Solution Overview
Problem
As communication systems become more sophisticated and communication networks more complex, existing systems struggle to easily identify signals related to attacks on the communication networks.
Innovation Solution
A communication system configured to receive threat information from outside organizations and execute protection processes to safeguard communication devices within the network, utilizing components like the Network Exposure Function (NEF) and Policy Control Function (PCF) in a 5G core network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication systems become more sophisticated with complex networks, then communication capabilities are improved, but the ability to identify attack signals is worsened
Solution Approach 1:
The patent introduces an external organization as an intermediary that specializes in threat information collection and analysis. This external entity acts as a mediator between the complex communication network and the security protection mechanism, providing processed threat intelligence that the internal system can use without having to develop complex detection capabilities itself. The control device receives and processes this intermediary-provided threat information to implement protection measures.
2Adaptability or versatility
If the communication network structure becomes more complex, then network functionality is improved, but security management simplicity is worsened
Solution Approach 1:
The patent extracts the complex task of threat intelligence collection and analysis from the internal communication system and places it in an external organization. This separation allows the communication network to maintain its sophisticated functionality while outsourcing the security management complexity to a specialized external entity, thereby simplifying internal security operations.
3Adaptability or versatility
If threat information formats from external organizations vary, then information sources are improved, but processing compatibility is worsened
Solution Approach 1:
The patent implements parameter changes by transforming threat information from various external formats into a standardized internal format. The control device performs format conversion and parameter normalization on received threat information, changing its structural parameters to be compatible with the communication system's processing requirements. This allows the system to accept diverse information sources while maintaining processing consistency.
