There must exist interference in the two-tie networks of Femtocell and Macrocell when they share the spectrum resource. In this paper,emphasize the study on the effect of power control to interference suppression by using non-cooperative game pattern to describe the system. Based on the analysis of the Nash equilibrium in Stackelberg game,a link protection method which optimizes Femtocell per-formance is combined to decrease the number of FUE not meeting the SINR requirements. Simulation results show that the modified algo-rithm can achieve the desired results and effectively improve the system performance.
