Solution Overview

Problem

Portable electronic devices selecting wireless networks based on maximum data rate without considering the actual wireless environment can lead to inconsistent data transmission rates.

Innovation Solution

An electronic device that identifies data transmission control information and determines the best network to access based on channel environment-related indexes such as SINR, network load, and data transmission rates, allowing for adaptive selection of the serving network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the portable electronic device selects the serving network based on maximum data rate supportable by communication networks, then the device can achieve high data transmission capability, but the actual data transmission rate cannot be guaranteed due to ignoring the actual wireless environment

Engineering Contradiction:
Improvedata transmission rateVSAvoiddata transmission rate guarantee
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements feedback by continuously monitoring wireless environment parameters (SINR, network load) and using this information to adjust network selection decisions. The device receives feedback about actual channel conditions and uses this to determine whether to switch networks, ensuring that selection decisions are based on real-time conditions rather than static maximum rate capabilities alone.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies dynamics by making the network selection criteria adaptive rather than fixed. The device dynamically adjusts its network selection based on changing wireless environment conditions, transitioning from a static maximum rate-based selection to a dynamic selection that responds to real-time SINR and network load variations, thereby guaranteeing reliable data transmission rates.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the portable electronic device uses a fixed priority method for network selection, then the selection process is simple and deterministic, but the device does not consider the actual wireless environment such as SINR and network load

Engineering Contradiction:
Improvenetwork selection processVSAvoidwireless environment consideration
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent transforms the static fixed priority method into a dynamic selection process. While maintaining the simplicity of priority-based selection, it adds adaptability by incorporating real-time wireless environment parameters. The device uses priority as a base framework but dynamically adjusts network selection based on measured SINR and network load conditions, achieving both ease of operation and environment adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameters used for network selection from static priority values alone to a combination of priority values and dynamic wireless environment parameters (SINR, network load). By modifying the selection criteria to include these additional parameters, the system maintains operational simplicity while gaining adaptability to actual wireless conditions.

Inventive Principle:
Principle #35Parameter changes
