Question: What is the primary role of the NG-C interface in UE-positioning-related procedures between the gNB/ng-eNB and the AMF?
Option 1: To process and analyze positioning requests and results
Option 2: To transparently transport NR positioning protocol(s) as a transport link
Option 3: To manage ciphering keys for unicast positioning data
Option 4: To handle NAS message routing unrelated to positioning
Explanation: The NG-C interface acts as a pass-through, ensuring transparency in UE-positioning procedures by merely transporting positioning requests and results between the LMF and gNB/ng-eNB without altering or processing them. This facilitates efficient communication without introducing additional latency or complexity to the positioning process.
