Abstract

In a power-on/off management method of a communication device, a display screen of the communication device is powered off, and a signal transmitting function of the communication device is suspended, when a power key of the communication device is pressed upon the condition that the communication device is in a power-on state. A duration time of how long the display screen is powered off is determined, and the communication device is activated according to the duration time when the power key is pressed upon the condition that the display screen is powered off.

Claims

1. A power-on/off management method of a communication device, the method comprising:

powering off a display screen of the communication device, and suspending a signal transmitting function of the communication device, when a power key of the communication device is pressed upon the condition that the communication device is in a power-on state;

determining a duration time of how long the display screen is powered off; and

activating the communication device according to the duration time when the power key is pressed upon the condition that the display screen is powered off.

2. The method according to claim 1, further comprising:

triggering the communication device to implement a shutdown program to power off the communication device, when the duration time exceeds a preset maximum threshold time.

3. The method according to claim 2, wherein the communication device is activated by:

rebooting up an operating system of the communication device, powering on the display screen, and activating the signal transmitting function of the communication device, if the duration time is less than a preset minimum threshold time;

powering on the display screen, and activating the signal transmitting function of the communication device, if the duration time is greater than or equal to the minimum threshold time, and less than the maximum threshold time;

or

powering on all hardware of the communication device, and booting up the operating system, if the duration time is greater than or equal to the maximum threshold time.

4. The method according to claim 3, further comprising:

displaying a boot animation on the display screen to simulate a booting process of the communication device, when the display screen is powered on.

5. A communication device, comprising:

a display screen;

at least one processor;

a storage system; and

one or more programs stored in the storage system and being executable by the at least one processor, the one or more programs comprising;

a screen control module operable to power off the display screen, and suspend a signal transmitting function of the communication device, when a power key of the communication device is pressed upon the condition that the communication device is in a power-on state;

a timing module operable to determine a duration time of how long the display screen is powered off; and

an execution module operable to activate the communication device according to the duration time when the power key is pressed upon the condition that the display screen is powered off.

6. The communication device according to claim 5, wherein the timing module is further operable to trigger the communication device to implement a shutdown program to power off the communication device, when the duration time exceeds a preset maximum threshold time.

7. The communication device according to claim 6, wherein the communication device is activated by:

rebooting up an operating system of the communication device, powering on the display screen, and activating the signal transmitting function of the communication device, if the duration time is less than a preset minimum threshold time;

powering on the display screen, and activating the signal transmitting function of the communication device, if the duration time is greater than or equal to the minimum threshold time, and less than the maximum threshold time;

or

powering on all hardware of the communication device, and booting up the operating system, if the duration time is greater than or equal to the maximum threshold time.

8. The communication device according to claim 7, wherein the execution module is further operable to display a boot animation on the display screen to simulate a booting process of the communication device, when the display screen is powered on.

9. A non-transitory storage medium storing a set of instructions, the set of instructions capable of being executed by a processor of a communication device, to perform a power-on/off management method of the communication device, the method comprising:

powering off a display screen of the communication device, and suspending a signal transmitting function of the communication device, when a power key of the communication device is pressed upon the condition that the communication device is in a power-on state;

determining a duration time of how long the display screen is powered off; and

activating the communication device according to the duration time when the power key is pressed upon the condition that the display screen is powered off.

10. The storage medium as claimed in claim 9, wherein the method further comprises:

triggering the communication device to implement a shutdown program to power off the communication device, when the duration time exceeds a preset maximum threshold time.

11. The storage medium as claimed in claim 10, wherein the communication device is activated by:

rebooting up an operating system of the communication device, powering on the display screen, and activating the signal transmitting function of the communication device, if the duration time is less than a preset minimum threshold time;

powering on the display screen, and activating the signal transmitting function of the communication device, if the duration time is greater than or equal to the minimum threshold time, and less than the maximum threshold time;

or

powering on all hardware of the communication device, booting up the operating system, if the duration time is greater than or equal to the maximum threshold time.

12. The storage medium as claimed in claim 11, further comprising:

displaying a boot animation on the display screen to simulate a booting process of the communication device, when the display screen is powered on.
