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.

摘要： A telecommunications system and method is disclosed for efficient and flexible usage of bandwidth within a code division multiple access (CDMA) cell. Multiple carriers can be included within a CDMA cell, in which a different number of carriers can be allocated to downlink transmissions and uplink transmissions. In addition, a mobile station (MS) can allocate downlink bandwidth from different carriers to contribute to a Traffic channel, making it possible to form high user bit-rates, e.g., 4 Mbps. A CDMA cell can contain a Primary carrier with all channel types and at least one Secondary carrier with only dedicated channels and optionally power controlled common channels. The Primary carrier has a primary scrambling code and zero or more secondary scrambling codes associated therewith, while the Secondary carrier has one or more secondary scrambling codes associated therewith.

摘要： Methods, systems, and arrangements enable balanced base station transmitter output power levels with respect to a receiving mobile station (115, 315, 335, 355, 375) in a macro-diversity communication by adjusting a base station transmitter output power level responsive to power control command(s) sent by the mobile station (115, 315, 335, 355, 375) and the (current) transmitter output power level of the base station (110, 310, 305, 325, 330, 345, 350, 365, 370). In a fixed adjustment step embodiment, power level convergence is enabled by adjusting (430C, 430F) the transmitter output power level of a given base station (110, 310, 305, 325, 330, 345, 350, 365, 370) by a greater amount (e.g., than the nominal amount) when a power control command orders a power adjustment of the transmitter output power level towards a reference level and by adjusting (430B, 430E) the transmitter output power level by a lesser amount when a power control command orders a power adjustment of the transmitter output power level away from the reference level. A continuous adjustment step embodiment is also disclosed.

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 radio base station (104) is described herein that uses a delay reference timing (DRT) extension (402) located within a received high-speed downlink shared channel (HS-DSCH) data frame (110) to detect a buffering delay that is caused by large buffer build ups in transport nodes (112 and 114) that are located on a transport link (106) between a radio network controller (102) and the radio base station (104). In addition, the radio base station (104) can correct a problem if the detected buffering delay is too long 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).

摘要： The invention relates to a method and device (14) of controlling bit rate of a terminal (11, 12, 13) included in a group of terminals. To this end, a method is provided comprising the steps of acquiring a predetermined QoS parameter for the terminal, which parameter stipulates target QoS to be given to the terminal relative to other terminals in the group, and acquiring either one or both of (a) at least one measure of a channel condition of the terminal and (b) at least one capacity measure of the terminal. Further, the method comprises the step of controlling the bit rate of the terminal on the basis of a reference weighting factor created by a combination of the acquired predetermined QoS parameter, the acquired at least one measure of a channel condition of the terminal and/or the acquired at least one capacity measure of the terminal.

摘要： 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.

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.
