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.

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.
