Solution Overview

Problem

Current wireless networks often fail to meet the needs of mobile devices, leading to poor network quality and lag in service operations, such as gaming and video playback, which negatively impacts user experience.

Innovation Solution

A channel switching method that monitors network quality and switches data flows to an alternate network channel when preset conditions are not met, ensuring that all sensitive flows are transferred to a better quality channel, thereby maintaining service quality and improving user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If only the first data flow is switched to the second network channel when network quality deteriorates, then the lag caused by poor network quality of the first data flow is resolved, but the lag caused by poor network quality of the second data flow remains unresolved

Engineering Contradiction:
Improvenetwork qualityVSAvoidchannel switching complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the switching decisions for multiple data flows by monitoring their network qualities collectively. When any data flow (first or second) experiences poor network quality, the system switches both flows to the alternate network channel together, rather than handling them independently. This merging approach ensures that both flows benefit from the same quality assessment and switching decision, resolving the contradiction between individual flow reliability and overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If all data flows are switched to the second network channel when one flow's network quality deteriorates, then all sensitive flows are protected from lag, but network channel utilization becomes less efficient

Engineering Contradiction:
Improveservice qualityVSAvoidnetwork resource utilization
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies local quality assessment to each data flow individually, evaluating their network qualities separately before making switching decisions. However, the switching action is applied collectively to all sensitive flows. This allows the system to maintain high service quality for all flows by protecting them all when one flow experiences deterioration, while the individual quality assessment ensures that switching is triggered only when necessary, balancing reliability with resource utilization efficiency.

Inventive Principle:
Principle #3Local quality

AI summary

Disclosed are a channel switching method, an electronic device, and a storage medium. The electronic device includes a first network channel and a second network channel. The method includes: starting a first application, where the first application includes a first data flow and a second data flow, and the first data flow and the second data flow are carried on the first network channel; and switching the network channel carrying the first data flow and the second data flow to the second network channel in a case of detecting that network quality of the first data flow does not meet a preset condition. This application can better resolve the lag in service operation, thereby improving user experience.
