PROBLEM TO BE SOLVED: To perform proper re-route processing even when using a mobile communication device which does not have a sensor for detecting an azimuth or a sensor for detecting an above ground level.SOLUTION: A mobile communication device 1 includes a route data memory 25 for storing route data indicating a set route, a GPS processing unit 13, a position history data memory 23 for time-serially accumulating position information of the mobile communication device, a re-route requirement decision unit 171 for determining whether the mobile communication device is moving along the set route, a moving speed estimation unit 172, a set route decision unit 173 for determining the type of road at a location immediately prior to a deviation from the set route, a re-route start point setting unit 175 for specifying the start point of re-routing and its type of road, and a route search requesting unit 15 for generating a route search request including information indicating both of the start point of re-routing and the type of road specified by the re-route start point setting unit 175. |
