Question: In a Local Breakout (LBO) architecture with P-CSCF in the Visited Public Land Mobile Network (VPLMN) for VoLTE, which network element is responsible for providing Content of Communication (CC) interception?
Option 1: P-CSCF in the VPLMN
Option 2: PDN-GW/GGSN or IMS-AGW deployed in the VPLMN
Option 3: HSS (Home Subscriber Server) in the Home Public Land Mobile Network (HPLMN)
Option 4: MME (Mobility Management Entity) in the VPLMN
Explanation: In the context of Local Breakout with P-CSCF in the VPLMN for VoLTE, the PDN-GW/GGSN or the IMS-AGW deployed in the VPLMN is tasked with providing Content of Communication (CC) interception. This is because these elements are involved in the data path and can thus intercept the content as required by lawful interception protocols. The P-CSCF triggers CC intercept to these elements but does not perform CC interception itself in this scenario. HSS and MME are not directly involved in the interception of communication content in this context.
