Packet scheduling of real time packet data

The present invention concerns packet scheduling for a packet data enabled radio communication network. A packet data traffic flow is classified into service class specific traffic queues. The traffic flow comprising one or more data connections of predetermined service classes, at least one of the service classes being real time streaming traffic with a predetermined guaranteed bit rate requirement. A real time streaming service class specific traffic queue is metered to determine whether its bit rate is below or over its guaranteed bit rate requirement, based on which at least one first scheduling weight for the metered real time streaming service class specific traffic queue is determined. At least one second scheduling weight for at least one remaining traffic queue is determined. The traffic queues are scheduled according to the determined scheduling weights.
