Question: In Lawful Interception (LI) for group communication services, what is the primary purpose of assigning a unique correlation number per group communications session to a target?
Option 1: To differentiate between multiple simultaneous voice calls of the same target.
Option 2: To correlate data conveyed over different handover interfaces (e.g., HI2 and HI3) for a specific target within a group communication.
Option 3: To identify the type of service (e.g., voice, data, or video) being intercepted.
Option 4: To indicate the priority level of the Lawful Interception request.
Explanation: The correct answer is Option 2 because, in the context of Lawful Interception for group communications, a unique correlation number per session is crucial for accurately linking and managing the intercepted data that is distributed across various interfaces. This ensures that all relevant data for a specific target within a group communication can be properly correlated and analyzed.
