Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation applications on user devices struggle to maintain continuous use of interactive applications like video conferencing during travel due to network congestion, maintenance, and quality of service issues, as they rely on reactive solutions that cannot predict or mitigate real-time QoS variations.
Innovation Solution
A network-assisted navigation system that determines a path based on network-level information about congestion and quality of service, using a navigation controller to select routes that avoid areas of poor coverage and allocate dedicated resources for priority applications, ensuring continuous and high-quality connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If navigation applications use reactive solutions to handle network issues, then device complexity is reduced, but reliability of interactive applications deteriorates due to inability to predict or mitigate real-time QoS variations
Solution Approach 1:
The patent introduces a network controller as an intermediary component that mediates between the navigation application and the network infrastructure. This controller proactively monitors network QoS parameters, predicts potential disruptions, and adjusts navigation routes before service degradation occurs, thereby improving reliability without requiring complex reactive mechanisms in the end-user device
Solution Approach 2:
The system performs preliminary actions by proactively assessing network conditions and predicting future QoS variations before they impact service delivery. The network controller提前 identifies potential network disruptions and pre-adjusts navigation routes, preventing service degradation rather than reacting to it after occurrence
2Reliability
If navigation applications prioritize maintaining continuous connectivity, then reliability improves, but loss of time increases due to route changes and network switching
Solution Approach 1:
The network controller performs preliminary assessment of network conditions along potential navigation routes, identifying areas with poor coverage or anticipated congestion before the user device travels there. By proactively selecting optimal routes in advance, the system maintains continuous connectivity without requiring time-consuming mid-journey route changes
Solution Approach 2:
The system implements continuous feedback loops where the network controller monitors real-time QoS parameters along the navigation route and dynamically adjusts the path to maintain optimal connectivity. This feedback mechanism ensures continuous service delivery while minimizing disruptions and associated time losses
3Measurement precision
If the system provides detailed network quality monitoring, then measurement precision improves, but device complexity increases due to additional sensing and processing requirements
Solution Approach 1:
The network controller serves as an intermediary that performs detailed network quality monitoring and measurement centrally, rather than requiring complex sensing and processing capabilities in each user device. The controller collects QoS data from network infrastructure elements and provides processed information to navigation applications, achieving high measurement precision without increasing device complexity
Solution Approach 2:
The patent replaces the mechanical approach of equipping user devices with complex network sensing and processing hardware with a software-based solution where the network controller performs monitoring and analysis remotely, substituting physical device complexity with centralized computational capabilities
