No more relying on 4G calls! Huawei has completed the first VONR verification of its 5G scale commercial network
In the 5G era, voice services are still one of the essential basic services for operators.
In May 2019, the world's first VONR voice and video calls under the 5G SA network will be completed; In the first half of 2020, we have completed the VONR first call under the core network of the existing network of different manufacturers in Shenzhen, Guangzhou, Chengdu, Hangzhou, Shanghai, Shijiazhuang and other cities.
As the ultimate voice solution of 5G, VONR no longer relies on 4G phone calls, but directly establishes voice bearer in 5G network, and realizes "zero drop" in 5G phone calls. Not only does VONR offer a better call quality than 2/3/4G voice, but users can also enjoy faster 5G Internet speeds while doing voice services.
