Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile networks face challenges in providing sufficient coverage and capacity, especially in urban environments where signal attenuation from infrastructure is significant, and handover issues arise due to noise or changes in link performance, necessitating improved techniques for selecting and maintaining optimal backhaul nodes.
Innovation Solution
A node configured with scanning circuitry to detect upstream nodes, connection circuitry to form and manage connections, and processing circuitry to perform scanning based on triggers, allowing for controlled selection and reselection of backhaul nodes based on performance characteristics and operator-defined criteria, thereby optimizing network throughput and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If handover is disabled to prevent node reselection during use, then network stability is improved, but the ability to adapt to changing network conditions deteriorates
Solution Approach 1:
The patent implements dynamic handover mechanisms that allow the system to transition between stable operation and adaptive reselection based on network conditions. The node can maintain a stable connection under normal conditions while automatically initiating scanning and reselection procedures when performance thresholds are breached, achieving both stability and adaptability through conditional dynamic behavior.
2Measurement precision
If scanning is performed frequently to detect upstream nodes, then the ability to select optimal backhaul nodes is improved, but network throughput deteriorates due to connection breaks
Solution Approach 1:
The patent implements periodic scanning triggered by performance thresholds rather than continuous scanning. The system monitors link performance continuously and initiates scanning only when predefined thresholds are breached, creating a periodic action pattern that balances measurement precision with throughput maintenance by limiting scanning to necessary moments.
Solution Approach 2:
The system performs self-assessment of link performance and autonomously decides when scanning is necessary based on monitored metrics. This self-service mechanism eliminates the need for external control signals, allowing the node to independently determine optimal scanning moments based on its own performance state, thereby balancing selection accuracy with throughput preservation.
3Duration of action of stationary object
If connection to upstream node is maintained continuously, then network coverage is improved, but the system becomes vulnerable to signal attenuation and interference from urban infrastructure
Solution Approach 1:
The patent implements preliminary scanning and candidate identification before connection failures occur. By proactively identifying alternative upstream nodes and monitoring link performance, the system prepares backup connections in advance, allowing seamless switching when attenuation or interference degrades the current connection, thus maintaining coverage continuity while improving reliability.
