Question: In a 3GPP-compliant network, when all bearers belonging to the same PDN connection are released simultaneously, how are bearer deactivation events handled by the S-GW/PDN-GW in relation to delivery to the DF2 for Lawful Interception?
Option 1: A single aggregated event is sent for all bearers to the DF2.
Option 2: No event is sent to the DF2 since all bearers are released at once.
Option 3: One event is sent for each bearer to the DF2, even if all are released simultaneously.
Option 4: The S-GW/PDN-GW decides dynamically based on network load, sending either a single or multiple events.
Explanation: This is correct because, according to the specified behavior for bearer deactivation in the context of Lawful Interception, when all bearers of the same PDN connection are released at the same time, the system generates and sends one event for each bearer. This ensures that interception capabilities can accurately track changes at a granular (per-bearer) level, even in scenarios involving simultaneous releases.
