Wireless Access Point Distress Message Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an efficient method for detecting and diagnosing communication failures between a subscriber's gateway and the service provider, requiring subscriber intervention and leading to service disruptions.
Innovation Solution
Implementing a method where a gateway broadcasts probe request distress messages with a specific payload to neighboring access points, which can identify and forward failure reports to the service provider without subscriber intervention, using existing wireless communication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the service provider implements manual diagnostic tests through helpdesk intervention, then connection failure can be diagnosed, but subscriber burden and service disruption time increase
Solution Approach 1:
The gateway performs self-diagnosis by automatically generating and transmitting distress messages when communication failures are detected. The system enables itself to report failures without external intervention, eliminating the need for helpdesk involvement in initial detection and diagnosis.
Solution Approach 2:
The gateway continuously monitors communication link status and provides feedback by sending distress messages when failures occur. This automatic feedback mechanism allows the service provider to receive real-time failure information without manual intervention, reducing both detection time and service disruption.
2Loss of time
If the service provider implements automatic failure detection, then service disruption time is reduced, but system complexity increases
Solution Approach 1:
The gateway uses its existing wireless communication capabilities to serve dual purposes: normal service communication and failure reporting. By leveraging the same wireless interface and protocol stack for both operational communication and distress message transmission, the system avoids adding dedicated hardware while achieving automatic failure detection.
Solution Approach 2:
The distress message acts as an intermediary carrier that conveys failure information from the gateway to the service provider. This standardized message format serves as a universal intermediary that can be transmitted through existing wireless infrastructure without requiring complex dedicated reporting channels or protocols.
3Ease of manufacture
If the gateway transmits distress messages using existing wireless protocols, then no hardware modifications are needed, but message identification and routing complexity increases
Solution Approach 1:
The distress message uses a distinctive payload format and identifier that acts as a 'color code' for message classification. Receivers can quickly identify distress messages through this unique signature in the payload, enabling simple filtering and routing decisions without complex analysis of the message content.
Solution Approach 2:
The wireless communication protocol stack is segmented into distinct functional layers: normal data communication handles service traffic while the distress message mechanism operates as a separate signaling layer. This segmentation allows distress messages to be processed independently through dedicated identification and routing logic, simplifying the overall processing complexity.

AI summary
When a failure is detected of a communication link between a wireless access point and a service provider providing services to devices in proximity of said wireless access point, a probe request message is broadcasted on one or more wireless communication channels. The broadcasted probe request message includes a particular payload enabling the message to be identified as being a distress message reporting a failure of the communication link. Another wireless access point within wireless communication reach receiving a distress message may transfer a communication link failure report to the service provider in place of the wireless access point of which the communication link fails.
