Patent ID: 8271048

Claim:
An operation mode switching method for a mobile terminal communication system, the mobile terminal comprising a communication processor and an application processor, wherein a mode in which the communication processor performs only a communication function is defined as a communication mode, and a mode in which the communication processor performs both the communication function and an application function is defined as an application mode, the method comprising the following steps of: acquiring, in the application mode, a switching trigger information indicating to switch to the state in which the application processor is in control; controlling the communication processor to switch from the application mode to the communication mode based on the acquired switching trigger information; uploading, by the communication processor, an application program and a user control interface after the communication processor transmits an enabling command to the application processor; enabling, by the communication processor, a communication interface and loading a serial port modulation/demodulation processing program; enabling, by the application processor, the communication interface and loading a serial port modulation/demodulation processing program; loading, by the application processor, a drive and an operating system and loading the application program and the user interface for the application processing system; and communicating, by the application processor, with the communication processor via the communication interface.
