Question: Which of the following is NOT a primary function of the Evolved Serving Mobile Location Centre (E-SMLC) in relation to UE location services in an E-UTRAN network?
Option 1: Calculating the final location and velocity estimate for a UE.
Option 2: Interacting with the UE for UE-assisted and UE-based position methods.
Option 3: Managing overall coordination and scheduling of resources for UE location.
Option 4: Handling end-to-end encryption for all communication between UEs and external networks.
Explanation: The E-SMLC's primary functions, as outlined, include managing resource coordination for UE location, calculating final location estimates, interacting with UEs for certain position methods, and providing assistance data. While the E-SMLC may forward ciphering keys to subscribed UEs via the MME for specific purposes (like broadcast assistance data), handling end-to-end encryption for all communication between UEs and external networks is not identified as a primary function of the E-SMLC within the provided context, which focuses on location services.
