Abstract
(EN) A method of establishing a combinational multimedia session between at least two end user terminals, the method comprising: discovering at each end user terminal the end user authorization to use the multimedia service; subsequently establishing a circuit switched connection between the end user terminals via one or more telecommunication networks; upon successful discovery of end user authorization to use the multimedia service and prior to or following the establishment of said circuit switched connection, discovering at each end user terminal the multimedia capabilities of the or each other terminal; and whilst the circuit switched connection is established, establishing an IP multimedia subsystem session between the end user terminals via one or more IP multimedia subsystem networks, and transferring IP multimedia information between the user terminals, said multimedia information relating to a service supported by both or all user terminals.
(FR) L'invention concerne un procédé d'établissement d'une session multimédia combinée entre au moins deux terminaux d'utilisateur, consistant à détecter l'autorisation d'utilisateur terminal sur chaque terminal pour l'utilisation du service multimédia; à établir ensuite une connexion à commutation par circuit entre les terminaux par l'intermédiaire d'un ou plusieurs réseaux de télécommunication; à déterminer, en cas de détection de l'autorisation d'utilisation du service multimédia, les capacités multimédia de chaque terminal sur chaque terminal; à établir, tandis que la connexion à commutation par circuit est établie, une session de sous-systèmes multimédia IP entre les terminaux par l'intermédiaire d'un ou plusieurs réseaux de sous-systèmes multimédia IP; et, à transférer des informations multimédia IP entre les terminaux, lesdites informations concernant un service supporté par les deux ou tous les terminaux.
