Abstract

A road guide service system and a method thereof are provided to conduct road guide for a user by using photo information added with road guide announcements and progressing direction symbols indicative of next progressing directions of a road, thus the user can easily go and see even a road new to the user. A mobile communication terminal(100) accesses a road guide server(200), and sends the current location information and destination information to the server to demand road guide(S10-S16). The server sends map information for displaying a searched optimal path on a map to the terminal(S18-S22). The terminal perceives location information in real time, and periodically transmits the perceived location information to the server(S24-S30). The server searches photo information added with road guide announcements and progressing direction symbols to send the searched information to the terminal(S32,S34). If it is decided that the terminal arrives at the destination, the server transmits photo information indicative of the destination to the terminal, and completes a road guide service(S36-S40).

4 is a flowchart illustrating a method for providing a road guide service according to an embodiment of the present invention.

First, when a terminal user who wants to receive the road guidance service accesses the road guidance server 200 through the wireless Internet using the mobile communication terminal 100, the road guidance server 200 is connected to the mobile communication through the wireless Internet. The road guide service web page is provided to the terminal 100 (S10).

When the road guidance service web page is provided from the road guidance server 200 connected through the above-described process S10, the mobile communication terminal 100 is provided from the terminal user through the road guidance service web page provided by the road guidance server 200. After receiving the destination (S12), and receiving the destination from the terminal user, by using the GPS signal received through the GPS receiver to determine the current location of the terminal user (S14), the current location information of the identified terminal user and the A road guide request message including the destination information received in step S12 is generated and transmitted to the road guide server 200 connected to the wireless Internet through the mobile communication network 150 (S16).

The route guidance server 200 receiving the route guidance request message through the process S16 may determine an optimal route from the current position to the destination based on the current location information and the destination information of the terminal user included in the route guidance request message. Search (S18).

Subsequently, the mobile terminal 100 generates map information displaying the optimal route searched in step S18 on the map (S20), and transmits the generated route information request message through the step S16. (S22).

The mobile communication terminal 100 receiving the map information transmitted by the road guidance server 200 through the process S22 described above temporarily stores the received map information in a predetermined memory area (S24), and then receives the received map information. The display is displayed on the screen so that the terminal user can check the entire path (S26).

The terminal user who confirms the map information displayed on the screen display unit through the process S26 is moved toward the destination with reference to the map information. The mobile communication terminal 100 is configured to move the terminal user who has confirmed the map information toward the destination. According to the position information that changes according to the GPS signal received through the GPS receiver in real time (S28), and the current position information of the identified terminal user is periodically transmitted to the road guidance server 200 (S30).

Based on this, it is determined whether there is photo information to be provided to the terminal user (S32).

In the above-described process S32, when it is assumed that the road guidance server 200 provides picture information at intersections, intersections, intersections, landmarks, and the like, so that the terminal user requesting directions can easily visit a destination, When the server 200 approaches within a predetermined distance to an intersection, a branching point such as a crossroad, a landmark, or the like, to which the terminal user provides photo information, based on the current location information of the terminal user received from the mobile communication terminal 100. At this point, the photo information to be provided to the terminal user is searched in advance, and the terminal user can transmit the photo information to the mobile communication terminal to confirm the surrounding facilities and the direction of the future ahead of the arrival at the point. It is desirable to.

If there is photo information to be provided to the terminal user as a result of the determination in step S32, the retrieved photo information is transmitted to the mobile communication terminal 100 (S34).

When the mobile communication terminal 100 displaying the map information received through the process S22 and providing the terminal user with the received picture information transmitted by the road guidance server 200 through the process S34, the received photo The information is displayed on the map information for a predetermined time so that the terminal user can easily find the way with reference to the received photo information (S36).

Thereafter, the road guidance server 200 determines whether the mobile communication terminal 100 has reached the destination based on location information periodically received from the mobile communication terminal 100 moving toward the destination with reference to the map information and the picture information. It is determined (S38).

As a result of the determination in step S38, when the mobile communication terminal 100 does not reach the destination, the process proceeds to step S30 and based on the location information periodically received from the mobile communication terminal 100, the terminal. If there is photo information to be provided to the terminal user according to the direction of the terminal user at the current location of the user, the process of transmitting the retrieved photo information to the mobile communication terminal 100 is repeated.

On the other hand, when the mobile communication terminal 100 reaches the destination as a result of the determination in step S38, the photo information indicating the destination is transmitted to the mobile communication terminal 100 (S40), and the road guidance service is terminated.

5 is a road showing an example of map information and photo information provided to a mobile communication terminal requesting road guidance according to an embodiment of the present invention, and a mobile communication terminal connected to the road guidance server 200 through the wireless Internet ( When 100) requests the way to the Woori Bank Myeongdong branch from the SKT tower where the current terminal user is located, the road guide server 200 searches for the optimal route from the SKT tower to the Woori Bank Myeongdong branch, and then maps the searched route. The map information displayed on the screen is transmitted to the mobile communication terminal 100, and the mobile terminal 100 transmits the map information to the mobile communication terminal 100 based on the location information periodically transmitted by the mobile communication terminal 100 according to the movement of the terminal user who has confirmed the map information. When the picture information to be transmitted is found, the retrieved picture information is transmitted to the mobile communication terminal 100 so that the terminal user can easily reach the destination.
