Question: What information does the AMF use to determine the AMF PEIPS Assistance Information for a UE?
Option 1: Only local configuration and previous statistical information for the UE.
Option 2: Only the UE's paging probability information and information provided by the RAN.
Option 3: Only the Paging Subgrouping Support Indication and the UE's mobility pattern.
Option 4: Local configuration, the UE's paging probability information if provided, information provided by the RAN, and/or previous statistical information for the UE.
Explanation: The AMF uses a combination of local configuration, the UE's paging probability information if provided, information provided by the RAN (e.g. any of the Information On Recommended Cells And RAN nodes For Paging), and/or previous statistical information for the UE to determine the AMF PEIPS Assistance Information. This allows the AMF to make an informed decision about which paging subgroup to use for the UE.
