摘要： The present invention is related to a method, base station (RBS) and computer program for quickly recovering from a detected congestion over the air interface. First the current bitrate at the which the air interface congestion has been detected is stored as a new reference bitrate. Thereafter, the base station (RBS) requests a reduction of the bitrate associated with the air interface. When the congestion condition has subsided the base station (RBS) requests a boost of the bitrate associated with the air interface up to the stored new reference bitrate. When finally the new reference bitrate has been reached, the base station (RBS) requests a linear increase of the bitrate associated with the air interface.

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 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 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.

摘要： A radio base station (RBS) is described herein that detects when a high-speed downlink shared channel (HS-DSCH) data frame (110) is lost after it was transmitted by a radio network controller (RNC) over a transport link (Iub) towards the RBS (104). To accomplish this, the RBS (104) upon receiving a HS-DSCH data frame (110) inspects a frame sequence number (302) located within the received HS-DSCH data frame (110) to determine if the frame sequence number (302) is in sequence with a frame sequence number (302) located within a previously received HS-DSCH data frame (110). If the two frame sequence numbers (302) are not in sequence, then one or more HS-DSCH data frames (110) that were previously transmitted towards the radio base station (104) have been lost. If the radio base station (104) detects to many lost HS-DSCH data frames (110a), then it can correct the problem by reducing the bit rate of a certain 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： Synchronization is effected in a cellular telecommunications network between a timing unit located at control node (e.g., RNC) of the network and a slave timing unit (STU) located at a controlled node (e.g., base station) of the network. Upon determining that a synchronization adjustment of the slave timing unit is necessary, an adjustment signal (e.g., voltage signal) is caused to be input to the oscillator of the slave timing unit in order to change the frequency of the slave's oscillator. Frame counter(s), in communication with the oscillator at the slave timing unit, will thus follow the oscillator continuously with smooth phase adjustments. By avoiding a direct adjustment of the frame counter(s), undesirable phase jumps or steps are avoided that can potentially disturb the air-interface between a base station and mobile station (MS).

摘要： A greater variety of frequency combinations may be utilized in multiple situations, including, by way of example but not limitation, hard handovers, soft handovers (410, 420, 430), macrodiversity, etc. Soft handovers, for example, may be executed between two base stations (BSs) with respect to a mobile station (MS) in which the uplink (UL) and downlink (DL) frequency pairs used to communicate with each base station differ from each other. For instances, only the UL carrier channel, only the DL carrier channel, or both the UL and the DL carrier channels may differ for the respective communications between the MS and the respective Bss. In the first two cases in which only one carrier channel differs, variable duplex distance (VDD) is implemented. In the third case in which both carrier channels differ, constant duplex distance (CDD) is implemented. In another embodiment of the present invention, a hard handover that relies on a VDD implementation is effectuated by changing only one of the UL and the DL carrier channels in the handover process.

摘要： The present invention provides interconnection links between modules in a switch node. A redundant physical link couples the modules and a dual state data packet routing tag is used to identify which link is active. A standard tag received from an application device is converted to the dual state data packet routing tag, after the data leaves the application device so the interconnection link routing is essentially invisible to the application layer.

摘要： A functional entity in a digital switch (102) is triplicated in planes operating in parallel. From each plane a respective passing data flow is spread to each of the planes in parallel therewith. A majority vote function (502) receives the data flows of the own plane and the planes in parallel therewith, and compares these on a bit level for creating a majority voted data flow (DATAMV). A plane condition sensing function (514) indicates whether links of the planes (A, B, C) have meaningful information and synchornism, and emits, as a result, a link condition indicating signal (INSYAI, INSYBI, INSYCI) for each plane forming an indication thereof. A priority select function (506) is connected for receiving the majority voted data flow (DATAMV) 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 (DATAMV) through as an outgoing data flow (DATAOUT) 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 (DATAOUT) based upon an established priority order.
