In addition, a control terminal having a control right among the group terminals 10 may control a screen of another group terminal 10 by transmitting a control message. That is, when the control terminal user inputs a control message using his control terminal, the corresponding message is transmitted as another group message so that the other group terminal 10 user can see the same screen as the user. Detailed description thereof will be described later.

The location information sharing server 30 maps location information received from each group terminal 10 to a map so that users of each group terminal 10 can share respective location information. Perform the functions provided to Here, the location information sharing server 30 may provide a map only for the first time and only provide location information of each group terminal 10 thereafter. Therefore, the group terminal 10 maps the location information received from the location information sharing server 30 with the map received first, and displays the updated location information on the map. Hereinafter, a service that can be shared by each group terminal 10 will be referred to as a "location information sharing service".

Also, the location information sharing server 30 transmits data corresponding to the control message to the corresponding group terminal 10 in response to the control message received from the control terminal. For example, when a user of a control terminal writes a control message such as a route or a specific location display using a touch screen function on a map displayed on a screen of the control terminal, the control terminal generates vector information about the control terminal and generates other information. A request is made to transmit to one of the group terminals 10, and the location information sharing server 30 receiving the received information transmits the vector information or the map including the vector information to the corresponding group terminal 10. Therefore, the group terminal 10 receiving the same may output the same screen that is output on the screen of the control terminal.

Therefore, the user of the group terminal 10 can check the route to the target site at any time even if the target site is moved. In addition, when a plurality of target destinations are set from the control terminal, each path to each target destination is searched and provided to the corresponding group terminal 10.

In addition, the location information sharing server 30 provides a function of providing a path to the target terminal corresponding to the current time or the current location of the group terminal 10 to the corresponding group terminal 10 according to the scheduling received from the control terminal. To perform. For example, when receiving the scheduled data in the order of position A (10 o'clock), B (11 o'clock), and C (12 o'clock) from the control terminal, all the group terminals 10 or the control terminals are received. The group terminal 10 is set to provide a route to A at 10 o'clock, a route to B at 11 o'clock, and a route to C at 12 o'clock. That is, the scheduling data includes time information and location information (target location information). Of course, it may further include a message corresponding to each time information. For example, at 12 o'clock, the location C is set and the message &quot; Meet here to eat &quot; is stored together, and at 12 o'clock, the route to the C location is provided to the group terminal 10 together with the message. .

Here, the entire system may further include a wireless communication network (not shown) such as a mobile communication network for performing data communication between the group terminal 10 and the location information sharing server 30. That is, each group terminal 10 and the location information sharing server 30 are assigned an IP address, thereby performing wireless data communication.

In another embodiment, RF (Radio Frequency) communication between the group terminal 10 and the location information sharing server 30 is performed without the need for a wireless communication network. That is, by performing data communication using a specific frequency in a narrow space such as an amusement park or a specific travel destination, it is possible to provide an effect that charging is not generated due to communication using a mobile communication network.

In another embodiment, only when the initial service request is performed, the location information sharing server 30 is connected to the location information sharing server 30 using a wireless communication network, and data communication according to service execution thereafter is to perform RF communication. That is, the group terminal 10 connects to the server using the URL of the location information sharing server 30, and then sets the communication frequency in accordance with automatic or user operation. Therefore, transmission and reception of data can be performed later through RF communication.

Hereinafter, a configuration according to the function of the location information sharing server 30 will be described with reference to the drawings.

It may include.

Referring again to FIG. 2A, the route search unit 34 performs a function of searching for a movement route between the target land set by the control terminal and the group terminal 10. That is, the optimal route is calculated using the location information of the target site and the location information of the group terminal 10. In this case, the search for the movement route according to the present invention is performed every predetermined time (for example, 10 seconds) or when a target is a moving object (for example, a control terminal or a specific group terminal) or a request from the group terminal 10. If there is, re-search the path and provide it. Since the path search unit 34 may frequently change the moving path according to the moving object, it is preferable to acquire and re-search the target location and the position information of the corresponding group terminal 10 every predetermined time.

In addition, when there are a plurality of target destinations, the path search unit 34 searches all the moving paths to each target destination. Accordingly, the group terminal 10 receiving the same can check each path to the plurality of target destinations, and can easily move to the desired target destination.

The web page providing unit 35 performs a function of providing a web page for a user interface when the group terminal 10 accesses the location information sharing server 30. Therefore, the user of the group terminal 10 can conveniently perform service setting such as setting information on each group terminal to be provided with the service when the location information sharing service request is made.

The user authentication unit 36 may verify whether the user of each group terminal 10 requesting the service is a registered user, or whether the group terminal 10 is a service-enabled group terminal 10 such as whether wireless data communication is possible. Performs a function to authenticate whether or not.

The control unit 37 performs a function of controlling the operation of each component of the above-described location information sharing server 30, and in particular, the map management unit (10) maps a map corresponding to at least one of the location information received from each group terminal (10). 32 to perform the function of mapping the location information of each group terminal (10).

That is, it is determined whether the search for the movement route is necessary, whether the control message should be transmitted together with the map, and the corresponding information is generated.

In addition, when there is scheduling data transmitted from the control terminal, the controller 37 controls the path search unit 34 to search the corresponding path with reference to the scheduling data.

In addition, the control unit 37 performs a function of setting a control terminal having a control right in response to a message according to the control right setting change received from the control terminal.

Hereinafter, a procedure of a location information sharing service according to the present invention will be described in detail with reference to the drawings.

3 is a diagram illustrating a process of providing a location information sharing service according to an exemplary embodiment of the present invention.

Hereinafter, for convenience of description, a case in which three group terminals 10 including a control terminal will be described as an example, but two or more group terminals 10 may be equally applied. Will be self-evident.

According to FIG. 3, in step 310, the location information sharing server 30 receives a location information sharing service request including location information and group identification information of a corresponding group terminal from one group terminal 1 11 of a plurality of group terminals. do. Here, the group terminal 1 (11) requesting the location information sharing service may be set as the first control terminal. In another embodiment, when the location information sharing service request, information on the control right (information on which group terminal is the control terminal) may be transmitted. Therefore, the location information sharing server 30 may recognize the control terminal using the information on the control right. Hereinafter, the setting of the group terminal 1 (11) applying for the initial location information sharing service as a control terminal will be described as an example.

The group identification information is information that can be recognized by the location information sharing server 30 for the group terminal 2 (12) and the group terminal 3 (13). At least one of an IP address, a serial number, an ID, and a phone number may be used. In addition, it is natural that unique information for identifying a group terminal performing wireless data communication may be equally applied.

In step 320, the location information sharing server 30 recognizes the group terminal 2 (12) and the group terminal 3 (13) using the group identification information. That is, the IP address for data communication with the group terminal 2 (12) and the group terminal 3 (13) is recognized. Here, the authentication procedure for the recognized group terminal may be performed. That is, after determining whether the terminal is available for service or a terminal capable of performing data communication, and if the terminal is not available for service or cannot perform data communication, an error message for this is returned to the group terminal 1 (11). To the control terminal.

In operation 330, the location information sharing server 30 requests location information from the group terminal 2 12 and the group terminal 3 13. In step 340, the group terminals 2, 3 (12, 13) measure the location coordinates using the GPS receiving module and transmit the current location to the location information sharing server 30 in step 345.

In operation 350, the location information sharing server 30 extracts a map corresponding to at least one of the location information received from the control terminal and the group terminals 2, 3 (12, 13), and maps the location information to the extracted map.

In step 360, the location information sharing server 30 transmits a map to which location information of each group terminal is mapped to the group terminals 1, 2, 3 (11, 12, 13). Here, the map transmitted to each group terminal may not include its location information. For example, location information of the group terminal 1 11 is not mapped on the map provided to the group terminal 1 11. Therefore, when each group terminal receives the map from the location information sharing server 30, the group terminal measures the current location information and maps it with the map.

In step 370, each of the group terminals 11, 12, and 13 outputs a map. Therefore, the user of each group terminal (11, 12, 13) can check the position of the other group terminal.

Thereafter, the location information sharing server 30 may receive location information of each group terminal 11, 12, 13 from time to time, and provide location information of another group terminal to each group terminal 11, 12, 13. have. Therefore, users of each of the group terminals 11, 12, and 13 can check the changed positions of other group terminals including themselves from time to time.

4 is a flowchart illustrating a process of processing a control message of a control terminal according to an exemplary embodiment of the present invention.

According to FIG. 4, in step 410, the location information sharing server 30 receives a control message from the control terminal 15. Here, the control message will be described by taking a route search provision request targeting the control terminal 15 as an example. The user of the control terminal 15 transmits the message to the location providing server with the message "Please come to my location" so that the user of another group terminal can come to his location. In addition, although the control message may be transmitted to all other group terminals, the control message may be individually transmitted to other group terminals according to the user's selection of the control terminal 15. That is, the user of the control terminal 15 may select another group terminal to transmit the control message. In the present embodiment, the transmission of the control message to the group terminal 2 (12) will be described as an example.

Accordingly, in step 420, the location information sharing server 30 searches for a path between the target location and the group terminal 2 (12). Here, the method may include requesting and receiving location information of the group terminal 2 12 from the group terminal 2 12. That is, in order to search for a more accurate path, location information on the current location of the group terminal 2 (12) is received from the group terminal 2 (12), and the path is searched accordingly. As described above, when there are a plurality of target destinations, respective paths between each target destination and the group terminal 2 (12) are searched for.

In step 430, the location information sharing server 30 transmits the searched route and the message "Come to my location" received from the control terminal 15 to the group terminal 2 (12). Here, the route may be provided including a map, or only the vector information of the route may be provided. In the case of providing only the vector information, the group terminal 2 (12) receiving the information directly maps the route to the map.

In step 440, the group terminal 2 (12) outputs the received path and message.

Thereafter, at a predetermined time interval or at the request of the group terminal 2 (12), in step 450, the position information of the target destination (control terminal 15) and the position information of the group terminal 2 (12) are acquired and the route is searched again. Here, of course, if the target destination is a stationary object instead of a moving object, it is natural that the position information of the target destination does not need to be acquired separately.

In step 460, the location information sharing server 30 transmits the re-discovered path to the group terminal 2 12, and in step 470, the group terminal outputs the received path. Steps 450 through 470 are repeated until the group terminal arrives at the destination. That is, the location information sharing server 30 determines whether the location information of the target location and the location information of the group terminal 2 12 match or are similar within a preset range, and re-search and provide a path according to the determined result. do.

5 is a diagram illustrating a processing procedure according to a control right request from an arbitrary group terminal according to an exemplary embodiment of the present invention.

According to FIG. 5, in step 510, the location information sharing server 30 receives a control right request from the group terminal 2 12. Accordingly, in step 520, the location information sharing server 30 informs the control terminal 15 of the preset information about the control right request from the group terminal 2 (12).

In operation 530, the user of the control terminal 15 determines to provide the control right. If the control authority is accepted according to the user input, in operation 540, the control terminal 15 transmits the acceptance message to the location information sharing server 30.

In step 550, the location information sharing server 30 sets the group terminal 2 (12) as a new control terminal 15 and stores the contents thereof. In step 560, the position information sharing server 30 sets the group terminal 2 (12) as a new control terminal 15. Inform. Therefore, the group terminal 2 (12) from now on becomes a new control terminal 15 can generate a control message and transmit to the location information sharing server 30.

If the control right is not granted in step 530 described above, it is notified that the control right is not obtained to the group terminal 2 12 in steps 570 to 580.

6A and 6B illustrate a user interface (UI) screen in which location information is shared and displayed in each group terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 6A, reference numeral 610 illustrates output on a screen of a control terminal according to a location information sharing service. As shown in 610, the locations of the group terminals are displayed on a map of a specific region. The map is output identically in each group terminal.

Below the map, it shows who each terminal is. Of course, the name may appear on the map instead of A, B or C. The name displayed on the screen may be stored in an address book or the like to be input separately from a user so as to correspond to each group terminal identification information (for example, a phone number, IP address, etc.), or one of the group terminals (for example, It is received in advance from the control terminal and stored in the location information sharing server 30, it may be received from the location information sharing server 30.

As shown in the figure, the check mark beside A indicates that the terminal A group currently has control.

Referring to reference numeral 630, the control terminal user clicks B on the map to create a control message to be sent to the group terminal B. FIG. That is, when B on the map is clicked, a message window for inputting a message is outputted (a telephone connection is also possible), and a message is inputted. The user of the control terminal uses the electronic pen 631 on the map as shown at 630. You can draw an arrow using the back. The control message including the input message and the vector data according to the arrow is transmitted to the group terminal corresponding to B via the location information sharing server 30, so that the group terminal user who receives it receives the same screen as the reference numeral 630. It becomes possible.

6B, when the control terminal user sets A as a target and transmits a control message to the group terminal B, as shown by reference numeral 650, the location information sharing server 30 is the target terminal at the group terminal B. The route to (group terminal A) is searched and provided to group terminal B.

Receiving this, the group terminal B outputs a screen like reference number 670. Therefore, the user of the group terminal B can know the route to the group terminal A which is the target place.

Then, after a predetermined time or at the request of the group terminal B, the location information sharing server 30 re-searches the path between the target place and the group terminal B and provides the group terminal B. Therefore, the group terminal B outputs a screen like reference numeral 690.

FIG. 7 is a diagram illustrating a user interface (UI) screen displaying each moving path from a group terminal to a plurality of target destinations according to an exemplary embodiment of the present invention.

As shown in FIG. 7, respective paths to the plurality of targets A and C are shown. The route to each target site may be re-searched for a predetermined time or in response to a user's request, and only a route to one target site may be re-searched according to a user's selection.
