Abstract
The present invention provides a method for implementing diversity for a dual-mode communication unit in a communication system. The communication system includes a first transceiver utilizing a first air interface and a second transceiver utilizing a second air interface distinct from the first air interface. The system also includes a controller that includes a selector function. The dual-mode communication unit transmits a first copy of bearer data to the first transceiver utilizing the first air interface. The dual-mode communication unit transmits a second copy of the bearer data to the second transceiver utilizing the second air interface. The first transceiver and the second transceiver sending the copy of the bearer data to the controller. The first transceiver and the second transceiver also send a quality metric to the controller. The controller selects a preferred copy of the bearer data based at least in part upon the quality metrics.
