Channel Switching Method for Network Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks often fail to meet service requirements, leading to service stalls due to deteriorating mobile phone signals, and channel switching between primary and secondary networks can result in high delays and further service stalls, negatively impacting user experience.
Innovation Solution
A channel switching method that detects scenario changes and switches from a primary network channel to a secondary network channel by identifying a characteristic packet flow, collecting statistics, and determining the path of the secondary network channel based on service type and quality metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If channel switching is performed when service stall is detected, then service continuity is improved, but switching delay increases causing service to be stalled
Solution Approach 1:
The patent detects and stores the path of the second network channel in advance based on scenario changes (such as location changes detected by GPS or base station information) before service stall actually occurs. This preliminary detection and storage of alternative channel paths eliminates the time delay that would otherwise be spent searching for available channels when switching is needed, thus resolving the contradiction between ensuring service continuity and minimizing switching delay.
2Reliability
If acceleration channel is enabled to meet service requirement, then service quality is improved, but switching delay increases and service may be stalled
Solution Approach 1:
The system performs preliminary detection of the second network channel path based on scenario changes before actual channel switching is required. By storing the detected path information in advance, the system avoids the time-consuming process of channel search and switching when service quality degradation is detected, thus improving both service quality and switching efficiency simultaneously.
Solution Approach 2:
The patent replaces the traditional mechanical channel switching process (which involves scanning and selecting channels) with a pre-determined path switching mechanism. Instead of physically searching for available channels when switching is needed, the system uses scenario-based detection to identify and store alternative paths in advance, substituting the mechanical search process with a more efficient information-based approach.
