Abstract

A mobile communication device (100) contains a local wireless controller (114) for operating with a remote audio processor (124). The remote audio processor is used for listening to and speaking with remote parties via the mobile communication device, and operates in a mode having a relatively long latency in communicating with the mobile communication device. Upon receiving a dispatch call (306), a baseband processor (108) of the mobile communication device notifies an application processor (110) with a high priority dispatch notification (122). The high priority dispatch notification causes an active link to be established between the mobile communication device and remote audio processor sooner than if were to occur with ordinary call processing.

Claims

1. A method for establishing a wireless audio link between a mobile communication device and an associated remote audio processor, comprising:

establishing an asynchronous link between the remote audio processor and the mobile communication device;

receiving an incoming dispatch call at the mobile communication device, including audio information;

in response to receiving the incoming dispatch call, notifying the application processor of the mobile communication device with a high priority dispatch notification, performed by a baseband processor of the mobile communication device;

servicing the high priority dispatch notification at the application processor by initiating a synchronous link with the remote audio processor;

transmitting the audio information from the mobile communication device to the remote audio processor over the synchronous link.

2. A method for establishing a wireless audio link as defined in claim 1, wherein receiving the incoming dispatch call comprises receiving the incoming dispatch call from a base station of a communication system.

3. A method for establishing a wireless audio link as defined in claim 1, wherein receiving the incoming dispatch call comprises receiving the incoming dispatch call from another mobile communication device over a direct communication channel.

4. A method for establishing a wireless audio link as defined in claim 1, wherein establishing the asynchronous link and initiating the synchronous link between the mobile communication device and the remote audio processor are performed using a Bluetooth wireless interface.

5. A method for establishing a wireless audio link as defined in claim 1, further comprising terminating the synchronous link after a predetermined period of time during which no audio information is received.

6. A method for establishing a wireless audio link as defined in claim 1, wherein the application processor and baseband processor are each instantiated on a common hardware computing platform.

7. A method for establishing a wireless audio link as defined in claim 1, wherein the application processor and baseband processor are each instantiated on a different hardware computing platforms.

15. A method for establishing an active wireless communication link as defined in claim 11, wherein serving the dispatch interrupt is performed by an application processor.

8. A mobile communication device, comprising:

a communications transceiver;

a baseband processor operably coupled to the communications transceiver;

an application processor operably coupled to the baseband processor; and

a local wireless network transceiver operably coupled to one of the baseband processor and the application processor, and in communication with a remote audio processor via a wireless asynchronous link;

wherein, upon receiving a dispatch call via the communications transceiver, the baseband processor initiates a high priority dispatch notification to the application processor for causing the local wireless network transceiver to commence establishing a synchronous link with the remote audio processor over which audio information is transmitted from the mobile communication device to the remote audio processor.

9. A mobile communication device as defined in claim 8, wherein the baseband processor and application processor are each instantiated on a common hardware computing platform.

10. A mobile communication device as defined in claim 8, wherein the application processor and baseband processor are each instantiated on a different hardware computing platforms.

11. A method for establishing an active wireless communication link between a mobile communication device and a remote audio processor, comprising:

establishing a long latency link between the mobile communication device and the remote audio processor, the long latency link allowing the remote audio processor to operate in a low power mode;

receiving a dispatch call at the mobile communication device, the dispatch call including audio information from a remote party;

generating a high priority dispatch notification a baseband processor of the mobile communication device; and

servicing the high priority dispatch notification by initiating an active link between the mobile communication device and the remote audio processor.

12. A method for establishing an active wireless communication link as defined in claim 11, wherein establishing the long latency link comprises establishing an asynchronous link.

13. A method for establishing an active wireless communication link as defined in claim 11, wherein initiating the active link comprises initiating a synchronous link.

14. A method for establishing an active wireless communication link as defined in claim 11, further comprising routing the audio information to the remote audio processor over the active link.
