Question: In an MMTel charging context, what is a key characteristic of how communication-related information (e.g., Terminating Identity, Originator Identity) is handled for the Malicious Communication Identification (MCID) service?
Option 1: The information is stored under the control of both the originating and terminating entities.
Option 2: The information is kept under Network Operator's control, inaccessible to both the terminating and originating entities.
Option 3: The data is temporarily shared with the served user for verification purposes before being discarded.
Option 4: Such information is not stored at all to maintain user privacy.
Explanation: The MCID service's design ensures that sensitive communication-related information is securely managed. A crucial aspect of this management is that the Network Operator retains control over this data, ensuring it remains inaccessible to both the terminating and originating entities. This approach safeguards user privacy and security while facilitating the effective identification of malicious communications.
