Dealing with failures without non 3GPP access to 5gcn

摘要

The interworking function of core network systems such as 5g core network attempts to establish a secure association with user equipment (UE) in an untrusted access network.When a secure association is not acknowledged by the 5g core network, the UE receives a response containing a message type indicating that the non 3G GPP access to the 5g core network is not permitted from the core network.Upon receiving the response message, the UE terminates the session by sending a 5g stop message formatted to the extended authentication protocol (EAP) response.The EAP response / 5G stop message contains a message ID field having a 5g stop value.Diagram
