L9412: CELL_LLC_TX_UP_EGPRS_STRM_LLC_PDU_TOTAL_BYTE
This measurement provides the total bytes of uplink EGPRS streaming service LLC PDUs in a granularity period.
byte.
In a granularity period, every time the BSC sends an UPLINK LLC PDU to the SGSN (see measurement point A in Figure 1), the bytes of the UPLINK LLC PDU are accumulated to the value of the counter, provided that the TBF is an EGPRS TBF and guarantees the valid bandwidth.
This is an original counter without involving any formula.
