AS4307D:TRX_FR_DROP_UL_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 uplink level during radio link failure on full-rate TCH. The counter value is calculated based on the counters S4307D: TRX_FR_DROP_UL_LEV and S4357D: TRX_FR_DROP_TOTAL_NUM.
dBm.
In the granularity period, this counter is calculated according to the following formula.
Mean Uplink Level during Radio Link Failure (TCHF) = [Uplink Level during Radio Link Failure (TCHF)]/[Radio Link Failures (TCHF)]
