Question: Which entity can combine concurrent Mobile Terminating Location Requests (MT-LR) for the same target UE without fully executing all requests, provided privacy requirements are fully resolved?
Option 1: R-GMLC (Gateway Mobile Location Centre), but only if QoS requirements differ between requests
Option 2: H-GMLC (Home Gateway Mobile Location Centre), if no notification or verification is needed for the UE
Option 3: V-GMLC (Visited Gateway Mobile Location Centre), regardless of outstanding privacy actions
Option 4: MSC (Mobile Switching Centre) or SGSN (Serving GPRS Support Node), without considering privacy requirements
Explanation: An H-GMLC is allowed to combine MT-LR requests for the same target UE if privacy requirements can be fully resolved by the H-GMLC, specifically when no notification or verification is needed for the UE. This ensures user privacy is respected while optimizing concurrent location request handling.
