Solution Overview

Problem

Existing methods for selecting access points in multichannel networks are not optimal, as they do not consider real-time channel quality or user service performance requirements, leading to suboptimal channel performance and impaired user experience.

Innovation Solution

A system and method for dynamically determining an optimal access point based on real-time channel quality metrics and service performance requirements, allowing for automatic selection and mitigation of performance issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual AP selection is used, then user can configure UE to select appropriate AP, but user requires good understanding and prerequisite knowledge on UE and available APs

Engineering Contradiction:

ImproveAP selection processVSAvoiduser knowledge requirement

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system enables automatic AP selection where the UE autonomously evaluates available APs based on real-time channel quality metrics and service performance requirements, eliminating the need for manual user configuration while maintaining optimal selection without requiring user expertise

Inventive Principle:

Principle #25Self-service

2Ease of operation

If automatic AP selection based on static configuration is used, then UE can automatically select AP, but selection is not optimal as it does not consider real-time channel quality or service performance requirements

Engineering Contradiction:

Improveautomatic AP selectionVSAvoidchannel quality stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system transitions from static AP selection criteria to dynamic evaluation by continuously monitoring real-time channel quality metrics and service performance requirements, allowing the UE to adapt its AP selection based on current network conditions and user service needs

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements feedback mechanisms where channel quality metrics and service performance data are continuously collected and used to evaluate AP suitability, enabling optimal AP selection based on actual performance rather than predefined static criteria

Inventive Principle:

Principle #23Feedback

3Ease of manufacture

If AP selection is based on predefined vendor criteria, then implementation is simple, but service performance cannot be guaranteed

Engineering Contradiction:

Improveimplementation simplicityVSAvoidservice performance guarantee

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The system changes the selection parameters from fixed vendor-defined criteria to dynamic parameters including real-time channel quality metrics and service performance requirements, enabling both straightforward implementation through automated evaluation and reliable service performance through data-driven decision making

Inventive Principle:

Principle #35Parameter changes
