Huawei recently took the lead in completing the world's first 5g vonr call in the China 5g enhanced technology R & D test organized by the imt-2020 (5g) promotion group, which means that the 5g industrial chain has matured, and domestic operators also have the conditions for trial commercial use.
It is reported that this call is based on the 5g network built by Huawei under the unified organization of imt-2020 (5g) promotion group. Two mate 20 x (5g version) mobile phones (probes) are located in the 5g test outfield of China Academy of information and communication in Beijing and yanqihu campus of Chinese Academy of Sciences in Huairou District. The distance between the two places is more than 60 kilometers. Such a long-distance test will be closer to the real commercial scene.
From the actual test situation, two Mate 20 X (5G version) mobile phones (probes) made multiple voice and video calls, the connection rate was 100%, the voice call was clear, the video call picture was smooth, and this test The success of (probe) is also the world's first VoNR call under the 5G SA network, including voice and video.

Accessibility of basic voice solutions under 5G networks

The success of this Huawei test has allowed domestic operators to further test commercial use of 5G networks. This test is based on the VoNR call under the 5G SA network. This is the basic voice solution under the network. It will carry the basic calls under the 5G network in the future, which is very important for operators (basic provided by telecom operators) Business one).

In addition, this 5G VoNR call uses Huawei's end-to-end 5G commercial products, including 5G wireless access network, core network, bearer network, and 5G chips and terminals. 5G VoNR realizes VoNR service bearer through 5G new air interface, accesses IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) to provide 5G call service, verifies 5G new air interface interoperability and 5G key technologies, and realizes terminal communication under the new air interface standard. Network interconnection.

It should also be noted that this test also announced that Huawei's Kirin 980+Barong 5000 5G terminal solution is ready for commercial use. Huawei Mate 20X 5G mobile phone is equipped with Barong 5000 5G baseband. This baseband is currently the fastest 5G baseband in the industry. It supports SA and NSA network architectures and 2G/3G/4G/5G full-mode network standards. In the Sub-6GHz frequency band, it supports a peak download rate of up to 4.6Gbps; mmWave (millimeters) Wave) supports a peak download rate of 6.5Gbps in the frequency band, and supports up to 7.5Gbps in the 5G NR+LTE dual-connection working mode.

The three major operators' 5G network trial commercialization is getting closer and closer

For the three major operators, Huawei, ZTE, etc. have already completed the three-phase IMT-2020 (5G) test work with the three major operators before. Starting in March this year, the three major operators and mobile phone manufacturers At the same time, the corresponding terminal tests were carried out. The first batch of 5G terminals are Huawei Mate 20 X (5G version), ZTE Tianji AXON 10 (5G version), OPPO Reno (5G version), vivo NEX (5G version), Xiaomi MIX 3 (5G version) and Nubia mini (5G version).

Since January this year, the three major operators have established 5G network trial networks in many cities, and Henan, Anhui, Fujian, Hebei, Jiangxi, Shandong, Jiangsu, Guizhou, Tianjin, Guangxi, Hubei, Liaoning, Beijing, 16 provinces, autonomous regions, and municipalities including Shanghai, Sichuan, and Guangdong have successfully opened up 5G calls. Therefore, from the perspective of the overall environment, the first batch of friendly internal tests for 5G commercial trials have basically met the conditions.

At present, many 5G base stations have been set up in the Fifth Ring Road in Beijing, Shanghai and other cities, which can ensure that some areas can experience the 5G network normally. Of course, if there is no coverage area, the 4G network will be the base. This is the first experience in itself, and the operation Businesses are also increasing their coverage area. Compared with 5G commercial services based on NSA in the United States and South Korea, China Mobile, China Unicom and China Telecom use the (5G+NR) SA-based NSA/SA hybrid network model as their development idea, and this is what Realize the right path to lead 5G network deployment.

On May 17th, operators may start 5G network experience on a small scale

According to the news given by the terminal manufacturers, the early commercial 5G networks of the three major operators were mainly aimed at the four cities of Beijing, Shanghai, Guangzhou and Shenzhen, and they were conducted on a small scale, and only those who wanted to try early were invited. Users come to participate, and if everything is okay, the scope will continue to expand (the cities and user scales for trial commercial use).

As for the time for the trial commercial 5G network, terminal manufacturer sources revealed that the earliest may be the implementation of Telecom Day on May 17th. Of course, this also depends on whether the Ministry of Industry and Information Technology will issue a trial license for 5G network trial commercialization in advance, if the time is delayed. , May have to be postponed until June, but judging from the current efforts of all parties, it is hoped that commercial 5G networks will be tested on the Telecom Day.

In fact, before this, the three major operators have begun to recruit 5G friendly customers, and these recruited users will be the first group to experience the domestic 5G network. With the deepening of testing, the scope of trial commercial use will gradually expand. According to the previous route, operators will officially test commercial 5G networks in the first batch of cities in the third quarter of this year.
