Abstract

The present disclosure relates to an apparatus and a method for managing power in an electronic device. According to the various embodiments of the present disclosure, a method for operating an electronic device comprises determining a wake-up period based on at least one of a received signal strength and a state of the electronic device, and controlling a wireless communication module of the electronic device based on the wake-up period.

First claim

The invention claimed is:

1. A method of operating an electronic device, the method comprising:
determining whether a wireless communication module of the electronic device is stopped based on a state of the electronic device;
in case the wireless communication module is not stopped, determining whether a video streaming application is running;
in case the video streaming application is running, determining whether a display of the electronic device is turned off;
in case the display is turned off, determining whether a received signal strength of an access point (AP) currently involved in communication with the electronic device is greater than a threshold;
in case the received signal strength is greater than the threshold, calculating an average bit rate of a video content of the video streaming application and a current transmission rate;
in case the current transmission rate is 1.5 times or higher than the average bit rate, determining a wake-up period based on the average bit rate and the current transmission rate, wherein the wake-up period is based on a beacon period;
controlling the wireless communication module based on the wake-up period; and
maintaining the wireless communication module in an awake state in case the display is not turned off, in case the received signal strength is not greater than the threshold or in case the current transmission rate is not 1.5 times or higher than the average bit rate.

2. The method of claim 1 , wherein the state of the electronic device comprises:
application network usage information.

3. The method of claim 2 , further comprising:
controlling the wireless communication module of the electronic device further based on a beacon count that represents a number of wake-ups in a sleep mode of the electronic device if a received signal strength exceeds a predefined first threshold value and a movement speed of the electronic device is less than or equal to a predefined second threshold value.

4. The method of claim 1 , further comprising:
outputting a notification of a received packet in an active mode of the electronic device;
detecting a user input responsive to the notification; and
controlling the wireless communication module of the electronic device further based on the user input.

5. The method of claim 1 , further comprising:
executing a power save mode of the wireless communication module based on the wake-up period.

6. An electronic device comprising:
a wireless communication module;
display; and
a first processor configured to:
determine whether the wireless communication module is stopped based on a state of the electronic device,
in case the wireless communication module is not stopped, determine whether a video streaming application is running,
in case the video streaming application is running, determine whether the display is turned off,
in case the display is turned off, determine whether a received signal strength of an access point (AP) currently involved in communication with the electronic device is greater than a threshold,
in case the received signal strength is greater than the threshold, calculate an average bit rate of a video content of the video streaming application and a current transmission rate,
in case the current transmission rate is greater than the average bit rate, determine a wake-up period based on the average bit rate and the current transmission rate, wherein the wake-up period is based on a beacon period,
control the wireless communication module based on the wake-up period,
maintain the wireless communication module in an awake state in case the display is not turned off, in case the received signal strength is not greater than the threshold or in case the current transmission rate is not 1.5 times or higher than the average bit rate.

7. The electronic device of claim 6 , wherein the state of the electronic device comprises:
application network usage information.

8. The electronic device of claim 7 , further comprising a second processor configured to control the wireless communication module of the electronic device further based on a beacon count that represents a number of wake-ups in a sleep mode of the electronic device if a received signal strength exceeds a predefined first threshold value and a movement speed of the electronic device is less than or equal to a predefined second threshold value.

9. The electronic device of claim 6 , wherein the first processor is further configured to:
output a notification of a received packet in an active mode of the electronic device,
detect a user input responsive to the notification, and
control the wireless communication module of the electronic device further based on the user input.

10. The electronic device of claim 6 , wherein the first processor is further configured to execute a power save mode of the wireless communication module based on the wake-up period.

11. The electronic device of claim 6 , wherein the wireless communication module is further configured to change a current wake-up period of the wireless communication module to the determined wake-up period based on a control of the first processor.
