Claim:
1. A system-state control method, applied in a portable terminal comprising a first system and a second system, in which the first system has a first interface and the second system has a second interface, and in which the first system and the second system implement connection or disconnection via the first interface and the second interface, the method comprises: when the first system and the second system enter a connected state from a disconnected state, the first system and the second system interact on their respective system-state information; the first system and the second system, based on the system-state information, perform control to the system state according to a predetermined strategy, wherein the first system is a system which is constituted by a first hardware system and a first operating system based on the first hardware system, the second system is a system which is constituted by a second hardware system and a second operating system based on the second hardware system, and when the first system and the second system are connected, the first system and the second system share some hardware devices, the second hardware system includes a display screen, when the first system and the second system are disconnected, the display screen is used by the second system, when the first system and the second system are connected with each other, the display screen is used by the first system, wherein the predetermined strategy comprises when the first system and the second system are in a same system state as they are in a disconnected state, then after entering a connected state, their respective system states are kept unchanged; said being in a same system state includes being simultaneously in a work state, or being simultaneously in a non-work state; when one system from the first system and the second system is in a work state while the other system is in a non-work state as they are in a disconnected state, then after entering a connected state, the system in a non-work state enters a work state automatically.
