KT, NTT DOCOMO, Fujitsu, SOLiD, Keysight and ETRI Successfully Conducted Multi-vendor Interoperability Tests Using Virtualized Open RAN and Demonstrated at Global O-RAN PlugFest Spring 2023

June 15, 2023 — KT Company, NTT DOCOMO, INC., Fujitsu Restricted, SOLiD, Inc., Keysight Applied sciences, and Electronics and Telecommunications Analysis Institute (ETRI) have efficiently carried out an interoperability check utilizing virtualized Open RAN on the 5G Testbed Heart, operated by the Ministry of Science and ICT and the Nationwide Data Society Company (NIA), which is chargeable for increasing South Korea’s Open RAN ecosystem, within the metropolis of Pangyo in June 2023.

Constructing on the profitable outcomes, the 5 firms and organizations participated within the “World O-RAN PlugFest Spring 2023” occasion hosted by the O-RAN Alliance. O-RAN PlugFest is a worldwide demonstration occasion the place the openness and interoperability of base station tools from completely different producers are examined, and the check outcomes are shared to increase the Open RAN ecosystem.

Through the occasion, the 5 firms and group collaborated to construct a virtualized Open RAN base station with multi-vendors and introduced numerous demonstration outcomes aligned with the O-RAN Alliance specs, equivalent to checks for traditional conformance, multi-vendor interoperability and end-to-end efficiency.

The demonstration featured the primary virtualized 5G base station composed of a number of distributors in South Korea. The virtualized Distributed Unit (DU) comprised a basic server geared up with a {hardware} accelerator from NVIDIA and Fujitsu software program deployed on the virtualization platform from Wind River. The virtualization of wi-fi community tools is taken into account a vital expertise for the longer term evolution of 6G networks.

The demonstration check was carried out in cooperation with international Open RAN expertise firms on the Pangyo 5G Testbed Heart. KT, the host of the occasion, was in command of organising the virtualized Open RAN base station and testing end-to-end efficiency. DOCOMO and Fujitsu have been chargeable for testing interoperability utilizing virtualized Open RAN Central unit (CU) and DU tools. SOLiD and ETRI dealt with testing interoperability and customary conformance utilizing Open RAN Radio Unit (RU) tools, respectively. Keysight was in command of analysis monitoring and check automation options.

Previous to PlugFest, KT, DOCOMO, Fujitsu and SOLiD efficiently carried out a multi-vendor interoperability check utilizing virtualized Open RAN CU/DU and Open RAN RU. The virtualized Open RAN CU and DU have been developed as a part of the OREXTM*1 mission promoted by DOCOMO and different companions together with Fujitsu.

KT will actively contribute to increasing the home Open RAN ecosystem by collaborating within the Open RAN Trade Alliance (ORIA*2), which is public-private cooperative group in South Korea.

Going ahead, KT, DOCOMO, Fujitsu and SOLiD plan to increase their collaboration in the direction of the 5G Open RAN ecosystem to advertise the introduction of a virtualized Open RAN and RAN Clever Controller (RIC) to optimize administration of radio assets and automatic operations.
