Abstract

A processing device identifies a plurality of wake-ups that are requested by one or more applications and applies a wake-up restriction policy to the plurality of wake-ups. Applying the wake-up restriction policy to a wake-up of the plurality of wake-ups comprises determining whether the wake-up conforms to the wake-up restriction policy. Responsive to determining that the wake-up conforms to the wake-up restriction policy, the processing device permits the wake-up to activate at least one of the processing device or an additional processing device. Responsive to determining that the alarm wake-up will violate the wake-up restriction policy, the processing device prevents the wake-up from later activating at least one of the processing device or the additional processing device.

First claim

What is claimed is:

1. A mobile device comprising:
a processing device to:
determine a first subset of a plurality of applications;
determine a second subset of the plurality of applications;
perform a transmission control protocol (TCP) reset for each application of the first subset; and
add an entry for each application in the second subset to a list comprising applications to be restricted by a network wake-up filter, wherein an entry for a first application in the second subset comprises a source identifier associated with the first application; and

a network component that includes the network wake-up filter and is operatively coupled to the processing device, the network component to:
receive a packet from a remote server;
identify a source of the packet;
determine that the source identifier in the list matches the source; and
drop the packet.

2. The mobile device of claim 1 , wherein the network component is further to:
receive a second packet from a second remote server;
identify a second source of the second packet;
determine that the second source does not match any source identifier in the list;
activate the processing device; and
forward the second packet to the processing device.

3. The mobile device of claim 1 , wherein the processing device is further to:
determine statistics about a plurality of network wake-up events associated with the plurality of applications; and
identify the second subset of the plurality of applications as applications that are associated with a highest number of network wake-up events based on the statistics.

4. The mobile device of claim 1 , wherein the network component comprises a wireless component.

5. The mobile device of claim 1 , wherein dropping the packet enables the packet to be deleted without the processing device being informed of the packet.

6. The mobile device of claim 1 , wherein the network component comprises a wireless network interface controller (WNIC), and wherein the processing device and the WNIC are logics of a single integrated circuit.

7. The mobile device of claim 1 , wherein the processing device is further to update firmware of the network component to include the network wake-up filter comprising the list.

8. A method comprising:
gathering, by a processing device, information about device wake-up events associated with a plurality of applications, wherein the device wake-up events comprise Wi-Fi wake-up events that activate the processing device responsive to receipt of packets over Wi-Fi;
determining, by the processing device, statistics about the device wake-up events associated with the plurality of applications;
identifying a first subset of the plurality of applications that are associated with at least a first percentage of the device wake-up events;
performing a transmission control protocol (TCP) reset for each application of the first subset;
identifying a second subset of the plurality of applications that are associated with at least a second percentage of the device wake-up events;
applying a wake-up restriction policy by adding an entry for each application in the second subset to a list comprising applications to be restricted by a network wake-up filter, wherein an entry for a first application in the second subset comprises a source identifier associated with the first application;
receiving a packet from a remote server by a Wi-Fi component that includes the network wake-up filter;
identifying a source of the packet;
determining that the source identifier in the list matches the source; and
dropping the packet by the Wi-Fi component without waking the processing device, wherein dropping the packet enables the packet to be deleted without the processing device being informed of the packet.

9. The method of claim 8 , wherein the device wake-up events further comprise alarm wake-up events that are to activate the processing device at specified times, wherein the wake-up restriction policy comprises an alarm wake-up threshold specifying an allowable number of alarm wake-ups in a time period, the method further comprising:
determining that an alarm wake-up fails to conform to the wake-up restriction policy by determining that the alarm wake-up causes a number of alarm wake-ups in the time period to exceed the alarm wake-up threshold; and
removing the alarm wake-up from an alarm wake-up schedule.

10. The method of claim 8 , further comprising:
detecting an attempt by the first application to implement a wake lock to prevent at least one of the processing device from suspending or a display from turning off; and
responsive to determining that the wake lock violates the wake-up restriction policy, preventing application of the wake lock.

11. The method of claim 8 , wherein determining the statistics comprises:
determining individual application statistics based on aggregating, for each application, device wake-up events associated with that application to determine a frequency of device wake-up events associated with that application and circumstances under which that application generates device wake-up events; and
comparing the individual application statistics to identify which of the applications are associated with a highest number of device wake-up events.

12. A computer readable storage medium having instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
determining a first subset of a plurality of applications;
determining a second subset of the plurality of applications;
performing a transmission control protocol (TCP) reset for each application of the first subset;
adding an entry for each application in the second subset to a list comprising applications to be restricted by a network wake-up filter, wherein an entry for a first application in the second subset comprises a source identifier associated with the first application;
receiving a packet from a remote server by a network component that comprises the network wake-up filter; identifying a source of the packet;

determining that the source identifier in the list matches the source; and
preventing the wake-up from activating the processing device by dropping the packet.

13. The computer readable storage medium of claim 12 , the operations further comprising:
gathering information about a plurality of previous wake-up events associated with one or more of the plurality of applications;
determining statistics about the plurality of previous wake-up events; and
creating a wake-up restriction policy based on the statistics.

14. The computer readable storage medium of claim 13 , wherein the wake-up restriction policy comprises an application specific alarm wake-up restriction policy that comprises a time period and an alarm wake-up threshold specifying an allowable number of alarm wake-ups in the time period, and wherein applying the application specific alarm wake-up restriction policy comprises:
identifying a new alarm wake-up associated with the first application;
counting a number of previous alarm wake-ups associated with the first application that are within the time period;
determining that the number of previous alarm wake-ups associated with the first application is at or above the alarm wake-up threshold; and
preventing the new alarm wake-up from activating the processing device.

15. The computer readable storage medium of claim 13 , wherein the wake-up restriction policy comprises an application specific alarm wake-up restriction policy that comprises a time period and an alarm wake-up threshold specifying an allowable number of
