The Bluetooth is a protocol for short-range wireless communication proposed as an open standard by five companies including Ericsson, Nokia, Intel, Toshiba, and IBM forming a consortium called Bluetooth Special Interest Group (SIG) in 1998. Since then, Lucent Technologies, Motorola, Microsoft, and 3Com have joined the SIG (Special Interest Group), which currently has more than 2000 members worldwide. As member companies continue to grow, the Bluetooth is now establishing itself as a global standard for short-range wireless communications.

The Bluetooth may transmit and receive data at high speed using a radio frequency without a physical cable for communication between various electronic devices. Bluetooth 1.0 has a data transfer rate of 1 Mbps and a transmission distance of 10 to 100 m. Therefore, compared with the Infrared Data Association (IrDA) using infrared rays, the communication distance is increased and the radio frequency of 2.4 GHz is used. In addition, the Bluetooth is a clear advantage in portable devices that consume less power due to the limited battery capacity.

In particular, the Bluetooth can transmit and receive data at high speed using radio frequency (RF) without a physical cable in various electromagnetic periods, and has the advantage that it is possible to transmit text as well as voice data in all directions without limitation of space. . In addition, with the rapid development of information and communication technology and image technology, it will be easy to transmit and receive image (image) data. Therefore, when the data communication unit 130 includes a Bluetooth transmission / reception module, data such as an image (video), voice, text and numbers may be transmitted and received.

In operation S214, this is output through the display unit 116 and / or the voice output unit 122. Thus, the telephone reception mode is started.

For example, when information on the other party's phone number and / or the other party's name, which is normally displayed on the screen at the time of receiving a phone call, is displayed on the display unit 116 (S2l4), the phone receiving mode is displayed. Begins. As another example, an alarm tone or a telephone ring may be output through the voice output unit 122 by a signal indicating the telephone reception of the mobile terminal 200 to start the telephone reception mode. As another example, the other party's phone number and / or the other party's name may be displayed through the display unit 116 for receiving a call, and an alarm tone or a telephone ring may be output through the voice output unit 122. . The information displayed on the display unit 116 may be configured to be the same as the information displayed on the display screen provided in the mobile terminal 200.

In this case, the controller 110 outputs a command selection menu through which the user selects whether or not a call is possible through the display unit 116 (S216).

If the call is selected by the user and the call is made (YES), if the video call is possible, the call is performed through voice and video transmission and reception with the mobile terminal 200, and if the call is not possible, the call is made through voice. Perform the call (S218).

In this case, when the video call is performed, a call through the output of the display unit 116 and the audio output unit 122 is performed without returning to the previous mode, but only a voice signal is received through the mobile terminal. That is, when not in a video call, the display unit 116 returns to the first mode which is the previous mode. And, since the transmission and reception of the voice signal should be performed until the end of the call, the voice output unit 122 continues to operate for the phone call. Here, the display unit 116 may be provided with a small display window for displaying a call state when the display unit 116 recovers to the first mode, which is a voice call instead of a video call.

After the call is terminated, the operation of the display unit 116 and the voice output unit 122 is completely returned to the first mode (S220).

If the call rejection is selected by the user and becomes impossible to call (NO), the mobile station returns directly to the first mode (S220). At this time, the control unit 110 transmits a call rejection signal to the mobile terminal 200 through the data communication unit 130 so that the telephone connection is blocked.

As described above, by performing wired and / or wireless data communication with the portable terminal, telephone transmission / reception is possible through the navigation device, and the caller can be more securely identified than before when the telephone is received. In addition, the mobile terminal can be controlled through the navigation device.
