Number of Downlink GPRS TBF Abnormal Releases due to other cause

Measurement Counter

A9117:DOWN_GPRS_TBF_ABNORM_REL_OTHER_CAUSE

Description

This measurement provides the number of downlink GPRS TBF abnormal releases due to other causes in a granularity period. A high measurement value is yielded because the parameter is incorrect, the number of downlink GPRS TBFs on the PDCH reaches the limit, or the cell is manually blocked. Refer to device alarms to locate the cause.

Unit

Integer number or integer.

Measurement Point

If the cause is parameter error, flow control, or manual cell blocking, the BSC releases the channel resources irrespective of the MS status. The downlink GPRS TBF that uses the channel as the control channel is also released. Figure 1 shows the procedure of downlink GPRS TBF abnormal release due to other causes. Each time the BSC abnormally releases the downlink GPRS TBF that uses the channel as the control channel due to other causes (see measurement point A), the counter is incremented by one.
