Abstract

An advanced intelligent network (AIN) comprises a services control point providing fully integrated service logic for both narrowband and broadband communications. In the network, a narrowband switch queries the services control point in response to a telephone call and the services control point interacts with a subscriber via the subscriber's broadband set-top terminal device through an exchange of one or more signaling messages prior to instructing the narrowband switch as to how to complete the call. For example, the signalling messages may include a query from the services control point for data indicating whether the subscriber's broadband set-top terminal device is in use or is turned off. The signaling messages from the services control point may carry information for display. If provided, response messages may carry user input information.
