Abstract
A high-speed information service system is provided which uses a unique identifier received during call setup to retrieve automatically a personalized profile for an information service subscriber. The identifier uniquely identifies the subscriber, thereby allowing the information retrieval process to begin immediately after the call is setup. The system utilizes Integrated Services Digital Networks (ISDN) signaling and temporary, 'out-of-band' signaling to improve information retrieval capability. ISDN signaling permits electronic addressing of information requested by the subscriber, thereby eliminating the delays which accompany DTMF signal processing. Communications between an information service provider and an individual information source are conducted using out-of-band signaling. That is, call setup and information request are processed using a channel other than the channel which carries data between the information service provider, the information source and the subscriber.
