Conclusion

The O-RAN architecture is gaining interest from wireless network operators for implementing 5G networks. Driven by the O-RAN alliance with more than 230 operators and vendors, the O-RAN architecture defines a disaggregate RAN structure with full inter-operability, using cloud infrastructure as a common network platform.

This paper outlines O-RAN on AWS, and what the O-RAN components, including the RIC, the SMO, the O-CU, and the O-DU would look like on the AWS Cloud infrastructure. The breadth and depth of AWS services can also benefit O-RAN. AWS services and infrastructure can be not only a place to easily implement a virtualized 5G network, but also a unified management platform to control all the O-RAN components via a single pane of glass. The AWS programmable cloud can enable important 5G use cases and features, which include the edge cloud for low-latency applications, RIC network optimization, network slicing, DevOps, and continuous evolution. In addition, the AWS Cloud has a wide range of open ecosystems, with various partners and proven O-RAN components.

As specified in the O-RAN architecture, the cloud platform by AWS with fully programmable management and a wide-open ecosystem introduces the multi-vendor model, and multiple ways of efficient automation to the wireless operators who pursuit business differentiation and leadership in the 5G era. The operators on the AWS Cloud can focus their business applications and ideas to monetize the network and enhance end users' experience. The AWS O-RAN Cloud, together with the operators, accelerates time-to-market, reduces TCO, and brings the flexibility and ability to automate network operations and new service rollouts, to reinvent 5G networks and reimagine the customer experience.
