Key Issues of Future 5G Network Slicing Technology

5G is a wide band, ubiquitous, intelligence, integration and green energy network. It will meets the demand of ultra-high traffic density, high connection density and high mobility. In the core network, the key technologies will be based on the achievement of NFV and SDN. To achieve highly diverse user and network performance, the recognized the key 5G network technology of slices are studied in the paper. Based on the analysis of slices concept, features, the future functional requirements, the paper discusses the network slices architecture and performance in view of NFV and SDN.
