PURPOSE: A method of giving a multi port short message transmitting and calling service and a method therefor are provided to collectively process interrupt services when carrying out the short message transmitting and calling service based on many wireless modems, thereby improving performing speed. CONSTITUTION: A system inputs interrupt request information from many devices, and buffers interrupt request information in a buffer for the inputted interrupt request information(502). An interrupt request signal is outputted by performing an OR operation. The buffer outputs the stored interrupt request information in response to a reading request signal from a CPU. The CPU reads the buffered interrupt request information through a bus, and simultaneously understands devices requesting to receive an interrupt service(504). The CPU processes the interrupt service as many as the number of the devices requesting to receive the service(506). |
