Question: In a Location Update Notification triggered by UE in a 5G System, what is the expected response from the Application Function (AF) to the Network Exposure Function (NEF) if the AF successfully handles the location estimate of the UE?
Option 1: HTTP Response with '404 Not Found' status code and an error message.
Option 2: HTTP Response with '500 Internal Server Error' status code and a debug log.
Option 3: HTTP Response with no body content, only a '204 No Content' status code.
Option 4: HTTP Response including '200 OK' status code with LocUpdateDataReply data structure.
Explanation: When the AF successfully processes the location update notification from the NEF, it acknowledges this success with a standard HTTP success status code. The '200 OK' status code indicates request success, and the response body contains the expected LocUpdateDataReply data structure, providing feedback on the handled location estimate. This aligns with standard HTTP protocol usage for successful request handling and provides necessary feedback to the NEF in a 5G system's network exposure scenario.
