Radio QoS Negotiation Across Multiple Communication Technologies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks struggle to provide reliable Quality of Service (QoS) guarantees for safety-critical applications, leading to inefficiencies and potential safety risks due to reactive measures after QoS degradation and lack of end-to-end control mechanisms across multiple communication technologies.
Innovation Solution
A mechanism for devices and network equipment to negotiate and exchange QoS requirements, including reliability metrics, allowing the network to propose feasible alternatives if initial requests cannot be met, ensuring efficient resource allocation and meeting safety-critical application needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network provides QoS guarantees for safety-critical applications, then reliability is improved, but device complexity increases due to multiple communication technologies and lack of end-to-end control mechanisms
Solution Approach 1:
The patent introduces a QoS management entity as an intermediary component that coordinates QoS parameters across multiple communication technologies. This mediator translates application-level QoS requirements into technology-specific configurations, simplifying the overall system complexity while maintaining reliability through centralized control.
Solution Approach 2:
The patent creates a universal QoS management mechanism that works across different communication technologies (e.g., cellular, Wi-Fi, Bluetooth). This multi-functional approach allows a single standardized interface to handle diverse communication protocols, reducing device complexity while ensuring reliable QoS guarantees regardless of the underlying technology.
2Ease of operation
If reactive measures are implemented after QoS degradation, then ease of operation is maintained, but productivity decreases due to safety risks and inefficiencies
Solution Approach 1:
The patent implements preliminary QoS monitoring and prediction mechanisms that detect potential QoS degradation before it occurs. By proactively adjusting QoS parameters in advance, the system prevents safety risks and inefficiencies rather than reacting after problems arise, thereby maintaining both ease of operation and high productivity.
3Adaptability or versatility
If multiple communication technologies are used, then adaptability is improved, but loss of information increases due to lack of end-to-end control
Solution Approach 1:
The patent establishes end-to-end feedback loops that continuously monitor QoS parameters across multiple communication technologies. This feedback mechanism ensures that QoS control information is maintained and transmitted accurately throughout the entire communication chain, preventing information loss while preserving the adaptability benefits of using multiple technologies.
