Question: In EPS to 5GS handover using the N26 interface, what parameter(s) from the target 5GS TAI are used for selecting an Access and Mobility Management Function (AMF)?
Option 1: Only the 5GS Tracking Area Code (TAC)
Option 2: Mobile Country Code (MCC) alone
Option 3: Mobile Network Code (MNC) exclusively
Option 4: Combination of 5GS TAC, MNC, and MCC
Explanation: The target 5GS TAI's comprehensive parameters - including the 5GS Tracking Area Code (TAC), Mobile Network Code (MNC), and Mobile Country Code (MCC) - are collectively used for selecting an appropriate AMF during EPS to 5GS handover via the N26 interface, ensuring accurate AMF identification based on geographical and network-specific identifiers.
