Content: Figure 4.15.6.13.4-1: Procedure for revoking a Multi-member AF session with required QoS 1. The AF sends a request to revoke the allocated resources for the traffic flows for the communication between a set of UEs and an AF, using Nnef_AFsessionWithQoS_Revoke request message (Transaction Reference ID). 2. The NEF authorizes the AF request. Steps 3-5 apply for each UE address in the list of UE addresses associated with the Transaction Reference ID: 3. The NEF sends the Npcf_PolicyAuthorization_Delete request as described in clause 5.2.5.3.4 to the PCF. 4. The PCF proceeds with the SM Policy Association Modifications procedure as defined in clause 4.16.5.2. If the NEF has subscribed to notifications (e.g. on resource allocation status, QoS Monitoring of UL and/or DL data rate) for the UE address in the Multi-member AF session, the subscription is also removed. 5. The PCF sends the Npcf_PolicyAuthorization_Delete response message to the NEF. 6. The NEF sends the Nnef_AFsessionWithQoS_Revoke response message (Transaction Reference ID) to the AF.
