Abstract:
A portable communication system ( 100 ) maintains mission critical functionality. An accessory ( 120 ) and a handset ( 130 ) are tethered and interoperate such that the accessory operates as the primary controlling device and the handset operates as a secondary device. The accessory ( 120 ) contains a main applications processor ( 102 ) that handles non-mission critical functions. The accessory further contains a mission critical processor ( 104 ) for handling mission critical functions of transmit and receive audio as well as PTT and emergency. In response to a failure of the mission critical processor ( 104 ), the mission critical functions are maintained by handing over the mission critical functions to the non-controlling device in a manner transparent to the user. The handover is triggered in response to status changes of the mission critical processor or as a result of battery depletion. Audio paths are re-routed through backup paths ( 146 b , 148 ) negating reliance on processors of the accessory ( 120 ).

Claim (Index 5):
A method for operating a portable communication system, comprising:\n tethering an accessory to a portable handset; operating the accessory as a primary device and the handset as a secondary device, wherein mission critical user interface features of the primary device comprising PTT, emergency, and transmit/receive (TX/RX) audio are controlled by a mission critical processor of the primary device, while the PTT and emergency are controlled by both the mission critical processor and a main application processor of the primary device; monitoring, by a watchdog timer of the primary device, for a status change indicating one or more fault conditions comprising:\n a fault at the mission critical processor of the primary device; and \n a battery depletion fault of the primary device; \n triggering, in response to the status change, a handover of control from the mission critical processor of the primary device to the secondary device, thereby maintaining the mission critical user interface features at the primary device while under the control of the secondary device.
