Measurement Counter
ZCH970D:BSCRPT_HO_REQ_DL_RXL
Description
This measurement provides the number of outgoing inter-cell handover requests of all the cells controlled by a BSC due to downlink signal strength, 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. 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 downlink strength, the BSC measures the number of outgoing internal inter-cell handover requests due to downlink signal strength 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 downlink strength, the BSC measures the number of outgoing external inter-cell handover requests due to downlink signal strength 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 (Downlink Signal Strength) = 
Outgoing Internal Inter-Cell Handover Requests (Downlink Strength) + Outgoing External Inter-Cell
Handover Requests (Downlink Strength)
