International ClassH04Q 007/08AbstractA mobile telephone, or personal communication services subscriber who wishes directory assistance services is connected in the conventional manner to an operator who identifies a destination telephone number desired by the subscriber. As known in the prior art, the operator then initiates a call connecting the subscriber to the destination telephone number. In a preferred embodiment, the operator locates a desired destination telephone number in a computer database, and can select automatic dialing of the located number. Further, rather than dropping all further involvement with the call, the preferred embodiment of the present invention continually monitors the connection thereby established for a predetermined DTMF signal issued by the customer, such as that obtained by pressing the "*" button. If such a signal is detected, the customer is transferred to a directory assistance operator, who can then provide whatever further assistance is needed (e.g., providing further directory assistance). If a busy signal or non-answering party is detected, a customer is given a plurality of options including leaving a recorded message or page, or a predetermined alphanumeric message or page for the called party. In this case, the system automatically tries, repeatedly, to deliver the recorded message or page and, optionally, confirms successful or failed message delivery to the calling party.Other References
