Parameter Description

This parameter indicates the index number of a cell.

A string of 1 to 32 characters A string of 32 characters

It is min Rx-Level for Decoding of RACH

Used for Reducing Network Interference & Increasing Stand-By time of MS.

Cell Reselection Penalty Time to ensure the avoid Ping-Pong Cell Reselection

Cell Reselect Temporary Offset (TO) indicates the temporary correction of C2.This parameter functions only before the penalty time of cell reselection expires

Used with Cell-BAR-Access to Priopritize a Cell for Cell Selection/Reselection

This Indicates whether a Cell Access is Barred or not. Together with CBQ it is used for determinig Priority of Cells.

Whether the BSC is based on different modulating modes to select different working voltage.

Whether the BSC allows the dynamic shutdown of TRX power amplifier

This parameter determines the actual coverage area of a cell. When the BTS receives a CHANNEL REQUEST message or a HANDOVER ACCESS message, it compares the TA with the value of this parameter to determine whether channel assignment or handover is performed in this cell.

This parameter indicates whether downlink DTX is used in a cell.This parameter, which consists of eight bits (from the most significant bit to the least significant bit), indicates whether the A5/0, A5/1, A5/2...A5/7 encryption

algorithm is supported respectively. 1: It indicates that the BSS supports the encryption algorithm. 0: It indicates that the BSS does not support the encryption algorithm

This parameter indicates whether the adjustment of BTS power is allowed.

This parameter indicates whether the adjustment of MS power is allowed.

This parameter indicates the whether the directed retry on the TCH is allowed. If this parameter is set to Yes, the handover procedure is used and the MS is handed over to the neighboring cell. Direct retry is an emergency measure for abnormal peak traffic in the local wireless network. It is not a primary method of clearing traffic

congestion. If direct retry is preformed frequently in a local network, you must adjust the sector carrier configuration of the BTS and the network layout.

Yes: It indicates that the TCH is immediately assigned when the SDCCH has no available resource during the processing of access request. No: It indicates that only the SDCCH can be assigned.

If you make a cal & after Successfully SDCCH Sezure,TCH Assignment is failed then this will decide whethere to Retry for TCH assignment,on same SDCCH,or Not.Commonely User does not wait for so much long time & manualy cancells the call,so that`s why we don`t use this parameter

Additional Cell Reselectiom Param Indication:If ACS=0,Invalid in SySTEM INFO=3,but works in SYSTEM INFO=4 to tell SYTEM INFO 4.IF ACS=1,tells it means that the MS should obtain PI and other parameters for calculating C2 from other bytes of system information 7 and 8.

If this parameter is reasonably configured, the number of handovers can be reduced and a better cell can be assigned to.When PT is set to 31, it becomes more difficult for an MS to access a cell when CRO increases

Cell Reselection Parameter:Indicates whether to perform C2-Based Cell reselection.When PI=1 MS will calculate C2 from SYSTEM INFO and perform Cell Reselection.If PI=0 then C1=C2,Cell-Reselection will be based on C1

CELL_RESELECT_HYSTERESIS,As MS does not responds to Paging messages during Location Update,too much Cell-Selection will lead to Connection drop.If it too Low,Frequent Cell-Rselection will Occur causing Load on Signaling.Too High value can cause MS t o CAMP o Older cell even when LAC Area is Changed"Forced Periodic Location Update".T3212 is used for Forced Location Update of Every mobile in Cell-Coverage Area.Unit id 6 minutes. If any mobile failed to respond

to Paging message for a long time it will be considered as "Off-Line",and if this mobile cell-Reselection,T3212 will Reset & Network still Can`t find Location of MS,So it will be "OFF-Line" for a Long time.

Paging MutiFrame period:Defines Period for sending PAGING REQUEST message for to same Paging-Subgroup,the number of paging sub-channels on a specific paging channel.

.When MFR increases, the number of paging sub-channels increases, thus reducing the number of subscribers served by each paging sub-channel and prolonging the average work time of the MS battery.Number of CCCH Blocks used for Access Grant Channel remaining are used for Paging channels.In each downlink non-combined SDCCH 51 frames multi-frame there

are 9 different CCCH blocks and in the combined BCCH/SDCCH there are 3 different blocksNetwork Colour Code that are Permitted,Sent in System Information type 2&6,This parameter can be used to make MS 's measurements on some adjacent cells

optionally.Cells with NCC ranging in NCC permitted range will MS report Measurement Reports

It indicates the number of timeslots in an interval when an MS sends continuously multiple channel requests.Used to Reduce Collision on RACH & to Increase Efficiency of RACH.

IMSI Attach?detach allowed:Detach,This is the Last message that MS Sends when it is Powered-Off,If set to No then System will have to wait for T3212 for considering MS to be "OFF-Line".IMSI Attach is First message generated by MS to Inform Network its Presence

whether the timeslot is busy and affects the normal access of the MS. The MS access is allowed only when the level of the MS random access burst is greater than the RACH Busy Threshold.

In the BTS24 version, this parameter indicates the level threshold of the MS random access for the system to determine the RACH busy state. When the receive level of the random access burst timeslot is greater than the threshold, the BTS considers that the timeslot is busy. This parameter also indicates whether the MS access is

allowed. The MS access is allowed only when access level (including random access and handover access) is greater than the threshold.

0-63 with 0 indicating -110 dBm and 63 indicating -47 dBm In the BTS2X version (BTS24 not included), this parameter indicates the level threshold for the system to determine MS random access.When the receive level of a random access burst timeslot of the RACH is greater than this threshold, the BTS

considers that the timeslot is busy. This parameter must be set based on the actual sensitivity of the BTS and the lowest access level of the MS to ensure the uplink and downlink balance. This parameter also affects handover access of RACH BURST during asynchronous handover. For the BTS3X series and double-transceiver BTSs,

this parameter does not affect MS access but affects the report of CCCH_LOAD_IND. If the level received by the BCCH at the network side is greater than the RACH Busy Threshold, the CCCH_LOAD_IND is counted once whether the decoding is successful. The RACH whose level is lower than the RACH Busy Threshold and whose decoding is successful is also counted. The measurement period is the RACH mean load timeslot. If the value of this parameter is too small, the BTS easily considers

that the RACH timeslot is busy and reports overload messages to the BSC. If the value is too high, the BTS cannot determine the state of the RACH timeslot correctly. In the BTS24 version, if this parameter is used to judge busy timeslot, its setting is consistent that in the BTS30. If this parameter is the level threshold for valid random

access, its setting is consistent with that in the BTS20. The setting of this parameter for the BTS312, BTS3001C, BTS3001C+, BTS3002C and the double-transceiver BTSs is the same as that in the BTS30.

Informs the Network about UPLINK Connection Status.Every time BTS successfully decodes Measurement Report sent by MS,Counter for determining Radio Link Path is Incremented.But if fails then decrements by 1 untill 0 then BTS ends Radio Connection & sends Connection Failure Indication to BSCWhen BTS sends physical information to the MS, the BTS starts the timer T3105.If the timer T3105 times out before receive the SAMB frame from MS, BTS re-sends

physical information to MS and restarts the timer T3105. The maximum times for re-sending physical information is Ny1.The physical information is sent through FACCH, which is sent every four TDMA frames and takes 18 ms. If the value of T3105 is smaller than or equal to 18 ms, then BTS should re-send the physical

information to the MS when the timer T3105 times out for the first time.This timeout is meaningless if the physical information sent at the previous time is not sent on the FACCH because the time is shorter than a FACCH period.Considering the previous factors, 20 ms is the reasonable minimum value for this parameter. At present,

the default value of this parameter is 70 ms.

During asynchronous handover, the MS constantly sends handover access bursts to the BTS. Usually, the Timer T3124 lasts 320 ms. Upon detecting the bursts, the BTS returns physical information to the MS through the main DCCH/FACCH and sends the MSG_ABIS_HO_DETECT message to the BSC. Meanwhile, the timer T3105

starts.The physical information containing information on different physical layers guarantees correct MS access. If the timer T3105 expires before the BTS receives the SAMB frame from the MS, the BTS re-sends the physical information to the MS.

If the number of resending times exceeds this parameter (Ny1) and the BTS has receive no correct SAMB frame, the BTS sends the BSC a connection failure message, which also indicates handover failure.

This parameter indicates the period during which penalty is performed on the neighboring cells of the fast moving MS.During this period, penalty on the neighboring cells (on only the other three layers except the umbrella layer) of fast moving MS is valid.

This parameter indicates the penalty given to the level in a neighboring cell when an MS is moving fast.Only the cells in the umbrella layer can give penalty to the cells in other three layers.

This parameter indicates the timer that starts when the threshold of maximum consecutive intra-cell handovers is reached.Intra-cell handovers is allowed only when the timer expiresThis parameter indicates the maximum number of consecutive intra-cell handovers allowed.If the interval of two continuous intra-cell handovers is less than a

specified threshold, the two handovers are regarded as consecutive handovers.

Intra-cell handover is forbidden if the number of consecutive handovers exceeds this threshold.This parameter indicates the threshold for judging whether an MS moves fast across a cell.The threshold is obtained based on the cell radius and specified velocity.

If the time for crossing a cell is lower than this threshold, the MS is regarded as moving fast.

Suppose that the actual number of the micro cells that the MS fast crosses is N.According to the P/N rule,when the MS fast crosses N ones among the P micro cells, a fast moving handover is triggered by the BSC when this parameter satisfies the required conditions.

During the hierarchical load switchover, the load switchover band starts from Edge HO DL RX_LEV Threshold and a Load HO Step Level is added to the upper threshold of the load switchover band every one Load HO Step Period. In this way, the BSC conducts switchover level by level. Finally, all the calls with the receiving level of the current serving cell ranging from Edge HO DL RX_LEV Threshold to Edge HO DL RX_LEV Threshold + Load HO Bandwidth are switched over. The value of Load HO Step

Level must be smaller than the value of Load HO Bandwidth.If a cell load is not smaller than Load HO Threshold, all the calls with this cell as the serving cell send switchover requests simultaneously. As a result, the system load

soars.In serious situations, the congestion may occur to this cell, thus leading to call drop. To avoid call drop, the BSC uses the hierarchical load switchover algorithm to control the number of users who experience switchover at a certain level.

The setting of this parameter is relevant with Edge HO DL RX_LEV Threshold.A user is allowed to initiate load switchover only when the receiving level of the user's current serving cell is within the range from Edge HO DL RX_LEV Threshold to Edge HO DL RX_LEV Threshold + Load HO Bandwidth.

When the load handover is switched on, it is recommended that the Load HO Threshold is set to 85.The cell load refers to TCH usage.

the switchover threshold.For the AMR calls, this parameter, together with RXQUALn, is used in interference handover decision. An uplink interference handover is easily triggered if this parameter is set to a smaller value.

This parameter indicates the upper threshold of consecutive MRs containing no downlink measurement result for a call.Each call is configured with a global timer, which counts the number of consecutive MRs containing no downlink measurement.

You can set this parameter for the filter when the levels of a cell plunge.If you attempt to initiate the switchover upon quick level decrease, the decrease trend of cell levels must be increasingly remarkable as the filter parameter B becomes

Short message of cell broadcast DRX mode. Here, DRX means SMSBC DRX MODE (cell broadcast short message incontinuous receiving mode). BSC supporting SMSBC DRX must send scheduling message for MS to receive cell broadcast messages incontinuously. A scheduled message includes many broadcast messages to be sent in a cell. The duration occupied by the broadcast messages in scheduled message is called scheduled period. The scheduled message includes both the description of short

messages (arranged in the order of transmission sequence) to be broadcasted and their respective positions in the scheduled period. Therefore, MS can fetch the wanted broadcast message in the least time, and the power consumption is also decreased.

This parameter controls whether the BTS reports the voice quality index (VQI). Voice quality becomes better as the voice level decreases.

If this parameter is set to StartUp, the BSC sends the handoff command to the MS and adjusts the transmission power of the BTS to the maximum. During the handoff, the BSC does not change the BTS power to ensure the handoff success.

diversity port of another DRU through a tributary.Maximum value of N3105.

After the a downlink TBF is established, the network starts N3105.

After the network set the RRBP on the downlink RLC data block, it resets N3105 when receiving a valid packet acknowledgment message on the uplink RLC data block corresponding to the RRBP. Otherwise, N3105 is added on the network side and the network resends the downlink RLC data block where the RRBP is set.

When N3105 overflows, the network starts T3195. When T3195 expires, the current TBF is released abnormally

Maximum value of N3103.

If the network receives the last RLC data block when the uplink transmission is complete, it sends the MS a Packet Uplink Ack/Nack message with FAI=1 and starts N3103.

In uplink dynamic assignment mode, multiple MSs can share one uplink channel if the downlink data blocks carry the USF value.

After the network starts to assign a USF value to the uplink TBF (uplink TBF is established), N3101 is started. The network waits for the uplink data sent by the MS on the reserved uplink RLC block corresponding to the USF. If the MS sends a valid uplink RLC block, N3101 is reset. Otherwise, N3101 is added on the network side.

When this counter overflows, the current uplink TBF is released abnormally.

GPRS GSN provides subscribers with flexible QoS mechanism. The QoS level is determined in the subscription.

The QoS control parameters include the service priority class, reliability class, delay class, and throughput class.

During the negotiation of a QoS profile, an MS can apply a value for each QoS attribute. After receiving the request from the MS, the network negotiates a class for each attribute of each QoS profile based on the current effective GPRS resources. The network provides the negotiated QoS profile with corresponding resource.

Packet assignment refers to the assignment of a packet channel to the MS on the PACCH. Packet assignment involves only the move-down of the uplink packet assignment. To increase the access rate of MSs, after the packet assignment is moved down to the BTS, the BSC reserves uplink resources for the BTS. The BTS translates the downlink acknowledgment message sent

by the MS to obtain the channel request message, and assigns the reserved uplink resources to the MS. Then the MS can send data blocks.This parameter is based on the uplink immediate assignment.

To increase the access rate of MSs, the BSS pre-assigns uplink TBF resources to the BTS. When an MS sends a channel request, the BTS uses these pre-assigned resources to send the immediate assignment message to the MS. After receiving the immediate assignment message, the MS can send data blocks. The BTS also sends a secondary channel request message to

the BSC. After receiving this request message, the BSC sends a secondary immediate assignment message to the BTS to complete the TBF establishment.When both the MS and the network support PFC, the QoS parameters are obtained from the ABQP in the PFC.

When the MS or the network does not support PFC, the QoS parameters are obtained from the DL UNITDAT of the SGSN or from the uplink request of the MS.Default MCS type used on the downlink.

This parameter can be used to obtain the forgetting factor, which is used for the MS to calculate the measurement results.

During the data transmission process, the modulation scheme and coding scheme can be changed to dynamically adapt to the radio transmission environment, thus improving the quality of links.

- Setting and effect

Link Adaption (LA): The network dynamically adjusts the coding scheme of a channel based on the transmission quality of the channel link. The link quality is determined by 8PSK MEAN BEP and 8PSK CV BEP carried in the Packet EGPRS Downlink Ack/Nack message. The network selects a proper coding scheme for transmission based on the measurement reports from the

MS. For cells with good Um interface quality, the LA mode is usually used.

Incremental Redundancy (IR): The network should retransmit only different data blocks with the puncturing coding scheme. The MS buffers the history error information and the data blocks are retransmitted through combined error correction. In the cell with bad Um interface quality, the IR mode can achieve good transmission quality, but the MS must support this

mode. For cells with bad Um interface quality, the IR mode is usually used.

Hysteresis of cell reselection in the same routing area.

When an MS in the ready state performs cell reselection, if the originating cell and the target cell belong to the same routing area, the C2 value measured in the overlapped area of two adjacent cells fluctuates greatly because of the fading feature of radio channels. Therefore, the MS frequently performs cell reselection. The frequent cell reselection not only increases the

signaling flow on the network and affects the utilization of radio resources, but also greatly affects the data transmission rate of the MS and decreases the QoS as a consequence.

When this parameter is used, the MS starts cell reselection only when the signal level of the neighbor cells in the same routing area is higher than that of this cell, and when the signal level difference is greater than the value of this parameter.

Remarks None.

GPRS reselection offset is used to calculate C32. A higher value indicates a higher access priority.

The principles of cell reselection offset are as follows:

1 For the cell with low traffic and low equipment utilization, Huawei recommends that MSs work in the cell. The value range 0-20dB is recommended.

2 For the cell with medium traffic, value 0 is recommended.Timer used for the MS to calculate C32. The timer is sent through the system information broadcast in each cell.

When the BCCH frequency of a cell is listed in the neighbor cells for the MS, the negative offset of C2 is calculated before timer T expires.

This parameter is set to avoid the ping-pong cell reselection by the fast-moving MS. Therefore, the MS does not select this cell when the duration of signal strength on the BCCH is shorter than the penalty time.

nc0: Normal MS control. The MS performs automatic cell reselection.

nc1: MS control with measurement reports. The MS sends measurement reports to the network and performs automatic cell reselection.

nc2: Network control. The MS sends measurement reports to the network but does not perform automatic cell reselection.

Pan Max.is also the maximum value of N3102.

Value 4 indicates that Pan Max. is 4; value 32 indicates Pan Max. is 32; value nouse indicates that this parameter is not used.This parameter is used to set the value of N3102. When the MS receives a Packet Uplink Ack/Nack message that allows V(S) or V(A) increase, N3102 is increased by the value of this

parameter.

Value 0 indicates that Pan Increment is 0; value 7 indicates that Pan Increment is 7; value nouse indicates that this parameter is not used.This parameter is used to set the value of N3102. When T3182 expires, N3102 is decreased by the value of this parameter.

Value 0 indicates that Pan Decrement is 0; value 7 indicates that Pan Decrement is 7; value nouse indicates that this parameter is not used.

Maximum countdown value of the MS

This parameter is used for the MS to calculate CV. The parameter also determines the value of T3198.

Every time the MS sends an uplink RLC data block, it sets the receive state of the data block to Pending and starts T3198. If the MS receives a Packet Uplink Ack/Nack message before T3198 expires, it updates the receive state of each uplink RLC data block based on the acknowledgment bitmap contained in the message. If T3198 for the RLC data block in the Pending

state expires, the MS sets the receive state of this data block to Nack and resends it.

Control acknowledgment type. This parameter determines the acknowledgment message type used by the MS.

If four access pulses are used, the timing advance can be obtained without a polling message.

If the RLC/MAC control block is used, the timing advance can be obtained only by sending a polling message. Four access pulses are recommended.

Access burst type used by the MS in the PRACH, PTCCH/U, and packet control acknowledgment message.

8bit: access using the 8-bit burst.

11bit: access using the 11-bit burst.

Maximum duration of the non-DRX mode. DRX_Timer_Max (DRX: discontinuous reception) is a parameter carried by the cell broadcast message.

When the MS switches from the packet transfer mode to the packet idle mode, it stays in non-DRX mode for a period of time. After the TBF is released, the MS monitors all the CCCH blocks during the non-DRX mode period and the BSC6000 reserves the MS context. The reservation time depends on the smaller value among DRX_Timer_Max and NON_DRX_TIMER. NON_DRX_TIMER is negotiated with the SGSN during the GPRS attach of the MS and its value is usually high. Therefore, the reservation time actually depends on DRX_TIMER_MAX.

Value 0 indicates entering the DRX mode immediately.

Value 1 indicates entering the DRX mode one second later. Value n indicates entering the DRX mode n seconds later.

Timer set for the MS to wait for the TBF release after receiving the last data block.

When the MS receives the last RLC data block carrying the last block flag (FBI=1) and confirms that all the RLC data blocks on the TBF are received, the MS sends the Packet Downlink Ack/Nack message carrying the final acknowledgment flag (FAI=1) and starts T3192.

When T3192 expires, the MS releases the TBF resources and monitors paging channels. During the TBF release process, if the MS is in half-duplex mode and receives the Packet Uplink Assignment command, the MS responds to the command immediately.

If the MS does not receive the Packet Uplink Assignment command during the TBF release process, the MS enters the packet idle mode. If the MS is in dual transfer mode, it enters the dedicated mode.

Timer set for the MS to wait for the Packet Uplink Assignment message.

After the MS sends the Packet Resource Request or Packet Downlink Ack/Nack message carrying Channel Request Description, T3168 is started to wait for the Packet Uplink Assignment message from the network.

If the MS receives the Packet Uplink Assignment message before T3168 expires, T3168 is reset. Otherwise, the MS initiates the PS access procedure again for four times. If the Packet Uplink Assignment message is still not received, the MS regards this uplink TBF establishment as failure.

If the timer value is short, the time for the MS to decide that a TBF establishment fails is short. If a TBF establishment fails, the average delay of packet access is short, but the success rate of TBF establishment in bad radio environment decreases. In addition, the short timer value increases the probability of the retransmission of the packet access request, thus increasing

the probability of reassignment by the PCU. Therefore, many system resources are wasted. If the timer value is long, the time for the MS to decide that a TBF establishment fails is long. If a TBF establishment fails, the average delay of packet access is long, but the success rate of TBF establishment in bad radio environment increases.

Based on the paging channel used by the system, the network operation modes are classified into Network Operation Mode I, Network Operation Mode II, and Network Operation Mode III.

When the GS interface is configured, Network Operation Mode I is used.

When the Gs interface or the PCCCH is not configured, Network Operation Mode II is used.

When the Gs interface is not configured but the PCCCH is configured, Network Operation Mode III is used.

This parameter is used for the open loop power control.

ALPHA is used for the MS to calculate the output power on the uplink PDCH.

When the MS uses GPRS dynamic power control, this parameter determines the reduced level of the MS transmit power based on the path loss.

Initial power level.

This parameter determines the expected receive signal strength on the BTS side when the MS uses GPRS dynamic power control.

This parameter mainly affects the output power of the MS.

Signal strength filter length in packet idle mode.

This parameter is used when the MS measures the downlink signal strength in packet idle mode and calculates Cn of the MS output power. The parameter indicates the relation between Cn and Cn-1.

Signal strength filter length in packet transmission mode.

This parameter is used when the MS measures the downlink signal strength in packet transmission mode and calculates Cn of the MS output power. The parameter indicates the relation between Cn and Cn-1.This parameter determines the channel where the receive power level of the MS is measured for the uplink power control.Constant of the interference signal strength filtering by power control.

Remarks None.
