Question: In a PMIP-based S5 or S8 architecture, upon detection of an E-UTRAN Attach or UE requested PDN connectivity at the PDN-GW, what is generated by the PDN-GW and sent to the Delivery Function (DF2) with available elements?
Option 1: PMIP Detach/Tunnel Deactivation Event
Option 2: PMIP Attach/Tunnel Activation Event
Option 3: E-UTRAN Location Update Request
Option 4: UE PDN Connectivity Rejection Notice
Explanation: In the context of lawful interception in a PMIP-based S5 or S8 architecture, when an E-UTRAN Attach or a UE's request for PDN connectivity is identified at the PDN-GW, the network initiates procedures to establish the connection while facilitating potential interception. A PMIP Attach/Tunnel Activation Event is generated to notify the Delivery Function (DF2) about the new connection, providing relevant available elements for monitoring or intercept purposes if required, ensuring law enforcement agencies are informed and equipped according to legal mandates.
