  • Mobile telecommunication method and system
    Patent number: 5842132
    Abstract: A mobile radio communication method and a mobile radio communication system arranged in which as to a personal station (PS) located in a moving object equipped with a personal base station (CS), a position is registered with respect only to CS within the moving object. In this communication system, a connector is provided which connects a personal station (PS) possessed by a rider of the moving object to CS within the moving object. The personal station (PS) connected to the connector issues a position register demand through the connector to CS within the moving object. Subsequently, this personal station periodically issues the position register demand only to CS within the moving object in the form of electromagnetic waves until the level of the electromagnetic waves transmitted from CS within the moving object becomes lower than a predetermined value. The personal base station (CS) accepts only the position register demand issued from PS connected to the connector.
