Question: In a deferred Location Report Procedure, if an SGSN/MSC receives an indication that the UE has moved to another SGSN/MSC while waiting for the requested event, what action does the SGSN/MSC take immediately?
Option 1: Proceed with the location request as described in standard procedures for initial requests
Option 2: Send a Subscriber Location Report to the V-GMLC with instructions to reinitiate MT-LR against the new SGSN/MSC
Option 3: Perform security and privacy check related actions before taking any further steps
Option 4: Record charging information and wait for further instructions from the H-GMLC
Explanation: If the SGSN/MSC detects the UE has moved to another SGSN/MSC while awaiting the requested event, it immediately sends a Subscriber Location Report to the V-GMLC. This report includes instructions for the V-GMLC to reinitiate the Mobile Terminal Location Request (MT-LR) against the new SGSN/MSC, ensuring continuity of the location service despite the UE's movement.
