Prior to the description, due to the increase in Point of Interest (POI) currently stored in the navigation, the destination is subdivided into a plurality of points of interest such as parking lots, front doors and back doors. The large area of the point is not only subdivided into more diverse entrances and multiple parking lots than the building, but also the distance between points of interest, despite being points of interest that share the same name.

Therefore, when a plurality of users who are moving to an appointment place want to move to another destination having the same name instead of the specific destination due to parking conditions, traffic conditions, or change of an appointment place to another similar destination, destinations may be mixed between users. Even if you notice the change of destination through contact, you must end the current route information through navigation and reset the other destination to complete the route guidance for the reset destination. However, the process of rerouting to another nearby destination is quite cumbersome and the route reversal process is a hazard to safety while driving.

To solve this problem, a route change system and method for preventing a case where a user moving to a similar destination and a route crossing to a similar destination according to an embodiment of the present invention and a device applied thereto will be described. It will be described in detail with reference to.

Hereinafter, a service device applied to a route change system according to an exemplary embodiment of the present invention will be described using a server as an example. However, various devices may be applied. However, a user device communicating with a service device will be described as an example. The present invention is not limited and various apparatuses may be applied.

1 is a view illustrating a configuration environment of a route change system according to an exemplary embodiment of the present invention. As illustrated, a traffic information providing server 210 and a route providing server 220 communicating with a user terminal 100 are illustrated. It may include.

In this case, the user terminal 100 includes a navigation unit 110 for communicating with the traffic information providing server 210 and the route providing server 220, the navigation unit 110 is an application installed in the user terminal 100 It may be implemented in the form of. In addition, the navigation unit 110 may include various applications that support route guidance and may include, for example, a map application.

In addition, the traffic information providing server 210 provides traffic information and point of interest (POI) information to the navigation unit 110 of the user terminal 100, and the route providing server 220 is received from the user terminal 100. The user route information generated by calculating the route according to the current location information and the destination information may be transmitted to the user terminal 100.

In this case, the traffic information providing server 210 and the route providing server 220 may be integrated into one server.

In addition, the route providing server 220 may transmit the user route information reflecting the traffic information to the navigation unit 110 of the user terminal 100 in association with the traffic information providing server 210 when the user route information is generated.

Accordingly, the navigation unit 110 included in the user terminal 100 may guide the route according to the user route information received from the route providing server 220.

In the above-described configuration, the path providing server 220 is another user having a overlapping section overlapping with the user path information among the path information corresponding to one or more other users previously stored in the contact information in the user's member information when generating the user path information The presence of route information can be determined.

For example, the route providing server 220 may be configured to temporarily store the route information until the user arrives at the destination according to the route information. Therefore, the route providing server 220 may be transmitted to a terminal of another user before generating the route information. By storing the other user's route information and retrieving the other user's route information at the time of generation of the user's route information, it is possible to extract other user's route information including the overlapping section overlapping with the user's route information and having different user route information and destination. .

At this time, the route providing server 220 has a overlapping section and compares the user route information and other user route information among the other user route information having different destinations, and has a difference in the estimated time of arrival or location according to the destination within a preset range. User route information can also be extracted.

Thereafter, the path providing server 220 may transmit the extracted other user path information and the user path information to the user terminal 100.

Accordingly, the navigation unit 110 of the user terminal 100 may display other user route information together with the user route information through the output unit of the user terminal to recommend the route of another user. In this case, the navigation unit 110 of the user terminal 100 displays the user route information and the other user route information in a different color so as to distinguish between the user route information and the other user route information, or is included in other user route information. The user information may be distinguished from the user route information by displaying the user information in addition to the other user route information.

Through such a configuration, the path providing server 220 recommends another user who is moving a path similar to the user to the user so that the user can identify another user that he / she wants to meet. Can be provided to match the destination with other users.

Thereafter, the navigation unit 110 of the user terminal 100 may generate user selection information according to a user input regarding whether to change to recommended other user route information, and transmit the generated selection information to the route providing server 220.

At this time, since the starting point of the user path information and the other user path information may not coincide with each other, the navigation unit 110 of the user terminal 100 uses the user path information even when other user path information is selected according to the selection information. You can guide the route.

In other words, the navigation unit 110 of the user terminal 100 may transmit only the selection information to the route providing server 220 and guide the route through the user route information regardless of the selection information.

Then, when the route providing server 220 receives the selection information and changes to other user route information, the current location of the user is based on the current location information of the user received in real time or non-real time from the user terminal 100. Transmit only the other user's path information to the user terminal 100 so as to change the path to the other user's path information at a point entering the overlapped section or any point within the overlapped section and change the user's path information to the other user's path information. You can.

That is, the route providing server 220 transmits only the other user route information to the user terminal 100 differently from the information transmitted from the first departure point, thereby easily changing the user route information to the other user route information in the user terminal 100. You can do that.

Accordingly, since the paths of the user path information and other user path information coincide with each other in the overlapping section, the navigation unit 110 of the user terminal 100 can easily change the user path information to other user path information to guide the path. The destinations of users and other users can be matched with each other.

Meanwhile, in the above configuration, the navigation unit 110 of the user terminal 100 may directly change the path to other user path information in the overlapping section.

For example, the navigation unit 110 of the user terminal 100 receives and temporarily stores the user route information and other user route information transmitted from the route providing server 220 at the origin, and the other user route information according to the selection information. In the case of changing the route, since the starting point of the user route information and other user route information may be inconsistent, the route may be guided by the user route information from the starting point to the overlapping section.

Thereafter, the navigation unit 110 of the user terminal 100 determines whether to enter the overlapping section based on the current location information of the user, and when entering the overlapping section, the user path information is temporarily stored as another user path information. By switching and changing, the route can be directed to the destination of another user without a route rescanning procedure.

In the above-described configuration, even if the user route information and the origin of other user route information coincide with each other, the navigation unit 110 of the route providing server 220 or the user terminal 100 may recognize a duplicate section from the origin. Therefore, by transmitting only the other user's route information from the departure point, the user's route information can be changed to other user's route information.

Through such a configuration, the route providing server 220 does not need to go through a separate route re-search process according to the user's route change request, and matches the destination of the user and the other user only by transmitting the route information of the other user. The users who set different destinations and the other users can be prevented from intersecting with each other.

On the other hand, the route providing server 220 includes a section overlapping with the user route information after the generation of the user route information, and when the other user route information different from the destination is generated, the point entering the overlapping section or the overlapping section Any user route information may be transmitted to the user terminal 100 together with push information for informing other user route information at any point belonging to the user terminal 100.

Accordingly, the navigation unit 110 of the user terminal 100 displays the push information and other user route information together with the user route information on map information, and selects information on whether to change to other user route information. It may be received through the user terminal 100 and transmitted to the path providing server 220.

Accordingly, the navigation unit 110 of the user terminal 100 displays the push information and the other user route information together with the user route information on the map information so that the user selects information on whether to change to other user route information. It may be received through the terminal 100 and transmitted to the path providing server 220.

In this case, the navigation unit 110 of the user terminal 100 may display only destination information included in other user route information received during route guidance, and other users included in other user's route information for identifying other users. Information can be displayed together.

Thereafter, when the route providing server 220 changes to other user route information according to the selection information received from the user terminal 100, the route providing server 220 immediately transmits the other user route information to the user terminal 100 without a separate route calculation, and the user. The navigation unit 110 of the terminal 100 may also guide the path by changing the user path information to other user path information immediately after receiving the other user path information.

As such, since the route providing server 220 changes the route in the overlapping section, which is a section where the user route information and the other user route information match, the route information server 220 immediately converts the user route information into the other user route information without going through a separate route calculation process. You can change it.

This may reduce the load of the path providing server 220 and may significantly improve the response speed according to the path change request of the user, thereby enabling rapid path change and path guidance.

In this case, when the generation time of the user path information is earlier than the generation time of the other user path information, the path may be changed in the navigation unit of the other user terminal by recommending the user path information to the other user terminal.

In addition, in this case, since the other user terminal changes the path with the user path information to match the path with the user terminal 100, it is not necessary to provide the path information of the other user to the user terminal 100.

As described above, the navigation unit 110 of the user terminal 100 guides the route through the route information of the other user from the overlapping section, so that the user's destination can be easily used without having to go through a separate route calculation process. Can match the destination of.

In addition, when the other user is an acquaintance associated with the user through the above-described configuration, the user and acquaintances set different interest points having duplicate names as destinations in the process of searching for a point of interest with a specific name and setting it as a destination. In this way, it is possible to prevent the destinations from intersecting between users and acquaintances.

In this case, the acquaintance may include other users whose contact information is stored in the member information corresponding to the user of the user terminal 100, and is received from the user terminal 100 among other users stored in the member DB. It may include other users matching the acquaintance information, and may include other users selected by the path providing server 220 through the information transmitted from the user terminal 100.

Based on the above, the detailed configuration of the user terminal 100 in communication with the route providing server 220 and the traffic information providing server 210 will be described in detail with reference to FIG. 2. As shown in the navigation unit 110, the navigation unit 110 communicates with the traffic information providing server 210 and the route information providing server 220 to guide the route, POI management unit 111, the route as shown It may include a providing unit 112, a path guide unit 113 and the interface unit 114.

First, the interface unit 114 includes a GPS unit 120, an application unit 130, a user input receiving unit 140, a memory unit 170, and an output unit 160 configured in the navigation unit 110 and the user terminal 100. And a communication interface with the communication unit 150.

Accordingly, the POI management unit 111 may communicate with the traffic information providing server 210 through the communication unit 150 to receive traffic information, map information, point of interest (POI) information, and the like, and store them in the memory unit 170. .

In addition, the path providing unit 112 communicates with the path providing server 220 through the communication unit 150, and receives the current location information of the user received through the GPS unit 120 and the user input receiving unit 140. The destination information may be transmitted to the route providing server 220 to receive user route information generated according to the current location information and the destination information from the route providing server 220. In this case, the GPS unit 120 may be replaced by a location measuring unit that measures a location using WiFi, CELL ID, and the like as well as GPS.

In addition, the route providing unit 112 may match the user route information received from the route providing server 220 with the map information stored in the memory unit 170 and provide the route information to the route guide unit 113.

Accordingly, the route guide unit 113 may guide the route by outputting the user route information and the map information through the output unit 160.

In the above-described configuration, the path providing unit 112 may be synchronized with the application unit 130 storing contact information of an acquaintance related to the user, and transmit the contact information of the acquaintance to the path providing server 220.

Accordingly, the route providing server 220 may store acquaintance information including contact information of acquaintances in the member DB in response to the user information of the user, and the navigation unit 110 included in the acquaintance terminal corresponding to the acquaintance information. The acquaintance route information generated according to communication with the mobile terminal 100 may be transmitted to the navigation unit 110 of the user terminal 100. In this case, the route providing server 220 may include the acquaintance information in the acquaintance route information and transmit the acquaintance information.

In this way, the path providing unit 112 receives user path information and acquaintance path information transmitted from the path providing server 220 and displays the user path information and acquaintance path information through the output unit 160.

Thereafter, the route providing unit 112 receives user input information for selecting any one of the user route information and the acquaintance route information through the user input receiving unit 140, and thus selects information on whether to change to the acquaintance route information. After generating the information may be transmitted to the path providing server 220.

At this time, the path providing unit 112 checks the acquaintance information included in the acquaintance path information to distinguish the acquaintance path information from the user path information, and displays the acquaintance information through the output unit 160 along with the acquaintance path information. Information and acquaintance route information can be displayed separately.

In addition, the route providing unit 112 may transmit acquaintance information including contact information of acquaintances to the route providing server 220 according to a user input through the user input receiving unit 140, and the acquaintance from the route providing server 220. The acquaintance route information corresponding to the information may be received.

On the other hand, the path providing unit 112 transmits the current location information of the user to the path providing server 220 when the acquaintance path information is selected, and transmits the user path information to the path guide unit 113 regardless of the selection information. The route may be guided according to the route information.

Thereafter, the route providing unit 112 receives acquaintance route information from the route providing server 220 in the overlapping section where the user route information and the acquaintance route information overlap during the route guidance. By providing, through the route guide unit 113 can be made to route guidance according to acquaintance route information.

In this case, since the location or path of the user route information and the acquaintance route information are identical to each other in the overlapping section, the route providing unit 112 easily switches the route to the acquaintance route information, and transmits the acquaintance route information to the route guide unit 113. To guide the route.

On the other hand, the route providing unit 112 has an overlapping section overlapping with the user route information at the time of generating the user route information and does not receive the acquaintance route information from the route providing server 220 because the route information does not exist. If the path through the user path information.

Subsequently, when receiving acquaintance route information along with push information from the route providing server 220 in the overlapping section during route guidance, the route providing unit 112 receives the user's selection information regarding whether to change to acquaintance route information. A pop-up window and the acquaintance path information including the push information for the output may be output, and selection information on whether to change to the acquaintance path information may be generated according to a user input input to the pop-up window through the user input receiver 140.

In this case, the route providing unit 112 may output only the destination information included in the acquaintance route information together with the pop-up window.

In the case of changing to acquaintance route information according to the selection information, the route providing unit 112 transmits the selection information to the route providing server 220, and then receives only acquaintance route information excluding push information from the route providing server 220. User's route information can be immediately changed to acquaintance's route information.

Accordingly, the route providing unit 112 may provide acquaintance route information to the route guide unit 113 so that route guidance may be performed according to acquaintance route information.

In this case, when the route providing unit 112 changes to acquaintance route information according to the selection information, the route providing unit 112 does not need to transmit the selection information to the route providing server 220 when located within the overlapping section based on the current location information of the user. It may be immediately changed to acquaintance route information received along with the route information or push information.

For example, when the route providing unit 112 receives user route information and acquaintance route information from the route providing server 220 at the departure point and changes the acquaintance route information according to the selection information, the route information and acquaintance route until arrival. The information may be temporarily stored in the memory unit 170 and immediately changed into acquaintance route information when entering the overlapping section based on the current location information of the user through the GPS unit 120.

As another example, when the route providing unit 112 receives acquaintance route information along with push information from the route providing server 220 in the overlapping section and changes the acquaintance route information according to the selection information, the location of the current user is duplicated. Because it is a section, it can be immediately changed to acquaintance route information.

On the other hand, the user route information and the acquaintance route information may be changed in accordance with the traffic information, the route providing unit 112 to provide a route guidance reflecting the traffic information in real time or non-real time route providing server ( 220 may be transmitted to, and when the user terminal 100 is located in the overlapping section where the user route information and acquaintance route information reflecting traffic information from the route providing server 220 overlap each other, the acquaintance route from the route providing server 220. Receiving the information may be to guide the route according to the acquaintance route information instead of the user route information from the overlapping section.

As such, the navigation unit 110 included in the user terminal 100 receives the path information of an acquaintance related to the user from the path providing server 220, and changes the path information of the user to the path information of the acquaintance according to the user's selection. The route resetting procedure can be omitted because the user's route information can be replaced with the route information of acquaintances without calculating the route in the overlapping section, and the route information can be omitted. Meetings can be prevented.

Referring to the configuration of the route providing server 220 to provide a route change according to the above in more detail with reference to Figure 3, as shown, the route providing server 220 is a route calculation unit 222, location information collection unit ( 223 and the path changing unit 224.

First, the location information collection unit 223 may communicate with the navigation unit 110 included in the user terminal 100 to receive current location information of the user terminal 100 from the user terminal 100, and present location information. May be provided to the path calculator 222.

In addition, the route calculation unit 222 communicates with the navigation unit 110 included in the user terminal 100 to receive destination information, and calculates a route according to a preset route algorithm based on the current location information and the destination information. User route information can be created.

Next, the route calculator 222 may transmit the user route information to the user terminal 100 so that route guidance based on the user route information may be performed.

At this time, the route calculation unit 222 communicates with the traffic information providing server 210 that interworks with the route providing server 220, and is in real time or non-realistic from the traffic information providing unit 212 included in the traffic information providing server 210. The user route information may be updated by reflecting traffic information provided in real time in the user route information.

Meanwhile, the traffic information provider 212 may collect traffic information and store the traffic information in the traffic information DB 230, and may provide traffic information stored in the traffic information DB 230 to the route calculator 222. In addition, the traffic information provider 212 may provide traffic information to the user terminal 100 to output traffic information through the navigation unit 110 of the user terminal 100.

Accordingly, the route calculator 222 generates user route information reflecting traffic information and transmits the generated route information to the user terminal 100, thereby updating the existing route information.

In this case, the path calculator 222 may receive the current location information and the destination information from the acquaintance terminal 101 like the user terminal 100 to generate acquaintance route information, and convert acquaintance route information to the acquaintance terminal 101. The transmission may be routed through the navigation unit 110 included in the acquaintance terminal 101.

In the above-described configuration, in the process of setting a destination through the user terminal 100 and the acquaintance terminal 101 by sharing a destination under a common name with a user and an acquaintance, the user and the acquaintance are searched based on the duplicated name. It is possible to set a destination in which the remaining names are inconsistent with each other except for duplicate names between destinations set through the acquaintance terminal 101. In addition, when a plurality of points of interest match a single address because a region of the point of interest is wide, a different point of interest between the user terminal 100 and the acquaintance terminal 101 that search for a destination based on only the duplicate address may be set as a destination. It may be.

Accordingly, the destination information of the user terminal 100 and the location information of the point of interest corresponding to the destination information of the acquaintance terminal may be different from each other, and a user and an acquaintance who want to meet at the same place are alternated to different destinations.

As such, in order to prevent a user and an acquaintance from holding an appointment place to the same destination but moving from each other to a different destination by setting different destinations, the route providing server 220 may have at least one section in the user terminal 100. Recommend this overlapping acquaintance route information, and includes a route change unit 224 to provide the user route information provided to the user terminal 100 to the acquaintance route information provided to the acquaintance terminal 101.

First, the path change unit 224 is synchronized with contact information (or contact application) including contact information of an acquaintance already stored in the user terminal 100 through the navigation unit 110 and included in the member DB 240. Contact information may be stored in the member information of the contact information including contact information for at least one acquaintance. Of course, the path changing unit 224 may receive contact information of an acquaintance directly from the user terminal 100 and store the contact information of the user stored in the member DB 240.

In addition, the route changing unit 224 matches the route information provided to each terminal with the member information corresponding to the member DB 240 and stores the route information in the route information DB 250, and stores the route information from the route information DB 250. The user terminal 100 may be extracted and provided to the user terminal 100, and the user route information may be extracted from the route information DB 250 and provided to the terminal of an acquaintance.

At this time, the route changing unit 224 receives the user's current location information in real time or non-real time through the location information collecting unit 223 and arrives at a destination according to the user's route information or changes to acquaintance route information according to the user's movement. In this case, the user path information stored in the path information DB 250 may be deleted.

According to the configuration of the path changing unit 224 described above, when the user path information is generated in conjunction with the path calculation unit 222, acquaintance information from the user's member information stored in the member DB 240 Extract the path information, and search the path information corresponding to the acquaintance information in the path information DB 250 to determine whether the path information exists.

Thereafter, when the route information corresponding to the acquaintance information exists, the route changing unit 224 includes user route information and at least one overlapping section and extracts acquaintance route information having different destinations, and the route calculating unit 222. The interlocking path information is transmitted to the user terminal 100 together with the user path information, and the user path information and the acquaintance path information are displayed on the screen of the user terminal 100 through the navigation unit 110 of the user terminal 100. Can be displayed.

At this time, the path change unit 224 receives the user path information from the path calculator 222 when the path information is present when the path information is generated by the path calculator 222. Can be transmitted together to the user terminal.

In addition, the route changing unit 224 may control the route calculation unit 222 to transmit only the user route information when the destination is the same or there is no overlapping section between the user route information and the acquaintance route information.

Next, the path changing unit 224 may receive selection information on whether to change to acquaintance path information, and when the path changing unit 224 is changed to acquaintance path information according to the selection information, the current location of the user through the location information collecting unit 223. Information can be received in real time or non-real time, and only acquaintance path information can be transmitted to the user terminal 100 when the current location of the user is located within the overlapping section.

Accordingly, the navigation unit 110 of the user terminal 100 receives only acquaintance route information while moving the route according to the user route information, and may change the user route information into acquaintance route information, and guides the route according to the acquaintance route information. can do.

In addition, the route calculation unit 224 extracts contact information of an acquaintance corresponding to the acquaintance route information from the user's member information stored in the member DB 240 when the destination of the user is changed to a destination according to the acquaintance route information according to the selection information. Thus, the notification information about the user's path change may be transmitted to the acquaintance terminal 101.

Accordingly, the acquaintance may know that the destination is matched between the user and the acquaintance through the notification information.

On the other hand, the route changing unit 224 in conjunction with the route calculation unit 222 includes a duplicate section at the time when the user route information is generated, if there is no destination information with different destinations, the route calculation unit 222 controls the user As described above, only route information can be provided.

In this case, when the acquaintance route information including the overlapping section is generated after the user route information is generated, the route change unit 224 passes the user route information and the acquaintance to the acquaintance terminal 101 corresponding to the acquaintance route information. By transmitting the route information, an acquaintance may change the route according to the destination of the user as described above.

However, if the path changing unit 224 maintains the path according to the acquaintance path information according to the selection information received from the acquaintance terminal 101, the path changing unit 224 receives the current location information of the user through the location information collecting unit 223 and the user. May be determined to be located within the overlapping section, and if the location is within the overlapping section, acquaintance route information together with the push information may be transmitted to the user terminal 101.

Accordingly, when the navigation unit 110 of the user terminal 101 receives the push information during route guidance, the navigation unit 110 includes a pop-up window including push information for receiving selection information on whether to change to acquaintance route information together with acquaintance route information. The acquaintance route information may be output, and selection information on whether to change acquaintance route information according to a user input through a pop-up window may be transmitted to the route change unit 224 of the route providing server 220.

In this case, the navigation unit 110 of the user terminal 100 may output only destination information included in the acquaintance route information together with the pop-up window.

Thereafter, when the path change unit 224 is changed into acquaintance path information according to the selection information, only the acquaintance path information may be immediately transmitted to the user terminal 100 without interworking with the path calculator 222.

Accordingly, since the navigation unit 110 of the user terminal 100 coincides with the user route information and the acquaintance route information in the overlapping section, the user route information is directly changed to the acquaintance route information to route the route to the destination according to the acquaintance route information. I can guide you.

In addition, even when the route is changed during the route guidance of the user terminal 100, the route change unit 224 may transmit notification information to the acquaintance terminal 101, so that the acquaintance may recognize the user's destination change.

As such, the route changing unit 224 may allow the route information to be shared between a user and an acquaintance who are moving at the same time in real time to match the destination between the user and the acquaintance.

By doing so, the route providing server 220 provides a route change to the acquaintance route information in the user terminal 100, thereby preventing the destination from being mixed and does not require a destination resetting procedure for changing to acquaintance route information. Can support the safe operation of

In the above description, the path information sharing between the user and the acquaintance has been described, but the path changing unit 224 may allow each user path information to be shared between a plurality of users.

Meanwhile, as described above, some names except for duplicate names among the plurality of points of interest set as destinations are different or multiple points of interest are matched to the same address, thereby preventing the destinations from being staggered and similarity between destinations between users. To more accurately determine the path providing server 220 may further include a POI grouping unit 221.

In this case, the POI grouping unit 221 communicates with the POI providing unit 211 included in the traffic information providing server 210 to name point of interest information provided from the POI providing unit 211 of the traffic information providing server 210. Alternatively, POI group information may be generated by grouping at least one of the addresses.

For example, as illustrated in FIG. 4, the POI grouping unit 221 may group a plurality of points of interest information having names that overlap each other, and group a plurality of points of interest information having the same address to group one POI group information. Can be generated as

In addition, the POI grouping unit 221 may group a plurality of points of interest information having names that overlap each other and then regroup them into duplicate addresses. Accordingly, adjacent points of interest of the plurality of points of interest information having overlapping names may be adjacent to each other. Branch information may be grouped with each other to generate a plurality of POI group information.

In addition, the POI grouping unit 221 may store the POI group information in the POI group DB 260, and receive POI information continuously updated from the POI provider 211 to store the POI stored in the POI group DB 260. Group information can be updated continuously.

Accordingly, the route changing unit 224 may be interested in corresponding to the destination information included in the user route information through the POI group information stored in the POI group DB 260 among one or more acquaintance route information having a section overlapping with the user route information. POI group information to which the branch information belongs may be selected, and acquaintance route information including other point of interest information included in the selected POI group information as destination information may be provided to the user terminal 100.

In this way, the route changing unit 224 provides the acquaintance route information including the destination information adjacent to the destination information included in the user route information through the navigation unit 110 of the user terminal 100 to the user terminal 100. It is possible to automatically identify the acquaintances that meet the user, and by providing only the acquaintance route information that meets the user can accurately match the destination between the user and acquaintances.

In this case, the route changing unit 224 may be configured to provide acquaintance route information to the user terminal when the destination information included in the user route information and the acquaintance route information correspond to each other or when the destination information of the user route information and the acquaintance route information does not belong to the same POI group. 100) may not be transmitted.

In addition to the above-described configuration, the route changing unit 224 may receive at least one or more acquaintance information in addition to the current location information and the destination information from the navigation unit 110 included in the user terminal 100, and the route information DB 250. In the presence of acquaintance route information corresponding to the acquaintance information received from the navigation unit among the route information stored in the) may be provided to the user terminal 100, at least one acquaintance route information.

Accordingly, the route change unit 224 may transmit the acquaintance route information desired by the user to the navigation unit 110 of the user terminal 100 to more accurately match the destination between the user and the acquaintance.

5 to 6 are exemplary views showing a detailed embodiment of a process of changing to acquaintance route information according to communication between the path providing server 220 and the user terminal 100 according to the above-described configuration, and is shown in FIG. 5. As described above, the route providing server 220 may provide different route information to the user terminal 100 and the acquaintance terminal 101 that set different points of interest having different names or addresses as destinations.

Accordingly, the navigation unit 110 included in the user terminal 100 and the acquaintance terminal 101 may guide the route with different route information.

Meanwhile, the route providing server 220 matches one or more acquaintance information stored in the member information corresponding to the user terminal 100 with the route information DB 250 at the time of generating the user route information corresponding to the user terminal 100. It is determined whether there is acquaintance information provided with the route information, and if there is one or more overlapping sections A to B overlapping with the user route information among at least one route information matching the acquaintance information provided with the route information, The route information may be extracted from the route information DB 250, and the extracted acquaintance route information may be provided to the user terminal 100 to be recommended.

In this case, the route providing server 220 extracts acquaintance route information within a preset range of arrival time or position difference according to the user route information and the destination from the acquaintance route information including the overlapping section and transmits the acquaintance route information to the user terminal 100. It may be recommended.

In this case, the overlapping section may be configured as one node. In other words, the overlapping section may be composed of points overlapping each other between user route information and acquaintance route information.

In addition, the route providing server 220 may not recommend acquaintance route information when the destination information of the user route information and the destination information of the acquaintance route information extracted from the route information DB 250 coincide with each other.

Meanwhile, the route providing server 220 may determine whether the route is being guided based on the presence of acquaintance route information based on the generation time point of the user route information.

In other words, since the route information can be performed by the user terminal 100 after the route information is transmitted, the acquaintance route information and the acquaintance route information including the overlapped section at the time of the generation of the user route information and having different destinations already exist. When the route information is transmitted together, it may be determined as an initial route selection step, and thus, it may be determined that the route information is not being guided.

Accordingly, when the route is not in use, the user route information (①) and acquaintance route information (②) are transmitted to the user terminal 100 together, and the user route through the navigation unit 110 of the user terminal 100 is illustrated. Information (1) and acquaintance route information (2) may be displayed on the map information to be recommended.

For example, as shown in FIG. 5, when the path providing server 220 has at least one or more overlapping sections with the user path information at the time of generating the user path information and the destination information exists, the path information may be different from the user. The route information and the acquaintance route information may be transmitted to the navigation unit 110 of the user terminal 100.

In this case, the route providing server 220 compares the user route information and the acquaintance route information, but when there is a overlapping section, if only the destinations coincide with each other, the route providing server 220 transmits only the user route information to the user terminal 100 according to the user route information. Route guidance can be made.

Meanwhile, as shown in FIGS. 5 and 6 (a), when the destinations do not coincide with the user route information and the acquaintance route information, the route providing server 220 receives the point of interest information about '00 hospital parking lot 'as the destination information. Transmit the acquaintance route information (①) and acquaintance route information (②) having the point of overlap with the user route information and the point of interest information of the '00 hospital front door 'as the destination information to the user terminal 100; The display may be recommended through the navigation unit 110 of the user terminal 100.

Thereafter, the navigation unit 110 receives selection information on whether to change to acquaintance route information according to selection of one of user route information and acquaintance route information from the user terminal 100 to the route providing server 220. If the acknowledgment route information is selected based on the received selection information, the route providing server 220 may locate the user terminal 100 in the overlapping section based on the current location information of the user as illustrated in FIG. 5. By transmitting only the path information of acquaintances, the user path information may be changed into acquaintance path information from the overlapping section so as to be guided to the path according to the acquaintance path information.

Accordingly, the navigation unit 110 of the user terminal 100 guides the route according to the user route information from the starting point to before the overlapping section, and the route according to the route information from the overlapping section as shown in FIG. 6 (c). Can be guided to.

At this time, when the navigation unit 110 of the user terminal 100 transmits the current location information of the user in non-real time, the path from any location within the overlapping section located at the time when the acknowledgment path information is received from the path providing server 220. You can also guide.

On the other hand, the route providing server 220 matches the acquaintance information corresponding to the user terminal 100 with the route information DB 250, if there is a section overlapping with the user route information, but there is no acquaintance route information different from the destination route The information may not be provided and the navigation unit 110 of the user terminal 100 may guide the route according to the user route information.

Accordingly, when the route providing server 220 transmits the user route information to the user terminal 100 and is guiding the route through the navigation unit 110 included in the user terminal 100, the route providing server 220 is a user. After the route guidance of the terminal 100 includes overlapping sections overlapping with the user route information among the route information generated for the acquaintance terminal 101 for transmitting the location information and the destination information, and whether or not the presence of acquaintance route information is different from the destination You can judge.

Accordingly, when the route information is included after the route guidance (after the user route information is generated) and the destination information with different destinations is generated, the route providing server 220 as shown in FIG. Push to the presence of acquaintance route information at the point where the user terminal 100 enters the overlapping section or any point belonging to the overlapping section through the current location information received from the user terminal 100 during the route guidance of 100. Push information may be provided to the user terminal 100.

In addition, the route providing server 220 may transmit acquaintance route information together with the push information to the user terminal 100, and together with the user route information on the map information through the navigation unit 110 of the user terminal 100. Push information and acquaintance route information may be displayed.

In this case, when there are a plurality of overlapping sections overlapping between the user route information and the acquaintance route information, the route providing server 220 may repeat the remaining sections except for the overlapping section where the user terminal 100 passes based on the location information of the user terminal 100. Provides acquaintance route information and push information to the user terminal 100 in the overlapping section which is located at the beginning of the section, and receives selection information on whether to change acquaintance route information from the user terminal 100 to acquaintance route information. When changing, only the path information of the acquaintance may be transmitted to the user terminal 100 to change the user path information into acquaintance path information.

For example, among the plurality of overlapping sections overlapping between the user route information and the acquaintance route information, the acquaintance route information is generated during the route guidance according to the user route information of the user terminal 100, and the user terminal 100 is located in the second overlapping section. In this case, the route providing server 220 may change acquaintance route information to the acquaintance route information by transmitting acquaintance route information when located within the second overlapping section.

In addition, the route providing server 220 displays the push information through the navigation unit 110 of the user terminal 100 and selects information on whether to change from the user terminal 100 to acquaintance route information in response to the push information. If it is changed to acquaintance route information on the basis of the received selection information, as shown in Figure 6 (c) by transmitting the acquaintance route information to the user terminal 100 to the '00 hospital front door 'as a destination , Through the navigation unit 110 may be guided to the path according to the acquaintance route information.

As such, when acquaintance route information is generated during route guidance, the route providing server 220 provides acquaintance route information to the user terminal 100 from the overlapping section where the user route information and the acquaintance route information overlap each other. Since the location information of the user route information and the acquaintance route information is the same as each other, the route providing server 220 may immediately change from the user route information to the acquaintance route information without rerouting according to a separate destination setting.

In addition, the path providing server 220 provides the user route information to the acquaintance terminal 101 when the user terminal 100 can no longer enter the overlapping section after passing the overlapping section, so that the acquaintance terminal 101 provides the user's route information with reference to FIGS. According to the path changing process described with reference to FIG. 6, it may be induced to change acquaintance path information into user path information.

Meanwhile, when the selection information is not received for a predetermined time from the time of providing at least one of acquaintance route information and push information for receiving selection information, the route providing server 220 of the navigation unit 110 of the user terminal 100. By removing the acquaintance route information and push information loaded on the screen of the user terminal 100, it can be guided to the path according to the user route information.

Meanwhile, as shown in FIG. 7, when the path providing server 220 receives the selection information from the user terminal 100, the path providing server 220 notifies whether the user changes the path according to the received selection information. The information may be transmitted to the acquaintance terminal 101 and displayed on the screen of the acquaintance terminal 101 for a predetermined time through the navigation unit included in the acquaintance terminal 101.

Accordingly, the acquaintance of the acquaintance terminal 101 may check whether the user's path is changed through the notification information. In this case, the route providing server 220 may further provide acquaintance route information corresponding to the notification information.

In addition, when a plurality of acquaintances route information is transmitted to the user terminal 100, the route providing server 220 matches each member information stored in the member DB 240 to recognize each acquaintance through the route information DB 250 in which the route information is stored. The member information of an acquaintance corresponding to the route information may be extracted, and the notification information may be transmitted for each acquaintance terminal 101.

Accordingly, each acquaintance terminal 101 that has received the notification information may change the route information according to the received notification information or maintain the existing route information, so that the route providing server 220 may share the same route with the user. And to join the destination.
