The location tracking-based information provision system according to the present invention can achieve the following effects.

In the present invention, in addition to GPS location information, the current location of the terminal is tracked using the collectible locations of Wi-Fi terminals around the terminal and location information of telecommunication company repeaters. In detail, the current location of the terminal is tracked by collecting the GPS location, nearby Wi-Fi terminal location, and telecommunication company repeater location information collected just before entering a location where GPS reception is not possible.

Therefore, even when GPS reception is not possible, the current location of the terminal can be tracked and necessary location-based information can be provided to the terminal user.

In addition, in the present invention, the location of the terminal is tracked only when the collected latest GPS location, Wi-Fi terminal location, and telecommunication company repeater location are within a certain radius. If any one of the GPS location, Wi-Fi terminal location, and telecommunication company repeater location is outside a certain radius, the remaining two location information are used to collect the nearest additional Wi-Fi terminal location or telecommunication company repeater location to determine the current location of the terminal. track.

Referring to Figure 1, the location tracking-based information provision system of the present invention includes a terminal 100 that collects location information and transmits it to the server 200, and a terminal (100) using the location information transmitted from the terminal 100. It may include a server 200 that tracks the location of 100).

The terminal 100 generally refers to a wireless communication terminal carried by an individual, and may be a tablet PC, laptop, etc. in addition to a smartphone.

The terminal 100 collects location information including GPS location, Wi-Fi terminal location, and telecommunication company repeater location and transmits it to the server 200.

Here, the GPS location is real-time or most recent GPS location information collected through a GPS receiver, and the Wi-Fi terminal location is location information of a terminal to which the terminal 100 is currently connected.

And the location of the communication company repeater is location information of the communication company repeater to which the terminal 100 is connected to receive wireless communication data. This repeater location information may use information collected by a location-based service providing application installed on the terminal 100.

The location information may be stored in the data storage space of the terminal 100 and then transmitted to the server 200 when tracking the location of the terminal 100 is required. For example, transmitted when a dedicated application for providing location-based information according to the present invention is executed, or when a request for location tracking or information provision is input through the terminal 100 after execution of the dedicated application. It can be.

Additionally, the server 200 is connected to the terminal 100 through network communication and tracks the location of the terminal 100 using the location information transmitted from the terminal 100. And the server 200 provides information on nearby stores to the terminal 100 based on the tracked current location of the terminal 100.

Referring to FIG. 1, the server 200 includes a location tracking unit 210 that tracks the location of the terminal, a map database unit 220 that stores map data, a store database unit 230 that stores offline store information, and the A map marker generator 240 that generates a plurality of markers to provide information on nearby stores based on the location tracking results of the terminal 100, and a pop-up window on the map displaying information corresponding to the marker selected through the terminal 100. It includes a detailed information provision unit 250 provided through .

The location tracking unit 210 tracks the current location of the terminal 100 using location information transmitted from the terminal 100.

In addition, the store database unit 230 stores location information, seller information, product sales information, and sales product category information of offline stores. The store database unit 230 classifies and stores information received through a separate information registration terminal 300 into each category.

Next, the map marker generator 240 creates the current location marker of the terminal and the current location of the terminal on the map provided through the map database unit 220 based on the terminal current location tracking result of the location tracking unit 210. Create multiple store markers to provide seller information and product sales information of stores around the location.

Figure 2 is a flowchart showing the location tracking process of the location tracking-based information provision system according to an embodiment of the present invention, and Figures 3 to 6 are conceptual diagrams for explaining the current location tracking process of the terminal according to an embodiment of the present invention. am.

Hereinafter, the location tracking process of the server 200 will be described in detail with reference to FIGS. 2 to 6.

First, if GPS reception is possible in the terminal 100, the server 200 determines the current GPS location information transmitted from the terminal 100 as the current location of the terminal and provides information on nearby stores.

On the other hand, when GPS reception is not possible in the terminal 100, the server 200 tracks the current location of the terminal through location information transmitted from the terminal 100.

Tracking the current location of the terminal of the server 200 is performed by the location tracking unit 210.

Referring to FIG. 2, in the process of tracking the current location of the terminal, first, location information transmitted from the terminal 100 along with a request for tracking the location of the terminal 100 is input (S110).

Next, the location tracking unit 210 selects three types of location information in order of priority: the Wi-Fi terminal location, the telecommunication company repeater location, and the most recently collected GPS location from the location information transmitted from the terminal 100. The first reference coordinate is extracted by extracting the first coordinate (P1), the second coordinate (P2), and the third coordinate (P3) (S120).

Here, the first coordinate (P1), the second coordinate (P2), and the third coordinate (P3) are used as reference coordinates for tracking the current location of the terminal.

In order to extract the three first reference coordinates (S120), the Wi-Fi terminal location information is first checked.

The Wi-Fi terminal location information exists when the terminal 100 is currently connected to a Wi-Fi terminal. Therefore, if the Wi-Fi terminal location information is input, the Wi-Fi terminal location information is selected as the first priority.

Next, check the location information of the telecommunication company repeater.

The telecommunication company repeater location information may be collected according to the number of other location-based service providing applications installed on the terminal 100. For example, if there are three location-based service providing applications installed on the terminal 100, location information of three telecommunication carrier repeaters may be collected. Therefore, if the telecommunication company repeater location information is input, the telecommunication company repeater location information is selected as the second priority.

Next, check the most recently collected GPS location information.

If three coordinates to be used as the first reference coordinates are not extracted from the Wi-Fi terminal location information and the communication company repeater location information, the most recently collected GPS location information is selected as the third priority.

That is, if the location information transmitted from the terminal 100 includes one Wi-Fi terminal location, one communication company repeater location, and one most recently collected GPS location, each location information is divided into first coordinates (P1) and second coordinates ( P2) and third coordinates (P3) can be extracted.

However, if the terminal 100 is not currently connected to the Wi-Fi terminal, the Wi-Fi terminal location information is not confirmed. At this time, the next priority one or two locations of the telecommunication company repeater and the most recently collected GPS location can be extracted as the first coordinates (P1), second coordinates (P2), and third coordinates (P3). .

Meanwhile, the telecommunication company repeater location information may also be selected according to priority. Specifically, as the telecommunication company repeater location information is preset in the location tracking unit 210, the information can be selected according to the priority of other location-based service providing applications. In other words, the selection order of which application's information is to be selected first among the many location-based service providing applications that can be installed on the terminal 100 is set in advance.

If all three coordinates are extracted in the first reference coordinate extraction process (S120), the first radius (r) centered on each of the first coordinate (P1), second coordinate (P2), and third coordinate (P3) ) Create (S130) three reference circles (C1, C2, C3). At this time, the reference circles (C1, C2, C3) are created with the same first radius (r), and the radius is most preferably in the range of 1 to 2 km.

As shown in FIG. 3, when the areas of the three reference circles (C1, C2, C3) generated in the reference circle creation process (S130) all intersect, the first coordinate (P1) and the second coordinate ( The center coordinate (CP) of the triangle formed by P2) and the third coordinate (P3) is extracted (S140) and determined as the current location of the terminal (S150).

Here, the extraction of the center coordinates (CP) uses triangulation. At this time, the reference coordinates are substituted into the triangular points, which are fixed indicators of triangulation, and the distance between the center coordinates to be tracked and each triangular point is obtained by substituting the first radius, which is the same distance.

That is, the first radius is substituted for the distance instead of the distance estimated through the reception strength of the communication signal. Therefore, in the present invention, the location can be tracked even if different fixed indicators are used, such as the location of the Wi-Fi terminal and the location of the telecommunication company repeater.

However, since the terminal 100 is not currently connected to a Wi-Fi terminal, there is no Wi-Fi terminal location information, and the number of installations of other location-based service providing applications is insufficient or the connection is unstable, so the number of collected location information of the telecommunication company repeater is insufficient. In this case, it becomes impossible to extract three reference coordinates in the first reference coordinate extraction process (S120).

In this case, if two reference coordinates are extracted in the first reference coordinate extraction process (S120), the current location of the terminal can be tracked using the two extracted reference coordinates.

First, two reference circles of a first radius r centered on each of the two coordinates extracted in the first reference coordinate extraction process (S120) are created (S131). At this time, the reference circles are also created with the same first radius (r).

As shown in (a) of FIG. 4, when the areas of the two reference circles (C2, C3) generated in the reference circle creation process (S131) intersect each other, the areas of the two reference circles (C2, C3) Secondary reference coordinates are extracted by extracting the two intersection points as fourth coordinates (P4) and fifth coordinates (P5), respectively (S133).

Next, the location of the Wi-Fi terminal or telecommunication company repeater closest to one of the fourth coordinates (P4) and the fifth coordinates (P5) is searched and extracted as the sixth coordinate (P6) (S134).

Then, as shown in FIG. 5, the center coordinate (CP) of the triangle formed by the fourth coordinate (P4), the fifth coordinate (P5), and the sixth coordinate (P6) is extracted (S135) to determine the current location of the terminal. It is judged (S150).

However, if less than one coordinate is extracted in the first reference coordinate extraction process (S120), location tracking is determined to have failed (S160) and tracking of the terminal's current location is terminated.

Meanwhile, if any one of the most recently collected GPS location, Wi-Fi terminal location, and telecommunication company repeater location is far away from the other two locations, the three references generated in the three reference circle creation process (S130) The areas of the circles (C1, C2, C3) do not all intersect.

That is, two reference circles among the areas of the reference circles (C1, C2, C3) of the first radius (r) centered on the first coordinate (P1), the second coordinate (P2), and the third coordinate (P3) There are cases where the areas of the reference circles (C1, C2, C3) do not intersect at all.

Even in this case, the current location of the terminal can be tracked by extracting two reference coordinates.

As shown in (b) of FIG. 4, after the three reference circles creation process (S130), two of the areas of the three reference circles (C1, C2, C3) created with the first radius (r) When only the reference circles (C2, C3) intersect, the secondary reference coordinate extraction process extracts the two intersection points of the two reference circles (C2, C3) as the fourth coordinate (P4) and the fifth coordinate (P5), respectively. (S133) is performed, and then the sixth coordinate (P6) is extracted (S134), and the center coordinate (CP) of the triangle formed by the fourth coordinate (P4), the fifth coordinate (P5), and the sixth coordinate (P6) is performed. ) is extracted (S135) and determined as the current location of the terminal (S150).

However, there are cases where the areas of the three reference circles (C1, C2, C3) created in the three reference circle creation process (S130) do not intersect at all.

In this case, the position tracking unit 210 moves a certain radius from the first radius r until two of the three reference circles C1, C2, and C3 intersect, as shown in FIG. 6. The expansion process (S132) is performed step by step (α).

Here, the expansion radius (α) is most preferably in the range of 50 to 200 m. That is, 50n to 200n are added to the first radius (r). (n=number of radius expansions)

And, when two reference circles (C2', C3') of extended radii intersect, the two intersection points of the two reference circles (C2', C3') are assigned to the fourth coordinate (P4) and the fifth coordinate, respectively. A secondary reference coordinate extraction process (S133) is performed by extracting (P5), and then the sixth coordinate is extracted (S134), and the fourth coordinate (P4), the fifth coordinate (P5), and the sixth coordinate (P6) are performed. ) is extracted (S135) and determined as the current location of the terminal (S150).

Figure 7 is a flowchart showing the information provision procedure of the location tracking-based information provision system according to an embodiment of the present invention.

Referring to FIG. 7, the provision of information by the location tracking-based information provision system of the present invention begins with execution (S210) of the application for providing location tracking-based information according to the present invention.

First, the terminal 100 requests the server 200 to provide information on nearby stores (S220).

If GPS reception is possible in the terminal 100, the server 200 displays the current location marker of the terminal 100 on the map provided through the map database unit 220, as well as stores near the current location of the terminal. After creating a plurality of store markers to provide information (S310), the map is transmitted to the terminal 100 (S320).

At this time, the current location of the terminal is the GPS coordinates determined by the GPS receiver of the terminal 100.

And when GPS reception is not possible in the terminal 100, the terminal 100 collects location information (S230) and then transmits the collected location information to the server 200 and requests location tracking (S240). .

Next, the location tracking unit 210 of the server 200 extracts the most recently collected GPS location, Wi-Fi terminal location, and telecommunication company repeater location from the location information transmitted from the terminal 100 and tracks the current location of the terminal. (S330). Afterwards, a terminal current location marker and a store marker are created (S310), and then the map is transmitted to the terminal 100 (S320).

Meanwhile, when a user inputs a product of interest into the terminal 100, the map marker generator 240 of the server 200 creates an emphasis marker to provide information on a store selling the product of interest (S311). At this time, the highlight marker is expressed in a different color, shape, or size that is distinct from the store marker.

Then, when the user selects a specific store marker on the map in the terminal 100, the detailed information provider 250 of the server 200 creates a pop-up window showing information about the store and displays it on the map (S312). , information is provided by transmitting the map to the terminal 100 (S320).

The map transmitted from the server 200 to the terminal 100 contains various information based on tracking the current location of various terminals, and this map is displayed on the application execution screen of the terminal 100 (S250).
