1If 'compress' is used the files which are transferred must not have any extension: (e.g. 'usmmsc1' rather than 'usmmsc1.txt')


2.3.3 Switch Commander SCFor getting data of MP, SSNC,and GPRS measurement the PDC (performance data collector, see description A50016-D521-B100-2-7620) must be installed. Here the data are available and can be copied to disc as they are; if there are many files, zipping is recommended.

For the copy of the DISP commands please make sure to use the ASCII mode, not UNICODE for creating the file!


No

Yes

2.3.4 Examples:

You can easily check the correct format of the file after transferring to your PC, the file must be readable in a normal texteditor and must not contain any unreadable characters.

2.4 Quickstart

Copy the measurement files of the NE's you want to analyze into a directory on your PC.

Choose 'START EVALUATION' from the 'EVALUATION' menu. The 'Availability Check' window will appear.

Select the 'Source Directory' where the measurement files are stored. Select a 'Result Directory' where you want to store the result files. Alternatively, the box 'Same as Source Directory' can be ticked which automatically sets the result

directory the same as the source directory. Paths in 'Source Directory' and 'Result Directory' can contain a maximum of 37 characters.

Press The availability check will be performed. This means all files in the specified 'Source Directory' will be scanned for the following information:- Measurement file, which can be used for an evaluation?- Date and NE name of the measurement file- All necessary measurement files included?


After finishing the availability check the window will change and present all possible evaluations:

Here you will get a choice of all possible evaluations found in the specified directory. You can now select all evaluations, all evaluations of a common type or only a single evaluation.

When you have chosen the evaluations you want to perform click on the button.

In the 'EVALUATION WINDOW' you can observe the progress of the current evaluations. After finishing the evaluation you can close the window and open a result file by choosing 'OPEN RESULT FILE' from the 'FILE' menu in the main window.


2.5 Availability Check

The availability check is the first program part, which runs immediately after starting an evaluation.

The main tasks of AV check are:

- Checking a specified directory (optional with its subdirectories) on availability of traffic measurement files which can be used for evaluations- Checking the contents of the files for MSCNAME, DATE and TYPE of traffic measurement- Checking the availability of a MLOG file with DISPC7LINK (used for CCS7 evaluation)- Checking the traffic measurement files on completeness of all measurement intervals

When AV check is finished the results will be shown in the lower part of the window:


With these buttons you can select all possible evaluations of one type (e.g. Grade of Service)

With this 2 butttons you can select and deselect all possible evaluations (all NE's, all dates)Selecting a MSC and

a Date will present the possible evaluations on the right side

2.6 Cyclic file conversion

In software version SR8 a new possibility to record measurement files in a cyclic file format was introduced. The advantage of this type is that the user can transfer the result file from a running measurement at any time.

As these files can contain data from one quarter up to app. 3 days a new routine had to be implemented in NETAN2000 to produce readable result files out of this data.

Explanation how it works:

First the 'Availability Check' checks the header of the measurement files. A cyclic file is identified within the header by the filename 'MF.xxxx.CYy'.

01931G018 15 MSC04 MF.USVM.CY1 00-11-1401:00 630123180 3570 4675 6742 39019 0 930 39 25

Example of a cyclic file

A special routine within the 'Availability Check' converts now all detected cyclic files into pseudo daily files. This means the contents of the cyclic files will be rearranged and copied into files, which correspond to the format of the known daily files.

The new files will become following naming construction:

- MSC0400-11-14USVM.craw (includes MSC name, data, measurement type).

During the 'Availability Check' with cyclic files following box will appear:

If you click on 'JA' or 'YES' the original raw cyclic files be deleted from the hard disc and only the created CRAW files still exist.

After the CRAW files are prepared the following procedure is the same as with original daily files.

Even if the CRAW files do not contain the complete data of a full day e.g. only one hour an evaluation will be possible if there are the same intervals available in the needed measurements (e.g. for GOS evaluation RECCP, RECMSC and RECVLR).


2.7 'Pseudo cyclic' file conversion

The so-called 'pseudo cyclic' file format is used in some projects. It works in that way that the measurement is started as daily but with OMC scripts the measurements can be stopped after 15 minutes transferred to the OMC and started again.This means that the contents look the same like for cyclic files but the header is different.For this files a new function is implemented.

If you want to translate such files you have to select the function 'ALL AS CYCLIC' before you start the AV check.

During the AV check following decision box appears:

Here you have to select 'YES' or 'JA' which means that the original files will be deleted and only the combined CRAW files will exist in the directory.

After the AV checks you can select as usual the evaluation types you want to perform.


2.8 Raw file conversion

The traffic measurement data generated by the MSC is kept on the MDD. The format of the files is an MSC internal format and cannot directly be interpreted by some common PC-software (e.g. EXCEL).

In order to overcome those weaknesses, a conversion routine is part of NETAN2000. This routine serves as an interface between the MSC's daily traffic measurement files (also referred to as 'source files’) and the so-called 'traffic measurement result files'. NETAN2000 can automatically detect the type of traffic measurement and converts the file from its MSC-internal format to a uniform text format.

Even for different traffic measurement types, the format of the result file has the same and a very simple structure. As they consist of text only, the result files can easily be imported into EXCEL sheets or word processing software.

2.9.1 Printing

With the Printing Options you can arrange the position of the result files within the printed pages. The distance to the margins can be selected and also the distance to the text charts. This has to be done for the different result files separately.

Attention: An error message will occur after closing the Options window if the line margin is equal or bigger than one of the text margins.

Example:

You have also the possibility to select your own Footer text for the printouts.

The header will be added automatically by the program using NE NAME, MEASUREMENT DATE, APS RELEASE on the left side and TYPE OF EVALUATION and EVALUATION DATE on the right side.Additionally to the normal print option in GOS there is also the possibility to select 'print all GOS' in the file menu. This prints all sheets at once.


2.9.2 Clearing the databaseIn order to start a new set of evaluations, the old database files have to be removed. This can be done by clicking Clear DB in the 'Tools' menu. If not the open result file process uses the existing temporary DB files.

2.9.3 Evaluation

If the checkbox 'Restrict Trunk Groups' is marked, some restrictions on displaying trunkgroups are set.

Attention: This restriction is only valid during the evaluation of a trunkgroup file. It has no influence on opening already existing trunkgroup result files.

The restrictions are:

Trunkgroups with no call attempts but showing low traffic volume are not displayed (signalling trunk groups)

Trunkgroups with call attempts but no traffic are not displayed

2.13Hints and Tips

- When I zoom into a chart, how can I come back to the full view? By drawing a rectangle with the mouse on the chart you can zoom into the timeline. Drawing a rectangle

by starting in the chart and ending outside the left border will change back to the 24-hour chart.

- Is it possible to sort a result table within the TGRP or CELL evaluation? Yes, it is. By clicking on the header of a column the table will be sorted in ascending order to the values

in the column. A second click on the same column sorts the table descending.

- If I have lots of measurement files from different network elements, how can I find out which measurements can be evaluated? NETAN2000 automatically reads the headers of all files in the 'source directory' and checks which files

can be used for evaluation. If it's necessary to have more than on file for a measurement (e.g. for GOS or Traffic model), NETAN2000 will automatically scan through those files and check for their availability.

2.13.1 Explanation of the different DEF, STAT, COUNTER and INI files

The NETAN 2000 tool works with different definition files. These files are simple text files, which are used to define externally different things like formulas, counters....

Please notice: Manipulating the DEF, STAT, COUNTER or INI files in an incorrect way may cause system crashes in NETAN 2000. All manipulations will lead to the loss of any kind of warranty.

Explanation of the different files:

- BUSY.DEFContains the formulas to calculate the busy hour/quarter for the GOS, TM, TGRP, CELL and CCS7 evaluation.

- MLOG.DEFDefines the position of the used information in the DISPC7LINK displays

- RESTRICT.DEFDefinition of trunkgroups with unnormal behaviour

- COUNTER.xxxOne file exists for each APS version.Used for the translation of the measurement files.Contains for every counter measurement type, byte position, field length, counter name- STATxxx.DEFDefines the formulas used in the different evaluations


- NETAN2000.INIThe main initialization file of NETAN2000 contains:

Relation between the Version number in the measurement file and the APS version Relation between APS version and used COUNTER.XXX file The OPTIONS settings The rates displayed in the LTS tool

- LTSstat.DEFDefines the rates used in the LTS file, which are extracted from the NETAN result files.Each Line contains the evaluation type, rate name and the unit

Please notice: If you want to add new rates add them at the end of the evaluation section only. Otherwise you cannot use your old LTS files.

2.14Updates / new features

3.2.1.1 GOS - Grade Of Service

3.2.1.1.1 Prerequisites

The Grade Of Service evaluation requires following measurements:- REC CP Call Processing Load- REC MSC MSC specific measurement- REC VLR VLR specific measurement

3.2.1.1.2 Basics

What is Grade Of Service:

Requests and attempts for certain services and system functions are offered to or generated by the PLMN and its units according to the model above and used for obtaining the data for GRADE OF SERVICE measurement. These requests and attempts can be generated by either the mobile subscriber (e.g. by dialling a number) or by the system (e.g. by starting a handover).

The requests and attempts bring about system activities being are carried out with a certain grade of service. Some attempts are completed successfully whereas others are terminated unsuccessfully (loss, abandonment or rejection).Unsuccessful attempts can be offered again or automatically repeated by the system. Successfully completed actions can lead to further activities.


Requests Attempts

Behaviour of mobile subscriber

Unsuccessfully terminated

Successfully completed

System behaviour

Reasons related to user/network

A distinction can be made between the following groups of unsuccessfully terminated attempts: Behaviour of the mobile subscriber (e.g. incorrect dialling, replacing of the handset during call set up...) System behaviour (e.g. lack of resources, overload...) Reasons related to the user or the network (e.g. certain features are blocked, subscriber blocked by the

operator...).

Certain errors within the grade of service measurement jobs are derived from the error causes within the protocols used (e.g. MAP...). Two release events can be distinguished: The release event detected by the call processing software in the LTG (GP) is sent as a "reason for call

failure" (RCF) in the release message from the LTG's (A-side and B-side) to the CP. The call is then prematurely terminated.

The release event detected by the call processing software in the CP is sent as a "reason for call termination " (RCT) in a command (e.g. TERMINATE) to the LTG's. The call is then prematurely terminated.

The MSC basic traffic measurement part includes data concerning the call set up for speech and data calls. Within this MSC basic traffic measurement part, most of the counters can be differentiated by several traffic types. The traffic types provided in the MSC contain information on the origin and destination of the call.

The observed MSC detects whether the call to be handled either has been originated in its own area, or transmitted by another exchange. From this point of view one can distinguish: Mobile originating traffic (MORTR): All traffic being initiated by a mobile subscriber in the area of the

observed MSC, whatever the destination will be. Mobile incoming traffic (MICTR): Mobile traffic that has been directed to the observed MSC by another

exchange.

Next an interrogation process is started as the result of digit analyzing. Once the result of the interrogation has been established through digit translation, the observed MSC knows where to find the call destination, changing the original traffic type into one of the following types: Mobile terminating traffic (MTER): This applies to the traffic towards each mobile station in the area of

the observed MSC Mobile originating outgoing traffic to a mobile party who is subscribed in the home PLMN

(MOUT_PLMN), wherever he is actually roaming. Mobile originating outgoing traffic to a party from the PSTN or another PLMN (MOUT_NOT_PLMN). Mobile transit traffic (MTRANS): Traffic that has neither been initiated nor terminated at the observed

MS.

3.2.1.1.3 Evaluation

MOUT Table (Mobile outgoing):

The diagrams are divided into MOC’s for MOUT_PLMN and MOUT_NOT_PLMN. For each case, the ‘answer’, ‘no answer’ and ‘B-busy’ rates are shown. These three values are combined in ‘MOC success rate’. The rest which is covered with ‘Others’ indicates potential problems.Additionally, ‘average call duration’ and ‘Fax/Data’ success rates are displayed.

MTER Table (mobile terminated):

For MTC’s the ‘answer’, ‘no answer’ ‘B-busy’ and ‘Call Forwarding’ rate are printed. These four values are combined in ‘MTC success rate’. The rest which is covered with ‘Others’ indicates potential problems.Additionally, ‘average call duration’ and ‘Fax/Data’ success rates are displayed.


MOBILE ORIGINATED TRAFFIC analysis table:

For MORTR traffic the calls are split up in ‘MMC to own MSC’, ‘MMC MOUT_PLMN’, ‘MOC MOUT_NOT_PLMN, ‘NO TCH Allocation BSC’, ‘No TCH request generated’ and ‘Call forwarding MORTR’. The rest ‘Others’ are indicating problems.

Handover Analysis Table:

Handover success rates are detailed in ‘intra MSC success rate’, ‘inter MSC A success rate’, ‘inter MSC B success rate’, ‘HO not allowed’ and ‘HO fail’. Depending on the geographic coverage of the radio network, the VLR area measured might not have common borders with other VLR's. In this case, the ‘inter MSC success rates’ might be poor or even zero.

LOCATION UPDATE and PAGING table:


Location Updates are detailed in ‘Location update success Rate’ and ‘Others’. ‘Others’ can be interpreted as location update failures.Paging is split up in ‘successful paging’, ‘paging time out’ and ‘Others’. ‘Others’ covers all cases, which are not contained in ‘successful paging’ and ‘paging timeout’.

SHORT MESSAGE SERVICE table:

For SMS the statistics covers ‘successful SMS Attempts’ and ‘unsuccessful SMS Attempts’ (‘Absent MS’ and ‘Delivery failure’).

MSC/VLR LOAD ANALYSIS table:


SUM of CARRIED TRAFFIC (mERL)CP - usage Load A (CALLP) % = ——————————————————— * 100

Xn


User Defined table:

This table allows the user to create 20 different rates with formulas defined manually.

To define formulas open the file STAT.DEF of STAT_SR8.DEF (from the NETAN 2000 directory) with a text editor like Notepad. Search for the following text string: 'USER DEFINED FORMULAS DEFINITION'.

Here you will find the definition of the formulas:

// *** USER DEFINED FORMULAS DEFINITION ***

Example: Change '1' to '(UNS_MS_BUSY_MTER / CALL_ATTS_MTER) * 100'

Attention: Be careful while changing the 'Definition Files'. Formulas with wrong syntax may lead to program crashes during the evaluation.


3.2.1.2 Traffic Model


The traffic model evaluation requires the RECMSC, RECVLR, RECCP, RECHLR and RECSCTC data files. As a result, a set of parameters will be calculated which unequivocally describe the capacity requirements of a network in order to make most efficient use of a network without causing overload or congestion.These parameters are:

- Number of VLR subscribers- BHCA total/SUB- BHCA mobile/SUB- Interrogation for MTC/SUB- Interrogation for Transit Calls /SUB- MMC to other MSC /SUB- internal MMC (MIC)/SUB- TRANSIT-CA/SUB- HandOver/SUB

- INTRA-BSS-HO/SUB; BSC controlled- INTRA-MSC-HO/SUB; MSC controlled- MSC-MSC-HO- LUP/SUB with/without HLR Interworking - SMS /SUB for MOC/MTC- Mean Holding Time [sec]- Mean Call Duration [sec] for MOC/MTC- CP loadetc....

3.2.1.2.2 Basics

The traffic model is crucial to the dimensioning of the measured exchange as well as for the whole network. Since the hardware/software configuration of each exchange is based on a set of pre-defined Traffic Model parameters, these parameters have to be permanently monitored. If the call behaviour in the network is changing, the traffic model parameters will change as well and the dimensioning of the exchanges and the trunks have to be adjusted.



The traffic model gives a complete set of traffic parameters that are necessary for the appropriate planning of a mobile network.As an additional feature, the result parameters can be saved as text ('save to text' in File Menu). This text format can then directly be imported into analysis tools for radio planning.


3.2.1.3 Trunk Group Evaluation


The Trunk Group Evaluation requires only the REC TGRP measurement as input file. The measurement can be started for all trunkgroups (TGRP=X) or only for selected trunkgroups.If there is more than one trunkgroup file from the same NE and Date NETAN2000 will combine the results in one result file.

3.2.1.3.2 Basics

Trunkgroup related traffic measurement (REC TGRP) jobs register data for the following positions: Traffic load and seizure related data (e.g. number of seizures, traffic volume) Resource and structure related data (e.g. number of lines, number of blocked lines) Data related to grade of service (number of successful calls).

The results of trunk group measurement are the counts recorded by event counters, holding time counters and overload counters.

By clicking the header cell of a certain parameter, the TGRP data can be rearranged in descending order. A double click on the header arranges the TGRP data in descending order.The TGRP evaluation program contains all call success relevant data split up for each TGRP. The following table gives an overview over all relevant parameters:

Not all of the created trunkgroups might appear in the result file, please refer to chapter 2.9.3, evaluations.


By clicking the header cell of a certain parameter, the TGRP data can be rearranged in descending order. A double click on the header arranges the TGRP data in descending order. The TGRP evaluation program contains all call success relevant data split up for each TGRP.


3.2.1.4 Cell Evaluation


The CELL Evaluation requires only the REC INTCELL, DTYPE INTCRELL measurement as input file. The measurement should be started for all cells.

3.2.1.4.2 Basics

Cell related measurements evaluate all important cell quality parameters such as:

- Assignment failure Possible reasons:

Lack of air interfacesInterferenceInstallation and commissioning faultsHW problems

- Setup Failure:Possible reasons:

Lack of air interfacesInterferenceInstallation and commissioning faultsHW problems

- Dropped calls:Possible reasons:

Hardware problemsInterferencePoor coverage

- Handover failure:Possible reasons:Poor coverageInterferenceLack of air interfaces

This evaluation gives an accurate and comprehensive quality overview over all cells. This is particularly important since the radio part is most critical to the performance of a radio network. According to the above stated parameters, certain reasons for problems can be determined and solutions be worked out.The cell data can also be sorted in ascending or descending order: by clicking the corresponding cell header once, the table will be rearranged in descending order, a double click will sort them in descending order.

Changing the value in 'Show Call Attempts' allows filtering out all cells that don't reach the defined value of call attempts.




3.2.1.5 CCS7 Evaluation (for CCNC)


The CCS7 Evaluation requires the REC C7LLOAD measurement as input file. The measurement should be started for all #7 Links.Additionally a MLOG Display with the result of the command 'DISPC7LINK: LINKNO=X;' is required. From SR4 on the relation between LINKNO and SILTNO can only be found by using the MML command DISPC7LINK:SILTNO = X; the relation is necessary to get the distribution of C7 Links within the CCNC hardware structure.

Attention: If new links were added or old links removed the measurement has to be stopped and started again. Otherwise the changes will not appear in the measurement.

3.2.1.5.2 Basics

Why CCNC Load Balancing

The CCS7 signalling links connect signalling points in a communication network. The signalling points and the signalling links form an independent signalling network that is overlaid over the circuit network.In a D900 entity all CCS7 signalling links are connected to the CCNC.The CCNC handles the message exchange between various nodes for controlling and monitoring connections as well as for operating the signalling network.In a constantly growing GSM-network the load on the signalling links will change permanently. To account for this changes and due to the design specific construction of the CCNC certain configuration rules must be considered.The load dimensioning should be done on a regular basis, depending on the activity changes in the #7 network.SIEMENS recommends a monthly evaluation if the activities in the network are normal.

Balancing and Dimensioning Rules

Recommended load values for CCNC Units in Erl.:

C7-Link Load should not exceed the value of 0.2 Erl. per link.The total load of a SIPA should not be higher than 1.6 Erl. This value will only be achieved if all four SILTC's are connected and carry an even balanced load. The above given recommendations should be applied in the complete D900 Nr7- network.

SILTD: 0.2 Erl. The direction with higher load should be considered (RX or TX)SILTC: 0.4 to 0.8 Erl. Depending on how many SILTC's are connected to a SIPASIPA: 1.4 to 1.6 Erl. Best SIPA performance is if all 4 SILTC's are connected and allocated with

equal load



Example of the printed or ‚saved to bitmap’ file:


For the CCS7 evaluation the traffic measurement and the DISPC7LINK Mlog output of the exchange has to be collected. The CCNC evaluation result displays the load per SILTD as well as well as per SIPA (sheet 'per SIPA'). Additionally, the total load of the CCNC is displayed.The 'per link set' sheet displays the link load according to all links in a C7LSET.

The distribution sheet details the SILT-C load in a bar diagram. This allows one to monitor the load distribution and draw conclusions as to how to balance the load.


Per Link Set Table:

This table allows checking the current load sharing within all links of the selected linkset.


3.2.2 SSNC / GPRSThe formulas that are used in SSNC/GPRS evaluation you find in the documents

MP Load Measurements formulas.doc SSNC formulas.doc GPRS formulas GR20.doc

Additionaly to D900 evaluations you will find the ‚quarterly period’ button for time selection. That means that you are able to select not only an hour (e.g. busy hour) but also any quarter of the day (e.g. busy quarter).

3.2.2.1 MP Load


CR MPLDME Create MP Load MeasurementDISP MP display of the types of MP

The MP evaluation needs – besides the measurement file- the DISP MP command file to indicate the type of MP. This is important for a calculation of specific load.

3.2.2.1.2 Evaluation:

MP evaluation

The SSNC/SGSN consists of several Main Processors (MP). A main processor can handle several software processes, such as packet processing, protocol handling, performance measurement and OA&M functions. Here the load of each MP is shown. The ‚MP load Evaluation' is based on the measurement CR MPLDME as well as some DISP commands. With the aid of the DISP files we can show the type of the MP. Each process on the MP has a so-called load budget, which states a guaranteed time assignment.


Example: The MP1, Type SA, has a budget for OAM processes of 730mErl, in the picture above it used 317 mErl; so it used the „OAM capacity“ to ~43%. The total load was 353 mErl (max 999mErl), i.e. the total load during busy quarter was ~35%.

With the button MP->Text the load of all MP’s during the specified time unit is stored as a text file on disk.

CR MPLDME Create MP Load MeasurementCR SIGLME Create Signaling Link Meas.(CR SPME Create SCCP Measurements)

DISP SIGDL assignment internal name MPDISP SIGLINK assignment internal neme linkset name

Besides the measurement NETAN processes the DISP SIGDL and DISP SIGLINK command files. They serve to indicate the relation between linkset name (as the operator knows them) and the internal name (given by the system).


General remark: SSNC description shows that the SSNC can handle a permanent load of 0.4 mErl. This is internal handling and has nothing to do with the ITU recommendation of 0.2 mErl maximum load. Thus a provider may apply the 0.4 mErl limit internally in his network if the counterpart is a SSNC as well; if the traffic is going out of the network he should restrict to the ITU recommendation (<0.2mErl. load per link).


MTP measurement for MP

MTP measurement shows linkinformation HW-oriented (per MP), additionally the total load per MP and SSNC.Bytes: MSU*6 + (rec/trans)SIFSIOLoad (mErl): Bytes / 8 / interval(sec)Total MP: Sum of values of individual links per MPTotal SSNC: Sum of values of all links of all MP’s

3.3 Detailed Evaluation / Time Line Charts

If you want to see a daily chart for a calculated value or any counter in the measurement, this is the function you need. Also you can put different counters or statistics in relation and observe the behaviour over 24 hours.You get also the possibility to look for counters that are not in the predefined formulas.

For trouble shooting this is the functionality you always have been looking for. It will become an easy task to look for overload problems or something similar.

How does it work?

With a double-click on any position within the chart window the 'Selection Window' will appear. Here you can add the statistics or counters to the 'Showed Values' window. When finished click on the OK button and the chart will be presented.


Click on this button to open that window

By drawing a rectangle with the mouse on the chart you can zoom into the timeline. Drawing a rectangle by starting in the chart and ending outside the left border will change back to the 24-hour chart.

4.1 LTS Program

This option gives one the possibility to evaluate performances of exchanges over a long period of time. The program reads the measurement parameters for the busy hour of each day into a long-term table and displays counters over time.

Following result files can be added to the LTS program: Grade Of Service results Traffic Model results CCNC evaluation results TGRP evaluation results

It is possible to add more than one result file in one step. When adding a result file you will be asked for a project name. This allows keeping the results of different projects in one LTS file.

The LTS file can be saved. It is possible to add a LTS file (e.g. from another project) to an existing LTS file.The LTS file can be filtered and sorted due to the users requirements.The LTS file can be imported into e.g. MS EXCEL for post processing tasks.

Example:


By double click on the right part of the main window a new window appears there you can select a list of rates that should be shown. The selected rates will be saved and appear also the next time you start the LTS program.
