  • Patent number: 10935390
    Abstract: A communication terminal is connected to a server and transmits a route search request for a destination to the server and obtains a route searched for from the server according to the request. When setting a destination or transmitting the route search request to the server, the terminal requests the server for guidance information targeted for at least an update target area around a current location among update target areas. The guidance information is for providing movement guidance for a mobile unit, and the update target areas are areas whose terminal-side map information included in the terminal is an older version of map information relative to the server's device-side map information. The terminal receives the guidance information transmitted from the server according to the request for the guidance information, and provides the movement guidance for the mobile unit using a route set on the terminal and the received guidance information.
