摘要： A technique for detecting an encoder functionality issue in a media distribution system is presented. In the media distribution system consecutive media segments generated by an encoder are transmitted to a media client, and media descriptions describe expected availability times of media segments for the media client. A method implementation of the technique comprises the step of monitoring an availability time of a media segment compared to an expected availability time of the media segment, wherein the expected availability time is described by, or derived from, a media description. The method further comprises determing whether a deviation of the monitored availability time of the media segment from the expected availability time of the media segment is present, and detecting the encoder functionality issue based on a result of the determination. The encoder functionality issue may comprise one or more of an encoder restart, an encoder malfunction and an encoder time drift.

摘要： The invention proposes a method for receiving a media stream, whereby the media stream is segmented in a plurality of consecutive segments. In the beginning a Manifest file is received, whereby the Manifest file comprises an indication of media segments in a URI template manner and a start index referencing a first segment of said media stream. From the received information within the Manifest file different URIs are assembled, whereby an assembled URI references a segment of said plurality of segments and whereby assembling is based on said indication and an index, whereby the index is calculated on basis of the start index and is incremented by a predetermined value for each consecutive segment. By means of these assembled URIs said segments are received, whereby receivng is based on an identifier allowing for identifying packets of a same segment, whereby said segments are spread over a plurality of packets and each packet of a particular segment comprises said particular identifier, whereby the index is mapped to the identifier. The fetched media segment packets are reassembled to form said media stream. The invention proposes also a method for providing said media streams in the above described manner as well as respective apparatuses allowing for executing the respective method.

摘要： The invention relates to a point-to-multipoint service in a communications network (10) sends a point-to-multipoint notification message (S1) that comprises information on a content transmission (S2). One or more terminals (11-14) reply to the point-to-multipoint notification message or the content transmission with a response message (S3). The network checks from which terminals it received a response message (S4) and compares these terminals with a group of terminals associated with the content transmission (S5). If there are terminals in the group of terminals that did not send a response message, the network will send a point-to-point notification message to them (S7). The point to-point message can be sent in a store-and-forward manner so that terminals temporarily not being able to communicate with the network can receive the message.

摘要： A method of throttling a media stream, comprising a sequence of media segments, for transmission to a client via a radio access network is provided. The method comprises acquiring a media segment, determining a duration of the media segment, transmitting a first part (501′-504′) of the media segment to the client, and transmitting a remaining part (501″-504″) of the media segment to the client. At least one of the parts (501′-504′, 501″-504″) is transmitted during a time interval (&Dgr;t1, &Dgr;t2) which is shorter than a corresponding duration of that part, and transmitting the remaining part is delayed (&Dgr;t0), such that a time interval (&Dgr;ttx) between starting transmitting the first part and transmission of the remaining part being completed is shorter than the duration (&Dgr;tp) of the media segment. Further, a corresponding network node for throttling a media stream is provided. Embodiments of the invention are advantageous in that bursty traffic is generated, resulting in a more efficient usage of air interface resources and reduced power consumption.

摘要： A packet radio data network includes a gateway node (GGSN), at least one serving node (SGSN) coupled to the gateway node, a plurality of radio access nodes (RAN) coupled to the serving node (SGSN), the packet radio network transporting packet data from an external packet data network. The external packet data network includes, an Internet Service Provider (ISP), to mobile stations (MS) wirelessly attached to radio access nodes (RAN). A mobile station (MS) issues a membership report message requesting content of a specific multicast group, whereupon the gateway node (GGSN) issues a multicast context activation message to the serving node (SGSN). The serving node (SGSN) informs the radio access network (RAN) that the mobile station is joining the respective multicast group and sends a multicast activation response to the gateway node (GGSN).

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.
