DAS Virtualization for Multi-Operator Resource Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current distributed antenna systems (DAS) face challenges in efficiently managing and allocating resources across multiple wireless communications service providers, leading to complexities in coverage area expansion and service management.
Innovation Solution
The implementation of a DAS management virtualization system that establishes virtual systems, allowing for the assignment of physical resources to each operator, with a northbound interface driver managing these resources and providing operator-specific interfaces for independent management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional DAS manages resources for multiple operators manually, then resource allocation is possible, but system complexity and management difficulty increase significantly
Solution Approach 1:
The system segments the physical DAS resources into separate virtual DAS instances, each dedicated to a specific operator. This segmentation allows independent management of each operator's resources while sharing the same physical infrastructure, thereby reducing management complexity through virtualization
Solution Approach 2:
The system creates virtual copies of DAS functionality through software-defined networking. Each operator receives a virtual DAS instance that is a logical copy of the physical system, allowing independent configuration and management without increasing physical system complexity
2Productivity
If physical DAS resources are shared across multiple operators, then infrastructure utilization improves, but resource allocation precision and operator isolation deteriorate
Solution Approach 1:
The system divides shared physical resources into isolated virtual resource pools for each operator. This segmentation enables precise resource allocation control for each operator while maintaining shared infrastructure, achieving both high utilization and precise allocation through virtualization boundaries
Solution Approach 2:
Each virtual DAS instance provides operator-specific resource allocation policies and characteristics while sharing the same physical hardware. This local quality approach allows customized resource management for each operator without affecting the shared infrastructure's overall efficiency

AI summary
In one embodiment, a system comprises: a central area node; access points coupled to the central area node and configured to radiate a remote downlink RF signal and receive a remote uplink RF signal; and a controller configured to execute code for a management virtualization system that includes a virtual system controller function configured to establish a plurality of virtual systems and assign physical resources of the system to each of the virtual systems. The management virtualization system includes a northbound interface driver that defines a first virtualized operator interface configured to manage a first set of physical resources assigned to a first virtual system, and a second virtualized operator interface configured to manage a second set of physical resources assigned to a second virtual system.
