L9B01:TRX_GABIS_PTRAU_RX_PTRAU_PACKETS
This measurement provides the number of PTRAU packets received by a TRX on the IP or HDLC network topology in a granularity period. The counter indicates the idleness of the uplink.
Integer number or integer.
The following figure shows the process where the BSC receives the uplink PTRAU packet. In a granularity period, the counter is incremented by one every time the BSC receives a PTRAU packet (see measurement point A in Figure 1).
This is an original counter without involving any formula.
