Abstract: SIP is a popular protocol used in communications over IP, which however is incompatible with many other protocols used for the set-up of calls in other networks. SIP-based transactions are converted through the use of a grammar by a proxy user agent (110) into a format which is usable by non-SIP capable end user devices, e.g., a mobile phone, such that the end user devices (116) has access on services and applications which use SIP-based transactions.

Abstract: 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.

Abstract: The present invention relates to a method and a node in an IETV network. The node according to the present invention is configured to use the knowledge of the user channel switching behavior in order to predict user channel switching and to make the channels predicted to be used available close to the STB of the user in advance of the anticipated channel switch.

Abstract: Methods and systems are provided to increase the security of a user's information as well as perform secure transactions. More particularly, in one exemplary embodiment, a user inputs information into a database which enables or disables information which may be requested by a third party establishment. In another exemplary embodiment, location based transaction authentication is used.

Abstract: A method and emulating communication node for providing service access in a second network to a roaming user equipment (UE) registered in a first network. The emulating communication node comprises and application server (AS) and a global service interface (GSI). The AS comprises a processing module for operating the AS, interfacing with a global service interface (GSI), receiving from a user equipment (UE) a request including access information of the UE for receiving services when located in a second packet data network, determining the service preferences for the requested service delivery to the UE and applying the determined service preferences to the requested service in the second packet data network. The GSI comprises a processing module for retrieving from an account database a user profile associated to the UE and interfacing the AS and service providers in the first and second networks.

Abstract: Methods, data servers, signal and destination device for optimizing asynchronous delivery of a data content. Once it is determined that more than one instances of the data content are asynchronous, attempts are made to merge them into a fewer number of synchronized instances. It is done by providing a synchronization instance before delivering the synchronized instance and the synchronization instance of the data content. The synchronization instance may be consumed first while the synchronized instance is stored in cache. Thereafter, the synchronized instance is consumed from the cache upon completion of the synchronization instance. Alternatively, the synchronization instance may have an accelerated bit rate and be consumed while it is being received and stored in cache. The synchronized instance is thereafter consumed upon completion of the synchronization instance.
