Meanwhile, the map information calculator 263 may calculate the route detailed map information as the route essential map information for the main living area according to a user request or according to the policy of the information providing service apparatus 200. In addition, when there is a new destination input, the map information calculator 263 may calculate the path essential map information for the previous main living area, and calculate the detailed map information from the main living area to the new destination. Route detailed map information and route essential map information calculated by the map information calculator 263 may be transmitted to the information provider 265.

The information provider 265 is configured to provide the user terminal 100 with various route related information calculated by the map information calculator 263.

That is, the information providing unit 265 collects the changes when the path changes, such as when a particular road is closed or a new road is generated, and transmits the changes to the user terminal 100 as update information of the corresponding living area information. Can provide.

On the other hand, when the information providing unit 265 receives a message requesting a search for a new destination from the user terminal 100, the information providing unit 265 provides information related to the route from the current location to the destination, and the map is divided by predetermined sections according to the movement of the user terminal 100. At least one of detailed route information and essential route map information provided by the information calculator 263 may be provided. For example, when the map information calculator 263 calculates and provides part of the detailed route information and essential route map information from the current location to the new destination, the information providing unit 265 divides the required route map information for each section. As the user terminal 100 moves, the terminal may be provided to the user terminal 100 for each corresponding section. In addition, the information providing unit 265 may provide the entire path essential map information calculated with a relatively small amount of data at a time when the path essential map information section is provided to the user terminal 100.
