摘要:
A flexible and context-aware delivery scheme for uniform resource locators builds on a generic representation that can be used for whichever binary content is to be delivered to a client. It can also be applied to improve the network operations of a network operator, the user's perceived quality of experience, and the costs of a content provider that does not need to encode and support different codecs and transport mechanisms.

Disclosed is a DRM device and method for providing secure linking to a user identity. A first request is sent to a subscriber identity module. A message is received from the subscriber identity module via a secure authenticated channel. The message comprises at least a master key identifier, a random number, and a derived key. In response to the message, a second request is sent to a DRM server. The second request comprises at least a master key identifier, the device identifier, and a random number. Also disclosed is a DRM server and method for providing secure linking to a user identity. A first request is received from a DRM device. The first request comprises at least master key identifier, a device identifier, and a random number. The DRM device is authenticated. A second request for an application specific key is sent to a trusted key management server. The second request comprises at least a master key identifier. At least a key is received from the trusted key management server. A derived key is determined from the key received from the trusted key management server based at least on the device identifier and the random number. A challenge/response scheme is used to determine whether the derived key of the DRM server matches a derived key of the DRM device.
摘要:
A method and an apparatus in a multimedia network node (312), for providing a relevant service level for a first subscriber (A) in a multimedia session with a second subscriber (B). A service level policy has been defined for each subscriber. A session negotiation message (3:1) sent by the first subscriber is first obtained. A required service level of the first subscriber is then detected from a service level parameter that the first subscriber has added to the negotiation message. The policy is updated (3:2a) for the second subscriber if the required service level cannot be allowed in the first subscriber's receive direction according to the original policy of the second subscriber, to allow that network resources are reserved (3:3) for the session such that the first subscriber will receive media (3:4) with the required service level.

There is described a technique, executed in a node (600, 602, 604, 606, 620, 622, 632, 634) for transmitting, processing and/or producing media content, of providing a media structure (102, 204) for customising a main media content (100, 208). Said technique may comprise the steps of: a. analysing said main media content (100, 208) regarding events of interest in said main media content (100, 208), and thereby identifying at least one event of interest, b. based on the analysis performed in step a., storing descriptive information (108, 210), relating to said main media content (100, 208), in said media structure (102, 204). The technique comprises a method and an arrangement.
摘要:
Method and apparatus in a router (200) of an IP network, for providing a relevant and expected service level for a first subscriber (A) in a peer-to-peer session with a second subscriber (B). When a session setup message (PATH) sent from the first subscriber is received (2:2) at the router, a required service level is detected from a service level indicator in the received message, and a service level definition of an operator of the first subscriber is obtained (2:3) for interpreting the service level indicator. Communication resources required for data transmission during the session are determined (2:4) according to the detected service level as interpreted by the service level definition. The determined communication resources are then booked (2:4) in the router, and the session setup message is forwarded (2:7) to a next hop node in the transmission path towards the second subscriber.

One or more push mail filters of an email dispatcher is automatically, and preferably in an event-driven and dynamic manner, adapted to decrease the number of messages transmitted to a battery-operated user equipment (UE) based on one or more battery conservation parameters monitored by or for the UE.

Mobile communication network (301), mobility node (322) and method for selecting, as a user terminal (304) moves in the mobile communication network (301) from a first node (306) to a second node (311), a cache (308 or 312) that stores a desired content and is closest to the user terminal (304). The method includes receiving a request from the user terminal (304) for a segment of the desired content; querying a mobility functionality (300) run by the mobile communication network (301) about an internet protocol, IP, address of a cache that stores the segment of the desired content; based on a location at the first node (306) or the second node (311) of the user terminal that sent the request, determining the cache (308 or 312) that stores the segment of the desired content and has a location closest to the user terminal (304); and providing the user terminal (304) with an answer that includes the IP address of the closest cache that stores the segment of the desired content.

摘要:
A method of managing a unicast-based media session is disclosed. A user terminal having access to channel identifiers of media channels available at a media server compiles a SIP-based channel request comprising a channel identifier of one of the available media channels and a port identifier of at least one media input port of the terminal. This message is sent to a network node for initiating delivery of media data of selected media channel to the announced media input port. 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.
