Description
This parameter defines combined types of timeslot channel. Correlation with the following several parameters is as follows:
CBC supported (SmsCbUsed).
If "CBC Supported (SmsCbUsed)" is No, that is, CBC is not supported, the system automatically final all timeslot channel combinations in the cell.If CBC channel exists, it is changed to SDCCH.
If "CBC Supported (SmsCbUsed)" is Yes, that is, CBC is supported, the system automatically find all timeslot channel combinations in the cell.If a non-BCCH channel is found for a carrier, it is changed to SDCCH+CBCH.
GPRS service supported (PsSupport)
If "GPRS Supported (PsSupport)" is No, that is, GPRS is not supported, the system automatically change all timeslot channels whose type is PS in the cell to TCH.
Common control channel configuration (CcchConf)
When CCCH Channel (CcchConf) is configured as "a basic physical channel used by CCCH, along with SDCCH". In channel information parameters, timeslot 0 channel combination shall be one of these two combined channels: BCCH+SDCCH/4 and BCCH+SDCCH/4+CBCH.

3GPP Name Mobile Allocation Index Offset
3GPP reference
3GPP TS 44.018 V5.22.0
Description
During communication, the carrier number adopted on air interface is an element of the MA set. Mobile Allocation Index (MAI) (0 MAI n-1) is a variable for determining a definite element in the MA set. According to the FH algorithm in GSM 05.02 specification, MAI is function of the following aspects: TDMA Frame Number (FN) or Reduced TDMA Frame Number (RFN), frequency Hopping Serial Number (HSN), and Mobile Allocation Index Offset (MAIO). MAIO is an initial offset of MAI and is used for preventing several channels to contend for the same carrier at the same moment. Generally, several basic FH units (timeslot or TDMA frame) constitute an FH group. They have the same MA and HSN and the only difference among them is MAIO. Thus the same MA and HSN are put in FHS/MA table. When the FH group corresponding to the timeslot has no frequency hopping, MAIO of the timeslot is invalid.

Description
Speech data is unavailable for silent period during conversation. GSM specifications recommend Discontinuous Transmission Mode (DTX) to control optimal usage of network resources during such silent periods.
BTS reports two types of measurement data to BSC when using DTX mode. One is the average value of measurement results of all timeslots within a measurement period in non-DTX mode. The other is the average value of measurement results of some specific timeslots within a measurement period in DTX mode. BSC selects one type of measurement data according to the actual situation for calculating the average value.
The first type of measurement data is more accurate since it is the average value of measurement results of all timeslots. The second type of measurement data is less accurate since it is the average value of measurement results of some timeslots. Thus BSC should use different weights for the two types of data when averaging the measurement results.
This parameter determines the weight for the first type of measurement data when averaging uplink signal strength for power control. Weight for the second type of measurement data is set to 1 by default.

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. During BSC power control, this parameter determines the maximum transmission power available for MS in the cell. BSC also uses it to calculate PBGT value.

Description
This parameter specifies the minimum interval of power control. Usually, MS still sends two measurement reports with the original power to BSC after enabling the power control. Signal level information contained in the reports is inaccurate and can be ignored (information such as adjacent cell information is still valid). Thus a minimum interval of power control is needed and signal level information during the interval can be ignored.

Description
According to GSM specifications, MS can report to BSS the measurement data of at most six adjacent cells with strongest signal strength. Thus the measurement results might not be consecutive. For cells whose signal strength is less than -110 dBm, the measurement data are not reported. BSC marks measurement data of such adjacent cells as zero.
This parameter gives flexibility in measurement data averaging. However, excessive occurrences of zero indicate that the adjacent cells are of poor signal strength.
If the number of zeroes in used for average calculation exceeds Number of zero allowed in AV, then measurement average equals to sum of reported values divided by Neighboring cell .
If the number of zeroes in used for average calculation does not exceed Number of zero allowed in AV, then the measurement average equals to sum of reported values divided by (Neighboring cell - number of zeroes)

56 Confidential and Proprietary Information of ZTE CORPORATION
Description
Speech data is unavailable for silent period during conversation. GSM specifications recommend Discontinuous Transmission Mode (DTX) to control optimal usage of network resources during such silent periods.
BTS reports two types of measurement data to BSC when using DTX mode. One is the average value of measurement results of all timeslots within a measurement period in non-DTX mode. The other is the average value of measurement results of some specific timeslots within a measurement period in DTX mode. BSC selects one type of measurement data according to the actual situation for calculating the average value.
The first type of measurement data is more accurate since it is the average value of measurement results of all timeslots. The second type of measurement data is less accurate since it is the average value of measurement results of some timeslots. Thus BSC should use different weights for the two types of data when averaging the measurement results.
This parameter determines the weight for the first type of measurement data when averaging uplink signal strength for handover. Weight for the second type of measurement data is set to 1 by default.
