Oppo just announced that it has successfully conducted voice and video calls solely based on the next-generation 5G network.
Partnering with Ericsson and MediaTek, the VoNR (Voice/Video on New Radio) calls were made on a modified commercial smartphone from Oppo featuring MediaTek’s Dimensity 1000 series SoC using an end-to-end 5G Standalone(SA) network powered by Ericsson Radio System products and solutions.
VoNR is a basic call service that completely relies on the 5G network, specifically with SA architecture which is known as one of the mainstream architectures of future 5G networks. Compared with earlier call services, it provides significantly lower latency, along with greatly improved sound quality and picture quality, resulting in an elevated overall experience for users.
As one of the first mobile phone brands to support VoNR calls under the SA architecture, Oppo aims to ensure that even the early adopters can have a more complete 5G experience.
The successful joint test was carried out under the 5G SA network environment provided by Ericsson at its headquarters in Stockholm, Sweden. After dialing, the two phones connected almost instantly and then seamlessly switched to a high-definition video call with a single keypress.
“We proactively work to accelerate large-scale commercialization of 5G. Our cooperation with Ericsson and MediaTek on VoNR is part of our in-depth collaborations in the 5G era. We aim to become the industry’s ideal partner to deploy 5G around the world and at the same time improve 5G experience for the users,” says Andy Wu, OPPO’s Vice President and President of Software Engineering Business Unit.
In 2019, OPPO joined partners to take the lead in implementing the world’s first video data call based on Dynamic Spectrum Sharing (DSS) technology. As of February 2020, OPPO had filed applications for over 2,900 global patent families and declared more than 1,000 families of 5G Standard Essential Patents to the European Telecommunications Standards Institute (ETSI). In addition, OPPO has submitted more than 3,000 5G standards-related documents to 3GPP, ranking among the top contributors to the international standards organization.
At present, OPPO hosts over 10,000 R&D staff, four research centers, and six research institutes around the world. OPPO founder and CEO Tony Chen pointed out that OPPO will invest 50 billion yuan in R&D in three years to promote research in 5G, artificial intelligence, AR, big data and other fields, as well as building core underlying hardware technologies and software engineering ability. With OPPO’s continuous R&D efforts and broad collaboration with industry partners, the future is closer to reality for its users around the world.
