The allocation of shared transmission resources are optimised between two or more packet data streams of applications executing in a device in a packet data communications network. The device includes a transmission resource manager function. Each application specifies a range of acceptable values for one or more of the parameters that determine the transmission quality of its data stream, and the transmission resource manager function allocates the available transmission resources to all the data streams in dependence on the range of acceptable values supplied by each application. Preferably, the application supplies for each parameter a range in the form of a target value, which is the preferred value for the application, and a limit value, which is the minimum acceptable value to the application. Transmission resources may be allocated in such a way as to maximise the number of active data streams. May be applied to GPRS and UMTS radio communication systems.
