China Mobile and Huawei successfully completed the full-scenario acceptance of the 5G voice test solution

Recently, China Mobile and Huawei have joined hands in Beijing Information Port to complete the full-scene test and acceptance of Vo5G (including VoNR, EPS Fallback, VoNR to VoLTE, etc.) solutions based on 5G independent networking (SA). This is another breakthrough after the completion of the EPS Fallback call test under the 5G SA network in June this year. The successful acceptance of the Vo5G call test indicates that China Mobile’s 5G voice call service technical capabilities in the SA environment have gradually matured. .

VoNR (Voice over New Radio) is a call solution based on pure 5G access, enabling both voice and data services to be carried on the 5G network. In the early stage of 5G SA deployment, due to the small coverage of 5G NR, EPS Fallback became a solution on the road to 5G voice evolution. With the gradual improvement of 5G NR coverage, users will be able to experience higher-definition and high-quality audio and video call services brought by VoNR, and enjoy 5G high-speed data Internet services while making calls.

This test site verified the whole scene of Vo5G, after the EPS Fallback call is quickly reselected back to the 5G network, VoNR audio and video calls, and continuous switching from 5G to 4G to 5G. During the process, several dial tests were conducted, and the success rate was 100%, the call was established quickly, the sound quality was clear, the picture was stable and smooth, and the switching was smooth and lossless. The test experimental network is built based on the target commercial networking architecture and adopts Huawei’s 5G end-to-end commercial solutions, including 5G smart core network, 5G wireless access network, and the first 5G dual-mode terminal Mate 20X smart phone.

  

The voice solution is one of the important foundations of 5G SA. China Mobile and Huawei successfully completed this systematic 5G voice test, and the experimental network is highly consistent with the target commercial network, marking China Mobile’s 5G commercial maturity. Stride.
