Lawful Interception Resource Cleanup via Auditing Ownership Transfer

The system performs preliminary actions by establishing auditing records and ownership relationships before the SMF failure occurs. When a SMF fails, the ownership mechanism is already in place to immediately trigger resource cleanup, eliminating the need for timeout-based waiting. The auditing record is created upfront with the SMF's NEID as the claimant, so when failure occurs, the transition of ownership and subsequent cleanup can happen immediately without delay.

The system implements a feedback mechanism where the auditing record continuously tracks the ownership status of LI resources. When an SMF fails, the system receives feedback about the failure and automatically triggers the ownership transfer and resource cleanup process. This closed-loop feedback ensures that resources are cleaned up promptly in response to actual failure conditions, maintaining data interception legality while requiring minimal manual intervention.

The auditing mechanism enables self-service by allowing the system to automatically manage resource cleanup without external intervention. When an SMF fails, the auditing record's ownership is automatically transferred to another SMF in the set, which then autonomously performs the resource cleanup. This self-service capability achieves timely resource cleanup while the complexity is confined to the automated ownership management logic rather than requiring complex external control systems.

The auditing record serves as an intermediary that mediates between SMF failures and resource cleanup actions. Instead of requiring direct manual intervention to clean up resources after SMF failure, the auditing record automatically tracks ownership and triggers the appropriate cleanup actions. This intermediary mechanism maintains data interception legality through automated ownership management while reducing the need for complex manual operations, balancing reliability and ease of operation.
