Vonr SMS has been opened.

The core application of "Ultra-clear Video" in 5G new call is an integrated solution of audio and video services based on VoNR(Voice over New Radio) technology.

It is understood that in the initial stage of the operation of the 5G network, because the 5G base station has not been fully covered, the mobile phone still uses 4G Volte technology. When the user makes a call, the network often falls back to 4G. However, with the continuous coverage of the 5G network and the continuous coverage of the 5G signals, it has become the consensus of major operators that the VoNR scheme is adopted for 5G voice. Because VoNR directly carries IMS voice services end to end through 5GS, the voice call setup time is shorter, the voice quality is better, and users can enjoy the carefree 5G network speed while making voice calls, and the user experience is greatly improved.

It is reported that as early as March 2002 1 year, the terminal strategy released by China Mobile revealed that "from March 2002 1 year to June1year, terminals with a price of 4,000 yuan and above must choose 700MHz, and from June1year, new terminals must choose to support 700MHz. At that time, Jian Qin, deputy general manager of China Mobile, said that in order to integrate VoNR voice into 5G, it was hoped that starting from 20211kloc-0/,the new terminal must support VoNR applications, and it was not allowed to set the VoNR switch in the user interface, so that the support area could turn on VoNR accurately.

In the first half of 200212002, Huawei also announced that it and China Unicom were the first to upgrade the VoNR voice scheme for 5G commercial networks in Shenzhen, and completed the VoNR verification of the first 5G commercial network. In the 20021World 5G Conference, China Mobile took the lead, and Huawei and other companies 10 jointly set up a 5G VoNR+ (new voice) working group to promote the application of VoNR technology.

In addition to mobile, an insider broke the news at the beginning of this year: Unicom has tested the VoNR function in some areas, which can maintain high-speed and low-latency 5G network connection while making high-definition voice calls. However, this function has not been fully commercialized, and it is only tested in some regions and some models.

Now that the new 5G call has officially landed, what's the use of the new 5G call? Take the 5G ultra-clear video call as an example. Compared with the audio and video calls of social software, the 5G ultra-clear video call carries voice, video and data services based on the 5G SA network architecture, and is not affected by the network speed and network signals. Compared with Internet video calling, it has three advantages: high definition, no jam, no need to add friends and no traffic occupation. Moreover, the resolution of 5G ultra-clear video call can reach 720p, which further improves the stability of the call, even if other calls come in during the call. Moreover, in fact, the operation process of 5G ultra-clear video call is very similar to that of ordinary voice call, and you can dial by using the traditional mobile phone dialing interface without downloading software, logging in applets or adding friends.

In addition to the 5G ultra-clear video call, the main functions of the new 5G call include 5G video customer service, AI speech recognition (real-time translation between Chinese and English, technology to help the elderly), screen sharing, remote collaboration and talking with virtual digital homo sapiens. The customer service function of 5G video has been opened to mobile customers in some cities in 25 provinces, covering many mobile business scenarios such as basic business investigation, highly sensitive business authorization and remote operation guidance.

Regarding how to open new products of 5G calling, the mobile side responded: In order to facilitate users to experience 5G ultra-clear video service, Mobile will actively open the "two-party ultra-clear video calling function" for customers whose terminals support VoNR function, and users can also turn it off freely. For users with inappropriate terminals, users can open services through all channels such as business hall, 10086 hotline and SMS office after changing terminals.

It is reported that the 5G terminal listed in June 2020 or later can support the ultra-clear video calling function of VoNR voice and video after software upgrade. At present, mainstream brands such as Huawei, OPPO, Xiaomi, Glory, vivo, realme, Samsung and China Mobile NZONE have started to gradually push new versions, and Apple mobile phone users still need to wait for this feature.
