Abstract

A method and apparatus to provide a scheduler comprising determining a current use characteristic for the mobile device based on motion information and active applications, and scheduling a task based on the current use characteristics.

Claims

1. A method comprising:

determining a current use characteristic for a mobile device including use of a plurality of resources based on one or more currently active applications and motion information, the resources including one or more of a user interface, storage bandwidth, volatile memory, non-volatile memory, and network bandwidth; and

determining a future use characteristic for the mobile device including use of the plurality of resources based on the one or more currently active applications and an expected future motion information; and

scheduling a future task based on the current use characteristics and the predicted future use characteristics and an availability of the one or more resources used by the future task.

2. The method of claim 1, further comprising:

scheduling the task to be immediately executed, when the task utilizes resources not currently used by the currently active applications.

3. The method of claim 1, further comprising:

identifying a priority for the future task;

determining a conflict between the currently active application and the task; and

when the task is a higher priority than the currently active application, reducing resource availability to the currently active application while maintaining the currently active application.

4. The method of claim 3, wherein when the task is the higher priority, and insufficient resources are available, terminating the currently active application.

5. The method of claim 4, wherein when the existing operation is terminated, the existing operation is placed on a future task list to be executed when the resource becomes available again.

6. The method of claim 1, further comprising:

prioritizing tasks based on resource use and application profile.

7. The method of claim 1, wherein the task is transmitting data to a server, and wherein the data transmission task is scheduled when the motion information and the currently active applications indicate that the device is idle.

8. The method of claim 7, wherein the data call is for one or more of:

uploading, downloading, and synchronizing data with a server.

9. The method of claim 7, wherein the device is idle when the device is motionless, and no user interaction with the device is occurring.

10. The method of claim 7, wherein the device is idle when the device is motionless and no voice call is being made.

11. A mobile device including a network connection comprising:

a motion sensor to obtain motion information;

a processor to implement an active application detector to detect a current use characteristic for the mobile device based on one or more currently active applications and the motion information;

the processor further to identify a future use characteristic for the mobile device including use of the plurality of resources based on the one or more currently active applications and an expected future motion information; and

a scheduler to schedule a future task based on the current use characteristics and the predicted future use characteristics and an availability of the one or more resources used by the future task, the resources including one or more of a user interface, storage bandwidth, volatile memory, non-volatile memory, and network bandwidth.

12. The mobile device of claim 11, further comprising:

the scheduler to schedule the task to be immediately executed, when the task utilizes resources not currently used by the currently active applications.

13. The mobile device of claim 11, further comprising:

a prioritizer to determine a conflict between the currently active application and the task; and

when the task is a higher priority than the currently active application, a resource restrictor to reducing resource availability to the currently active application.

14. The mobile device of claim 13, wherein reducing resource availability comprises terminating the currently active application.

15. The mobile device of claim 14, wherein when the existing operation is terminated, the existing operation is placed on a future task list to be executed when the resource becomes available again.

16. The mobile of claim 11, further comprising:

the scheduler to prioritize tasks based on resource use and application profile.

17. The mobile device of claim 11, wherein the task is transmitting data to a server, and wherein the data transmission task is scheduled when the motion information and the currently active applications indicate that the device is idle.

18. The mobile device of claim 17, wherein the data call is for one or more of:

uploading, downloading, and synchronizing data with a server.

19. The mobile device of claim 17, wherein the device is idle when one of the following is occurring:

the device is motionless and no user interaction with the device is occurring, or when the device is motionless and no voice call is being made.

20. A mobile device including a network connection comprising:

a processor designed to implement a motion information logic to receive motion information from a mobile device, and to determine a current use characteristic and to determine an expected future use characteristics including use of a plurality of resources and an expected future motion information;

an active application detector to adjust the current use characteristic for the mobile device based on one or more currently active applications and motion information;

a scheduler to receive a task to be scheduled, the task comprising a data transmission; and

the scheduler to schedule the task based on the current use characteristics and predicted future use characteristics and expected resource availability of one or more resources used by the future task, and the currently active applications and the expected future motion information.
