Question: In a 5G System with wireline convergence access support, how does the Unified Data Management store Forbidden Areas for subscriptions of 5G-CRG and FN-CRG, differing from 3GPP access?
Option 1: Using Tracking Area codes with an additional wireline identifier
Option 2: Employing Global Cell ID for both wireless and wireline accesses uniformly
Option 3: Utilizing a combination of Location Area Code and Cell ID
Option 4: With HFC Node IDs instead of Tracking Area
Explanation: In the context of 5G wireline convergence access, the UDM handles Forbidden Areas for 5G-CRG and FN-CRG subscriptions uniquely by utilizing HFC Node IDs. This approach diverges from traditional use of Tracking Areas in 3GPP wireless access, highlighting an adaptation for wireline environments where HFC infrastructure is prevalent.
