The invention provides an intelligent simulation system of a mobile terminal and a simulation method based on the intelligent simulation system of the mobile terminal. The intelligent simulation system of the mobile terminal comprises a behavior collection terminal, a simulation execution module, a behavior analysis module, a behavior display module and a strategy module, wherein the behavior collection terminal and the simulation execution module are positioned on the mobile terminal; and the behavior analysis module, the behavior display module and the strategy module are positioned on a remote service side. By use of the simulation method, the basic data of the user is obtained through the behavior collection module and is processed by the remote service side to obtain the behavior model of the user, and the behavior model of the user is converted into a strategy command form to be issued to the simulation execution module for simulation. By use of the intelligent simulation system, which is provided by the invention, of the mobile terminal, on the basis of analysis for the behavior data of the mobile terminal utilization of the user, the real utilization behavior of the user is simulated, an application in the mobile terminal is automatically executed under a situation of unattended operation, and the behavior that the user uses the mobile terminal at present is simulated to achieve the purposes of disguise and enemy confusing.
