Question: What action does the User Equipment (UE) take when it receives a PDU SESSION AUTHENTICATION RESULT message during a UE-requested PDU session release procedure, and the indicated PDU session is the one being released?
Option 1: The UE sends a 5GSM STATUS message with the 5GSM cause IE set to #43 "Invalid PDU session identity".
Option 2: The UE pauses the UE-requested PDU session release procedure until the authentication result is processed.
Option 3: The UE terminates the PDU SESSION AUTHENTICATION RESULT message transport procedure.
Option 4: The UE ignores the PDU SESSION AUTHENTICATION RESULT message and proceeds with the UE-requested PDU session release procedure.
Explanation: When a collision occurs between the UE-requested PDU session release procedure and the reception of a PDU EAP result message transport procedure, the UE should prioritize the ongoing release procedure to maintain consistency in its state. By ignoring the authentication result message and continuing with the release procedure, the UE ensures that it correctly transitions out of the releasing PDU session state.
