Question: In a Location Services (LCS) operation, what is the primary responsibility of the LCS functional entities in the Core Network after receiving a location request from the LCS server?
Option 1: Determine the position of the target UE using positioning protocols.
Option 2: Verify authorization, support, and privacy allowances before forwarding the request to the Access Network.
Option 3: Establish a direct connection with the UE to gather location information.
Option 4: Send accounting information to an accounting function without waiting for location results.
Explanation: The correct answer, Option 2, reflects the sequence of operations as described. After the LCS server passes the request to the Core Network’s LCS functional entities, their primary responsibilities include verifying the requesting client’s authorization, ensuring the UE supports LCS, checking for privacy or other restrictions on locating the UE, and then determining which Access Network element should receive the location request. This step ensures that the request is legitimate and feasible before proceeding with the location determination, which is actually performed by the Access Network LCS functional entities (as indicated in Option 1, but that’s not the question’s focus regarding Core Network responsibilities).
