Wireless LAN Failure Diagnosis via Video-Operational Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless LAN systems face challenges in identifying and narrowing down failure factors for connection failures, particularly due to obstacles affecting communication between wireless terminals and access points, without sufficient information on usage situations, leading to prolonged troubleshooting.
Innovation Solution
A network operation management system that integrates imaging units to capture video images and manage operational information in association with captured dates, allowing for the display of video images and operational data to facilitate the identification of failure factors by administrators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional wireless LAN systems monitor operational status without video imaging, then system complexity is reduced, but the ability to identify failure factors deteriorates
Solution Approach 1:
The patent combines video imaging functionality with wireless LAN operational monitoring by integrating a video acquisition unit that captures images correlated with operational status data. This merging allows administrators to visually verify physical conditions (obstacles, terminal positions) while simultaneously reviewing operational parameters, thereby improving failure factor identification accuracy without requiring separate monitoring systems.
2Loss of time
If video imaging is integrated with operational monitoring, then failure factor identification improves, but loss of time in troubleshooting worsens
Solution Approach 1:
The system continuously acquires and stores video images correlated with operational status data before failures occur. When a failure is detected, administrators can immediately retrieve pre-captured images and operational data without waiting for separate investigations, thereby reducing troubleshooting time. The video acquisition unit operates in advance to ensure relevant visual information is already available when needed.
Solution Approach 2:
The patent adds a visual dimension to operational monitoring by incorporating video imaging capabilities. This transforms the monitoring system from purely data-based to a multi-dimensional system that combines operational parameters with visual evidence, enabling more comprehensive failure analysis without requiring multiple separate systems.
3Ease of operation
If operational information is managed without visual correlation, then information management simplicity is maintained, but ease of operation in diagnosing failures deteriorates
Solution Approach 1:
The patent merges operational information management with visual documentation by correlating operational status data with captured video images. This integration preserves complete usage situation information including both quantitative operational metrics and qualitative visual context, making failure diagnosis easier without losing any relevant information.
Solution Approach 2:
The video images serve as an intermediary that bridges operational data and physical reality. By storing and displaying images correlated with operational status, the system provides visual context that helps administrators understand the physical environment during failures, thereby improving diagnostic ease without losing usage situation information.

AI summary
A network operation management system includes: an imaging unit configured to capture a video image in a predetermined sight of the area; a wireless management unit configured to obtain operational information of the wireless terminal, and to manage the obtained operational information in association with an obtained date; and a video image management unit configured to receive a video image and a captured date captured by the imaging unit, and to manage the video image in association with the captured date. The video image management unit obtains the operational information and the obtained date from the wireless management unit, manages the video image associated with a captured date which matches with the obtained date, in association with the operational information, and extracts the video image and the operational information associated with a predetermined date.
