The usage of the transmission resources allocated to applications executing on a device in a packet data communications network are monitored and controlled. An application utilises multiple packet data streams on different physical bearers simultaneously. The amount of data transmitted per unit time by said application on each packet data stream is controlled individually such that data is not transmitted at a rate in excess of the assigned bit rate for each packet data stream. Each packet data stream of said application is assigned an individual bit rate at which data packets can be transmitted, the actual bit rate at which the application offers data packets for transmission on each packet data stream is monitored, and data packets offered for transmission on each packet data stream that would cause the assigned bit rate for said packet data stream to be exceeded, are delayed or discarded. May be applied to Packet Data Protocol (PDP) attributes in a UMTS system. |
