Question: In a convergent scenario with both fixed broadband access network and Evolved Packet Core (EPC), what is the role of PCRF in controlling the fixed broadband access network?
Option 1: The PCRF controls the fixed broadband access network directly without mediation, for both Non-seamless WLAN offload traffic from 3GPP UE and fixed devices.
Option 2: The PCRF relies on a BPCF (Broadband Policy Control Function) for mediating policy decisions to the fixed broadband access network.
Option 3: The PCRF is bypassed in favor of a dedicated policy server designed specifically for fixed broadband access networks in convergent scenarios.
Option 4: The control is distributed between PCRF for mobile traffic and a separate entity for fixed broadband access, with no direct PCRF control over the latter.
Explanation: In a convergent setup, the Policy and Charging Rules Function (PCRF) directly controls network elements within the fixed broadband access. This applies to traffic from both Non-seamless WLAN offloaded from 3GPP User Equipment (UE) and fixed broadband devices, streamlining policy and charging management without an intermediary policy server.
