1、掉话类故障处理指导掉话分类定义在华为Probe侧对于掉话(ERABAbnormalRelease)的定义：UE没有收到DeactivateEpsBearerContextRequest消息,但收到RRCRelease或RRCConnectionReconfiguration消息,则表示ERAB异常释放。标口信令eNodeB跟踪到的标准接口信令中，如果存在eNodeB发起的释放，即在S2接口上发往CN的S1AP_UE_CONTEXT_REL_REQ消息内携带的原因值不为“User-inactivity(20)”时，则判断为掉话。掉话预检查方式异常掉话通常都是由eNB发起的释放，通知MME

2、释放上下文，因此只要查看S1口发送的S1AP_UE_CONTEXT_REL_REQ消息即可，如下图所示。1092010-10-0410:2604(2596181)SIAP.UE.CONTEXr.REL.REOSEND2010-10-0410:26.04(266718pr201010-0410:2604(2671292010-10-04102607(5395311132010-10-0410:26:07(546216p201010-0410:26.07(568834vT2010-10.04102607(572842[fT2010-10-0410:26.07(5748472010-1004
