As one of the key technologies of mobile communication network optimization, power control will directty affect the optimization result of the mobile communication network. Based on the study of power control principle, a simplified model is proposed from the viewpoint of power control and rate control. The Grad-PSO algorithm is a typical swarm intelligence algo- rithm, and it has been widely used in engineering optimization. Through function optimization simulation, the algorithm shows advantages of high convergence speed, accuracy and computational arithmetic. The algorithm is used to optimize the power con- trol model. Simulation results show that there is an optimal solution and the optimization of power control model is well real- ized. The results show that the method is feasible and effective.
