Question: In a 3GPP-compliant network, when lawful interception is initiated for a User Equipment (UE) already attached to E-UTRAN, what happens if the target UE has multiple active PDN (Packet Data Network) connections?
Option 1: A single event report is generated, aggregating all PDN connections' information.
Option 2: An event report is generated for each active PDN connection of the target UE.
Option 3: No event reports are generated until all PDN connections are deactivated.
Option 4: The interception request is queued until only one PDN connection remains active.
Explanation: In the context of lawful interception in E-UTRAN (Evolved Universal Terrestrial Radio Access Network), if a target UE has multiple simultaneous PDN connections, the system ensures comprehensive monitoring by generating separate event reports for each connection. This approach guarantees that all network activity related to the target UE is reported to the Delivery Function 2 (DF2), if available, thereby maintaining the integrity of the interception process. This is particularly relevant for ensuring detailed surveillance in scenarios where a UE might be utilizing multiple data sessions concurrently.
