Terminate Policy Association Call Flow Description

Step

Description

1

When PCF terminates the policy association, it initiates a terminate notification by sending the Npcf_ AMPolicyControl_UpdateNotify request to AMF.

2

The AMF responds to PCF with the confirmation indicating that Npcf_AMPolicyControl_Delete is initiated. Depending on the termination notification, AMF removes the policy association and initiates delete request.

3

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

4

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 sending notifications to the original AMF.
