Question: When truncation of the 'CAG information list' and corresponding CAG Human-readable network name (HRNN) list is necessary in a User Equipment (UE), what is the priority for inclusion?
Option 1: All CAG IDs from frequent locations are included first, followed by the currently selected PLMN's CAG information.
Option 2: The UE prioritizes and includes first the CAG information of the currently selected Public Land Mobile Network (PLMN), along with its respective HRNN.
Option 3: The truncation is based on alphabetical order of the CAG Human-readable network names, ensuring all names start with a unique character if possible.
Option 4: The UE alternates between including a CAG ID from the 'CAG information list' and then the next from the HRNN list, to maintain balanced truncation.
Explanation: This is correct because, in managing CAG (Closed Access Group) information for USIM Application Toolkit, when space is limited, the UE prioritizes the currently selected PLMN's CAG information and its corresponding HRNN. This ensures seamless and relevant service provision, aligning with telecom scenarios where the immediate, active connection takes precedence.
