Question: In a Trusted Non-3GPP Access scenario, when a UE is assigned both IPv6 Home Network Prefix (HNP) and IPv4 Home Address (HoA), what procedure must the Mobility Access Gateway (MAG) follow?
Option 1: PMIPv6 PDN Connection IPv6 Address Allocation Procedure
Option 2: LMA Initiated IPv4 Address Release Procedure
Option 3: UE Initiated IPv6 Prefix Delegation Procedure
Option 4: MAG Initiated IPv4 Address Refresh Procedure
Explanation: When a User Equipment (UE) is assigned both an IPv6 Home Network Prefix (HNP) and an IPv4 Home Address (HoA) in a Trusted Non-3GPP Access scenario, the network must efficiently manage these dual assignments. The correct procedure to follow in this case is the LMA Initiated IPv4 Address Release Procedure, ensuring proper management of the IPv4 address allocation when both IPv6 and IPv4 addresses are assigned to the UE, preventing potential conflicts or inefficiencies in address utilization.
