Question: In a PCC (Policy and Charging Control) context, when a new Flow-Information AVP is included in a QoS-Rule-Definition AVP sent from the PCRF to the BBERF, what happens to any previous Flow-Information AVPs associated with that QoS rule?
Option 1: The new Flow-Information AVP supplements the previous ones, creating a cumulative set of flow information.
Option 2: The new Flow-Information AVP replaces all previous Flow-Information AVPs for that QoS rule.
Option 3: The inclusion of a new Flow-Information AVP triggers a request for confirmation from the BBERF before updating the rule.
Option 4: The new Flow-Information AVP is ignored if there are existing Flow-Information AVPs for the same QoS rule.
Explanation: According to the PCC specifications, when a new Flow-Information AVP is supplied within a QoS-Rule-Definition AVP, it overrides any previous Flow-Information AVPs associated with that specific QoS rule. This ensures that the most recently provided flow information is used for traffic management, reflecting updates or changes in service data flow requirements.
