Question: During E-UTRA PLMN selection, what additional information must the Access Stratum (AS) report to the Non-Access Stratum (NAS) if the UE supports connection to a 5G Core Network (5GC)?
Option 1: Cell ID of the selected PLMN
Option 2: Signal Strength of available PLMNs
Option 3: Core Network (CN) type associated with the PLMN
Option 4: UE's current location area
Explanation: For efficient network operation, especially when a UE supports advanced connectivity like 5GC, knowing the CN type is crucial for the NAS to manage connections appropriately. This information helps in optimizing the selection process based on the capabilities of both the UE and the network infrastructure, ensuring seamless integration with the 5G Core Network.
