The invention provides a cooperation interference excitation method for realizing physical layer safety in the mobile communication technical field. The invention provides an excitation measure based on paid cooperation interference service according to energy finiteness and selfishness of cooperation nodes. The method comprises the steps: collecting channel state information of each cooperation node and selecting an appropriate node to carry out cooperation interference; a legal communication source node giving initial service total compensation m according to the service need of itself; carrying out gaming of the service total compensation m between the source node and the cooperation nodes by utilizing a Stackelberg gaming method; and carrying out gaming of each obtained compensation mi between the cooperation nodes by utilizing the Stackelberg gaming method. Through double gaming processes, the source node is allowed to obtain the cooperation interference service, of which the cost performance is optimal; and meanwhile, optimum allocation of cooperation power and compensation of each cooperation node is realized.
