2020年11月23日 · What is a 5G Open Radio Access Network (O-RAN)? An Open Radio Access Network (O-RAN) is a disaggregated approach to deploying mobile fronthaul and midhaul networks built entirely on cloud native principles. O-RAN underscores streamlined 5G RAN performance objectives through the common attributes of efficiency, intelligence and versatility.

O-RAN SC architecture follows O-RAN Alliance defined architecture. Figure 1: O-RAN architecture overview. In the O-RAN architecture, the radio side includes Near-RT RIC, O-CU-CP, O-CU-UP, O-DU, and O-RU. The management side includes Service Management and Orchestration Framework that contains a Non-RT-RIC function.

Empowered by principles of intelligence and openness, the O-RAN Architecture is the foundation for building a virtualized RAN on open hardware and cloud, with embedded AI-powered radio control.

Members and Participants of the O-RAN ALLIANCE bring their experts to jointly develop technical documents, defining interfaces, functions or processes of open, intelligent, virtualized and interoperable Radio Access Networks.

2021年4月22日 · Understand what Radio Access Network (RAN) & Open Radio Access Network (O-RAN or Open-RAN) is, its Architecture, Benefits and How O-RAN differs from V-RAN through this blog. Industry Telcos

2021年6月23日 · After having looked at the O-RAN Alliance approach, philosophy, timelines, and architecture in brief, it is time to take a slightly more in-depth look at the O-RAN architecture.

The O-RAN architecture addresses traditional RAN challenges by creating a disaggregated and virtualized network with standard interfaces. In doing so, it delivers four key benefits: Transformation • Enabling more open, virtualized, and fully …

An Open Radio Access Network (ORAN) is a nonproprietary version of the Radio Access Network (RAN) system that allows interoperation between cellular network equipment provided by different vendors.

We provide a deep dive of the O-RAN specifications, describing its architecture, design principles, and the O-RAN interfaces. We then describe how the O-RAN RAN Intelligent Controllers (RICs) can be used to effectively control and manage 3GPP-defined RANs.

2021年5月21日 · The first section provides an introduction to O-RAN, followed by architecture discussion, RAN-intelligent controller description, and overview of use cases.
