O-RAN Database Sharing Radio Access Network Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Open Radio Access Networks (O-RAN), the lack of direct component-to-component interfaces leads to delays in data transmission, which hampers the performance of neural networks that rely on timely data access for real-time operations, such as beamforming optimization.
Innovation Solution
A database system is introduced that allows all components of the O-RAN network to subscribe and periodically send or receive data, enabling direct access and minimizing delays by using a hardware interface like Ethernet for data sharing among components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If components use indirect interfaces for data transmission, then system architecture is simplified, but transmission delay increases
Solution Approach 1:
The patent introduces a shared memory buffer as an intermediary mechanism between components. Instead of direct point-to-point connections, components write data to the shared buffer and read from it, eliminating the need for complex direct interfaces while reducing transmission delay through local memory access.
Solution Approach 2:
The patent merges multiple data transmission paths into a single shared memory space. Multiple components access the same memory buffer concurrently, combining what would otherwise be separate communication channels into one unified data sharing mechanism, thereby simplifying architecture and reducing latency.
2Adaptability or versatility
If more base stations and radio units are installed, then network coverage and user capacity increase, but computational and memory resources required for information processing increase
Solution Approach 1:
The patent implements a shared memory buffer that creates a copy of network information in a centralized location. Multiple components read from this shared copy rather than maintaining separate data structures, reducing the total computational and memory resources needed while supporting expanded network coverage.
Solution Approach 2:
The shared memory buffer serves multiple functions simultaneously: it stores network information, provides fast local access for multiple components, and acts as a synchronization mechanism. This multi-functionality reduces the overall resource requirements compared to dedicated storage and communication paths for each component.
