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 and network node for dynamically controlling throughput over an air interface between a mobile terminal and a radio telecommunication system. The method detects a type of service being utilized by the mobile terminal, and dynamically selects a target delay for the traffic between a base station and the mobile terminal. The detecting may be done by a Deep Packet Inspection (DPI) engine implemented in a core network node such as a Gateway GPRS Support Node (GGSN). When the mobile terminal activates a delay-sensitive service, the target delay is dynamically changed to a smaller value to reduce latency. When the mobile terminal deactivates all delay-sensitive services, the target delay is dynamically changed to a larger value to increase throughput.

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.
