The network slice is an important enabling technology of the 5G network, and can meet specific requirements of different service types, service scenes and vertical industries. A network slice is an end-to-end logical subnet, and relates to a core network (control plane and user plane), a radio access network, an Internet Protocol (IP) bearer network, and a transport network, and requires cooperation in multiple fields.
