    摘要： The teachings herein relate to charging for multimedia content, such as Multimedia Broadcast Multicast Service, MBMS, content, that is provided for subscriber consumption through a communication network, such as a wireless communication network. One aspect of the teachings involves the advantageous inclusion of content location information in the context of generating or sending charging-related messages, in association with requested multimedia content. The content location information indicates, for example, whether the requested multimedia content is available for delivery to a subscriber device associated with the request from a data store that internal to the network. This functionality enables differentiated charging as a function of the content location indicated by the content location information included in the charging-related message.

    摘要： A method (300) of a network node for delivering a plurality of simultaneous sessions to a client via a Radio Access Network (RAN) is provided. The method comprises identifying (301) a streaming session, reshaping (302) the streaming session into a sequence of bursts and silent periods, identifying (303) at least one non-time-critical session, reshaping (304) the at least one non-time-critical session into respective sequences of bursts and silent periods, and transmitting (305) the sequences of bursts and silent periods to the RAN. The reshaping (304) of the non-time-critical sessions is performed such that bursts, or silent periods, or both, of the at least one non-time-critical session are aligned with bursts, silent periods, or both, respectively, of the streaming session. By timely aligning the respective bursts and silent periods with each other, the duration of common silent periods may be increased, thereby utilizing air interface resources more efficiently. In addition, a method of a client for receiving a plurality of simultaneous sessions via a RAN is provided.

    摘要： A method, devices, a system, and computer programs for informing multiple mobile terminals (UE10-90) of an emergency event are disclosed. The method comprises the steps of receiving (S300) emergency information associated with the emergency event, establishing (S400) an emergency multimedia capable distribution bearer for a delivery of an emergency service associated with the received emergency information, the emergency multimedia capable distribution bearer being associated with an emergency priority indicator indicating a higher priority for the emergency multimedia capable distribution bearer compared to further communication being not associated with the emergency priority indicator, and delivering (S600) the emergency service via the emergency multimedia capable distribution bearer to the multiple mobile terminals (UE10-90).

    摘要： Presented is a technique for broadcasting content data from a broadcaster (including a multicaster) to a plurality of clients. After a client receives content data from the broadcaster, a plurality of available proxy servers may be contacted, within a specified time interval, for post-processing after the content data broadcast is determined. The client subsequently randomly selects one of the available proxy servers to contact for post-processing after the content data broadcast. The client then randomly selects a delay time within the contact interval for the selected proxy server, at which time the client contacts the selected proxy server at the delay time to initiate post-processing.

    摘要： Techniques for providing media content to an adaptive HTTP streaming player. Upon reception of a HTTP request from the adaptive HTTP streaming player, like a DASH player, requesting the media content, a HTTP entity performs a procedure for determining a representation preference indication of the content being available on a fixed quality interface providing data with fixed data quality, which may provide data being for example received over a broadcast interface or being available in a cache. Said representation preference indication is signaled to the adaptive HTTP streaming player, which is adapted to use the representation preference indication for further requests. The adaptive HTTP streaming player is not aware whether the content is available on a fixed or unicast interface, but is forced with the solution to use the preferred representation being available on the fixed quality interface.

    摘要： A system, method, and media edge proxy, MEP, for providing media data such as Internet Protocol Television, IPTV, or Internet radio channels to a media client. The MEP obtains the media data from a media server utilizing a temporary unicast connection and provides the media data obtained from the server to the media client for an initial time period. Upon determining that the initial time period has expired, the MEP obtains the media data via multicast from a multicast router, provides the media data obtained from the router to the media client, and releases the temporary unicast connection. The invention reduces channel switching delay and thus improves quality-of-experience for the end-user. The invention also avoids excessive IGMP JOIN/LEAVE signaling when a user switches quickly through channels.

    摘要翻译： 用于向媒体客户端提供诸如因特网协议电视，IPTV或因特网无线电频道的媒体数据的系统，方法和媒体边缘代理（MEP）。 MEP使用临时单播连接从媒体服务器获取媒体数据，并将从服务器获得的媒体数据提供给媒体客户端一段初始时间段。 在确定初始时间段到期后，MEP通过组播路由器通过组播获取媒体数据，将从路由器获取的媒体数据提供给媒体客户端，并释放临时单播连接。 本发明减少了通道切换延迟，从而提高了终端用户的体验质量。 当用户快速切换通道时，本发明还可以避免过多的IGMP JOIN / LEAVE信令。
