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: 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.
