Abstract:
1. Radio-transmission system with a plurality of processing layers for the transmission of data packets between different radio appliances in a radio channel comprising: circuitry configured to provide, a first functional unit in a physical radio-transmission layer, which analyzes the radio channel and determines the quality of the radio channel (QoC); a second functional unit in a data back-up layer, which controls access to the radio channel dependent upon the current quality (QoC) of the radio channel and the priority of the data packets to be transmitted according to the quality (QoS) of the service realized by the data packets; a third functional unit in a switching layer, which controls the switching of the data packets; and a management unit, which releases the data packets for switching by the third functional unit only if the quality (QoS) of the service realized by the data packets corresponds sufficiently with the quality (QoC) of the radio channel determined in the first functional unit, wherein the management unit is connected via a an interface to a fourth functional unit in a transport layer, and wherein the management unit determines a transport protocol on the basis of the quality (QoS) of the service realized by the data packets and the quality (QoC) of the radio channel determined in the first functional unit and controls the fourth functional unit in order to convert the data packets into the corresponding transport protocol.
