Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If 5G networks increase throughput and coverage using higher frequencies like millimeter wave, then network capacity and bandwidth are improved, but network complexity and management difficulty increase
Solution Approach 1:
The patent segments network management by introducing cell-level and RAN-level composite load indicators that divide the overall network into manageable units. Each cell can be independently monitored and managed based on its specific load conditions, making the complex high-frequency network easier to control through standardized metrics.
Solution Approach 2:
The patent introduces KPI indicators as intermediary elements between network resources and management systems. These indicators (cell composite load, RAN condition) serve as mediators that translate complex network states into actionable information, enabling simplified monitoring and decision-making for high-frequency network operations.
2Adaptability or versatility
If 5G networks deploy new radio access technologies to enrich connectivity, then service capability is improved, but system complexity and operational difficulty increase
Solution Approach 1:
The patent creates universal KPI indicators that can be applied across multiple radio access technologies and network configurations. The cell composite load and RAN condition indicators serve as multi-functional metrics that work regardless of specific RAT implementations, simplifying operational complexity while maintaining versatility.
Solution Approach 2:
The patent standardizes network monitoring through defined parameter changes in KPI formulations. By establishing standardized parameter sets for load indicators and RAN conditions, the system can adapt to different radio access technologies using consistent measurement frameworks, reducing operational complexity despite technological diversity.
3Reliability
If navigation applications use real-time KPI data to dynamically adjust routes, then user experience and reliability are improved, but data processing requirements and system complexity increase
Solution Approach 1:
The patent enables preliminary route planning by providing navigation applications with advance KPI data about cell conditions and RAN status. Applications can pre-evaluate potential routes using historical and real-time indicator data, selecting optimal paths before execution, which reduces real-time processing complexity while improving reliability.
Solution Approach 2:
The patent establishes feedback loops where KPI indicators continuously inform navigation decisions. Real-time cell composite load and RAN condition data feed back to navigation applications, enabling dynamic route adjustments based on actual network conditions without requiring complex real-time processing, as the feedback mechanism uses standardized, pre-processed indicators.
