1. A processor duplexing apparatus in a mobile communication system, comprising:

  • an active board; and

    a standby board, wherein the boards have a real time operating system (RTOS) which detects a need for and executes a dual switching operation, wherein each of the active board and the standby board includes;

    a processor for loading the RTOS which performs a duplexing operation without intervention of application software;

    a memory circuit to store at least one of programs or data required for system operation;

    a PCI controlling circuit to directly access a memory of a self side board at a time of dual switching, and to dump contents of the memory of the self-side board to a memory of an opposing board;

    an ethernet controller to transmit data between the self-side board and the opposing board through an ethernet channel; and

    a duplexing control to prevent memory access collision between the self-side board and the opposing board.
