Question: In Lawful Interception (LI) for connection-oriented communications, what is the primary purpose of assigning a unique Communication Identity Number (CIN)?
Option 1: To differentiate between various network elements within the same operator's infrastructure.
Option 2: To uniquely identify an intercepted communication session within a relevant network element, ensuring all related interception results share this identifier.
Option 3: To distinguish between circuit-switched and packet-switched communications for a single target identity.
Option 4: To enable the merging of interception data from different operators for collaborative investigations.
Explanation: The CIN's role is to uniquely identify an intercepted communication session within a specific network element, ensuring all results from intercepting this single session are correlated through the shared CIN, facilitating organized lawful interception practices.
