In the immediate assignment, assignment, or handover procedure, the BTS sends the MR or pre-processed MR over the SDCCH/TCH to the BSC. Based on the Huawei II channel assignment algorithm, the BSC compares the uplink/downlink level and quality in the MR with the Uplink/Downlink Interference Level Threshold and Uplink/Downlink Interference Quality Threshold in data configuration to determine whether to measure the four counters Uplink/Downlink Interference Indication Messages (SDCCH/TCH). If both the level and the quality exceed the thresholds, the BSC measures the specific counter based on the channel type (TCH or SDCCH), and the interference direction (uplink or downlink).
Integer number or integer.
In the immediate assignment procedure, after receiving the EST IND message from the BTS, the BSC starts to receive the MR or pre-processed MR over the SDCCH. If the uplink/downlin level and quality in the MR sent from the MS both exceed the Uplink/Downlink Interference Level Threshold and Uplink/Downlink Interference Quality Threshold in data configuration, the BSC measures S4210A: TRX_CH_UP_INTFR_IND_NUM_SD and S4210B: TRX_CH_DOWN_INTFR_IND_NUM_SD respectively based on the interference direction (uplink or downlink).
In the assignment or handover procedure, after receiving the EST IND message from the BTS, the BSC starts to receive the MR or pre-processed MR over the TCH. If the uplink/downlin level and quality in the MR sent from the MS both exceed the Uplink/Downlink Interference Level Threshold and Uplink/Downlink Interference Quality Threshold in data configuration, the BSC measures S4219A: TRX_CH_UP_INTFR_IND_NUM_TCH and S4219B: TRX_CH_DOWN_INTFR_IND_NUM_TCH respectively based on the interference direction (uplink or downlink).
This is an original counter without involving any formula.
