Abstract

A power saving mode control method and device for multiple operating systems include: setting corresponding power saving modes for each of the multiple operating systems in advance; and determining an operating system of which a power saving mode is triggered, and causing the operating system of which the power saving mode is triggered to enter the corresponding power saving mode.

First claim

What is claimed is:

1. A method of power saving mode control for multiple operating systems, comprising:
setting a first power saving mode for a first operating system and a second power saving mode for a second operating system in advance, wherein the first and second power saving modes both control a non-exclusive resource shared by the first and second operating systems, wherein a first level of the first power saving mode performs a power saving setting of at least one hardware or software resource used for the first operating system, wherein a second level of the first power saving mode causes the first operating system to enter a standby mode, thereby merely reserving designated functions as wake-up sources of the first operating system, and wherein a third level of the first power saving mode shuts down the first operating system, thereby releasing hardware and software resources exclusively used for the first operating system;
simultaneously operating the first operating system in the first power saving mode and the second operating system in the second power saving mode; and
determining how to control the non-exclusive resource when there is a conflict between the first power saving mode and the second power saving mode.

2. The method of claim 1 , wherein the first power saving mode is set as one of the first level, the second level, or the third level and the second power saving mode is set as one of a first level, a second level, or a third level in advance.

3. The method of claim 2 , wherein the second level of the second power saving mode causes the second operating system to enter a standby mode, thereby merely reserving designated functions as wake-up sources of the second operating system, and wherein the third level of the second operating system shuts down the second operating system, thereby releasing hardware and software resources exclusively used for the second operating system.

4. The method of claim 1 , wherein the first operating system is a security system and the second operating system is a common system, and wherein the security system has a security level higher than the common system.

5. The method of claim 4 , wherein a first contact is associated with the security system, wherein a second contact is associated with the common system, wherein the security system is waked up when the first contact is called, and wherein the common system is waked up when the second contact is called.

6. The method of claim 1 , wherein determining how to control the non-exclusive resource when there is a conflict between the first power saving mode and the second power saving mode comprises:
determining which of the first operating system or the second operating system is running in a foreground.

7. The method of claim 6 , further comprising:
based on a determination that the first operating system is running in the foreground, controlling the non-exclusive resource according to the first power saving mode; and
based on a determination that the second operating system is running in the foreground, controlling the non-exclusive resource according to the second power saving mode.

8. The method of claim 6 , further comprising:
based on a determination that the first operating system is running in the foreground, controlling only hardware or software resources used exclusively by the second operating system according to the second power saving mode.

9. The method of claim 6 , further comprising:
based on a determination that the first operating system is running in the foreground, prompting a user whether to control hardware or software resources used exclusively by the second operating system according to the second power saving mode.

10. The method of claim 6 , further comprising:
based on a determination that the first operating system is running in the foreground, notifying a user that the second power saving mode cannot be entered.

11. A terminal, comprising:
a memory; and
a processor configured to execute instructions stored in the memory to:
set a first power saving mode for a first operating system and a second power saving mode for a second operating system in advance, wherein the first and second power saving modes control a non-exclusive resource shared by the first and second operating systems, wherein a first level of the first power saving mode performs a power saving setting of at least one hardware or software resource used for the first operating system, wherein a second level of the first power saving mode causes the first operating system to enter a standby mode, thereby merely reserving designated functions as wake-up sources of the first operating system, and wherein a third level of the first power saving mode shuts down the first operating system, thereby releasing hardware and software resources exclusively used for the first operating system;
simultaneously operate the first operating system in the first power saving mode and the second operating system in the second operating system mode; and
determine how to control the non-exclusive resource when there is a conflict between the first power saving mode and the second power saving mode.

12. The terminal of claim 11 , wherein the first power saving mode is set as one of the first level, the second level, or the third level and the second power saving mode is set as one of a first level, a second level, or a third level in advance.

13. The terminal of claim 12 , wherein the first level of the second power saving mode performs a power saving setting of at least one hardware or software resource used for the second operating system, wherein the second level of the second power saving mode causes the second operating system to enter a standby mode, thereby merely reserving designated functions as wake-up sources of the second operating system, and wherein the third level of the second operating system shuts down the second operating system, thereby releasing hardware and software resources exclusively used for the second operating system.

14. The terminal of claim 11 , wherein the first operating systems is a security system and the second operating system is a common system, and wherein the security system has a security level higher than the common system.

15. The terminal of claim 14 , wherein a first contact is associated with the security system, wherein a second contact is associated with the common system, wherein the security system is waked up when the first contact is called, and wherein the common system is waked up when the second contact is called.

16. The terminal of claim 11 , wherein the instructions to determine how to control the non-exclusive resource when there is a conflict between the first power saving mode and the second power saving mode comprise:
determine which of the first operating system or the second operating system is running in a foreground.

17. The terminal of claim 16 , wherein the processor is further configured to execute instructions stored in the memory to:
based on a determination that the first operating system is running in the foreground, control the non-exclusive resource according to the first power saving mode; and
based on a determination that the second operating system is running in the foreground, control the non-exclusive resource according to the second power saving mode.

18. The terminal of claim 16 , wherein the processor is further configured to execute instructions stored in the memory to:
based on a determination that the first operating system is running in the foreground, control only hardware or softwa
