Question: In E-UTRAN, what is the primary purpose of the Location Information Transfer Procedure between the E-SMLC (Evolved Serving Mobile Location Centre) and the UE (User Equipment)?
Option 1: To facilitate handover decisions based on UE velocity.
Option 2: To enable the E-SMLC to request UE's power settings for interference reduction.
Option 3: To allow UEs to query nearby cell tower locations for better coverage.
Option 4: To enable the E-SMLC to request position measurements from, or receive location measurements for position calculation from, the UE.
Explanation: This is correct because the Location Information Transfer Procedure is specifically designed for exchanging location-related data. The E-SMLC uses this procedure to either obtain position measurements directly from the UE (for network-assisted location) or to receive measurements from the UE for calculating its location (as in basic self-location scenarios where the UE initiates its own location request). This aligns with the practical application of location services in telecom networks, such as emergency services, tracking, and location-based services.
