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： In general, it is proposed to define a new expiry mechanism for a data file being received at the client. In the following it is proposed that the expiry time on the receiver side should be "shortly" after a possible reception of all packets. It is proposed that the receiver should know as precisely as possible that no additional packets for that data file are expected anymore. As soon as the receiver can safely regard the reception of the file, the receiver could either move on to the next segment (delay optimization) or try to make use of the received information.
摘要翻译：一般来说，建议为在客户端接收到的数据文件定义一个新的到期机制。在下文中，提出接收机端的到期时间应该在可能接收到所有分组之后“短”。建议接收机应尽可能精确地知道，不再需要该数据文件的附加数据包。一旦接收机可以安全地考虑文件的接收，则接收机可以移动到下一个段（延迟优化）或尝试利用所接收的信息。

摘要： A technique of operating a network node in a media distribution network in which media data are transmitted in media bursts to a buffer of a media client is described. Each media burst is followed by an idle period in which no media data are transmitted. A method aspect of this technique comprises determining a fill level of the media client buffer, and generating a media burst. Media burst generation includes adjusting at least one of a media data volume of the media burst and a duration of an idle period following the media burst dependent on the fill level of the media client buffer.

摘要： The invention relates to techniques for providing media content in a broadcast scenario to a streaming player, like a DASH player. In order to compensate a problem of variable segment sizes, which leads to the variation in the reception intervals of the media segments, it is proposed to estimate the segment availability time for requesting sub- sequent media segments. The estimation considers a correction value compensating the variation in a reception intervals of media segments so that the streaming player receives the media segments at a constant time interval, namely at the segment duration. In one embodiment it is proposed to use the value of the minBufferTime from the MPDfile, The min BufferTime is namely an indication of the varying segment size of the media content. The minBufferTime indicates the time needed for buffering a media content before starting playing out said media content. The estimation may be done on the client, user equipment UEor on the server device side. If the UE is correcting the segment availability, then the UE uses the time of a first segment reception as base. If the serveris correcting the segment availability then it uses the original segment avail- ability time at the server as base plus end-to-end delay.
摘要翻译：本发明涉及用于向播放器（如DASH播放器）向广播场景提供媒体内容的技术。为了补偿导致媒体段的接收间隔的变化的可变段大小的问题，建议估计用于请求后续介质段的段可用时间。该估计考虑补偿媒体片段的接收间隔中的变化的校正值，使得流播放器以恒定时间间隔即片段持续时间接收媒体片段。在一个实施例中，建议使用来自MPD文件的minBufferTime的值。最小缓冲时间即为媒体内容的变化段大小的指示。 minBufferTime指示在开始播放所述媒体内容之前缓冲媒体内容所需的时间。估计可以在客户端，用户设备UE或服务器设备侧进行。如果UE正在校正段可用性，则UE将第一段接收的时间用作基地址。如果服务器正在纠正段可用性，那么它将使用服务器上的原始段可用时间作为基础加上端到端延迟。

摘要： A method (400) of controlling resource usage of adaptive streaming sessions for transmission via a Radio Access Network (RAN) is provided. The method comprises identifying (401) at least one adaptive streaming session, determining (402) available bitrates for the identified adaptive streaming sessions, determining (403) a resource allocation of the RAN, determining (404) a target bitrate for each of the identified adaptive streaming sessions, and throttling (405) each of the identified adaptive streaming sessions having a current bitrate which is larger than their respective target bitrate. The respective target bitrates are determined (404) based on the available bitrates and the current resource allocation of the RAN. In this way, an improved distribution of shared air interface resources of the RAN may be achieved. Further, a network node for controlling resource usage of adaptive streaming sessions for transmission via a RAN is provided.
