METHOD FOR CONFIRMING A LOACTION AND SYSTEM THEREFOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system, and more particularly, to a location determining method using a dedicated terminal for identifying a location of an infant and an incompetent person without decision making ability.

In general, a mobile communication system provides a mobile communication service by gathering a plurality of service areas each transmitting and receiving a radio wave having an effective strength, adjacent to each other. The service area of each base station is called a cell. Here, the mobile communication service is to enable the mobile communication terminal to communicate while moving between a plurality of cells.

On the other hand, the mobile communication terminal is wirelessly connected to the mobile communication base station that manages a predetermined cell area to perform voice call and data communication through the exchange. The exchange exchanges location information on the mobile communication terminal connected to each base station in the VLR (Visitor Location Register) and the HLR (Home Location Resister) to confirm which cell each subscriber terminal is currently located in in which service area. By setting the path, it is possible to track the real-time movement path of the mobile terminal user. That is, it is possible to check which cell area the plurality of subscribed terminals are currently located in and to which direction and distance from the antenna of the cell.

Recently, a location based service (LBS), which detects a location of a mobile communication terminal user in real time and automatically transmits various information about a corresponding area to the mobile communication terminal, has been implemented. Various application services or additional services have been developed and provided to provide such location-based services.

One of the current position detection methods of a mobile terminal user is a position tracking system using a Global Positioning System (GPS). This conventional technology can be applied to all mobile communication terminals using GPS, and all the areas where GPS is supported are included in the position for checking the location.

Meanwhile, an example of an application service using the GPS technology of the mobile communication terminal may include a method of tracking location information of an infant.

The infant location tracking system using the GPS technology and the mobile communication terminal is shown in FIG. 1. Referring to FIG. 1, the infant's location tracking system is a GPS for transmitting / receiving GPS information to and from a guardian's mobile communication terminal 10 equipped with a GPS transceiver and a guardian's mobile communication terminal 50 capable of determining a location of the guardian. Each base station 20, 40 which connects the communication line between the satellite 30, the protected mobile communication terminal 10 and the protected mobile communication terminal 50.

First, the GPS transceiver mounted on the mobile communication terminal 10 receives signals from at least three GPS satellites 30 and calculates location information of the mobile communication terminal. Then, the calculated position information is automatically passed through the base stations 20 and 40 using the mobile communication network, and then transmitted to the corresponding mobile communication terminal 50 requiring the location information of the mobile communication terminal 10. As such, recently, a GPS transceiver is embedded in a mobile communication terminal to grasp position information of the mobile communication terminal through the GPS transceiver.

Etc.

As described above, when the anti-lost product using the sensor device is conventionally used, the product is caused by a gap between the guardian and the guardian, and there is a limitation in that its location cannot be tracked. In addition, a location tracking system using GPS technology requires that the guardian always carry a mobile communication terminal equipped with GPS transmission and reception.

If GPS technology is used to prevent the loss of children, there is a problem in that the guardian has to purchase a GPS mobile communication terminal separately for the ward. In addition, when a mobile communication terminal equipped with a GPS transceiver is used, it is difficult to carry a guardian such as an infant at all times due to its size and weight.

And even if the GPS service is required in a limited area, such as an amusement park, and the service does not need to be used continuously for more than tens of hours, the GPS transceiver continues to send and receive location information, so unnecessary GPS service is continuously performed. This may cause a user to bear a GPS service fee, for example.

Accordingly, the present invention has been made to solve the above problems, by providing a dedicated terminal to determine the position and direction of the ward, the position to enable the position check without a separate operation of the ward with the dedicated terminal Its purpose is to provide an identification device and method.

In addition, the present invention provides a positioning device that can reduce the economic burden by installing an infrastructure network in a place (eg, amusement park) jurisdiction over a particular area and by renting a cheap and portable dedicated terminal used in the one specific area and The purpose is to provide a method.

In the present invention for achieving the above object, a positioning system for providing the tracking terminal with the location information of the target terminal using a mobile communication network, the tracking terminal and the target terminal is wirelessly connected within a predetermined service area; A base station controller for transmitting and receiving a corresponding communication signal, a base station controller for transmitting a signal including identification information of the target terminal to the plurality of base stations when a location request is received from the tracking terminal; The signal corresponding to the identification information included in the signal is transmitted, and the base station controller is characterized in that the location information of the target terminal through the signal received from the target terminal to transmit to the tracking terminal.

The present invention also provides a location checking method for providing location information of a target terminal to a tracking terminal using a mobile communication network, the method comprising: transmitting a paging signal in response to a location service request from the tracking terminal; Transmitting an access signal in response to the paging signal, identifying a communication resource for a current communication area in which the target terminal is located from the access signal, and determining a fixed location of the identified communication resource. And providing the current location information of the target terminal to the tracking terminal.

Referring to FIG. 3, the positioning system may include, for example, a plurality of base station transceiver subsystems (BTSs) 110 and a base station controller (BSC) within a specific service area 120, such as an amusement park. 100). That is, the location of the guardian according to the embodiment of the present invention is performed by using a general mobile communication network.

 Next, reference is made to FIG. 4 to describe in detail the configuration of a system for locating a protected person within a specific service area shown in FIG. 3. 4 is a block diagram of a system for locating a guardian according to an embodiment of the present invention.

First, the base station 110 forms a cell which is one communication service area by transmitting and receiving a communication signal according to the present invention by wirelessly connecting the target terminal 200 and the tracking terminal 210. That is, the base station 110 divides a predetermined service area into a plurality of cells to manage the corresponding cells. The base station controller 100 serves as, for example, a central information center, and is responsible for managing and controlling a plurality of base stations 110 within a specific service area. The target terminal 200 is located in a communication area in which a specific service area is divided into a plurality of cells. If the guardian wants to check the location of the guardian, the positioning method according to the present invention transmits signals transmitted through the tracking terminal 210 carried by the guardian through the base station 110 to all base stations through the base station controller 100. This is done by forwarding 110 to the paging signal. Then, the target terminal 200 transmits the access signal in response to the paging signal from the base station 110 located in the cell.

Thereafter, at least three base stations 110 around the target terminal should be used to receive the access signal from the target terminal 200. Through this, the base station controller 100 determines that the target terminal 200 is located in the cell area controlled by the base station 110 located in the three cells having the largest signal strength in response to the access signal. ) Transmits the location information on the tracking terminal 210.

According to the present invention, the location information of the target person wearing the target terminal is provided when the location service of the target person is requested using the tracking terminal possessed by the guardian in the specific service area according to the present invention.

When the location checking system configured as described above requests the location service according to the present invention, the location information of the requested target terminal is detected and the location information of the target terminal is provided to the requested tracking terminal. The process of detecting and providing the location information of the target terminal will be described in detail later. To this end, it will be described with reference to FIG. 5, which is a signal flow diagram according to a process for detecting and providing the location information of the guardian according to an embodiment of the present invention.

For example, in the case of a lost child in an amusement park, a description will be given of a positioning method that allows the guardian to quickly track the location of the lost child to find the lost child. To this end, an area such as an amusement park is divided into a specific service area so that a general mobile communication network can be used, and an infrastructure network is installed, and a target terminal and a tracking terminal as shown in FIG. Rent. The tracking terminal may be carried by the guardian, and the target terminal is worn by the guardian.

First, the tracking terminal 210 at the request of the location check service for receiving the location information of the protector wearing the target terminal 200 by the guardian, identification information which is a unique number of the target terminal 200 from the guardian in step 500. Get input. Then, the tracking terminal 210 performs the transmission including the identification number of the target terminal 200 in step 510.

In response to the call, the call signal is transmitted to the base station in step 520. In other words, when a guardian who wants to receive the current location information of the target terminal 200 attempts to call a phone number for using the location service, the phone number includes the identification information of the target terminal 200 to identify the base station. It is transmitted to the base station controller 100 via.

Then, in step 530, the base station controller 100 generates a paging signal to which the identification information of the target terminal 200 is added in response to the call from the tracking terminal 210 and transmits the paging signal to all base stations. In other words, the paging signal is transmitted by adding a phone number for using the location service providing the location information of the target terminal 200 and a unique number assigned to the target terminal to the paging signal.

When the target terminal 200 receives the paging signal according to the transmission of the paging signal, the target terminal 200 analyzes the identification information included in the paging signal. The target terminal 200 then determines whether the identification information analyzed in step 540 matches the unique number assigned to the target terminal 200.

If the identification information from the received paging signal and the unique number assigned to the target terminal 200 coincide with each other, the target terminal 200 transmits the access signal in response to the paging signal in step 550. In this case, in response to a call request for the location service request from the tracking terminal 210, a separate call path is connected to the call, and the target terminal 200 transmits only an access signal for the paging signal.

In accordance with the transmission of the access signal, the base station controller 100 identifies a communication resource that manages the current communication area where the target terminal 200 is located. The communication resource means a plurality of base stations that manage a given service area by dividing the service area into a plurality of cells.

In detail, the base station controller 100 uses at least three base stations around the target terminal to receive an access signal from the target terminal 200 in step 560. The location of the target terminal is confirmed by a signal from the base station located in the cell. Then, the base station controller 100 transmits the location confirmation result, that is, location information of the target terminal 200 to the tracking terminal 210.

In response, the tracking terminal 210 receives the location information of the target terminal 200 transmitted from the base station controller 100 via the base station and displays the location information in step 580. In this case, the location information of the guardian may be provided through a text or voice according to the type of the tracking terminal 210 or may be provided in a map form. That is, the location information of the target terminal 200 worn by the guardian may be expressed and provided in various ways.

Meanwhile, the positioning service according to the present invention uses an access signal from a target terminal in response to a paging signal received from a base station and a received paging signal according to a request for a positioning service from a tracking terminal. Same as

First, the reason for using the paging signal and the access signal is that the purpose is to determine the location of the protector wearing the target terminal, not the actual call connection between the guardian and the guardian. Therefore, the waste of communication resources due to the continuous management of the location information of the mobile communication terminal using, for example, a home location register (HLR) of a conventional mobile communication network is prevented. In particular, the present invention provides a location where a guardian is located in response to a request for location service from a guardian without the need to continuously transmit and receive location information in a limited area such as an amusement park, for example, when it is not necessary to continuously use the location service for several tens of hours. It will provide the location information of the communication area.

As described above, the present invention prevents the occurrence of a lost child in a specific service area such as an amusement park, for example, through a target terminal that enables the location of the protected person using a mobile communication network. It is effective to track the location of the lost child to find the lost child. In addition, the present invention is to enable the location tracking by implementing the function at a low cost without expensive GPS equipment that calculates and confirms the location using an artificial satellite, the current state of the guardian holding the target terminal through the tracking terminal carried by the guardian This has the advantage of making it easy to identify the location.
