Wireless Gateway Immobile Device Detection for Network Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks, immobile devices such as TVs and IoT devices overload wireless extenders and MAP control devices, leading to delayed roaming and steering operations, which negatively affect the quality of service (QoE).
Innovation Solution
A gateway device is introduced to monitor station metrics data, identify immobile devices based on specific thresholds, and transmit instructions to wireless extenders to reduce data collection and reporting for these devices, thereby alleviating the burden on the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless extenders collect and report station metrics data for all client devices, then complete network monitoring is achieved, but the wireless extenders and MAP control device become overloaded
Solution Approach 1:
The patent applies local quality by differentiating data collection strategies based on device type. Mobile devices receive full monitoring with continuous station metrics data collection, while immobile devices receive reduced monitoring. This localized approach to data collection quality resolves the contradiction by maintaining comprehensive monitoring where needed while reducing burden where unnecessary.
Solution Approach 2:
The patent segments client devices into mobile and immobile categories based on mobility detection algorithms. This segmentation allows the system to apply different data collection and reporting policies to different device groups, thereby reducing overall network device load while maintaining necessary monitoring capabilities for devices that actually require it.
2Productivity
If wireless extenders perform timely reporting operations for all devices, then roaming operations are optimized, but immobile devices unnecessarily consume network resources
Solution Approach 1:
The patent extracts immobile devices from the set of devices requiring full monitoring and reporting operations. By identifying and separating these devices based on mobility characteristics, the system eliminates unnecessary data collection and reporting for devices that do not participate in roaming operations, thereby reducing data volume while preserving roaming optimization for mobile devices.
Solution Approach 2:
The patent applies partial action by providing full monitoring and reporting only to mobile devices that require it, while applying reduced monitoring to immobile devices. This partial approach avoids excessive data collection for devices that cannot benefit from roaming operations, optimizing the balance between roaming efficiency and resource consumption.
3Reliability
If all client devices are monitored with the same data collection frequency, then uniform service quality is maintained, but immobile devices cause unnecessary overloading
Solution Approach 1:
The patent implements local quality by applying different monitoring intensities to different device types. Mobile devices receive high-frequency monitoring with complete station metrics data collection, while immobile devices receive lower-frequency monitoring with reduced data collection. This resolves the contradiction by maintaining service quality uniformity for devices that need it while reducing processing burden through localized differentiation.

AI summary
An apparatus, method, and computer-readable recording medium perform optimized data collection in a wireless network. The wireless network communicatively interconnects a gateway device having a network controller, one or more wireless extenders, and one or more client devices. The gateway device receives polling responses from the one or more wireless extenders and periodically monitors station metrics data for the one or more client devices based on the polling responses. The gateway device determines which of the one or more client devices is an immobile device based on the station metrics data, and transmits an instruction to at least one wireless extender for modifying collection or reporting of the station metrics data for any client device determined to be an immobile device.
