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).

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.

Rakuten tests O-RAN 5G Massive MIMO with Altiostar and NEC

Altiostar confirmed that its O-RAN Alliance-compliant multi-vendor massive-multi-input, multi-output (mMIMO) 5G solution is in now in testing with with NEC Corporation and Rakuten Mobile.

Specifically, Altiostar is integrating the O-RAN distributed unit (O-DU) functionality of its virtual radio access network (vRAN) software with NEC's O-RAN Radio Unit (O-RU) using fully compliant control, user, synchronization and management (C/U/S/M) plane protocols based on O-RAN Alliance guidelines. The 5G layer is built using container network functions (CNF) that leverage Rakuten Mobile's cloud infrastructure platform that is part of its 4G network build out.

As part of management-plane integration, Altiostar is following a hierarchical model that allows the O-DU software to manage the NEC O-RU, including providing software upgrades, RU configuration, fault management and performance monitoring. This interoperability is being performed for 5G new radio (NR) sub-6 GHz massive MIMO O-RU and meets all the 3GPP downlink/uplink (DL/UL) requirements.

"Open RAN as a concept is one that the whole industry is now actively pursuing as a means to introduce supply chain diversity into mobile networks globally," said Ashraf Dahod, CEO of Altiostar Networks. "Altiostar is leading the industry with this network transformation by ensuring interoperability, integration and most importantly extensive testing to ensure that we have a commercial, carrier-grade solution for both 4G and 5G while keeping the principles of Open RAN in place."

"Rakuten Mobile is a big supporter of O-RAN principles and has seen the benefit of supply chain diversity in our own network," said Tareq Amin, Representative Director, Executive Vice President and Chief Technology Officer of Rakuten Mobile. "By combining the spectral efficiency of massive MIMO along with an advanced cloud-based RAN, we are leveraging and introducing advanced innovative technology from both NEC and Altiostar, who are specialists in these respective fields."

Altiostar's container-based 5G solution splits the baseband into the CU and DUs using micro-services to disaggregate these RAN workloads at a deep level. The DU provided by Altiostar is interoperable with, and uses, O-RAN compliant interfaces to work with third-party O-RUs. These workloads can be deployed flexibly to support different quality of service (QoS) and other requirements of the 5G network slice.

The Altiostar containerized architecture also intrinsically introduces Control and User Plane Separation (CUPS). Thus, containers that support IoT can be sized differently when compared to other workloads, such as enhanced Mobile Broadband (eMBB) applications. Alternatively for ultra-reliable low latency communications (UrLLC) applications like V2x or augmented reality, the operator can dynamically deploy the user plane containers at far-edge locations.

NEC has designed its 5G Radio Unit (RU) as an active antenna array system (AAS) that consists of an RF front end and a massive-element antenna in order to minimize the system footprint and provide high-efficiency.

NEC's AAS utilizes a fully digitized antenna beam control technology that improves the precision of beam forming. While transmitting beams to the target mobile handsets, it is capable of forming beams that counteract interfering signals using multi-path. It can also form beams that improve communication quality by efficiently combining the multi-path of its own signals with the direct waves.

The features of NEC's AAS enable concurrent communication with several handsets, even though they are close to each other, while maintaining high communication quality. In the trials, NEC proved that use of the AAS can result in improved capacity and quality of communication between a base station and handsets, while confirming that spectral efficiency was reliably maintained at a level roughly eight times higher than that achieved by LTE in indoor environments.

DOCOMO commits to multivendor O-RAN for 4G/5G

NTT DOCOMO has commenced deployment of a 4G/5G multivendor radio access network conforming to O-RAN specifications.

Working in collaboration with Fujitsu, NEC, and Nokia, DOCOMO has demonstrated multi-vendor interoperability across a variety of 4G and 5G base station equipment compatible with O-RAN. The O-RAN standards include fronthaul specifications and X2 profile specifications.



O-RAN fronthaul specifications are used to establish the connections between centralized units hosting baseband processing and remote units hosting radio processing in 5G remote-installed base stations. O-RAN fronthaul interface specifications provide a foundation for interoperability between centralized units and remote units of 5G remote-installed base stations manufactured by diverse partners.

The O-RAN X2 profile specifications provide a foundation for interoperability between 4G base stations and 5G base stations manufactured by diverse partners in 5G non-standalone (5G NSA) networks by taking 3GPP X2 interface specifications and specifying detailed standards for their usage. 5G NSA networks connect devices using both 4G and 5G technologies.

DOCOMO believes this represents the world's first realization of this level of multi-vendor interoperability in 4G and 5G base station equipment conforming to O-RAN specifications. The ability to deploy and interconnect base station equipment from different vendors will make it possible to select the equipment most suitable for deployment in any given environment, such as base stations offering broad coverage in rural areas or small base stations that can be deployed in urban areas where space is limited.

DOCOMO will deploy the equipment in the pre-commercial 5G service it plans to launch on September 20, 2019 in Japan.
