To provide a technique that can promptly start radio communication.SOLUTION: A mobile communication system includes a radio control station that searches for an on-vehicle mobile station that can be communicatively connected by changing an orientation direction of a transmission beam. The radio control station includes: a transmission antenna that forms the transmission beam; an information generation unit that generates information indicating a lamp color of a traffic light on a road on which the on-vehicle mobile station is located based on a signal control command given to a control device of the traffic light; and a transmission antenna control unit that changes a variable range of the orientation direction of the transmission beam according to the information.SELECTED DRAWING: Figure 5
【課題】速やかに無線通信を開始することができる技術を提供する。【解決手段】 通信接続可能な車載移動局を、送信ビームの指向方向を変化させて探索する無線制御局を備えた移動通信システムであって、前記無線制御局は、前記送信ビームを形成する送信アンテナと、前記車載移動局が位置する道路における交通信号機の灯色を示す情報を、前記交通信号機の制御装置に与えられる信号制御命令に基づいて生成する情報生成部と、前記情報に応じて、前記送信ビームの指向方向の可変範囲を変更する送信アンテナ制御部と、を備える。【選択図】図5
