Beijing News (Reporter Li Yukun) On October 18, 2019 Zhongguancun Forum held a parallel forum "5G empowers the future industry". The reporter learned from the meeting that nearly 80% of operators worldwide will conduct SA networking.
Not long ago, the 5G network SA and NSA model battle was heated, the Ministry of Industry and Information Technology and the official media have rumors, saying that "NSA and SA are true 5G." At the press conference of the Information Office of the State Council on September 20, the Minister of Industry and Information Technology Miao Wei stated that the construction of SA 5G network will start in full next year, and the 5G base stations laid this year are in the form of NSA, which means both NSA and SA 5G networks will coexist for a long time.
The so-called SA and NSA are the abbreviations of Standalone (independent networking) and Non-Standalone (non-independent networking), respectively. Independent networking refers to the creation of a new network, including new base stations, backhaul links, and core networks. Non-independent networking refers to the use of existing 4G infrastructure for 5G network deployment. The 5G carrier based on the NSA architecture only carries user data, and its control signaling is still transmitted through the 4G network.
The state of 5G's NSA and SA technologies has also become the core focus of this forum.
Pang Ce, general manager of GSMA Greater China, Global Mobile Communications Systems Association, said that the three operators in China are very clear that SA is the target network architecture.
"We did a survey of major global operators in two months. 18% of operators believe that SA will be deployed within one year, such as South Korean operators; others believe that they will be deployed within two or three years. Almost 77% of the operators said that they will implement SA networking. Overseas operators have paid more and more attention to SA in the past two months. We are considering how to provide an open platform for operators. 5G guidelines have been issued worldwide to allow the same service level to be enjoyed in different countries and regions, "said Punch.
As an important company in the 5G field, the industry is very concerned about Huawei's choices in technology and industry. Cao Zejun, director of the MKT department of Huawei ’s China strategy, said at the meeting, "Which way does SA and NSA networking need to be combined with the network of the operator Make a decision with future judgments. We know that in the field of communications, the network will evolve towards the future. When it comes to 5G, everyone has an expectation. We firmly believe that the future must be the SA model. We, as a predictor of equipment manufacturers and technology development, I hope to surround our customers and make our due contribution in cost and technology evolution. "
So, if 4G is still needed after 5G, what will happen? Zhang Tongxu, president of the China Mobile Research Institute, said that after the construction of 5G, 4G will continue to progress and develop collaboratively for a long time.
"We propose to build 5G and 4G boutique networks, which can achieve more collaboration. China Mobile will build 5G together with 4G. In terms of hardware and software, 4G and 5G will be integrated and compatible in the future. China Mobile will take SA as the target solution to further promote the rapid development of the SA industry in terms of industry. From the perspective of wireless equipment, various manufacturers have basically launched 5G SA fusion products, and terminal manufacturers have gradually supported SA dual-mode chips. By the end of the year, Corresponding mobile phone products are being launched one after another. China Mobile is building an NSA network by the end of the year, so the core network will share 4G. For the 5G core network, there will be some standard functions at the end of the year, and it is expected to be further commercial next year. Say.
