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. Acurrent 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： A method is provided of transporting data packets over a telecommunications transport network. The data packets are carried by a plurality of bearers, each carrying data packets that relate to different ones of a plurality of services. In the method bandwidth profiling is applied to the data packets of each bearer, independently of the other bearers, to identify and mark the data packets of each of the bearers that are conformant with a predetermined maximum information rate for the bearer. The data packets are forwarded for transport through the transport network, wherein, if there is insufficient bandwidth available in the transport network to transport all data packets, data packets not identified by the profiling as being conformant are discarded, so as not to be transported through the transport network.

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： 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.
摘要翻译：在一个方面，本发明有利地在调整用户的最大（可调度）上行链路比特率方面提供比从用于向这些用户进行预定的上行链路许可的定义的许可表直接可用的更大的粒度。作为非限制性示例，WCDMA网络中的节点B中的EUL调度器在给定时间间隔内计算一个或多个用户所需的“有效”比特率，并且从授权表中确定调度许可的模式该间隔以产生期望的有效比特率。该功能使得EUL调度器能够对多个用户的聚合上行链路数据速率进行相对精细的分数调整，从而允许更精确地降低这些用户的聚合上行链路数据速率。 EUL调度器使得这些更精确的调整，例如响应于NodeB与其支持的RNC之间的回程连接的拥塞的指示。为了获得更好的比特率控制粒度，在一个或多个用户的HARQ进程中也可以使用授权变动。

摘要： A mechanism is provided to resolve the Iub transport network congestion efficiently for HSDPA by dynamic adjustment of the transmit window of the RLC. The RLC protocol is extended with congestion control functionality. The Iub TN and Uu congestion detection method in the Node-B (120) signals the congestion to the RNC (110), and this congestion indication is used by RLC to react on the congestion situation. In the RNC (110), the transmission window of the RLC is adjusted to control the flow rate. When congestion is detected, the RLC transmission window size is decreased. When there is no congestion, then the RLC transmission window size is increased automatically. Different types of congestion are distinguished and are handled in different ways. Alternatively, congestion control is achieved without any modification in the RLC layer from the existing standard. Here, RLC STATUS PDUs are used to change the RLC transmission window size.

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 of prioritising packets for delivery over a transport network interconnecting nodes of a mobile network, where a guaranteed minimum information rate over the transport network is specified for the mobile network. The method comprises, for each bearer to be injected into the transport network from the mobile network, specifying a bearer information rate and marking packets up to that rate as conformant with the bearer information rate and marking packets exceeding that rate as non-conformant with the bearer information rate. A plurality of traffic type streams from the mobile network are converged, each traffic type stream comprising a plurality of bearers. Packets of the converged traffic type streams are inspected to identify packets marked as conformant and non-conformant, and re-marking non-conformant packets, or at least a fraction of non-conformant packets, as conformant if the converged rate of conformant packets is less than said minimum information rate. The transport network prioritises the delivery of packets marked as conformant over those packets marked as non-conformant.
