Question: In a scenario where E-UTRA is connected to both Evolved Packet Core (EPC) and 5th Generation Core Network (5GC), how does the User Equipment (UE) handle access control information for each core network type?
Option 1: The UE combines access control information from both EPC and 5GC to make a unified decision.
Option 2: The UE uses the access control information associated with the core network type selected by the Non-Access Stratum (NAS).
Option 3: The UE always prioritizes access control information from 5GC over EPC for all connections.
Option 4: The UE ignores access control information from EPC when connected to 5GC.
Explanation: This is correct because, as per the described functionality, when E-UTRA is connected to both EPC and 5GC, it broadcasts separate access control information for each. The UE then selectively uses the access control information based on the core network type (EPC or 5GC) chosen by the NAS, ensuring compatibility and appropriate handling of access controls depending on the selected core network architecture.
