Abstract

The embodiments of the present application provide a method and a state control apparatus as well as a portable terminal. The method is applied in a first system connected to a second system and includes: detecting, by the first system, a first event; determining a first state of the first system and a second state of the second system when the first event is a first predetermined event; obtaining a predetermined policy including a first control command and a second control command based on the first state of the first system, the second state of the second system and the first predetermined event; and controlling, by the first system, its own state based on the first control command and transmitting the second control command to the second system such that the second system is switched from the second state to a fourth state. The second system has different power consumptions in the second state and the fourth state. With the embodiments of the present application, in a portable terminal of hybrid system architecture, the system states of the first and second systems can be controlled in a coordinated manner, such that the power consumption can be reduced when both systems are operating cooperatively.

obtaining, by the first system from a plurality of predetermined policies, a corresponding policy including a first control command for the first system and a second control command for the second system based on the first state of the first system, the second state of the second system and the first predetermined event; and
the first system controlling its own state based on the first control command and transmitting the second control command to the second system such that the second system is switched from the second state to a fourth state, wherein the second system has different power consumptions in the second state and the fourth state,
wherein the first predetermined event detected by the first system comprises a predetermined event detected by the first system that causes an increased power consumption of the second system or a predetermined event detected by the first system that causes a decreased power consumption of the second system;
wherein the predetermined event detected by the first system that causes an increased power consumption of the second system comprises an event in which the first system detects that the first system needs to use a communication module of the second system;
wherein the plurality of predetermined policies comprise:
a policy to generate the first control command for controlling the first system to maintain an active state and the second control command for controlling the second system to enter an communication state when the first state of the first system and the second state of the second system are both in the active state and the first predetermined event is the event in which the first system needs to use the communication module of the second system.

2. The method of claim 1 , wherein the first system controlling its own state based on the first control command comprises:
the first system maintaining its own state based on the first control command; or
the first system switching its own state from the first state to a third state, wherein the first system has different power consumptions in the first state and the third state.

3. The method of claim 1 , wherein the plurality of predetermined policies further comprise:
a policy to generate the first control command for switching the first system from a power-off state to an active state and the second control command for switching the second system from a dormant state to an active state when the first state of the first system is in the power-off state, the second state of the second system is in the dormant state and the first predetermined event is the event in which the first system is powered on in response to a user operation; and
a policy to generate the first control command for switching the first system from a dormant state to an active state and the second control command for switching the second system from a power-off state to an active state when the first state of the first system is in the dormant state, the second state of the second system is in the power-off state and the first predetermined event is the event in which the first system is waked in response to a user operation.

4. The method of claim 1 , wherein the predetermined event detected by the first system that causes a decreased power consumption of the second system comprises at least one of:
an event in which the first system detects that the first system is powered off in response to a user operation;
an event in which the first system detects that a power level of the first and second systems is lower than a predetermined threshold; and
an event in which the first system detects that the first system needs to stop using a communication module of the second system.

5. The method of claim 4 , wherein the plurality of predetermined policies comprise:
a policy to generate the first control command and the second control command for switching the first system and the second system from an active state to a power-off state, respectively, when the first state of the first system and the second state of the second system are both in the active state and the first predetermined event is the event in which the power level of the first and second systems is lower than the predetermined threshold;
a policy to generate the first control command for switching the first system from an active state to a power-off state and the second control command for switching the second system from a communication state to an active state when the first state of the first system is in the active state, the second state of the second system is in the communication state and the first predetermined event is the event in which the first system is powered off in response to a user operation; and/or
a policy to generate the first control command for controlling the first system to maintain an active state and the second control command for switching the second system from a communication state to an active state when the first state of the first system is in the active state, the second state of the second system is in the communication state and the first predetermined event is the event in which the first system needs to stop using the communication module of the second system.
