The present invention relates to a method for providing a moving route to a destination, and more particularly, to provide a road guidance service through a searched moving route to a mobile communication terminal user, and obtained in real time with the actual moving route of the user at predetermined time intervals. In order to provide a user with an optimal travel route reflecting real-time traffic information by notifying the mobile communication terminal of rescanning when a deviation from a preset error range is compared with each other by comparing the optimal search route re-searched with the traffic information. In addition, the present invention relates to a moving route providing method using real-time traffic information based on location.

Recently, a location based service (LBS) technology and a geographic information system (GIS) associated with satellite positioning system (GPS) technology have been linked. Information System (hereinafter referred to as "GIS") With the development of technology, it is possible to grasp the location and surrounding information of a person or object at any time, anywhere, or to be provided with a route information (destination information) to a destination.

In general, when a person wants to go to a destination located in a geographic area that is not well known, people can be provided with a route guidance service (e.g., "Nate Drive" of Eske Telecom Co., Ltd.) through a mobile terminal. After acquiring, we are moving to the destination along the route.

Such a road guidance system collects location information (eg, GPS satellite signals, access base station information, etc.) obtained from a mobile communication terminal to determine a user's current location, and various geographic information (eg; A map, route search information, address, point of interest (hereinafter referred to as "POI"), etc.) (also called GIS data) is provided to the mobile communication terminal.

On the other hand, recently, through the link between the road guidance system and the traffic control center to provide the driver with traffic information (road information) that changes every moment to move to the destination faster.

In this way, the road guidance service reflecting the real-time traffic information is searched differently depending on the road traffic conditions according to time zones for the same starting point and the same destination.

That is, the driver sets a starting point and a destination in the mobile communication terminal, and then applies for a road guidance service, and accordingly, the road guidance system searches for the shortest travel path by referring to the traffic information of the starting point and destination of the user and the service request time zone. Transmit to mobile communication terminal.

In the mobile communication terminal, a map, a road, route search information, and a POI are displayed on the screen. Accordingly, the driver moves to a destination along a road belonging to the corresponding movement route.

On the other hand, the driver may be driven by a data communication charge or a lack of awareness of the current location while driving, such as refraining from using the mobile terminal while driving (ie, lack of judgment on whether the current location is the right road or the like). At first, a route guidance system is requested to search for a route and is moved to a destination only through the route information provided accordingly. During the movement, a route search is not required through a manipulation of a mobile communication terminal.

However, when reflecting the real-time traffic information in the prior art as described above, since the travel time does not take much during the short distance route guidance, the movement route originally searched for the starting point and the destination greatly affects the road traffic state, etc. Although it takes no time to travel for long distance routes, the route originally searched for the starting point and destination is greatly influenced by road traffic conditions, so the route information after a certain time is completely different from the traffic information. It is not reflected.

Therefore, in the above conventional technology, the movement route originally searched for the starting point and the destination may not be an optimum movement route for the user's current position after a certain time, and thus a faster movement route with smooth communication with the driver. In spite of this, there is a problem that an incorrect travel path is provided.

In addition, the prior art as described above may provide a multi-travel route to a destination when the driver first requests for road guidance in consideration of traffic information by time zone, but the multi-travel route may also reflect traffic information in a service application time zone. After a certain period of time, however, the traffic information does not reflect the road traffic conditions, which are constantly changing.

In addition, even if the multi-path as described above is provided to the mobile communication terminal, due to the small system resources of the mobile communication terminal, the mobile communication terminal may process the multi-path to display each map, road, etc. according to the multi-path at the same time. The user can select only one route and check and move the map, road, etc. according to the route.

The present invention has been proposed in order to solve the above problems, and provides the user with a mobile navigation terminal through the searched moving paths while providing a road guidance service to the user's actual moving path and traffic information obtained in real time at regular intervals. A current location for providing a user with an optimum travel path reflecting real-time traffic information by notifying the mobile communication terminal of re-search by comparing the optimal search path re-searched with reference to each other and moving out of a preset error range. An object of the present invention is to provide a moving route providing method using real-time traffic information.

In order to achieve the above object, the present invention provides a method for providing a movement route to a destination, wherein when a starting point / destination is input from a mobile communication terminal, the mobile terminal is searched for an optimum movement route by referring to traffic information obtained in real time. Transmitting to the first step; A second step of receiving the current location information of the user at a predetermined time interval from the mobile communication terminal while providing a road guidance service to the user through the searched optimum movement path; A third step of identifying an actual moving path of the user based on the current location information of the user received at predetermined time intervals in the second step; A fourth step of re-searching the optimal moving route from the current location of the user, received at a predetermined time interval, to the destination by referring to the traffic information obtained in real time; A fifth step of comparing the actual moving path of the user identified in the third step with the optimum moving path re-discovered in the fourth step; A sixth step of waiting until the next current location information of the user is received from the mobile communication terminal if the actual moving path and the re-discovered optimum moving path fall within a preset error range as a result of the comparison of the fifth step; And a seventh step of notifying the mobile communication terminal of the rescanning when the actual moving path and the rescanned optimum moving path are out of a preset error range as a result of the comparison of the fifth step.

The present invention may further include: an eighth step of re-searching an optimum movement route with reference to traffic information obtained in real time when the current location / destination is re-entered from the mobile communication terminal as a result of the seventh step; And a ninth step of resuming the road guidance service to the user through the re-discovered optimum moving path.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed descriptions of well-known functions or configurations will be omitted if it is determined that the detailed description of the present invention may unnecessarily obscure the subject matter of the present invention. Terms to be described later are terms defined in consideration of functions in the present invention, and may be changed according to intentions or customs of users or operators. Therefore, the definition should be made based on the contents throughout the specification.

1 is a configuration diagram of an embodiment of a communication network to which the present invention is applied.

As shown in FIG. 1, a communication network to which the present invention is applied includes a mobile communication terminal 10 of a user (driver) side and movement path information (eg, map, road, route search information) to the mobile communication terminal 10. The mobile terminal 10 transmits a POI to a user by providing a road guidance service and compares the user's actual movement path with the re-discovered optimal movement path at regular intervals. The road guidance server 11 and the road guidance server 11 for notifying the re-navigation of the route to the road information server may provide various traffic information (eg, road traffic status (delay / slowness / seamage), traffic accident area, control section, etc.). It provides a traffic control center (12).

The mobile communication terminal 10 has a location determining function (eg, a function of grasping a user's current location through a GPS satellite signal or access base station information and transmitting the same to a road guide server 11) to perform a road guide service function. It is mounted.

The mobile communication terminal 10 transmits a departure point (current location) / destination received from the user to the road guidance server 11 to request a road guidance service, and accordingly, the mobile received from the road guidance server 11. Provides a route guidance service to the user through route information.

In addition, the mobile communication terminal 10 transmits the current location information of the user to the road guide server 11 through a data reverse channel at predetermined time intervals. At this time, the mobile communication terminal 10 is a mobile communication terminal identification information (for example, a terminal telephone number, a mobile communication terminal unique number (ESN; Eletronic Serial Number) or a mobile terminal identification number (MIN; Mobile Identification Number) or mobile A communication subscriber identification number (IMSI; International Mobile Subscriber Identity, etc.) or user identification information (eg, user name, social security number, etc.) may be transmitted to the road guidance server 11 together.

In particular, the road guidance server 11 receives the user's current location information from the mobile communication terminal 10 at predetermined time intervals, grasps the user's actual moving path through the user's current location information, and checks the traffic control center ( If the result of comparing the real movement route and the re-discovered optimal movement route of the user by re-searching the optimal movement route with reference to the traffic information acquired in real time from the real time from the mobile communication terminal 10, the mobile communication terminal 10 To request a re-routing request.

2 is a flowchart illustrating a method for providing a moving route using real-time traffic information based on a current location according to the present invention.

First, the mobile terminal 10 transmits a departure point / destination received from a user to the road guidance server 11 and requests a search for a movement route (200).

Then, the road guidance server 11 searches for the optimal movement route for the starting point / destination with reference to the traffic information provided in real time from the traffic control center 12 (201).

Here, the optimal travel route takes the shortest time from the starting point to the destination searched with reference to traffic information (eg, road traffic conditions (delay section / slow section / congestion section / control section) from the starting point to the destination obtained in real time). Says the path to be.

Then, the route guidance server 11 transmits the found optimal movement route to the mobile communication terminal 10 (202), and starts the route guidance service to the user through the optimal movement route (203).

Thereafter, the road guidance server 11 receives the user's current location information from the mobile communication terminal 10 at predetermined time intervals while providing the road guidance service to the user through the searched optimal travel path (204).

At this time, the current location information of the user is transmitted to the road guidance server 11 through a reverse channel (or reverse link or uplink) among data channels set between the mobile communication terminal 10 and the road guidance server 11. Information for identifying the communication terminal 10, that is, unique information such as mobile communication terminal or user unique information may be transmitted together. In addition, the current location information of the user is information obtained through a known GPS function.

On the other hand, it is preferable to set the current location information transmission and reception interval of the user in consideration of the total distance from the starting point to the destination and / or the moving (driving) speed of the user, and is set by the user or the road guidance application.

Then, the road guidance server 11 grasps the user's actual moving path through the user's current location information received at a predetermined time interval from the mobile communication terminal 10 (205). In particular, the road guidance server 11 grasps the user's actual moving path through the user's current location information, and checks the time required from the user's current location to the destination according to the actual moving path.

In addition, the road guidance server 11 refers to the traffic information acquired in real time from the traffic control center 12 to determine an optimal movement route from the current location of the user received at a predetermined time interval in the process “204” to the destination. Rescan (206). In particular, the road guidance server 11 re-searches the optimal travel route from the user's current location to the destination by referring to the traffic information obtained from the traffic control center 12, and then the Check the time required from your current location to your destination.

Thereafter, the road guidance server 11 compares the user's actual travel path identified in step 205 with the optimal search path re-discovered in step 206 (207). In particular, the road guidance server 11 compares the time required from the user's current location to the destination according to the actual moving path and the time required from the user's current location to the destination according to the re-discovered optimum moving path.

As a result of the comparison 207, when the road guidance server 11 detects the actual movement path of the user identified in step 205 and the optimum movement path re-discovered in step 206, the path guide server 11 falls within a preset error range. The process proceeds to step 204 "and waits until a predetermined time elapses until the next current location information of the user is received from the mobile communication terminal 10.

Here, if the time required from the user's current position to the destination according to the actual movement route is less than the time required from the user's current position to the destination according to the re-discovered optimal movement route, the driver may properly recognize the found optimal movement route. You can see that you are driving on the right path at normal speed (or the road speeds up after the first road guidance service, etc.), so that you can drive the path without having to re-search. will be.

On the other hand, it is preferable to set the error range in consideration of the delay time of not affecting the arrival time of the destination by referring to the delay time of transmitting / receiving the current location information of the user and / or the distance from the current location of the user to the destination.

If the comparison result 207, the road guidance server 11, the user's actual movement path detected in the step "205" and the optimal movement path re-discovered in the step "206" is out of a predetermined error range mobile communication The terminal 10 is notified to rescan the moving path (208).

Here, when the time required from the user's current position to the destination according to the actual movement route is greater than the time required from the user's current position to the destination according to the re-discovered optimal movement route, the driver may not recognize the optimal traveling route properly. You may know that you have traveled on a different road (or after the first road guidance service, the road traffic may not be smooth and the driving speed decreases, etc.), and the user may be notified to rediscover the moving route. Accordingly, the user sets the current location as the starting point through the mobile communication terminal 10 and sets the destination to request the road guidance server 11 to rescan the moving path.

Accordingly, the mobile communication terminal 10 transmits the current location (origin) / destination received from the user to the road guidance server 11 and requests re-search for the moving path (209).

Thereafter, the road guidance server 11 re-searches the optimal travel path for the current location (origin) / destination of the user with reference to the traffic information provided in real time from the traffic control center 12 and then the mobile communication terminal 10. ) And the mobile terminal 10 resumes the route guidance service through the changed movement route information to perform the subsequent process.

Those skilled in the art to which the present invention pertains may modify or alter the present invention in various forms within the principles and scope described in the claims herein.

The present invention as described above, by comparing the user's actual movement path and the real-time traffic information obtained in real time at regular intervals, and compares each other with the re-discovered optimal movement route and notifies the moving route re-discovery if it is outside the preset error range. By doing so, there is an effect of accurately determining whether the user is moving on the right path or at the normal speed or whether the initially discovered moving path is in good communication.

In addition, the present invention has the same effect as providing the user with a multi-movement path reflecting the traffic information that is changing from time to time with respect to one movement route reflecting the traffic information of the starting point / destination and the service request time zone first input from the user I can make it.                     

In addition, the present invention notifies the user to rescan the moving route according to the determination result of the rescanning of the moving route at predetermined time intervals, and accordingly the user downloads the map from the server side, thereby burdening the user with the data download fee. It has the effect of relieving you.

In addition, the present invention is to determine whether to re-search the moving path on the server side based on the current location information of the user received through the data reverse channel from the mobile communication terminal, and instructs the mobile communication terminal to search again. Accordingly, since the mobile communication terminal can receive an optimal movement path only through the current location / destination input, there is an effect of reducing the load on the mobile communication terminal having less system resources.
