摘要： A technique for registering a device (10) with a rights issuer system (12) in a digital rights management (DRM) context is described. The device (10) is provided with DRM registration information that is required to use protected content. The DRM registration information is generated from rights issuer information on the one hand and device information on the other hand. The DRM registration technique described herein does not require an interactive registration protocol between a rights issuer server (12) and the device (10). Rather, the DRM registration information may be generated and transferred to the device (10) even if the device (10) is offline, inactive or switched-off.

摘要： In a communication system (SYS) in which a packet data transfer is performed between the network side (NS) and the subscriber terminal side (SS) a physical connection (LC) is maintained during the data packet transfer. An active period detector (AP-DET) detects an active period of data packet generation by evaluating the inter-arrival time (TDIFF) between successively arriving data packets (DP). If the inter-arrival time (TDIFF) falls within a predetermined range a physical connection maintaining device (LC-MAIN) maintains the physical connection (LC) even if a transmitter queue (TR-QUE) temporarily becomes empty. Therefore, within the active period (AP) the transmitter (NS-TR; SS-TR) indicates a non-empty queue. The invention finds particular application in the GPRS/(E)GPRS/GSM environment.

摘要： The invention relates to a method for controlling, by a multipath control entity (100), a remote access from a client device (300) to a server (235) connected to a residential multipath entity, via a multipath connection. The multipath connection includes at least two transmission networks (11, 12) between the client device (300) and the server (235). The method comprises the following steps: First, a session request for an establishment of a data session is received from the residential multipath entity (200), the session request indicating that the session request is for the remote access to the server (235). Then, a session identifier is determined for the remote access including the multipath connection. Then, in a response to the received session request the determined session identifier is transmitted back to the residential multipath entity.

摘要： A technique for controlling a download (110) of an electronic service guide (ESG) for media content distribution services to a user device (102) is proposed. First, a user behaviour related to the user device is monitored. Second, a ranking of fragments of the electronic service guide to be downloaded interactively onto the user device is determined, based on the monitoring. The download of one or more of the fragments to the user device is then initiated based on the ranking. This technique is particularly useful when a transmission capacity available for downloading fragments of the ESG is limited.

摘要： A method of managing a unicast-based media session is disclosed. A user terminal (100) having access to channel identifiers of media channels (400, 410) available at a media server compiles a SIP- based channel request comprising a channel identifier of one of the available media channels (400, 410) and a port identifier of at least one media input port of the terminal (100). This message is sent to a network node (200, 300) for initiating delivery of media data of selected media channel to the announced media input port (115). The SIP-based data signaling also allows switching between unicast- based media channels and switching between unicast-bast and multicast/ broadcast-based media channels during the ongoing media session.

摘要： The invention is embodied in 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 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 may further randomly select a delay time within a contact interval for the selected proxy server, at which the client contacts the selected proxy server at the delay time to initiate post-processing.

摘要： To improve transmission of digital broadcast information, there is proposed a method of transmitting digital broadcast information from a main transmitter (12) to at least one repeater (14). There is generated a composite digital broadcast signal carrying first digital broadcast information according to a first digital broadcast specification (DVB-T) and second digital broadcast information according to a second digital broadcast specification (DVB-H). The composite digital broadcast is then broadcasted such that the second digital broadcast information (DVB-H) is sent in a transmission mode used for transmission of the first digital broadcast information (DVB-T).

摘要： The invention is dedicated to a method for scheduling the delivery of a plurality of data portions to respective recipients in a data distribution network, wherein the recipients are commonly utilizing a bottleneck element limiting the performance of the data distribution network. The invented method comprises the steps of: determining (S1) a preferred time span for delivering the plurality of data portions according to a capacity of the bottleneck element and an amount of data to be delivered, delaying (S3) the delivery of a data portion for a delay that is determined (S2) according to the preferred time span for delivering.
