Abstract: The invention concerns a method of providing session mobility to an IP based real-time session in a telecommunications network whereby the telecommunications network uses the session initiation protocol for the setup and control of the session. The session comprises a media stream between a first terminal associated to a first network access point of the telecommunications network and a second terminal associated to a second network access point of the telecommunications network. A re-invite session initiation protocol signalling message related to session mobility of said session is intercepted at a session-related session border controller of the telecommunications network. Said session border controller initiates a corresponding session hand-over of said session. In said session hand-over, the media stream of said session is redirected to a new network access point of the first terminal and/or a new terminal.

Abstract: The invention concerns a method for adapting modalities of a dialog between a client (42 to 44) and a server, an interaction server (2) and a computer program product. A set of dialog modality capabilities and/or dialog modality requirements are provided to an interaction server (2). The interaction server (2) mediates between the dialog modality capabilities and/or dialog modality requirements of the client (44) and the server. Further, it selects the dialog modalities of said dialog based on said mediation.
