Question: What information does the MME provide to the S-GW during Detach and Bearer Deactivation procedures, in addition to the last known location of the UE?
Option 1: The UE's current bearer context
Option 2: Information about the UE's active sessions
Option 3: Details about the UE's subscriber profile
Option 4: Information to enable determination of the time at which the UE was in that location
Explanation: According to the LCS procedures, during Detach and Bearer Deactivation procedures, the MME informs the S-GW of the last known location of the UE and provides additional information to enable the determination of the time at which the UE was in that location. This allows the network to keep track of the UE's location history and timestamp it for potential use in various applications, such as charging and billing.
