    • A method for switching system state and a portable terminal. The method is applied to a portable terminal comprising a first system and a second system. The second system has a second control module provided therein. The method comprises: obtaining, by the second system, state information of the first system through the second control module when at least one of the first system and the second system is in an inactive state; receiving, by the second control module, a system state switching event; switching, by the second control module, the second system to a state corresponding to the state information of the first system based on the state information of the first system. According to the embodiments of the present invention, when the system state is to be switched, it is not necessary that both systems are in the active state. Rather, the state information can be transmitted between the systems in the inactive state by using a control module provided in one or both of the systems, and the power consumption of the portable terminal can be reduced.
    • 一种用于切换系统状态和便携式终端的方法。 该方法应用于包括第一系统和第二系统的便携式终端。 第二系统具有设置在其中的第二控制模块。 该方法包括:当第一系统和第二系统中的至少一个处于非活动状态时,由第二系统获得通过第二控制模块的第一系统的状态信息; 由所述第二控制模块接收系统状态切换事件; 基于第一系统的状态信息,由第二控制模块将第二系统切换到与第一系统的状态信息对应的状态。 根据本发明的实施例,当要切换系统状态时,两个系统都不必处于活动状态。 相反,可以通过使用在一个或两个系统中提供的控制模块来在处于非活动状态的系统之间传送状态信息,并且可以减少便携式终端的功耗。
