Failed Incoming Internal Inter-Cell Handovers (Timer Expired)

Measurement Counter

CH322C:CELL_INTRABSC_INCELL_HO_FAIL_TIMEOUR

Description

During the incoming internal inter-cell handover procedure, the timer T3103 starts after the BSC sends the HO CMD to the MS. This counter provides the number of failed incoming internal inter-cell handovers due to the expiration of T3103, including those on the signaling channels (SDCCH/TCHF/TCHH) and traffic channels (TCHF/TCHH).

Unit

Integer number or integer.

Measurement Point

As shown in Figure 1, during the incoming internal inter-cell handover procedure, this counter is measured at E when the T3103 expires after the BSC sends the HO CMD to the MS.
