Question: In a Fixed Broadband Access scenario, what is a key aspect of the QoS Enforcement function performed by the Policy and Charging Enforcement Function (PCEF)?
Option 1: Enforcing UE-initiated bearer procedures for IP-CAN bearers
Option 2: Converting QoS parameters from PCRF to specific Fixed Broadband Access QoS attributes
Option 3: Mandating Application Detection functionality across all network operations
Option 4: Supporting NW-initiated bearer procedures for enhanced QoS control
Explanation: In the context of Fixed Broadband Access, the PCEF's role in QoS enforcement involves translating or converting QoS parameters received from the Policy and Charging Rules Function (PCRF) into specific QoS attributes understandable by the Fixed Broadband Access network. This conversion is crucial for ensuring that the intended Quality of Service is properly enforced at the access level, highlighting the importance of interoperability between policy control and broadband access technologies.
