Question: In a 3GPP network, what is the primary purpose of the Enhanced Location for IRI (Interception Related Information) in Lawful Access Location Services (LALS)?
Option 1: To determine a target's location during emergency calls only.
Option 2: To determine the LCS-based location of a target when specific user service events related to the target occur.
Option 3: To provide periodic location updates for all subscribers on the network.
Option 4: To override subscriber location privacy settings for commercial Location Services (LCS) requests.
Explanation: Enhanced Location for IRI is specifically designed to capture the LCS-based location of a target in response to particular service events related to that target, distinguishing it from general positioning or periodic updates. This aligns with the need for targeted and event-driven location interception in lawful access scenarios.
