1. A mobile communication system comprising:

  • a plurality of fixed base stations that are serially disposed along a moving direction of a moving body capable of high-speed moving and that are connected to a public telephone network;

    a mobile terminal that is possessed by a user who gets on the moving body; and

    a mobile base station that is capable of being connected to the plural fixed base stations and that is put in or on the moving body, wherein;

    triggered by an entrance of the mobile terminal into a communication area of the mobile base station and by a start of the moving body, the mobile terminal performs handover from a fixed base station that has been connected to the mobile terminal to the mobile base station;

    while the moving body is moving, the mobile base station sequentially performs handover to an adjacent fixed base station when the moving body enters into a communication area of the adjacent fixed base station; and

    when the moving body approaches a stop, the mobile terminal performs handover from the mobile base station to a fixed base station that covers a communication area around the stop.
