The present invention relates to a method of displaying a location of a wireless terminal, and more particularly, to an apparatus and a method for displaying a location of another wireless terminal user on a car navigation system by a wireless terminal subscriber having a car navigation system.

In general, a user using a wireless terminal performs various operations such as registering a terminal in a base station and synchronizing with the terminal in the initialization step of the terminal by turning on the power of the terminal. At this time, the base station registers and stores the location of the terminal, and when a case of calling a registered terminal occurs, a call signal is generated to make a call. However, the one base station has registration data of the terminal belonging to the base station but has not yet informed the position of the terminal when another user desires to know the position of the terminal user. Although the present invention has been described in terms of the location of the terminal and the location of the base station where the terminal is currently registered and the information of the base station, it is not indicated on the map. Furthermore, a user who does not know much geographic information has a problem that even if the location of the base station and the base station information are displayed on the terminal, it becomes useless.

Accordingly, it is an object of the present invention to provide an apparatus and method for displaying location information of a user who has opened his / her location information from a base station on a map.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding the reference numerals to the constituent elements of the drawings, it should be noted that the same constituent elements are denoted by the same reference numerals even though they are shown in different drawings. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. It will be obvious to you. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 is a schematic configuration diagram of a system including a wireless terminal, a base station, a car navigation system, and a GPS satellite according to the present invention.

The first terminal is registered in the first base station, and transmits location notification data for informing the first base station of the position of the terminal to the first base station. The first base station receives the location notification data from the first terminal and transmits the location notification data, the location data of the first base station, the address data, and the serial number data to the control station. The control station stores the position notification data of the first terminal registered in the first base station and the position data of the first base station in which the first terminal is registered in the memory. In addition, if a message requesting location data of the first terminal is received from the second base station, the control station checks whether the first terminal is registered, and if the first terminal is registered and the location notification is open, 1 position data to the second base station. The second terminal has an interfacing part for interfacing with the car navigation system and transmits a message requesting position data of the first terminal to the second base station and is registered in the second base station. The second base station receives a message requesting the position data of the first terminal from the second terminal, transmits a position data request message to the control station when the message is received, receives position data from the control station To the second terminal. A CAR NAVIGATION SYSTEM (hereinafter referred to as " CNS ") is interfaced from the second terminal and reads out and displays map data corresponding to the position data when the position data is transmitted from the second terminal, Is displayed.

First, a process of transmitting location notification data to a terminal user and storing the location notification data in a control station will be described as follows.

The first terminal user transmits data of his telephone number and OPEN to the first base station, for example, in order to open (OPEN) its position to the other. The above example may be something like " 011-222-3333-OPEN ". The first base station receiving the signal transmits the telephone number and the open data to the control station. Then, the first base station transmits the position data of the first base station together. The location data may be obtained by receiving and calculating GPS data from a GPS (Global Positioning System) satellite, or the base station may initially store its location in the base station memory. The location data includes longitude and latitude data, address data, and a base station serial number. The control station receiving the position data and the position notification data stores the data in the memory. The memory map stored in the memory is shown in Table 1, for example.

Base station serial number Phone number Location notification data Base station location data Base station address data One 1555 011-222-3333 OPEN E-37.888 N-37.222 Myong-ri-dong, Jongno-gu, Seoul 2 1564 017-333-4444 CLOSE E-39.888 N-37.999 Gyeonggi-do Gyeonggi-do 3 1573 019-444-5555 OPEN E-20.888 N-30.222 Busan Haeundae-gu Middle East ... ... ... ... ...

The control station stores position data and position notification data of the terminals registered in the respective base stations by the above-described process.

2 is a control flowchart for displaying a location of a wireless terminal user according to an embodiment of the present invention.

In the second terminal having the interface unit for interfacing with the CNS (CAR NAVIGATION SYSTEM) in a state where the location data and the location notification data are stored by the above-described procedure, the location data of the first terminal is received and displayed on the CNS. .

If the second terminal transmits a message requesting the location data of the first terminal in step 200, the second base station to which the second terminal is registered transmits the location data request message to the control station. The location data request message to be transmitted at this time is, for example, " 011-333-4444-POS ". If the control station receives the message requesting the location data in step 210, the control station searches the memory in step 220 and checks whether the corresponding phone number is registered. If the corresponding telephone number is not registered, an error message is transmitted in step 241. The error message is, for example, " the corresponding number is not registered ". If the corresponding phone number is registered, it is checked whether the location notification data is opened (OPEN). If the location notification data has not been opened, the mobile terminal proceeds to step 241 and transmits a message such as " Location notification of the telephone number is not opened. &Quot; If the location notification data is opened, the location data and the address data as shown in Table 1 are transmitted to the second base station in step 240. Then, the base station transmits the received location data and address data to the second terminal. At this time, the second terminal checks in step 250 whether the location data is received. When the location data is received, the address data received together is displayed on the display unit as, for example, " The user of the corresponding telephone number is located in Myolyon-dong, Jongno-gu, Seoul. In step 260, the second terminal transmits location data to the CNS through the interface unit. If the position data is not received and an error message is received in step 250, the received error message is displayed on the display unit. The error message is "The corresponding number is not registered." Or "Location notification for this phone number is not open."

When the location data is transmitted to the CNS through the interface unit of the second terminal in step 270, the CNS reads the map data corresponding to the location data in step 280. [ In step 290, the CNS displays a point corresponding to the received position data on the displayed map.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention. Therefore, the scope of the present invention should not be limited by the described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.

As described above, according to the present invention, the position data of the terminal is displayed using the car navigation system, so that the user can easily grasp the position of the terminal user who wants to know the user on the map.
