Abstract:
A mobile station, comprising:a radio unit (73) for transceiving data over an air interface at a certain transmission rate, a data interface unit (75) for transceiving data to and from the radio unit, and a control unit (71) for controlling the operation of the radio unit and the interface unit; characterized by: said control unit (71) being adapted to monitor a property of a data flow through the interface unit (75) for deriving a reference value for the monitored property of the data flow; said control unit (71) being provided with at least one threshold value (T1) for the monitored property; said control unit (71) being adapted to compare the derived reference value with the threshold value (T1), and being adapted, as a response to the comparison giving a certain relation of said reference number and said threshold value, to initiate a request for addition or reduction of reserved radio resources for modifying the transmission rate.
