Central QoS Manager for Dynamic Resource Allocation in 5G Subnetworks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern communication networks, particularly 5G, face challenges in managing quality of service across heterogeneous sub-networks with different radio access technologies, requiring an efficient mechanism to allocate resources and ensure service quality.
Innovation Solution
A communication arrangement with a central quality of service manager that assigns quality of service classes to sub-networks, controlling communication resources such as bandwidth and latency to meet specific service requirements, and dynamically allocates resources among baseband and radio access units to maintain agreed-upon quality standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a central quality of service manager controls communication resources according to quality of service classes, then quality of service standards are met, but device complexity increases
Solution Approach 1:
A central quality of service manager is introduced as an intermediary component that coordinates communication resources across multiple baseband units and radio access units. This central manager receives quality of service class information from the core network and distributes appropriate resource allocations to subordinate units, thereby ensuring quality of service standards are met while distributing the complexity burden rather than concentrating it in a single baseband unit.
2Adaptability or versatility
If communication resources are allocated according to quality of service classes, then service differentiation is achieved, but device complexity increases
Solution Approach 1:
Different quality of service classes are applied locally to different data streams and different baseband units based on their specific requirements. The system identifies the quality of service class for each data stream and allocates communication resources accordingly, allowing high-priority traffic to receive more resources while low-priority traffic receives fewer resources. This localized application of quality of service principles enables service differentiation without requiring every component to handle all possible service types.
3Adaptability or versatility
If multiple quality of service classes are supported across heterogeneous sub-networks, then adaptability increases, but device complexity increases
Solution Approach 1:
The system segments the network into heterogeneous sub-networks, each capable of supporting multiple quality of service classes. Each baseband unit and radio access unit is designed to handle multiple quality of service classes, but the actual implementation of which classes are active is determined by the central quality of service manager based on network conditions and service requirements. This segmentation allows adaptability across the system while keeping individual device complexity manageable.
