Access Point Network Switching for WLAN Congestion Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless local area networks with a large number of terminal devices, network congestion leads to significant lagging and decreased data transmission rates, as existing technologies fail to effectively manage terminal connections during high loads.
Innovation Solution
A network connection management method that detects congestion events, identifies a target terminal with the lowest priority, and sends a network switching notification to switch the terminal from the local area network to a cellular network when the supported cellular network standard has a higher transmission rate than the current local area network, thereby alleviating congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple terminal devices access the wireless local area network through the router, then the network coverage and connectivity are improved, but serious lagging occurs in data transmission resulting in decreased data transmission rate
Solution Approach 1:
The patent extracts problematic terminals from the congested wireless local area network and relocates them to the cellular network. The router detects network congestion and identifies specific terminals for disconnection, then sends notifications to these terminals to switch to cellular network access, thereby removing the load from the overloaded WLAN while maintaining their connectivity.
Solution Approach 2:
The patent implements dynamic network switching where terminals can transition between wireless local area network and cellular network based on real-time congestion conditions. The system continuously monitors network load and dynamically adjusts terminal connections, allowing terminals to switch networks as needed rather than maintaining static connectivity.
2Ease of operation
If the router allows all terminal devices to connect to the local area network, then network accessibility is improved, but network congestion occurs leading to transmission lagging
Solution Approach 1:
The router actively monitors network congestion levels and extracts terminals that should be disconnected based on priority rules. When congestion is detected, the router identifies target terminals for disconnection and notifies them to switch to cellular network, thereby maintaining accessibility for high-priority terminals while relieving congestion.
Solution Approach 2:
The system changes the network access parameter for specific terminals from WLAN to cellular network based on congestion conditions. By dynamically adjusting which network each terminal uses, the system maintains overall network accessibility while preventing congestion-induced reliability degradation.
3Productivity
If the router disconnects terminals during network congestion, then data transmission rate is improved, but network connectivity is reduced
Solution Approach 1:
The cellular network serves as an intermediary alternative for terminals that need to be disconnected from the congested WLAN. Instead of completely disconnecting terminals, the system mediates by redirecting them to the cellular network, which acts as a backup communication path and maintains their connectivity while relieving WLAN congestion.
Solution Approach 2:
The system implements dynamic connectivity management where terminals can switch between WLAN and cellular network based on real-time conditions. This dynamic approach ensures that terminals maintain connectivity through whichever network is currently less congested, preserving adaptability while improving overall transmission rates.

AI summary
A network connection management method includes: when a preset network congestion event is detected, determining a target terminal, which is to be removed, among terminals which have currently accessed a local area network established by an AP; acquiring information, sent by the target terminal, about a cellular network standard supported by the target terminal; and if the information about the cellular network standard supported by the target terminal satisfies a preset network switching condition, sending a network switching notification to the target terminal, so as to enable the target terminal to be disconnected from the local area network and to access the cellular network. Data transmission rate of the terminal can therefore be improved.
