LTE信令分析和attach信令分析流程，切换流程，
1.1.1 E-UTRAN初始附着过程
1.1.2 切换过程
部分内容如下：
说明：
1) 步骤1～5会建立RRC连接，步骤6、9会建立S1连接，完成这些过程即标志着NAS signalling connection建立完成。
2) 消息7的说明：UE刚开机第一次attach，使用的IMSI，无Identity过程；后续，如果有有效的GUTI，使用GUTI attach，核心网才会发起Identity过程（为上下行直传消息）。
3) 消息10~12的说明：如果消息9带了UE Radio Capability IE，则eNB不会发送UECapabilityEnquiry消息给UE，即没有10~12过程；否则会发送，UE上报无线能力信息后，eNB再发UE Capability Info Indication，给核心网上报UE的无线能力信息。
为了减少空口开销，在IDLE下MME会保存UE Radio Capability信息，在INITIAL CONTEXT SETUP REQUEST消息会带给eNB，除非UE在执行attach或者"first TAU following GERAN/UTRAN Attach" or "UE radio capability update" TAU过程（也就是这些过程MME不会带UE Radio Capability信息给eNB，并会把本地保存的UE Radio Capability信息删除，eNB会问UE要能力信息，并报给MME。注："UE radio capability update" TAU is only supported for changes of GERAN and UTRAN radio capabilities in ECM-IDLE.）。
在CONNECTED下，eNB会一直保存UE Radio Capability信息。
UE的E_UTRAN无线能力信息如果发生改变，需要先detach，再attach。
4) 发起UE上下文释放（即21～25）的条件：
eNodeB-initiated with cause e.g. O&M Intervention, Unspecified Failure, User Inactivity, Repeated RRC signalling Integrity Check Failure, Release due to UE generated signalling connection release, etc.; or MME-initiated with cause e.g. authentication failure, detach, etc.
5) eNB收到msg3以后，DCM给USM配置SRB1，配置完后发送msg4给UE；eNB在发送RRCConnectionReconfiguration前，DCM先给USM配置DRB/SRB2等信息，配置完后发送RRCConnectionReconfiguration给UE，收到RRCConnectionReconfigurationComplete后，控制面再通知用户面资源可用。
6) 消息13~15的说明：eNB发送完消息13，并不需要等收到消息14，就直接发送消息15。
7) 如果发起IMSI attach时，UE的IMSI与另外一个UE的IMSI重复，并且其他UE已经attach，则核心网会释放先前的UE。如果IMSI中的MNC与核心网配置的不一致，则核心网会回复attach reject。
8) 消息9的说明：该消息为MME向eNB发起的初始上下文建立请求，请求eNB建立承载资源，同时带安全上下文，可能带用户无线能力、切换限制列表等参数。UE的安全能力参数是通过attach request消息带给核心网的，核心网再通过该消息送给eNB。UE的网络能力（安全能力）信息改变的话，需要发起TAU。
