Question: What action does the BBERF (Bearer Binding and Event Reporting Function) take upon unsuccessful enforcement of authorized QoS (Quality of Service) for a service data flow?
Option 1: Automatically modify existing IP CAN (IP Connectivity Access Network) bearer settings to accommodate the requested QoS.
Option 2: Establish a new request for QoS rule provisioning to the PCRF (Policy and Charging Rules Function).
Option 3: Inform the PCRF about the enforcement failure.
Option 4: Immediately free up all reserved resources for the service data flow.
Explanation: Upon unsuccessful QoS rule enforcement, the BBERF's role involves notifying the PCRF to ensure alignment and potential re-evaluation of resource allocation or policy adjustments. This communication is crucial for maintaining network efficiency and adhering to predefined policies, highlighting the importance of feedback loops in telecom networks for effective resource management and QoS assurance.
