Solution Overview

Problem

In wireless networks, devices often connect to access points with higher signal strength but lower data traffic rates, leading to suboptimal data services.

Innovation Solution

An electronic device scans access points with the same SSID, calculates data traffic rates based on beacon frames, and selects the access point with the highest data traffic rate for connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electronic device connects to the access point with higher signal strength, then the connection stability is improved, but the data traffic rate deteriorates

Engineering Contradiction:
Improveconnection stabilityVSAvoiddata traffic rate
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent changes the selection parameter from signal strength alone to a composite criterion that includes both signal strength and data traffic rate. The processor calculates the data traffic rate based on beacon frame information and uses this additional parameter to make the AP selection, thereby resolving the contradiction between connection stability and data traffic rate.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the electronic device selects access point based on signal strength only, then the selection process is simple, but the data service quality deteriorates

Engineering Contradiction:
Improveselection process simplicityVSAvoiddata service quality
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system automatically calculates the data traffic rate using beacon frame information and performs the optimized AP selection without user intervention. The processor extracts relevant parameters from beacon frames, computes the data traffic rate, and autonomously selects the optimal AP, maintaining ease of operation while improving data service quality.

Inventive Principle:
Principle #25Self-service

3Productivity

If the electronic device calculates data traffic rate for each access point, then the data service quality is improved, but the processing complexity increases

Engineering Contradiction:
Improvedata service qualityVSAvoidprocessing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent performs preliminary extraction of necessary information from beacon frames before the actual AP selection process. By pre-calculating the data traffic rate using already-available beacon frame parameters (such as basic rate and extended rate information), the system avoids complex real-time calculations during the selection moment, thus reducing processing complexity while maintaining data service quality.

Inventive Principle:
Principle #10Preliminary action
