Question: In the context of lawful interception for inbound roaming users, as per security standards, what triggers the S-GW/BBIFF to notify the Lawful Interception Management System Function (LMISF), regardless of an active intercept?
Option 1: Creation, modification, or deletion of an IMS Signalling Bearer or Media Bearer for S8HR APNs
Option 2: Receipt of a SIP URL or TEL URL target identity
Option 3: Activation or deactivation of CC interception for a voice call
Option 4: Change in the UE's location, as reported by the MME
Explanation: According to the specified security architecture, the S-GW/BBIFF notifies the LMISF upon changes (creation, modification, or deletion) to specific bearers (IMS Signalling Bearer or Media Bearer for S8HR APNs), ensuring the LMISF has updated information for effective lawful intercept management.
