1、eNB间S1切换出请求次数:
源eNB向MME发送的“切换请求”消息(HANDOVERREQUIRED)(3GPPTS36.413),指示eNB间通过S1接口的切换出准备请求。
向不同小区发送的同一切换准备请求,需要重复统计。
2、eNB间S1切换出成功次数:
源eNB收到MME发送的“UE上下文释放命令”消息(UECONTEXTRELEASECOMMAND)(3GPPTS36.413),指示eNB间通过S1接口的切换出执行成功。
3、eNB间X2切换出请求次数:
源eNB向目标eNB发送的“切换请求”消息(HANDOVERREQUEST)(3GPPTS36.423),指示eNB间通过X2接口的切换出准备请求。
向不同小区发送的同一切换准备请求,重复统计。
4、eNB间X2切换出成功次数:
源eNB收到目标eNB发送的“UE上下文释放”消息(UECONTEXTRELEASE)(3GPPTS36.423),指示eNB间通过X2接口的切换出执行成功。
5、eNB内切换出请求次数:
eNB向UE发送携带mobilityControlInfo的“RRC连接重配置”消息(RRCConnectionReconfiguration),指示eNB内小区间切换出请求。
(3GPPTS36.331)
6、eNB内切换出成功次数:
eNB收到UE发送的“RRC连接重配置完成”消息(RRCConnectionReconfigurationComplete),指示eNB内小区间切换出成功。
