Radio access network slicing in 5G

Abstract

Network slicing is one of the key technologies for 5th-Generation (5G). It enables operators to construct network slices with similar qualities as dedicated stand-alone networks, but to realize them on a common physical platform. Meanwhile, the isolation among logical network slices can keep them from the negative impacts of other network slices. In this paper, we give an overview of the radio access network (RAN) slicing, and present some viewpoints on three categories of network slices. Moreover, an approach, which dynamically creates RAN slice to meet specific business and service requirements, is proposed. It does not only optimize performance and maximize resources utilization, but also shorten the creating time of slices.
