Abstract: Disclosed are different terminals involved in a conference and arranged in a tree topology. Each terminal stores a list of participating terminals, the types of media streams of each terminal, and a media diagram referring to the processing actions of the terminals, in order to allow the conference to be conducted without a server and in a self-organized manner, providing fault tolerance such that the conference as a whole can overcome the failure of any of the participating terminals, allowing the conference to be reconfigured when a user leaves the same, either because it ceases to respond owing to a problem in the terminal or because the user so desires.

Abstract: This invention refers to a method for providing presence information in telecommunication systems. It comprises the steps of: classifying the plurality of presence information statuses, generated by a plurality of telecommunication services associated to a user A, in groups depending on the telecommunication service; publishing simultaneously the plurality of presence information statuses of user A on a presence server; and notifying a set of presence information statuses from the plurality of the presence information statuses of user A, to a client of the presence server which is a watcher of user A. Finally the set of presence information statuses, notified by the presence server to the watcher, may be displayed on means adapted for displaying content according to their corresponding relevance, priority and expiration time.

Abstract: This invention refers to a method for managing a converged address book capability of a user with an address book and subscribed to converged address book service characterised by defining a service tuple in a presence document stored in a presence server; setting a value of converged address book capability in the service tuple indicating whether converged address book service is supported by the user; publishing the converged address book capability of the user and a user identifier on a converged address book server; receiving updates from the presence server of converged address capabilities of the contacts of the users; and updating a network address book, stored in a converged address book XML document management server, with converged address capabilities of served users.

Abstract: A method for managing presence information. It comprises setting, by a user, a hyper-availability status to active, at any time said user wants to be contacted by his peers in a presence service, and selecting, by said user, at least one service and/or communication means he wants his peers to contact him through, when in said hyper-availability status by associating the at least one service and/or communication means selection to said hyper-availability status.

Abstract: The method and system for synchronizing social networks and Personal Contact Cards (PCC) update the profile of a user published in an Open Mobile Alliance Converged Address Book (OMA CAB) system with the information published and updated on one or more social networks to which the user subscribes, by means of synchronization by polling or synchronization by subscription/notification. To do so, the user sends prior authorization to access the user profile published in the social network to a telecommunication services provider operating the OMA CAB system.
