Measurement Counter
H312OI: CELL_INBSC_OUT_CELL_HO_FAIL_ULCELL_OLCELL
Description
When a handover between different concentric cells is performed under the same BSC, the performance of the handover is measured. Taking the originating cell as the measurement object, this measurement provides the number of unsuccessful handovers from the underlaid subcell of the originating cell to the overlaid subcell of the target cell. The handovers involve the handover between traffic channels, handover between signaling channels, and directed retry.
Unit
Integer number or integer.
Measurement Point
As shown in Figure 1, after receiving an MR from the MS, the BSC initiates a handover from the underlaid subcell of the originating cell to the overlaid subcell of the target cell. This counter is measured at C when the timer waiting for a Handover CMP message expires, or at D when the BSC receives a Ho Fail message.
Formula
This is an original counter without involving any formula.
