Parameter Name Meaning Feature Name Actual Value Range

FDD Qmin

This parameter specifies one of the parameters for FDD cell reselection. A FDD cell becomes a candidate cell if all the following conditions are met for five consecutive seconds: 1.Receive level of the FDD cell > Average receive level of the current serving cell + "FDD Q offset";The FDD cell meets the following condition in the case of any neighboring 2G cell: Receive level of the FDD cell > Receive level of any neighboring 2G cell + "FDD Q offset";2. Ec/No of the FDD cell > "FDD Qmin" - "FDD Qmin Offset";3. Receive level of the FDD cell > "RSCP Threshold";If multiple FDD cells meet the preceding conditions, the MS reselects the cell with the strongest receive level. See 3GPP TSs 45.008 and 25.304.The values of this parameter correspond to the following decibel values: 0: -20 dB,1: -6 dB,2: -18 dB,3: -8 dB,4: -16 dB,5: -10 dB,6: -14 dB,7: -12 dB.

FDD Q Offset

This parameter specifies one of the thresholds of the signal level for 3G cell reselection.A FDD cell becomes a candidate cell if all the following conditions are met for five consecutive seconds: 1.Receive level of the FDD cell > Average receive level of the current serving cell + "FDD Q offset";The FDD cell meets the following condition in the case of any neighboring 2G cell: Receive level of the FDD cell > Receive level of any neighboring 2G cell + "FDD Q offset";2. Ec/No of the FDD cell > "FDD Qmin" - "FDD Qmin Offset";3. Receive level of the FDD cell > "RSCP Threshold";If multiple FDD cells meet the preceding conditions, the MS reselects the cell with the strongest receive level. See 3GPP TSs 45.008 and 25.304.The values of this parameter correspond to the following decibel values:0: - (always select a cell if acceptable)1: -28 dB,2: -24 dB,...15: 28 dB.

SET GCELLCCUTRANSYS(Optional)

the level threshold for cell reselection in idle mode. In idle mode, if the signal level of the serving cell is below [0, 7] or above [8, 15], the MS starts to search for 3G cells. For example, if this parameter is set to 5 and if the signal level of the serving cell is lower than 5, the MS starts to search for 3G cells; if this parameter is set to 10 and if the signal level of the serving cell is above 10, then the MS starts to search for 3G cells. The values of this parameter correspond to the following decibel values: 0: -98 dBm1: -94 dBm 2: -90 dBm3: -86 dBm 4: -82 dBm

Qsearch P BSC6900

SET GCELLCCUTRANSYS(Optional)

This parameter specifies one threshold of the signal level for cell reselection in packet transfer mode. In packet transfer mode, if the signal level of the serving cell is below [0, 7] or above [8, 15], the MS starts to search for 3G cells. For example, if this parameter is set to 5 and if the signal level of the serving cell is lower than 5, the MS starts to search for 3G cells; if this parameter is set to 10 and if the signal level of the serving cell is above 10, then the MS starts to search for 3G cells. The values of this parameter correspond to the following decibel values: 0: -98 dBm 1: -94 dBm

FDD Qmin Offset BSC6900

SET GCELLCCUTRANSYS(Optional)

Offset of the minimum threshold for Ec/No during a FDD cell reselection.A FDD cell becomes a candidate cell if all the following conditions are met for five consecutive seconds: 1.Receive level of the FDD cell > Average receive level of the current serving cell + "FDD Q offset";The FDD cell meets the following condition in the case of any neighboring 2G cell: Receive level of the FDD cell > Receive level of any neighboring 2G cell + "FDD Q offset";2. Ec/No of the FDD cell > "FDD Qmin" - "FDD Qmin Offset";3. Receive level of the FDD cell > "RSCP Threshold";If multiple FDD cells meet the preceding conditions, the MS reselects the cell with the strongest receive level. See 3GPP TSs 45.008 and 25.304.
