这里列举了3种失败第一种是ENB没有开启重建允许开第二种是终端上发的C-RNTI号eNB不认识，即终端在非原来的eNB上发起重第三种是ENB允许重建，下发了RRCConnectionReestablishment，但在计时器超时后仍没有收到终端的响应这里列举了2类失败第一种是ENB下发RRCConnectionReconfiguration后在计时器超时后仍未收到终端上发的RRCConnectionReconfigurationcomplete消息。这种情况可能是无线问题或者是终端问题第二种是在一个正在进行的重新建立过程完成以前，eNodeB接收到另外一个来自相同UERrcConnectionReestablishmentRequest，这种情况终端问题可能性较RR边路这里列举了2MAC-I=MessageAuthenticationCode这里列举了2Integrityprotection(atPDCPlevel)isrealizedbyaddingafieldknownasMAC-ItoeachRRC一类是UEShortMAC-IUEeNBShortMAC-I不匹配，这属于终端或APDCPentityisassociatedwiththeControlPlaneandtheUserPlane.EachradiobearerisassociatedonePD重ntity，.正好对

这种情况就是起始上下文建立失败E-RAB上下文建立分配错误，即ENB上发InitialUEMessage消息后，在计时器规定时间内没有收到MME下发的INITIALCONTEXTSETUPREQUEST消息。因此在计时器超时后，ENB向MME发送UecontextreleaseRequest消息来UE上下文E文L250计MM1ee第二种是ENB检查出S1存在故这两种情况，ENB都会本地UE上下文，不会存在与MME交互的UecontextreleaseRequest与Uecontextreleasecommand，因此存在计数器LC12509来统计这类本地次数EeMbtERACa计时器，等待重定向成功后，MMEUecontextreleasecommand消息，若计时器超时仍未收到的话，第二个是E重定向到另外一个载频的场景。当eB收到终端上报的测量报告，需要触发重定向到其他载频时，向终端发送RoeReae消息，该消息包含了重定向的载频信息。EB下发该消息的同时，向ME发送Ueteeases，E125012502:Re-establishmentissuccessfullyperformedwhenintereNodeBoverS1handoverprocedureisongoing3:Re-establishmentissuccessfullyperformedwhenhandoverprocedureisongoing;theThecellonwhichthere-establishmentisperformedisnotthecell(oftheHOprocedure)4:Re-establishmentissuccessfullyperformedbutthereisnohandoverprocedureongoingwhenrequestforre-establishmentisreceived.Thecellonwhichthere-establishmentisrequestedisnottheservingcell.5:Re-establishmentissuccessfullyperformedonservingcellandthereisnohandoverprocedureongoing.6:Re-establishmentissuccessfullyperformedwhenintraeNodeBinter-frequencyhandoverprocedureisongoing.Thecellonwhichthere-establishmentisrequestedisthecell.7:Re-establishmentissuccessfullyperformedwhenintereNodeBinter-frequencysameframestructure(TDDorFDD)handoveroverX2procedureisongoing.Thecellonwhichthere-establishmentisrequestedisthecell.8:Re-establishmentissuccessfullyperformedwhenintereNodeBinter-frequencysameframestructure(TDDorFDD)handoveroverS1procedureisongoing.Thecellonwhichthere-establishmentisrequestedisthecell.9:Re-establishmentissuccessfullyperformedwhenintereNodeBinter-frequencyotherframestructure(TDD<>FDD)handoveroverX2procedureisongoing.Thecellonwhichthere-establishmentisrequestedisthecell.10:Re-establishmentissuccessfullyperformedwhenintereNodeBinter-frequencyotherframe(TDD<>FDD)structurehandoveroverS1procedureisongoing.Thecellonwhichthere-establishmentisrequestedisthecell.11:Re-establishmentissuccessfullyperformedwhen
