Abstract: 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 (120) signals the congestion to the RNC (110), and this congestion indication is used by RLC to react on the congestion situation. In the RNC (110), 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.

Abstract: In one aspect, a method and apparatus are disclosed that can provide an efficient and robust HSDPA flow control solution. The RNC (110) can receive information regarding allowed data rate from the Node-B (120) for a data flow in a downlink direction. Based on the received data rate information and optionally based on other predetermined considerations, the RNC (110) adjusts the RLC PDU transmission window size for the data flow. When the RLC PDU transmission window is properly sized, reaction to congestion can be performed quicker relative to the existing Iub flow control.

Abstract: The invention discloses a method (200, 300, 400) for traffic control in a cellular telephony system (100) comprising a number of cells, each cell comprising at least one Radio Base Station, RBS, (170). The system (100) comprises at least one Radio Network Controller, RNC, (110 130 150), for the control of a number of Radio Base stations. The traffic between an RBS and an RNC comprises a number of flows. The invention is intended for the control of flows from the Radio Base Stations to their RNC. The method uses one control function for each flow from each of said Radio Base Stations, and also comprises a congestion detection function (220) which detects the presence or absence of congestion in the traffic from an RBS to an RNC, and which, upon detection of congestion reduces the bit rate of the congested traffic, and in the absence of congestion, increases the bit rate of the previously congested traffic.

Abstract: In one aspect, a mechanism is provided to resolve the Iub transport network congestion in the uplink direction by using the transmission window of the RLC to control the transfer rate of the flow. The RNC (110) detects the Iub TN congestion for the flow in the uplink. The EUL flow control running in the RNC (110) calculates the RLC transmission window size for the UE for the flow and the calculated RLC transmission window size is signaled to the peer RLC entity in the UE (130) through an RLC STATUS PDU.

Abstract: 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. A determining unit (911) 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 (919) 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.

Abstract: A method is disclosed for controlling, according to an additive increase multiplicative decrease (AIMD) principle, the bandwidth sharing among contending traffic flows over a transport network between a radio network controller and a radio base station. According to the method, a relative bit-rate (RBR) is determined (210) for each traffic flow; and the bit-rates of said traffic flows are controlled (220) such that additive increase operations of said AIMD principle depend on the respective RBR of each traffic flow. Embodiments of the invention strive at supporting Gold, Silver and Bronze HSDPA and/or EUL bit-rate subscriptions over a single TN QoS class.

Abstract: The invention discloses a method for detecting and controlling traffic congestion in a wireless telecommunications system (100, 300, 400) comprising at least a first node (130, 330, 430) such as a Radio Base Station, and at least one second node (110, 310, 410) such as a Radio Network Controller, the system also comprising a Transport Network, TN (120, 320, 420), for conveying traffic between said first and second nodes, in which system (100, 300, 400) the traffic can comprise one or more flow. The method comprises the use of one flow control function (315, 415) per each of said flows, said one flow control function (315, 415) comprising a congestion detection and control function. In addition, the congestion detection function acts to reduce the traffic on said flow before the system becomes congested.

Abstract: The present invention proposes a solution in the area of HSDPA flow control. It proposes an improvement to transport network congestion detection and avoidance. The improvement proposes to use a measurement of incoming bitrate to determine the reduction of bitrate after a transport network congestion event. The advantage is that high bitrate reduction is only used when it is necessary; otherwise only small bitrate reduction is used, which results in small oscillation, and consequently higher transport network utilization.

Abstract: 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.

Abstract: Congestion in a radio access network (RAN) associated with transporting uplink information originating from one or more mobile terminals is detected. That detected RAN congestion is reduced using any suitable technique (several examples are described) and may be implemented in one or more nodes in the RAN. One advantageous (but non-limiting) application is to a RAN that supports high speed uplink packet access (HSUPA) and/or one or more enhanced uplink dedicated channels (E-DCHs).

Abstract: A control node (26) of a radio access network participating in a cell change procedure is permitted to begin sending HS-DSCH data frames to a target radio base station (28) even before the control node knows a calculated capacity allocation for the target cell. Such pre-knowledge transmission of HS-DSCH data frames by the control node effectively reduces a control node (e.g., RNC) bitrate transmission gap which otherwise would occur had the control node waited to send the high-speed downlink shared channel (HS-DSCH) data frames after the control node had been informed of the calculated capacity allocation. The control node is permitted to begin sending the HS-DSCH data frames even prior to an activation time (AT), and typically just after a switch time (ST).
