Question: What triggers a Packet Data Summary Report for a unique packet flow associated with an EPS bearer in a Lawful Interception scenario?
Option 1: Expiration of a configurable Summary Timer per intercept, reaching a per-intercept configurable count threshold, start/end of a packet flow, or interim report for a packet flow.
Option 2: Only when the target's data session (EPS bearer) is terminated.
Option 3: Upon detection of the first IPv6 packet in a flow, requiring Flow Label reporting.
Option 4: When the total transmitted/received bytes exceed a predefined limit for an EPS bearer.
Explanation: A Packet Data Summary Report is triggered by multiple events to ensure timely and relevant information delivery for Lawful Interception. These include the expiration of a configurable Summary Timer, reaching a threshold count of packets/bytes, the start of a new packet flow, the end of a packet flow or EPS bearer, and interim reports for ongoing flows. This comprehensive approach supports effective monitoring and analysis.
