Attempted VGCS TCH Handovers for Better Cell

Measurement Counter

A03503: CELL_GCC_HO_REQ_BETTER_CELL

Description

After the originating BSC makes the handover decision, the originating BSC analyzes the reason for the handover. This measurement provides the number of handovers for better cell. Along with Successful VGCS TCH Handovers for Better Cell, this measurement reflects the performance of the handovers for better cell.

Unit

Integer number or integer.

Measurement Point

The measurement point is specified in the following three situations:

(1) In the case of the intra-cell handover, this counter is incremented by one when the originating BSC sends a HANDOVER REQUIRED message to the MSC for better cell. The measurement point is A, as shown in Figure 1.
(2) In the case of the inter-cell handover, this counter is incremented by one when the BSC determines to initiate the internal inter-cell handover based on the measurement report for better cell. The measurement point is A, as shown in Figure 2.
(3) In the case of the inter-BSC handover, this counter is incremented by one when the originating BSC sends a HANDOVER_REQUIRD message to the MSC for better cell. The measurement point is A, as shown in Figure 3.
