Enforcement at AMF for Emergency PDU

During the triggering process of enforcement for a RAT or a core restriction type, the AMF performs the following actions:

  • The AMF starts the deregistration process toward the PCF or the UDM, when the UE has an emergency PDU established before.

  • The AMF initiates the release only for non-emergency PDU, whereas the emergency PDU remains active.

  • The AMF moves the UE as an option of emergency registered.
