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: Information on the identity of each user connecting via a wireless device is obtained using a prior process of authentication and context information and/or the status of the user; a characteristics vector is generated for each user, which comprises the context information and/or the user status and a user profile. Permissions are assigned to each user, determining the type of secured network resources each user is permitted to access, depending on their characteristics vector; and a secured-network-resource access check is performed, enabling the transfer of data only to/from resources permitted for each user, as a function of the permissions assigned.

Abstract: The present invention relate to a method and a system applicable to telecommunications systems, providing an additional guaranteeing factor of the identity provided by a user when he/she accesses a service provider based on the coincidence of the location of the user when the latter is carrying a device susceptible to being located 10 by means of GSM, GPRS, UMTS, WIFI and GPS technologies, with at least one zone of reliable access associated with said user.
