PURPOSE: A duplication method for admitting fault in real time in a wireless communication system is provided to perform a successive service as to a call in progress as well as a set call when the fault is generated during the operation of a system by transmitting a changed item of a memory to a standby side while application tasks are operated by a message unit and logging a message for recovery when the application tasks are switched. CONSTITUTION: When performing an initialization, a registration message for registering its storage region is transmitted to a duplication module(201). An IPC(Inter Processor Communication) terminal receives an external message(202), and a corresponding application block processes the received message(203) and transmits backup data to the duplication module(204). It is judged whether the backup data are transmitted to the standby side(205). If the backup data are transmitted to the standby side, a check point message is transmitted to the duplication module(206).
