Number of Inter-BSC Outgoing Cell Handover Successes During BTS Loopback

Measurement Counter

CH333b:CELL_INTERBSC_OUTCELL_HO_SUCC_BTS_LOOP

Description

This measurement provides the total number of inter-BSC outgoing cell handover successes during BTS loopback. The counter is calculated by subtracting the Number of Inter-BSC Outgoing Cell Handover Failures During BTS Loopback from the Number of Inter-BSC Outgoing Cell Handover Requests During BTS Loopback.

Unit

Integer number or integer.

Measurement Point

As shown in Figure 1 and Figure 2, the counter is measured at C when the BSC receives the CLEAR CMD message from the MSC during the outgoing external inter-cell handover and the cause carried in the CLEAR CMD message is Handover successful (0x0B).

Formula

Number of Inter-BSC Outgoing Cell Handover Successes During BTS Loopback = [Number of Inter-BSC Outgoing Cell Handover Requests During BTS Loopback] - [Number of Inter-BSC Outgoing Cell Handover Failures During BTS Loopback]
