Question: When an Application Function (AF) indicates to a Policy and Charging Rules Function (PCRF) that a media flow should no longer share Allocation and Retention Priority with other flows, how should the PCRF handle the remaining services that were previously sharing priority?
Option 1: Immediately terminate all remaining shared priority services.
Option 2: Readjust the Allocation and Retention Priority for the remaining services as per PCC/QoS rule provisioning procedures and handle the excluded flow according to normal rules.
Option 3: Ignore the change and continue with the existing priority sharing configuration for all remaining services.
Option 4: Request additional information from the AF before making any changes to priority allocations.
Explanation: When a media flow is excluded from priority sharing, the PCRF needs to rebalance the priorities of the remaining flows that were part of the shared priority group. This involves adjusting the Allocation and Retention Priority (ARP) values for these services according to defined PCC/QoS rule provisioning procedures, ensuring efficient resource management and maintaining service quality for the remaining shared priority services. The excluded flow is then managed under standard PCC/QoS rules, separate from the shared priority mechanism.
