Abstract

A mobile device is configured to control power consumption. The mobile device includes a detector configured to detect at least one of an active input or a passive condition, where the passive condition is based on a comparison of a device state or a change in the device state to a threshold. The mobile device includes a controller configured to respond to the detected active input or passive condition by causing less than all components in the mobile device, including the display screen of the mobile device, to enter a sleep mode directly from within an in-call mode. An amount of power supplied to the display screen is reduced in the sleep mode. The operational modes of the mobile device include the sleep mode and the in-call mode, and the mobile device is configured to consume at least 4% less power in the sleep mode than in the in-call mode.

First claim

What is claimed is:

1. A mobile device configured to control power consumption, the mobile device comprising:
a display screen;
a detector configured to detect at least one of an active input or a passive condition, wherein the passive condition is determined to be present based on a comparison of a device state or a change in the device state to a threshold; and
a controller configured to perform operations in response to the detected active input or passive condition, wherein the operations include:
when the mobile device is operative in an idle mode, transition the mobile device from the idle mode to a first sleep mode in response to the detected active input or passive condition,
when the mobile device is operative in a calling mode, transition the mobile device from the calling mode to a second sleep mode in response to the detected active input or passive condition,
when the mobile device is operative in a called mode, transition the mobile device from the called mode to a third sleep mode in response to the detected active input or passive condition, or
when the mobile device is operative in an in-call mode, transition the mobile device from the in-call mode to a fourth sleep mode in response to the detected active input or passive condition,
wherein the mobile device in the first sleep mode is configured to consume less power than the idle mode, the mobile device in the second sleep mode is configured to consume less power than the calling mode, the mobile device in the third sleep mode is configured to consume less power than the called mode, and the mobile device in the fourth sleep mode is configured to consume less power than the in-call mode,
wherein the mobile device in the fourth sleep mode is configured to consume more power than the first sleep mode, the second sleep mode, or the third sleep mode,
wherein the controller is configured to transition the mobile device from the first sleep mode to the idle mode when a user wakes up the mobile device in the first sleep mode, transition the mobile device from the second sleep mode to the calling mode when the user wakes up the mobile device in the second sleep mode, transition the mobile device from the third sleep mode to the called mode when the user wakes up the mobile device in the third sleep mode, and transition the mobile device from the fourth sleep mode to the in-call mode when the user wakes up the mobile device in the fourth sleep mode.

2. The mobile device of claim 1 , wherein the mobile device includes a user key for input, wherein the active input includes an input thorough the user key.

3. The mobile device of claim 1 , wherein the passive condition includes an elapse of a predetermined time interval from a point of time when the mobile device enters into a specific operational mode.

4. The mobile device of claim 1 , wherein the controller is configured to transition the mobile device from the third sleep mode to the called mode when the mobile device receives another call signal in the third sleep mode.

5. The mobile device of claim 1 , wherein the user wakes up the mobile device in the first sleep mode, the second sleep mode, or the third sleep mode by pressing a specific button or by turning a switch on.

6. The mobile device of claim 1 , wherein the controller is configured to transition the mobile device from the calling mode to the idle mode when the user stops sending a call signal in the calling mode.

7. The mobile device of claim 1 , wherein the controller is configured to transition the mobile device from the called mode to the idle mode when the user does not accept a received call signal in the called mode.

8. The mobile device of claim 1 , wherein the controller is configured to transition the mobile device from the in-call mode to the idle mode when a phone call is terminated in the in-call mode.

9. The mobile device of claim 1 , wherein the controller is configured to transition the mobile device from the fourth sleep mode to the idle mode when a phone call is terminated in the fourth sleep mode.

10. The mobile device of claim 1 , wherein the controller is configured to transition the mobile device from the calling mode or the second sleep mode to the in-call mode when a party of a sent call signal accepts the sent call signal in the calling mode or the second sleep mode.

11. The mobile device of claim 1 , wherein the controller is configured to transition the mobile device from the called mode or the third sleep mode to the in-call mode when the user accepts a received call signal in the called mode or the third sleep mode.

12. A mobile device configured to control power consumption, the mobile device comprising:
a display screen;
a detector configured to detect at least one of an active input or a passive condition, wherein the passive condition is determined to be present based on a comparison of a device state or a change in the device state to a threshold; and
a controller configured to perform operations in response to the detected active input or passive condition, wherein the operations include:
when the mobile device is operative in an idle mode, transition the mobile device from the idle mode to a first sleep mode in response to the detected active input or passive condition,
when the mobile device is operative in a called mode, transition the mobile device from the called mode to a third sleep mode in response to the detected active input or passive condition, or
when the mobile device is operative in an in-call mode, transition the mobile device from the in-call mode to fourth sleep mode in response to the detected active input or passive condition,
wherein the mobile device in the first sleep mode is configured to consume less power than the idle mode, the mobile device in the third sleep mode is configured to consume less power than the called mode, and the mobile device in the fourth sleep mode is configured to consume less power than the in-call mode,
wherein the mobile device in the fourth sleep mode is configured to consume more power than the first sleep mode or the third sleep mode,
wherein the controller is configured to transition the mobile device from the first sleep mode to the idle mode when a user wakes up the mobile device in the first sleep mode and transition the mobile device from the called mode to the idle mode when the user does not accept a received call signal in the called mode.

13. The mobile device of claim 12 , wherein the controller is configured to transition the mobile device from the calling mode to the idle mode when the user stops sending a call signal in the calling mode.

14. The mobile device of claim 12 , wherein the controller is configured to transition the mobile device from the in-call mode to the idle mode when a phone call is terminated in the in-call mode.

15. The mobile device of claim 12 , wherein the controller is configured to transition the mobile device from the fourth sleep mode to the idle mode when a phone call is terminated in the fourth sleep mode.

16. The mobile device of claim 12 , wherein the controller is configured to transition the mobile device from the third sleep mode to the called mode when the user wakes up the mobile device in the third sleep mode, and transition the mobile device from the fourth sleep mode to the in-call mode when the user wakes up the mobile device in the fourth sleep mode.

17. The mobile device of claim 12 , wherein the controller is configured to transition the mobile device from a calling mode to a second sleep mode in response to the detected active input or passive condition a
