Question: In a Policy and Charging Control (PCC) architecture, under what condition does the provisioning of CSG (Closed Subscriber Group) information reporting indication to the Traffic Detection Function (TDF) apply?
Option 1: When the PCRF (Policy and Charging Rules Function) is integrated with the SPR (Subscription Profile Repository)
Option 2: Throughout the lifetime of any IP-CAN (IP Connectivity Access Network) session
Option 3: Only during initial IP-CAN/TDF session establishment
Option 4: When the ABC (Access Bearer Control) feature is supported
Explanation: The provisioning of CSG information reporting indication to the TDF applies specifically when the ABC (Access Bearer Control) feature is supported, highlighting the importance of feature support in determining the applicability of certain functionalities within telecom networks, particularly in policy and charging rules enforcement related to subscriber group management.
