Handover Success Rate

This statistic provides the percentage of handovers that wereattempted from the source cell (the cell for which This statistic ispresented), that successfully reached the target cell, and

returned to the source cell successfully. A handover attempt is

counted when a handover command is sent to the MS. This keystatistic includes inter-BSC Handovers.

Congestion on the target cell does not result in the BSS sendinga handover command to the mobile. Therefore this

measurement is not impacted by target cell congestion.

Handover success rate equals to the number of handoversuccess divided by the number of handover requests.
