S4348D:TRX_HR_DROP_TA
After receiving a valid MR or pre-processed MR, the BSC takes statistics of some parameter values based on the requirements. The statistics can help users better understand the network performance. The measurement provides the accumulated TA value reported by the MRs during the radio link failure on the TCHH. This counter is used to calculate the counter AS4348D: TRX_HR_DROP_TA_AVR.
TA.
In the granularity period, this counter is incremented by the TA value in the last valid MR or pre-processed MR before the radio link failure occurs on the TCHH.
This is an original counter without involving any formula.
