Radio Manager Unit for Multi-Tenant Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio access networks face challenges in efficiently managing and allocating resources to multiple tenants or operators, particularly in optical fronthaul networks, which limits flexibility and scalability.
Innovation Solution
A radio manager unit is introduced to connect with a transport control unit and a radio control unit, allowing for the configuration and allocation of transport network and baseband processing resources to tenants, providing a virtualized view of resources and enabling dynamic resource management and sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the optical fronthaul network is opened to multiple tenants/operators, then network scalability and resource utilization are improved, but device complexity and management overhead increase
Solution Approach 1:
The patent segments the fronthaul network into multiple isolated virtual networks (V-Nets), each dedicated to a specific tenant or operator. This segmentation allows multiple tenants to share the physical infrastructure while maintaining logical isolation, thereby improving network scalability without proportionally increasing management complexity since each V-Net can be managed independently
Solution Approach 2:
The patent introduces a virtualization layer as an intermediary between the physical fronthaul network and multiple tenants. This virtualization layer abstracts the complex physical network resources and presents simplified virtual network interfaces to tenants, reducing management overhead while enabling multi-tenant support
2Use of energy by moving object
If resources are dynamically shared among multiple cells, then energy efficiency and resource utilization are improved, but coordination complexity and control overhead increase
Solution Approach 1:
The patent merges the control functions for multiple cells into a centralized baseband processing unit. This consolidation allows dynamic resource sharing and coordination across multiple cells while reducing overall system complexity compared to distributed control architectures, as the centralized unit can optimize resource allocation across all served cells simultaneously
Solution Approach 2:
The baseband processing unit is designed with multi-functionality to handle resource coordination and sharing across multiple cells simultaneously. This universal control mechanism enables energy-efficient dynamic resource allocation without requiring separate control logic for each cell, thereby reducing coordination complexity
