Abstract:
1. A method of operating a telecommunications node comprising: receiving plural data packets from a source external to the node, the plural data packets including both ordinary packets and a priority packet; storing the plural data packets in a queue structure in order of arrival so that the priority packet is read out of the queue structure before the ordinary packets are read out of the queue structure, thereby expediting output of the priority packet from the node relative to the ordinary packets; wherein the priority packet is included in a HS-DSCH DATA FRAME TYPE 2 frame of a HS-DSCH channel, further comprising: checking values of three spare bits of a fixed header of the frame and a value of a spare bit of a particular packet of the payload of the frame to obtain a priority level for the particular packet, wherein depending on values of the three spare bits of the fixed header the priority level of the particular packet is susceptible of being interpreted to any of the following: all PDUs in the frame are scheduled with priority level low; all PDUs in the frame are scheduled with priority level medium all PDUs in the frame are scheduled with priority level high packets of the frame with a spare payload bit marked with a first predetermined value are scheduled with priority level high and packets of the frame with the spare payload bit marked with a second predetermined value are scheduled with priority level medium; packets of the frame with a spare payload bit marked with a first predetermined value are scheduled with priority level medium and packets of the frame with the spare payload bit marked with a second predetermined value are scheduled with priority level low; packets of the frame with a spare payload bit marked with a first predetermined value are scheduled with priority level high and packets of the frame with the spare payload bit marked with a second predetermined value are scheduled with priority level low.
