Question: What should the SEAF/AMF do when a primary authentication or NAS SMC procedure is ongoing on a parallel NAS connection?
Option 1: Initiate a new primary authentication or NAS SMC procedure.
Option 2: Wait for the completion of the ongoing primary authentication or NAS SMC procedure before initiating a new one.
Option 3: Terminate the ongoing primary authentication or NAS SMC procedure and initiate a new one.
Option 4: Ignore the ongoing primary authentication or NAS SMC procedure and continue with normal operations.
Explanation: According to the rules related to parallel NAS connections, the SEAF/AMF shall not initiate a primary authentication or NAS SMC procedure in case a primary authentication or a NAS SMC procedure is ongoing on a parallel NAS connection. This is to avoid mismatches between the security contexts in the network and the UE.
