Monitoring Event Deletion Initiated from HSS

When a subscriber is deleted from the HSS while monitoring is active or the authorization for monitoring is revoked, the HSS sends an RIR command to the SCEF with the Event-Handling AVP set to the value CANCEL.

SCEF finds and deletes the context for Monitoring Event Subscription corresponding to SCEF Reference ID received in RIR message from HSS.
