Abstract
A method for transmitting data in a data communication system having a mobile terminal and a transmitting/receiving terminal is enclosed. The method includes the steps of establishing a voice communication channel between the mobile terminal and a receiving data terminal in the data communication system set to a Voice mode, setting the data communication system to a Data mode without disconnecting the voice communication channel by transmitting a first connection request and a telephone number of the receiving data terminal by the transmitting data terminal to the mobile terminal, establishing a data communication channel between the transmitting and receiving data terminals, and transmitting data to the receiving data terminal through the data communication channel. By sending a receiving side telephone number to the mobile terminal together with a connection request signal (ATD command) as shown in the data communication method according to the present invention, a user can transmit or receive data more conveniently during the wireless conversation. The mode of the communication system can simply be converted from a Voice mode to a Data (Fax) mode by transmitting a ATD command together with a receiving side telephone number so that it can provide a substantial convenience to a user when transmitting or receiving data during the wireless phone conversation.
