Introduction to BSS RadioParameters900/1800 MHz TDMA digital celluar mobile communication system(GSM) is an integrated system covering fields of network tech-nology, digital stored program control technology, all transmissiontechnologies and radio technologies.
GSM consists of Network Sub System (NSS), Base Station Sub-system (BSS) and Mobile Station (MS).
GSM system signaling structure covers MAP interface, A-interface(between MSC and BSC), Abis interface (between BSC and BTS),Ater interface (between BSC and external TC) and Um interface(between BTS and MS, also called air interface).
All these objects and interfaces contain large quantity of configura-tion parameters and performance parameters, some of which aredetermined during the development and production of the equip-ment, and most of which depend on actual need and operation bynetwork providers. Settings and adjustment of latter parametershave a great impact on the operation of entire GSM network.
Radio parameters in GSM network refer to parameters related toradio devices and radio resources. These parameters have an im-portant impact on coverage of cells, distribution of signaling flowand service property of network, etc. Therefore, adjusting radioparameters reasonably plays a very important part in GSM net-work optimization.
GSM radio parameters are classified into project parameters andresource (cell) parameters.

1. Project parameters
Project parameters refer to parameters related to design,installation, and commissioning of the project, like antennaheight, antenna direction, antenna gain, antenna downloadobliquity and cable loss, etc. These parameters must bedetermined during network design and are seldom changedduring the operation of the network.
2. Resource (cell) parameters
Resource (cell) parameters refer to parameters related toconfiguration and utilization of radio resources, which usuallytransmit on radio interface (Um) to keep the base stationand mobile station consistent. Radio parameters covered inthis manual are mainly resource parameters. Radio resourceparameters in BSS contain:
� GERAN subnetwork parameters, BSC management NE pa-rameters, configuration set parameters;
� Global resource parameters for BSC, site parameters,GERAN external cell parameters, UTRAN external cellparameters;
� Cell Parameters;
� TRX parameters, power control parameters, handover con-trol parameters, UTRAN handover control parameters, ad-jacent interference cell parameters, adjacent handover cellparameters, adjacent reselection cell parameters, adjacenthandover and reselection cell parameters, UTRAN adjacentcell handover and reselection parameters, UTRAN adjacenthandover cell parameters, UTRAN adjacent reselection cellparameters, frequency hopping system parameters.

2. Some parameter values in the interface are not fully same asthose in database, with certain corresponding relationship be-tween them. For specific corresponding relationship see ap-pendix.
Precautions on ParameterAdjustmentRadio parameters adjustment, according to the type of the prob-lem to be solved, falls into two kinds.
� First is to solve static problem, that is, to correct traffic modelin system design by measuring actual average traffic and sig-

ZXG10 iBSC Radio Parameter Reference
naling flow in every district and to solve common problemsexisting for long.
� Second is to solve problems at a particular time like traffic over-load in some district, channel congestion due to sudden eventsor random events.
For the first type, service providers must perform measurementand summarization on actual operation regularly, and then per-form appropriate adjustment on global or partial parameters andconfigurations. For the second type, network operators adjustsome radio parameters at real time according to instant data frommeasurement results.
Most radio parameters in GSM system are based on one cell orone location area. It is necessary to consider whether parameteradjustment in this cell will influence other cells, especially the ad-jacent one, for parameters between cells are related to each othergreatly. Otherwise, it may cause negative influence. Determinewhether the problem results from equipment fault (including con-nections) first when it occurs in some part of the network. Adjustradio parameters only when determined that the problem does re-sult from service.

Description
This parameter defines that BSC automaticallyindicates to MSC about the ratio of presently availablechannels to the total channels. When available cellresource is lower than this parameter, resourceindication shall be sent to MSC about this cellcondition, which shall be configured by O&M.
The four modes of resource indication fromBSC are as follows:
� Automatic Mode: BSC instantly returns theBSSAP RESOURCE INDICATION message as anacknowledgment without any resource informationafter receiving the BSSAP RESOURCE REQUESTmessage. BSC automatically sends BSSAPRESOURCE INDICATION message to MSC. BSCuses the periodicity IE in BSSAP RESOURCEREQUEST to determine the indication messagesinterval (unless the ‘Periodicity IE’ is 0 andBSC ignores 0) once O&M of BSC satisfiesthe Auto condition (service threshold or theinterval between any two messages).
� One time mode: BSC instantly returns a BSSAPRESOURCE INDICATION message with resourceinformation after receiving BSSAP RESOURCEREQUEST message. BSC stops sending andwaits for next BSSAP RESOURCE REQUEST ifthe BSSAP RESOURCE REQUEST message doesnot contain Extended Resource Indication IE. Ifthere is Extended Resource Indication IE, BSCshall follow the regulations of Subsequent Modeelement in the message, same as mode 4. If theprevious one is mode 1 or 3, then you can usemode 1 or 3, otherwise you can use mode 4.
� Period mode: After BSC receives the “BSSAPRESOURCE REQUEST” message, it will immediatelyreturn a “BSSAP RESOURCE INDICATION”message that contains the resource information.After that, BSC periodically sends the “BSSAPRESOURCE INDICATION” message. If “PeriodicityIE” in the “BSSAP RESOURCE REQUEST” messageis not 0, then the period to send the message isthe value of “Periodicity IE” multiplied by 100 ms.If Periodicity IE is 0, then the message is wrongand the whole “BSSAP RESOURCE REQUEST”message is considered as incorrect.
� Stop mode: After the “BSSAP RESOURCEREQUEST” message is received, BSC immediatelyreturns a “BSSAP RESOURCE INDICATION”message without any resource information as anacknowledgement. And then, it will no longersend the cell resource information to MSC.

Overload contains overloads of CPU, MSC signalingpoint, MSC service, and CCCH.
In cell overload conditions, BSC adopts a timermT12 for traffic flow control. The mT12 timer incombination with mT11 timer modifies ACCESSCONTROL parameter in the cell. BSC notifies the MSto achieve flow control through system information.
The value of timer must be more than that of mT11timer. The two clocks control the cell flow as follows:When the network receives the overload message forthe first time, the system decreases the flow by onelevel, and starts mT11 and mT12. The OVERLOADmessage during mT11 period will be ignored. If theOVERLOAD message is received between mT11 andmT12, the flow will be decreased by another level andboth mT11 and mT12 will be restarted. If BSC doesnot receive OVERLOAD message after mT12 timerstops, the flow increases to one more level, and themT12 timer restarts. Lower grade and higher graderepresent different proportion to reject service.

Full name MAX times of BVC reset retry
Abbreviation BVCRestMax
3GPP Name BVC-RESET-RETRIES
3GPP refer-ence 3GPP TS48.018 V5.13.0
Description
To keep the initial status consistent between thetwo BVC sides, the “Reset BVC” process must beinitiated in the following cases: 1) system faultsthat affect the BVC function in BSS or SGSN (suchas restart upon power-on); 2) lower layer networkservice entity failure (such as frame relay fault); 3)lower layer network service entity capability update(for example, frame relay capability changed from0kbps to greater than 0kbps); 4) change of thecorresponding relationship between BVC and the cell.
For faults that affect NSE, BSC initiates SignalingBVC RESET procedure. For faults that affect asingle BVC, BSC initiates the PTP BVC RESETprocedure. BSC initiates all PTP BVC RESETprocedure for corresponding NSE after asignaling BVC reset procedure.
After the BVC RESET message is sent to SGSN,if the BVC RESET ACKNOWLEDGE message fromSGSN cannot be received within BSSGPT2, theBVC RESET process is repeated.
The BVC RESET process could be repeated for N timesat most. If there is no answer after the N times, BSCstops BVC RESET and notifies OMS. N depends onthe maximum number of retries of BVC RESET.

Description
This parameter is timer T3191. During the packetdownlink transmission, if the BSN of the RLC datablock to be transmitted is the maximum (that is,the final downlink data block), the network willsend a RLC data block whose Final Block Identifier(FBI) domain is 1 and which includes effectiveRRBP domain to initialize release of the downlinkTBF. Then the network starts T3191. For eachRLC data block that receives FBI with value 1and contains effective RRBP domain:
� In acknowledged mode, the MS sends PACKETDOWNLINK ACK/NACK message whose FBIdomain is 1 on the uplink block specified bythe RRBP domain. If the network receives the“PACKET DOWNLINK ACK/NACK” message beforeT3191 expires and has to re-transmit it, T3191is stopped and the required RLC data block isre-transmitted. If re-transmission is not required,T3191 is stopped and T3193 is started. WhenT3193 expires, the network releases TBF. Thenetwork also releases TBF when T3191 stops.
� In unacknowledged mode, MS sends the PACKETCONTROL ACKNOWLEDGE message in theuplink block specified as per RRBP field. T3191terminates to enable only when the networkreceives the PACKET CONTROL ACKNOWLEDGEmessage before T3191 stops. When T3193expires, the network releases TBF. The networkalso releases TBF when T3191 stops.

Description
This parameter is used to determine theincrease of coding mode level.
Unlike the unified coding mode of the circuitchannel, the GPRS data block may employ theCS-1 to CS-4 coding modes, with data rates9.05 kbps, 13.4 kbps, 15.6 kbps, and 21.4 kbps,respectively. The low level coding mode hashigher error correction capability and lower datathroughput. User can choose different codingmodes for each timeslot or even each TBF.
During data transmission of GRPR, to reach themaximum radio throughput, the network shallselect the coding mode dynamically according tothe data rate requirement and radio transmissionquality. Good radio transmission quality meansthat the probability of the retransmission of theerror radio blocks is small. In this time the codingmode that carries large data volume (that is,high level coding mode) can be used.
For TBF (uplink and downlink) in the channelcoding mode CSn (1≤n≤3), if the number of datablocks transmitted consecutively and correctlyexceeds the predefined parameter Cn[n-1], thecoding mode will be increased by one level.
Subscript 1, 2, and 3 in the interface arecoding conversion parameters among CS1~CS2,CS2~CS3, and CS3~CS4.

� x02: Indicates the enhanced Radio Status processis used when the cell reselection occurs. Usually,it helps satisfy the service requirement to themaximum extent.
� x03: Indicates the enhanced Radio Status processis used when the MS is required to perform cellreselection and LLC frame transferring is notsupported.
� x04: Indicates that SGSN is notified when BSCdetects cell reselection failure.
SGSN has the following responses:
� When Radio Status with the cause value x02is received, the downlink LLC frame sending isresumed after cell reselection is completed.
� When Radio Status with the cause value x03is received, either the downlink data sending isresumed after cell reselection is completed, orRadio Status with other cause values are received.
� When Radio Status with the cause value x04 isreceived, if there are data to be sent to MS, thenthe downlink LLC frame sending is resumed.
With Radio Status that supports multiple cause values,SGSN can better understand the status of MS, whichavoids sending data to the old cell blindly.

Description
NCC is one of the composition parts of Base StationID Code (BSIC) (BSIC = NCC + BCC). which is usedto enable the MS to distinguish adjacent and differ-ent GSM PLMN cells. Normally, adjacent operatorsshall have different NCCs. The parameter related toNCC is “NccPermitted” of the cell. By prohibiting MSto report related NCC in the cell, MS is prohibited tomeasure the cell information of the related opera-tors. Actually, NCC occupies three bits. NCC is oneof the network identification parameters.

Description
This parameter is used at MS side. It is broadcastedto MS via system message by BTS. Network controlsthe MS transmit power during communicationwith BTS. The network controls MS power usingpower command. MS outputs transmit powerclosest to the specified power value if unavailable.The power before MS receives the networkpower control information (the power used inrandom access), depends on this parameterwhen MS is receiving PBCCH.
This parameter is also a parameter for cellselection and reselection by MS, involved incalculation of C1 and C2 values.
Refer to Appendix C, for the maximum power beforeMS receives the power control information.
The principle of setting this parameter is asfollows: Under the precondition that the MS atthe cell boundary is guaranteed with a certainaccess success rate, the MS access level shouldbe reduced as much as possible. Generally, itis recommended to set this parameter as 5 (forGSM900MS) and 2 (for GSM1800MS).
In actual application, after the parameter is set,make a dial test at the cell boundary, and test MSaccess success rate and access time with differentparameter settings to determine whether to increaseor decrease the value of the parameter.

GPRS system divides thelocation area (LAs) to several routing areas (RAs)using RAI (MCC+MNC+LAC+RAC). Routing Area(RA) distribution, similar to GSM system, usesthe location area to manage a group of cells.MS initiates ‘Routing area update’ procedure incell reselection mode if new RAI differs fromold RAI during cell reselection.
SGSN knows the routing area information ofthe MS in the standby status. Then, when thenetwork has packet data or circuit data to transmit,it will page the MS in that routing area. RAIcannot span more than one SGSN.

Location update results from two major causes inGSM system. One is when MS changes from old LACto new LAC and the second is when the networknotifies MS for periodic location update.
Network controls the location time interval anddepends upon T3212 timer. Network broadcaststo all MSs in the cell by RIL3_RR SYSTEMINFORMATION TYPE3 message. T3212 timer isone of the system control parameters.
The setting of this parameter will affect theoverall service performance and utilization rateof radio resources of the network. For the areawith higher traffic, the period could be bigger(for example 16 or 20 hours, even 25 hours); forthe area with ordinary traffic, the value of T3212

Description
MS in single-frequency GSM system needsonly to report contents of six adjacent cellswith the strongest signals in a frequencyband, when reporting the survey result ofadjacent cells to the network.
In multi-band networking, MS can enter with priorityinto a specific frequency band during handover.The MS reports the survey result according to thesignal intensity and the frequency band of thesignals, according to the actual situation.
Multiband report indication is used to notifyMS to report contents of adjacent cells inmultiple frequency bands. It is one of thesystem control parameters.
The setting of this parameter is subject to trafficin each frequency band. General principles to setthe parameters are as follows: 0: If the traffic ofeach frequency band is almost equivalent, and theoperator has no choice over the frequency band.3: If the traffic of each frequency band is quitedifferent, and the operator hopes that MS entersa specific frequency band with priority.
The values are as follows:
� 0: According to adjacent cell's signal strength,MS reports the measurement result of sixadjacent cells with the strongest known andpermitted NCC. This report is applicable foradjacent cells of all frequency bands.
� 1: MS reports the measurement result ofan adjacent cell with the strongest signalat frequency bands in the adjacent cell list(excluding frequency band of the local cell).In the remaining space, MS reports adjacentcells which are at the local cell's frequencyband. If there is still remaining space, MSreports the remaining adjacent cells, no matterwhat frequency bands they are at.
� 2: MS reports the measurement result oftwo adjacent cells with the strongest signalat frequency bands in the adjacent cell list(excluding frequency band of the local cell).In the remaining space, MS reports adjacentcells which are at the local cell's frequencyband. If there is still remaining space, MSreports the remaining adjacent cells, no matterwhat frequency bands they are at.
� 3: MS reports the measurement result ofthree adjacent cells with the strongest signalat frequency bands in the adjacent celllist (excluding frequency band of the localcell). In the remaining space, MS reportsadjacent cell in local cell frequency band. Ifstill more space is available, MS reports theremaining adjacent cells, no matter whatfrequency bands they are at.

When MS reportsthe measurement data of adjacent cell, eitherBCCH adjacent cell list or SACCH adjacent celllist will be referred. Therefore, to know whichadjacent cell list is referred by MS, a BA indication isadded when transferring adjacent cell list on BCCHand SACCH. When reporting the measurementresult, MS notifies the network side about thecorresponding BA indication of the referred adjacentcell list. As a result, the network side recognizeswhich adjacent cell list this MS uses.
This parameter describes the BS indication valuewhen the adjacent cell list being transferredon BCCH. In the case of transferring adjacentcell list on SACCH, the BA indication value usedis the reverse of the parameter.

Full name MIN received signal level to access
Abbreviation RxLevAccessMin

3GPP reference 3GPP TS45.008 V5.22.0
Description
To prevent the MS from accessing the systemat a low receiving signal level (usually, thepoor communication quality cannot guaranteenormal communications after access), andfrom unreasonably wasting the radio sources ofnetwork, it is prescribed in the GSM system thatthe receiving level be greater than a thresholdfor MS to access the network, that is, MS MinRxLev to Access (the minimum receiving levelfor the MS to access the network).
In addition, the criterion assists MS to selectand reselect the cell. The parameter will bebroadcast to all MSs in a cell through the “RIL3_RRSYSTEM INFORMATION TYPE3” and “TYPE4”messages. MIN received signal level to access isone of the cell selection parameters.
Recommended value is usually approximatedaccording to MS receiving sensitivity. Whennetwork observes uneven traffic distribution incertain cells, MIN received signal level to accessincreases the resulting C1 and C2 to decrease thecell effective coverage range. However, the valueof this parameter cannot be too large. Otherwise,large value change can bring ‘void area’ across cellboundaries to result in sudden call drop problem.
With this measure for traffic balance, it is suggestedthat the level value should not exceed -90dBm. Atthe preliminary running stage of the network, thisparameter can be usually set as 10 (that is, -101dBm ~ -100 dBm) or lower, which is higher thanthe MS receiving sensitivity –102 dBm. However,when the network capacity is expanded or the radiocoverage in a cell is not a problem, this parameterof the cell can be increased by 2 (dB).

Chapter 4 Cell Parameters
Description
This parameter is used at MS side. It belongs tothe PRACH control and RACH control parameters,and it is broadcast to the MS in the PSI1 message.Whenever establishing a new connection, MSsends a channel request message to the networkthrough PRACH/RACH channel.
As PRACH/RACH is an ALOHA channel, to improveMS access success rate, the network allowsMS to send multiple channel request messagesbefore receiving packet assignment message.If MS does not receive any response for theprevious channel request message, MS resendsthe channel request message after waiting for arandom period. Network uses this parameter todetermine the random waiting time.
The timeslot interval between two channel requestmessages should be a value randomly selectedfrom the set {S, S+1..., S+T-1}.
The relationship between S and T is as follows.
� When T is 3, 8, 14, or 50, S: 55 (CCCH);41 (CCH/SDCCH)
� When T is 4, 9, or 16, S: 76 (CCCH);52 (CCH/SDCCH)

Control channel MAX power level(MsTxPwrMaxCch)
Full name Control channel MAX power level
Abbreviation MsTxPwrMaxCch
3GPP Name MS_TXPWR_MAX_CCH
3GPP reference 3GPP TS45.008 V5.22.0
Description
During the communication between MS andBTS, the transmission power is controlled by thenetwork. The network sets the power for MSthrough the power command and the commandis transmitted on SACCH (SACCH has 2 headerbytes, one is the power control byte and theother is the timing advance byte).
MS must extract the power control headerfrom downward SACCH and takes the specifiedtransmission power as output power. If thepower level of MS cannot output the powervalue, it will output the closest transmissionpower that can be output.
For SACCH is Channel Associated Signaling and ithas to be used together with SCCCH and TCH, so thepower control of MS starts after MS receives SACCH.
The power of MS before receiving SACCH (that isthe power when sending channel request on RACH)is determined by Control channel MAX power level.
Control channel MAX power level is one of thecell selection and reselection parameters of MS,involving calculation of C1 and C2 values.
This parameter is broadcasted to all MS in the cell viaRIL3_RR SYSTEM INFORMATION TYPE3 and TYPE4.
Refer to appendix C, for the maximum power beforeMS receives the power control information.
If this parameter is set too large, the MS nearBTS will interfere the adjacent channels. If itis too small, the MS at the cell boundaries willhave low access success rate.
Setting principle: in the premise of certain MSaccess success rate at the cell edge, decrease theaccess level of MS as much as possible. Generally,it is recommended to set this parameter as 5 (forGSM900MS) and 0 (for GSM1800MS).
In practice, after setting this parameter, performdialing test at the cell edge, increase or decrease

Description
All MSs in GSM system have an access class (15classes in total). The MSs that are in the classranging between 0 and 9 are common ones. TheMSs that are in the class ranging between 11 and15 are special MSs (no access class 10). Therefore,the system can disable the MSs with certain accessclasses to access the cell (for example during theinstallation and commissioning or the congestioncontrol). This information can reach MS inside thecell in RIL3_RR SYSTEM INFORMATION TYPE1, 2,2bis, 3 and 4 messages through Access control. Itis also one of the system control parameters.
The degree of congestion for any CCCH or processoroverload during congestion control can be reducedby temporarily prohibiting one type or multipletypes of subscribers from accessing the system (forsubscribers of access levels 0 ~ 9). In general, thesystem shows the following overload conditions:
� RACH overload should be detected in the CCCHLOAD INDICATION message and processedby BSS according to the GSM08.58.
� AGCH overload should be detected in theDELETE INDICATION message. At that moment,the number of IMMEDIATE REJECT messages orIMMEDIATE ASSIGNMENT messages that BSSfails to send reaches a certain number.
� PCH overload should be detected in the CCCHLOAD INDICATION message, and BSS onlynotifies MSC and does not do any handling.

Chapter 4 Cell Parameters
Description
The cell reselection due to radio channel qualitytakes C2 as the standard. C2 is formed according toC1 parameter, and some special offset parameters,to add the special influence as to enable MS toenter some cells in priority. Usually, such measuresallow balancing the traffic on the network.
Besides C1, there are three factors affectingC2: Cell reselection offset, Temporaryoffset, 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 encourageor prevent MS accessing a certain cell, so asto implement balance network.
Network broadcasts the parameter informationto all MSs in the cell through RIL3_RR SYSTEMINFORMATION TYPE3 and TYPE4 messages. It isone of the cell selection parameters. Whether thisparameter is valid depends on CellReselPI.
The setting of ReselOffset, TemporaryOffset, andPenaltyTime has the following three cases:
� In case of large traffic or poor communicationquality inside a cell due to certain causes, MSis expected not to work in that cell (that is,MS has certain repulsion to that cell).
Penalty time can be set as 31 in such cases.Temporary offset is invalid, and the numericalvalue of C2 equals C1 minus this parameterCell reselection offset. Therefore, the C2 valuecorresponding to the cell is decreased, andreduces the possibility that MS reselectingthe cell. Besides, the proper value of thisparameter Cell reselection offset can be setaccording to the repulsive nature of cell. Themore is the repulsive nature, the larger isthe Cell reselection offset. Vice versa in caseof a smaller Cell reselection offset.
� For cells with small traffic and low equipmentutilization, normally MS is encouraged to work inthat cell (that is, certain propensity to that cell).
Cell reselection offset must be set between0 ~ 10 (corresponding to 0 ~ 20 dB) in thiscase, according to tendency of the cell. Themore is the tendency, the larger is the Cellreselection offset. Vice versa in case of asmaller Cell reselection offset. It is usuallybetter to set the Temporary offset same as Cellreselection offset, or a little higher than Cellreselection offset. The main function of Penaltytime is to avoid frequent cell reselection of MS.The common recommended setting is 1 (20seconds) or 2 (40 seconds) (the 1800 cell ofdual-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 cellboundary-regions with different locationarea codes, it initiates Location Update (LU)procedure in IDLE mode.
C2 values obtained at the boundary for two adjacentcells are different because of fading characteristic ofradio channel. It causes MS to select cell frequently.In this case, LU interval is more than cell reselectioninterval. This affects call success rate, due tounreachable paging response to calling party.
This increases the signaling flow on the networkand causes radio resources to be fully utilized.In addition, it decreases call completion rateof the system, as MS cannot respond topaging during location update.
GSM specification sets a specific parameter, CellReselecting Hysteresis (CRH), to solve this problem.MS will activate the cell reselection according to thisparameter only when the signal level of adjacentcell (whose location zone is different from that oflocal cell) is greater than that of local cell, andmeanwhile the value difference must be greaterthan that required by the parameter.
Network broadcasts the parameter informationto MS in the cell through RIL3_RR SYSTEMINFORMATION TYPE3 and TYPE4 messages.Cell reselecting hysteresis level is one of thecell selection parameters.
Define Cell reselecting hysteresis level to 4 or 5 andmake certain adjustments in following cases:

� Increase cell reselection parameters of adjacentcells with different LAC. Signaling traffic overloadoften occurs due to large demand of services.
� When the adjacent cells in different locationareas have large overlapped coverage, it issuggested to increase the CRH parameter.
� If the adjacent cells with different LACs arepoor in overlapped coverage, that is, thereis coverage gap, or the adjacent place is anarea with few slow moving objects such as theexpressway, the CRH parameter shall be set as1 ~ 3 (that is, 2dB ~ 6dB for the CRH level).

Description
The network side (BTS) may judge whether the radiolink fails according to two criteria: One is based onthe uplink SACCH error rate and the other is basedon measured value of RXLEV/RXQUAL. Radio linkfailure criterion determines the method that the BTSuses as the standard to judge connection failure.
If SACCH error rate is used as the standard tojudge connection failure, BTS uses the same valueof Radio link timeout and the same process as MSdoes. Thus, BTS avoids inconsistent judgmentstandards in the uplink and downlink directions.Meanwhile, the Receiving level threshold andReceiving quality threshold parameters are invalid.
If the measured value of RXLEV/RXQUAL is usedas the standard to judge connection failure,BTS will use the two parameters: Receivinglevel threshold (RxLevThs) and Receivingquality threshold (RxQualThs).
The value range is as follows:
� 1: Uplink SACCH Error Rate Based (in orderto ensure the same judgment standard inthe uplink and downlink directions)

This only applies, if the measured valueof RXLEV/RXQUAL is used as a standard to judgea connection failure. Receiving quality thresholdspecifies the receiving threshold quality.
If the uplink SACCH error rate is used as thestandard to judge a connection failure, thisparameter is invalid. This parameter is one ofthe configuration parameters of BTS.

Description
The survey report contains the large amount(message amount) of Abis interface information.Preprocess of the survey report can be transferred toBTS to reduce the burden of Abis interface link. Afterpreprocess, BTS averages the survey data of MS byits own, and reports to BSC in a lower frequency.
Average reporting period can be two, three orfour SACCH multi-frames (480 ms). That is,the frequency decreases from the original twiceper second to once per two seconds, so themessage amount of Abis interface decreases.However, the decrease of message amountstill depends on if the message length beforepreprocess is same as that after preprocess. Onedisadvantage of preprocess is that the handovercontrol and power control are not in time, whichincreases the possibility of disconnection rate. Thisparameter determines whether to use preprocessingand the preprocessing period.
The values are as follows:
� 0: Do not use preprocessing� 2: Use preprocessing, the average reporting

This parameter is used at MS side. SI13sending position indicates the schedulingposition of SI13 on BCCH.
SI13 is related to the GPRS services. SI13 canbe sent on either of the following two positions:BCCH Norm position (in this case, it occupiesthe BCCH block with TC = 4; TC = ((FN DIV 51)mod (8))), BCCH Ext position (in this case, itoccupies the AGCH block with TC = 0).
When SI13 is transmitted on BCCH Ext position, itoccupies one fixed AGCH block with TC = 0. SI13 issent with low success rate on the BCCH Ext position,because SI13 has to compete with other messages,such as IMMEDIATE ASSIGNMENT message, fordelivery opportunity. For this case, the parametervalue of Access Allowed Reserved Blocks must beset greater than 0. Otherwise, SI13 will not be sent.

Chapter 4 Cell Parameters
Description
Parameter used at the MS side.
During the packet downlink transmission, if RLCdata block is the final downlink data block to betransmitted, the network sends the RLC data blockwith the Final Block Identifier (FBI) domain as1. It contains an effective RRBP field to initializethe release of the downlink TBF.
For each RLC data block that receives FBI withvalue 1 and contains effective RRBP domain:
� In acknowledged mode, the MS sendsPACKET DOWNLINK ACK/NACK messagewhose FAI domain is 1 on the uplink blockspecified by the RRBP domain.
� In unacknowledged mode, MS sends thePACKET CONTROL ACKNOWLEDGE message inthe uplink block specified as per RRBP field.Then MS starts the T3192 timer.
T3192 releases the resources, stop discreetlistening to the PDCCH channel when it expires, andturns to the paging channel for discreet listening.Within the protection period of T3192, if the MSreceives the “PACKET DOWNLINK ASSIGNMENT”or “PACKET TIMESLOT RECONFIGURE” messagefrom the network, T3192 will stop and turn tothe packet transmission status.

ZXG10 iBSC Radio Parameter Reference
Description
This parameter is used at MS side. It is broadcastedto MS via system message by BTS.
MS needs to go through location updating processafter cell reselection in the case of GPRS cellreselection, if the original cell and destination cellare in different locations. C32 values obtained atthe boundary for two adjacent cells are differentbecause of fading characteristic of radio channel.It causes MS to select cell frequently.
The interval between the two cell reselectionsof MS is not less than 15 s. However, 15 sis extremely short time in terms of locationupdating. This increases the signaling flow on thenetwork and causes radio resources to be fullyutilized. In addition, it decreases call completionrate of the system, as MS cannot respond topaging during location update.
GSM specification sets a specific parameter, CellReselecting Hysteresis (CRH), to solve this problem.MS will activate the cell reselection according to thisparameter only when the signal level of adjacentcell (whose location zone is different from that oflocal cell) is greater than that of local cell, andmeanwhile the value difference must be greaterthan that required by the parameter.
� Increase cell reselection parameters of adjacentcells with different LAC. Signaling traffic overloadoften occurs due to large demand of services.
� When the adjacent cells in different locationareas have large overlapped coverage, it issuggested to increase the CRH parameter.
� If the adjacent cells with different LACs arepoor in overlapped coverage, that is, thereis coverage gap, or the adjacent place is anarea with few slow moving objects such as theexpressway, the CRH parameter should be setas 1 ~ 3 (that is, 2dB ~ 6dB for the CRH level).

Abbreviation MsTxMaxCch_0
3GPP Name GPRS_MS_TXPWR_MAX_CCH
3GPP reference 3GPP TS 45.008 V5.22.0
Description
This parameter is used at MS side. It is broadcastedto MS via system message by BTS.
Network controls the MS transmit power duringcommunication with BTS. The network controlsMS power using power command. MS outputstransmit power closest to the specified powervalue if unavailable. The power before MS receivesthe network power control information (thepower used in random access), depends on thisparameter when MS is receiving PBCCH.
This parameter is also a parameter for cell selectionand reselection by MS, involved in calculation ofC1 and C2 values. If this parameter is too large,the MS close to BTS will interfere with the adjacentchannel; If it is too small, the MS access successrate at the edge of cell will be very low.
To set it, observe the following principle: Under theprecondition that the MS at the cell boundary isguaranteed with certain access success rate, the MSaccess level should be reduced as much as possible.Generally, it is recommended to set this parameteras 5 (for GSM900MS) and 2 (for GSM1800MS).
In actual application, after the parameter is set,make a dial test at the cell boundary, and test MSaccess success rate and access time with differentparameter settings to determine whether to increaseor decrease the value of the parameter.
The value is same as that in the appendix.
This parameter indicates the parameters usedduring reselection on idle status, which onlyfunctions while configuring PBCCH.

Description
This parameter is used at MS side. It belongs to thePRACH control parameters, and it is broadcast tothe MS in the PSI1 message. Whenever establishinga new connection, MS sends a channel requestmessage to the network through PRACH channel.
As PRACH is an ALOHA channel, to improve thesuccess rate of MS access, the network allows MSto send multiple channel request messages beforeit receives the packet assignment message. If MSdoes not get any response for the previous channelrequest message, it can resend a channel requestmessage after waiting for a random period. Intervalrange of packet access attempt is used to determinethe time length of random waiting. It is the numberof delay timeslot randomly connected.
The random access time is determined by Intervalrange of packet access attempt (TxInt) and Intervalperiod of packet access attempt (S).

Description
During communication, the carrier number adoptedon air interface is an element of the MA set. MobileAllocation Index (MAI) (0 ≤ MAI ≤ n-1) is a variablefor determining a definite element in the MA set.
According to the FH algorithm in GSM 05.02specification, MAI is function of the followingaspects: TDMA Frame Number (FN) or ReducedTDMA Frame Number (RFN), frequency HoppingSerial Number (HSN), and Mobile Allocation IndexOffset (MAIO). MAIO is an initial offset of MAI andis used for preventing several channels to contendfor the same carrier at the same moment.
Generally, several basic FH units (timeslot orTDMA frame) constitute an FH group. They havethe same MA and HSN and the only differenceamong them is MAIO. Thus the same MA and HSNare put in FHS/MA table. When the FH groupcorresponding to the timeslot has no frequencyhopping, MAIO of the timeslot is invalid.

Description
Speech data is unavailable for silent period duringconversation. GSM specifications recommendDiscontinuous Transmission Mode (DTX) tocontrol optimal usage of network resourcesduring such silent periods.
In the DTX mode, the measurement data reportedto BSC fall into two types. One is the averageof the measurement results of all timeslots in ameasurement period in the non-DTX mode, andthe other is the average of the measurementresults of some special timeslots in a measurementperiod in the DTX mode. BSC needs to optionallyselect one type of measurement data and usethe data to calculate the average value.
The first type of measurement data is more accuratesince it is the average value of measurement resultsof all timeslots. The second type of measurementdata is less accurate since it is the average value ofmeasurement results of some timeslots. Thus BSCshould use different weights for the two types ofdata when averaging the measurement results.
This parameter determines the weight for thefirst type of measurement data when averaginguplink signal strength for power control.Weight for the second type of measurementdata is set to 1 by default.

Abbreviation MsTxPwrMin_0 ~ MsTxPwrMin_3
3GPP Name None
3GPP reference 3GPP TS 45.008 V5.22.0
Description
During the communication between MS andBTS, the transmission power is controlled by thenetwork. The network sets the power for MSthrough the power command and the commandis transmitted on SACCH (SACCH has 2 headerbytes, one is the power control byte and theother is the timing advance byte).
MS sets the specified output transmission poweraccording to the power control header extractedfrom the SACCH. MS uses the nearest possibleoutput power even if the power command sendsmaximum output power. During BSC powercontrol, this parameter determines the minimumtransmission power (that is, lower limit of powercontrol) available for MS in the cell.
The value is same as that in the appendix.

Description: According to GSM Specifications,discontinuous transmission (DTX) refers to theprocess in which the system does not transmitsignals in the voice intermittent period duringthe subscriber communication process.
In the DTX mode, the measurement data reportedto BSC fall into two types. One is the averageof the measurement results of all timeslots in ameasurement period in the non-DTX mode, andthe other is the average of the measurementresults of some special timeslots in a measurementperiod in the DTX mode. BSC needs to optionallyselect one type of measurement data and usethe data to calculate the average value.
The first type of measurement data is more accuratesince it is the average value of measurement resultsof all timeslots. The second type of measurementdata is less accurate since it is the average value ofmeasurement results of some timeslots. Thus BSCshould use different weights for the two types ofdata when averaging the measurement results.
This parameter determines the weight for the firsttype of measurement data when averaging uplinksignal strength for handover. Weight for the secondtype of measurement data is set to 1 by default.

Downlink receive level of intra-ho Value N(IntraHoDlLevN) / Value P (IntraHoDlLevP)
Full name Downlink receive level of intra-ho Value N / Value P
Abbreviation IntraHoDlLevN / IntraHoDlLevP
3GPP Name None
3GPP reference 3GPP TS 45.008 V5.22.0
Description
According to GSM specifications, handover decisionsdepend upon received average value of uplinkand downlink signal strength.
The decision process is as follows: For the latest Naverage values of downlink signal strength, if P ofthe N values rise above relevant threshold value,then perform handover. The handover is due tostrong downlink co-frequency interference.
Parameter "IntraHoDlLevThs" defines the relatedthreshold, parameter "IntraHoDlLevN" defines therelated N value, and parameter "IntraHoDlLevP"defines the related P value. If this handovercondition is met, an internal handover isusually performed in the cell.
Usually the value of "IntraHoDlLevThs" shallbe less than (or equal to) the threshold fordownlink power control (decrease).

Description
During fast fading handover, some parametersshall be used. If the measured signal intensityof a call is less than rapid handover threshold,then it triggers handover of existing cell tomost probable candidate cell.
RapidHoN counter defines the minimum timesfor which the measured signal intensity of acall is less than the threshold.
"RapidHoThs" may be set as 15 (that is, -96dBm ~-95dBm) by default, the same as the level thresholdof ordinary handover. Parameter "RapidHoN" shouldbe set to ensure that rapid handover is fasterthan the ordinary signal level handover.

Description
This parameter specifies the interval value for whichMS waits before the actual inter-cell handoveroccurs. Such a timer is more predominant forMS at the boundary regions between two cells,where inter-cell handovers occur frequently.This parameter helps restrict frequent inter-cellhandover and guarantees call quality.
Inter-cell handover takes place when the timerexceeds the defined interval value from thelast inter-cell handover of MS. This parameteraffects only the inter-cell handover, but notcommon intra-cell or inter-cell concentric handover.In addition, micro-cell has its own handoverpolicy, so this parameter is only effective formacro-cell layer and its above layer.
For macro-cell, the default value can be 5; formicro-cell, the default value can only be 0.

Description
Directed handover is performed only for onedesignated cell and it is restricted by a tolerablelevel difference MaxLevDiff. This level differenceis lower than PBGT handover threshold in reversedirection, thus to avoid oscillating handover.
Directed handover should not cause congestionin the destination cell. Therefore, HoForceResThsis set. Perform forced handover only when thedestination cell's resource is less than the threshold.
Select users with small path loss and small TA forforced handover. Users perform handover whentheir path loss are less than MaxLossThs and TA isless than MaxTAThs. This algorithm applies to casessuch as dual-frequency networking, 900M cell and1800M cell share the same site address.
When MAX time advance threshold on forcehandover (MaxTAThs) is 63, the forced handoverdecision is made only according to the pathloss. When MAX path loss threshold on forcehandover (MaxLossThs) is 150, the forced handoverdecision is made only according to TA.
The N value of force handover parameter andP value of force handover parameter are usedfor decision in actual situations. In other words,handover conditions are met if HoForceP of HoForceNmeasurement reports satisfy requirement.
The path loss L = BS_TXPWR - AV_RXLEV_DL
BS_TXPWR is transmission power of the carrierwhere occupied timeslot locates. It dependson the carrier’s maximum transmission power,static attenuation power, and power control.AV_RXLEV_DL is the downlink-receiving level.
Therefore, forced handover shall meet thefollowing requirements:
� Level of the destination cell must be higherthan that of the local cell by MaxLevDiff;
� Available resource of destination cell mustbe higher than transfer reserved resourcethreshold HoForceResThs;
� Path loss L must be less than MaxLossThs,and TA must be less than MaxTAThs;

Number that measurement value allowed to bezero (ZeroAllowed3G)
Full name Number that measurement value allowed to be zero
Abbreviation ZeroAllowed3G
3GPP Name None
3GPP reference None
Description
According to GSM specifications, MS can report toBSS the measurement data of at most six adjacentcells with strongest signal strength. Thus themeasurement results might not be consecutive. Forcells whose signal strength is less than -110 dBm,the measurement data are not reported.
This parameter gives flexibility in measurementdata averaging. However, excessive occurrencesof zero indicate that the adjacent cells are of poorsignal strength. If the number of zeroes in used foraverage calculation exceeds Number of zero allowedin AV, then measurement average equals to sum ofreported values divided by Neighboring cell .
To be specific, during averaging, if the count of0s in the sampling count exceeds “ZeroAllowed”,these sampling values are hardly reliable, andthe measurement average will be the sum ofthe reported values divided by NCellWindow. Ifthe count of 0s in the reported values does notexceed “ZeroAllowed”, these sampling valuesare much reliable and the measurement averagewill be the sum of the reported values dividedby (NCellWindow – the count of 0s).

Description
MS in single-frequency GSM system needsonly to report contents of six adjacent cellswith the strongest signals in a frequencyband, when reporting the survey result ofadjacent cells to the network.
In multi-band networking, MS can enter with priorityinto a specific frequency band during handover.The MS reports the survey result according to thesignal intensity and the frequency band of thesignals, according to the actual situation.
MulBndRprtPS is used to notify MS to report contentsof adjacent cells in multiple frequency bands. Itis one of the system control parameters.
The setting of this parameter is subject to trafficin each frequency band. General principles to setthe parameters are as follows: 0: If the traffic ofeach frequency band is almost equivalent, and theoperator has no choice over the frequency band.3: If the traffic of each frequency band is quitedifferent, and the operator hopes that MS entersa specific frequency band with priority.

Chapter 5 Cell Object Parameters
3GPP reference 3GPP TS 45.008 V5.22.0
Description
This parameter defines the minimum receivingintensity level (on BCCH) required for MS tohandover to this cell. It is one of parameters todecide preferred cells during handover control. MSin the serving cell constantly monitors the signalintensity on BCCH of adjacent cells. Adjacentcells with the minimum receiving intensity levelhigher than this parameter are potential candidatesfor handover. MS with receiving level largerthan minimum receiving level indicates that MSis at the edge of the serving cell.
Recommended value is usually approximatedaccording to MS receiving sensitivity. When networkobserves uneven traffic distribution in certain cells,MIN access level increases the resulting C1 andC2 to decrease the cell effective coverage range.However, the value of this parameter cannot be toolarge. Otherwise, large value change can bring ‘voidarea’ across cell boundaries to result in sudden calldrop problem. With this measure for traffic balance,it is suggested that the level value shall not exceed-90dB. At the preliminary running stage of thenetwork, this parameter can be usually set as 10(that is, -101 dBm ~ -100 dBm) or lower, which ishigher than the MS receiving sensitivity –102 dBm.However, when the network capacity is expanded orthe radio coverage in a cell is not a problem, thisparameter of the cell can be increased by 2 (dB).

Description
This parameter provides the handover policies inmulti-layer network technology and dual-frequencynetwork technology. Multi-layer radio coveragecan be formed in the same physical area.
The handover policies will not be detailed in thismanual. In brief, limiting the PBGT handoverdefined in the specifications at one layer can reducethe number of handovers during the call, thusimproving the system reliability and communicationquality. The policy of handover between a macrocell layer and a micro cell layer mainly depends onthe moving speed of MS. An MS at higher movingspeed will try to stay at the macro cell layer (upperlayer of the micro cell layer), and an MS at lowermoving speed will try to enter the micro cell layer(lower layer of the macro cell layer). Only in caseof PBGT handover and handover towards undefinedlayer being allowed will the undefined cell of theservice area be considered as a candidate cell.
"Same layer of the home cell": Adjacent cell andlocal cell are in the same layer (PBGT handoveris possible). "Upper layer of the home cell":Adjacent cell is the upper layer of local cell (whenthe local cell is a micro cell). "Lower layer of thehome cell": Adjacent cell is the lower layer oflocal cell (when the local cell is a macro cell).For details, refer to Appendix.

Neighboring cell layer (NCellLayer)
Full name Neighboring cell layer

3GPP Name None

Description
This parameter provides the handover policies inmultilayer network technology and dual-frequencynetwork technology. Multilayer radio coverage canbe formed in the same physical area.
The handover policies will not be detailed in thismanual. In brief, limiting the PBGT handoverdefined in the specifications at one layer can reducethe number of handovers during the call, thusimproving the system reliability and communicationquality. The policy of handover between a macrocell layer and a micro cell layer mainly depends onthe moving speed of MS. An MS at higher movingspeed will try to stay at the macro cell layer (upperlayer of the micro cell layer), and an MS at lowermoving speed will try to enter the micro cell layer(lower layer of the macro cell layer). Only in caseof PBGT handover and handover towards undefinedlayer being allowed will the undefined cell of theservice area be considered as a candidate cell.
"Same layer of the home cell": Adjacent cell andlocal cell are in the same layer (PBGT handoveris possible). "Upper layer of the home cell":Adjacent cell is the upper layer of local cell (whenthe local cell is a micro cell). "Lower layer of thehome cell": Adjacent cell is the lower layer oflocal cell (when the local cell is a macro cell).For details, refer to Appendix.

Hopping sequence No. (HSN)
Full name Hopping sequence No.
Abbreviation HSN
3GPP Name Hopping sequence number
3GPP reference 3GPP TS 44.018 V5.22.0
Description
According to GSM 05.02 Frequency HopingAlgorithm, MAI is a function of TDMA Framenumber (FN), Hoping Sequence Number (HSN)and Mobile Allocation Index Offset (MAIO). HSNdetermines the operation track of frequenciesduring the frequency hopping process. Usingdifferent HSN for cells having same MA can avoidfrequency utilization conflict between adjacent cellsduring the frequency hopping process.
Different timeslots can share the same group of MAand corresponding HSN. When HSN = 0, it is a specialfrequency hopping (i.e. circular frequency hopping)
HSN can be derived from BCC of the cell, becausecells using the same MA also have the same BCCH.
For example, if HSN ∈ [(BCC×6)+1, (BCC×6)+6],then each cell may use any of the 6 HSNs. Theremaining 0 and 49 ~ 63 are used in otherspecial cases. For simple implementation,directly use 0 by default.
