摘要： The invention relates to a method for efficiently providing a bidirectional multicast service (e.g. IMS) to a user equipment (105), located in a radio cell, controlled by a control entity (104). For the downlink data of the bidirectional service a downlink multicast service (e.g. MBMS) is utilized. In case the control entity (e.g. RNC) decides for a point-to-point radio link to the UE, the bidirectional service is notified and system resources, established for the bidirectional service are utilized for providing the bidirectional service downlink data. This includes radio resources in the radio access network and may include connections in the core network. Optionally, the downlink multicast service may be de-activated for the specific mobile terminal, but the system resources already established may be maintained. The invention further relates to a network entity in the CN or in the RAN for configuring system resources and for forwarding the multicast service data to the UE.
摘要翻译：本发明涉及一种用于向由控制实体（104）控制的位于无线电小区中的用户设备（105）有效提供双向多播服务（例如IMS）的方法。对于双向服务的下行链路数据，使用下行链路多播服务（例如MBMS）。在控制实体（例如RNC）确定到UE的点对点无线链路的情况下，通知双向业务，为双向业务建立的系统资源用于提供双向业务下行数据。这包括无线电接入网络中的无线电资源，并且可以包括核心网络中的连接。可选地，可以针对特定移动终端去激活下行链路多播服务，但是可以维护已建立的系统资源。本发明还涉及CN或RAN中的网络实体，用于配置系统资源并将组播业务数据转发给UE。

摘要： The invention relates to group communication services, i.e. communication services involving two or more users (or service participants). The invention provides a method for distributing multicast data of a multicast service to different domains and a method for distributing multicast data to service participants in a domain. Further, the invention relates to a control node and system implementing the respective methods. To improve resource utilization when providing a multicast service, including inter alia PoC services, to service participants the invention provides mechanisms to avoid unnecessary multiplication of multicast data in the distribution tree for multicast services with service participants of different domains. For this purpose the controlling node that is initiating the multicast service upon request determined to which domains the multicast data is to be provided and only forwards the multicast data on a per-domain basis. Another aspect of the invention is the avoidance of unnecessary duplications of multicast data within individual domains.

摘要： The invention relates to a method for filtering and a network entity of the core network or the radio access network of a mobile communication system filtering streams belonging to a single user service. The packet streams, each being transported by a bearer service, provide a multicast or broadcast service and is delivered from a service center via the network entity to a mobile terminal. The network entity comprises a service manager providing a quality-of-service management function. The invention further relates to a communication system comprising the network entity. To provide an adaptive multimedia broadcast/multicast service QoS architecture that is scalable to a great number of users, the invention suggests providing the service in form of a packet streams, each being provided via a single bearer service, and equipping nodes within the distribution tree of the service filter capability allowing to (de)register bearer services providing the service based on the downlink quality-of-service constraints obtained from a service manager.

摘要： The invention relates to a method and apparatus for transmitting and receiving video data arranged in data frames forming a data stream. Each frame has assigned a priority level. Once a data frame has been transmitted through an unreliable channel and has not been received at the receiver, the priority level of the missing data frame is compared with a priority threshold value, and is then retransmitted if its priority level is greater than the priority threshold value. The retransmission decision is performed either at the transmitting or at the receiving side. According to a preferred embodiment, the priority level of any data frame to be transmitted is compared with the threshold value. The priority decision may involve the calculation of the priority threshold value based on a measurement of the available channel bandwidths and eventually on the bit rate of previously sent frames. The retransmission decision further may include an estimation of the arrival time of the data frame to be retransmitted.

摘要： A method of transmitting data packets, in particular of real-time or near-real-time data over internet protocol (IP) networks using a real-time protocol (RTP) for media data products and a real-time control protocol (RTCP) for control data packets. Each protocol is allocated a fraction of the available transmission bandwidth. The method comprises the steps of measuring relevant characteristics of the network link, calculating from this measurement an optimized RTCP bandwidth and transmitting control data packets using the optimized RTCP bandwidth.
