Question: What information, as per 3GPP standards for Lawful Interception, MUST be transferred from a PDG/WAG to DF3 to facilitate its functionality, EXCLUDING the intercepted content of communications itself?
Option 1: Target Identity, Correlation Number, Time Stamp
Option 2: Direction (MO/MT), Target Location, Authentication Credentials
Option 3: Time Stamp, Direction (MO/MT) only
Option 4: Target Identity, Correlation Number, Time Stamp, Direction (MO/MT), and Target Location (if available)
Explanation: For DF3 to perform its lawful interception functionality effectively, it requires comprehensive metadata. This includes the **Target Identity** for pinpointing the subject, **Correlation Number** for linking related intercepts, **Time Stamp** for chronological context (even if optional, it's part of the required set when present), **Direction (MO/MT)** to understand the communication flow (again, optional but crucial when provided), and **Target Location** (if available) for spatial awareness. This combination ensures DF3 can process intercepts with full contextual understanding, making Option 4 the correct answer.
