Failed Outgoing Inter-RAT Inter-Cell Handovers (Clear Commands Sent By MSC)

Measurement Counter

CH352H:CELL_INTERRAN_OUTCELL_HO_FAIL_MSC_CLR

Description

This counter provides the number of failed outgoing inter-RAT inter-cell handovers because the BSC receives a CLEAR CMD message from the MSC and the Cause is not Handover successful. The Cause contained in the CLEAR CMD message can be:

Radio interface message failure
Radio interface failure
OM intervention
Equipment failure
Preemption
Invalid message
Protocol error between BSS and MSC
Other causes

Unit

Integer number or integer.

Measurement Point

At point E, as shown in Figure 1 and Figure 2, the counter is measured when the BSC receives the CLEAR CMD message from the MSC and the Cause is not Handover successful.

Figure 1 Measurement of the counters related to failed outgoing inter-RAT inter-cell handover (excluding directed retry)

Figure 2 Measurement of the counters related to failed outgoing inter-RAT inter-cell handover (directed retry)
