A device for a radio-communication system, a transmission being carried out in a radio-communication frame using time slots, the time slots representing multiples of a basic bit rate, the device comprising:
- means for providing a supplemental transmission of at least one of packet-oriented data and cell-oriented data;
- and
- means for dynamically assigning a transmission capacity as a function of at least one of a traffic intensity in the transmitted time slots and a number of data packets or cells, the dynamic assignment being an assignment that is changeable during an existing radio link.
A device for a radio-communication system, a transmission being carried out in a radio-communication frame using time slots, the time slots representing multiples of a basic bit rate, the device comprising:
- means for providing a supplemental transmission of at least one of packet-oriented data and cell-oriented data;
- and
- means for dynamically assigning a transmission capacity as a function of at least one of a traffic intensity in the transmitted time slots and a number of data packets or cells, the dynamic assignment being an assignment that is changeable during an existing radio link;
- wherein a module for recording and evaluating the data packets or cells, within a prescribed time period, and for outputting a request signal to increase the transmission capacity when a number of the data packets per time period exceeds a threshold value, is assigned to a radio-communication subscriber.
A device for a radio-communication system, a transmission being carried out in a radio-communication frame using time slots, the time slots representing multiples of a basic bit rate, the device comprising:
