On June 15th, a new generation of mobile communications test and verification national engineering laboratories, a new generation of mobile communications technology application national engineering laboratories and a new generation of mobile communications wireless network and chip technology national engineering laboratories jointly held the council meeting and technical committee meeting . This is also the first time that the 3 units that are the main promoters of domestic 5G jointly held the National Engineering Laboratory Conference. The meeting believed that the release of the first standard version of the 5G independent network marked the establishment of 5G technical standards and the acceleration of the industrialization process. The 5G industry will be fully launched, and testing, R&D and testing will be carried out in all directions. The three laboratories will continue to strengthen industrial cooperation and provide support for the scale of commercial use of 5G in 2020.

According to the 3GPP plan, the 5G standard is divided into two types: independent networking and non-independent networking. Among them, the non-independent networking, because its 5G air interface carrier only carries user data, system-level service control still relies on the 4G network, and the new 4G network is added to the existing 4G network for capacity expansion. Because it is still dependent on the core network and control plane of the 4G system, the non-independent networking architecture cannot fully exploit the technical characteristics of the low latency of the 5G system, nor can it achieve flexible support for diversified service requirements through features such as network slicing and mobile edge computing. .

In response, Wang Zhiqin, deputy director of the China Academy of Information and Communication Technology, explained to the Economic Daily reporter that the non-independent networking method is to attach 5G wireless technology to 4G networks to conduct business, and therefore it is subject to certain restrictions. Its application scenario is mainly mobile internet. . At present, from a global point of view, operators in the United States and South Korea mainly consider the application of non-independent networking in the early stages, so that the deployment is faster.

3GPP defines three scenarios for 5G, namely, enhanced mobile broadband, low latency, high reliability, and massive connections. Non-independent networking can only meet some of the scenarios in mobile broadband enhancement, and it can not meet the two scenarios of low latency, high reliability, and large-scale large-scale connectivity. Applications such as the Internet of Things (Vehicle) and the Internet of Things (IoT) need an independent networking mode.

Different from 4G and other generations of mobile communications, 5G can provide very clear and personalized communication services according to different demands of various services. The 5G independent networking can not only reduce the dependence on the existing 4G network, but also better support various services such as 5G large bandwidth, low delay and large connections, and can provide customized services according to the scenario to meet the needs of various users. Business needs, greatly enhance the customer experience.

"The development of China's 5G industry has always taken into account both independent networking and non-independent networking. Domestic operators are even more inclined to establish an independent network at an early stage. Because of this, the introduction of 5G independent networking standards is of far-reaching significance for China. "Wang Zhiqin said.

"Undoubtedly, independent networking is our goal." Zhang Tongxiu, dean of the China Mobile Communications Research Institute, told reporters that since only independent networking can truly meet the three major scenarios defined by 5G, it is the 5G in the true sense. The initial independent networking may require more investment, but in the long run, the non-independent networking needs to undergo two transformations, and the total investment is not small.

The industry generally believes that the introduction of 5G independent networking standards means that the pace of commercial use is accelerating. Zhang Tongsu said that the introduction of 5G independent networking standards has a great impact on operators and even the entire industry. Because the standard is the basic framework and requirements, with the standard, the development of all aspects of the industry chain has been the basis for further landing, it will also promote operators to speed up the construction of the network. At present, China Mobile has already advanced 5G scale trials in 5 cities and 1,000 5G base stations will be built by the end of next year.

According to Zhang Yong, president of the China Unicom Network Technology Research Institute, China Unicom will conduct 600 experimental network constructions in 16 cities. The next step will be in industry, sports,videoTen industries, such as smart cities, carry out cooperative experiments to enrich 5G applications. Chen Shanzhi, vice president of Datang Telecom Group and director of the National Engineering Laboratory, said that 100 base station continuous coverage trials have been started, and testing will be completed in the first half of next year and the second half of the year will enter the pre-commercial phase.

According to the 5G standardization process determined by 3GPP, by 2020, 5G will be fully commercialized. "The commercial use of 5G depends on many factors. At present, the introduction of 5G independent networking standards has the greatest impact on the manufacturing industry, because equipment manufacturers can finally do related equipment," Wang Zhiqin said. Chen Shanzhi also stated that the 5G equipment that Datang Telecom mainly produces are base stations, test instruments and chips. Among them, the base station has long been in the direction of independent networking.Development, and the chip has been waiting for the standard to be produced.

“5G, the biggest challenge for operators is to improve their operation and maintenance capabilities, how to transform them into a software company and to operate and maintain a cloud-based network. For our manufacturers, the challenge is how to optimize products and support operators to improve Operation and maintenance capabilities, said Chen Shanzhi.
