然后如果是盲重定向的话,在NG接口和空口就会分别发送UEContextReleaseRequest和RRC Release给AMF和UE,首先看NGAP的log范例,最能体现发生在重定向场景的是原因值: NGAP { pdu: value NGAP-PDU ::= initiatingMessage : { procedureCode 42, criticality ignore, value UEContextReleaseRequest : { protocolIEs { ...
5G终端(UE)中如存在相关的NG逻辑连接,或AMF在INITIAL UE MESSAGE消息中接收到RAN UE NGAP ID IE,或NG-RAN节点已经启动则AMF启动初始上下文设置流程,或通过另一个NG接口实例发送INITIAL UE MESSAGE消息来建立与UE相关的NG逻辑连接。 对于仅信令连接,如在初始UE消息中未接收到UE上下文请求IE,则AMF可配置为根据运营...
