Abstract: A method of communication of control information between data processing systems in a multiservices network via a communications channel. The method performs the steps of receiving a session initiation stimulus at a Session Control System(SCS), authenticating the received initiation stimulus in the SCS by referencing the stimulus source and stimulus content to a requested service and generating a proceed signal to a multiservices provider on receipt of an authentication valid signal from a contract database associated with the SCS and generating a service event. In this way, data can be controlled and organized in an ‘a priori’ and sequenced manner for the purposes of generation of information to charge directly or bill a customer.
