Measurement Counter
CH340:CELL_INTERBSC_INCELL_HO_REQ
Description
BSC determines whether to initiate the handover from the originating cell to the target cell through the handover algorithm. If the originating cell and the target cell are controlled by different BSCs, the external inter-cell handover is initiated.
This measurement provides the number of incoming external inter-cell handover requests. The measurement object is the target cell.
Unit
Integer number or integer.
Measurement Point
As shown in Figure 1, the counter is measured at A when the target BSC (BSC2) receives the HO REQ message from the MSC. The measurement object is the target cell.
