Abstract

PURPOSE: A call simulator device in a mobile communication system is provided to configure an operator computer that is connected to at least more than two multi port cards and controls call simulation of a mobile communication terminal to supply a controlled result as graphics, and to configure mobile communication terminal cradles that receive connection states and control signals of mobile communication terminals to supply the states and the signals to the mobile communication terminals, so as to simultaneously perform many call simulation processes. CONSTITUTION: If a program driving of an initial call simulator is requested, a controller reads data from a hard disk to load an initial program(200). The controller transmits graphic data to a graphic processor to display an initial state and a screen(202). After the screen is outputted, the controller checks whether terminal recognition is requested(204). If not, the controller checks whether a signal inputted by a user from an external connector is a reserved test(206). If so, the controller reads corresponding data to output the data on the screen(208). The controller updates the data according to a key signal inputted on the screen(210).
