摘要： There is disclosed a manner of providing signaling resiliency in a broadcast communications network, such as an MBMS network, which sends control signals from a gateway node to multiple access nodes via an IP network. For each transmitted control signal message, at least one repetitive control signal message is transmitted, usually multiple times at predetermined intervals. The repetitive signal includes the same session control information as the original session control message, and may also include an indication that it is a repeat control message. It may also include a unique identifier to be read by the access nodes, enabling them discard the packet without further processing if the unique identifier indicates that it has received the same control information previously. In a preferred embodiment, several repeat session control messages are aggregated into a single group message and transmitted, and which may also be provided with a unique identifier to facilitate early discard if appropriate.
摘要翻译：公开了一种在诸如MBMS网络的广播通信网络中提供信令弹性的方式，该网络通过IP网络将控制信号从网关节点发送到多个接入节点。对于每个发送的控制信号消息，通常以预定的间隔多次发送至少一个重复控制信号消息。重复信号包括与原始会话控制消息相同的会话控制信息，并且还可以包括它是重复控制消息的指示。它还可以包括由接入节点读取的唯一标识符，使得如果唯一标识符指示其先前已经接收到相同的控制信息，则它们丢弃该分组而无需进一步处理。在一个优选实施例中，几个重复会话控制消息被聚合成单个群组消息并被发送，并且其还可以被提供有唯一标识符以便于在适当的时候提前丢弃。

摘要： The present invention proposes a solution for providing multicast/broadcast service to users roaming between different operational domains. In particular it is proposed to provide means enabling the user to contact a home multicast/broadcast server. Said means might be a request being triggered by the user. Said request includes a network identifier identifying the visited operational domain, which is provided to the multicast/broadcast server. The latter decides on a provision method for providing the at least one multicast/broadcast service to the user in the visited operational domain considering rules for a provision of multicast/broadcast services in the visited operational domain and the request triggered by the user. Further the multicast/broadcast server determines a second parameter set for accessing the at least one multicast/broadcast service in the visited operational domain according to the provision method and informs the user about the second parameter set.

摘要： The disclosure relates to a technique for transporting content data to a plurality of mobile clients in a network. Among others, a method embodiment for controlling bearer selection by the mobile client in the network having a plurality of access areas is presented. Each access area provides for a transmission of the content data at least one of a point-to-multipoint-type bearer (PTM-type bearer) and a point-to-point-type bearer (PTP-type bearer). The method comprises the step of receiving information regarding a local bearer topology (LBT). The LBT comprises at least two neighbouring access areas including an access area of the mobile client. The LBT information indicates for each access area of the LBT an availability or unavailability of at least one bearer of at least one bearer type. The method further comprises the step of performing bearer selection based on the LBT information.

摘要： The invention provides a solution for switching between channels belonging to one on-demand multi-channel streaming session. An aggregation procedure for aggregating of a number of session descriptions parameters corresponding to a multitude of channels into one single session description is proposed. Further each channel is described by a mandatory unique identifier, which can be referenced in a channel switch request and an optional human readable identifier for display in a title bar or a channel selection menu. A corresponding client application processes the SDP describing the channel bundle and uses the found information for allowing a user to switch to a channel associated with a certain identifier. Signaling of a channel switch request is done preferably via an RTSP SET PARAMETR message or as an alternative out-band via HTTP. A channel switch control unit, which is part of the multi-channel streaming server, receives a multitude of RTP flows and selects one of the flows for forwarding to the client. A switching point determination is a part of the channel switch control unit and determines the next possible point of time for switching to a requested channel. The client application receives time information for the switch point in response to a channel switch request.
摘要翻译：本发明提供了一种用于在属于一个点播多频道流媒体会话的频道之间进行切换的解决方案。提出了一种用于将与多个信道相对应的多个会话描述参数聚合成一个单一会话描述的聚合过程。此外，每个通道由强制性唯一标识符描述，可以在通道切换请求和用于在标题栏或频道选择菜单中显示的可选的人类可读标识符中引用。相应的客户端应用程序处理描述频道束的SDP，并使用找到的信息来允许用户切换到与某个标识符相关联的频道。信道切换请求的信令优选地经由RTSP SET PARAMETR消息或通过HTTP作为替代的带外进行。作为多频道流服务器的一部分的频道切换控制单元接收多个RTP流，并选择一个流以转发给客户端。切换点确定是信道切换控制单元的一部分，并确定切换到所请求的信道的下一个可能的时间点。响应于信道切换请求，客户应用接收切换点的时间信息。

摘要： The idea of the present invention is to postpone the multimedia message delivery to those terminals, who have activated the download feature, but whose users are not immediately interested in watching the content. It is proposed to fragment a multimedia message into a first segment and in the at least one further segment. For the purpose of the present invention a wait timer is defined for postponing the delivery of the at least one further segment. The first segment is sent to all users and the user decides whether he or she wants to see the remaining parts of the message immediately. The first segment includes attributes allowing the user to make a decision and describing parameters of the waiting process.

摘要： A distributed caching and redistribution system, method, and mobile client for caching and redistributing data content in a wireless data network. The system enables mobile clients to cache data content that has been distributed by means of broadcast or multicast, and to redistribute the content from the cache to other users. Using anycast techniques applied to the PLMN, a user who wants to retrieve data that was distributed earlier locates the nearest user that has the content available, and asks the nearest user to forward the content. The "nearest" user may be the closest user, but may also be the optimal user from a Quality of Service (QoS) point of view.

摘要： The invention relates to a method, network node, router, serving node and system for performing multicast in a point-to-point packet-switched oriented telecommunication network. The basic idea is to introduce pre-configured multicast transmission for parts of a network. This is done by creating pre-configured transport multicast group tunnels between a router and a serving node in order to transport the multicast data. Further the present invention describes the possibility of multiplexing of the multicast data streams on a pre-configured transport multicast group tunnel. In particular the invention is applicable for multicasting in networks, like UMTS with a scarce number of resources, in the IP network between the SGSN and GGSN for example on the Gn interface.
