Abstract

A method of providing an emergency alert service using a telephone network comprises transmitting, to a subscriber of the emergency alert service, an emergency message within a name parameter of a caller-identification message. As an alternative to or in addition to the aforementioned act, the method may comprise transmitting, to a subscriber, an emergency message within a name parameter of a caller-identification-with-call-waiting message. As an alternative to or in addition to the aforementioned acts, the method may comprise transmitting, to a subscriber, an emergency message within a talking-call-waiting message.

Claims

1. A method of providing an emergency alert service using a telephone network, the method comprising:

receiving a message indicating an issuance of an emergency;

based on the message, determining a subset of a plurality of subscribers of the emergency alert service that is affected by the emergency, the subset comprising a first subscriber, a second subscriber and a third subscriber;

transmitting, to the first subscriber, a first emergency message within a name parameter of a caller-identification message;

transmitting, to the second subscriber, a second emergency message within a name parameter of a caller-identification-on-call-waiting message while the second subscriber has an in-progress call; and

transmitting, to the third subscriber, a third emergency message within a talking-call-waiting message while the third subscriber has an in-progress call.

2. The method of claim 1 wherein the caller-identification message and the caller-identification on-call-waiting message are multiple data message format (MDMF) messages.

3. A method of providing an emergency alert service using a telephone network, the method comprising:

transmitting, to a subscriber of the emergency alert service, an emergency message within a name parameter of a caller-identification message.

4. The method of claim 3 further comprising:

transmitting, to the subscriber, an all-clear message within a name parameter of a caller-identification message.

5. The method of claim 3 further comprising:

transmitting, to the subscriber, an all-clear message within a name parameter of a caller-identification-with-call-waiting message.

6. The method of claim 3 further comprising:

transmitting, to the subscriber, an all-clear message within a talking-call-waiting message.

7. The method of claim 3 wherein the caller-identification message is a multiple data message format (MDMF) message.

8. The method of claim 3 wherein the caller-identification message is a caller-identification-on-call-waiting message, and wherein said transmitting the emergency message is performed while the subscriber has an in-progress call.

9. A method of providing an emergency alert service using a telephone network, the method comprising:

transmitting, to a subscriber of the emergency alert service, an emergency message within a talking call waiting message while the subscriber has an in-progress call.

10. The method of claim 9 further comprising:

transmitting, to the subscriber, an all-clear message within a name parameter of a caller-identification message.

11. The method of claim 9 further comprising:

transmitting, to the subscriber, an all-clear message within a name parameter of a caller-identification-with-call-waiting message.

12. The method of claim 9 further comprising:

transmitting, to the subscriber, an all-clear message within a talking-call-waiting message.

13. A system for providing an emergency alert service using a telephone network, the system comprising:

a telephone network element to transmit, to a subscriber of the emergency alert service, an emergency message within a name parameter of a caller-identification message.

14. The system of claim 13 wherein the telephone network element further is to transmit, to the subscriber, an all-clear message within a name parameter of a caller-identification message.

15. The system of claim 13 wherein the telephone network element further is to transmit, to the subscriber, an all-clear message within a name parameter of a caller-identification-with-call-waiting message.

16. The system of claim 13 wherein the telephone network element further is to transmit, to the subscriber, an all-clear message within a talking-call-waiting message.

17. The system of claim 13 wherein the caller-identification message is a multiple data message format (MDMF) message.

18. The system of claim 13 wherein the caller-identification message is a caller-identification-on-call-waiting message, and wherein the telephone network element is to transmit the emergency message while the subscriber has an in-progress call.

19. The system of claim 13 wherein the telephone network element comprises an intelligent peripheral.

20. The system of claim 13 wherein the telephone network element comprises a compact service node.

21. A system for providing an emergency alert service using a telephone network, the system comprising:

a telephone network element to transmit, to a subscriber of the emergency alert service, an emergency message within a talking call waiting message while the subscriber has an in-progress call.

22. The system of claim 21 wherein the telephone network element further is to transmit, to the subscriber, an all-clear message within a name parameter of a caller-identification message.

23. The system of claim 21 wherein the telephone network element further is to transmit, to the subscriber, an all-clear message within a name parameter of a caller-identification-with-call-waiting message.

24. The system of claim 21 wherein the telephone network element further is to transmit, to the subscriber, an all-clear message within a talking-call-waiting message.

25. The system of claim 21 wherein the telephone network element comprises an intelligent peripheral.

26. The system of claim 21 wherein the telephone network element comprises a compact service node.
