Deploying 5G O-RAN RIC on AWS
Publication date: June 16, 2022 (Diagram history)
With this architecture, you can deploy the Open Radio Access Network (O-RAN) Radio Intelligent Controller (RIC) on AWS. The RIC optimizes control algorithms for load balancing, mobility management, multi-connection control, quality of experience (QoE) management, and network energy saving. The solution uses Amazon Elastic Kubernetes Service for compute and Amazon SageMaker AI for machine learning (ML) model lifecycle operations.
Deploying 5G O-RAN RIC on AWS diagram
The following steps describe the RIC components and data flow for this architecture:
-
Use the E2 O-RAN specified Stream Control Transmission Protocol (SCTP) over Internet Protocol (IP) interface for near-real-time (10 ms to 1 s) data collection and control loops.
-
Monitor and control the Central Units (CUs) and Distributed Units (DUs) by using the near-real-time RIC. Persist data with NoSQL database instances by using Amazon EBS storage attached to Amazon EKS nodes on AWS Outposts or in AWS Local Zones.
-
Host apps on the near-real-time RIC that provide services such as QoE prediction and proactive, closed-loop network optimization.
-
Include SageMaker AI inference endpoints running ML models trained, updated, and deployed on Amazon EC2 instances by the non-real-time RIC in near-real-time and non-real-time apps.
-
Use the A1 O-RAN specified REST HTTP/TCP/IP interface to deploy policy-based guidance for the near-real-time RIC and to manage ML models used in RIC apps.
-
Use the O1 O-RAN REST HTTP/TCP/IP interface for non-real-time (1 s+) control loops, such as static Radio Resource Management (RRM) policies.
-
Provide guidance, enrichment information, and management of ML models by using the non-real-time control loop.
-
Store raw data, processed data, inference results, trained models, and Amazon EBS backup snapshots in an Amazon Simple Storage Service-backed AWS Lake Formation data lake on the non-real-time RIC.
-
Use SageMaker AI to develop, train, and deploy ML models used by the near-real-time and non-real-time apps.
