Abstract

The invention relates to a spectrum resource allocation method based on utility function and price mechanism; the spectrum resource allocation method is suitable for a virtual cellular network in wireless communication. The method comprises the steps of firstly, obtaining signal gains from a base station by user terminals; calculating the number of optimal sub-carriers which are allocated to all the user terminals serviced by a cellular network operator and calculating the number of optimal sub-carriers of all the user terminals serviced by an nth virtual service provider by a network virtualization controller; calculating the spectrum resource supply amount of the cellular network operator and the demand amount of all virtual service providers for the spectrum resource by the network virtualization controller; judging whether the data is in accordance with the requirements or not by the network virtualization controller; if yes, obtaining the optimal spectrum resource allocation results of all the user terminals; if not, continuously carrying out iterative operation. The method is simple and good in allocation effect, and the aim of maximizing the incomes of the cellular network operator and the virtual service providers can be achieved.

Description

technical field [0001] The invention relates to a method for allocating spectrum resources, and is especially suitable for realizing the one-to-many utility function and price mechanism-based utility function and price mechanism for cellular network operators and virtual service providers in a virtual cellular network in the field of wireless communication technology. Spectrum resource allocation method. Background technique [0002] With the continuous growth of the number of intelligent user terminals UE (User Equipment) and the volume of broadband mobile multimedia services, Internet Service Providers (ISPs) need to adopt new information and communication technologies ICT (Information and Communication Technology) to improve user terminal The flexibility of wireless access and the utilization efficiency of limited spectrum resources. Wireless Network Virtualization technology WNV (Wireless Network Virtualization) provides an effective solution to achieve this goal. In W...
