Abstract: A method of providing a content delivery service to an actual user of a communication system supporting push-to-talk. The content delivery service includes delivering a content to the actual user, wherein the method includes associating a virtual user to said content; establishing a push-to-talk session involving the actual user and the virtual user; and delivering the content from the virtual user to the actual user through the established push-to-talk session.

Abstract: A method of providing a push-to-x service to a user of a data terminal which is connected to a packet-switched network includes, at a gateway interfacing the packet-switched network and the framework supporting the push-to-x service: receiving from the data terminal a request for accessing the push-to-x service; checking a user class to which the user belongs; and, according to the user class, assigning a push-to-x identity to the user either by selecting the push-to-x identity from a set of predefined push-to-x identities, or by retrieving the push-to-x identity from a user profile table; and accessing the framework and the push-to-x service by using the push-to-x identity.

Abstract: A communication system suitable for supporting services based on PoC, includes a PoC server, a first terminal provided with a first PoC client module and a second terminal provided with a second PoC client module. The first PoC client module includes a generic user interface application suitable for generating a generic user interface configured to provide a user of the first terminal with a call service based on PoC and a specialized user interface application suitable for generating a specialized user interface configured to provide the user with a content exchange service based on PoC.

Abstract: A method serves for customizing the operation of a telephonic terminal, in particular a mobile telephonic terminal of a user. A profile file is provided for storing information relating to operation parameters of the telephonic terminal. The information stored in the profile file can be modifiable by the user. Additionally, a policy file is provided for storing information relating to the possibility to modify one or more of the operation parameters by the user. Typically, a profile manager software module manages the profile file and a policy manager software module manages the policy file. When a user attempts to carry out modifications on information stored in the profile file, the profile managing module interacts with the policy managing module in order to check the possibility to carry out the modifications and to get the authorisation or the denial from the policy managing module.
