Question: In 3GPP-compliant networks, when a Packet Data Header Report event is triggered for lawful interception, which of the following best describes the reporting frequency and scope?
Option 1: Summarized reporting on a periodic basis, covering multiple packets transmitted by the target.
Option 2: Non-summarized reporting on a per packet basis, triggered by each packet sent or received by the target.
Option 3: Reporting only for packets exceeding a certain size threshold, to optimize network resource utilization.
Option 4: Scheduled reporting at fixed intervals, regardless of packet transmission activity.
Explanation: The correct answer, Option 2, aligns with the specification that the Packet Data Header Report event provides 'non-summarized reporting on a per packet basis' and is triggered by each packet sent or received by the target. This ensures detailed, real-time monitoring for lawful interception purposes, highlighting the importance of granular data in security and surveillance contexts within telecom networks.
