A03425: CELL_VBS_ASS_FAIL
Description
After the BSC receives the VBS ASSIGNMENT REQUEST message from the MSC, the BSC may fail to assign TCHs. If the assignment fails, the BSC sends a VBS ASSIGNMENT FAILURE message to the MSC. This measurement provides the number of VBS ASSIGNMENT FAILURE messages that the BSC sends to the MSC.
Unit
Integer number or integer.
Measurement Point
This counter is incremented by one when the BSC sends a VBS ASSIGNMENT FAILURE message to the MSC. In the signaling procedure, this counter is measured at point A in Figure 1.
Formula
This is an original counter without involving any formula.
