    摘要： Methods and systems are described for enabling network-initiated control of streaming of segmented content from a content delivery node to at least one client, said client being configured to access at least part of said segmented content on the basis of a manifest file, wherein a method may comprise: receiving a first manifest file identifying one or more segments and location information for locating one or more content delivery nodes configured to transmit said one or more segments to said at least one client; in response to said reception of said first manifest file, providing channel set-up information; and, establishing at least one streaming control channel between said at least one client and a control channel server function associated with said content delivery node on the basis of said control channel set-up information, said at least one client being configured for receiving at least one manifest file update message via said streaming control channel.

    摘要： A method and a system for managing associated sessions in a network is described, wherein the network comprises a network element configured for managing associated sessions between the network and user equipment.
    The method comprises the steps of providing a composition session identifier for associating sessions in a network; exchanging the composition session identifier between a user equipment and the network element; and associating two or more sessions with the composition session identifier by exchanging the composition session identifier

    摘要： Methods and systems are described for retrieving segmented content originating from two or more content delivery networks. The method may comprise the steps of: retrieving a manifest file template associated with said segmented content comprising one or more pointers to database entries of said first content location database; using said one or more database entries for determining a location of a delivery node in said first or second content delivery network, said delivery node being configured for delivering a segment associated with said database entry; and, generating a manifest file for locating said segmented content by replacing pointers with said determined locations.

    摘要： A method is described for transmitting a multimedia stream from a first terminal and receiving an associated second multimedia stream at a second terminal, wherein the first and second terminal are connected to at least one gateway for enabling the transmission of the first multimedia stream and the receiving of the second associated stream, the method comprises the steps of:-initiating the exchange of first multimedia session information between the first terminal and the gateway, using a first protocol;-providing a trigger to the second terminal to initiate the exchange of second multimedia session information between the second terminal and the gateway, using a second protocol;-in response to the providing of the trigger, the second terminal initiating the exchange of second multimedia session information between the second terminal and the gateway, using a third protocol, the third protocol being different from the second protocol;-transmitting a first multimedia stream from the first terminal and receiving a second associated multimedia stream at the second terminal.
