Dynamic QoS Control for Network Bandwidth Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios with multiple co-located users, such as public safety situations, network bandwidth is overwhelmed due to unused devices and applications continuing to consume resources, leading to degraded service for actively used devices.
Innovation Solution
A method and apparatus for dynamically controlling Quality of Service (QoS) by determining if a device or application is actively being used, adjusting QoS accordingly to allocate resources more efficiently, using techniques like GPS, Bluetooth, and facial detection to assess usage and adjust bandwidth allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices continue to run applications when not being used by officers, then applications can maintain readiness and respond quickly when needed, but network bandwidth is wasted and QoS is degraded for other active devices
Solution Approach 1:
The system dynamically adjusts QoS parameters based on real-time device usage status. When a device is detected as unused (through sensor data, GPS location changes, or device status reports), the system automatically reduces its QoS allocation. When the device is detected as active, QoS is restored to previous levels, enabling flexible resource allocation that balances readiness with bandwidth conservation
Solution Approach 2:
The system changes key QoS parameters (bandwidth allocation, priority levels, resource reservations) based on device usage state. By monitoring whether devices are actively being used by officers, the system adjusts these parameters to reduce bandwidth consumption for unused devices while maintaining adequate resources for active devices and applications
2Adaptability or versatility
If multiple co-located users each carry multiple devices, then each user can access appropriate tools and applications, but network bandwidth is overwhelmed and service quality degrades
Solution Approach 1:
The system applies different QoS treatment to different devices based on their individual usage status rather than treating all devices uniformly. Each device's QoS is independently adjusted according to whether it is currently being used by an officer, allowing the network to optimize resource distribution across multiple co-located users and devices
Solution Approach 2:
The system implements feedback mechanisms to monitor device usage status and automatically adjust QoS allocations. By continuously gathering information about which devices are actively being used versus which are unused, the system can dynamically rebalance network resources to maintain service quality even when multiple devices are present at the same location
3Duration of action of moving object
If devices left in vehicles continue to run applications, then applications can quickly resume when officers return, but valuable bandwidth is consumed by unused devices
Solution Approach 1:
The system applies partial QoS reduction to devices that appear unused based on location data (such as devices remaining in vehicles). Instead of completely terminating applications, the system maintains them with reduced resource allocation, allowing quick resumption when needed while consuming fewer bandwidth resources during periods when officers are away from their vehicles

AI summary
A method and apparatus for dynamically controlling quality of service (QoS) is provided. During operation, a QoS manager will determine if a device is currently being used by an individual. Determination can be carried out by facial detection or motion detection. The QoS of the device will then be tailored based on whether or not the device is currently being used by the individual. Devices that may be running applications, yet unused by anyone in the vicinity may have their QoS reduced. This will allow the QoS to be increased for devices that are currently being used.
