Question: In the context of Lawful Interception (LI) in telecommunications, what is the primary purpose of the Network Element Identifier (NEID) in the Network Identifier (NID) structure?
Option 1: To uniquely identify the subscriber's device (UE: User Equipment) for LI purposes.
Option 2: To uniquely identify the relevant network element carrying out the Lawful Interception operations.
Option 3: To provide a backup identifier in case the Operator/Access/Service Provider identifier is compromised.
Option 4: To specify the type of network (e.g., 5G, LTE, UMTS) for LI handling.
Explanation: The correct answer highlights the NEID's role in identifying the specific network element involved in Lawful Interception activities, crucial for tracing and managing LI operations within a telecom network. The other options are incorrect as they misrepresent the NEID's purpose.
