Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public safety communication networks face network congestion and quality of service conflicts during emergency situations, particularly when determining and sharing travel routes with mobile devices, leading to inefficient data exchange and rapid battery drain due to repeated communication attempts in poor conditions.
Innovation Solution
A method and system for dynamically assigning quality of service to mobile communications devices based on their location deviation from a travel route, allowing for reallocation of resources and ensuring timely and reliable data exchange by adjusting the quality of service from high to low and back to high as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If broadband connection is used to ensure timely map and location data exchange, then data exchange reliability is improved, but network congestion and quality of service conflicts worsen
Solution Approach 1:
The patent implements dynamic quality of service assignment that adapts to real-time communication conditions. The system monitors network status and device location deviation from travel routes, then dynamically adjusts QoS parameters (bit rate, transmission delay, error rates) to optimize data exchange reliability while managing network congestion during emergency situations.
Solution Approach 2:
The patent applies different quality of service levels to different mobile devices based on their specific conditions. Devices are assigned individual QoS parameters according to their location deviation from the travel route and current network conditions, ensuring that critical communications receive prioritized service while reducing overall network load.
2Reliability
If repeated communication attempts are made to complete data exchange in poor conditions, then data exchange reliability is improved, but battery drain worsens
Solution Approach 1:
The system continuously monitors communication status and network conditions, using this feedback to dynamically adjust QoS parameters. When communication conditions deteriorate, the system preemptively reduces transmission requirements and optimizes data exchange parameters, preventing repeated failed attempts and the associated battery drain while maintaining reliable data delivery.
Solution Approach 2:
The patent changes communication parameters (bit rate, transmission delay tolerance, error rate thresholds) based on real-time conditions. By adapting these parameters to current network status and device location, the system achieves reliable data exchange without requiring repeated communication attempts, thereby reducing energy consumption.
3Reliability
If high quality of service is assigned to all devices, then communication reliability is improved, but network resource allocation worsens
Solution Approach 1:
The patent implements differentiated quality of service assignment where each mobile device receives QoS parameters tailored to its specific conditions. Devices are evaluated based on their location deviation from travel routes and current network conditions, with critical devices receiving higher QoS and less critical devices receiving reduced QoS, thereby optimizing overall resource allocation efficiency.
Solution Approach 2:
The system dynamically adjusts QoS assignments based on real-time network status and device conditions. As network conditions change or device locations shift, the system recalibrates QoS parameters to maintain communication reliability for critical devices while improving resource allocation efficiency across the network.

AI summary
A method of managing communications of a mobile communications device. In one embodiment, the method includes receiving a travel route with the mobile communications device and assigning a first quality of service to the mobile communications device in response to receiving the travel route. The method also includes determining a current location of the mobile communications device, determining a positional deviation of the mobile communications device from the travel route based on the current location of the mobile communications device, and assigning a second quality of service to the mobile communications device when the positional deviation of the mobile communications device exceeds a predetermined threshold. The second quality of service being higher than the first quality of service.
