To realize stable radio communication when remotely monitoring a mobile entity by radio communication.SOLUTION: The present invention comprises: a position radio quality storage unit for storing position radio quality information in which a position for each radio communication scheme and radio frequency band in a route information provision target region and radio communication quality at the position are recorded in association; a cost calculation unit for performing weighing on the basis of position radio quality information corresponding to the radio communication scheme and radio frequency band usable by a mobile entity, so that radio communication quality at a position on the route is poorly evaluated as being bad for a route candidate; and a route search unit for searching for a route on the basis of weighting from among the weighted candidates for the route.SELECTED DRAWING: Figure 1
