Data processing device and method for switching states thereof

A method for switching states of a data processing device, the data processing device including an operating system and a communication interface for communicating with another data processing device, wherein the communication interface is enabled when the operating system stays in an operating state of the operating system, and the communication interface is disabled when the operating system stays in a low-power-consumption state, said method comprising the following steps of:

• detecting whether the communication interface stays in an operating state of the communication interface and generating detection information;
• determining whether the operating system stays in the operating state of the operating system when the detection information indicates that the communication interface stays in a non-operating state of the communication interface and generating determination information;
• generating a system state frequency-reduction command when the determination information indicates that the operating system stays in the operating state of the operating system;
• and
• controlling the operating system to enter into the low-power-consumption state from the operating state of the operating system based on the system state frequency-reduction command.

A data processing device comprising an operating system and a communication interface for communicating with another data processing device, wherein the communication interface is enabled when the operating system stays in operating state of the operating system, and the communication interface is disabled when the operating system stays in a low-power-consumption state, said device further comprising:

• a detection unit for determining whether the communication interface stays in operating state of the communication interface and generating detection information;
• and
• a system state management unit, connected to the detection unit, for determining whether the operating system stays in the operating state of the operating system when the detection information indicates that the communication interface stays in the operating state of the communication interface and generating determination information, for generating a system state frequency-ascending command when the determination information indicates that the operating system stays in the low-power-consumption state, and for controlling the operating system to enter into the operating state of the operating system from the low-power-consumption state based on the system state frequency-ascending command, and controlling the communication interface to be enabled when the operating system enters into the operating state of the operating system from the low-power-consumption state.
