The invention relates to a method and to an ATM (Asynchronous Transfer Mode) system with which bandwidth is dynamically assigned on the common air interface based on connection parameters, actual buffer levels of remote stations (1, 2), the transmission characteristics of the radio range and the strategies for assessing charges. Said bandwidth is assigned in such a way that the transmission volume of ATM-conformal traffic in the uplink direction of wireless point-to-multipoint configurations is optimized while taking these configurations and common boundary conditions into consideration. To this end, the invention provides a central station (3) and at least one remote station (1, 2) which can communicate with the central station (3) over a common air interface (4). Each remote station (1, 2) comprises a buffer (5) for data to be transmitted. Each remote station (1, 2) transmits level data which emulates the state of the buffer (5) of the respective remote station (1, 2) to the central station (3) via a control channel (13). The central station (3) comprises an arithmetic unit (10) which respectively calculates the bandwidth parameters for the individual remote station (1, 2) at least according to the transmitted level data. The central station (3) then assigns the bandwidth parameters to the individual remote stations (1, 2) over the control channel (13'). |
