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.

Personalized information service system

Telephone calls are directed from a first telecommunications platform to a second telecommunications platform, together with an identifier which uniquely identifies the call and enables telecommunication switches to monitor and maintain control over the call. The unique identifier enables the call to be returned from the second platform to the first platform. Once returned to the first platform, the call can be directed to a third telecommunications platform (and, subsequently, back to the first platform), without requiring the caller to place another call or to re-verify the caller's identity. The call identifier is used either to automatically return the call to the first platform after the occurrence of a predetermined event, or upon detecting predetermined, caller-dialed keystrokes indicating that the caller wishes to return to the interexchange carrier platform.

Method for switching telephone calls to information service providers

A high-speed information service system is provided which uses Primary Rate Interface (PRI) 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.
