Failed Outgoing Internal Inter-Cell Handovers (Timer Expired)

Measurement Counter

CH312C:CELL_INTRABSC_OUTCELL_HO_FAIL_EXP

Description

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

Unit

Integer number or integer.

Measurement Point

As shown in Figure 1 and Figure 2, during the outgoing internal inter-cell handover procedure, the counter is measured at E when T3103 expires after the BSC sends the HO CMD to the MS.
