Abstract

A communication device receives an incoming call message for an incoming call. The incoming call message has data indications indicating whether the incoming call is an emergency call from a public safety answering point entity. If the data indications do not indicate that the incoming call is an emergency call from the public safety answering point, then the communication device performs non-emergency call processing for the incoming call. On the other hand, if the data indications indicate that the incoming call is an emergency call, then the communication device causes the emergency call to be answered automatically.

Claims

1. A method in a communication device, the method comprising:

receiving an incoming call message for an incoming call, the incoming call message having data indications indicating whether the incoming call is an emergency call from a public safety answering point entity;

if said data indications do not indicate that the incoming call is an emergency call from the public safety answering point, then performing non-emergency call processing for the incoming call; and

if said data indications indicate that the incoming call is an emergency call, then causing the emergency call to be answered automatically by the communication device.

2. The method of claim 1, wherein the emergency call is answered automatically without detecting a manual answer signal via a user interface of the communication device.

3. The method of claim 1, further comprising:

if said data indications indicate that the incoming call is an emergency call, then refraining from producing an audible alert at the communication device for alerting of the emergency call.

4. The method of claim 1, further comprising:

causing a mobile identifier which identifies the communication device to be transmitted via a communication network to the public safety answering point entity; and

wherein said receiving the incoming call message comprises receiving an incoming call message addressed to the mobile identifier.

5. The method of claim 1, further comprising:

if the data indications indicate that the incoming call is the emergency call, then refraining from performing a DR (ALERT) process and a U7 CALL RECEIVED process when answering the emergency call.

6. The method of claim 1, wherein a user interface of the communication device comprises a display, a speaker, and a microphone, and wherein the act of causing the emergency call to be answered automatically by the communication device comprises the further acts of enabling the speaker to produce audible signals from the public safety answering point entity and enabling the microphone to receive audible signals at the communication device.

7. The method of claim 1, wherein the communication device has a handset talk mode and a speakerphone talk mode, the method further comprising:

if the data indications indicate that the incoming call is an emergency call, then enabling the speakerphone talk mode of the communication device without detecting a manual speakerphone activation signal via the user interface.

8. The method of claim 1, wherein the communication device comprises a wireless telephony device operative to place an emergency call via a wireless communication network.

9. A computer program product, comprising:

a non-transitory computer readable medium;

computer instructions stored in the non-transitory computer readable medium;

the computer instructions being executable by one or more processors of a communication device for;

receiving an incoming call message for an incoming call, the incoming call message having data indications indicating whether the incoming call is an emergency call from a public safety answering point entity;

if said data indications do not indicate that the incoming call is an emergency call from the public safety answering point, then performing non-emergency call processing for the incoming call; and

if said data indications indicate that the incoming call is an emergency call, then causing the emergency call to be answered automatically by the communication device.

10. A mobile communication device, comprising:

one or more processors;

a wireless transceiver coupled to the one or more processors and configured for communications via a wireless communication network;

a user interface coupled to the one or more processors;

the one or more processors being configured for;

receiving an incoming call message for an incoming call, the incoming call message having data indications indicating whether the incoming call is an emergency call from a public safety answering point entity;

if said data indications do not indicate that the incoming call is an emergency call from the public safety answering point, then performing non-emergency call processing for the incoming call; and

if said data indications indicate that the incoming call is an emergency call, then causing the emergency call to be answered automatically by the communication device.

11. The mobile communication device of claim 10, wherein the emergency call is answered automatically without detecting a manual answer signal via a user interface of the communication device.

12. The mobile communication device of claim 10, wherein the one or more processors are further configured for:

if said data indications indicate that the incoming call is an emergency call, then refraining from producing an audible alert at the communication device for alerting of the emergency call.

13. The mobile communication device of claim 10, wherein the one or more processors are further configured for:

causing a mobile identifier which identifies the communication device to be transmitted via a communication network to the public safety answering point entity; and

wherein said receiving the incoming call message comprises receiving an incoming call message addressed to the mobile identifier.

14. The mobile communication device of claim 10, wherein the one or more processors are further configured for:

if the data indications indicate that the incoming call is the emergency call, then refraining from performing a DR (ALERT) process and a U7 CALL RECEIVED process when answering the emergency call.

15. The mobile communication device of claim 10, wherein the user interface of the communication device comprises a display, a speaker, and a microphone, and wherein the one or more processors are further configured for causing the emergency call to be answered automatically by the communication device by automatically enabling the speaker to produce audible signals from the public safety answering point entity and automatically enabling the microphone to receive audible signals at the communication device.

16. The mobile communication device of claim 10, wherein the communication device has a handset talk mode and a speakerphone talk mode, the one or more processors being further configured for:

if the data indications indicate that the incoming call is an emergency call, then enabling the speakerphone talk mode of the communication device without detecting a manual speakerphone activation signal via the user interface.

17. A method in a wireless communication network, the method comprising:

producing an incoming call message for an incoming call to a communication device;

if the incoming call is a non-emergency call, setting data indications in the incoming call message for instructing the communication device to perform non-emergency call processing; and

otherwise, if the incoming call is an emergency call from a public safety answering point entity, then setting the data indications in the incoming call message for instructing the communication device to automatically answer the emergency call; and

sending, to the communication device via the wireless network, the incoming call message having the data indications set therein.

18. The method of claim 17, wherein the wireless communication network comprises a cellular telecommunications network.

19. The method of claim 17, wherein setting the data indications in the incoming call message for instructing the communication device to automatically answer the emergency call further comprises instructing the communication device to automatically answer without detecting a manual answer signal via a user interface of the communication device.

20. The method of claim 17, wherein setting the data indications in the incoming call message for instructing the communication device to automatically answer the emergency call further comprises instructing the communication device to automatically answer while refraining from producing an audible alert at the communication device for alerting of the emergency call. incoming call message is for the emergency call back.
