The present invention relates to a system and method for providing location information using a mobile communication terminal having a radio frequency identification tag reader. More particularly, the present invention relates to radio frequency identification of a mobile communication terminal with respect to a radio frequency identification tag attached to various points. The present invention relates to a system and a method capable of providing a location of a mobile communication terminal by using the tag as a reader.

In modern society, mobile communication terminals are widely used as a necessity for modern people as a means of convenient communication without regard to street or place. Recent mobile communication terminals have provided various functions as well as conventional mobile communication services as the resource and resource capabilities of the processor and memory are expanded.

As an example, the present invention may be utilized in various ways such as a vehicle navigator serving as a road guide to a user or a location tracking device for children, the elderly, travelers, and the like, including a function of providing location information to a mobile communication terminal. However, the current mobile communication terminal providing such a function requires the user to purchase a mobile communication terminal additionally equipped with an expensive additional device in order to use the location information providing service, or use a separate location verification service. Because of the problem of having to pay a lot of additional costs, it is difficult to be widely used.

An example of a method of implementing a conventional location information providing service is shown in FIG. 1.

1 is a schematic diagram illustrating a base station-based location tracking system 100.

In order to maintain a communication function, a mobile communication terminal constantly searches for a base station in which it is currently located and exchanges signals with the base station. Accordingly, the base station-based location tracking system 100 can track the location of the mobile communication terminal in the area managed by the base station by utilizing the location information on the base station currently communicating with the mobile communication terminal.

For example, when the second mobile communication terminal 140 requests location information to confirm the location of the first mobile communication terminal 110, the communication service provider 130 may determine the base station of the base station that is closest to the first mobile communication terminal 110. Search for a location. Then, the first mobile communication terminal to the second mobile communication terminal 140 by displaying the position of the first mobile communication terminal 110 on the electronic map provided to the second mobile communication terminal 140 based on the retrieved data. Provide location information of 140. Using the base station-based location tracking system 100 has the advantage that the location of the mobile communication terminal can be known in a relatively inexpensive manner.

However, in the base station-based location tracking method, since the area (cell) covered by one base station is relatively large (eg, within 1 km in diameter with respect to the base station), the precision of the location information of the mobile communication terminal 110 is considerably inferior. Therefore, there is a disadvantage in that it is difficult to grasp the specific location of the person who owns the mobile communication terminal.

As another location tracking method to compensate for this disadvantage, a tracking system using GPS satellites is used. A mobile communication terminal equipped with a GPS receiver can calculate its position by substituting signals received from a plurality of GPS satellites into triangulation. The satellite receiver function of the Global Positioning System (GPS) enables more accurate location information (only 5 to 100 m error) than the base station-based location tracking method.

However, in order to use the GPS-based location tracking system 200, an expensive GPS antenna and a reception device must be built in a mobile communication terminal, and indoors, highways, undergrounds, tunnels, etc., which cannot receive satellite signals. In many environments, location tracking is difficult.

Accordingly, there is a demand for a new technology capable of receiving specific location information of a mobile communication terminal in a manner that does not require a great cost, and stably providing location information regardless of a radio wave reception environment.

The present invention has been made to solve the problems of the prior art as described above, and an object of the present invention is to provide a location of a mobile communication terminal using a mobile communication terminal.

Another object of the present invention is to generate location information of a mobile communication terminal with more precise location information by calculating a combination of a plurality of location information.

Still another object of the present invention is to enable the mobile communication terminal to be used as a navigator by allowing a mobile communication terminal having a positioning function to identify the position of the mobile communication terminal by itself.

Another object of the present invention is to enable the location information of the mobile communication terminal to be shared with the second mobile communication terminal, so that when the second user wants to know the location of the first user, the location information should be requested or received. You can avoid the hassle of doing.

Another object of the present invention is to share the location information of the mobile communication terminal with others, it is easy to tell others their location when in an emergency situation such as a criminal situation.

In order to achieve the above object and to solve the above-mentioned problems of the prior art, the position information providing system using a mobile communication terminal according to the present invention, the unique identification information of a plurality of radio frequency identification tag and the position corresponding to the unique identification information A location information database for storing information, a location request request unit for receiving location request information of a second user from a first user and transmitting a request for transmitting location information to a mobile communication terminal of the second user, the mobile communication terminal An identification information receiving unit for receiving unique identification information on the radio frequency identification tag from the radio frequency identification tag reading unit, receiving the radio frequency signal from the radio frequency identification tag, and reading the unique identification information from the radio frequency signal; Image is received using the received unique identification information. The positioning information generation unit for generating location information of the mobile communication terminal from the location information database, and provides positioning information to send to the first user positioning information the generated characterized in that it comprises a.
