Service-Aware Wireless Resource Routing for QoS Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern wireless communication systems face congestion and quality of service (QoS) issues due to overutilization of licensed resources, particularly when there is a high demand for wireless resources, leading to noticeable latency and poor user experience for QoS-sensitive traffic.
Innovation Solution
Implementing a service-aware approach that routes Quality-of-Service (QoS)-sensitive data traffic over licensed wireless resources while routing non-QoS-sensitive traffic over shared wireless resources, such as the CBRS band, when the quality metric, like Bit Error Rate (BER), is high, thereby reducing the demand on licensed resources and maintaining a better quality of experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all data traffic is routed over licensed wireless resources, then reliability of service delivery is improved, but congestion increases and productivity decreases due to overutilization
Solution Approach 1:
The patent segments data traffic into QoS-sensitive and non-QoS-sensitive categories, routing each type over appropriate wireless resources. QoS-sensitive traffic is routed over licensed resources to maintain reliability, while non-QoS-sensitive traffic is routed over shared resources to improve overall network productivity and reduce congestion.
Solution Approach 2:
The patent implements dynamic routing that adapts to current network conditions by monitoring quality metrics of shared resources. When shared resources meet quality thresholds, non-QoS-sensitive traffic is routed over them; when thresholds are not met, traffic is routed over licensed resources, creating a flexible system that balances reliability and productivity.
2Productivity
If shared wireless resources are used to increase capacity, then productivity is improved, but quality of service deteriorates when quality metrics are poor
Solution Approach 1:
The patent employs feedback mechanisms by continuously monitoring quality metrics of shared wireless resources. This feedback information is used to dynamically adjust routing decisions, ensuring that non-QoS-sensitive traffic is only routed over shared resources when quality thresholds are met, thereby maintaining service quality while maximizing network capacity.
Solution Approach 2:
The patent introduces a routing mechanism that acts as an intermediary between traffic sources and wireless resources. This intermediary evaluates quality metrics and makes intelligent routing decisions, selecting appropriate resources based on traffic type and current conditions, thus balancing capacity utilization with service quality maintenance.
3Reliability
If licensed wireless resources are reserved for QoS-sensitive traffic, then quality of service is improved, but loss of time increases due to reduced available resources for other traffic
Solution Approach 1:
The patent applies local quality by providing different service levels to different traffic types. QoS-sensitive traffic receives prioritized handling over licensed resources with guaranteed performance, while non-QoS-sensitive traffic utilizes shared resources. This differentiated approach ensures low latency for critical traffic without completely blocking other traffic from accessing licensed resources when needed.

AI summary
Systems, methods, and devices can be used to perform service-aware utilization of shared wireless resources. In various instances, a quality metric (e.g., a Bit Error Rate (BER)) of a shared wireless resource is determined. Requested services can be provided based at least partly on the quality metric and the type of services being requested. For example, when the quality metric exceeds a threshold and the requested services are for Quality of Service (QoS)-sensitive services (e.g., Guaranteed Bit Rate (GBR) services), the services can be provided at least partially via a licensed wireless resource. However, when the quality metric does not exceed the threshold, and/or the requested services are for non-QoS-sensitive services (e.g., non-GBR services), the services can be provided via the shared wireless resource.
