According to the information, China Unicom and Huawei completed the first large-scale upgrade of the 5G commercial VoNR voice solution in Shenzhen. This is the first VoNR end-network compatibility and mobile performance based on the existing network environment of over 100 stations connected SA. verification.
This test is based on the 5G commercial network of Shenzhen Unicom, with a site scale of over 100 sites, the joint terminal chip end-to-end complete 5G basic voice, video calls, 4G/5G voice switching, and other basic function tests.
The first 5G-based contiguous coverage of the VoNR mobile performance test under the scene fully verified the commercial performance of VoNR.
VoNR, as the ultimate 5G voice solution, no longer relies on 4G calls, but directly establishes voice bearers on the 5G network, achieving “zero fallback” for 5G calls. VoNR can provide a higher-quality call experience than 2/3/4G voice, and users can enjoy a faster 5G network speed while performing voice services.
