QoS Synchronization via Bandwidth Anomaly Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network architectures face challenges in managing quality of service (QoS) due to inadequate resource management, especially in mobile wireless environments where bandwidth fluctuations and link errors are common, leading to inconsistent user experiences and inefficient resource utilization.
Innovation Solution
A system and method that synchronizes QoS by detecting bandwidth anomalies in radio links, aggregating this information into QoS control signals, and communicating these signals across the network to adjust subscriber QoS settings dynamically, integrating airlink and transport domain mechanisms to ensure consistent QoS across disparate networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If independent carrier Ethernet QoS mechanisms are used, then QoS control in transport domain is improved, but end-to-end QoS consistency deteriorates
Solution Approach 1:
The patent combines carrier Ethernet QoS mechanisms with radio access bearer QoS mechanisms into a unified end-to-end QoS management system. The aggregation provider edge device correlates QoS parameters from both domains, translating between different QoS frameworks to ensure consistent QoS delivery across the entire network path from user equipment through radio access to transport network.
Solution Approach 2:
The aggregation provider edge device acts as an intermediary between the transport domain and radio access domain. It receives status signals from both domains, detects bandwidth anomalies, and generates QoS control signals that coordinate QoS enforcement across both independent mechanisms, ensuring they work together rather than in isolation.
2Ease of operation
If radio access bearer QoS mechanisms are used, then radio interface QoS management is improved, but overall network QoS reliability deteriorates
Solution Approach 1:
The system implements feedback loops where the aggregation provider edge device continuously monitors status signals from radio links, detects bandwidth anomalies, and adjusts QoS control signals accordingly. This closed-loop control ensures that radio access bearer QoS mechanisms are coordinated with transport domain QoS, improving overall network QoS reliability while maintaining ease of radio interface management.
3Adaptability or versatility
If current wireless network architectures are used, then existing QoS mechanisms are maintained, but bandwidth demand and latency requirements cannot be accommodated
Solution Approach 1:
The patent implements dynamic QoS adjustment where the aggregation provider edge device continuously monitors network conditions and status signals, detecting bandwidth anomalies in real-time. QoS control signals are dynamically modified based on detected anomalies and current bandwidth demands, allowing the system to adapt to varying latency requirements and bandwidth demands while maintaining compatibility with existing QoS mechanisms.
