cause分析
102
Recovery on
timer expiry(定时器超时恢复)
This cause indicates that a procedure has been initiated by the
expiration of a timer in association with error handling
procedures.
What it means:This is seen in situations where ACO (Alternate Call
Offering) is being used. With this type of call pre-emption, the
Telco switch operates a timer. For example, when an analog call is
placed to a Netopia router that has two B Data Channels in place,
the router relinquishes the second channel, but if it doesn't
happen in the time allotted by the switch programming, the call
will not ring through and will be discarded by the switch.
这个应该为超时为响应。以我的经验来看,这个应该是用户当时占用的时隙出了问题。建议核查传输。
这个原因是定时器到时恢复,一般都是没有接通的通话流程。也就是寻呼之后用户应答,网络自动断连。不是掉话。
建议检查disconnect信令前是否还存在nas的信令,从disconnect消息看应该是NAS的定时器超时导致释放CC连接的。
异系统切换导致信令丢失,网络端向UE下发disconnect消息
未接通的因素有:被叫位置更新、无线网络质量差
/ 过覆盖/ 弱覆盖、TCH拥塞、硬件故障、Paging
Delete、被叫频繁的小区重选、呼叫重建失败、上行干扰等八类原因
