摘要： 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.

摘要： 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.

摘要： 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.

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 (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.

摘要： The present invention is generally based on the recognition that the true admissible regions for a multi-service traffic mix can be well approximated by a construction of a non-linear admissible region and one or more linear admissible regions. This makes it possible to accurately control admission of a new connection onto a transport link by checking whether the multi-service traffic mix defined by previously admitted connections together with the new connection is contained within an intersection on a non-linear admissible region and at least one linear admissible region, and admitting the connection if the traffic mix is contained within the intersecton of regions.

摘要： A method of controlling the rate of traffic flow through an Iub interface of a Radio Network Controller is described. The method includes obtaining a licensed rate, which defines the maximum throughput permitted through the Iub interface, at the Radio Network Controller. The rate of traffic flow through the Iub interface and all Iu interfaces of the Radio Network Controller is measured, and the extent to which packet switched traffic flow through the Iub interface exceeds the licensed rate identified. If the packet switched traffic flow through the Iub interface exceeds the licensed rate, packets are dropped from traffic flow through the Iub interface to reduce the traffic flow to the licensed rate.
