Abstract

Abstract A communications system is arranged to route a database-queried call (900-number or 800-number call) to a subscriber (pay-per-call sponsor or 800-number customer), and to deliver to the subscriber information identifying the call as a database-queried call, as opposed to a switched-line or POTS call.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 90 words
A method of completing a telephone call, the method comprising the steps of: receiving in a communications network a telephone number dialed by a caller to request a database-queried communications service, said telephone number being the only telephone number translatable to at least one POTS number; translating the received telephone number to said at least one POTS number; completing the call to a subscriber's telephone set associated with the said at least one POTS number; and delivering to a monitor associated with said telephone set information indicative of said translation.
Claim 2
Independent Claim 90 words
A method of completing a telephone call, the method comprising the steps of: receiving in a communications network a telephone number dialed by a caller to request a database-queried communications service, said telephone number being the only telephone number translatable to at least one POTS number; translating the received telephone number to said at least one POTS number; completing the call to a subscriber's telephone set associated with the said at least one POTS number; and delivering to a monitor associated with said telephone set information indicative of said translation.
Claim 3
Dependent Claim 19 words
The method of claim 1 wherein said telephone number dialed by the caller is a pay-per-call service telephone number.
Claim 4
Dependent Claim 19 words
The method of claim 1 wherein said telephone number dialed by the caller is a freephone service telephone number.
Claim 5
Dependent Claim 35 words
The method of claim 1 wherein said delivering step includes the step of: routing said information indicative of said translation via a channel that is different from the channel over which the call is routed.
Claim 6
Dependent Claim 32 words
