Question: In a 5G System (5GS) where a 5G-Radio Access Gateway (5G-RG) connects to the 5G Core Network (5GC) via wireline access, what key adaptation is made to the session management principles defined for User Equipment (UE)?
Option 1: The 5G-RG uses a different protocol stack than UE for session management.
Option 2: The session management principles remain unchanged regardless of the device or access type.
Option 3: The wireline RAT type replaces the need for a specific Radio Access Technology (RAT) in session setup.
Option 4: The 5G-RG is treated as a UE, with no adaptations needed for wireline access in session management.
Explanation: In adapting session management principles for a 5G-RG connected via wireline access, the key difference lies in how the 5G-RG (acting similarly to a UE but over a different access type) interacts with the 5GC. This necessitates an adaptation in protocol handling or interaction, akin to using a different protocol stack tailored for wireline access, as opposed to the wireless access designed for UEs. Thus, Option 1 correctly identifies that the 5G-RG would use a different protocol stack than UE for session management over wireline access.
