Question: In a 3GPP network, when supporting interworking with Fixed Broadband Access networks for EPC-routed traffic using GTP-based S5/S8 (case 1), what information shall the PCRF be able to receive from the PCEF for the H(e)NB scenario?
Option 1: UE Local IP Address and TCP Destination Port Number
Option 2: H(e)NB Local IP Address and, if available, UDP Source Port Number
Option 3: BBERF's Global IP Address and Associated TEID
Option 4: ePDG IP Address and WLAN AP MAC Address
Explanation: This is correct because, for supporting interworking with Fixed Broadband Access networks (specifically case 1 involving GTP-based S5/S8 for H(e)NB scenarios), the PCRF must receive the H(e)NB's Local IP Address and, if available, its UDP Source Port Number from the PCEF, crucial for proper traffic handling and policy enforcement in such interworked environments.
