Description

This measurement provides the total bytes of sent downlink GPRS interactive service THPx LLC PDUs in a granularity period.

Unit

byte.

Measurement Point

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 the DOWNLINK LLC PDU is sent successfully (see measurement point A), the number of bytes of the DOWNLINK LLC PDU is added to the counter. The TBF is a GPRS TBF supporting interactive THP and the service type of the LLC PDU is interactive THPx. Note: THPx indicates THP1-THP3.
