摘要： For streaming data in a mobile communication network, a descriptive file (100) of a stream (200) is provided. The descriptive file (100) comprises a list (110) of delivery source identifiers, e.g. URIs, for unicast delivery of data segments (210) of the stream. A broadcast indicator (120) is selectively added to the descriptive file (100) so as to indicate whether broadcast delivery of the data segments (210) is available. Adding the broadcast indicator (120) and initiating the broadcast delivery may be accomplished on the basis of a popularity of the stream.

摘要： The invention relates to a mobile telecommunication device (22) comprising: a receiver (40) for receiving content data via a mobile telecommunication network; a play-out buffer (41) for holding downloaded but yet un-played content data; a media reader (42) for reading content data at a media rate from the play-out buffer and for sending content to a display or speaker for rendering; a segment request controller (46) for sending media segment requests to a remote server; a buffer fill monitor (45) for checking a fill level of the play-out buffer, continuously or at least at the end of a media segment download. The segment request controller (46) is configured switch between a state of continuously requesting media segments and a state of not requesting any media segments. This switching is depending on the fill level. By restricting the download of segments, more and longer idle period are created which increases the chance that the radio state is switched down, so as to save battery and resources.

摘要： A system, method, and media edge proxy, MEP, (17) for providing media data such as Internet Protocol Television, IPTV, or Internet radio channels to a media client (12). The MEP obtains the media data from a media server (18) 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 (27), 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： A converter node 27 of an Internet Protocol Television (IPTV) Network 20 comprises a first port 32 for communicating with a receiver 23 (for example a set top box), and a second port 28 for communicating with a video headed end 25 (for example a source of IP Multicast traffic. The converter node also comprises a converting unit 31. In response to receiving, via the first port 32, a request from the receiver 23 to join an internet protocol multicast group (e.g. tune-in to an IPTV channel), the converting unit 31 of the converter node 27 is configured to convert IP Multicast traffic 29 received from the video headed end 25 via the second port 28 into IP Unicast traffic 33 (i.e. personalised traffic), which is forwarded to the receiver 23 via the first port 32.

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 neighboring 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 teaches a media container file comprising media data organized into media source blocks. Forward error correction (FEC) redundancy data is pre-calculated for the different source blocks and organized into the container file as different FEC reservoirs. The container file also comprises meta data providing an association between the media source blocks and the respective FEC reservoirs. The container file can be employed by a media server in a media session for compiling media data packets to be transmitted to requesting clients without the need of extensive data processing and FEC calculation.

摘要： The invention provides a solution for performing multicast within a telecommunication network. The basic idea is to introduce multicast transmission for parts of a network that is basically point-to-point oriented. This is done by creating transport multicast groups TLMG to transport data between network entities. The idea is to have a TLMG going to a node being close to the user. In one embodiment of the invention one TLMG is established between the SGSNs and RNCs and a second one between the GGSN and SGSNs. From the RNC the data is sent via a radio bearer to a user.

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.
