Question: What is the primary composition of IRI (Intercept Related Information) messages transmitted over the Handover Interface for Lawful Interception (HI2)?
Option 1: A single, unified block containing all intercept and general information.
Option 2: A header for general information (e.g., LIID, timestamp) and a payload for intercept-related details.
Option 3: An encrypted segment for security and a clear-text segment for ease of processing.
Option 4: A dynamic structure that changes based on the type of intercepted data.
Explanation: The correct answer reflects the structured approach to IRI messages as defined by telecom standards for efficient and secure data handling. This composition facilitates organized transmission: the header provides contextual (general) information, while the payload contains specific intercept-related data, crucial for streamlined processing in Lawful Interception scenarios within telecommunications networks.
