Question: What happens when mobile terminated (MT) data or signaling arrives for a UE in RRC_INACTIVE state, and the AMF determines that the UE is not reachable based on the eDRX values provided by NG-RAN?
Option 1: The AMF triggers NG-RAN paging via an N2 RAN Paging Request message.
Option 2: The AMF stores the information received in the NF request and replies to the requesting NF to apply high latency communication functions.
Option 3: The AMF sends a notification to the UE to resume the RRC connection.
Option 4: The AMF discards the MT data or signaling.
Explanation: According to the text, when the AMF determines that the UE is not reachable based on the eDRX values provided by NG-RAN, it stores the information received in the NF request and replies to the requesting NF to apply high latency communication functions as specified in clause 5.31.8. This allows the CN to handle mobile terminated (MT) communication for the UE configured with eDRX for RRC_INACTIVE state.
