China Telecom, State Grid and Huawei jointly completed the world’s first power slice test based on 5G SA network

Recently, China Telecom Jiangsu Corporation, State Grid Nanjing Power Supply Company and Huawei successfully completed the industry’s first power slice test based on real grid environment in Nanjing, which is also the world’s first based on Power slice testing of the latest 3GPP standard 5G SA network. The success of this test marks the beginning of a new phase in 5G’s vertical vertical industry application.

Based on 5G SA power slicing, this test can fully utilize the millisecond low latency capability of 5G network, combined with the SLA guarantee of network slicing, and enhance the two-way interaction between power grid and power users, effectively improving the overload of the grid load. The precise management capability of the small particle load unit at the end of the grid will minimize the economic and social impacts caused by power outages.

Huawei and China Telecom Nanjing Branch and Nanjing Power Grid conducted end-to-end testing of power slices based on 5G SA network environment and real power terminals in the field test environment. Through the 5G base stations deployed by China Telecom in Drum Tower and Surabaya, the indoor, outdoor, near-end, mid-end, far-end and obstacle occlusion tests were performed respectively, and the end of the power server processing, network command transmission and power negative control terminal processing was measured. The total delay is about 35ms, the delay fluctuation is small, and the isolation of the slice is fully verified to meet the key requirements of the grid for accurate management of the load unit in milliseconds under the communication network.

Zhan Mingfei, deputy general manager of the government and enterprise customer department of China Telecom Jiangsu Corporation, said: “This successful test is a breakthrough achievement based on the SA network in the 5G industry application field. The next three parties will continue to make good use of the national major special projects and China Telecom 5G pilot. Resources, continuous joint innovation, and jointly build a 5G power ecosystem. The in-depth experiment of 5G power slicing will also accumulate experience for China Telecom to provide high-standard 5G solutions in various vertical industries.”

Gao Shengyu, deputy general manager of State Grid Nanjing Power Supply Company, said: “5G power slicing can provide important guarantees for communication systems for new business needs, new service models and new modes of operation. In the future, State Grid hopes to continue to cooperate with China Telecom and Huawei. To enhance the perception of users and equipment at the end of the grid, and continue to promote the construction of ubiquitous power Internet of Things, to provide assistance for the construction of world-class energy Internet companies with hub, platform and sharing characteristics.”

Qiu Xuefeng, general manager of Huawei’s 5G core network, said: “5G chips need to realize the on-demand definition, rapid deployment, automatic operation, end-to-end SLA guarantee and capacity opening of the network. The core network is the key link. Huawei has been at 5G very early. The network architecture evolution and slicing technology are put into research and development, and at the same time actively contact and understand the vertical industry, and promote the application of network slicing in the industry market. The successful power slice test based on 5G SA network is a key milestone for 5G application in vertical industry. DNA will serve as a reference for more industry applications.”

China Telecom, State Grid and Huawei launched the Power Slice Joint Innovation Project in September 2017. In January 2018, the “5G Network Slice Enable Smart Grid Industry Report” was jointly released, and the power slice business design was completed in June 2018. DEMO show. The results of the tripartite cooperation won the first prize in the 2018 “Bloom Cup” 5G Application Collection Competition.

After the completion of this test, the three parties will continue to deepen cooperation. In the second phase of the test, the company plans to test more intelligent application scenarios such as “smart monitoring” based on the current network user environment, and further promote 5G in the power industry.
