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 industries to achieve the “Internet of Everything” vision
of ubiquitously connected, 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, vendors, and vertical
industries 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 technologies, and the
impacts for vertical industries. This white paper describes the thinking on network slicing in 5G
