Description

Common control channel configuration is one of the system control parameters. In GSM system, CCCH includes Access Grant Channel (AGCH) and Paging Channel (PCH). It is used to send access granting (that is instant assignment) message and paging message.

In each cell, all service channels share CCCH. According to the configuration of the service channel in the cell and the traffic mode of the cell, CCCH could be one or more than one physical channel, and CCCH could share the same physical channel with SDCCH

The combination mode of the common control channel in cell depends on CCCH configuration parameter and it should be consistent with the actual configuration of cell CCH. It could be observed from this parameter: BS_CC_CHANS (Number of CCCH); BS_CCCH_SDCCH_COMB (If combined with SDCCH).

This parameter is broadcasted to all MSs in the cell by message RIL3_RR SYSTEM INFORMATION TYPE3.

Full name Periodical location updating timer

Abbreviation T3212

3GPP Name T3212

3GPP reference

3GPP TS 44.018 V5.13.0

Description

Location update results from two major causes in GSM system. One is when MS changes from old LAC to new LAC and the second is when the network notifies MS for periodic location update.

Network controls the location time interval and depends upon T3212 timer. Network broadcasts to all MSs in the cell by RIL3_RR SYSTEM INFORMATION TYPE3 message. T3212 timer is one of the system control parameters.

This parameter affects the overall service performance of the network and the utilization of the radio resource. For the area with higher traffic, the period could be bigger (for example 16 or 20 hours, even 25 hours); for the area with ordinary traffic, the value of T3212 could be smaller (for example 3 or 6 hours); for the area with extreme overload traffic, it is recommended to set T3212 as 0.

Description

BA indication of BCCH. Adjacent cell list can be broadcasted on BCCH and transferred on SACCH. The adjacent cell list transferred on BCCH can be different from that on SACCH. When MS reports the measurement data of adjacent cell, either BCCH adjacent cell list or SACCH adjacent cell list will be referred. Therefore, to know which adjacent cell list is referred by MS, a BA indication is added when transferring adjacent cell list on BCCH and SACCH. When reporting the measurement result, MS notifies the network side about the corresponding BA indication of the referred adjacent cell list. As a result, the network side recognizes which adjacent cell list this MS uses. This parameter describes the BS indication value when the adjacent cell list being transferred on BCCH. In the case of transferring adjacent cell list on SACCH, the BA indication value used is the reverse of the parameter.

Full name MIN received signal level to access

Abbreviation RxLevAccessMin

3GPP Name RXLEV_ACCESS_MIN

3GPP reference

3GPP TS45.008 V5.22.0

Description

MIN received signal level to access specifies the minimum received signal level for MS to access any cell. In general, GSM system specifies to keep the receiving level greater than a threshold in order to maintain communication speech quality.

In addition, the criterion assists MS to select and reselect the cell. System broadcasts parameter information to all MSs in a cell through RIL3_RR SYSTEM INFORMATION TYPE3 and TYPE4 messages. MIN received signal level to access is one of the cell selection parameters.

Recommended value is usually approximated according to MS receiving sensitivity. When network observes uneven traffic distribution in certain cells, MIN received signal level to access increases the resulting C1 and C2 to decrease the cell effective coverage range. However, the value of this parameter cannot be too large. Otherwise, large value change can bring ‘void area’ across cell boundaries to result in sudden call drop problem.

The value of this parameter must not exceed -90 dBm for cell traffic balancing conditions. At the preliminary running stage of the network, this parameter can be usually set as 10 (that is, -101 dBm ~ -100 dBm) or lower, which is higher than the MS receiving sensitivity –102 dBm. However, when the network capacity is expanded or the radio coverage in a cell is not a problem, this parameter of the cell can be increased by 2 (dB).

Description

MS sends the channel request message on RACH channel to the network to start immediate assignment process.

RACH is an ALOHA channel, the network enables MS to send multiple channel request messages before the MS receives the IMMEDIATE ASSIGNMENT message to increase the access success rate of MS. Maximum number of allowable resend time depends on MAX number of re-transmitting events times.

Network broadcasts this parameter information to MS in the cell through RIL3_RR SYSTEM INFORMATION TYPE1, 2, 2bis, 3 and 4’ messages. MAX number of re-transmitting events times is one of the control parameters of GSM system.

For the cell radius over 3km and the area with small traffic, it can be set as 3 (that is, the maximum number of resending times is 7) to improve the access success rate of MS.

For the cell radius less than 3km and the area with common traffic, it can be set as 2 (that is, the maximum number of resending times is 4);

Define value as 1 (maximum number of resending times is 2) for the micro cell.

Control channel MAX power level (MsTxPwrMaxCch)

T AB L E 49 - C O N T R O L C H AN N E L MAX P O W E R L E V E L

Full name Control channel MAX power level

Abbreviation MsTxPwrMaxCch

3GPP Name MS_TXPWR_MAX_CCH

3GPP reference

3GPP TS45.008 V5.22.0

Description

In the communication between MS and BTS, the transmission power is controlled by the network. The network sets the power of MS by power command, which is transmitted on SACCH (SACCH carries the power command with 2-header bytes information, one is power control byte and the other one is timing advance byte).

MS sets the specified output transmission power according to the power control header extracted from the SACCH. MS uses the nearest possible output power even if the power command sends maximum output power.

For SACCH is Channel Associated Signaling and it has to be used together with SCCCH and TCH, so the power control of MS starts after MS receives SACCH.

The power of MS before receiving SACCH (that is the power when sending channel request on RACH) is determined by Control channel MAX power level.

Control channel MAX power level is one of the cell selection and reselection parameters of MS, involving calculation of C1 and C2 values.

This parameter is broadcasted to all MS in the cell via RIL3_RR SYSTEM INFORMATION TYPE3 and TYPE4.

Refer to appendix C, for the maximum power before MS receives the power control information.

If this parameter is too large, the MS close to BTS will interfere with the adjacent channel; If it is too small, the MS access success rate at the edge of cell will be very low.

Setting principle: in the premise of certain MS access success rate at the cell edge, decrease the access level of MS as much as possible. Generally, it is recommended to set this parameter as 5 (for GSM900MS) and 0 (for GSM1800MS).

In practice, after setting this parameter, perform dialing test at the cell edge, increase or decrease the value of this parameter according to the MS access success rate and access time tested with different parameter setup.

Full name Number of multiframes of the PCH

Abbreviation BsPaMframs

3GPP Name BS-PA-MFRMS

3GPP reference

3GPP TS45.002 V5.13.0

Description

Number of multiframes of the PCH specifies the repeat cycle of PCH group subchannel using multiple 51-MultiFrame structures. It is one of the system control parameters.

According to GSM Specifications, a unique IMSI identifies MS and paging group. IMSI determines the PCH sub-channel for MS in a paging group.

In the actual network, MS tunes only to the paging sub-channel during IDLE mode in the serving cell and ignores other paging sub-channels. In other IDLE time, MS shuts off the hardware equipment power supply to save power. Number of multiframes of the PCH determines the number of paging sub-channels of the paging channel in a cell.

MS use this parameter to find out its home paging group, so as to monitor corresponding paging sub-channel. Network broadcasts the parameter information to all MSs in the cell through RIL3_RR SYSTEM INFORMATION TYPE3 message. Number of multiframes of the PCH is one of the system control parameters.

Description

This parameter is used at MS side. Number of slots to spread transmission belongs to PRACH control. Network broadcasts to MS through PSI1 message. Whenever establishing a new connection, MS sends a channel request message to the network through PRACH channel.

As PRACH is an ALOHA channel, to improve MS access success rate, the network allows MS to send multiple channel request messages before receiving packet assignment message. If MS does not receive any response for the previous channel request message, MS resends channel request message after waiting for a random period. Network uses S parameter to determine random waiting time.

3GPP Name EC



3GPP reference

3GPP TS 44.018 V5.22.0

Description

Generally, a valid SIM card is required for any MS in GSM Network to get various network services. But the operators could decide whether to allow MS emergency call service for the MS without SIM card or with SIM card whose access level is disabled by current cell, for example the police station. Select ‘Yes’ for Emergency call allowed to enable this function.

Network broadcasts the parameter information to MS in the cell through RIL3_RR SYSTEM INFORMATION TYPE1, 2, 2bis, 3 and 4, message. Call re-establishment allowed is one of the network function parameters.

Yes: Do not allow Emergency call for MSs whose access level is 0~9. For the MSs whose access level is 11~15, if its corresponding access control bit is T, the emergency call is also not allowed.

No: Allow Emergency call for all MSs

GSM specifications define emergency call phone number as 112, which is different from Chinese emergency call, but 112 is generally connected to the automatic voice service to inform the users about the number of various special services. Hence, EC should be set as ‘No’, that is to allow the emergency call.

3GPP Name AC CN, Access Control Class N

3GPP reference

3GPP TS 44.018 V5.22.0



Description

All MSs in GSM system have an access class (15 classes in total). The MSs that are in the class ranging between 0 and 9 are common ones. The MSs that are in the class ranging between 11 and 15 are special MSs (no access class 10). Therefore, the system can disable the MSs with certain access classes to access the cell (for example during the installation and commissioning or the congestion control). This information can reach MS inside the cell in RIL3_RR SYSTEM INFORMATION TYPE1, 2, 2bis, 3 and 4 messages through Access control. It is also one of the system control parameters.

The degree of congestion for any CCCH or processor overload during congestion control can be reduced by temporarily prohibiting one type or multiple types of subscribers from accessing the system (for subscribers of access levels 0 ~ 9). In general, the system shows the following overload conditions:

RACH overload, which should be found in the “CCCH LOAD INDICATION” message and processed by BSS according to the standard GSM08.58;

AGCH overload, which should be found in the “DELETE INDICATION” message first, and handled by BSS by not sending the “IMMEDIATE REJECT” message;

PCH overload, which should be found in the “CCCH LOAD INDICATION” message, and the BSS will not make any process but notify the MSC;

Other types of overload, which can be found in the “OVERLOAD” message, for example, MTP overload.

Description

The cell selection and reselection of MS depends on the C1 and C2 parameters, according to the definition in the GSM specification. Network carriers decide whether to use C2 as the cell reselection parameter. Additional reselection parameter indication is to notify MS whether C2 criterion is adoptable during the cell reselection.

Network broadcasts the parameter information to MS in the cell through RIL3_RR SYSTEM INFORMATION TYPE3 and TYPE4 messages. Additional reselection parameter indication is one of the cell selection parameters. Value Instruction:

Yes: MS takes off cell reselection parameter PI and the parameters related to computing C2 from the rest bytes ‘SI7/8 Rest Octets’ of SYSTEM INFORMATION TYPE 7 or 8.

No: MS should obtain the PI parameter related to the cell reselection and parameters related to the C2 calculation from the rest octets of the SYSTEM INFORMATION TYPE4 message (SI4 Rest Octets).

Generally, the system messages 7 and 8 are seldom used. Normally this parameter is ‘No’. It should be ‘Yes’ when the system adopts the system messages 7 and 8, and the cell reselection uses C2.

Reselection offset (ReselOffset)

Full name Reselection offset



Abbreviation ReselOffset

3GPP Name CELL_RESELECT_OFFSET

3GPP reference

3GPP TS 45.008 V5.22.0



Description

The cell reselection due to radio channel quality takes C2 as the standard. C2 is formed according to C1 parameter, and some special offset parameters, to add the special influence as to enable MS to enter some cells in priority. Usually, such measures allow balancing the traffic on the network.

Besides C1, there are three factors affecting C2: Cell reselection offset, Temporary offset, and Penalty time.

Cell reselection offset is a magnitude value, which indicates the human modified value of C2. Calculate a modified value of C2 to encourage or prevent MS accessing a certain cell, so as to implement balance network.

Network broadcasts the parameter information to all MSs in the cell through RIL3_RR SYSTEM INFORMATION TYPE3 and TYPE4 messages. It is one of the cell selection parameters. The validity of this parameter depends upon Cell reselection parameter indication.

The setting of Cell reselection offset, Temporary offset and the Penalty time are are classified into three cases:

In case of large traffic or poor communication quality inside a cell due to certain causes, normally MS is expected not to work in that cell (that is, certain repulsion to that cell).

Penalty time can be set as 31 in such cases. Temporary offset is invalid, and the numerical value of C2 equals C1 minus this parameter Cell reselection offset. Therefore, the C2 value corresponding to the cell is decreased, and reduces the possibility that MS reselecting the cell. Besides, the proper value of this parameter Cell reselection offset can be set according to the repulsive nature of cell. The more is the repulsive nature, the larger is the Cell reselection offset. Vice versa in case of a smaller Cell reselection offset.

For cells with small traffic and low equipment utilization, normally MS is encouraged to work in that cell (that is, certain propensity to that cell).

Cell reselection offset must be set between 0 ~ 10 (corresponding to 0 ~ 20 dB) in this case, according to tendency of the cell. The more is the tendency, the larger is the Cell reselection offset. Vice versa in case of a smaller Cell reselection offset. It is usually better to set the Temporary offset same as Cell reselection offset, or a little higher than Cell reselection offset. The main function of Penalty time is to avoid frequent cell reselection of MS. The common recommended setting is 1 (20 seconds) or 2 (40 seconds) (the 1800 cell of dual-frequency network is such a case).

For cells with ordinary traffic, usually “ReselOffset” should be set as 0 and “PenaltyTime” as 31. Thus, C2 is equal to C1, that is, without human factors on the cell.

Full name Cell reselecting hysteresis level

Abbreviation ReselHysteresis

3GPP Name CELL_RESELECT_HYSTERESIS

3GPP reference

3GPP TS 45.008 V5.22.0

Description

Whenever MS moves across the two cell boundary-regions with different location area codes, it initiates Location Update (LU) procedure in IDLE mode.

C2 values obtained at the boundary for two adjacent cells are different because of fading characteristic of radio channel. It causes MS to select cell frequently. In this case, LU interval is more than cell reselection interval. This affects call success rate, due to unreachable paging response to calling party.

This increases the signaling flow on the network and causes radio resources to be fully utilized. In addition, it decreases call completion rate of the system, as MS cannot respond to paging during location update.

In addition, value difference must be greater than the value specified in CRH.

Network broadcasts the parameter information to MS in the cell through RIL3_RR SYSTEM INFORMATION TYPE3 and TYPE4 messages. Cell reselecting hysteresis level is one of the cell selection parameters.

Define Cell reselecting hysteresis level to 4 or 5 and make certain adjustments in following cases:

Increase cell reselection parameters of adjacent cells with different LAC. Signaling traffic overload often occurs due to large demand of services.

When the adjacent cells in different location areas have large overlapped coverage, it is suggested to increase the CRH parameter.

If the adjacent cells with different LACs are poor in overlapped coverage, that is, there is coverage gap, or the adjacent place is an area with few slow moving objects such as the expressway, the CRH parameter should be set as 1 ~ 3 (that is, 2dB ~ 6dB for the CRH level).

There are three cases resulting in insufficient data for calculating the average value, that is, call establishment period, after handover and after power control. After performing power control once, former measured values are discarded in situations where they could result in an error control (measured values without the influence on handover control are still existing).

In addition, old measured values are discarded after the handover has occurred keeping it from causing error control (the forward and backward cells are in the same BSC).

3GPP reference

3GPP TS45.008 V5.22.0

Description

BTS needs to measure interference on the unallocated traffic channels. BTS calculates the average of recent interference values on periodic basis and converts it into corresponding interference band information. BTS then, transfers to BSC in the RF RESOURCE INDICATION message to consider it as a factor in channel allocation strategy.

The interface boundaries are used to help the conversion of the interference level (average) value into corresponding interference band information. Altogether six boundaries determine five interference bands. In fact, it is unnecessary to set interference boundary 0 and interference boundary 5. One represents infinity and the other represents negative infinity. This parameter, describing the remaining four boundaries, is one of the BTS configuration parameters.

Generally, -85 dBm ~ -115 dBm is used for interference boundaries 1 ~ 4.

Description

This parameter is the maximum value of radio link counter S at Ms side, transmitted on BCCH or SACCH by BSS. Radio link counter S is used to evaluate radio link failure. When MS can't decode SACCH message (BFI=1), S decrements; when MS successfully receives SACCH message (BFI=0), S increases by 2. If S is decreased to 0, it indicates radio link fault, call shall be reestablished or released.

Description

The network side (BTS) may judge whether the radio link fails according to two criteria: One is based on the uplink SACCH error rate and the other is based on measured value of RXLEV/RXQUAL. Radio link failure criterion determines the method that the BTS uses as the standard to judge connection failure.

If SACCH error rate is used as the standard to judge connection failure, BTS uses the same value of Radio link timeout and the same process as MS does. Thus, BTS avoids inconsistent judgment standards in the uplink and downlink directions. Meanwhile, the Receiving level threshold and Receiving quality threshold parameters are invalid.

If the measured value of RXLEV/RXQUAL is used as the standard to judge connection failure, BTS will use the two parameters Receiving level threshold and Receiving quality threshold.

The value range is as follows:

1: Uplink SACCH Error Rate Based (in order to ensure the same judgment standard in the uplink and downlink directions);

2: RXLEV/RXQUAL Measurement Based

The radio link is considered as failed if BTS detects one of the following conditions: The uplink receiving level is smaller than a certain threshold; The uplink receiving quality is greater than a certain threshold. This only applies, if the measured value of RXLEV/RXQUAL is used as the standard to judge a connection failure. Receiving level threshold specifies the threshold of receiving level.

This parameter is invalid if uplink SACCH error rate is used as the standard to judge connection failure (Radio link failure criterion is 1). Receiving level threshold is one of the configuration parameters of BTS.

Full name Multiband report indication

Abbreviation MulbandReport

3GPP Name MULTIBAND_REPORTING

3GPP reference

3GPP TS45.008 V5.22.0



Description

MS in single-frequency GSM system needs only to report contents of six adjacent cells with the strongest signals in a frequency band, when reporting the survey result of adjacent cells to the network.

In multi-band networking, MS can enter with priority into a specific frequency band during handover. The MS reports the survey result according to the signal intensity and the frequency band of the signals, according to the actual situation.

Multiband report indication is used to notify MS to report contents of adjacent cells in multiple frequency bands. It is one of the system control parameters.

The setting of this parameter is subject to traffic in each frequency band. General principles to set the parameters are as follows: 0: If the traffic of 　each frequency band is almost equivalent, and the operator has no choice over the frequency band.

3: If the traffic of each frequency band is quite 　different, and the operator hopes that MS enters a specific frequency band with priority.


0: MS reports the survey results of six known and allowed adjacent cells with the strongest NCC according to the signal intensity, regardless of which frequency band adjacent cells are in.

1: MS reports the measurement result of one adjacent cell with strongest signal in the frequency bands in adjacent cell list (excluding frequency band of serving cell). In the remaining space, MS reports adjacent cell in local cell frequency band. If still more space is available, MS reports the remaining adjacent cells, regardless of which frequency bands they are in.

2: MS reports the survey result of two adjacent cells with the strongest signals in the frequency bands (excluding that of local cell) in adjacent cell table. In the remaining space, MS reports adjacent cell in local cell frequency band. If still more space is available, MS reports the remaining adjacent cells, regardless of which frequency bands they are in.

3: MS reports the survey result of three adjacent cells with the strongest signals in the frequency bands (excluding that of local cell) in adjacent cell table. In the remaining space, MS reports adjacent cell in local cell frequency band. If still more space is available, MS reports the remaining adjacent cells, regardless of which frequency bands they are in.

That is, the frequency decreases from the original twice/s to once/2 s, so the message amount of Abis interface decreases. However, the decrease of message amount still depends on whether the message length before preprocess is same as that after preprocess. One disadvantage of preprocess is that the handover control and power control are not in time, which increases the possibility of disconnection rate. This parameter determines whether to use preprocess and its period or not.


0: Do not use preprocess

2: Use preprocess; the average reporting period is 2 SACCH multi-frames

Description

The cell selection and reselection of MS depends on the C1 and C2 parameters, according to the definition in the GSM specification. Network carriers decide whether to use C2 as the cell reselection parameter.

Additional reselection parameter indication is to notify MS whether C2 criterion is adoptable during the cell reselection.

System broadcasts through RIL3_RR SYSTEM INFORMATION TYPE3 and TYPE4 messages to MS in the cell. It is one of the cell selection parameters.


Yes: MS takes off cell reselection parameter PI and the parameters related to computing C2 from the rest bytes ‘SI7/8 Rest Octets’ of SYSTEM INFORMATION TYPE 7 or 8.

No: MS should obtain the PI parameter related to the cell reselection and parameters related to the C2 calculation from the rest octets of the SYSTEM INFORMATION TYPE4 message (SI4 Rest Octets).

Generally, system information TYPE 7 and TYPE 8 are rarely used, this parameter must be set as ‘No’, otherwise some MS (for example NEC) are not able to access the network.

3GPP TS 44.060 V5.19.0

Description

This parameter is used at MS side.

During the packet downlink transmission, if RLC data block is the final downlink data block to be transmitted, the network sends the RLC data block with the Final Block Identifier (FBI) domain as 1. It contains an effective RRBP field to initialize the release of the downlink TBF.

For each RLC data block that receives FBI with value 1 and contains effective RRBP domain:

In acknowledged mode, the MS sends PACKET DOWNLINK ACK/NACK message whose FBI domain is 1 on the uplink block specified by the RRBP domain.

In unacknowledged mode, MS sends the PACKET CONTROL ACKNOWLEDGE message in the uplink block specified as per RRBP field. Then MS starts the T3192 timer.

When T3192 stops, the system releases the resources, stops listening to the PDCCH channel, and turns to listen to the paging channel. Within the protection period of T3192, if the MS receives the “PACKET DOWNLINK ASSIGNMENT” or “PACKET TIMESLOT RECONFIGURE” message from the network, T3192 will stop and turn to the packet transmission status.

(2) When the MS detects the stall condition (V(S) = V(A) + W(S)), T3182 will start. When it receives the “PACKET UPLINK ACK/NACK” message that enables V(S) < V(A) + W(S), T3182 stops. If T3182 expires, the MS will subtract PanDec from N3102. When the condition satisfies N3102 < 0, the MS will take cell reselection as abnormal release. When one of PanDec, PanInc, and PanMax is zero, N3102 is invalid.

3GPP reference

3GPP TS 44.060 V5.19.0



Description

This parameter is used at MS side. It is broadcasted to MS via system message by BTS. MS needs to go through location updating process after cell reselection in the case of GPRS cell reselection, if the original cell and destination cell are in different locations. C32 values obtained at the boundary for two adjacent cells are different because of fading characteristic of radio channel. It causes MS to select cell frequently.

The interval between the two cell reselections of MS is not less than 15 s. However, 15 s is extremely short time in terms of location updating. This increases the signaling flow on the network and causes radio resources to be fully utilized. In addition, it decreases call completion rate of the system, as MS cannot respond to paging during location update.

GSM specification sets a specific parameter, Cell Reselecting Hysteresis (CRH), to solve this problem. MS will activate the cell reselection according to this parameter only when the signal level of adjacent cell (whose location zone is different from that of local cell) is greater than that of local cell, and meanwhile the value difference must be greater than that required by the parameter.




This parameter indicates the parameters used during reselection on idle status, which only functions while configuring PBCCH.

Description

This parameter is used at MS side. It is broadcasted to MS via system message by BTS. This parameter indicates the minimum receiving level while allowing MS access to this system (GPRS). To prevent the MS from accessing the system at a low receiving signal level (usually, the poor communication quality cannot guarantee normal communication process after access) and from unreasonably wasting radio resources of the network, it is stipulated in the GSM system that the receiving level be greater than a threshold level for MS to access the network, that is, “MS Minimal Level to Access”.

In addition, it is also one of the standards for MS to make the cell selection and the cell reselection (a parameter to calculate C31 and C32). This parameter indicates the parameters used during reselection on idle status, which only functions while configuring PBCCH.

This parameter is used at MS side. Number of slots to spread transmission belongs to PRACH control. Network broadcasts to MS through PSI1 message. Whenever establishing a new connection, MS sends a channel request message to the network through PRACH channel.

As PRACH is an ALOHA channel, to improve the success rate of MS access, the network allows MS to send multiple channel request messages before it receives the packet assignment message. If MS does not get any response for the previous channel request message, it can resend a channel request message after waiting for a random period. Interval range of packet access attempt is used to determine the time length of random waiting. It is the number of delay timeslot randomly connected.

Both interval range of packet access attempt (TxInt) and Interval period of packet access attempt (S) commonly determine random access time.

EGPRS phone quality measure mode (LinkQuameaMode)

T AB L E 252 - EGPRS P H O N E Q U AL I T Y M E A S U R E M O D E

Full name EGPRS phone quality measure mode

Abbreviation LinkQuameaMode

3GPP Name LINK_QUALITY_MEASUREMENT_MODE

3GPP reference

3GPP TS 44.060 V5.19.0

Description

This parameter is sent to MS in Downlink Assignment message. It indicates the measurement report mode of EGPRS MS in the cell. EGPRS measurement could be performed based on each impulse, which is to measure by the granularity of BURST. The feature of rapid EGPRS measurement makes the network side be able to respond the change of radio environment quickly, so as to choose the most proper coding mode and perform power control.
