  • Publication number: 20100020764
    Abstract: According to one embodiment, a mobile communication system includes base stations each forming a wireless zone for wirelessly accommodating mobile terminals, and a control device accommodating the base stations. The control device includes a construction module, a prediction module and an instruction module. The construction module constructs a database regarding a history of handovers by the mobile terminals. The prediction module predicts a base station of the next connection destination of a mobile terminal being in communication and timing of a handover to the base station of the next connection destination on the basis of the database. The instruction module instructs the handover to the predicted base station to the mobile terminal being in communication before the timing comes.

  • Publication number: 20100010698
    Abstract: A charging system that facilitates tracking of a stolen charging subject. The charging subject includes a battery and has a unique identification code. A charging device is connected to the battery of the charging subject by an electric cable, and the battery is chargeable. A server is connected to either one of the charging device and the charging subject and manages charging of the charging subject with the charging device. The server is cable of registering an identification code of the charging subject. The server obtains the identification code from the charging subject, determined whether or not the obtained identification code is registered in the server, and transmits to the charging device a charging prohibition command for prohibiting charging of the charging subject with the charging device when the obtained identification code is not registered in the server.

  • Publication number: 20090185529
    Abstract: A mobile communication system which can prevent deterioration of a utilization ratio of a radio channel and degradation of communication quality is provided. The mobile communication system has a mobile terminal, base station, and a base station controller. The mobile terminal issues a link channel establishment request in order to communicate with another mobile terminal. The base station receives the link channel establishment request, and outputs a radio channel assignment request. When the base station controller receives the radio channel assignment request, the base station controller assigns the base station a radio channel which is not used in the base station and its adjacent base station and outputs a radio channel assignment answer. When the base station receives the radio channel assignment answer, the base station returns a link channel assignment answer to the mobile terminal, and establishes a communication connection with the mobile terminal by an assigned radio channel.
