a plurality of data flows a determining unit determines at periodically repeated times for each of the data flows whether there are more data frames in the first node waiting to be transmitted a capacity allocating unit allocates for each of those data flows for which no data frames have been waiting to be transmitted for a predetermined time period only a small amount of the totally available bitrate or bandwidth for transmission from the first node to the second node it also allocates for each of the remaining data flows for transmission from the first node to the second node a share of the rest of the totally available bitrate or bandwidth so that the sum of the shares for all said remaining data flows is equal to the rest the first node can be a radio network controller and the second node a radio base station the data frames forwarded in an hs dsch over an iub interface application_number US 6490208 A description the general flow of information in a system built according to umts including both a mobile telephony network and some other network for information transmitted from the other network to a user equipment ue in the mobile telephony network using high speed downlink packet access hsdpa in particular the flow between a radio network.
