Wireless Communication Device AP Failure Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless LAN network systems face issues where a failure in a network connection at an access point (AP) can lead to 'black hole' scenarios, where devices cannot access the Internet, and existing solutions like mesh access point portals can cause communication rate declines due to increased load on adjacent APs.
Innovation Solution
A wireless communication device with detection, determination, and relay functions that assess network connection failures and make independent wireless connections to APs, allowing for separate communication relaying and reducing the risk of 'black hole' scenarios and communication rate declines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an AP stops all wireless networks when a wired network connection failure occurs, then the black hole problem is resolved, but slave devices may not be able to connect to adjacent APs when the number of wirelessly belonging slave devices is restricted
Solution Approach 1:
The patent segments the wireless network connection function by introducing a dedicated first wireless connection unit specifically for connecting to failed APs, separate from the second wireless connection unit used for slave devices. This segmentation allows independent operation of connection functions, enabling the system to maintain connectivity to failed APs while managing slave device connections without interference.
Solution Approach 2:
The patent introduces an intermediary mechanism where the first wireless connection unit acts as a mediator between the controller and failed APs. The controller determines whether to connect to failed APs based on radio wave status, and the first wireless connection unit executes these decisions independently, serving as an intermediary that resolves the contradiction between reliability and adaptability.
2Reliability
If another AP becomes a mesh access point portal to connect to a failed AP, then slave devices can access the Internet, but communication rates of slave devices may decline due to increased load on the adjacent AP
Solution Approach 1:
The patent segments the wireless connection functions into two independent units: the first wireless connection unit for connecting to failed APs and the second wireless connection unit for connecting to slave devices. This segmentation allows the system to maintain communication with failed APs through the controller without forcing slave devices to route through adjacent APs, thereby preserving communication rates while ensuring Internet access capability.
Solution Approach 2:
The patent extracts the connection function to failed APs from the normal wireless operation by using a dedicated first wireless connection unit that operates independently from the second wireless connection unit handling slave devices. This extraction removes the burden of increased load on adjacent APs while maintaining the ability to access failed APs through the controller.
3Stability of the object's composition
If the number of wirelessly belonging slave devices of an AP is restricted, then connection stability is improved, but some slave devices may not be able to belong to the AP
Solution Approach 1:
The patent implements multi-functionality by enabling the controller to manage multiple types of connections simultaneously: connections to failed APs through the first wireless connection unit and connections to slave devices through the second wireless connection unit. This universal approach allows the system to accommodate both connection stability requirements and slave device accommodation needs without restriction.

AI summary
In order to enable reducing a possibility of being unable to connect to an AP in which a failure of a network connection occurs and also lessening a decline in a communication rate, a wireless communication method includes: detecting occurrence of a failure of a network connection in a first wireless communication device, when detecting the occurrence of the failure, determining whether or not to make a first wireless connection to the first wireless communication device, when making the determination to make the first wireless connection, making the first wireless connection to the first wireless communication device, and relaying a first communication between the first wireless communication device and a network.
