In a network virtualization environment

the pricing strategy of network operators for spectrum allocation using the static game algorithm and the spectrum allocation method of every virtual operator using the static and dynamic game algorithms are proposed on the basis of a Stackelberg game model.In addition

the Nash equilibrium point when the profit of each operator is the maximum is derived.This method can maximize the revenues of network operators and virtual network operators simultaneously.Simulation results verify the effectiveness of the algorithm and the existence of Nash equilibrium point.
