National Surveillance Database for Communication Network Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks lack a national surveillance database to effectively monitor and correlate identities of individuals under surveillance, especially with the rise of anonymous communication technologies and multiple identities per subscriber, posing challenges for law enforcement to respond swiftly to security threats.
Innovation Solution
A system and method that utilize a national surveillance database to provide communication-related information to communication nodes, which screen signaling messages and perform surveillance actions by correlating subscriber identities through an ENUM database, ensuring real-time monitoring and response capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a national surveillance database is implemented to monitor communication resources, then surveillance effectiveness and law enforcement capability are improved, but system complexity and infrastructure requirements increase
Solution Approach 1:
The patent introduces a surveillance database as an intermediary component that mediates between communication network elements and law enforcement agencies. This database serves as a centralized repository that stores surveillance information and provides it to network elements like switching equipment and telecommunication processors, enabling effective surveillance without requiring direct complex integration between all system components.
Solution Approach 2:
The surveillance system is segmented into distinct functional components: a centralized surveillance database, communication network elements (switches, routers), and law enforcement interfaces. Each component has specific responsibilities - the database stores and manages surveillance information while network elements handle communication routing and filtering, reducing overall system complexity through functional decomposition.
2Measurement precision
If multiple communication identities per subscriber are correlated, then surveillance accuracy is improved, but data processing complexity and information management difficulty increase
Solution Approach 1:
The patent creates copies of subscriber identification information across multiple database tables and network elements. Instead of maintaining a single source of truth, the system replicates identification data (such as directory numbers, SIP URIs, and other communication identifiers) across different storage locations and processing nodes, enabling comprehensive correlation of multiple identities while distributing the processing burden.
Solution Approach 2:
The surveillance database is designed with universal data structures that can accommodate multiple types of subscriber identifiers and communication modalities. The same database infrastructure handles correlation of traditional telephone numbers, IP telephony identifiers, mobile device IDs, and other communication identities, eliminating the need for separate specialized systems for each identity type.
3Speed
If real-time monitoring of communication attempts is provided, then response speed to security threats is improved, but network overhead and processing resource consumption increase
Solution Approach 1:
The patent implements partial monitoring by having network elements selectively query the surveillance database only when necessary - specifically when call detail records indicate potential surveillance targets. Rather than continuously processing all communication data, the system performs targeted queries and actions only for relevant calls, reducing overall processing resource consumption while maintaining real-time response capability for monitored individuals.
Solution Approach 2:
The surveillance database is pre-configured with lists of monitored individuals and communication identifiers before actual surveillance operations begin. Network elements use these pre-loaded surveillance lists to quickly identify and flag relevant communication attempts without performing complex real-time analysis of all traffic, enabling fast response while minimizing processing overhead through advance preparation.

AI summary
Methods, systems, and computer program products are disclosed for providing surveillance monitoring in a communication network based on a national surveillance database. Communication-related information is received from a national surveillance database that includes communication-related information relating to individuals under surveillance. The received communication-related information is used to screen signaling messages relating to communications associated with the individuals.
