Abstract

L'invention concerne un procédé et un système pour le traitement d'un service d'itinérance dans le domaine des techniques de communication. Le procédé consiste à déterminer un dispositif de commutation douce (softX) local d'un terminal d'utilisateur itinérant et à activer le service du terminal d'utilisateur itinérant pour ce softX local, ledit softX local traitant alors le service du terminal d'utilisateur itinérant selon les données utilisateur et les moyens de traitement de service du terminal d'utilisateur itinérant. Le présent mode de réalisation de l'invention permet d'activer un service de communication du terminal d'utilisateur pour le softX local correspondant en vue d'un traitement, le terminal d'utilisateur pouvant alors utiliser tous les services ouverts par le softX local. Ainsi, les moyens et le service de l'utilisateur ne peuvent pas être perdus et un contrôle centralisé d'authentification d'itinérance peut être assuré.
