Claim:
A mobile communication terminal including a SMS (short message service) system comprising a message sending module which receives from a message sender a message content, a telephone number of a mobile communication terminal of a designated message recipient, and a message mode selected by the message sender, generates from location information received from the message sender an SMS message containing the message content, mode identification information based on the message mode, and the location information if the message mode selected by the message sender is a location-based message mode rather than a general message mode, and sends to an SMS server the generated SMS message which is set to be forwarded to the telephone number of the message recipient's mobile communication terminal as a destination, wherein the mode identification information comprises a single parity bit, the single parity bit having a first value if the message mode is the location-based message mode, and having a second value if the message mode is the general message mode, the single parity bit indicates whether the SMS message is to be processed by a general message processing unit or a location-based message processing unit, and wherein the message sending module comprises: an input unit which allows the message sender to input the message content and the telephone number of the mobile communication terminal of the designated message recipient; a mode selection unit which allows the message sender to select the general message mode or location-based message mode; a location information management unit which receives the location information from the message sender when the location-based message mode is selected in the mode selection unit; an SMS message generation unit which generates an SMS message containing the message content inputted through the input unit and mode identification information based on the message mode selected through the mode selection unit, and, if the selected message mode is the location-based message mode, further containing the location information inputted through the location information management unit; and a message transmission unit which transmits to the SMS server the generated SMS message which is set to be forwarded to the telephone number of the message recipient's mobile communication terminal as a destination.
