Question: What action does the Location Subscriber Authorization Function (LSAF) take when it detects that the identity used to address a target UE is a pseudonym?
Option 1: Blocks the location service (LCS) request for security reasons
Option 2: Automatically subscribes the UE to the requested LCS service
Option 3: Directly provides the location information without further verification
Option 4: Calls the Location Subscriber Translation Function to translate the pseudonym to a verinym
Explanation: The correct answer is Option 4 because, according to the described functionality of LSAF in the context of telecom networks, when a pseudonym is detected, the logical next step for authorization and verification purposes would be to translate this pseudonym into a verinym (a verified or true identity) through the Location Subscriber Translation Function. This ensures that the location service can be accurately authorized for the actual subscriber, maintaining security and integrity in the provision of LCS.
