To provide a server capable of distributing information via a base station to a plurality of mobile bodies moving in a target distribution area while suppressing a rapid increase in downlink traffic from the base station for mobile communication.SOLUTION: A server determines a distribution area in which a plurality of mobile objects to be information-distributed are located, and on the basis of position information of the plurality of mobile objects located in the distribution area, a unicast transmission target mobile that transmits information by designating a destination from a server via a mobile communication base station is determined by selecting from the plurality of mobile objects within the distribution area, and information is transmitted to the mobile object of the unicast transmission target via the mobile communication base station.SELECTED DRAWING: Figure 1

    【課題】移動通信の基地局からの下りリンクのトラフィックの急増を抑制しつつ、対象の配信エリアを移動している複数の移動体に基地局を介して情報を配信することができるサーバを提供する。【解決手段】サーバは、情報配信対象の複数の移動体が位置している配信エリアを決定し、配信エリア内に位置している複数の移動体の位置情報に基づいて、移動通信の基地局を介してサーバから送信先を指定して情報を送信するユニキャスト送信対象の移動体を、配信エリア内の複数の移動体から選択して決定し、移動通信の基地局を介して前記ユニキャスト送信対象の移動体に情報を送信する。【選択図】図1
