This measurement provides the total bytes of downlink EGPRS streaming service LLC PDUs in a granularity period.
byte.
Figure 1 shows the procedure in which the BSC checks the received PACKET DOWNLINK ACK/NACK message to determine whether the DOWNLINK LLC PDU is successfully sent to the MS. Each time a DOWNLINK LLC PDU is successfully sent and then deleted from the PDU sending queue (see measurement point A), the bytes of the DOWNLINK LLC PDU are accumulated to the counter. The TBF is a EGPRS TBF that supports bandwidth guarantee.
This is an original counter without involving any formula.
