Abstract

The invention discloses a cellular heterogeneous network resource allocation method based on game theory. The method comprises the following steps: firstly working out an optimal solution of the bandwidth allocation under a centralized decision-making mode by using a Stackelberg game method, and then designing a cellular heterogeneous network dynamic resource allocation scheme based on the Stackelberg game by considering the Nash equilibrium condition under a decentralized decision-making mode; researching the maximum return of a cellular heterogeneous network to work out the Pareto optimalityof the bandwidth allocation; and finally computing the system interference of a macro base station, and comparing the returns and interference situations of the network under the centralized mode andthe decentralized mode. The cellular heterogeneous network resource allocation method disclosed by the invention proves that the Pareto optimal capacity equilibrium is existent between resource providers through a game analysis method, and obtains an optimum pricing strategy of the resource providers based on the Pareto optimal capacity equilibrium; and at last, the energy efficiency and the spectrum efficiency in a network system can be sufficiently utilized. A micro base station satisfies a traffic demand of a user at the backhaul stage through the allocation to the max.
