Question: In an LCS (Location Services) scenario, when an H-GMLC (Home Gateway Mobile Location Centre) sends an LCS Identity Request, what attribute(s) does the PMD include in its response to the H-GMLC?
Option 1: Cell ID and Location Area Code
Option 2: Target UE identity (one or both of MSISDN: Mobile Subscriber Integrated Services Digital Network Number and IMSI: International Mobile Subscriber Identity)
Option 3: Serving System Identifier and Tracking Area Code
Option 4: Temporary Mobile Subscriber Identity and Packet Temporary Mobile Subscriber Identity
Explanation: In the context of Location Services, when an H-GMLC requests identity information for location purposes, the responding network element (PMD) would logically provide identifiers directly associated with the target device/user. MSISDN and IMSI are fundamental identifiers for a UE in cellular networks, linking to the subscriber's phone number and global unique identifier, respectively. These are crucial for accurately pinpointing and managing location services for the correct user/device.
