摘要： In one aspect, the present invention advantageously provides far greater granularity in adjusting the maximum (schedulable) uplink bit rates of users than is directly available from a defined grant table that is used for making scheduled uplink grants to those users. As a non-limiting example, the EUL scheduler in a NodeB in a WCDMA network calculates the “effective” bit rate desired for one or more users over a given time interval, and determines the pattern of scheduling grants to make from the grant table over that interval, to produce the desired effective bit rate(s). This capability enables the EUL scheduler to make relatively fine fractional adjustments to the aggregate uplink data rate for a plurality of users, thus allowing much more precise reductions in the aggregate uplink data rate of those users. The EUL scheduler makes these more precise adjustments, for example, in response to indications of congestion on the backhaul connection between the NodeB and its supporting RNC. Grant variations also may be used in the HARQ processes of one or more users, for obtaining better bit rate control granularity.

摘要： A technique for operating an RNC of a communication network during a soft handover process of a mobile terminal between a first BS and at least one second BS that are connected to the RNC is provided. A method implementation of the technique comprises receiving, at a MAC protocol layer of the RNC, a first data frame stream from the first BS via a first data path and a second data frame stream from the second BS via a second data path. A relative delay between the data frames of the first and the second data frame stream regarding their arrival at the RNC is determined. At then the MAC protocol layer, data frames of the first and the second data frame stream are then merged into a third data frame stream which is transmitted to a protocol layer above the MAC protocol layer. The merging of the data frames comprises a reordering process of the data frames and wherein, if the relative delay for a data frame exceeds a delay difference reference value, the data frame is transmitted from MAC protocol layer to the protocol layer above the MAC protocol layer without subjecting data frame to the reordering process.

摘要： A technique for operating an RNC of a communication network during a soft handover process of a mobile terminal between a first BS and at least one second BS that are connected to the RNC is provided. A method implementation of the technique comprises receiving, at a MAC protocol layer of the RNC, a first data frame stream from the first BS via a first data path and a second data frame stream from the second BS via a second data path. A relative delay between the data frames of the first and the second data frame stream regarding their arrival at the RNC is determined. The relative delay takes into account different systematic propagation durations from the first BS and the second BS to the RNC. At then the MAC protocol layer, data frames of the first and the second data frame stream are then merged into a third data frame stream which is transmitted to a protocol layer above the MAC protocol layer. The merging of the data frames is carried out in dependence on the relative delay.

摘要： A method and apparatus for packet scheduling over a communication link in a communication network. A data packet scheduler accords scheduling weights to at least two sets of data packets to be transmitted, and the sending of the sets of data packets is scheduled in accordance with the scheduling weights. When it is determined that a change in available bandwidth over the communication link has occurred, the scheduler dynamically adjusts the scheduling weight for each set of data packets on the basis of the available bandwidth. This ensures more efficient resource sharing control and resource guarantees when the available bandwidth changes.

摘要： A method is provided for transporting data packets over a telecommunications transport network. The data packets are carried by a plurality of bearers, and are sent over the transport network from a serving node. Information is received relating to a current capacity of the transport network. A current maximum total information rate for the serving node is dynamically adjusted based on information relating to a current capacity of the transport network. A current maximum information rate for each of the bearers is determined based on the current maximum total information rate. Bandwidth profiling is applied to the data packets of each of the bearers, independently of the other bearers, to identify the data packets of each of the bearers that are conformant with the determined current maximum information rate for the bearer. The data packets are forwarded for transport through the transport network. If there is insufficient bandwidth available in the transport network, data packets not identified by the profiling as being conformant are discarded.

摘要： For implementing handling of congestions in a mobile network, a base station (100), e.g., an evolved Node B, is provided with at least one congestion controller (400, 400′). The congestion controller (400, 400′) operates in relation to data packets which are received from a transport network. The base station (100) then transmits the data packets on at least one radio link, which may be accomplished by using one or more scheduling queues (402) and a radio interface scheduler (410). A bitrate detector (404) measures a bitrate of the received data packets, and a bitrate limit calculator (408) calculates, on the basis of the measured bitrate, a maximum bitrate for transmission of the data packets on the radio link. A congestion detector (406) is used to detect a congestion in the transport network. In response to the detected congestion, the radio interface scheduler (410) schedules transmissions on the at least one radio link to meet the calculated maximum bitrate.

摘要： Congestion is detected in a radio access transport network including one or more radio network controllers each coupled to one or more radio base stations. Multiple data packet flows are each associated with a mobile radio terminal communication, and each flow is controlled in the radio access transport network by a corresponding flow control entity. They are monitored for congestion in the transport network. If a congestion area in the transport network is detected for one of the monitored data packet flows, then a determination is made whether other monitored data packet flows share the detected congestion area. Congestion notification information is communicated to the flow control entities corresponding to the other monitored data packet flows that share the detected congestion area. Based on the congestion notification information, the informed flow control entities may take a flow control action, e.g., to enable fair sharing of communications resources in the transport network.

摘要： A technique for routing one or more service tunnels in a telecommunications backhaul network (110) is provided. The telecommunications backhaul network has a first routing path (132) and a second routing path (134). As to a method aspect of the technique, data of the one or more service tunnels is transmitted on the first routing path (132). A reduction in transmission capacity is detected on the first routing path (134) by means of a first routing path condition. The first routing path condition indicates a state of the first routing path (132). A second routing path condition is determined indicating a state of the second routing path (134) in response to the detected reduction in transmission capacity on the first routing path (132). It is decided upon rerouting one or more of the service tunnels from the first routing path (132) to the second routing path (132) based on both the first routing path condition and the second routing path condition.
