A method and apparatus for supporting a Short Message Service (SMS) of a Mobile Station (MS) during an idle mode in a wireless communication system are provided. An MS operation method for supporting an SMS in a wireless communication system includes receiving an SMS message from a Base Station (BS) through a ranging message in an idle mode, upon receiving the SMS message from the BS, starting a timer, while the timer operates, waitinging UpLink (UL) resource allocation for transmission of an ACKnowledge (ACK) message about the SMS message, and upon being allocated a UL resource for the ACK message transmission, and transmitting the ACK message using the UL resource.
