Wireless Device Distress Message for Connectivity Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in diagnosing and resolving wireless connectivity issues when adding a new wireless device to a network, leading to lower user satisfaction and increased complexity for both users and call center personnel, due to the complexity of setting up correct wireless connectivity parameters.
Innovation Solution
A method where the impaired wireless device sends a 'distress message' with error information embedded in a communication protocol, which is analyzed by a diagnostic tool to determine the cause of the problem and suggest solutions, using a unique key for secure communication and embedding information in Probe Request Management Frames for diagnosis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive query language capabilities and predefined rules are used for automatic diagnosis, then diagnostic coverage is improved, but the system complexity and difficulty of implementation increase
Solution Approach 1:
The impaired wireless device autonomously generates and transmits a distress message containing diagnostic information without requiring external diagnostic tools or complex query language processing. The device self-services by embedding its configuration parameters and error information directly in the transmitted message, eliminating the need for sophisticated external analysis systems.
Solution Approach 2:
The essential diagnostic information (configuration parameters, error information, device identifiers) is extracted from the complex system state and isolated into a dedicated distress message structure. This separates the critical diagnostic data from the overall system complexity, making it accessible and analyzable without requiring comprehensive query capabilities.
2Adaptability or versatility
If users manually configure wireless connectivity parameters, then configuration flexibility is improved, but the ease of operation and troubleshooting difficulty worsen
Solution Approach 1:
The system implements automatic feedback by having the impaired device transmit its configuration parameters and error information to a diagnostic tool. The diagnostic tool analyzes this feedback information and generates troubleshooting recommendations, creating a closed-loop system that automatically responds to configuration errors without requiring manual user analysis.
Solution Approach 2:
A diagnostic tool acts as an intermediary between the user-configured device and the troubleshooting process. The diagnostic tool receives the distress message, analyzes the configuration parameters and error information, and provides interpreted guidance to users, bridging the gap between complex technical parameters and user-friendly troubleshooting.
3Ease of operation
If call center personnel handle wireless setup problems, then user support is improved, but the time required for resolution and operational efficiency worsen
Solution Approach 1:
The system performs preliminary diagnostic action automatically by having the impaired device pre-packaging its configuration parameters and error information in a distress message before contacting support. This preliminary action provides call center personnel with ready-analyzed information, eliminating the need for them to gather diagnostic data during the support interaction and reducing overall resolution time.
4Ease of operation
If wireless network configuration is made simple, then ease of setup is improved, but the ability to diagnose configuration errors worsens
Solution Approach 1:
The patent replaces manual error detection mechanisms with an automated electronic diagnostic system. Instead of requiring users to manually check configuration parameters or wait for call center analysis, the impaired device automatically extracts and transmits its configuration data and error state through the distress message, enabling electronic automated diagnosis that maintains setup simplicity while improving error detection.
