For the interference problem in the Femtocell network, a power control strategy is proposed based on the Stackelberg game and bargaining game theories. Firstly, a utility function is given to maximize system capacity and utility fairness. Then, under the condition of maximizing the utility of the Macrocell users, considering the revenue of the Femtocell users, a stackelberg model is proposed. After that, considering the utility fairness and minimum quality of service requirement between Femtocell users, the Kalai-Smorodinsky bargaining solution based on the bargaining game is given, and the existence and uniqueness of bargaining solutions are proved. The Lagrangian multiplier method is used to give the optimal price of the Macrocell, which ensures the utility of the Macrocell users. The simulation results show that the strategy can meet the minimum quality of service requirements of Femtocell users and ensure the fairness between the Femtocell users. Besides, the benefits of the Femtocell network can also be guaranteed.
