Abstract: A system and method of managing the amount of usage of IP access to services for a user group are provided. The system includes: a user terminal through which a user interacts with the system; a user database for storing a user data; a real-time billing mediator for monitoring and collecting data traffic flowing through the system; a charging server for reading the user data from the user database and sending the user data to the real-time billing mediator; a user group provisioning station for updating the user data; and an application/content server for storing applications/content. The user group, rather than a network operator, provides controlling and provisioning of the IP access of individual users of the user group in the system.
