  • Patent number: 5093924
    Abstract: According to a channel assigning method for use in a mobile communication system, a base station selects, in response to a communication connection request, a communication radio channel having an interference wave reception level which is obtained by a measuring unit and satisfies a quality conditions of a communication channel from a plurality of communication radio channels, and transmits information of the communication radio channel to a mobile station as an object of the communication connection request. The mobile station selects the communication radio channel transmitted by the base station, measures an interference wave reception level, and transmits the measurement result to the base station. The base station checks whether the measurement result satisfies the quality conditions of a communication path, and assigns the communication radio channel to the requested communication when the measurement result satisfies the quality conditions of a communication path.

  • Patent number: 5081704
    Abstract: According to a method of arranging radio control channels in mobile communications, for covering a service area with a plurality of radio zones and causing base and mobile stations to exchange signals through the control channels, a broadcasting information transmission portion is assigned to the control channels. This broadcasting information is to be transmitted from the base station to each mobile station to broadcast information associated with radio zones. Information associated with control channel structure in units of base stations is broadcast to the broadcasting information transmission portion. A frequency and a time slot capable of causing the base station and the each mobile station to exchange the signals are determined on the basis of the pieces of broadcasting information and an identical number commonly recognized by the base and mobile stations.
