Abstract
A radio access network node (28) which provides High Speed Downlink Packet Access (HSDPA) comprises one or more priority queues (50i) and a flow controller (60). The priority queue (50) stores data which is to be sent on a High Speed Downlink Shared Channel (HS-DSCH) over an air interface (32) to a mobile terminal (30). The data is received in the priority queue over an interface with a superior node in accordance with a capacity allocation determined by the radio access node. The flow controller (60) measures actual utilization of the capacity allocation for the priority queue and uses the actual utilization of the capacity allocation to adjust the capacity allocation.
