参考答案:
通过Source eNodeB侧counter统计S1接口接收到的cause为successful handover的UE Context Release Command,X2接口接收到的UE Context Release次数,以及eNodeB向UE发送的Handover Command(RRCConnectionReconfiguration including mobilityControlInfo)次数。
Handover Success Rate = Number_Of_Successful_HO / Number_Of_HO_Attempt * 100%
其中Number_Of_Successful_HO就是S1接口接收到的cause为successful handover的UE Context Release Command的次数和X2接口接收到的UE Context Release次数之和。
Number_Of_HO_Attempt就是eNodeB向UE发送的Handover Command(RRCConnectionReconfiguration including mobilityControlInfo)的次数。
