According to the news on February 23, according to the netizens of the Communication People's Home Forum, Unicom has tested the VoNR function in some areas, and can maintain a high-speed and low-latency 5G network connection while making high-definition voice calls. However, this function has not yet been fully commercialized, and it is only tested in some regions and some models.
It is understood that China Mobile and China Telecom are also recently conducting VoNR function tests, and Xiao Lei mentioned a few days ago that rural Fujian has covered N41 VoNR functions. It can be found that the three major operators have been competing on this new track, and have accelerated the deployment of VoNR, striving to reach the national commercial market.
Many small partners may be curious about what VoNR is and why the three major operators are so actively promoting this function. VoNR can also be called "5G phone", which is essentially the same as VoLTE in the 4G era, 6 features are voice calls with the help of 5G networks, and there is no disconnection when making calls. The biggest change in VoNR compared to VoLTE is that the network speed is faster and the call quality is clearer.
Why VoNR is so important is starting from the development of mobile networks. The earliest 1G/2G network is actually a network built to "transmit telephone voice", and its role is to make calls. Later 3G networks were too fast-seeking, resulting in many network bands not supporting voice channels and relying only on 2G networks to make calls. Therefore, every time you call, the network must be disconnected, and the call quality is not good, often inaudible or suddenly broken.
In the 4G era, the original 4G network has only increased the speed, and the call still has to rely on the 2G network. Therefore, when 4G was used at the earliest, the phone was disconnected, and the call quality was still not bad. Later, the mobile communication industry finally developed a VoLTE technology, that is, with the help of 4G networks to transmit telephone voice. Only then did I really say goodbye to the situation of disconnecting from the Internet on the phone.
However, due to the late appearance of VoLTE, many mobile phones in the early days did not support this function, and they still had to use 2G networks, which caused a huge obstacle to 2G network withdrawal. Nowadays, the three major operators are trying to promote 5G packages, and VoNR is a feature that must be upgraded to 5G packages. Once VoNR is fully commercialized, it will be of great help to promote 5G packages.
In addition, the failure of the layout of the previous 3G/4G era has also brought certain lessons to operators. So now will be in the early days of the rise of 5G networks, the rapid promotion of VoNR functions. It is expected that soon, everyone will be able to use VoNR, and the Internet experience will be comprehensively improved.
