PROBLEM TO BE SOLVED: To provide a communication system capable of suppressing that a communication period allocated to a base station is wastefully consumed.SOLUTION: A communication system is provided with: a first base station 2A; and a second base station 2B. First, second, and third pieces of information include emergency information for notifying that a mobile station is in emergency movement. The first information including the emergency information incudes first specification information showing a travel direction of the mobile station in the emergency movement, and the second information including the emergency information includes second specification information showing a travel direction of the mobile station in the emergency movement estimated by a first base station. The first base station is constituted to generate the second information including the emergency information and the second specification information, and to transmit the generated second information when the first information is received. A second base station is constituted to determine whether or not the mobile station in the emergency movement approaches an own station when the second information is received from the first base station, and to transmit the third information including the emergency information when it is determined that the mobile station in the emergency movement approaches the second base station.SELECTED DRAWING: Figure 17
【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できる通信システムを提供する。【解決手段】通信システムは、第1基地局2Aと、第2基地局2Bと、を備える。第1、第2および第3情報は、移動局が緊急移動中であることを通知する緊急情報を含む。緊急情報を含む第1情報は、緊急移動中の移動局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基地局が推定した緊急移動中の移動局の進行方向を示す第2特定用情報を含む。第1基地局は、第1情報を受信すると、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、生成した第2情報を送信するよう構成されている。第2基地局は、第1基地局から第2情報を受信すると、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、緊急移動中の移動局が第2基地局に接近していると判定されると、緊急情報を含む第3情報を送信するよう構成されている。【選択図】図17
