Question: In a scenario with multiple BBERFs (e.g., flow mobility case), how does a PCEF specify the target BBERF for event triggers when subscribing to an Event Report Indication, if not explicitly specified?
Option 1: By omitting the Event-Trigger AVPs in the CCR command.
Option 2: By including the Routing-IP-Address AVP within the Event-Report-Indication AVP.
Option 3: Through separate CCR commands for each BBERF, without any specific AVP indication.
Option 4: It is not possible to specify a target BBERF in such scenarios.
Explanation: When multiple BBERFs are present (as in flow mobility cases), the PCEF needs a way to identify which BBERF the event triggers are intended for. Including the Routing-IP-Address AVP within the Event-Report-Indication AVP serves this purpose, allowing the PCEF to target specific BBERFs with the event triggers. If this AVP is not included, the event triggers will be applied to all BBERFs by default. This highlights the importance of precise configuration in complex network scenarios to ensure intended functionality.
