ONF launches 5G SD-RAN Project

The Open Networking Foundation (ONF) has launched an SD-RAN project with the aim of building an open source Near Real-Time RAN Intelligent Controller (nRT-RIC) compatible with the O-RAN architecture as well ONF’s existing base cloud-native solutions leveraging disaggregation and whitebox hardware.

ONF said its goal is to foster open source software platforms and multi-vendor solutions for mobile 4G and 5G RAN deployments.

Central to the project is the development of an open source near-real time RIC called µONOS-RIC (pronounced “micro-ONOS-RIC”).

µONOS is a microservices-based SDN controller created by the refactoring and enhancement of ONOS, the leading SDN controller for operators in production tier-1 networks worldwide.  µONOS-RIC is built on µONOS, and hence features a cloud-native design supporting active-active clustering for scalability, performance and high availability along with the real-time capabilities needed for intelligent RAN control. The O-RAN ALLIANCE E2 interface is used to interface between µONOS-RIC and vendor supplied RAN RU/DU/CU RAN components.

Carriers would be able to run new "xApps" on top of the µONOS-RIC.  These open xApps could provide functionality that traditionally has been implemented in vendor-proprietary implementations, including providing visibility and control over the RAN.

Significantly, the ONF's SD-RAN project is backed by AT&T, China Mobile, China Unicom, Deutsche Telekom, Facebook, Google, Intel, NTT, Radisys and Sercomm.

A working skeleton prototype of the µONOS-RIC controller is already running above a RAN emulation platform through the E2 interface.  ONF has demonstrated handover and load balancing at scale, supporting over 100 base stations and 100,000 user devices with less than 50ms handover latency (less than 10ms latency for 99% of all handovers). Field trials are expected by early 2021.

“AT&T strongly supports the development of specifications and components that can help drive openness and innovation in the RAN ecosystem. The O-RAN ALLIANCE’s specifications are enabling the ecosystem, with a range of companies and organizations creating both open source and proprietary implementations that are bringing the open specifications to life. The ONF SD-RAN project, along with the O-RAN OSC, will expand the ecosystem with an nRT-RIC that can support xApps and help demonstrate their interoperability. This project will help accelerate the transition to an open RAN future,” stated Andre Fuetsch, President and Chief Technology Officer, AT&T Labs.

“Google is an advocate for SDN, disaggregation and open source, and we are excited to see these principles now being applied to the RAN domain. ONF’s SD-RAN project’s ambition to create an open source RIC can help invigorate innovation across the mobile domain, said Ankur Jain, Distinguished Engineer, Google.

ONF's Aether targets Enterprise 5G/LTE-Edge-Cloud-as-a-Service

The Open Networking Foundation (ONF) announced Aether – the first open-source platform for delivering Enterprise 5G/LTE-Edge-Cloud-as-a-Service.

Aether (pronounced ‘ee-ther’) provides mobile connectivity and edge cloud services for distributed enterprise networks, all provisioned and managed from a centralized cloud.


Aether leverages existing work from ONF including the CORD and ONOS platforms. It can be run in a Kubernetes environment, and it simultaneously supports deployment on licensed (4G/5G) and unlicensed (CBRS) spectrum.

“Aether opens the door for enterprises to rapidly deploy 5G and edge cloud services to help power their digital transformations. This can be done with a variety of flexible business models including in collaboration with telco operators, cloud operators, and third party providers. It offers the flexibility to utilize a wide range of bands including 5G, licensed bands, and CBRS. This cloud-enabled platform turns mobile connectivity and enterprise mobile edge cloud capabilities into a cloud-managed service, simplifying deployment and operations while delivering scalable and cost-effective services,” states Guru Parulkar, Executive Director, ONF & Executive Director, Stanford Platform Lab.

ONF already has a modest Aether pilot production network supporting edge cloud services running at two ONF offices, Intel Labs, and at other sites. This pilot is centrally managed and controlled from public cloud, with Aether Edge installations at each site. The entire deployment is maintained by ONF and ONF members using a distributed CI/CD DevOps development pipeline.

As with all ONF projects, Aether is backed by ONF’s operator partners AT&T, China Unicom, Comcast, Deutsche Telekom, Google, NTT Group and Turk Telekom. Additionally, ONF, Intel, GSLab, Infosys, and Accelleran are actively collaborating as a distributed DevOps team enhancing and maintaining Aether.

Keysight tests O-RAN with China's Cambridge Industries Group

Keysight Technologies announced inter-operability development testing (IODT) of O-RAN radio units (O-RUs) in collaboration with Cambridge Industries Group (CIG), a leading original design manufacturer (ODM), headquartered in Shanghai, China.

The testing was accomplished using CIG’s O-RU and Keysight’s Open RAN Studio, signal source and analyzer solutions to create an environment for 5G new radio (NR) modulation analysis. As a result, CIG and other vendors of O-RUs can accelerate design verification of products based on specifications set by the O-RAN Alliance. CIG is part of a network infrastructure ecosystem that is using O-RAN fronthaul interfaces to unlock the full potential of an open RAN architecture.

“We rely on partners such as Keysight to effectively develop and validate open RAN standards-based network elements, including small cells and O-RAN compliant radio and distributed units,” said Haibo Zhao, founder, chief technology officer (CTO) at CIG. “Working with Keysight, with cross-domain expertise, enables CIG to derive insights critical in the design and manufacturing of a flexible infrastructure that serves diverse use cases for consumers and vertical industries.”

“Together with key partners such as CIG, we are advancing the development of a disaggregated, virtualized network architecture based on O-RAN specifications,” said Giampaolo Tardioli, vice president of Keysight and general manager of Keysight's Network Access Group. “The future of pervasive wireless connectivity requires end-to-end performance verification of 5G network elements across multiple domains including, radio frequency (RF), mmWave and O-RAN protocol.”

Nokia accelerates push into Open RAN

Nokia is ramping up the adoption of Open RAN (O-RAN) interfaces in its AirScale portfolio, saying it aims to enable an open ecosystem of innovation and a robust telecom supply chain, while ensuring world-class network performance and security.

Nokia's new O-RAN capabilities, which include open interfaces, build on its existing AirScale software. The company says its O-RAN software delivers the same performance, functionalities and security standards of its current radio products.

An initial set of O-RAN functionalities will become available this year, while the full suite of O-RAN-defined interfaces is expected to be available in 2021.

Nokia notes that it is the only global RAN provider to commit to O-RAN.

Tommi Uitto, President of Mobile Networks at Nokia, said: "Nokia is committed to leading the open mobile future by investing in Open RAN and Cloud RAN solutions with the aim of enabling a robust telecom ecosystem with strong network performance and security. Nokia’s Cloud RAN solution leads the market and is continuing to evolve to a cloud-native architecture. We have ​the scale and capabilities to address the increased customer demand for this technology, underpinned by the world-class network performance and security that only Nokia can deliver."



Nokia moves ahead with 5G Cloud RAN commercialization

Nokia confirmed plans to commercially launch a version of its 5G AirScale Cloud RAN solution that is based on vRAN2.0. The open version  will be commercially available this year with general availability expected in 2021.

Open RAN (O-RAN) splits the base station into Radio Unit (RU), Distributed Unit (DU), Radio Access Point (RAP, a combination of RU and DU), Centralized Unit (CU), and O-RAN compliant interfaces between these elements. Nokia's 5G AirScale Cloud RAN also includes the RAN Intelligent Controller (RIC) concept to take advantage of Artificial Intelligence (AI), Machine Learning (ML) capabilities to optimize the radio and system performance.

Nokia’s first-generation 5G AirScale Cloud RAN based on vRAN1.0, which has a virtualized Central Unit (vCU), has been in commercial operation on a mmWave network in the U.S. since early 2019.

Nokia’s new vRAN2.0 solution introduces a virtualized Distributed Unit (vDU) as well as a Fronthaul Gateway. The result is a fully cloudified and disaggregated 5G base station that provides scalability, low latency, high performance and capacity, as well as several network architecture options, to meet ever-increasing market demands. The solution helps operators to generate revenue from new 5G services as well as to enable flexible end-to-end network slicing, meet IoT requirements and bring the overall benefits of cloud computing to Radio Access Networks (RAN).

The first Nokia 5G AirScale Cloud RAN solution with a vCU in vRAN1.0 configuration was taken into large-scale commercial use in the U.S. in 2019. Since then, Nokia has evolved the solution to vRAN2.0 configuration with a Distributed Unit (DU) running on General Purpose Processor (x86)-based computing with hardware acceleration in Layer 1 (L1).

Nokia moves ahead with 5G Cloud RAN commercialization

Nokia confirmed plans to commercially launch a version of its 5G AirScale Cloud RAN solution that is based on vRAN2.0. The open version  will be commercially available this year with general availability expected in 2021.

Open RAN (O-RAN) splits the base station into Radio Unit (RU), Distributed Unit (DU), Radio Access Point (RAP, a combination of RU and DU), Centralized Unit (CU), and O-RAN compliant interfaces between these elements. Nokia's 5G AirScale Cloud RAN also includes the RAN Intelligent Controller (RIC) concept to take advantage of Artificial Intelligence (AI), Machine Learning (ML) capabilities to optimize the radio and system performance.

Nokia’s first-generation 5G AirScale Cloud RAN based on vRAN1.0, which has a virtualized Central Unit (vCU), has been in commercial operation on a mmWave network in the U.S. since early 2019.

Nokia’s new vRAN2.0 solution introduces a virtualized Distributed Unit (vDU) as well as a Fronthaul Gateway. The result is a fully cloudified and disaggregated 5G base station that provides scalability, low latency, high performance and capacity, as well as several network architecture options, to meet ever-increasing market demands. The solution helps operators to generate revenue from new 5G services as well as to enable flexible end-to-end network slicing, meet IoT requirements and bring the overall benefits of cloud computing to Radio Access Networks (RAN).

The first Nokia 5G AirScale Cloud RAN solution with a vCU in vRAN1.0 configuration was taken into large-scale commercial use in the U.S. in 2019. Since then, Nokia has evolved the solution to vRAN2.0 configuration with a Distributed Unit (DU) running on General Purpose Processor (x86)-based computing with hardware acceleration in Layer 1 (L1).

Tommi Uitto, President of Mobile Networks at Nokia, said: “The next-generation Nokia 5G AirScale Cloud RAN is a true innovation that will transform mobile networks and provide operators with the flexibility they need to meet the customer demands in the evolving 5G era. Its flexible architecture offers speed, coverage, capacity and low latency as well as the opportunity to generate revenues immediately.”

AT&T tests Nokia's RAN Intelligent Controller over commercial 5G

Nokia and AT&T conducted a limited live trial of RAN Intelligent Controller (RIC) over the AT&T commercial 5G mmWave network in New York City.

Last year, AT&T and Nokia announced their collaboration to co-develop the RIC software platform, in alignment with the O-RAN Alliance target architecture. The RIC software is available at the O-RAN Software Community.

For the recent trial, AT&T and Nokia ran a series of external applications, called “xApps,” at the edge of AT&T’s live 5G mmWave network on an Akraino-based Open Cloud Platform. The xApps used in the trial were designed to improve spectrum efficiency, as well as offer geographical and use case-based customization and rapid feature onboarding.

Ultimately, the trial achieved its test goals. Both companies tested the RAN E2 interface and xApp management and control, collected live network data using the Measurement Campaign xApp, the neighbor relation management using Automated Neighbor Relation (ANR) xApp, and tested RAN control via the Admission Control xApp – all with zero interruption to the live commercial network.

Mazin Gilbert, VP of Technology and Innovation at AT&T, said: “This successful trial is a testament to what we can achieve through openness and collaboration. Together with the O-RAN Alliance, AT&T and Nokia will continue to develop and contribute to the E2 interface and the RIC platform to help enable an intelligent and flexible 5G network.”

Michael Clever, Head of Edge Cloud Platforms at Nokia, said: “We are excited about the success achieved by the joint AT&T and Nokia team in proving out the RIC over AT&T's 5G network in such a great city. This represents a major milestone toward the advancement of RAN network intelligence, openness and programmability, with the ultimate goal of improving wireless networks efficiency and end user experience.”

AT&T and Nokia collaborate on open RAN platform

AT&T and Nokia are collaborating on an open software platform under the ORAN Alliance to open up access to 5G radio access networks (RANs). The goal is faster, more flexible service deployments and programmability within a rapidly-evolvable RAN.  The ORAN Alliance aims to enable a multi-vendor open ecosystem of interoperable components for the disaggregated RAN.

AT&T said it is commencing development of a software platform for the RAN Intelligent Controller (RIC), to enable the creation of open source software that is aligned with the O-RAN target architecture. AT&T and Nokia are co-creating the platform code to accelerate the deployment of open source software for the 5G RAN.



Some highlights:

  • The RIC platform will provide a set of functions and interfaces that allow for increased optimizations through policy-driven closed loop automation 
  • The platform will be architected in the form of an extensible real-time microservices framework coupled with a radio information database and key open control plane interfaces for mobility management, spectrum management, load balancing, radio resource control and RAN slicing to name a few.  
  • Implementations of these functions, sourced from multiple vendors, could be mixed and matched on a single network infrastructure. 
The platform will also enable interfaces to third-party applications for enhanced mobility functions such as cross layer optimization and machine learning inferences.

AT&T also plans to increase its engagement in Akraino Edge Stack, a Linux Foundation project focused on building production ready cloud infrastructure for edge deployment in open source. In particular, AT&T has also signed a multiyear co- development agreement with Nokia to further expand Akraino Edge Stack capabilities supporting the needs of the RIC and other edge cloud platform deployments.
