Abstract
A first base station associated with a first radio cell is used to transmit data packets in a second sequence to at least one subscriber station by at least one first radio channel. The subscriber station sorts out the received data packets into a first sequence in an intermediate storage unit and the base station associated with the first radio cell is used to derive and/or represent status information relating to the content of the intermediate storage unit in a status memory unit. Transmission of the data packets is relayed from the first to the second radio cell and data packets are transmitted by a base station associated with the second radio cell to the subscriber station by at least one other radio channel. The status information is transferred from the base station associated with the first radio cell to the base station associated with the second radio cell.
