Jiwei Network News Recently, Deutsche Telekom announced that it has successfully implemented 5G VoNR calls with several partners such as Xiaomi. This is also the world‘s first 5G VoNR call in an end-to-end multi-vendor environment. It is worth mentioning that Xiaomi is the only Chinese brand on the list this time.
It is understood that the test used Samsung S21 5G and Xiaomi 11 Lite 5G, as well as a variety of mobile phone devices on Qualcomm Snapdragon 888 and 780G platforms. Xiaomi is the only Chinese mobile phone manufacturer participating in the test.
Compared with 4G VoLte, 5G VoNR has higher call quality and lower latency. It can keep 5G data online while enjoying high-definition calls, which can further enhance the user experience.
This technology does not need to use 4G and other networks for voice calls, and directly uses 5G SA networks for VoNR protocol calls. VoNR in the 5G SA mode is a call solution based on pure 5G access. Both voice and data services are carried by the 5G network and do not rely on 4G. It is the target voice solution for the mature development of 5G.
It is worth noting that China Mobile pointed out in its white paper in March this year that from October 1, 2021, new 5G terminals purchased by China Mobile must support VoNR. (Proofreading/Candy)Return to Sohu to see more
