Abstract

A method and means by which a called telecommunications device (14), connected on an established PSTN telecommunications link (18) with a wireline data processing means caller telecommunications device (12), can initiate a conference call to be set up from the wireline caller device (12) by sending a command signal to the data processing means caller device (12). In response to the command signal, the data processing means caller device (12) executes a signal set, predetermined to cause the PSTN (18) to set up the desired conference link (20) at the caller end of the established link (18). The method can be applied by a called alarm monitoring facility (14) to obtain emergency assistance for a distressed wireline caller (12) by causing a conference link (20) with a caller local PSAP (16) to be set up automatically from the wireline caller device (12). In so doing, the method promotes the acquisition of needed emergency assistance in the least attainable time while accessing the best source of relevant emergency information.

Claims

1. A method for improving the emergency aid response time to a first location having a wireline first telecommunications device which forms a part of a public switched telecommunications network comprising the steps of sensing a predetermined condition at said first location and in response to said sensed condition initiating a communications link between said first telecommunications device and a second telecommunications device at a remote second location by way of said network, establishing a communications link between said first telecommunications device and an emergency response device at a remote third location by way of said network by causing said first device to dial 9-1-1 and establishing communications between said second telecommunications device and said emergency response device.

2. The invention of claim 1 wherein said step of sensing a predetermined condition employs a sensor that is part of an alarm system.

3. The invention of claim 1 wherein said communications link between said first device and said second device is established before establishing said communications link between said first device and said emergency response device.

4. The invention of claim 3 wherein said communications link between said first device and said emergency response device is initiated from said second telecommunications device.

5. A system for improving the emergency aid response time to a first location comprising:

a wireline first telecommunications device at said first location and forming part of a public switched telecommunications network;

a second telecommunications device located at a second location remote from said first location and also forming a part of said public switched telecommunications network;

a third telecommunications device located at a third location remote from said first and second locations, said third telecommunications device also forming a part of said public switched telecommunications network;

sensor means and means responsive to said sensor means for causing said first device to establish a communications link with said second device in response to a predetermined sensed condition;

means for causing said first device to establish a communications link with said third device, and

means for establishing a conference call between said first, second and third devices, wherein said third telecommunications device is an emergency response device and wherein said means for causing said first device to establish communications with said emergency response device causes said first device to dial 9-1-1.

6. The system of claim 5 wherein said means for causing said first device to establish a communications link with said third device is responsive to a signal received from said second device.

7. The system of claim 5 further including an alarm means, said sensor means forming part of said alarm means.

8. A system for improving the emergency aid response time to a first location comprising:

a wireline first telecommunications device at said first location and forming part of a public switched telecommunications network;

a second telecommunications device located at a second location remote from said first location and also forming a part of said public switched telecommunications network;

a third telecommunications device located at a third location remote from said first and second locations, said third telecommunications device also forming a part of said public switched telecommunications network;

sensor means and means responsive to said sensor means for causing said first device to establish a communications link with said second device in response to a predetermined sensed condition;

means responsive to a signal received from said second device for causing said first device to establish a communications link with said third device, and

means for establishing a conference call between said first, second and third devices.

9. The system of claim 8 wherein said third telecommunications device is an emergency response device.

10. The system of claim 9 wherein said means for causing said first device to establish communications with said emergency response device causes said first device to dial 9-1-1 .

11. The system of claim 8 further including an alarm means, said sensor means forming part of said alarm means.
