Patent ID: 8805437

Claim:
A method of a mobile device comprising a first mode system and a second mode system, the method comprising: determining a status of the first and second mode systems; upon the determination that both of the first and second mode systems are in a working status, using the first mode system to control a first power amplifier of the first mode system to transmit power signals to an antenna for broadcasting the power signals to a base station, informing the second mode system that the first power amplifier is transmitting the power signals, and controlling the second mode system to enter into a mixed mode, wherein the mixed mode allows both of the first and second mode systems to work synchronously; and upon the determination that the second mode system is in a working status and the first mode system is in a required to work status, using the first mode system to inform the second mode system to enter into the mixed mode, controlling the first mode system to inform a second power amplifier of the second mode system to transmit power signals to the antenna, and enabling both of the first and second mode systems to work synchronously according to the mixed mode.
