Question: Which of the following is a primary responsibility of the Evolved Serving Mobile Location Centre (E-SMLC) in the context of User Equipment (UE) positioning in E-UTRAN?
Option 1: Managing the overall network topology and eNode B deployment.
Option 2: Selecting appropriate location methods, invoking them, and determining a single location estimate for target UEs.
Option 3: Providing exclusive support for UE-based position methods without interacting with the network infrastructure.
Option 4: Solely responsible for broadcasting assistance data information to all UEs in the network without segmentation or ciphering.
Explanation: The E-SMLC plays a crucial role in managing different location services, including deciding on the positioning methods (based on various factors like LCS Client type, QoS, UE capabilities, and eNode B capabilities), invoking these methods, and potentially combining results to determine a precise location estimate for target UEs. This process, known as hybrid positioning, highlights the E-SMLC's central role in optimizing location services within the E-UTRAN.
