On November 7, Li Zhengmao, general Manager of China Telecom, announced that China Telecom would take the lead among global operators in large-scale commercial 5G SA network, support THREE application scenarios of eMBB, URLLC and mMTC, and build new infrastructure core facilities.
SA (independent networking) and NSA (non-independent networking) are two globally available 5G networking modes. Comparatively, 5G SA can effectively support all application scenarios of 5G and provide diversified, differentiated and personalized services and services. Therefore, this is also the evolution direction and target architecture of 5G network. 5G NSA USES 4G core network, and some performance still fails to meet the real requirements of 5G. In the early stage, the use of NSA networking can speed up the construction progress and reduce the difficulty of deployment. In the later stage, it can be upgraded to SA networking based on the existing NSA.
In early February, China telecom, announced that it took the lead in the industry to complete the 5 g SA core network commercial equipment the whole system performance verification, and 5 g end-to-end system function verification and send test is completed to different vendors, pushing more than 5 g SA equipment in function, performance, and factory has the capability of commercial network, which laid a foundation for the scale of the 5 g SA deployment.
It is reported that China Telecom will commercial 5G SA in 300+ urban scale. Currently, 5G SA has been supported by 30+ mobile phones. By the end of the year, it will be supported by 100+ mobile phones and a number of 5G industry terminals. According to the disclosed data, China Telecom has built more than 320,000 5G base stations nationwide.
Commercial use of 5G SA network has been one of the focuses of contention among the three major carriers. In addition to China Telecom, China Mobile and China Unicom are also pushing forward the construction and commercial use of 5G SA network. Recently, at the "5G Application Innovation Summit Forum", Duan Xiaodong, vice President of China Mobile Research Institute, pointed out that after more than a year's promotion, 5G has presented three changes: first, from independent networking to independent networking, 5G is becoming more and more mature; Secondly, from basic to expansion, 5G capacity is becoming more and more perfect. Third, from technological innovation to application innovation, 5G applications are becoming more and more abundant.
In terms of network construction, China Mobile has built the world's largest 5G boutique network, covering 340 cities nationwide. By the end of this year, China Mobile will have built more than 350,000 5G base stations, exceeding the 300,000-station 5G construction plan. So far, China Mobile has had more than 98 million 5G plan users. At the same time, China Mobile has introduced 5G independent networking, and a large number of base stations are gradually and orderly cutting into SA mode, providing new architecture design, new technology foundation and new service capability. By the end of this year, China Mobile will have completed the construction of the world's largest stand-alone 5G network.
Zhejiang Mobile is China Mobile's first provincial-level operator with commercial capabilities for 5G SA. In September, Zhejiang Mobile officially announced that it was the first to launch 5G SA scale application. As early as 2019, Zhejiang Mobile launched the world's first autonomous and controllable 5G SA cloud network, taking the lead in realizing the large-scale commercial use of 5G SA in Hangzhou, Ningbo, Wenzhou and Jiaxing.
In October, Ma Kui, general manager of China Mobile Sichuan, announced that Sichuan Mobile 5G Independent Networking (SA) was officially commercialized. With the official entry of 5G SA network in Jiujiang, Fuzhou and Pingxiang of Jiangxi province, China Mobile Jiangxi has also achieved the target of commercial use of 5G SA network in the whole province.
In June, The Beijing branch of China Unicom announced the launch of 5G SA. China Telecom and China Unicom have completed the world's largest 5G sharing and sharing network, and the two sides will add 58,000 5G base stations by the end of the year, according to Zhang Xin, general manager of China Telecom group's 5G Sharing and Co-construction Working Group.
China Unicom did not respond to an interview with Beijing Business Daily about when it will officially commercialize 5G SA.
Statistics from the Ministry of Industry and Information Technology show that the number of 5G terminal connections in China has exceeded 160 million. So far, 207 5G terminals have been licensed, including 180 5G phones from 34 brands, accounting for nearly 80 percent of new phones launched in the last two months.
