Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensing network and communication network operate independently with separate duties, then each network can maintain its own functionality, but the integration and unified management of the two networks is insufficient
Solution Approach 1:
The patent merges the sensing network and communication network into a unified network architecture where both networks share common infrastructure and management mechanisms. The base station simultaneously handles both communication services and sensing functions, while the core network device provides unified access control and restriction management for both network types through integrated signaling protocols.
2Reliability
If terminal devices are allowed to access all sensing networks without restrictions, then network accessibility is maximized, but security and service quality control deteriorate
Solution Approach 1:
The system performs preliminary actions by pre-configuring restriction information in the core network device before terminal devices attempt to access sensing networks. The core network device stores access restrictions, terminal device identifiers, and sensing network type associations in advance, enabling automated access control decisions without requiring complex real-time evaluations during the access process.
Solution Approach 2:
The core network device acts as an intermediary between terminal devices and sensing networks, mediating access control by evaluating restriction information against terminal identifiers and network types. This intermediary mechanism automates the access control process, providing reliable security checks while maintaining ease of operation through transparent automated decision-making.
3Measurement precision
If detailed restriction information is implemented for different sensing network types, then access control precision is improved, but information processing complexity increases
Solution Approach 1:
The patent segments restriction information by sensing network types, creating distinct restriction records for different sensing network categories (e.g., video sensing, sensor networking). Each restriction information element is structured with specific fields for terminal device identifiers, sensing network type identifiers, and access control parameters, enabling precise control while maintaining organized, manageable data structures.
