When PCF must change the policy, it initiates an update notification by sending the Npcf_ AMPolicyControl_UpdateNotify request to AMF.

2

The AMF responds to PCF with the confirmation indicating that update policy is enforced.

In case the update policy enforcement was unsuccessful, the AMF redirects the subsequent notification to the new AMF.

In case of 404 error, AMF responds to PCF stating that it must search for a new URI using the IPv4 or IPv6 address, or refrain from sends notifications to the original AMF.
