Rakuten Cellular has established its first partnership with one other service supplier to share its learnings from constructing its greenfield wi-fi community. Right this moment, Rakuten Cellular signed a Memorandum of Understanding (MoU) to work with Telefónica on open radio entry community (RAN), operation help programs (OSS) and 5G core applied sciences.
The companions will conduct trials of open RAN architectures, together with CUs, DUs, RRUs, and different mandatory community gear and software program parts. They’ll additionally collectively develop proposals for the function of the synthetic intelligence within the RAN.
In an e-mail to FierceWireless, a Telefónica spokesperson stated, “So far as normal open RAN initiatives, we’ll deploy pilots in our core markets of Brazil, Germany, Spain and the UK between this 12 months and the start of subsequent 12 months. Our goal in these pilots is creating a brand new RAN vendor that includes a selected consortium with higher possibilities to ship open RAN efficiently. To take action, we’re working to develop the know-how via our strategic collaboration with Altiostar, Gigatera Communications, Intel, Supermicro and Xilinx.”
Telefónica plans to deploy open RAN in three phases:
- Section 0 / 2020-2021: Pilots
- Section 1 / 2021-2022: Preliminary deployments
- Section 2 / 2022: Large deployments in Spain, Brazil, Germany and UK
“The target is having open RAN in 50% of the community deployed between 2022-2025,” stated the spokesperson.
Enrique Blanco, CTO and chief info officer at Telefónica, stated in an announcement immediately: “Telefónica strongly believes that networks are evolving towards end-to-end virtualization via an open structure, and open RAN is a key piece of the entire image. Telefonica and Rakuten Cellular have signed this MoU to work towards evaluating and demonstrating the aptitude and feasibility of open RAN architectures and make them a actuality.”
With Rakuten Cellular, Telefónica can even collaborate on 4G and 5G core know-how. At the moment, Rakuten is utilizing Nokia know-how for its 4G core, but it surely’s working with Japan’s NEC for its 5G standalone (SA) core.
The 5G SA core from NEC relies on containers. And never solely will Rakuten Cellular use this core in its personal community, however Rakuten and NEC plan to supply it as a product to different operators, so it’s attainable that Telefónica may very well be a primary buyer for this 5G core product.
And eventually, Telefónica and Rakuten Cellular will refine OSS know-how that’s presently utilized by Rakuten Cellular in Japan. Rakuten Cellular’s OSS relies on know-how from the startup Innoeye, an organization that Rakuten bought in Might.
Earlier this 12 months, Rakuten Cellular CTO Tareq Amin advised FierceWireless that Rakuten was utterly revamping telecom OSS. “I’ve by no means been a giant fan of how the OSS layer has been orchestrated for the previous 20 years,” he stated. “If you’re in any telco immediately, you’ll uncover 100-plus bins that do various things. The OSS/BSS platform we have now constructed converges the whole lot, converges these 100 separate bins with synthetic intelligence and machine studying.”
Right this moment, Amin stated in an announcement that he envisions the partnership with Telefónica to additionally “co-explore” additional growth across the Rakuten Communications Platform (RCP).
RCP is comprised of all of the learnings Rakuten Cellular compiled whereas it was constructing its greenfield 4G community in Japan. Rakuten has arrange international headquarters in the US and in Singapore to advertise its RCP.
Requested if Telefónica deliberate to make use of the RCP in its personal community deployments, a Telefónica spokesperson stated, “The MoU doesn’t suggest initially using Rakuten’s Communications Platform.”
