摘要： A technique for routing data frames in a telecommunications backhaul network (100) is provided. The telecommunication backhaul network (100) includes a plurality of points and links between the points so that at least two different routes for communicating data frames between a pair of end points is provided. A first end point (102) routes data frames that belong to a communication tunnel between the first end point and second end point (104) on a first route (106), which includes one or more intermediate points (100). At least some of the data frames include a continuity check message. The first end point reroutes data frames belonging to the communication tunnel to a second route that is different from the first route (106), if certain data frames including the continuity check message are lost in the network (100). As to a method aspect of the technique, at least one of the links of the first route are switched to a reduced link capacity. At least a portion of the data frames including the continuity check message are dropped in response to the reduction in link capacity by at least one of the intermediate points (110) of the first route (106).

摘要： The present invention proposes a solution in the area of HSDPA flow control. It proposes an improvement to transport network congestion detection and avoidance. The improvement proposes to use a measurement of incoming bitrate to determine the reduction of bitrate after a transport network congestion event. The advantage is that high bitrate reduction is only used when it is necessary; otherwise only small bitrate reduction is used, which results in small oscillation, and consequently higher transport network utilization.

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.

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 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 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。
