Unsuccessful VGCS Uplink Seizures (MSC Rejected)

Measurement Counter

A03445: CELL_UL_REQ_FAIL_MSC_REJ

Description

During the request of an MS for the uplink TCH, when the BSC sends an UPLINK REQUEST message to the MSC, other BSCs may simutaneously send UPLINK REQUEST messages to the MSC. Therefore, the MS is not assigned an uplink TCH and the MSC sends an UPLINK REJECT COMMAND message to the BSC after decision. That is, the request of the MS for the uplink TCH is rejected by the MSC. This measurement provides the number of requests for the uplink TCH rejected by the MSC.

Unit

Integer number or integer.

Measurement Point

This counter is incremented by one when the BSC receives an UPLINK REJECT COMMAND message from the MSC. In the signaling procedure, this counter is measured at point C in Figure 1.
