摘要： A radio network entity in charge of outer loop power control for a communication with a mobile radio is informed about erroneous data units, requested retransmissions, and/or data units transmission attempts associated with the data units sent by the mobile radio to the radio network. Another radio network entity, which sends a transmission power control signal to the mobile radio to control the mobile's transmit power level based on a target value, detects errors in data units received from the mobile radio and requests retransmission. Information associated with the requested retransmission is used to generate a revised target value. The target value may be revised by an outer loop power controller node or by an outer loop power controller entity in the same node as an ARQ entity that generates the information about erroneous data units, requested retransmissions, and/or data units transmission attempts associated with the data units sent by the mobile radio to the radio network.

摘要： The invention describes a flow control method to control HS-DSCH data streams over UTRAN Iub and Iur interfaces. Two credit assignment schemes are also described. A radio network node at which the flow control method executes is proposed. Finally a computer program product for execution of the flow control method and the credit assignment schemes is described. The control of separate user data flows is coordinated by Node-B and data transport over the Iub and Iur interfaces is adapted to data transfer over the Uu interface. The main advantage is that buffering can be primarily maintained in SRNC. It is shown that the proposed flow control method can significantly reduce Node-B's buffer level when compared to a scheme where the control of individual data flows is performed independently of each other. It is also shown that the negative impact on the quantity of flowing data is generally minor. (Figure 5)
摘要翻译：本发明描述了一种通过UTRAN Iub和Iur接口来控制HS-DSCH数据流的流控制方法。还描述了两个信用分配方案。提出了流控制方法执行的无线网络节点。最后描述用于执行流控制方法和信用分配方案的计算机程序产品。单独的用户数据流的控制由节点B进行协调，并通过Iub进行数据传输，Iur接口适用于通过Uu接口的数据传输。主要优点是可以在SRNC中主要保持缓冲。结果表明，与单独数据流的控制相互独立执行的方案相比，所提出的流控制方法可以显着降低节点B的缓冲器电平。还表明，流量数据的负面影响通常较小。（图5）

摘要： A method and apparatus for reducing handover interruptions when a mobile device executes handover including a random access procedure is described herein. When handover is desirable, a time offset associated with a random access opportunity is determined. The time offset relates the timing of the next random access opportunity to the frame timing of a target access point. Based on the time offset, a network element, e.g., the mobile device, a serving access point, or a mobility management entity, determines a handover start time. Handover is executed at the determined start time to generally align the beginning of the handover execution with the beginning of the next random access opportunity, and therefore, to reduce handover interruption.

摘要： According to the invention data in a number of logical downlink channels (PCCH, CCCH, BCCH, CTCH, MCCH, MSCH and MTCH) intended for one or more mobile terminals are received in a first mapping unit (10), where at least a first High Speed Radio Network Temporary identity is allocated to these logical downlink channels addressing a group of mobile terminals for allowing transmission of channel data for reception by mobile terminals. A mobile terminal then reads, from a Broadcast Control Channel, necessary information including a High Speed Radio Network Temporary identity allocated to at least one logical downlink channel, where at least said first identity exists among possible identities. It then listens to a high speed shared control channel for the read identity. In case it detects the identity, the terminal follows a scheduling command, receives data on a high-speed downlink shared channel (HS-DCH) and processes said data.

摘要： The present invention relates to a system, a Midcom Agent, a method for re-establishing context and a computer program product for performing the steps of said method. In a multi-domain, multi-access IP network there is a need for a method to re-establish context associated with a flow when the end-to-end path changes. The path change is typically due to mobility, but can also be caused by access re-selection (which can be performed for a stationary mobile node as well). Therefore, a method is provided in which the context is moved from one middlebox to at least one selected middlebox via a Midcom Agent. An advantage with the present invention is that it facilitates the transfer of context information from a set of middleboxes to another set of middleboxes. Each set may contain diverse types of such middleboxes.
摘要翻译：本发明涉及一种系统，中间件代理，重建上下文的方法以及用于执行所述方法的步骤的计算机程序产品。在多域多域IP网络中，当端到端路径改变时，需要一种重新建立与流相关联的上下文的方法。路径变化通常是由于移动性而引起的，但是也可以由访问重选（也可以针对固定移动节点执行）引起。因此，提供了一种方法，其中上下文经由Midcom Agent从一个中间框移动到至少一个所选中间框。本发明的优点在于它有助于将上下文信息从一组中间盒传送到另一组中间盒。每组可能包含不同类型的这种中间盒。

摘要： The present invention relates to a radio communication system supporting macrodiversity. The problem address is the complexity of the macrodiversity links and the difficulties in synchronisation that may occur in the retransmission schemes during macrodiversity mode. The problem is solved by a first step of setting up a single communication link instead of the macrodiversity link. The first step though introduces a new problem of increased uplink interference in the base stations 13b that do not support macrodiversity link and that should have done so if macrodiversity mode was used. The second step of the solution is to cancel interference in the base stations 13b no more supporting the macrodiversity links. For the interference cancelling the no more macrodiversity base stations 13b are informed on the spreading code used by the mobile station transmission which transmissions is to be cancelled.

摘要： The present invention relates to broadcast and/or multicast services in mobile communication networks. Control (105) and user (107’, 107’’) planes for services directed to a user (50A-C) in a multicast group (60) are allowed to be separated from each other. At least two user equipments (50A-C) (belonging to the same multicast group) receives service data over a common user plane (107’) over an Iu interface (17). In cases where user equipment (50C) is controlled by a SRNC (22B) different from the CRNC (22A), a radio network subsystem application protocol is extended by procedures communicating service information from the SRNC (22B) to the CRNC (22A). The control plane (105) of such a user equipment (50C) can thus have a separate path compared with a common user plane (107’). Preferably, the user plane (107’) is arranged directly over the Iu interface (17) between a serving support node (12) and the CRNC (22A), while control planes (105) may have a path over the Iur interface (14).
摘要翻译：本发明涉及移动通信网络中的广播和/或多播服务。允许针对多播组（60）中的用户（50A-C）的服务的控制（105）和用户（107'，107“）平面彼此分离。至少两个用户设备（50A-C）（属于相同的组播组）通过Iu接口（17）在公共用户平面（107'）上接收业务数据。在用户设备（50C）由与CRNC（22A）不同的SRNC（22B）控制的情况下，通过从SRNC（22B）向CRNC（22A）传送业务信息的过程来扩展无线网络子系统应用协议。因此，与普通用户平面（107'）相比，这种用户设备（50C）的控制平面（105）可以具有单独的路径。优选地，用户平面（107'）直接布置在服务支持节点（12）和CRNC（22A）之间的Iu接口（17）之上，而控制平面（105）可以具有在Iur接口（14）上的路径）。
