5G Service-Guaranteed Network Slicing White Paper Issue V1.0 Date 2017-02-28 China Mobile Communications Corporation, Huawei Technologies Co., Ltd., Deutsche Telekom AGđVolkswagen Previous generations of mobile networks enabled voice, data, video, and other life-changing services. In comparison, 5G will change our society by opening up the telecom ecosystem to vertical industries. 5G will help vertical indus tries to achieve the “Internet of Everything” vision of ubiquitous ly connect ed, highly reliable, ultra-low latency services for massive number of devices. Service-guaranteed network slicing introduced in this white paper is one of the essential features for 5G to achieve this vision. Key players from operators, vendor s, and vertical indus tries have come together to establish a common understanding on service-guaranteed network slicing in terms of the vision, end-to end (E2E) solution, key enabling technol ogies, and the impacts for vertical indus tries.

IoT requires support for a diverse range of service types, such as eHealth, Internet of Vehicles (IoV), smart households, industrial control, environment monitoring, and so on. These services will drive the rapid growth of IoT and facilitate hundreds of billions of devices to connect to the network, which also conceives the “Internet of Everything” vision especially from vertical industries. The requirements for IoT services are also very • Service diversity The services foreseen in the 5G era fall into three typical scenarios: enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low Latency Commu-nications (URLLC), and massive Machine Type Communications (mMTC). eMBB focuses on services characterized by high data rates, such as high definition (HD) videos, virtual reality (VR), augmented
