Question: Under what conditions can a CS-MT-LR (Cell Station Mobile Terminal-Location Request) be allowed for a UE (User Equipment) that subscribes to the call/session-related class in the CS-domain, when the UE user has subscribed to 'location with notification and privacy verification'?
Option 1: If the called party number matches and the LCS client identity is verified, without requiring any response from the UE.
Option 2: Only if the UE user returns a response indicating that location is allowed, after being notified.
Option 3: Automatically, at the start of the call, as long as the UE's SLPP (Secure Location Platform Protection) allows it.
Option 4: If the UE user either returns a response allowing location or returns no response but has a subscription allowing location in the absence of a response.
Explanation: This option correctly outlines the specific conditions under which a CS-MT-LR can be allowed for a UE with 'location with notification and privacy verification' subscription. It requires either an explicit allowance from the user after notification or, if the user has previously agreed to allow location in cases of no response, then implicitly by their pre-set preference. This ensures user privacy is respected while still enabling location services under agreed-upon conditions.
