Question: In Fixed Broadband Access, where does policy control decision-making primarily occur for functionalities like binding and QoS control, according to 3GPP specifications?
Option 1: At the PCRF (Policy and Charging Rules Function) for all scenarios
Option 2: Locally at the PCEF (Policy and Charging Enforcement Function) or at the TDF (Traffic Detection Function)
Option 3: Through a centralized server external to the 3GPP architecture
Option 4: Exclusively on the User Equipment (UE)
Explanation: In Fixed Broadband Access, policy control decision-making for aspects like binding and QoS control is not centralized at the PCRF for all scenarios. Instead, these decisions are made locally, either at the PCEF, which enforces policies, or at the TDF, which detects traffic. This approach allows for more immediate and localized management of network resources without needing to consult a central authority for every decision, enhancing efficiency in fixed broadband contexts.
