Abstract

A method and apparatus for detecting a stale number. A stale number detection device obtains a call number, a call number contact creation date, and a call number issue date for the call number. The stale number detection device determines that a stale number state exists when the call number issue date is later than the call number contact creation date. The stale number detection device generates a stale number notification based on the stale number state.

First claim

We claim:

1. A method for detecting a stale number, the method comprising:
receiving, via a wireless network interface, a call request from a portable communication device, the call request including a call number and a call number contact creation date for the call number;
obtaining, by a processor in communication with the wireless network interface, a call number issue date for the call number;
determining, by the processor, that a stale number state exists when the call number issue date is later than the call number contact creation date; and
generating, by the processor, a stale number notification based on the stale number state.

2. The method of claim 1 , further comprising denying, by the processor, the call request when the stale number state exists.

3. The method of claim 1 , further comprising:
determining, by the processor, a subscriber identifier based on the call number when the stale number state exists; and
determining, by the processor, an active number based on the subscriber identifier;
wherein the stale number notification includes the active number.

4. The method of claim 1 , further comprising:
sending, by the processor via the wireless network interface, the stale number notification to the portable communication device; and
denying, by the processor, the call request.

5. The method of claim 1 , further comprising:
prompting, by the processor, for permission from a recipient device to complete the call request when the stale number state exists; and
completing the call request, by the processor, when permission to complete the call request is received from the recipient device.

6. The method of claim 5 , wherein completing the call request includes one of a group consisting of accepting a voice telephone call and accepting a text message.

7. The method of claim 1 , further comprising:
sending, by the processor via the wireless network interface, the stale number notification to the portable communication device; and
completing the call request when permission to complete the call request is received from the portable communication device.

8. The method of claim 7 , wherein completing the call request includes one of a group consisting of placing a voice telephone call and sending a text message.

9. A stale number detection device, the stale number detection device comprising:
a wireless network interface;
a memory having
an obtained call number issue date for the call number; and

a processor, coupled to the wireless network interface and the memory and configured to
receive, via the wireless network interface, a call request generated by a portable communication device, the call request including a call number and a call number contact creation date for the call number,
access the memory,
determine that a stale number state exists when the obtained call number issue date is later than the call number contact creation date, and
generate a stale number notification based on the stale number state.

10. The stale number detection device of claim 9 , wherein the processor is further configured to deny the call request when the stale number state exists.

11. The stale number detection device of claim 9 , further comprising an input/output interface coupled to a database, wherein the processor is further configured to
retrieve from the database a subscriber identifier based on the obtained call number when the stale number state exists;
retrieve from the database an active number based on the subscriber identifier; and
wherein the stale number notification includes the active number.

12. The stale number detection device of claim 9 , wherein the processor is further configured to
send the stale number notification to the portable communication device via the wireless network interface; and
deny the call request.

13. The stale number detection device of claim 9 , wherein the input/output interface is further coupled to a recipient device and the processor is further configured to
prompt for permission from the recipient device to complete the call request when the stale number state exists; and
complete the call request when permission to complete the call request is received from the recipient device.

14. The stale number detection device of claim 9 , wherein completing the call request includes one of a group consisting of accepting a voice telephone call and accepting a text message.

15. The stale number detection device of claim 9 , wherein the processor is further configured to
send the stale number notification to the portable communication device via the wireless network interface;
complete the call request when permission to complete the call request is received from the portable communication device.

16. The stale number detection device of claim 15 , wherein completing the call request includes one of a group consisting of placing a voice telephone call and sending a text message.

17. The stale number detection device of claim 9 , further comprising an input/output interface coupled to a database, wherein the processor is configured to retrieve from the database at least one from the group consisting of the call number, the call number contact creation date, and the obtained call number issue date.

18. The stale number detection device of claim 9 , wherein the stale number detection device is incorporated into at least one from the group consisting of the portable communication device, a recipient device identified by the call number, and a communications network control system coupled to the portable communication device and the recipient device.

19. The method of claim 1 , wherein receiving a call request from a portable communication device includes receiving a call request from one selected from the group consisting of a smart telephone, a portable radio, and a tablet computer.

20. The stale number detection device of claim 9 , wherein the portable communication device is one selected from the group consisting of a smart telephone, a portable radio, and a tablet computer.
