Abstract

A system and method for emergency telephone call notification. The system includes an AIN capable switch, a service control point (SCP) having a database of designated contact numbers associated with a service subscriber telephone number, and an intelligent peripheral (IP) in communication with the SCP for contacting the designated contact numbers. The method includes the steps of recognizing an N11 trigger and the SCP initiating telephone calls, via the IP, to each of the contact numbers corresponding to the telephone number of the subscriber making the emergency telephone call.

Claims

1. A method of notifying a designated telephone number that an emergency telephone call has been made from a subscriber telephone, the method comprising:

receiving an emergency telephone call from a subscriber telephone in communication with a switch;

recognizing the emergency telephone call at the switch;

connecting the subscriber telephone to a public safety access point associated with the emergency telephone call;

generating, in response to the emergency telephone call connected, a first call to a designated telephone number, the first call being different from the emergency telephone call; and

providing a message, via the first call, that the subscriber telephone has been utilized to place the emergency telephone call.

2. The method of claim 1, wherein the emergency telephone call is a 911 call.

3. The method of claim 2, wherein recognizing the emergency telephone call comprises recognizing an N11 trigger.

4. The method of claim 1 further comprising:

accessing a database storing a plurality of subscriber telephone numbers and a plurality of designated telephone numbers associated with each respective subscriber telephone number in the plurality of subscriber telephone numbers; and

automatically playing an announcement that an emergency telephone call has been placed from the subscriber telephone number.

5. The method of claim 1, further comprising supplying a caller identification message to the designated telephone number indicating an incoming call from an emergency call notification service.

6. The method of claim 1, wherein recognizing the emergency telephone call further comprises utilizing a caller identification generator having a predesignated message stored in a memory.

7. The method of claim 4, further comprising dialing the designated telephone number and waiting a predetermined number of rings before trying to contact a second designated telephone number selected from the plurality of designated telephone numbers associated with a subscriber telephone number corresponding to the subscriber telephone.

8. The method of claim 1, further comprising:

automatically generating a second call to connect the designated telephone number to the subscriber telephone if a person answers the first call.

9. A non-transitory computer readable medium storing computer program instructions, which, when executed on a controller, cause the controller to perform operations comprising:

receiving an emergency telephone call from a subscriber telephone in communication with a switch;

recognizing the emergency telephone call at the switch;

connecting the subscriber telephone to a public safety access point associated with the emergency telephone call;

generating, in response to the emergency telephone call connected, a first call to a designated telephone number, the first call being different from the emergency telephone call; and

providing a message, via the first call, that the subscriber telephone has been utilized to place the emergency telephone call.

12. The non-transitory computer readable medium of claim 9 further comprising computer program instructions, which, when executed on a controller, cause the controller to perform operations comprising:

accessing a database storing a plurality of subscriber telephone numbers and a plurality of designated telephone numbers associated with each respective subscriber telephone number in the plurality of subscriber telephone numbers; and

automatically playing an announcement that an emergency telephone call has been placed from the subscriber telephone number.

13. The non-transitory computer readable medium of claim 9, further comprising computer program instructions, which, when executed on a controller, cause the controller to perform operations comprising:

supplying a caller identification message to the designated telephone number indicating an incoming call from an emergency call notification service.

14. The non-transitory computer readable medium of claim 9, further comprising computer program instructions, which, when executed on a controller, cause the controller to perform operations comprising:

utilizing a caller identification generator having a predesignated message stored in a memory.

15. The non-transitory computer readable medium of claim 12, further comprising computer program instructions, which, when executed on a controller, cause the controller to perform operations comprising:

dialing the designated telephone number and waiting a predetermined number of rings before trying to contact a second designated telephone number selected from the plurality of designated telephone numbers associated with a subscriber telephone number corresponding to the subscriber telephone.

16. The non-transitory computer readable medium of claim 9, further comprising computer program instructions, which, when executed on a controller, cause the controller to perform operations comprising:

automatically generating a second call to connect the designated telephone number to the subscriber telephone if a person answers the first call.

10. The non-transitory computer readable medium of claim , wherein the emergency telephone call is a 911 call.

11. The non-transitory computer readable medium of claim 10, further comprising computer program instructions, which, when executed on a controller, cause the controller to perform operations comprising:
