Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 is an overall configuration diagram of a telephone call device in a vehicle according to the present invention.

In the car navigation system, a radio telephone 130 capable of data communication with the car navigation apparatus 110 and an adapter 120 capable of controlling the cordless telephone 130 are installed in a vehicle, and the information center is operated using a radio communication network. 140 can be accessed.

The information center 140 may receive various types of information from IPs providing various kinds of information and process the information so that the navigation device 110 may display the information. IP provides traffic information along with information calls such as news and stock weather e-mails that provide various living conveniences.

When a user operates the car navigation device 110 to request traffic information, the car navigation device 110 requests the adapter 120 to make a telephone connection to the information center 140, and the adapter 120 calls the wireless telephone 130. Call the information center 140 to establish a connection with the information center 140, receive a connection permission, and transmit the same to the navigation device 110. When the connection is completed, the navigation device 110 transmits the current location of the vehicle to the information center 140 and requests traffic information. The information center 140 receiving this command detects the location of the vehicle and sends traffic information around the vehicle in the order of the promised area from the location of the vehicle.

FIG. 2 is a flow chart showing a method for a telephone call in a vehicle according to the present invention using the apparatus of FIG.

First, a plurality of telephone numbers desired by a user are stored in a memory (not shown) in the wireless telephone 130, and the wireless telephone is mounted inside the vehicle.

In operation 210, the navigation device 110 requests a telephone connection to the adapter 120.

In step 220, the adapter 120 transmits a call connection response signal to the navigation device 110.

When the navigation device 110 requests a phone number search by pressing a phone number search button as shown in the screen shown in FIG. 3 in step 230, the adapter 120 stores the memory 120 in the memory (not shown) of the wireless phone 130. A plurality of telephone numbers are read (step 240).

When the wireless telephone 130 reads the stored telephone number and transmits the stored telephone number to the adapter 120 in step 260, the adapter 120 sends a search response to the telephone number to the navigation device 110, that is, as shown in FIG. 3. A plurality of telephone numbers are displayed on the screen as shown in step 250.

When the user selects a desired telephone number from among the telephone numbers displayed on the screen of the navigation device 110 in step 270, the telephone number is transmitted to the wireless telephone 130 via the adapter 120 and the call is automatically attempted.

The present invention is not limited to the above-described embodiment, and of course, modifications may be made by those skilled in the art within the spirit of the present invention.

As described above, according to the present invention, in a vehicle medium in which a two-way information call is possible in a car navigation system, a wireless telephone can be easily communicated using a screen in a vehicle.
