Mobile Device Probe Responses for Reliable Access Point Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices often connect to access points that do not provide internet access or are blocked by firewalls, requiring users to manually reconfigure connections, causing inconvenience.
Innovation Solution
A mobile device and access point system that sends probe requests and responses to confirm connectivity before establishing a connection, using MPDU format to include connection requirements and targets, and records connection results for automatic switching to available access points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the mobile device automatically connects to the access point that the user has previously manually connected to, then the connection speed is improved, but the reliability of internet access deteriorates
Solution Approach 1:
The access point performs preliminary action by testing connectivity to the internet target (such as pinging a website or resolving a domain name) before establishing the wireless connection with the mobile device. The connection test result is included in the probe response frame, allowing the mobile device to verify internet accessibility before actually connecting, thus preventing connection to inaccessible access points while maintaining automatic connection behavior.
2Reliability
If the mobile device manually reconfigures the Wi-Fi connection when internet access is unavailable, then the reliability of internet access is improved, but the ease of operation deteriorates
Solution Approach 1:
The system implements self-service by having the access point automatically perform connectivity testing and include the test result in the probe response frame. The mobile device automatically uses this information to determine whether to establish the connection, eliminating the need for users to manually check internet availability or reconfigure connections when accessibility issues occur.
3Ease of operation
If the mobile device connects to the access point without confirming connectivity, then the ease of operation is improved, but the reliability of internet access deteriorates
Solution Approach 1:
The access point provides feedback by including the connectivity test result directly in the probe response frame sent to the mobile device. This feedback mechanism allows the mobile device to automatically adjust its connection decision based on the actual internet accessibility status of the access point, maintaining ease of operation while improving reliability through automatic connectivity verification.
