Abstract:
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 first communication area of the mobile base station and by a start of the moving body, the mobile terminal performs a first handover from one of the fixed base stations that has been connected to the mobile terminal to the mobile base station; while the moving body is moving, the mobile base station initiates and sequentially performs a second handover to an adjacent one of the fixed base stations when the moving body enters into a second communication area of the adjacent one of the fixed base stations; and when the moving body approaches a stop, the mobile terminal initiates a third handover from the mobile base station to another of the fixed base stations that covers a third communication area around the stop, so that the mobile terminal communicates directly with the another of the fixed base stations and does not communicate via the mobile base station, wherein the mobile base station is separate and distinct from the mobile terminal.
