Successful VGCS TCH Handovers for Downlink Strength

Measurement Counter

A03514: CELL_GCC_HO_SUCC_DL_RXL

Description

This measurement provides the number of successful VGCS TCH handovers caused by downlink signal strength.

Unit

Integer number or integer.

Measurement Point

(1) In the case of the intra-BSC intra-cell handover, this counter is incremented by one when the originating BSC receives a HANDOVER SUCCEEDED message from the MSC. The measurement point is B, as shown in Figure 1.

(2) In the case of the intra-BSC inter-cell handover, this counter is incremented by one when the target cell receives a HANDOVER COMPLETE message from the BTS. The measurement point is B, as shown in Figure 2.

(3) In the case of the inter-BSC handover, this counter is incremented by one when the originating BSC receives a HANDOVER SUCCEEDED message from the MSC. The measurement point is B, as shown in Figure 3.
