看LOG学5G(66)-NSA终端在4G小区的ATTACH

看LOG学5G(66)--NSA终端在4G小区的ATTACH\o"5G"#5G\o"NSA"#NSA一、4G(LTE)中Attach在LTE系统中终端的Attach流程是其在核心网MME上注册过程；支持NSA的终端(UE)是在回复锚点小区的RRCCOnnectionSetupComplete消息中包含ATTACHREQUEST((initial-NAS)内容。在消息IEdedicatedInfoNAS中包含了终端初始接入网络的内容。图1.4G终端Attach流程二、4G中Attach分类ATTACHREQUEST消息IE中包括EPSAttach类型、EPS移动身份、UE网络能力、ESM消息容器、终端的旧P-TMSI签名、GUTI、上次接入注册TAI、DRX参数、旧位置区域识别、Attach更新类型、语音域偏好和UE使用设置等。其中IEEPSAttachType指示了附着过程目的，3GPP定义终端附着有三种类型:EPSattach:仅表示EPS服务的附着;CombindEPS/IMSI

attach:指示EPS和nonEPS服务的附着；EPSEmegency

attach：表示紧急承载服务的附着。其中IEEPSMobileIdentity可以是GUTI、IMSI或IMEI。如果UE持有有效GUTI(本地GUTI或映射GUTI)，则UE应包含GUTI。如没有效的GUTI可用，UE应包含IMSI作为EPSMobileIdentityIE。如果UE为紧急承载服务而附加，并且如上所述没有持有有效的GUTI、P-TMSI或IMSI，则IMEI应包含在EPS移动标识IE中;ESM消息容器IE是启用EMM消息中ESM消息的捎带式传输(其可能包含IE，例如EPS承载身份、过程事务身份、PDN连接请求、PDN类型、请求类型、ESM信息传输标志、EIT(ESM信息传输)、协议配置选项(配置协议、DNS服务器地址请求等)；IE附加更新类型提供有关组合附加过程请求类型的附加信息。Bit1值0示“没有附加信息”，1表示“只有短信”如果UE支持CSFallBack和SMSoverSG，或者如果UE配置为支持IMS语音但不支持1xCS回退，则应包括语音域偏好和UE的使用设置IE。该IE向网络提供UE的使用设置和E-UTRAN的语音域偏好。详见3GPPTS24.008第8节如果UE持有有效的最后访问的注册跟踪区域标识(TAI)，则应包括IE最后访问的注册TAI。三、终端AttachRequest消息内容3.1

AttachRequest是终端通过eNode向核心网发出的注册请求。
