Question: In A/Gb mode, when a VLR requests 'MS location information' via the MS Information procedure, what specific information is the VLR requesting from the SGSN?
Option 1: Service Area Identity and Service Area Identity Age
Option 2: Cell Global Identity and Cell Identity Age
Option 3: IMSI and IMEI of the MS
Option 4: Last Known Location of the MS with Time Elapsed
Explanation: A request for 'MS location information' in A/Gb mode translates to a request for Cell Global Identity and Cell Identity Age, crucial for location management, pinpointing the cell where the MS is currently or was last known to be active. Service Area Identity is relevant in Iu mode, not A/Gb. IMSI and IMEI are identity, not location, information. Last Known Location with Time Elapsed might be reported under specific conditions but isn't directly requested by 'MS location information' in A/Gb mode.
