Question: For a 5G-RG (5G-Wireless and Wireline Convergence Access) connecting over wireline access, how are service area restrictions identified for FN-CRG (Fixed Network - Cable Related Group) subscriptions?
Option 1: Based on the UE's (User Equipment) IP Address
Option 2: Using an HFC Node ID, or by a list of HFC_Node IDs
Option 3: Depending on the 5G-RG's MAC (Media Access Control) Address
Option 4: Through frequent location updates from the UE to the network
Explanation: For FN-CRG subscriptions, service area restrictions are effectively managed by identifying the specific location of the FN-CRG using an HFC Node ID, which uniquely identifies a node on the cable network, or by referencing a list of such IDs for broader area definitions. This approach ensures precise control over service access based on the physical location of the FN-CRG.
