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

Measurement Counter

CH353a:CELL_INTERRAN_OUTCELL_HO_SUCC_BSC_LOOP

Description

This measurement provides the total number of inter-RAT outgoing cell handover successes during BSC loopback. It is calculated by subtracting the Number of Inter-System Outgoing Cell Handover Failures During BSC Loopback from the Number of Inter-System Outgoing Cell Handover Requests During BSC 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 inter-RAT inter-cell handover and the Cause is Handover successful (0x0B).

Formula

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