Question: In Lawful Interception (LI) scenarios, as per 3GPP security standards, what happens when a call to an intercepted target's Directory Number (DN) is forwarded, regardless of the forwarding party?
Option 1: The call is not intercepted since it was forwarded, and only direct calls are monitored.
Option 2: Only the calling party's information is sent to the Law Enforcement Agency (LEA), without any diversion details.
Option 3: The call is intercepted with CC (Call Content) links established, and relevant diversion-related information, including IRI (Interception Related Information) records, is sent to the LEA.
Option 4: Interception occurs but only for specific types of call forwarding, not all kinds.
Explanation: This option correctly reflects the behavior described in the context of Lawful Interception (LI) for diverted calls. When a call to an intercepted target's DN is forwarded, the system ensures that the call content (CC links) is still intercepted, and any available information related to the diversion (including IRI records) is sent to the Law Enforcement Agency (LEA). This comprehensive approach ensures that all relevant details are captured for investigative purposes, regardless of whether the forwarding was initiated by the calling or called party.
