1.4 切换类指标

BSC实现互联（软切换）：

源BSS内切换统计

1、 切换成功次数（统计点1）： 源BS收到终端发送的“Handoff Completion Message”，上报源BSS

“切换成功次数”一次；

2、 切换失败次数：当目标侧切换失败或者源侧切换判决失败或者移动台切换超时，上报源BSS内

“切换失败次数”一次； 目标BSS内切换统计

1、 切换成功次数（统计点2）： 源BS收到目标BS发送的“A7 handoff request Ack”，上报目标BSS

内“切换成功次数”一次；

2、 切换失败次数：当跨BSS切换失败，目标BSS向源侧发送切换请求应答（A7 handoff request ）

消息时，上报目标BSS内 “切换失败次数”统计 注：

1、 BSS只统计切换加，不统计切换去，因为切换去肯定能成功。

2、 硬切换，包括换频切换、换RC切换、换FO切换，统计点和统计方法跟软切换相同。 3、 切换请求次数 = 切换成功次数+切换失败次数

BSC间未互联（硬切换）： 源侧切换去：

1、 切换去请求次数（统计点1）：源BS向MSC发送“Handoff Required”，上报 “切换去请求次数”

一次。
