Wireless Access Point Connection Restoration via Device Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for restoring wireless data network connections after a primary connection failure are inadequate, especially in networks with unpredictable access points controlled by individual users, as they require pre-programmed data on alternative access points, which is impractical due to the dynamic nature of these networks and potential overload on neighboring access points.
Innovation Solution
A process where the access point detects a loss of connection and instructs connected data processing devices to scan for and connect to alternative wireless access points, allowing them to identify and establish the best connection based on signal quality and contention, without pre-programmed redirection routes, and automatically re-establish network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If pre-programmed redirection instructions are stored in the access point, then automatic connection restoration is enabled, but the system becomes impractical for dynamic networks with user-controlled access points
Solution Approach 1:
The data processing device autonomously performs the connection restoration process by scanning for beacon signals from alternative access points and establishing connections without requiring pre-programmed instructions or manual intervention. The device independently identifies suitable alternative access points and executes reconnection, making the system adaptable to dynamic networks while maintaining automation.
Solution Approach 2:
Instead of having the access point direct terminals to specific alternative access points (top-down approach), the invention inverts the approach by enabling terminals to autonomously discover and select alternative access points themselves (bottom-up approach). This reversal makes the system flexible enough to handle dynamic networks while preserving automatic restoration capability.
2Reliability
If traffic is diverted to a single alternative access point, then connection restoration is achieved, but service quality deteriorates due to overload on the alternative access point
Solution Approach 1:
The invention segments the traffic flow by enabling multiple data processing devices to connect to different alternative access points based on their respective signal conditions and locations. Instead of concentrating all diverted traffic on a single alternative access point, the segmentation distributes the load across multiple access points, preventing overload and maintaining service quality while achieving reliable connection restoration.
3Ease of operation
If troubleshooting information is downloaded in advance, then access to troubleshooting resources is enabled, but user foresight and storage capacity are required
Solution Approach 1:
The invention enables preliminary action by allowing data processing devices to autonomously scan for and connect to alternative access points with troubleshooting resources when the primary connection fails. Instead of requiring users to pre-download troubleshooting information, the system performs the necessary actions in advance by automatically directing devices to access points that host troubleshooting resources, making resources accessible without user foresight or pre-installation.

AI summary
In the event of loss of connection (4) between an access point (3) and a data network (5), the access point (3) transmits instructions to a data processing device (1) connected to the access point (3) to cause the data processing device (1) to re-establish connection to the data network (5) by another means. These instructions cause the data processing device to scan for beacon signals from further wireless access points, and establish connection (7, 8) to the data network (5) through a wireless access point (6) identified in the scanning process.
