    摘要: A mechanism is provided to resolve the Iub transport network congestion efficiently for HSDPA by dynamic adjustment of the transmit window of the RLC. The RLC protocol is extended with congestion control functionality. The Iub TN and Uu congestion detection method in the Node-B signals the congestion to the RNC, and this congestion indication is used by RLC to react on the congestion situation. In the RNC, the transmission window of the RLC is adjusted to control the flow rate. When congestion is detected, the RLC transmission window size is decreased. When there is no congestion, then the RLC transmission window size is increased automatically. Different types of congestion are distinguished and are handled in different ways. Alternatively, congestion control is achieved without any modification in the RLC layer from the existing standard. Here, RLC STATUS PDUs are used to change the RLC transmission window size.

    摘要: The present invention is related to a method, base station (RBS) and computer program for quickly recovering from a detected congestion over the air interface. First the current bitrate at the which the air interface congestion has been detected is stored as a new reference bitrate. Thereafter, the base station (RBS) requests a reduction of the bitrate associated with the air interface. When the congestion condition has subsided the base station (RBS) requests a boost of the bitrate associated with the air interface up to the stored new reference bitrate. When finally the new reference bitrate has been reached, the base station (RBS) requests a linear increase of the bitrate associated with the air interface.

    摘要: A network includes a first node and a second node and data frames are transmitted from the first node to the second node. Each of the data frames carry information belonging to one of a plurality of data flows. In a flow control unit (125) there is an estimate or measure determining unit (1201) for determining for each of the data flows, at the ends of first time periods having a predetermined first length, an estimate of or a measure representing the total number of received data frames that have been faulty during the first time period. A reference calculating unit (1101) is connected to the estimate or measure determining unit for calculating, based on the determined estimate or measure, a bandwidth capacity reference value determining the currently maximum allowable bandwidth for transmission from the data transmitting node to the data receiving node. 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.
