Description

Location verification service using location information and geographic information {POSITION CONVICTION SERVICE METHOD USING POSITION AND GEOGRAPHIC INFORMATION}

The present invention relates to a location service method using location information and geographic information, and to a computer readable recording medium storing a program for realizing the method. A location service method using location information and geographic information for linking location information and geographic information technology in conjunction with an information retrieval system, and a computer-readable recording medium recording a program for realizing the method.

The present invention provides location information on a terminal provided by various methods in a wireless communication system and various additional services using the same. In general, there are several ways to check the location.

First, the network-based technology is a method of measuring the position using a base station constituting a wireless communication network. The parameters required are angle of arrival (AOA) and time of arrival (TOA). , Time difference of arrival (TDOA), amplitude, phase, and signal strength. The calculation of the location of these parameters on the network side is called network-based technology, and the parameters are classified into a method of receiving at the base station and a method of receiving at the terminal and delivering them to the network side. In the case of using the network-based technology, it is possible to check the location without putting a load on the terminal without any equipment. The Federal Communications Commission (FCC) of the United States requires all wireless carriers to provide E911 (Enhanced 911) service, which allows 67 percent reliability and 125 meters of error by October 2001.

Second, the dedicated network-based technology uses a different frequency from the dedicated network for positioning and the general wireless communication system. An example is the use of a dedicated network in the US location and monitoring (LMS) band. This is a kind of road sign, and it can be said that the roadside base station of the Intelligent Transportation System (ITS) is included in this category. Dedicated network-based technology generally lacks economic feasibility because a separate network must be constructed for location verification. Signals can also be designed separately for specific applications and achieve high accuracy in some locations.

Third, the terminal-based technology may also be referred to as a technology based on a global positioning system (GPS). A method of identifying one's own location by using signal information from a GPS satellite, a method in which a GPS receiver only announces its own location, and a terminal capable of communicating with a GPS receiver (eg, a TRS (Trunked Radio System), cellular For example, there is a method of connecting a personal communication system (PCS) terminal to transmit a location information service to a control center that manages a location of its own location identified by a GPS receiver.

Recently, a method of using a terminal incorporating a GPS part in a mobile communication terminal has also been proposed. However, in case of using the built-in GPS, it is impossible to use a conventional terminal, so a new terminal must be purchased, and since the power consumption is accompanied by GPS signal processing, the accuracy of the GPS satellite signal cannot be received. On the other hand, when using an external GPS, the GPS must be purchased separately, which is expensive and the size of the terminal is large, making it inconvenient to carry.

Fourth, radio camera technology is a method of finding a location by comparing a fingerprint of a wireless signal form of a current user with a wireless signal form known in advance for a specific region. The technology uses a database of user signals received via multipath and radio signal propagation that is already established to enable continuous location measurements regardless of the user's own location requirements. It takes a lot of money to build a database for the wireless signal, and has a disadvantage in that a lot of costs are used to maintain because the database needs to be newly updated when the environment changes.

Finally, there is a method of identifying the location by the ID (Identifier) of the base station or the sector in the base station area without using a special positioning technology. There are low power base station by using the radius of the base station 100 to the ^{CT-2 (Cordless Telephone 2 nd} Generation) approximately 200m. In the case of CT-2, its location can be confirmed by the ID of the receiving base station. In addition, it is possible to identify its own location by a sector ID in a base station or a base station area that is being served by a digital cellular mobile communication system or a PCS system. In a cellular mobile communication system or a PCS, the size of a sector in a base station or a base station area varies, so the accuracy of the position varies greatly.

The present invention is a method of identifying the location of a mobile terminal using the above-described positioning technology and using the information to combine location information and Geographic Information System (GIS) technology in conjunction with a geographic information retrieval system. Accordingly, the present invention is to provide a variety of additional services such as spatial location, related geographic information, etc. as well as location information by recognizing the available form of the mobile terminal and using voice, text, web browsing, and application download technology.

Currently, a commercially available location identification technology includes a technology of combining a GPS (Global Positioning System) for positioning and a cellular system and a PCS terminal, and a technology of identifying a location by a base station ID.

In the former case, a GPS receiver needs to be additionally purchased and installed in addition to the conventional mobile communication terminal, and it is often used in a vehicle mounted form because the terminal is large and inconvenient to carry. The error is also very large in areas where GPS signals cannot be received.

On the other hand, the latter case is a technology that uses the base station ID has a disadvantage that the accuracy of the location is not constant because the radius of the base station is changed from hundreds of meters to several km, tracking the vehicle that can provide service even in the error of hundreds of meters The disadvantage is that some services are limited. However, as the technology advances, this margin of error will continue to shrink, and for today's end users, a margin of error of 100-200 meters is not a big problem. In addition, in the case of a wired line, a service for informing a location of a corresponding area is provided when a part of a desired location is to be entered, but it does not provide a current location.

Therefore, the present invention provides a technology that can provide a variety of additional services, such as location information, spatial location and related geographic information to be able to check the location of their own without providing additional devices to the modern man who is essentially using a mobile terminal Is required.

The present invention has been proposed to solve the above problems, the location information and geography for combining the location information and geographic information technology to identify the location of the terminal using the location identification technology and in conjunction with the geographic information search system It is an object of the present invention to provide a positioning service method using information and a computer-readable recording medium recording a program for realizing the method.

In addition, the present invention, by providing a variety of additional services including location information, spatial location and related geographic information without installing additional devices in the user terminal, location for providing a variety of information to the mobile users It is an object of the present invention to provide a computer-readable recording medium recording a verification service method and a program for realizing the method.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a wireless communication system to which the present invention is applied.

As shown in FIG. 1, when information such as the location of a mobile terminal or a similar device, a terminal type, a terminal unique identification ID, and the like are transmitted to the base station 12 using various positioning techniques, the base station 12 may transmit the information to the base station 12. Can be identified. Therefore, this information is transmitted to the location information system 16 via the base station controller 14 and the communication network.

Here, the location information system 16 searches the map of the corresponding area in the geographic information retrieval system database 17 through the location information of the terminal, and retrieves information on a representative place name or a specific building.

2 is a flowchart illustrating an embodiment of a location service method in a wireless communication system according to the present invention.

As shown in FIG. 2, in order to confirm the location, the location information and the terminal information are extracted (201), and the extracted information is transmitted to the geographic information search system (202).

Subsequently, in the database of the geographic information retrieval system through the location information of the terminal, after searching for the map leaf for the corresponding area (203), it is determined whether the searched area is a service providing area (204).

As a result of the determination, if it is not the service providing region, the announcement or text information is transmitted (205). If the service providing region is analyzed (206), the terminal type is analyzed, and it is determined whether the terminal transmits voice and text (207).

As a result, if the terminal transmits voice and text, the specific region extraction and text are converted into voice messages (208) and then converted into text messages to send information to the terminal (214). Check whether the terminal for the web (209).

As a result, the web terminal extracts a specific region and converts the web (210), and then sends information to the terminal (214). If it is not the web terminal, it is checked whether the program download function terminal (211).

As a result of the check, if it is not the download function terminal, the process proceeds to step 206 of analyzing the terminal type, and if the download function terminal is downloaded (212).

Subsequently, geographic information for a specific region is extracted (213). At this time, an appropriate map is extracted by using the transmitted location information and boundary information of each map constructed in a database of a geographic information retrieval system (GIS DB). It extracts information about the desired administrative place or specific building from various database management systems (DBMS) linked with the location information. Also, depending on the type of terminal, this information downloads the map directly when voice, text, web or application is downloaded.

Meanwhile, after transmitting the information to the terminal (214), it is checked whether there is a request for additional information (215).

As a result of the check, if an additional service is generated (216), the process proceeds to step 214 of sending information to the terminal. If not, the service is terminated. In this case, the user who has confirmed the location through the mobile terminal in order to provide the additional service may obtain application information therefrom. As a result, ARS, text messages, web browsing, or application functions can be used to obtain desired information.

In the present invention, a mobile communication terminal such as a voice and text terminal, a web terminal and a program download function terminal is a terminal capable of simply receiving text information and web browsing from a terminal capable of voice communication, and separately connected with a computer. Or, there are various types of terminals, ranging from intelligent terminals that can be driven by downloading application programs on the terminals themselves.

First, a terminal capable of transmitting only voice and text information is a basic mobile terminal. The GQS (GIS Query System) searches for a corresponding map from the transmitted location coordinates and provides information that is easy for the user to recognize, such as the nearest specific building name or administrative place name. Convert the voice and text message information to the user. Users can also use the ARS (Audio Response System) and the text message transmission function to further check the desired information.

Second, a web browsing capable terminal can obtain more information by using a web browsing function instead of voice or text information. In other words, you can get not only your location but also the distance, direction, phone number, etc. from the area to a particular restaurant or area you are looking for.

Third, terminals capable of interworking with computers or downloading application programs will be provided in next generation wireless communication services such as IMT-2000. It basically provides a video service, so you can download applets such as Java from GQS. Therefore, if data communication is possible in the conventional terminal, the applet can be downloaded using a portable PC or the like. In addition, since the mobile terminal itself may be equipped with a map search program in advance, GQS checks the user's location, downloads the map search program to the user terminal, searches the corresponding map, and moves the map according to the user's input. Or, it performs a query function related to the shortest path to the desired area and other geographic information systems (GIS). Since this method uses a single download, it does not incur additional communication costs for the user's map operation such as zooming and panning.

3A and 3B are flowcharts illustrating an embodiment of a location service method in a terminal according to the present invention.

As shown in FIG. 3, an intelligent terminal (a terminal capable of computing and having a built-in memory) may download an application program capable of operating geographic information from a geographic information retrieval system and perform a program independently. Even if these programs are built in, they can be executed.

First, after receiving data from the system (301), the type of the received data is determined (302).

As a result of the determination, if the data is for downloading the application, the position and the corresponding leaf are received (303).

At this time, it is checked whether the user performs a function such as zooming, panning, etc. using this information.

As a result of the check, it is searched whether the range of the leaves is out (305).

As a result of the search, if a departure is made, the process proceeds to the process of receiving the location and the corresponding leaf (303). If the departure is not performed, the leaf is displayed (306) and the program is operated (307) to check whether zooming or panning is performed. Proceed to step 304 of the process.

As a result of the check, it is determined whether or not to search for a specific region or place name if not performed (308).

As a result of the determination, if a search is requested, the process proceeds to step 302 of requesting search data and receiving a location and a corresponding map leaf.

As a result of determination, if there is no search, it is checked whether there is a request for additional information (310).

As a result of the check, after performing the additional service (311) if there is a request, it is determined whether or not to terminate the service (312), and if no request goes to the process (312) to determine whether to terminate the service.

If it is determined that the service is not terminated, the process proceeds to step 301 of receiving data from the system.

On the other hand, as a result of determining the type of the received data, if the web browsing is displayed on the LCD (Liquid Crystal Display) (313), if the voice message to send the message through the speaker, if the text message is displayed on the LCD (314) In step 310, the method of the present invention as described above is implemented as a program and can be read by a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical). Disk, etc.).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, the present invention has the effect of confirming the location of the mobile terminal through the location checking technology and combining the location information and the geographic information technology in conjunction with the geographic information search system to provide a more improved service.

In addition, it is possible to provide location information, spatial location and related geographic information without adding a separate device to the wireless communication system. There is an effect that can provide a variety of information.
