Abstract
The invention refers to a method for improved congestion control in a wireless mobile system where a high speed packet data access (HSDPA) between a node and a number of mobile stations (MS) have been established by dedicating a high speed physical downlink shared channel (HS-PDSCH) to all mobile stations (MS) and one associated dedicated channel (A-DPCH) per each mobile station (MS). The method comprises the steps of; CON-in case of congestion, detecting the amount of download data still to be downloaded by each of the mobile stations (MS) and, -based on the amount of download data still to be downloaded, releasing the associated dedicated channel (A-DPCH) for one or more first mobile stations (MS) having an amount of data above a predetermined threshold level.
