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
【課題】無線通信により遠隔で移動体を監視する際に安定的な無線通信の実現を図る。【解決手段】経路情報提供対象地域の無線通信方式及び無線周波数帯ごとに位置と当該位置における無線通信品質とが関連付けて記録された位置無線品質情報を格納する位置無線品質格納部と、移動体が利用可能な無線通信方式及び無線周波数帯に対応する位置無線品質情報に基づいて経路の候補に対して経路上の位置における無線通信品質が悪いと低評価になるように重み付けを行うコスト算出部と、重み付けがされた経路の候補の中から重み付けに基づいて経路を探索する経路探索部と、を備える。【選択図】図1
