KDDI teams with Nokia on virtualized Cloud RAN PoC

Nokia and KDDI are collaborating on fully cloudified RAN Proof-of-Concept.

The lab-based Proof of Concept (PoC) will use Nokia’s AirScale All-in-Cloud BTS solution and enable KDDI to research how flexible, virtualized radio network technology can support the diversifying network performance requirements in the 5G era.

Nokia’s AirScale All-in-Cloud BTS is a fully cloudified 5G BTS, placing both the real-time and non-real-time baseband in the cloud.The virtualized real-time baseband processing takes place at the far edge of the network to meet extreme latency requirements and provide the ability to scale to meet demand. It is part of Nokia’s broader Nokia AirScale Cloud RAN solution, which offers a flexible mix of local and cloud-based processing.

Nokia said its AirScale All-in-Cloud BTS will be used in the planned PoC to provide a flexible network configuration of a base station virtualization and enable the provision of an optimal 5G network.

KDDI launched commercial 5G services in March 2020. KDDI has been working closely with Nokia on this PoC as well as 5G core standalone network trials.

Ari Kynaslahti, Head of Mobile Networks Product Management at Nokia, commented: “The 5G era will bring with incredible opportunities for businesses and consumers alike but it will place increasing demand on the networks as complexity increases and data traffic explodes. KDDI will be able to use virtualized networks to rapidly respond to its customers’ varied requirements. We look forward to continuing our strong relationship with them in the pursuit of virtualized network best practices and in preparing for a new decade of communication technology.”

KDDI picks Ericsson, Nokia and Samsung for 5G

KDDI named Ericsson, Nokia and Samsung as its primary 5G vendors for next-generation network deployment in Japan.

KDDI expects the first commercial live 5G services to be available from March 2020, with more than 93 percent coverage of 5G base station areas specified by Japan’s telecom regulation body by the end of March 2025.

Ericsson confirmed that it will supply KDDI with Radio Access Network equipment, including products and solutions from the Ericsson Radio System portfolio. The equipment will allow KDDI to roll out commercial 5G services in several parts of Japan on their sub-6GHz and 28GHz bands for 5G New Radio (NR). KDDI’s selection of Ericsson as a 5G vendor follows nearly four years of close collaboration on 5G between the companies.

Nokia also confirmed its selection as a primary partner to upgrade KDDI's 4G network to 5G using its AirScale platform, which supports both 4G and 5G operations. This will allow KDDI to modernize its 4G network and meet the growing consumer and industrial demands for 5G. The contract for 5G radio re-enforces the strong relationship between the two companies, which dates back over two decades.

Nokia is an existing supplier to KDDI across multiple technologies, including radio, fixed networks, mobile core network and multiple software solutions. The 5G network will support KDDI across both cmWave and mmWave 5G frequency bands and can be deployed in both distributed and centralized architectures.

Samsung Networks said it will provide KDDI with its latest 5G network solutions, including various radio base stations supporting mid-band (3.7~3.8GHz and 4.0~4.1GHz) and mmWave (28GHz) spectrum, as well as virtualized RAN.

Radisys and KDDI demo RAN slicing

Radisys and KDDI Research demonstrated RAN slicing involving different traffic streams with different latency requirements on a single Radio Unit (RU) connected to multiple Centralized Units/Distributed Units in a disaggregated network topology.

The demonstration included the creation of a network slice for eMBB (Enhanced Media Broadband) service that spanned a pair of Distributed Units (DU) in an edge cloud site and a Centralized Unit User Plane (CU-UP) in a regional cloud site. This allows an architectural construct of a Network Slice consisting of Intelligent Edge and regional cloud with functionalities to host a 5G service. While eMBB is a high-speed data service, another network slice was created for Ultra Reliable and Low Latency Communication (URLLC) service employing another pair of DUs in the edge cloud.
Key features of the demonstration include:

  • Network slicing to implement workloads for 5G services both edge and regional clouds
  • Showcasing two important 5G services: eMBB and URLLC
  • Creating multiple slices in a single cell

For this demo, Radisys provided an end-to-end configuration consisting of:

  • 5G NR (New Radio) gNodeB in Standalone mode operating in sub-6 GHz frequency range along with RAN controller
  • 5G Core Network including Access and Mobility Management Function (AMF), Session Management Function (SMF) and User Plane Function (UPF)
  • eMBB and URLLC service functionality portioned in edge and regional clouds

“Our deep partnership with KDDI Research is evident with this critical demonstration of advanced network slicing where we connected multiple CUs and DUs to a single RU,” said Arun Bhikshesvaran, CEO, Radisys. “This demo goes beyond the typical single DU and RU binding and really brings to the forefront how mobile operators will manage their networks with intelligent edge deployments and scale into regional clouds to optimize efficiency and operational costs in order to realize the benefits of 5G disaggregation.”

Nokia and KDDI test 4G LTE connected vehicles in Japan

Nokia and KDDI have conducted a series of tests in Japan to assess the use of 4G LTE for low-latency connectivity for vehicles.

For the proof-of-concept trials in Japan, Nokia and KDDI focused on vehicle to network use case and used non-integrated systems in cars interacting with sensors via the Nokia Multi-access Edge Computing (MEC) platform, which enables significantly reduced network latency.

The testing included LTE broadcast, implementing the evolved Multimedia Broadcast Multicast Service standard in two connected car applications, and demonstrating the potential of cellular technology to enable fully automated driving in the future.

Nokia said its evolved Multimedia Broadcast Multicast service (eMBMS) hotspot solution allowed real-time information to be shared with multiple vehicles to enable awareness and road safety. The companies compared the efficiency of using LTE broadcast to the one-to-one communication enabled by LTE unicast, in two connected car applications:


  • Vehicle-to-network-to-vehicle (V2N2V) - in which cars maintained constant contact with the MEC system, sending real-time location, direction and speed data to roadside sensors. In an emergency situation, the driver can alert the application, with information distributed to other vehicles using eMBMS.
  • Network Real-Time Kinematic (network RTK) -trial of LTE to enhance fully automated in-vehicle navigation. It showed how eMBMS could more cost-efficiently use existing geo-location systems to communicate to many vehicles in real-time and ensure accurate navigation.

The trials were conducted by Nokia and KDDI at a rural location on the Japanese island of Hokkaido.
