On April 12, China Unicom recently released the "2021 Terminal Evaluation Report". The content shows that China Unicom's 5G VoNR technology has made great progress, and the VoNR connection rate under the Unicom network has reached 100%, and the delay has been significantly improved compared with last year, and it has already met the commercial conditions. It is estimated that Unicom's 5G VoNR will soon be commercially available on a large scale, and the era of high-definition video calls has come.
As early as February, some netizens broke the news that Unicom began to test the VoNR function in some areas, and only a few models could use it at that time. After turning on VoNR, even if you are calling, your phone can still maintain a high-speed 5G network connection, the game will not suddenly drop, and improve the user's call experience.
5G VoNR refers to the end-to-end voice service carried by 5G NR, 5G Core and IMS, which can bring users a better call experience. The telephone connection delay is lower, and theoretically you can connect the moment you dial, and you no longer need to make a call "beep beep" for most of the day.
In addition, the sound quality of voice calls is also higher, 5G VoNR supports a new EVS codec, more advanced than 4G VoLTE, the call sound quality is clearer, and there is almost no noise or disconnection of the unclear hearing. It also supports 720P resolution HD video calls, compared with VoLTE's 480P resolution to improve a level, the sound and picture quality have been greatly improved, video calls are clearer and smoother.
Not only Unicom, but also mobile and telecom are also conducting 5G VoNR function tests in many regions, and it should not be too long before it is officially commercialized. Although 5G technology has been commercially available for more than two years, and 5G mobile phones on the market are almost fully popularized, there are really not many users who actually use 5G packages.
Statistics from the three major operators last year showed that China Mobile's 5G package subscribers were 386 million, and Telecom and China Unicom were 188 million and 155 million, respectively. Now many people have two or even more mobile phone numbers, to be honest, 5G package users are really not many.
Many people buy 5G mobile phones when 4G is used, and even directly turn off the 5G switch, because 5G does not have too obvious improvement compared to 4G. However, the situation may change after 5G VoNR comes out, it and 5G SMS must be used after you open a 5G package, and if you want to use HD video calling, you have to upgrade the plan. Therefore, the three major operators are actively promoting the commercialization of this technology, which will greatly help to accelerate the conversion of 5G package users.
