Question: What is the primary purpose of including the Mobile Country Code (MCC) in the Visited Country FQDN for N3IWF in a 5G network?
Option 1: To uniquely identify the country where the User Equipment (UE) is located, enabling roaming UEs to determine if the visited country mandates N3IWF selection.
Option 2: To specify the type of services (e.g., emergency, onboarding) supported by the N3IWF in a particular country.
Option 3: To provide additional security through encryption for data transmitted between the UE and the N3IWF.
Option 4: To indicate the preferred language for communication between the UE and network elements in the visited country.
Explanation: The inclusion of the MCC in the Visited Country FQDN for N3IWF is crucial for roaming UEs to identify the country they are currently in. This identification is necessary for determining whether the visited country requires the selection of an N3IWF within its territory, facilitating compliant and seamless connectivity for roaming users.
