Question: In a 3GPP network utilizing PMIP-based S5/S8, when lawful interception is initiated for a target with an active PMIP tunnel, what action does the PDN-GW take regarding event record generation if multiple connections are active?
Option 1: The PDN-GW generates a single consolidated event record for all active connections.
Option 2: The PDN-GW ignores generating event records until only one connection is active.
Option 3: The PDN-GW defers sending event records to the DF2 until tunnel deactivation.
Option 4: For each active connection, the PDN-GW generates a separate event record and sends defined parameters to the DF2 if available.
Explanation: This is correct because when lawful interception starts for a target with an active PMIP tunnel and multiple connections are active, the PDN-GW is required to generate an event record for each connection. These records include parameters related to PMIP attach/tunnel activation, which are sent to the Delivery Function 2 (DF2) if available, ensuring comprehensive monitoring of all active connections for the target under interception.
