Solution Overview
Problem
Mobile terminals connected to wide area communication networks, such as the Internet, face challenges in being protected from security attacks and managing incident occurrences due to their free usage in various locations.
Innovation Solution
A communication control device that acquires identification information from authenticated communication terminals and connects them to specific units in a narrow area network based on pre-defined connection information, ensuring secure and managed communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If terminals are freely connected to the wide area communication network for use in any place, then the ease of operation is improved, but the security protection and incident management capability deteriorate
Solution Approach 1:
The patent introduces a communication control device as an intermediary between terminals and the wide area communication network. This device authenticates terminals and controls their connection status, enabling security management while maintaining terminal mobility and usability across different locations.
2Ease of operation
If terminals are freely connected to the wide area communication network for use in any place, then the ease of operation is improved, but the incident management capability deteriorates
Solution Approach 1:
The communication control device implements feedback mechanisms by monitoring terminal connection status, authentication states, and communication activities. This enables the system to detect and manage incidents related to terminal usage on the wide area network while preserving user convenience.
3Reliability
If terminals are authenticated and connected to specific connection units in a narrow area network, then the security protection is improved, but the device complexity increases
Solution Approach 1:
The communication control device performs multiple functions including authentication, connection management, and security control within a single system. This multi-functionality approach strengthens security protection while avoiding the need for multiple separate complex systems.
