Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nodes exchange comprehensive NPN-related information (support capability, access requirements, resource status), then network self-optimization performance is improved, but communication overhead and system complexity increase
Solution Approach 1:
The NPN-related information is segmented into multiple distinct types: NPN support capability information, NPN access requirement information, and NPN resource status information. Each type is handled and transmitted separately through specific message elements, allowing the system to manage complexity by dividing the overall information exchange task into manageable segments rather than treating it as a single complex operation.
Solution Approach 2:
The information exchange mechanism designed in this patent serves multiple functions simultaneously: it enables network self-optimization decisions, supports handover configurations, provides load balancing capabilities, and facilitates energy saving optimizations. This multi-functional approach reduces the need for separate dedicated mechanisms for each optimization type, thereby managing system complexity while achieving comprehensive network optimization.
2Reliability
If nodes exchange comprehensive NPN-related information (support capability, access requirements, resource status), then network self-optimization performance is improved, but communication overhead increases
Solution Approach 1:
The patent extracts only the essential NPN-related information elements needed for optimization decisions from the complete set of possible node information. Specifically, it extracts NPN support capability, access requirements, and resource status information, excluding unnecessary data. This extraction approach ensures that communication overhead is minimized while still providing sufficient information for effective network self-optimization.
3Productivity
If nodes make informed network self-optimization decisions based on NPN information, then network configuration efficiency is improved, but information processing complexity increases
Solution Approach 1:
Nodes perform preliminary information gathering and organization by collecting NPN support capability, access requirement, and resource status information before actual optimization decisions are made. This preliminary action allows the system to prepare the necessary data structure and content in advance, reducing the processing complexity during the actual decision-making phase and improving overall configuration efficiency.
