Abstract

A system and method are disclosed for providing an automatic call-back when a calling party encounters a ring-no-answer condition upon calling a called party. An exemplary system includes: a first originating switch node (OSN) coupled to a first originating telephone call location corresponding to a calling party and, a terminating switch node (TSN) coupled to a destination telephone call location corresponding to a called party; a database coupled to the TSN for storing the called party'"'"'s times of calling activity; a processor coupled to the TSN and to the database for processing the times of calling activity to determine a best time to call (BTTC) the called party (wherein the BTTC comprises a best exact time and/or a window of time) and providing the TSN with the BTTC; a signaling network for routing the BTTC to the OSN; and an adjunct coupled to the OSN for receiving the calling party'"'"'s automatic call-back request and initiating an automatic call back to the calling party at the BTTC the called party. Upon receiving the automatic call-back request, the adjunct provides the calling party with the BTTC. The adjunct also requests the calling party to enter a time at which the calling party is most likely to be available to receive an automatic call-back and, if the time entered in response to said request is the best exact time or, within the window of time, the adjunct initiates an automatic call-back to said calling party at the time entered.

Claims

1. A system for providing an automatic call-back to a caller at a calling party number that encounters a ring-no-answer condition upon calling a called party number, comprising:

a switching network having switches for routing telephone calls;

said switching network comprising a first originating switch node coupled to a first originating telephone call location corresponding to said calling party number and, a terminating switch node coupled to a destination telephone call location corresponding to said called party number;

a database coupled to said terminating switch node for storing information regarding times of calling activity of said called party number;

a processor coupled to said terminating switch node and to said database for analyzing said information to determine a best time to call said called party number and providing said terminating switch node with data indicating said best time to call said called party number;

a signaling network coupling switches in said switching network to one another for transmitting said data indicating said best time to call said called party number to said originating switch node; and

an adjunct coupled to said originating switch node for receiving an automatic call-back request from said caller at said calling party number and initiating said automatic call-back to said calling party number at said best time to call said called party number.

2. The system of claim 1 wherein said best time to call said called party number comprises a best exact time and a window of time.

3. The system of claim 2 wherein said best exact time corresponds to a highest probability of availability of said called party number for any instant in time and said window of time corresponds to a predetermined least acceptable probability of availability of said called party number.

4. The system of claim 2 wherein said adjunct conveys said best exact time to said caller.

5. The system of claim 4 wherein said adjunct requests said caller to enter a time at which said calling party number is most likely available to receive an automatic call-back and, if said time entered in response to said adjunct request is said best exact time, said adjunct initiates said automatic call-back to said calling party number at said best exact time.

6. The system of claim 4 wherein said adjunct requests said caller to enter a time at which said calling party number is most likely available to receive an automatic call-back and, if said time entered in response to said adjunct request is within said window of time, said adjunct initiates said automatic call-back to said calling party number at said time entered.

7. The system of claim 2 wherein said adjunct conveys said window of time to said caller.

8. The system of claim 7 wherein said adjunct requests said caller to enter a time at which said calling party number is most likely available to receive an automatic call-back and, if said time entered in response to said adjunct request is said best exact time, said adjunct initiates said automatic call-back to said calling party number at said best exact time.

9. The system of claim 7 wherein said adjunct requests said caller to enter a time at which said calling party number is most likely available to receive an automatic call-back and, if said time entered in response to said adjunct request is within said window of time, said adjunct initiates said automatic call-back to said calling party number at said time entered.

10. The system of claim 1, whereupon completing said automatic call-back to said calling party number, said adjunct transmits a pre-recorded announcement to said caller via said switching network indicating that an attempt will be made to complete a telephone call to said called party number in satisfaction of said automatic call-back request from said caller at said calling party number.

11. The system of claim 10, whereupon completing said telephone call to said called party number, said adjunct merges said telephone call to said calling party number with said telephone call to said called party number.

12. A method for providing an automatic call-back to a caller at a calling party number that encounters a ring-no-answer condition upon calling a called party number, comprising the steps of:

storing times of calling activity of said called party number over a period of time prior to said calling party number encountering said ring-no-answer condition;

determining a best time to call said called party number based upon said stored times of calling activity; and

initiating said automatic call-back to said calling party number at said best time to call said called party number.

13. The method of claim 12 wherein said best time to call said called party number comprises a best exact time and a window of time and, further comprising the step of:

providing said caller with said best exact time, prior to said step of initiating said automatic call-back.

14. The method of claim 13 further comprising the steps of:

requesting said caller to enter a time at which said calling party number is most likely available to receive an automatic callback;

comparing said time entered in response to said request with said best exact time; and

initiating said automatic call-back to said calling party number at said best exact time if said entered is said best exact time.

15. The method of claim 13 further comprising the steps of:

requesting said caller to enter a time at which said calling party number is most likely available to receive an automatic call-back;

comparing said time entered in response to said request with said window of time; and

initiating said automatic call-back to said calling party number at said time entered if said time entered is within said window of time.

16. The method of claim 12 wherein said best time to call said called party number comprises a best exact time and a window of time and, further comprising the step of:

providing said caller with said window of time, prior to said step of initiating said automatic call-back.

17. The method of claim 16 further comprising the steps of:

requesting said caller to enter a time at which said calling party number is most likely available to receive an automatic call-back;

comparing said time entered in response to said request with said best exact time; and

initiating said automatic call-back to said calling party number at said best exact time if said time entered is said best exact time.

18. The method of claim 16 further comprising the steps of:

requesting said caller to enter a time at which said calling party number is most likely available to receive an automatic call-back;

comparing said time entered in response to said request with said window of time; and

initiating said automatic call-back to said calling party number at said time entered if said time entered is within said window of time.

19. The method of claim 12, wherein said best time to call comprises a best exact time.
