Question: Under what condition(s) can a UE, subscribed to the call/session-related class in the PS-domain, receive a PS-MT-LR/EPC-MT-LR without notification, if their subscription is for 'location with notification and privacy verification'?
Option 1: If the UE's APN-NI matches the one received from the GMLC, regardless of other settings.
Option 2: If the LCS client identity in the SLPP matches and all GMLC restrictions are met, but only if the UE has an active EPS Bearer-context.
Option 3: Immediately, as long as the UE previously originated a PDP/EPS Bearer-context towards the network where the external client is located.
Option 4: Following notification to the UE, if the UE user either returns a response indicating that location is allowed or returns no response but subscribes to allowing location in the absence of a response.
Explanation: This option correctly outlines the specific scenario for 'location with notification and privacy verification'. For this subscription type, permission for PS-MT-LR/EPC-MT-LR is contingent upon explicit user consent (via response) or implicit consent (through lack of response when the user's settings allow for it). The other options either misinterpret the conditions or apply to different subscription scenarios.
