All above have led to greater demand for wireless resources, which constitute a contradiction with the limited resources. This paper studie how to use the limited wireless network resources to do the rational and effective allocation based on the common utility framework, then model and solve the optimization problem by the noncollaborate game theory.Traditional design of resources allocation and optimization can acchieve higher in techniques target, but lack of a reasonable explanation for user behavior. This paper designs a punishment network management mechanism to suppress the users selfish request, which can meet the needs of user connections and also control the congestion level of the network. Through simulation for the optimal solution of the heterogeneous networks resource allocation game in Matlab,it is verifiable that the dynamic resource allocation mechanism of this article can not only guarante the QoS experience for a variety of user connections, but also can improve the networks entire utility.
