Question: In an SGSN, what triggers the transition from the LOCATION state back to the LCS-IDLE state for a specific UE?
Option 1: Receipt of a new location request for another UE
Option 2: Return of a location estimate result from the RAN or expiration of the Location Timer
Option 3: Completion of the Mobility Management connection setup with the UE
Option 4: Successful authentication of the mobile in the LOCATION state
Explanation: The transition from the LOCATION state back to the LCS-IDLE state is triggered by either the receipt of a location estimate result from the RAN (indicating completion of the location process) or the expiration of the Location Timer (suggesting a timeout in the location process), highlighting the importance of timely responses in location services within telecom networks.
