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.

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.

摘要： The technology in this application determines the throughput over a data communication substantially as experienced by a user receiving the data. The determined throughput is substantially independent of the total amount of data transferred over the connection. This "active" throughput measure is divided into two parts to provide two performance measures: transfer throughput and latency. Latency corresponds to a time period needed to accomplish one or more functions associated with the data connection, like setting up and taking down the connection, during which payload type data to be transferred to an end user is not transferred. By identifying and removing the initial latency from the throughput determination for the data connection, the determined transfer throughput provides a more accurate measure of the throughput actually experienced by the end user.
摘要翻译：该应用中的技术基本上如用户接收数据所经历的那样确定数据通信的吞吐量。确定的吞吐量基本上与通过连接传送的数据的总量无关。这种“主动”吞吐量度量分为两部分，以提供两种性能测量：传输吞吐量和延迟。延迟对应于完成与数据连接相关联的一个或多个功能所需的时间段，例如设置和取消连接，在此期间传送到最终用户的有效载荷类型数据不被传送。通过从数据连接的吞吐量确定中识别和消除初始等待时间，所确定的传送吞吐量提供对最终用户实际经历的吞吐量的更精确的测量。

摘要： A method and apparatus for enabling service aware congestion control of PS (Packet Switched) data to be performed in a communication network. In the communication network PS data is communicated between a core network of the communication network and one or more User Equipments, UE, via the communication network node. Each UE is associated to the core network by one or more PS connections, and each of the PS connections is applied by the UE for a respective PS data service. When performing the service aware congestion control, information related to a respective PS data service is obtained, andpriority information is provided to a resource manager arranged in the communication network. The priority information is based on the information related to the respective PS data service for a plurality of the PS connections. The resource manager is then enabled to perform congestion control of the PS connections based on the priority information. By determining for which PS data services the PS connections are currently applied, and prioritise the PS connections accordingly, the communication network node may reallocate RAN communication resources to higher prioritised PS data services from less prioritised PS data services. Thereby, a more flexible and effective use of available RAN communication resources may be achieved. (Figure 2)
摘要翻译：一种能够在通信网络中执行的PS（分组交换）数据的服务感知拥塞控制的方法和装置。在通信网络中，通过通信网络节点在通信网络的核心网络和一个或多个用户设备UE之间传送PS数据。每个UE通过一个或多个PS连接与核心网络相关联，并且每个PS连接由UE应用于相应的PS数据服务。当执行服务感知拥塞控制时，获得与各个PS数据业务相关的信息，并且优先级信息被提供给布置在通信网络中的资源管理器。优先级信息基于与多个PS连接的各个PS数据服务有关的信息。然后，资源管理器能够基于优先级信息来执行PS连接的拥塞控制。通过确定PS连接当前被应用于哪个PS数据服务，并且相应地优先考虑PS连接，通信网络节点可以从较少优先级的PS数据服务将RAN通信资源重新分配给较高优先级的PS数据服务。因此，可以实现对可用的RAN通信资源的更灵活和有效的使用。（图2）

摘要： The invention deals with the adjustment of the nominal target error rate for transmission of data from a priority queue to a new predetermined target error rate depending on the state of the priority queue. Usually, the adjustment to the new predetermined target error rate will be to a predefined lower target error rate based on states of the priority queue, such as amount of data in the priority queue, time passed since the latest transmission of data from the priority queue, whether the amount of data in the priority queue will fit into one transport block, whether the data unit to be transmitted for the priority queue is the first or last data unit in the priority queue and may also be based on the type of data stored in the priority queue. There may be more than one such priority queue.

摘要： Recovery control is provided for recovering data packet flow control between a network node (14) and a radio base station (18) over a radio network interface (2). The base station communicates with at least one user equipment, UE, (10) over a radio interface (3) and measures information relating to a data transmission rate over the radio interface and an amount of a downlink packet queue (22) in the base station associated with the UE communication. In one embodiment, the base station sends at least some of the measurement information to the network node. A process controller (52, 40, 84) in the network node processes the measurement information to determine a desired amount to be stored in the downlink packet queue. The process controller determines a commanded bit rate to transmit data from the network node to the downlink packet queue based on the determined desired amount and transmits data to the radio base station in accordance with the commanded bit rate.
