PURPOSE: A hands-free mode conversion system is provided to convert into a hands-free mode without an encoding algorithm, in order to connect a data connector only to a hands-free device without connecting both ear jack and data connector, thereby using the data connector in the hands-free mode. CONSTITUTION: A hands-free terminal(200) receives an intrinsic number from a cellular phone(100) to transmit the intrinsic number through wireless data communication, receives a key code corresponding to the intrinsic number, and converts the cellular phone(100) in hands-free method. A data server(300) receives the intrinsic number of the cellular phone(100) to output the intrinsic number to an encoding algorithm-embedding hands-free unit(400), and receives the key code from the hands-free unit(400) to transmit the key code to the hands-free terminal(200). The hands-free unit(400) receives the intrinsic number, and outputs the key code corresponding to the intrinsic number. |
