PROBLEM TO BE SOLVED: To suppress a communication period allocated to a base station from being uselessly consumed.SOLUTION: First information including emergency information includes first specification information indicating a traveling direction of a mobile station 5A during emergency movement, and second information including the emergency information includes second specification information indicating the traveling direction of the mobile station 5A during emergency movement estimated by a first base station 2A. When receiving the first information including the emergency information and the first specification information, the first base station 2A generates the second information including the emergency information and the second specification information on the basis of the first information, and transmits the generated second information. When receiving the second information including the emergency information and the second specification information from the first base station 2A, the second base station 2B determines whether or not the mobile station during the emergency movement approaches an own station on the basis of the second specification information included in the second information, and when determining that the mobile station during the emergency movement is approaching the second base station 2B, the second base station 2B transmits third information including the emergency information.
【課題】基地局に割り当てられた通信期間が無駄に消費されるのを抑制する。【解決手段】緊急情報を含む第1情報は、緊急移動中の移動局5Aの進行方向を示す第1特定用情報を含み、緊急情報を含む第2情報は、第1基地局2Aが推定した緊急移動中の移動局5Aの進行方向を示す第2特定用情報を含む。第1基地局2Aは、緊急情報および第1特定用情報を含む前記第1情報を受信すると、当該第1情報に基づいて、緊急情報および第2特定用情報を含む第2情報を生成し、生成した前記第2情報を送信する。第2基地局2Bは、前記第1基地局2Aから前記緊急情報および第2特定用情報を含む第2情報を受信すると、当該第2情報に含まれる前記第2特定用情報に基づいて、前記緊急移動中の移動局が自局に接近しているか否かを判定し、前記緊急移動中の移動局が前記第2基地局2Bに接近していると判定されると、緊急情報を含む第3情報を送信する。【選択図】図17
