Abstract

A method of and an electronic device for performing a power-saving mode in the electronic device, according is provided. The method includes driving at least one processor; detecting a command for switching to a power-saving mode; and if the command for switching to the power saving mode is detected, limiting operations of the at least one processor to block set functions other than a power saving call function in accordance with at least one set power saving scheme.

First claim

1 . A method of performing a power saving mode in an electronic device, the method comprising:
driving at least one processor; detecting a command for switching to a power saving mode; and if the command for switching to the power saving mode is detected, limiting operations of the at least one processor to block set functions other than a power saving call function in accordance with at least one set power saving scheme.

2 . The method of claim 1 , further comprising, if the command for switching to the power saving mode is an emergency message received externally:
extracting at least one piece of disaster-related information by parsing the emergency message; and switching to an emergency mode based on the extracted disaster-related information.

3 . The method of claim 1 , further comprising, if the command for switching to the power saving mode is detected, displaying a screen configured to use at least one of a control of brightness of a screen of a display unit, of switch the screen of the display unit to a gray mode, switch a home screen of the display unit to a home screen of a minimum function, and deactivate other applications except for a set necessary applications.

4 . The method of claim 3 , wherein the set necessary application includes at least one of a phone call application, a message application, and a web browser application.

5 . The method of claim 1 , wherein the at least one processor includes at least one of a call processor (CP) and an application processor (AP).

6 . The method of claim 1 , wherein the command for switching to the power saving mode is one of a request for switching a mode by a user and a reception of an emergency message from a cell broadcast message service (CBS) server or an earthquake and tsunami warning service (ETWS) server through a mobile communication protocol.

7 . The method of claim 1 , further comprising, if the at least one of the set power saving schemes is a network limiting scheme for limiting transmission of information based on a network, fixing a network function (NAT) by a call processor (CP) in order to increase a sleep period of a modem or blocking transmission of network information received from the network to an application processor (AP) by the CP if a screen is turned off.

8 . The method of claim 1 , further comprising, if the at least one of the set power saving schemes is a network limiting scheme for limiting transmission of information based on a network:
deleting a route table to block mobile data transmission/reception between an application processor (AP) and a call processor if a screen is turned off; and if the turned off screen is subsequently turned on, reconstructing the route table.

9 . The method of claim 1 , further comprising, if the at least one the set power saving scheme is a process limiting scheme for limiting the use of a background in a screen off state:
halting a process in application processor (AP) if the screen is turned off; and if the turned off screen is subsequently turned on, performing the process.

10 . An electronic device for performing a power saving mode, the electronic device comprising:
a display unit configured to display a power saving screen if a command for switching to a power saving mode is detected, the display unit is functionally connected to the electronic device; and a control unit comprising a call processor (CP) configured to control a power saving call-related function and an application processor that controls other functions except for the power saving call-related function, wherein the control unit is configured to control to limit an operation of at least one of the call processor (CP) and the application processor (AP) to block at least some of the other functions in accordance with at least one set power saving scheme if the command for switching to the power saving mode is detected.

11 . The electronic device of claim 10 , wherein, if the command for switching to the power saving mode is an emergency message received externally, the control unit is configured to parse the emergency message to extract at least piece of disaster-related information and switch to an emergency mode based on the extracted disaster-related information.

12 . The electronic device of claim 11 , wherein the set necessary application includes at least one of a phone call application, a message application, and a web browser application.

13 . The electronic device of claim 10 , further comprising a power saving screen configured to use at least one of a control of brightness of a screen of a display unit, switch screen of the display unit to a gray mode, switch a home screen of the display unit to a home screen of a minimum function, and deactivate another application except for a set necessary applications.

14 . The electronic device of claim 10 , wherein the command for switching to the power saving mode is one of a request for switching a mode by a user and a reception of an emergency message from a cell broadcast message service (CBS) server or an earthquake and tsunami warning service (ETWS) server through a mobile communication protocol.

15 . The electronic device of claim 10 , wherein, if the at least one the set power saving scheme is a network limiting scheme for limiting transmission of information based on a network, a call processor (CP) is configured to perform at least one of an operation of fixing a network function (NAT) in order to increase a sleep period of a if a screen is turned off, an operation of filtering the information received from a network to prevent the information from being transmitted to an application processor (AP) if the screen is turned off, and if a route table is deleted to block mobile data transmission/reception between the AP and the CP if the screen is turned off and then subsequently turned on, reconstructing the route table.
