It is possible to receive voice service using the frequency public communication or text service using the personal mobile communication using the frequency common communication (TRS) and personal mobile communication (PCS) network.

The present invention corresponds to a vehicle information terminal using a personal mobile communication (PCS) network.

2 illustrates a block diagram of a vehicle information terminal using a conventional personal mobile communication network.

This includes a GPS receiver 26 for receiving a satellite signal and calculating the position, speed and time of the vehicle, a CPU 21 capable of calculating and converting the GPS signal of the GPS receiver 26 and processing the information, and a program memory. In-flash memory 24, SRAM 25, which is a data storage device, a communication port 22 connected to a personal mobile communication terminal (hereinafter referred to as a cellular phone; PH), a liquid crystal capable of displaying letters, numbers, pictures, symbols, etc. Screen display unit 27, the liquid crystal display

And an external input unit 28 for operating the display screen of (27), a power supply unit 23, and the like.

The conventional personal mobile communication vehicle information terminal 20 configured as described above is a communication port.

22 and the mobile phone PH are connected by a connection cable, the position information and the vehicle state received by the GPS receiver 26 are transmitted through the mobile phone PH, and the signals received from the base station are processed by a computer, respectively. Has the ability to send to the user.

As such, the position and state of the vehicle received through the mobile phone PH are checked by the control center, the vehicle is searched for the optimum vehicle, and the vehicle is arranged.

However, the conventional vehicle information terminal for personal mobile communication has been inconvenient because there is no port for another external access device such as a barcode reader or a printer.

Accordingly, it may be provided with a separate expansion port, which is cumbersome because it is cumbersome to install and many cables, such as a cable of a mobile phone (PH) connected to the existing communication port 22 or a cable for supplying power, are tangled with each other There was a problem that hurts the aesthetics of the driver's seat.

In addition, the upgrade of the product was required to replace the chip on the circuit board, which was inconvenient, time consuming and costly.

Therefore, the present invention was devised in view of the above problems of the conventional personal mobile communication vehicle information terminal, and an object of the present invention is to facilitate the use of an external access device as well as to remove the complexity of installing various cables inside the vehicle. It is to provide a vehicle information terminal for a personal mobile communication network equipped with Bluetooth to consider aesthetics, improve usability, and facilitate product upgrade.
