【原】看LOG學5G(66)--NSA終端在4G小區的ATTACH

和老康一起學5G 2022-08-03 發布于陜西

展開全文

一、4G(LTE)中Attach

在LTE系統中終端的Attach流程是其在核心網MME上注冊過程；支持NSA的終端(UE)是在回復錨點小區的RRC COnnection Setup Complete消息中包含ATTACH REQUEST((initial-NAS)內容。在消息IE dedicatedInfo NAS中包含了終端初始接入網絡的內容。

圖1.4G終端Attach流程

二、4G中Attach分類

ATTACH REQUEST消息IE中包括EPS Attach類型、EPS移動身份、UE網絡能力、ESM消息容器、終端的舊P-TMSI簽名、GUTI、上次接入注冊TAI、DRX參數、舊位置區域識別、Attach更新類型、語音域偏好和UE使用設置等。其中IE EPS Attach Type指示了附著過程目的，3GPP定義終端附著有三種類型:

EPS attach:僅表示EPS服務的附著;
Combind EPS/IMSI attach:指示EPS和non EPS服務的附著；
EPS Emegency attach：表示緊急承載服務的附著。

其中IE EPS Mobile Identity可以是GUTI、IMSI或IMEI。如果UE持有有效GUTI(本地GUTI或映射GUTI)，則UE應包含GUTI。如沒有效的GUTI可用，UE應包含IMSI作為EPS Mobile Identity IE。如果UE為緊急承載服務而附加，并且如上所述沒有持有有效的GUTI、P-TMSI或IMSI，則IMEI應包含在 EPS移動標識IE中;

ESM消息容器IE是啟用EMM消息中ESM消息的捎帶式傳輸(其可能包含IE，例如EPS承載身份、過程事務身份、PDN連接請求、PDN類型、請求類型、ESM信息傳輸標志、EIT(ESM信息傳輸)、協議配置選項(配置協議、DNS服務器地址請求等)；

IE附加更新類型提供有關組合附加過程請求類型的附加信息。Bit1值0 示“沒有附加信息”，1表示“只有短信”

如果UE支持CS FallBack和SMS over SG，或者如果UE配置為支持IMS語音但不支持1xCS回退，則應包括語音域偏好和UE的使用設置IE。該IE向網絡提供UE的使用設置和E-UTRAN的語音域偏好。詳見3GPPTS24.008第 10.5.5.28 節

如果UE持有有效的最后訪問的注冊跟蹤區域標識(TAI)，則應包括IE最后訪問的注冊TAI。

三、終端Attach Request消息內容

3.1 Attach Request是終端通過eNode向核心網發出的注冊請求。
