    摘要： A mobile communication control system, which includes at least one mobile station and at least one base station, includes first through third parts. The first part measures traffic of radio channels in one or both of the above-mentioned at least one mobile station and the above-mentioned at least one base station. The second part measures a communications quality of radio channels in use. The third part determines a transmit power on a transmitting side and an information transmission bit rate on the basis of the traffic of the radio channels in use and information as to whether the transmit power on the transmitting side has reached a maximum transmit power.

    摘要： A timeslot selection method is provided. The timeslot selection method includes the steps of: obtaining a propagation loss; receiving an occupation state and an interference amount of an uplink timeslot; obtaining a desired wave power from the propagation loss; obtaining a ratio between the desired wave power and the propagation loss for the uplink timeslot in which the occupation state is idle; and selecting the transmitting timeslot by using the ratio. In addition, a timeslot assignment method in which there are a plurality of TDD boundaries each of which is a boundary between at least an uplink timeslot and at least a downlink timeslot in a frame is provided. Furthermore, a timeslot assignment method is provided, in which assignment is carried out according to a service class included in a QoS request.

    摘要： A packet transmission method in which packets are transmitted between a base station and a mobile station communicating with the base station includes the steps of: recognizing the size of each of the packets to be transmitted; determining a transmission rate for each packet in accordance with the recognized size of the packet; allocating a radio resource to the transmission of each packet between the base station and the mobile station based on the determined transmission rate; and transmitting each packet between the base station and the mobile station using the allocated radio resource. In the method, a modulation method or a radio resource used for transmitting the packets is determined by calculating a transmission rate in a wireless area according to the size of each packet and a transmission request in the wireless area. The transmission request is recognized by the base station from an upper network when the packets are transmitted downward, while calculated by the base station based on a user request and a transmission state of the upper network when the packets are transmitted upward. Therefore, end-to-end quality of service can be provided.

    摘要： An autonomous zone forming method of autonomously forming a zone which is a service area of a base station in a wireless communication system having the base station is provided. In the method, it is detected that a zone is newly formed around the base station, and a zone which is the service area of the base station is autonomously changed according to a newly formed zone. When determining the zone, receive quality of a signal received from a surrounding base station is used. In addition, a congestion state of a surrounding base station of the base station is detected, and a zone which is the service area of the base station is enlarged to the direction of the surrounding base station according to the congestion state.

    摘要： A mobile communication system includes a plurality of base stations in a communication service area connected to a packet communications network. A mobile station communicates with a second station through the plurality of base stations and the network. The mobile communication system determines a virtual base station group as an aggregation of the plurality of base stations communicating with the mobile station, based on a condition of a radio transmission path between the mobile station and each base station, and combines information received by the plurality of base stations that belong to the virtual base station group at a base station included in the virtual base station group. The network connects the plurality of base stations non-hierarchically and the base station transmits combined information to the second station through the network relative to combined packets having the second station as a destination.
