METHOD AND APPARATUS FOR PERFORMING POWER MANAGEMENT FUNCTIONS

1 . A method for performing power management functions on a mobile device, the method comprising:

detecting a pattern of push events on one or more buttons of the mobile device;

determining whether the detected pattern matches a stored pattern; and

performing a predetermined power management function on the mobile device when the detected pattern matches the stored pattern wherein the predetermined function is associated with the stored pattern.

2 . The method of claim 1 , wherein detecting a pattern of push events on the one or more buttons of the mobile device further comprises detecting a pattern of push events on the one or more buttons of the mobile device within a predefined time period.

3 . The method of claim 2 , wherein the one or more buttons includes at least one of a power button, a volume up button, a volume down button, a camera button, a lock button or any other button on the mobile device with alternate primary functionality.

4 . The method of claim 2 , wherein the one or more buttons is a dedicated button on the mobile device for performing power management functions.

5 . The method of claim 1 , wherein detecting the pattern of push events on the one or more buttons comprises determining a number of push events, duration of each push event and a time interval between each push event on the one or more buttons of the mobile device.

6 . The method of claim 1 , wherein the stored pattern represents a predefined number of push events on the one or more buttons of the mobile device, predefined maximum and minimum duration of each push event and a predefined maximum and minimum time interval between each push event on the one or more buttons of the mobile device.

7 . The method of claim 6 , wherein the predefined number of push events on the one or more buttons and a predefined maximum and minimum time interval between multiple push events on the one or more buttons is customized by a user of the mobile device.

8 . The method of claim 6 , wherein determining whether the detected pattern matches the stored pattern comprises:

determining whether the determined number of push events matches the predefined number of push events on the one or more buttons of the mobile device;

determining whether the determined duration of each push event is less than a predefined maximum duration and greater than a predefined minimum duration of push events on the one or more buttons of the mobile device; and

determining whether the determined time interval between each push event on at least the button is less than the predefined maximum time interval and greater than minimum time interval.

9 . The method of claim 1 , wherein the predetermined action includes activating the mobile device, muting the mobile device, resetting the mobile device, and adjusting brightness of a display of the mobile device.

10 . The method of claim 1 , wherein the predetermined action associated with the stored pattern is defined by at least one of a mobile device user, a mobile device owner, a service provider, or a manufacturer of the mobile device.

11 . The method of claim 1 , further comprising:

notifying the user upon determining whether the detected pattern matches the stored pattern.

12 . A mobile device comprising:

a controller configured to:

detect a pattern of push events on one or more buttons of the mobile device,

determine whether the detected pattern matches a stored pattern, and

sending a signal to a main processor when the detected pattern matches the stored pattern; and

the main processor coupled to the controller, the main processor configured to:

perform a predetermined power management function on the mobile device upon receiving the signal from the controller wherein the predetermined action is associated with the stored pattern.

13 . The mobile device of claim 12 , wherein the controller is a separate logic element in the mobile device capable of detecting the pattern of push events on the one or more buttons of the mobile device when the mobile device is powered off.

14 . The mobile device of claim 12 , wherein the controller is further configured to detect a pattern of push events on the one or more buttons of the mobile device within a predefined time period.

15 . The mobile device of claim 12 , wherein the button includes at least one of a power button, a volume up button, a volume down button, a camera button, and a lock button on the mobile device.

16 . The mobile device of claim 12 , wherein detecting the pattern of push events on the one or more buttons comprises determining a number of push events, duration of each push event and a time interval between each push event on the one or more buttons of the mobile device.

17 . The mobile device of claim 12 , wherein the stored pattern represents a predefined number of push events on the one or more buttons of the mobile device, predefined duration of each push event and a predefined maximum and minimum time interval between each push event on the one or more buttons of the mobile device.

18 . The mobile device of claim 12 , wherein the predetermined action includes activating the mobile device, muting the mobile device, resetting the mobile device, and adjusting brightness of a display of the mobile device.

19 . The mobile device of claim 12 , wherein the predetermined action associated with the stored pattern is defined by at least one of a mobile device user, a mobile device owner, a service provider, or a manufacturer of the mobile device.

20 . The mobile device of claim 12 , wherein the controller is further configured to:

provide an indication to a user of the mobile device when the detected pattern is different from the stored pattern.
