Abstract: PURPOSE: A method for recovering lost signals between processors of a mobile communication exchange is provided to improve a sliding window protocol used during IPC(Inter Processor Communication), in order to enhance a recovery function when signals are lost, thereby stably operating a system. CONSTITUTION: A mobile communication exchange decides whether messages are full within a Tx window slide(S101). If not, the exchange transmits the messages to a receiving side(S103). The receiving side decides whether the messages are received(S105). If so, the receiving side decides whether a sequence number of a substantially received message is equal to a sequence number of an expected message(S107). If so, the exchange reads the sequence number of the expected message(S109). If the two numbers are not the same, the receiving side decides whether a difference subtracting an expected pure number from the sequence number of the received message is bigger or smaller than a max slide(S111). If the difference is within the max slide, the receiving side includes an expected message value in an NEG(Negative Ack)-type signal, and transmits the message(S113). The exchange decides whether a re-transmission request ACK signal arrives(S121). If so, the exchange decides whether the signal is an NEG-type signal(S123). If so, the exchange takes out a message from a spare Tx window slide or the Tx window slide, and attempts re-transmission.
