Attempted Handovers per BSC (Rapid Level Drop)

Measurement Counter

ZCH970H:BSCRPT_HO_REQ_RAPID_LEV_DROP

Description

This measurement provides the number of outgoing inter-cell handover requests of all the cells controlled by a BSC due to rapid level drop, including outgoing internal cell handover requests and outgoing external inter-cell handover requests.

The BSC uses the handover algorithm to decide whether a handover is required based on the measurement reports submitted by the MS. If a handover is required, and if the source cell (current cell) and the target cell are two different cells controlled by one BSC, the BSC initiates an internal inter-cell handover. If the handover cause value is rapid level drop, the BSC measures the number of outgoing internal inter-cell handover requests due to the rapid level drop in the source cell. If the source cell (current cell) and the target cell are two different cells controlled by different BSCs, the BSC initiates an external inter-cell handover. If the handover cause value is rapid level drop, the BSC measures the number of outgoing external inter-cell handover requests due to the rapid level drop in the source cell.

Unit

Integer number or integer.

Measurement Point

This counter is measured according to the following formula when the measurement period ends. For details on the measurement point, see "Measurement Point" of each counter in the formula.

Formula

Attempted Handovers per BSC (Rapid Level Drop) = Outgoing Internal Inter-Cell Handover Requests (Rapid Level Drop) + Outgoing External Inter-Cell Handover Requests (Rapid Level Drop)
