China Telecom develops 5G slicing technology to help the industry's digital transformation

On the road of 5G popularization, China Telecom has spared no effort. Recently, China Telecom has made a huge breakthrough in 5G slicing. According to C114 Communication Network, China Telecom and Huawei recently jointly released the research results of the "5G Terminal Application Slicing Acceleration Project". This project is a strategic cooperation project between China Telecom and Huawei. It relies on China Telecom’s self-developed slicing acceleration platform and terminal self-developed SDK. And Tianyi No. 1 2021 will jointly realize terminal application slicing acceleration, and provide "one-click acceleration" experience verification for Tianyi Cloud mobile phones and Tianyi Cloud computers. This is the first time in the industry to realize terminal application-level slicing in the 2C market and complete the end-to-end live network. verify. In fact, in recent years, the three major operators have been making efforts to slice 5G networks. The commercial use of 5G SA makes it possible to apply network slicing technology, and the 5G network slicing solution will also release the potential of 5G in multiple scenarios, bringing personalized and customized network services

1. China Telecom continues to develop 5G network slicing applications

China Telecom's 5G slicing has obvious advantages. According to Wang Qingyang, director of the Institute of Mobile Communications, China Telecom Research Institute, China Telecom has independently developed general capabilities for 5G slice orchestration, which can realize network slice lifecycle management, sub-slice management, and 5GC network configuration services. At present, Shenzhen's first police slicing private network based on the end-to-end 5G SA network has been opened, the 5G SA slicing service of Chongqing Smart Expo has been opened, and 5G directed traffic services have been supported. He also stated that China Telecom has implemented pilot 5G dedicated line services in Guangdong, Beijing, Jiangsu, Zhejiang, and Hubei, and signed contracts with Beijing (National Museum, Army, Beijing TV, Tsinghua University, Xidan Complex, etc.), Guangzhou (Shenzhen Public Security, Tianhe Bus) Etc.), Jiangsu (Jiangyin Port, Zhenjiang Port, etc.), Zhejiang (Qinshan Nuclear Power Plant, Hangzhou Boiler Group, etc.), etc. The 5G slicing acceleration platform and Tianyi No. 1 2021 terminal have been verified through the whole process experience in Beijing and Guangdong to lay a solid foundation for operators to provide higher-quality 5G 2B 2C slicing acceleration services, which will give birth to a richer 5G 2B 2C Application scenarios and business models promote the ecological development of the industry.

2.5G slicing accelerates the landing of 5G vertical industry applications

Network slicing, as a key technology in 5G systems, has received increasing attention, and the three major operators have explored the application of 5G network slicing. China Telecom has already implemented many industry applications for 5G network slicing. For example, recently, the 5G Internet of Vehicles project jointly created by China Telecom and Dongfeng Lantu Automobile, through 5G network slicing technology, provides car owners with data security isolation and privacy protection; China Telecom and Sichuan Yongxiang Photovoltaic Technology Co., Ltd. passed The sinking and slicing technologies of UPF and MEC have built an exclusive 5G network for the factory to achieve high-density and mass connections while meeting the confidentiality requirements of the factory; China Telecom uses deep integration of network slicing and public security applications to achieve police business and Hard isolation between public services to ensure that the delay of police services is stabilized within 20 milliseconds, and to create a new benchmark for 5G smart police services in Shenzhen. China Mobile and China Unicom are also working on 5G network slicing applications. China Mobile currently opens the country’s first 5G SA commercial slice for the medical industry. Relying on 5G, edge computing, network slices, etc., it serves as the Internet Service Experience Center of the Shunde Hospital affiliated to Jinan University, the ambulance emergency center, the AR intelligent surgery platform, and the telemedicine center. Carrying out wisdom empowerment; China Unicom provided Gree with an end-to-end 5G SA slice private network, and the delay from 5G terminals in the Gree park to the corporate intranet was reduced from the original 20ms to 9ms.

3. Operators leverage 5G slicing to transform to diversification

Industry experts pointed out that network slicing technology has universal applicability, can be applied to all walks of life, and can help the 5G business model to diversify. In order to promote diversified transformation, the three major operators have launched customized slicing services for private networks. China Mobile customizes three types of networking modes: "Private, Exclusive, and Exclusive" for customers on demand. China Telecom is divided into three types of service models: "Zhiyuan, Neighbor, and Ruyi" based on typical application scenarios. China Unicom's 5G private network is divided into three types: There are three deployment methods: virtual private network, hybrid private network, and independent private network. There is no doubt that network slicing is a key technology for operators to provide differentiated services in the industry. It is good for the digital transformation of the industry and is also a new export for the future development of the entire information and communication industry.
