摘要： A radio access network node (28) which provides High Speed Downlink Packet Access (HSDPA) comprises one or more priority queues (50) and a flow controller (60). The priority queue (50) stores data which is to be sent on a High Speed Downlink Shared Channel (HS-DSCH) over an air interface (32) to a mobile terminal (30). The data is received in the priority queue over an interface with a superior node in accordance with a capacity allocation determined by the radio access node. The flow controller (60) measures actual utilization of the capacity allocation for the priority queue and uses the actual utilization of the capacity allocation to adjust the capacity allocation.

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). In one example mode of operation, the pre-knowledge sending of the HS-DSCH data frames to the target radio base station is performed with a presumptive capacity allocation for the target cell. A first type of presumptive capacity allocation is an initial capacity allocation sent from the target radio base station to the control node and configured to evoke transmission of a first HS-DSCH data frame from the control node to the target radio base station. A second type of presumptive capacity allocation is a cell change capacity allocation which is sent to the control node from the target radio base station upon receipt by the target radio base station of the first HS-DSCH data frame evoked by the initial capacity allocation. In an example implementation, the presumptive capacity allocation is related to an (e.g., estimated or approximate) acceptable carrier quality indicator value at a cell border for the cell change.

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 method for detecting congestion in a transport network is provided. The congestion detection utilizes flow control including relative bitrate. The method comprises counting the number of detected frame loss events for a flow. The method further comprises determining if the number of detected frame losses is greater than or equal to a corresponding threshold, wherein the threshold used is an individual threshold for the flow set taking into account relative bitrate weights of the flow, and detecting transport network congestion for the flow when the number of detected frame losses is greater than or equal to the corresponding threshold.

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： 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： A method and system are disclosed for improving the Operations and Maintenance (OAM) of base stations (102, 104, 106, 108) in a mobile communication system (100), whereby an OAM connection can be made with a base station (102, 104, 106, 108) over a radio air interface (214) so that failures that occur in the base station can be detected, analyzed and corrected (if possible), even if the normal transmission link (103, 105, 107, 109) to the base station (102, 104, 106, 108) has gone down or become otherwise inoperable. For one embodiment, a Test Mobile Station (TMS) (116) is co-located with or located nearby a radio base station (104) (RBS) (104). The TMS (116) monitors the RBS' operations, and can provide base station operability information to a Radio Network Controller (RNC)(110) and/or OAM unit via an existing radio air interface (214). For a second embodiment, a TMS (116, 120, 124, 128) for remote control of OAM (112) functions is co-located or located nearby a radio base station's mast-mounted equipment.

摘要： A radio base station (104) is described herein that measures a round-trip-time (RTT) which is the time it takes an uplink (UL) control frame (109a) to travel to a radio network controller (102)) and a downlink (DL) control frame (109b) to travel back from the radio network controller (102). If the measured RTT is greater than a predetermined threshold, then the radio base station (104) can correct a problem associated with too long of a RTT by reducing the bit rate of a certain high-speed (HS) user flow or by reducing the maximum bit rate for all of the HS traffic which is going to be sent by the radio network controller (102) over the transport link (106) to the radio base station (104.
