Solution Overview
Problem
Current cellular network architectures are inflexible and closed, limiting the ability of telecom operators to dynamically control and optimize network performance, especially in real-time, due to rigid separation of entities involved in network deployment and lack of programmability.
Innovation Solution
The implementation of an Open Radio Access Network (O-RAN) architecture with a Radio Access Network (RAN) Intelligent Controller (RIC) that includes a data-driven logic unit, utilizing autoencoders and deep reinforcement learning agents to dynamically configure network elements based on real-time performance metrics, enabling agile control and optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional closed cellular network architecture is used, then network stability and vendor control are maintained, but network flexibility, programmability, and real-time optimization capability are limited
Solution Approach 1:
The patent segments the traditional monolithic network architecture into modular components: RIC (RAN Intelligent Controller), xApps (application layer), rApps (real-time layer), and O-RAN interface layers. This segmentation enables independent development, deployment, and optimization of network functions, directly improving network flexibility while maintaining manageable complexity through standardized interfaces.
Solution Approach 2:
The RIC acts as an intermediary layer between the network infrastructure and optimization algorithms. It provides standardized interfaces (E2 interface) that mediate between traditional network elements and new intelligent applications, enabling flexibility without requiring fundamental changes to existing network infrastructure, thus resolving the contradiction between adaptability and complexity.
2Productivity
If manual network configuration and control methods are used, then system reliability is maintained, but real-time optimization capability and operational efficiency are reduced
Solution Approach 1:
The system enables self-service through automated xApps that continuously monitor network performance metrics, autonomously analyze data using machine learning algorithms, and automatically adjust network parameters without manual intervention. This automation dramatically improves optimization efficiency while reducing the operational burden on network administrators.
Solution Approach 2:
The patent implements closed-loop feedback mechanisms where performance metrics are continuously collected from the network, processed by the RIC, and used to generate optimization actions that are fed back to network elements. This automated feedback loop enables real-time optimization, replacing manual control methods and significantly improving productivity.
3Adaptability or versatility
If multi-vendor network equipment is deployed, then network interoperability and choice are improved, but system integration complexity and coordination difficulty increase
Solution Approach 1:
The O-RAN architecture provides universal interfaces and standardized protocols that enable multi-vendor interoperability. The RIC and xApps can work with equipment from different vendors through standardized E2 interfaces, allowing operators to choose the best equipment from multiple vendors without facing integration nightmares, thus achieving versatility without proportionally increasing complexity.
Data Source
AI summary
A radio access network (RAN) intelligent controller (RIC) and corresponding method may be implemented within RAN and in next-generation cellular networks to improve performance. The RIC comprises an interface to a RAN and further comprises a data-driven logic unit. The data-driven logic unit (i) produces, based on data received from the RAN via the interface, a representation describing a state of the RAN and (ii) based on the representation describing the state, instructs an action associated with at least one network element. The interface transmits a message based on the action instructed. The message is to be routed to the at least one network element. The representation is based on a context of the RAN. The message transmitted enabling re-configuration of the at least one network element. The re-configuration improves performance of the at least one network element within the context.
