Question: What is the primary purpose of the Correlation Number in the context of Lawful Interception (LI) for MBMS services?
Option 1: To synchronize subscription management events across different networks.
Option 2: To provide a unique identifier for User Equipment (UE) within an MBMS session.
Option 3: To correlate different Intercept Related Information (IRI) records within one MBMS service and session.
Option 4: To trigger asynchronous reporting of subscription management events.
Explanation: The Correlation Number is specifically designed to facilitate the correlation of various IRI records that pertain to a single MBMS (Multimedia Broadcast Multicast Service) service and session. This ensures that related intercept data can be effectively linked and analyzed, which is crucial for lawful interception purposes.
