AS4327D:TRX_FR_DROP_DL_LEV_AVR
After receiving a valid MR or pre-processed MR, the BSC takes statistics of some parameter values based on the requirements. The statistical results can help users better understand the network performance. The measurement provides the mean downlink level during radio link failure on full-rate TCH. The counter value is calculated based on the counters S4327D: TRX_FR_DROP_DL_LEV and S4357D: TRX_FR_DROP_TOTAL_NUM.
dBm.
In the granularity period, this counter is calculated according to the following formula.
Mean Downlink Level during Radio Link Failure (TCHF) = [Downlink Level during Radio Link Failure (TCHF)]/[Radio Link Failures (TCHF)]
