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 1):
A portable communication system, comprising:\n a primary controlling device comprising a battery powered accessory having an application processor; a secondary device comprising a battery powered two-way radio handset tethered to the primary controlling device; and the portable communication system maintaining mission critical functionality via four modes of failure-safe switching operation, comprising:\n fail-safe switching of a transmit audio path from the primary controlling device into the secondary device in response to a partial or full system failure of the primary controlling device; \n fail-safe switching of a receive audio path from the primary device into the secondary device in response to a partial or full system failure of the primary device. \n failure-safe switching of a main power supply of the primary controlling device to a secondary power supply of the secondary device; and \n failure-safe switching of an emergency indicator system of the primary controller device to the secondary device.
