combinations in the cell.If CBC channelexists, it is changed to SDCCH.
If "CBC Supported (SmsCbUsed)" is Yes,that is, CBC is supported, the systemautomatically find all timeslot channelcombinations in the cell.If a non-BCCHchannel is found for a carrier, it is changedto SDCCH+CBCH.

3GPPreference 3GPP TS 44.018 V5.22.0
Description
During communication, the carrier number adoptedon air interface is an element of the MA set. MobileAllocation Index (MAI) (0 ≤ MAI ≤ n-1) is avariable for determining a definite element in theMA set. According to the FH algorithm in GSM05.02 specification, MAI is function of the following
aspects: 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 or TDMAframe) constitute an FH group. They have the sameMA and HSN and the only difference among them isMAIO. Thus the same MA and HSN are put inFHS/MA table. When the FH group corresponding tothe timeslot has no frequency hopping, MAIO of thetimeslot is invalid.

One is the average value ofmeasurement results of all timeslots within ameasurement period in non-DTX mode. The otheris the average value of measurement results ofsome specific timeslots within a measurementperiod in DTX mode. BSC selects one type of
measurement data according to the actual situationfor calculating the average value.The first type of measurement data is moreaccurate since it is the average value ofmeasurement results of all timeslots. The secondtype of measurement data is less accurate since itis the average value of measurement results ofsome timeslots. Thus BSC should use differentweights for the two types of data when averagingthe measurement results.This parameter determines the weight for the firsttype of measurement data when averaging uplinksignal strength for power control.

This parameter specifies the minimum interval ofpower control. Usually, MS still sends twomeasurement reports with the original power toBSC after enabling the power control. Signal levelinformation contained in the reports is inaccurateand can be ignored (information such as adjacentcell information is still valid). Thus a minimuminterval of power control is needed and signal levelinformation during the interval can be ignored.

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. BSCmarks measurement data of such adjacent cells aszero.This parameter gives flexibility in measurementdata averaging. However, excessive occurrences ofzero indicate that the adjacent cells are of poorsignal strength.If the number of zeroes in used for averagecalculation exceeds Number of zero allowed in AV,then measurement average equals to sum ofreported values divided by Neighboring cell .If the number of zeroes in used for average
calculation does not exceed Number of zero allowedin AV, then the measurement average equals tosum of reported values divided by (Neighboring cell- number of zeroes)

Speech data is unavailable for silent period duringconversation.

One is the average value ofmeasurement results of all timeslots within ameasurement period in non-DTX mode. The otheris the average value of measurement results ofsome specific timeslots within a measurementperiod in DTX mode. BSC selects one type ofmeasurement data according to the actual situationfor calculating the average value.The first type of measurement data is moreaccurate since it is th
