Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user terminals autonomously select networks and distribute data based on local policies, then user autonomy and network selection flexibility are improved, but network performance optimization and operator control deteriorate
Solution Approach 1:
The patent introduces an operator server as an intermediary between user terminals and multiple networks. The server collects terminal capabilities, network status information, and policy requirements, then autonomously generates optimized data distribution policies. This mediator resolves the contradiction by maintaining user autonomy in network selection while centralizing performance optimization and control functions in the operator server.
Solution Approach 2:
The system implements continuous feedback loops where the operator server collects real-time network status information and terminal behavior data, analyzes performance metrics, and dynamically adjusts data distribution policies accordingly. This feedback mechanism ensures network performance optimization while preserving user autonomy, as policies are continuously refined based on actual network conditions and user needs.
2Reliability
If data distribution policies are centralized and dynamically adjusted by operator server, then network performance and operator control are improved, but system complexity and information processing requirements deteriorate
Solution Approach 1:
The patent segments the centralized control system into distinct functional modules: information collection module, policy generation module, and policy execution module. The operator server collects specific types of information (terminal capabilities, network status), processes them separately to generate policies, and distributes them to appropriate terminals. This segmentation reduces system complexity by organizing functions into manageable, independent components.
Solution Approach 2:
The operator server is designed as a universal platform that handles multiple functions: collecting information from diverse terminals and networks, analyzing various performance metrics, generating different types of data distribution policies, and managing multiple networks simultaneously. This multi-functionality consolidates complexity into a single versatile system rather than requiring separate specialized systems for each function.
3Adaptability or versatility
If user terminals collect and process extensive network information autonomously, then network selection intelligence is improved, but terminal device complexity and energy consumption deteriorate
Solution Approach 1:
The patent extracts the complex information processing and policy generation functions from user terminals and relocates them to the operator server. Terminals only need to collect basic network status information and transmit it to the server, which then performs the intensive analysis and generates optimization policies. This extraction dramatically reduces terminal energy consumption while maintaining intelligent network selection capabilities through server-side processing.
Solution Approach 2:
Instead of having terminals autonomously process extensive network information and make intelligent decisions, the system inverts the approach: terminals collect minimal information and receive intelligent policy decisions from the operator server. This inversion transfers the computational burden from energy-constrained terminals to the power充足的 operator server, reducing terminal energy consumption while preserving adaptability.
4Productivity
If multiple networks are available for user terminal access, then network capacity and service diversity are improved, but network selection complexity and data distribution management deteriorate
Solution Approach 1:
The operator server acts as an intermediary management system between user terminals and multiple available networks. It collects information about various networks (cellular, WLAN, WiMAX, etc.), analyzes their status and capabilities, and generates optimized data distribution policies that automatically route traffic across appropriate networks. This mediator simplifies network selection and data distribution management while enabling utilization of multiple networks for enhanced capacity and service diversity.
Solution Approach 2:
The system dynamically changes distribution policy parameters based on network conditions, terminal capabilities, and service requirements. The operator server adjusts data distribution strategies by modifying parameters such as routing preferences, bandwidth allocation, and network selection criteria in response to changing network status information. This parameter-based control enables flexible management of multiple networks without increasing system complexity.
