Question: In a Location Services (LCS) scenario, what is the primary purpose of sending an LCS Privacy Profile Update notification from the PPR to the H-GMLC?
Option 1: To request location information for a specific UE (User Equipment)
Option 2: To update the H-GMLC about changes in the network's overall security policy
Option 3: To notify the H-GMLC of changes to a Target UE's privacy profile, identified by MSISDN and/or IMSI
Option 4: To initiate a new location service for a group of UEs
Explanation: The LCS Privacy Profile Update notification informs the H-GMLC about alterations made to the privacy settings of a particular UE, identified by MSISDN or IMSI (or both), ensuring location services respect the updated user privacy preferences.
