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.

Description

This parameter is used to control open loop uplinkpower control. MS uses Γ CH parameter forcalculating uplink transmission power, based on thefollowing formula:Γ CH = Γ 0 – PBTS - SSb –48

This parameter decides the SSb parameter.

Full name Power descending of PDCH to BCCH in A mode

Abbreviation P0

3GPP Name P0


Description

This parameter is an optional downlink powercontrol parameter contained in assignmentmessage. MS uses power control if this parameterexists. During the packet transmission mode, P0value shall not be changed unless re-assignment ornew assignment is established and the assignmentdoes not contain the PDCH(s) of any previousassignment.

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)


Value Range 0 ~ 31

Unit None

Full name Uplink power level

Abbreviation HoUlLevWindow

3GPP Name N1..N8,P1..P8



68/817



Description

In GSM system, BSC uses the power levelmeasurement data to manage and controlhandover decisions. BSC uses average valuesinstead of original values of measurement data forhandover decisions. It helps prevent negativeimpact on network performance caused by abruptchanges in measurement data.This parameter is the window size (number ofsample values) used to calculate average value ofuplink signal intensity.


Value Range 1 ~ 31

Unit None

Default 4

Description

Speech data is unavailable for silent period duringconversation. GSM specifications recommendDiscontinuous Transmission Mode (DTX) to controloptimal usage of network resources during suchsilent periods.BTS reports two types of measurement data to BSCwhen using DTX mode. 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
