A 5G Network Slice Based Edge Access Approach with Communication Quality Assurance

Abstract

With the development of various vertical industry services such as autonomous driving, energy Internet, and smart cities, mobile communication networks need to provide users with ubiquitous high-speed access while using limited network resources to provide differentiated and customized services, the 5G network satisfies the requirement of the future . However, for the access network, there are many types services accessing the network. In order to provide users with diverse personalized services, network slicing scheme is introduced into 5G network. Network slicing is based on the technology of network function virtualization, which can establish multiple virtual private networks in the device according to the needs of users. Each slice is a private network, and different virtual networks are kept isolated from each other. This article studies the access network of the 5G network, in order to ensure the quality of user access, we study the mapping scheme of network slices and NFV to ensure the communication quality of access networks of different user types. Finally, we perform some simulations to verify the proposed method, and the result shows that our proposed can ensure the communication quality for the users which connect into the 5G network.
