Abstract

A personal mobile device receives a session-request message requesting establishment an encrypted-audio session with a call-initiating device. In response, one or more call-response inquiries are presented via a user interface of the mobile device. The one or more call-response inquiries include an accessory-status inquiry with respect to an accessory to the mobile device. The mobile device receives, via the user interface, an accessory-unready indication with respect to the accessory, which is associated with the presented accessory-status inquiry. In response to receiving the accessory-unready indication, the mobile device establishes a communication link with the call-initiating device and refrains from exchanging audio data with the call-initiating device via the established communication link. The mobile device makes an accessory-ready determination and responsively establishes the encrypted-audio session at least in part by receiving encrypted-audio data from the accessory and forwarding, via the established communication link, the encrypted-audio data to the call-initiating device.

First claim

What is claimed is:

1 . A method comprising:
receiving, at a personal mobile device, a session-request message requesting establishment of an encrypted-audio session with a call-initiating device; in response to receiving the session-request message, presenting via a user interface of the personal mobile device, one or more call-response inquiries, the one or more call-response inquiries including an accessory-status inquiry with respect to an accessory to the personal mobile device; receiving, at the personal mobile device via the user interface, an accessory-unready indication with respect to the accessory, the accessory-unready indication being associated with the presented accessory-status inquiry; in response to receiving the accessory-unready indication, the personal mobile device establishing a communication link with the call-initiating device and refraining from exchanging audio data with the call-initiating device via the established communication link; and making, at the personal mobile device, an accessory-ready determination with respect to the accessory, and responsively establishing the encrypted-audio session at least in part by receiving encrypted-audio data from the accessory and forwarding, via the established communication link, the encrypted-audio data to the call-initiating device.

2 . The method of claim 1 , wherein establishing the communication link with the call-initiating device includes establishing a media session with the call-initiating device.

3 . The method of claim 1 , wherein making the accessory-ready determination with respect to the accessory includes receiving an accessory-ready indication.

4 . The method of claim 3 , wherein the accessory-ready indication is received via user interface.

5 . The method of claim 3 , wherein the accessory-ready indication is received from the accessory.

6 . The method of claim 5 , wherein the accessory-ready indication is a message indicative of a successful establishment of a connection between the accessory and the personal mobile device.

7 . The method of claim 1 , wherein making the accessory-ready determination with respect to the accessory includes determining a wireless communication link is established between the accessory and the personal mobile device.

8 . The method of claim 1 , further comprising, after receiving the accessory-unready indication, presenting, at the personal mobile device via the user interface, a follow-up accessory-status inquiry.

9 . The method of claim 1 , further comprising sending, in response to receiving the accessory-unready indication, a request-acknowledgment message to the call-initiating device.

10 . The method of claim 1 , wherein receiving the encrypted-audio data from the accessory includes receiving the encrypted-audio data from the accessory via a wireless communication link between the accessory and the personal mobile device.

11 . A communication device comprising:
a user interface; a communication interface; a processor; and a non-transitory computer-readable medium having instructions stored thereon that when executed by the processor cause the communication device to:
receive, via the communication interface, a session-request message requesting establishment of an encrypted-audio session with a call-initiating device;
in response to receiving the session-request message, present via the user interface, one or more call-response inquiries, the one or more call-response inquiries including an accessory-status inquiry with respect to an accessory to the communication device;
receive, via the user interface, an accessory-unready indication with respect to the accessory, the accessory-unready indication being associated with the presented accessory-status inquiry;
in response to receiving the accessory-unready indication, establish a communication link with the call-initiating device and refrain from exchanging audio data with the call-initiating device via the established communication link; and
make an accessory-ready determination with respect to the accessory, and responsively establish the encrypted-audio session at least in part by receiving encrypted-audio data from the accessory and forwarding, via the established communication link, the encrypted-audio data to the call-initiating device.

12 . The communication device of claim 11 , wherein establishing the communication link with the call-initiating device includes establishing a media session with the call-initiating device.

13 . The communication device of claim 11 , wherein making the accessory-ready determination with respect to the accessory includes receiving an accessory-ready indication.

14 . The communication device of claim 12 , wherein the accessory-ready indication is received via the user interface.

15 . The communication device of claim 12 , wherein the accessory-ready indication is received from the accessory.

16 . The communication device of claim 15 , wherein the accessory-ready indication is a message indicative of a successful establishment of a connection between the accessory and the personal mobile device.

17 . The communication device of claim 11 , wherein making the accessory-ready determination with respect to the accessory includes determining a wireless communication link is established between the accessory and the communication device.

18 . The communication device of claim 11 , the instructions further causing the communication device to, after receiving the accessory-unready indication, present, via the user interface, a follow--up accessory-status inquiry.

19 . The communication device of claim 11 , the instructions further causing the communication device to send, in response to receiving the accessory-unready indication, a request-acknowledgment message to the call-initiating device.

20 . The communication device of claim 11 , wherein receiving the encrypted-audio data from the accessory includes receiving the encrypted-audio data from the accessory via a wireless communication link between the accessory and the communication device.
