Abstract: A mobile communication device (100) uses a local wireless transceiver (108) to establish an asynchronous link (202) with a remote audio processor (110) which is typically operated in a low power mode and that maintains an association between the mobile communication device and remote audio processor. When the mobile communication device receives an incoming call page (210), the mobile communication device initiates a synchronous link with the remote audio processor, and responds to the incoming call page at a time when the call will be connected only after the synchronous link is established.

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.
