Method for using a program in common by use of board id in mobile communication system

PURPOSE: A method for sharing a program using a board ID in a mobile communication system is provided to unify an execution file as one by generating and managing one shared execution file using target board IDs about a plurality of target boards. CONSTITUTION: A BSM(Base Station Management) executes a shared execution file for a plurality of target boards(302). Processors of target boards read each ID of a plurality of target boards, assign the read ID to a random variable, and stores the variable in a uniform region of a memory(304). The processors of the target boards initialize a hardware according to the IDs of the target boards(306). The processors of the target boards initialize an OS(Operating System) executed in the target boards to be suitable for a corresponding target board(308). The processors of the target boards branch to a board-classified process routine according to the IDs of the target boards and perform a corresponding application program(310).
