摘要： A method for traffic control in a cellular telephony system (100), each cell comprising at least one node, an RBS (130), for the control of traffic to and from users (150) in the cell. The traffic to each UE (150) can comprise at least one flow, and the method is intended for control of the flows in the traffic to UEs (150) in the system (100), and comprises one control function for each controlled flow to each of said UEs (150). Said control function comprises a congestion avoidance function (240, 440) which detects the presence or absence of congestion in a flow to an UE (150), and which, upon congestion or low utilization of the network reduces the bit rate to the UE (150) in a non-linear fashion, and which, in the absence of congestion, linearly increases the bit rate of the traffic to the UE (150).

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.

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. 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. 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.

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： 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.

摘要： 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).

摘要： 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).

摘要： A functional entity in a digital switch is triplicated in planes operating in parallel. From each plane, a respective passing data flow is spread to parallel planes. A majority vote function receives the data flows of the planes and compares these on a bit level for creating a majority voted data flow. A plane condition sensing function indicates whether links of the planes have meaningful information and synchronism, and emits, as a result, a link condition indicating signal for each plane. A priority select function is connected for receiving the majority voted data flow and the link condition indicating signals. If the link condition indicating signals indicate a fault condition, the priority select function lets the majority voted data flow through as an outgoing data flow from the functional entity. In case a fault condition is indicated in one or more of the link condition indicating signals, the priority select function selects the data flow from one of the planes as an outgoing dataflow based upon an established priority order.
摘要翻译：数字开关中的功能实体在平行运行的平面中重复三次。从每个平面，相应的通过数据流被传播到平行平面。多数投票函数接收平面的数据流，并在一定位上对这些数据进行比较，以创建多数投票数据流。平面条件检测功能指示平面的链接是否具有有意义的信息和同步，并且因此发出每个平面的链接条件指示信号。连接优先选择功能，用于接收多数投票数据流和链接条件指示信号。如果链路状态指示信号指示故障状态，则优先选择功能允许多数投票数据作为来自功能实体的输出数据流。在链路状态指示信号中的一个或多个指示故障状况的情况下，优先级选择功能基于建立的优先级顺序从作为输出数据流的一个平面中选择数据流。

摘要： The embodiments of the present invention relate to a method and a RBS to reduce the RNC load. This is achieved by letting the radio base station identify RRC connection requests and performing RRC connection rejects. In this way, excessive load of RRC requests done by typically Smart Phones can be rejected in a good way by the radio base station and therefore free up capacity in RNC, making it possible for RNC to execute useful traffic to a higher degree.
