Abstract

A call to an emergency call center from a device is initiated utilizing a relay service. The device may send a non-voice message to the relay service. The relay service, upon receipt and analysis of the message, may initiate a call to the device. The device, upon receiving the call and determining that the call is from the relay service, may place the call on hold and initiate a call to an emergency call center. Subsequently, the device may establish a multi-party call between the device, the relay service, and the emergency call center. Further, the relay service may maintain multiple communications modes in order to conduct non-voice messages with the device and conduct voice communications with the emergency call center.

Claims (36)

1. A method comprising:

establishing, non-voice communications between the user and a relay service by providing a message to a first device, the first device associated with the relay service;

receiving, by a communications device of the user, a first call including an indicator indicating a determination that an emergency condition exists;

placing, from the communications device, the first call on hold;

initiating, from the communications device, a second call to a second device, the second device associated with an emergency call center; and

establishing a multi-party call comprising voice communications between the user, the first device, and the emergency call center,

wherein the non-voice communications between only the communications device and the first device are maintained concurrently with the voice communications.

2. The method of claim 1 , wherein the determination that an emergency condition exists is determined by the relay service.

3. The method of claim 1 , further comprising communicating with the emergency call center via the relay service.

4. The method of claim 1 , wherein the message is a non-voice message.

5. The method of claim 1 , wherein the voice communications comprise a one-way voice communication from the user to the emergency call center.

6. The method of claim 1 , wherein the voice communications comprise a two-way voice communication between the user and the emergency call center.

7. A device comprising:

a processor; and

memory coupled to the processor, the memory comprising executable instructions that cause the processor to effectuate operations comprising:

establishing non-voice communications between a user of the device and a relay service by providing a message from the user to a first device, the first device associated with the relay service;

receiving a first call an indicator indicating a determination that an emergency condition exists;

placing the first call on hold;

initiating a second call to a second device, the second device associated with an emergency call center; and

establishing a multi-party call comprising voice communications between the user, the first device, and the emergency call center,

wherein the non-voice communications with only the first device is maintained concurrently with the voice communications.

8. The device of claim 7 , wherein the determination that an emergency condition exists is determined by the relay service.

9. The device of claim 7 , the operations further comprising communicating with the emergency call center via the relay service.

10. The device of claim 7 , wherein the message is a non-voice message.

11. The device of claim 7 , wherein the voice communications comprise a one-way voice communication from the user to the emergency call center.

12. The device of claim 7 , wherein the voice communications a two-way voice communication between the user and the emergency call center.

13. The device of claim 7 , wherein the device comprises a mobile communications device.

14. A computer-readable storage medium comprising executable instructions that cause a processor of a communications device executing the executable instructions to effectuate operations comprising:

establishing non-voice communications between a user using a communications device and a relay service by providing a message from the communications device to a first device, the first device associated with the relay service;

receiving a first call at the communications device, the first call including an indicator indicating a determination that an emergency condition exists;

placing the first call on hold;

initiating a second call to a second device, the second device associated with an emergency call center; and

establishing a multi-party call comprising voice communications between the user, the first device, and the emergency call center,

wherein the non-voice communications between only the communications device and the first device are maintained concurrently with the voice communications.

15. The computer-readable storage medium of claim 14 , the operations further comprising communicating with the emergency call center via the relay service.

16. The computer-readable storage medium of claim 14 , wherein the voice communications comprise a one-way voice communication from the user to the emergency call center.
