The present invention relates to a method for updating map information of a terminal based on a search route and a server for the same, and more particularly, a route from a starting point to a destination using map version information, a departure point / arrival point information, and a route search method information transmitted from the terminal. The present invention relates to a method for updating map information of a terminal based on a search path, and a server for providing the updated map information to a terminal by searching for and extracting and updating update information of the surrounding map.

The route guidance service provided through telematics or location based service provides the driver of the vehicle with the current location of the vehicle, calculates the optimal route to the desired destination, and provides the driver according to the route. .

The conventional route guidance service is provided from the service providing server to the terminal.

Specifically, the service providing server provides map data to a terminal through a wireless network while numerically storing and storing map information. In addition, the terminal stores the map data, and visually guides the optimal route to the destination by using the stored map data. That is, the terminal provides numerical information about actual roads, buildings, and facilities according to a certain format. It stores the location information from the GPS (Global Positioning System) receiver corresponding to the pre-stored map data to guide the optimal route to the moving object and the destination to the screen.

However, since the route guidance service changes from time to time on actual roads, buildings, and facilities, the necessity of updating the map data used in the terminal is also updated to reflect the changed roads, buildings, and facilities.

Accordingly, the service providing server of the conventional route guidance service makes map information into data, divides and stores the region of the map into cells, and designates a street address for each of the divided cells. In this case, if the file size of the divided cells exceeds a predetermined size that can be transmitted through the wireless network, the service providing server repeats the process of subdividing them so that all the divided cells can be transmitted through the wireless network.

The service providing server transmits the entire data of the cell including the updated data to the terminal through the wireless network when some data of the divided cell area among the map data is updated. Then, the terminal receives the entire data of the cell including the updated data through the wireless network and updates the entire data of the region corresponding to the data of the received cell in the previously stored map data region.

In this case, since the terminal downloads and updates the data of the entire cell area including the updated data from the service providing server, a large amount of data must be downloaded. Accordingly, the terminal user must pay a high wireless network usage fee to update the map data.

In the above update method, the terminal capable of updating the partial map may be updated by being limited to the partial region selected by the user. However, the user may find it inconvenient to operate the terminal by requesting an update.

The present invention has been proposed to solve the above problems and to meet the above demands, and searches for a route from the starting point to the destination using the map version information, the starting point / arrival point information, and the route search method information transmitted from the terminal. It is an object of the present invention to provide a method for updating map information of a terminal based on a search route and a server for providing the updated map information to a terminal by extracting and updating update information of a route around a map.
