A Method of Transport Abstraction for 5G Radio Access Networks

In the fifth generation mobile technology era, networks which cover a variety of requirements will be constructed as virtual networks (slices) by giving them appropriate resources taking into account each service's requirements. To create a slice, the management and control of a range of physical resources within a heterogeneous network is a crucial issue. One key technique to enable this is a resource abstraction method. Also, it is important to adjust the resource abstraction level to meet the service requirement parameters set by the slice orchestrators or network operators. In this paper, we have proposed abstracted resources representing services' requirement parameters in a 5G Radio Access Network (RAN), and a method for abstracting resources from many types of physical network resource. In addition, a resource allocation procedure using the proposed abstracted resources has been introduced.
