Question: When a target UE is marked as 'detached' in the VLR, MSC Server, or SGSN, and an LCS client has requested its location, what information does the network entity include in its response if notification to the target UE doesn't apply?
Option 1: Current Location with an uncertainty indicator
Option 2: Last Known Location without a timestamp
Option 3: Last Known Location together with a timestamp
Option 4: No Location Information due to detached state
Explanation: When a UE is 'detached', its current location may not be available. If an LCS client requests the UE's location and doesn't require notification to the target UE, the network responds with the Last Known Location to provide some level of location awareness. Including a timestamp is crucial for indicating how stale the location information might be, aiding the LCS client in assessing its relevance.
