Question: What is the primary purpose of the SLm interface, as defined between the E-SMLC (Enhanced Serving Mobile Location Centre) and the LMU (Location Measurement Unit), in the context of telecom network architecture?
Option 1: To facilitate communication between the UE (User Equipment) and the E-SMLC for direct positioning requests.
Option 2: To enable the exchange of measurement information for UTDOA (Uplink Time Difference of Arrival) positioning.
Option 3: To manage the deployment and configuration of LMUs within a cellular network.
Option 4: To provide location-based services to emergency response systems.
Explanation: The SLm interface's key function is to facilitate the exchange of measurement data between the E-SMLC and LMU, crucial for UTDOA positioning, a technique determining UE location based on signal time differences at different base stations, vital for various location services.
