Solution Overview
Problem
In areas with multiple base stations, terminal stations face challenges in receiving radio signals due to varying propagation characteristics and heavy interference, leading to frequent wireless communication disconnections and congestion as they autonomously select connection destinations.
Innovation Solution
A wireless communication system with a control station that collects and processes information from base stations about signal strengths and terminal stations to manage connection permissions, ensuring stable communication by controlling the connection destinations of terminal stations among multiple base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If terminal stations autonomously select connection destinations based on signal strength, then connection flexibility is improved, but communication stability deteriorates due to frequent switching and congestion
Solution Approach 1:
The patent introduces a base station as an intermediary that mediates connection decisions between terminal stations and the network. Instead of terminal stations autonomously selecting connections, the base station receives connection requests, evaluates signal strengths from multiple base stations, and makes the connection decision. This intermediary role resolves the contradiction by centralizing control to improve stability while maintaining adaptability through signal-based evaluation.
Solution Approach 2:
The patent implements a feedback mechanism where terminal stations report received signal strengths from multiple base stations to the serving base station. The base station uses this feedback information to make informed connection decisions, adjusting connections based on current wireless conditions. This feedback loop enables stable connections by continuously adapting to changing signal conditions without requiring autonomous terminal station decisions.
2Measurement precision
If terminal stations switch connections frequently in response to signal variations, then connection quality is improved, but communication disconnection increases
Solution Approach 1:
The patent applies preliminary action by having terminal stations measure and report signal strengths from multiple base stations before making connection decisions. The base station evaluates these preliminary measurements and determines the optimal connection target in advance, rather than switching connections reactively when signal quality degrades. This prevents frequent switching and associated disconnections while maintaining connection quality through proactive optimization.
3Ease of operation
If multiple terminal stations connect to the same base station, then connection simplicity is improved, but network congestion worsens
Solution Approach 1:
The base station acts as an intermediary that manages connection distribution to prevent congestion. When multiple terminal stations request connections, the base station evaluates signal strengths and systematically assigns terminals to appropriate base stations, balancing the load across the network. This maintains connection simplicity for terminals while preventing congestion through centralized management.
Solution Approach 2:
The patent changes the connection parameter from simple signal-strength-based selection to a managed assignment system where the base station considers both signal strength and current load conditions. By dynamically adjusting connection assignments based on network state parameters, the system prevents congestion while maintaining ease of operation for terminal stations.
