Question: In a Fixed Broadband Access scenario, what additional information may the Policy and Charging Enforcement Function (PCEF) report to the Policy and Charging Rules Function (PCRF) for Home eNodeB (H(e)NB) connections?
Option 1: Only the H(e)NB's globally unique identifier
Option 2: The UE/H(e)NB Local IP address and the UDP port number, if available
Option 3: The type of attached User Equipment (UE) and its battery life
Option 4: The H(e)NB's throughput capacity and signal strength
Explanation: In Fixed Broadband Access scenarios involving Home eNodeB (H(e)NB), the PCEF can provide more detailed connectivity information to enhance policy and charging control. Reporting the UE/H(e)NB Local IP address and UDP port number, if available, allows for finer-grained management of network resources and policy enforcement based on specific device connections and application usage.
