According to an embodiment of the present disclosure, the electronic device may be any device having a touch screen, and may be referred to as a mobile terminal, a mobile terminal, a communication terminal, a portable communication terminal, or a portable mobile terminal. For example, the electronic device may be a smart phone, a mobile phone, a game console, a television (TV), a display device, a vehicle head unit, a notebook computer, a laptop computer, a tablet computer, a personal media player (PMP), and a personal digital assistant (PDA). ), A navigation device, an ATM in a bank, a POS device in a store, and the like. Also, the electronic device according to the present invention may be a flexible device or a flexible display device.

A typical configuration of such an electronic device is for a mobile phone, and in the exemplary configuration of the electronic device, some components may be omitted or changed as necessary.

Referring to FIG. 1, the electronic device 100 includes one touch screen 190 and at least one touch screen controller 195. In the embodiment of the present invention, an example of the display unit and the display controller, for example, the touch screen 190 and the touch screen controller 195, will be described. The electronic device 100 also includes a controller 110, a communication module 120, an input / output module 160, a storage unit 175, and a power supply unit 180.

First, the controller 110 may include a bus for information communication and a processor connected to the bus for information processing. It may also include a second memory (eg, random access memory (RAM)) coupled to the bus for storing information required by the processor. The second memory may be used to store temporary information required by the processor. The electronic device 100 may further include a read only memory (ROM) connected to the bus to store static information required by the processor.

The controller 110 may control an overall operation of the electronic device 100 as a central processing unit (CPU) and perform an operation according to a method of performing a power saving mode according to various embodiments of the present disclosure. The controller 110 according to various embodiments of the present disclosure may operate to limit the performance of the CPU in the power saving mode. For this purpose, it can operate by changing CPU clock speed to internally save power. For example, a clock speed of 1.6 GHz in normal mode can be reduced to a clock speed of 1.2 GHz in power saving mode. In general, the higher the clock speed, the faster the processing speed, but more current consumption. Therefore, in the power saving mode, lowering the clock speed reduces the current consumption. In addition, as another example of a method of limiting CPU performance, it may be changed to operate as a single core. For example, performance can be limited by using at least one core when operating with eight cores and then entering a power saving mode. By limiting CPU performance in this way, current consumption can be reduced.

To this end, the controller 110 according to various embodiments of the present disclosure may be configured to include at least one processor. In an exemplary embodiment of the present invention, a case in which at least one processor includes a first processor 111 and a second processor 112 as illustrated in FIG. 1 will be described as an example. However, the first processor 111 or the second processor will be described. 112 may be implemented with one integrated processor. The first processor 111 may be a call processor (CP) that controls the overall operation of the electronic device 100, and the second processor 112 may be an application processor (AP) supporting multimedia. Can be.

The first processor 111 is responsible for power-saving call-related functions, such as telephone, message transmission and reception, and the second processor 112 is capable of smoothly executing various additional functions such as a camera function and a multimedia data playback function. It can play the role of multimedia function for control.

According to various embodiments of the present disclosure, the controller 110 drives both the first processor 111 and the second processor 112 in a normal mode, controls an operation for executing various applications under an operating system, and a power saving mode. When the switching condition is satisfied, access to some functions of the electronic device 100 may be blocked by blocking driving of at least one of the first processor 111 and the second processor 112 or limiting at least one operation in response to the power saving method. It can be controlled to operate in a restricted power saving mode.

For example, a function for which access is restricted may be controlled not to be displayed on the power saving screen, or even when a user input such as a touch input is generated for the function for which access is restricted, no operation may be performed. Alternatively, the controller 110 may disable all applications or services including an application running in the background in addition to at least one application allowed in the power saving mode. Here, the list of applications allowed in the power saving mode includes a power saving call function set as a default, and whether or not to add / delete an application may be set by the user through the setting menu.

According to various embodiments of the present disclosure, at least one of adjusting a screen brightness of a display unit, switching a screen of a display unit to a gray mode, changing a home screen of the display unit to a home screen of a minimum function, or deactivating other applications except for a set essential application The power saving screen can be configured using the. According to various embodiments of the present disclosure, when the command for switching to the power saving mode is detected, the power saving screen may be displayed on the display unit functionally connected to the electronic device.

According to various embodiments of the present disclosure, the controller 110 may store information on power saving items to limit the use in order to limit the use of functions related to battery consumption in the power saving mode. For example, in the power saving mode, only the minimum functions necessary for the electronic device 100 may be left and the remaining functions may be limited in order to minimize the power consumed by the electronic device 100. For example, other functions may be disabled, leaving only the power saving call function associated with the call, message reception, and the like. In addition, the screen displayed through the touch screen 190 may be switched to a power saving mode in which power is minimally consumed.

According to various embodiments of the present invention, the entry into the power saving mode is classified into a manual method or an automatic method.

For example, in the automatic method, when an emergency message to be described later is received, a power saving mode may be switched according to the contents of the received emergency message. In addition, the automatic method is a method of switching to the power saving mode according to the power saving mode switching conditions such as the arrival of a set time, a predetermined place, or the like when the remaining battery level is lower than a predetermined level. Accordingly, the controller 110 may check the power saving mode switching condition and automatically switch to the power saving mode when the condition is satisfied. On the contrary, in the case of the automatic mode, when the condition is not satisfied due to initiation of charging in the power saving mode or departure from the place, the automatic mode may be automatically switched to the normal mode.

According to various embodiments of the present disclosure, the emergency message that may be received by the electronic device 100 may apply any kind of emergency message. For example, when the user is in an emergency situation such as distress or kidnapping, the user may not be able to cope with the emergency situation directly. In such a case, it is necessary to switch to the emergency mode at the request of a designated user such as a family member. To this end, according to an embodiment of the present disclosure, there is a method of designating a user who can send an emergency message to the electronic device 100 of the user, and switching to the emergency mode by the designated user. When an emergency situation is received by the designated user through, for example, a Find My Mobile (FMM) server, the emergency message may be sent from the FMM server to the electronic device 100 of the user. The emergency message from the FMM server may be used to find a user who is in an emergency situation through the location inquiry of the user's electronic device 100.

In addition, according to various embodiments of the present disclosure, the emergency message may be a message provided from any service server that provides emergency information. For example, when an emergency disaster situation (eg, typhoon, tsunami, earthquake, etc.) occurs, a message provided by a cell broadcast message service (CBS) server or an earthquake and tsunami warning service (ETWS) server that provides emergency disaster information. It may be, but is not limited to such.

According to various embodiments of the present disclosure, the manual mode may be switched to the power saving mode through a setting change window for mode switching. In addition, it may be implemented to be switched through a long press of the power key of the keypad 166 or a button, a setting menu, etc. included in a status bar indicating a status of the electronic device 100.

As described above, according to an exemplary embodiment of the present disclosure, the driving time of the electronic device may be maximized by controlling power saving items such as data with the network, a display unit, and a function excluding a call related function.

In addition, according to various embodiments of the present disclosure, the power saving may be adjusted step by step, and accordingly, an operation limited by the power saving step may vary. For example, when the user triggers to enter the power saving mode or the power saving level can be adjusted through the setting menu. This power saving step may be composed of two or more steps, and the step-by-step operation may be determined as follows.

For example, the first power saving step may correspond to a basic power saving mode that is basically implemented in the electronic device. In the second power saving step, the screen brightness is limited and the screen is added in addition to the operation limited to the basic power saving mode. The operation of the black and white display can be determined.

In the third power saving step, an operation of limiting data transmitted and received in the background may be determined in addition to the operation limited in the second power saving step, which may also be referred to as an ultra power saving mode.

In the case of the fourth power saving step, an operation of limiting the resolution to 50% and an operation of limiting the touch area to 50% may be determined in addition to the operation limited in the third power saving step. In this case, when the resolution is reduced to 50%, the size of the screen area displayed on the touch screen 190 is reduced by half, and the remaining areas except the half screen area may be processed in black and white. For example, only a portion of the screen area, not the entire screen area that occupies the entire touch screen 190, may be displayed on the touch screen 190. A portion of the screen area may be disposed in the center of the touch screen 190, and the arrangement position may not be limited thereto. Accordingly, an area in which a user can touch may be limited to a portion of the screen area. In this case, only 50% of the touch area needs to be processed as much as the resolution, thereby reducing the current in the application processor. In the foregoing description, power saving steps including one to four steps have been described as an example, but the configuration of the operation limited to each step is not limited thereto.

For example, the application processor 320 may perform an operation for providing other functions except basic call related functions such as a camera function, video playback, and music file playback.

The application processor 320 may communicate with the communication processor 310 through a kernel data path. Accordingly, when the communication processor 310 receives basic call-related data such as a call or a message through the network 340, the application processor 320 may receive related data from the communication processor 310 through the kernel data path. have.

The application processor 320 may control the electronic device 100 to enter the standby mode when the booting of the operating system is completed and display the standby screen on the touch screen 190. If the lock function is set after booting, the lock screen may be displayed.

The network 340 may be configured regardless of communication modes such as wired and wireless, and may include a personal area network (PAN), a local area network (LAN), and a metropolitan area network (MAN). And a wide area network (WAN). In addition, the network 340 may be a well-known World Wide Web (WWW), or may use a wireless transmission technology used for short-range communication such as an infrared data association (IrDA) or Bluetooth. . In addition, the network 340 may include a cable broadcast communication network, a terrestrial broadcast communication network, a satellite broadcast communication network, etc. for receiving a broadcast signal from the power saving mode processing apparatus 300.

In the power saving mode operation according to various embodiments of the present disclosure, the communication processor 310 may minimize power consumption by blocking various communication-related functions (for example, functions related to the network 340). According to various embodiments of the present disclosure, the communication processor 310 may stop step by step in blocking a network 340 related function, that is, a communication connection. The communication method to be blocked may be determined in consideration of various methods such as blocking based on at least one of them. For example, when the communication processor 310 is connected to at least one of the communication methods such as Bluetooth and Wi-Fi, the communication processor 310 may sequentially block in consideration of at least one of a high power consumption method, a low use frequency method, and a recently used method. It may be.

The application processor 320 according to various embodiments of the present disclosure may minimize power consumption by blocking execution of other applications except essential applications in a power saving mode.

In the communication processor 310 and the application processor 320, at least one method may be selectively applied among various function limitations for reducing power consumption, which will be described later.

4 is a flowchart illustrating an operation of switching to a power saving mode of an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 4, the electronic device 100 is supplied with power to the communication processor 310 or the application processor 320 in a normal mode so that both the communication processor 310 and the application processor 320 are driven as in operation 400. do. In this state, the standby screen may be displayed, and the screen may be turned off after the set time elapses.

As described above, in a state where both the communication processor 310 and the application processor 320 are driven, a screen corresponding to a user input may be displayed by the application processor 320. Examples of such a screen include a standby screen, a main menu screen, an application execution screen, and the like.

According to various embodiments of the present disclosure, in this state, the electronic device 100 determines whether to switch to the power saving mode in operation 405. In the case of the manual method, the user can select a power saving mode through a mode setting menu. In the case of the automatic method, the power saving mode can be switched even if the set power saving mode switching condition is satisfied. If the switch to the power saving mode is selected, the electronic device 100 may limit some functions of at least one of the communication processor and the application processor in response to the power saving method in operation 410.

According to various embodiments of the present disclosure, at least one of the communication processor and the application processor may be blocked in response to the power saving scheme. For example, the driving of the application processor 320 is blocked so that only basic call related functions are performed, and only the communication processor 310 may be driven. In this case, peripheral devices such as the touch screen 190 and the keypad 166 may be operable for screen display and key input. In this case, a basic call related function such as a call or a message is performed by the communication processor 310, and a minimum application for performing the basic call related function is driven. As such, when only one processor is driven, power consumption is reduced to maximize battery life.

According to various embodiments of the present disclosure, when the switch to the power saving mode is selected in the normal mode in which both the communication processor 310 or the application processor 320 are driven, the electronic device 100 moves to the power saving mode in operation 415. You can change the setting. Subsequently, as the electronic device 100 switches to the power saving mode, the electronic device 100 may display a power saving mode screen in operation 420. In FIG. 4, the case in which the driving of one of the processors is blocked when the power saving mode is switched is described as an example. However, the communication processor 310 or the application processor 320 may be selectively applied by various methods of limiting functions for power saving. Some functions of may be implemented to be limited.

According to various embodiments of the present disclosure, a method of performing a power saving mode in an electronic device may include driving at least one processor; Detecting a command to switch to a power saving mode; And when the command for switching to the power saving mode is detected, the operation of the at least one processor may be limited to block the set functions other than the power saving call function in response to at least one of the set power saving methods.

According to various embodiments of the present disclosure, the at least one processor may include at least one of a communication processor and an application processor.

According to various embodiments of the present disclosure, the set power saving schemes may include a network restriction scheme for restricting network-based information transmission, a process limitation scheme for restricting the use of a background service in a screen off state, and other applications except for the required essential applications. It may include at least one of an application limiting method for limiting the use or a screen limiting method for limiting the screen display.

According to various embodiments of the present disclosure, the command to switch to the power saving mode may be any one of a mode change request or an emergency message received by a user.

According to various embodiments of the present disclosure, the emergency message may be received from a server in response to a request by a designated user.

According to various embodiments of the present disclosure, in the case of the network limiting method, the communication processor may fix a network function NAT to prolong the sleep period of the modem when the screen is off.

According to various embodiments of the present disclosure, in the case of the network restriction method, the path setting table may be deleted such that mobile data transmission and reception between the application processor and the communication processor is blocked when the screen is turned off.

According to various embodiments of the present disclosure, when the screen is turned off, the path setting table may be restored.

According to various embodiments of the present disclosure, in the case of the network restriction method, when the screen is off, the communication processor may block transmission of network information received from a network to the application processor.

According to various embodiments of the present disclosure, in the case of the process limiting method, a process in the application processor may be suspended when the screen is turned off, and a process that is pending when the screen is turned off may be performed when the screen is turned off. .

According to various embodiments of the present disclosure, when the command for switching to the power saving mode is detected, when at least one of the at least one communication scheme is connected, a power consumption scheme, a low frequency usage scheme, and a recently used scheme Based on at least one of the can be blocked sequentially.

According to various embodiments of the present disclosure, the set essential application may include at least one of a phone call application, a message application, and a web browser application.

According to various embodiments of the present disclosure, the screen limiting method may include at least one of an operation of switching the brightness of the screen to a predetermined value and displaying the screen in gray mode.

According to various embodiments of the present disclosure, when the command for switching to the power saving mode is detected, the screen brightness of the display unit is adjusted, the screen of the display unit is switched to the gray mode, the home screen of the display unit is switched to the home screen having the minimum function, Alternatively, a power saving screen configured by using at least one of inactivation of other applications except the set essential application may be displayed.

Hereinafter, various embodiments of the present disclosure will be divided into network power saving methods, process power saving methods, application limited power saving methods, and screen power saving methods according to power saving methods in order to limit various functions. At least one of the power saving schemes may be selectively applied.

According to an embodiment of the present disclosure, a function for gradually adjusting a power saving step according to at least one power saving method selected from among the power saving methods may be provided.

5 is a flowchart illustrating an operation in a power saving mode according to a network power saving method according to various embodiments of the present disclosure. Here, the network power saving method may mean a method of limiting network-based information transmission.

Referring to FIG. 5, in the case of the network power saving method 500, the electronic device 100 may change a network property in operation 505. For this purpose, the network preference can be changed to one attribute so as not to search for another network. For example, in order to prolong the sleep period of the modem when the screen is off, the communication processor 310 may fix the network function NAT, and thus, the network preference may be set to be fixed to the WCDMA network.

Referring to FIG. 6A according to various embodiments of the present disclosure, when accessing a WCDMA-based 3G network in a normal mode, the communication processor 310 may perform an operation such as an Internet connection in response to a user input. A search signal for LTE connection may be generated, and in order to provide a voice service for a call while being connected to the LTE network, the 3G network needs to be searched, thereby generating a signal for searching for 3G network. In this case, since LTE does not provide CS (Circuit Switching) based voice service, the basic call is the first priority in the power saving mode, and thus power consumption may be reduced if the LTE network is blocked from searching for the network.

Referring to FIG. 6 (b), according to various embodiments of the present disclosure, since the fixed mode is fixed to the 3G network, the communication processor 310 may maintain the 3G mode so as not to generate a search signal for searching for another network. do. Accordingly, since the search signal for another network is not generated, the communication processor 310 may reduce power consumption due to the search signal. After the network property is changed as described above, the electronic device 100 may deactivate the LTE icon displayed on the status bar, and display a power saving screen with limited LTE usage. The power saving screen may be turned off after a predetermined time elapses. However, since the weak electric field whose signal strength in the 3G network is below a certain strength after blocking the LTE network may consume a lot of battery, it may return to the LTE network for power saving.

According to various embodiments of the present disclosure, as described above, the communication processor 310 may generate a search signal for LTE connection or a signal for 3G network search for voice service when the Internet is connected in a normal mode. Transmission of the search signal is performed at a predetermined first period. However, in the power saving mode, the search may be performed in the second period instead of performing the search in the first period determined as in the normal mode. Here, the second period is longer than the first period, and its length may be determined according to the network environment. For example, when the electronic device 100 is located in an unserviceable area in a power saving mode, performing a network search at a predetermined first cycle may cause unnecessary power consumption. Therefore, the communication processor 310 according to an embodiment of the present disclosure Longer network scan intervals can reduce power consumption.

In addition, according to various embodiments of the present invention, when moving to a roaming region, periodic network searches are performed to find a network having a higher quality than a current network, for example, a network having a higher priority. In a power saving mode, the 310 may stop a network search for a better quality network even when a roaming situation occurs.

Accordingly, the electronic device 100 may determine whether the power save screen is in the off state in operation 510 according to various embodiments of the present disclosure. If the power saving screen is in the off state, in operation 515, the route table of the kernel region may be removed. If you remove the routing table, you can restrict the use of mobile data while the screen is off. The routing table may include routing information that enables the application processor 320 to select the network interface to send data to a given destination. Information included in such a routing table is well known and thus will not be described in detail.

Referring to FIG. 7A according to various embodiments of the present disclosure, in the normal mode, the application processor 320 may request data from the communication processor 310 through the kernel data path 700, and accordingly, the communication processor In operation 710, data exchange with the network 340, that is, data transmission and reception, is possible.

However, when the power saving screen is turned off in the power saving mode according to various embodiments of the present disclosure, the path setting table in the kernel region is deleted, and thus, between the application processor 320 and the communication processor 310 as shown in FIG. Kernel data path 700 may be blocked 730. That is, if the path setting table is deleted, the path may not be known in the application processor 320 which is the actual platform area, and thus data transfer to the communication processor 310 which functions as a modem or exists in the modem may be impossible. Accordingly, the application processor 320 may determine that the connection with the network 340 is lost because the socket cannot be created.

In addition, the communication processor 310 may receive data from the network 340, but data transmission to the network 340 is impossible (720), so that the communication processor 310 receives the data received from the network 340 It may not be transferred to the application processor 320. That is, the communication processor 310 may control the wake-up of the application processor 320. As described above, the waking up of the application processor 320 may be blocked except for the process allowed when the power saving screen is turned off.

At this time, the data transmitted from the network 340 to the communication processor 310 substantially does not exist. This is because the socket of the application processor 320 is disconnected from the network 340 and cannot generate a socket. For example, the push service of the messenger application may not be used in the power saving mode. When the screen is on, the messenger reception information may be notified.

According to various embodiments of the present disclosure, the application processor 320 considers the connection disconnected because it cannot transmit data to the communication processor 310, and notifies the corresponding application 330 of disconnection status (740). have. However, since the communication processor 310 and the network 340 are actually in a state of being connected, such a notification may actually correspond to a fake notify 740. If the mobile data is also requested or blocked every time the screen is turned on or off, the data connection or disconnection request will be sent to the network each time. Therefore, this request will not only slow down the network but also put a heavy load on the network itself. In addition, since the connection or disconnection operation is performed in the communication processor, power consumption of the electronic device 100 may occur a lot. However, according to various embodiments of the present disclosure, since the connection between the communication processor 310 and the network 340 is normally made regardless of screen on / off, the current consumption according to this repetitive operation is repeated even if the screen is on / off repeatedly. Since it does not occur, removing only the routing table can minimize power consumption.

In addition, according to various embodiments of the present disclosure, since data is not transmitted and received by the application processor 320 and data received by the communication processor 310 is not transmitted to the application processor 320, power is controlled as the wake-up is controlled. By minimizing consumption and suppressing data transmission and reception, power consumption can be minimized.

According to various embodiments of the present disclosure, the electronic device 100 may block reception of network information in operation 520. For example, the reception of information on network related functions such as Nitz (Network Identity and Time Zone) may be blocked. Therefore, the electronic device 100 does not receive the network time information from the network 340 when the screen is off, and does not need to update the network time information reception, thereby reducing power consumption. That is, since the communication processor 310 does not have to wake up to receive network information, power consumption may be minimized. In this case, according to various embodiments of the present disclosure, time information may be updated based on real time clock (RTC) information of the electronic device 100 itself. In addition to this network information, you can also block Proactive commands. The proactive command is a command transmitted from the SIM card of the electronic device 100 to the communication processor 310. The communication processor 310 sends a request based on the proactive command to a server in the network according to the proactive command. I can deliver it. Therefore, in the power saving mode according to an embodiment of the present invention, current consumption may be reduced by blocking proactive commands using such a network.

8A illustrates a case in which data transmission and reception is performed between the application processor 320 and the communication processor 310 when network information is received in the normal mode (810). In the normal mode, the application processor 320 may receive network information transmitted through the communication processor 310.

8B illustrates a case in which the received network information is not transmitted to the application processor 320 when the network information is received 820 in the power saving mode (830). According to various embodiments of the present disclosure, the network information is not transmitted to the application processor 320 in a state where the screen in the power saving mode is turned off. That is, even though the communication processor 310 receives the network information from the network 340, the communication processor 310 does not filter it and transmit it to the application processor 320. Accordingly, there is an effect of suppressing the wakeup of the application processor 320 in the communication processor 310. Here, the network information is information about a network-related function such as Nitz and may mean control information, not user information.

Subsequently, the electronic device 100 according to various embodiments of the present disclosure determines whether the switch to the normal mode is selected in operation 525, and when the switch to the normal mode is selected, the electronic device 100 switches to the normal mode in operation 530. In contrast, when the switch to the normal mode is not selected in operation 525, the electronic device 100 determines whether the power saving screen is off in operation 510. If the screen is turned on by the user, the electronic device 100 may restore the path setting table in operation 535.

In detail, the path setting table existing in the kernel area is deleted when the screen is off, but path information about the destination is not deleted in the link property, which is an area accessible from the application processor 320. Accordingly, when the screen is turned on, the application processor 320 restores the route setting table based on the route information on the destination.

Alternatively, when the screen is turned on, the electronic device 100 requests the data call list from the network 340. The electronic device 100 may update the routing table based on the response to the request.

The electronic device 100 according to various embodiments of the present disclosure releases the reception of network information in operation 540. Accordingly, the electronic device 100 performs an operation of updating the network time. Thereafter, the process returns to operation 510 and repeats the above-described process unless the switch to the normal mode is selected in operation 525.

As described above, according to various embodiments of the present disclosure, operations that are interrupted while the screen is turned off are processed at a time when the screen is turned on, thereby receiving periodic network information when the screen is turned off and data for operations executed in the background. By blocking the transmission and reception, there is an effect that can prevent unnecessary power consumption that occurred when the screen off.

In this case, the operation of the communication processor 310 and the application processor 320 in the power saving screen off state and the power saving screen on state will be described in detail with reference to FIG. 9.

FIG. 9A illustrates a case where data transmission and reception between the application processor 320 and the communication processor 310 through the kernel data path 700 is blocked 900 when the power saving screen is turned off. As shown in FIG. 9 (a), even when the path setting table is deleted, the internal path information is deleted, so that the communication processor 310 does not request to release the data connection to the network 340 (910). Accordingly, the connection between the communication processor 310 and the network 340 may be normally maintained. As such, a method of blocking data while the screen is turned off may not be a physically disconnected state by a blocking method using a routing table.

On the other hand, FIG. 9B illustrates a case in which a path setting table is restored while the power saving screen is turned on to transmit and receive data between the application processor 320 and the communication processor 310 through the kernel data path 700 (930). Doing. In this case, the application processor 320 may determine that the connection with the network 340 is reestablished through the restored path setting table, and may notify the application 330 of the connection status (940). However, since the communication processor 310 and the network 340 were not actually disconnected, this notification may actually correspond to a fake notify 940. In addition, since the connection is normally maintained between the communication processor 310 and the network 340, a separate data connection request is unnecessary (920). As described above, according to various embodiments of the present disclosure, since the path setting table is deleted or restored when the screen is turned off or on, the network 340 does not need to request a connection / cutting operation, and thus the speed is fast, and the communication processor 310 is admitted. In addition, since the connection / disconnection operation with the network 340 is not required, power consumption may be minimized. That is, only the cutting or connection is made only in the application processor 320, and since there is no additional operation required in the communication processor 310 and the network 340, power consumption may be improved.

10 is a flowchart illustrating an operation in a power saving mode according to a process power saving method according to various embodiments of the present disclosure. The processor power saving method is a method of restricting the use of the background service in the screen off state, thereby limiting the operation of the application processor 320.

Referring to FIG. 10, the electronic device 100 according to various embodiments of the present disclosure may determine whether the power save screen is in an off state in operation 1010 in the process power saving method 1000. Hereinafter, the process power saving operation may be performed by the application processor 320, but may also be performed by the communication processor 310 or the controller 110 with reference to the operation information of the application processor 320. In operation 1010, it may be determined whether the power save screen is in an off state.

According to various embodiments of the present disclosure, if the power saving screen is not in the off state in operation 1010, the electronic device 100 may stop at least one process not to be used in the power saving mode according to the process power saving method. For example, in an emergency situation where power saving is required, only the power saving call function is enabled, the display mode of the touch screen 190 is changed, the display method of the home menu is not available, or the specific application cannot be used. At least one process may be processed to be interrupted except for a process such as setting to use the service. As such, by stopping at least one process not to be used in the power saving mode, unnecessary application operation may be blocked.

If it is determined that the power saving screen is in the off state in operation 1010, the electronic device 100 according to various embodiments of the present disclosure may block a process in the application processor 320 other than the call in operation 1015. Accordingly, a list of processes to be processed when the screen is off, for example, an alarm process table, may be removed.

The blocking of a process according to various embodiments of the present disclosure refers to an operation of limiting a process. Examples of the limited process include starting a process by RTC (Real Time Communication) interrupt, starting an application process, and synchronizing. It may include limiting the operation. Among them, the RTC interrupt may refer to all interrupts registered in units of time, and may mean that all the tasks requested to the controller 110, that is, the CPU are blocked by the interrupt.

Accordingly, when the control unit 110 executes a program, the control unit 110 is notified and processed when an apparatus such as input / output hardware or an exception occurs and processing is required. In various embodiments of the present disclosure, such an interrupt may be used. The processing required by can be temporarily held at the time of screen off and then performed at the time of screen on. In addition, even when the third-party application requests the controller 110 to process the process, the request may be performed when the screen is turned off but the screen is not processed. Further, for example, other functions except for a signal received in the form of a control message such as a call or a message may be blocked. Accordingly, a push service may not be used in the screen off state, and push information may be notified when the screen is in the on state. In addition, the application processor 320 may be implemented such that all processes for synchronization are not executed. As described above, in the screen off state, all process processing except the system area and the network area can be held in the buffer queue.

According to various embodiments of the present disclosure, the controller 110 may store the buffer 110 in a buffer queue instead of performing the processing whenever an interrupt is required while the screen is turned off. That is, the alarm process table indicating the tasks that had to be processed while the actual screen was turned off while adding tasks requested for processing to the buffer may be deleted.

According to various embodiments of the present disclosure, it may be determined whether the switch to the normal mode is selected in operation 1020 while the power saving mode is maintained. If switching to the normal mode is selected, the operation can be switched to the normal mode in operation 1025. On the contrary, if the switch to the normal mode is not selected in operation 1020, the operation returns to operation 1010 to determine whether the power saving screen is turned off. If the power saving screen is turned off, the electronic device 100 processes the pending process in operation 1030, and then proceeds to operation 1020. This makes it possible to process all the processes that are pending in the buffer queue at once. In operation 1020, the process returns to operation 1010 and the above-described process is repeatedly performed unless switching to the normal mode is selected in operation 1020.

According to various embodiments of the present disclosure, in the power saving mode, registration of an alarm manager (3rd party application service) may be restricted. Therefore, it is possible to limit the use of the background service of the application.

FIG. 11 illustrates current consumption of the electronic device 100 according to a screen off / on state in a normal mode and a power saving mode, respectively.

Referring to FIG. 11A, in the normal mode, four alarms and a process start may be attempted 1110 in a state in which the screen is turned off 1100. In the normal mode, partial wake-up may occur in response to each of these attempts 1110. Each time such a wakeup occurs, current consumption may occur. Then, when the screen is turned on (1105), the application processor 320 is in a full wake-up (full wake-up) state, the current consumption is greatly generated by controlling the operation associated with the execution of the various applications 330 Can be.

On the other hand, when the screen is turned off in the power saving mode as shown in FIG. 11 (b), according to various embodiments of the present disclosure, the CPU of the electronic device 100 may maintain the sleep state without breaking. It may be. Therefore, when the screen is turned off while operating in the power saving mode, an alarm and an attempt to start a process are blocked 1115, so that it can be seen that partial wake-up does not occur. Accordingly, it can be seen that there is no current consumption due to this attempt while the screen is turned off. On the other hand, when the screen is turned on, all of the tasks that were pending, for example, alarms and processes, may be processed 1125 at a time.

As described above, in the power saving mode according to various embodiments of the present disclosure, a partial wake-up may not occur in the screen off state, thereby saving power. Specifically, when the partial wake-up occurs, it does not enter the sleep mode immediately after the work is completed, but takes time for stabilization in the application processor 320 or the communication processor 310, and thus enters the sleep mode after a few seconds. can do. Therefore, considering the time required, the current consumption due to partial suppression of wakeup can be greatly reduced. In addition, according to various embodiments of the present disclosure, even if the screen is turned on and all operations are processed at the same time, the current is consumed more than the normal mode because it is in the same full wake-up state as in the normal mode. no. In other words, processing all pending tasks will consume current just as much as in normal mode.

12 is a flowchart illustrating an operation in a power saving mode according to an application limited power saving scheme according to an embodiment of the present invention. Here, the application limited power saving method refers to a method of restricting the use of other applications except for the required essential application.

Referring to FIG. 12, in the case of the application limited power saving method 1200, after determining the required application set in operation 1205, the electronic device 100 may deactivate applications except for the required application set in operation 1210.

FIG. 13A illustrates an example of changing a home screen configuration according to a power saving mode setting in an electronic device according to an embodiment of the present disclosure. Referring to FIG. 13A, when a power saving mode is changed according to various embodiments of the present disclosure as described above, a power saving mode dedicated home screen 1310 in which other applications or functions are removed while leaving only minimal functions on the home screen 1300. ) Can be provided. This minimizes power consumption during sleep.

As shown in FIG. 13A, the home screen 1300 of the electronic device 100 may be converted into a home screen 1310 in which a minimum function is disposed, and the minimum function, that is, a required essential application (for example, a phone call application 1315) is changed. ), A contact application 1320, a message application 1325, a web browser application 1330, and the like. In this case, when the user selects a main menu switch key, a menu screen 1332 may be displayed on the touch screen 190, and applications except for the required essential application are displayed or hidden on the menu screen 1332. Processing 1335 may be performed.

According to various embodiments of the present disclosure, an application displayed on the home screen 1300 may be divided into a case in which transmission and reception of data through a network is required and a case in which the application is selected (or launched). . For example, since the web browser application 1330 is an application requiring data transmission and reception, such a web browser application 1330 may be allowed only when registered in the launcher. If the web browser application 1330 is not registered in the launcher, the web browser application 1330 may be displayed in an inactive state. In addition, in the case of the message application 1325, when a user wants to check the contents of an existing message, data transmission / reception with the network is not required, and thus, the message application 1325 may operate even when not connected to the network. That is, the message application 1325 on the power saving mode home screen 1310 can be executed, and the user can check the existing message contents, but the number / sending of new messages may be limited. However, data may be available when registered in the launcher. Accordingly, when the message application 1325 is registered in the launcher, messages may be received / sent even in a power saving mode.

13B is a diagram illustrating a screen of a home screen in an emergency mode in the electronic device 100 according to an embodiment of the present disclosure. As shown in FIG. 13B, when switching to the emergency mode, the home screen includes essential applications (eg, LED lights 1350, siren 1351, location transmission 1352, and telephone) set in response to emergency situations such as distress and earthquake. 1353, earthquake manual 1354, emergency call 1356, and the like. In this case, the '+' icon 1355 may represent a hidden application, or alternatively, may be used as a button for adding an application.

On the other hand, even if the deactivation of the remaining applications other than the essential application set as described above it may be possible to implement so that the user can manually activate a specific application from among the deactivated applications according to an embodiment of the present invention. FIG. 13C is a diagram illustrating a screen for describing a power saving mode setting method in an electronic device according to an embodiment of the present disclosure. FIG.

According to various embodiments of the present disclosure, when the power saving mode setting menu is selected by the user, the power saving mode setting screen 1360 may be displayed as shown in FIG. 13C. In the power saving mode setting screen 1360, the user may set whether to use functions to be restricted in the power saving mode. For example, when selecting the data blocking function 1365 for each application, the application list screen 1370 may be displayed. For each application on the application list screen 1370, at least one application to be allowed in the power saving mode may be selected through a check box.

As such, data for applications other than the application specified by the user or the basic application in the emergency / sleep mode may be blocked.

According to various embodiments of the present disclosure, in operation 1215, the electronic device 100 may display at least one of disabled applications displayed as 'Disabled' 1645 on the screen 1640 on which the application list is displayed, as shown in FIG. 13A. If the user requests the activation of the application, in operation 1220, it may be determined whether the requested application can be activated in the power saving mode. As a result of the determination, when the application that the user requests activation is an application that can be activated in the power saving mode, the corresponding application may be switched to the activated state in operation 1225.

On the contrary, if the application requested by the user is not an application that can be activated in the power saving mode, the corresponding application is kept in an inactive state. In this case, the deactivated state of the application may be processed to produce the same effect as that of deleting the corresponding application. Accordingly, for example, the application may be prevented from consuming power by operating in the background of the electronic device.

According to various embodiments of the present disclosure, whether to activate the power saving mode of each application may be determined in consideration of the power consumption of the corresponding application. For example, a power-intensive application such as a game may be implemented to not be activated by a user's request, and an application that requires a lot of use without a high power consumption such as a messenger may be deactivated by default. It can be implemented to switch to the active state according to the user's choice.

In addition, in consideration of the usability, up to N desired applications can be activated. For example, if up to three activations are enabled and the A, B, C, and D applications are disabled, if the user wants to use the A, B, or C applications, switch them to the active state. It is available. However, if the user wants to use the D application, the D application can be deactivated only after restricting the use of any one of A, B, and C applications. In this way, the maximum number of possible activation can be arbitrarily changed by the manufacturer.

In this state, when the switch to normal mode is input (or detected) in operation 1230, the electronic device 100 switches to the normal mode in operation 1235, but when the switch to normal mode is not input (or detected) 1210. Returning to the operation, the above-described process may be repeated.

14 is a flowchart illustrating an operation in a power saving mode according to a screen power saving method according to various embodiments of the present disclosure.

Referring to FIG. 14, if there is a command to switch to a power saving mode, the electronic device 100 may minimize screen brightness in operation 1400 in the screen power saving method according to various embodiments of the present disclosure. Here, minimizing the screen brightness means setting a predetermined brightness value that can be read. For example, when the maximum screen brightness is 100 and the black screen is 0, the screen brightness is about 10%. Can be set, and the minimum value of the screen brightness can be adjusted.

In operation 1405, the electronic device 100 may display the power saving screen 1510 in operation 1410 by switching the display screen 1500 of the electronic device to black and white in operation 1405. If the animation is being executed on the display unit 1500, the execution of the animation is stopped when switching to the power saving mode, and the power saving screen 1510 in the stopped state may be displayed. By stopping the execution of the animation, no additional operation of the application processor 320 is required, thereby reducing the current consumption. In this state, when the switch to normal mode is input (or detected) in operation 1415, the electronic device 100 switches to the normal mode in operation 1420, but the switch to the normal mode is not input (or detected). Returning to the operation, the above-described process may be repeated. In addition to reducing the screen brightness and the screen resolution, power consumption may be reduced.

On the other hand, as an example of the situation that needs to switch to the power saving mode, there may be an emergency disaster situation. For example, if it is possible to minimize the battery consumption of the electronic device in the event of an emergency disaster, it is possible to increase the time to contact the outside in a dangerous situation can significantly increase the probability of rescue and survival.

Hereinafter, a method for minimizing battery consumption of an electronic device when an emergency disaster occurs will be described as an example.

Also, the electronic device according to the present invention may be a flexible device or a flexible display device.

An example of such an electronic device is a portable device (eg, a mobile phone, a smart phone, etc.), and some of the configurations of the electronic device described below may be omitted or changed as necessary.

Hereinafter, a structure of a system and an apparatus according to various embodiments of the present disclosure will be described with reference to FIGS. 16 and 17.

16 is a diagram illustrating an emergency disaster message transmission system according to an embodiment of the present invention. Referring to FIG. 16, an emergency disaster message transmission system according to an embodiment of the present invention may include an emergency information providing server 1610, a communication network 1620, a user device 1630, and the like.

The emergency information providing server 1610 generates an emergency disaster message and transmits the generated emergency disaster message to each user device 1630 (eg, an electronic device). At this time, the emergency disaster message transmitted, as described above, type of disaster (eg, earthquake, tsunami, tsunami, etc.), information related to the disaster time, information related to the distance of the disaster area, information related to the degree of disaster (eg , Earthquake intensity, tsunami intensity, etc.).

In addition, the type of emergency disaster message may be generated as a message of a certain type defined in the mobile communication standard, transmitted by the mobile communication standard protocol, or may be transmitted in the form of a short message.

As such, the emergency disaster message transmitted from the emergency information providing server 1610 is transmitted to the user device 1630 through the communication network 1620. In this case, the user device 1630 may be the aforementioned various types of electronic devices.

The communication network 1620 may be configured in any communication mode such as wired and wireless, and may include a personal area network (PAN), a local area network (LAN), and a metropolitan area (MAN). Network, a wide area network (WAN), and the like. In addition, the communication network 1620 may be a well-known World Wide Web (WWW), and may use a wireless transmission technology used for short-range communication such as an infrared data association (IrDA) or Bluetooth. It may be. In addition, the communication network 1620 may include a cable broadcasting communication network, a terrestrial broadcasting communication network, a satellite broadcasting communication network, and the like for receiving a broadcast signal from the user device 1630.

The user device 1630 that receives the emergency disaster message from the emergency information providing server 1610 through the communication network 1620 analyzes the received emergency disaster message according to an embodiment of the present invention, and according to the analyzed content Change at least one setting of the device 1630. In the following description, the user device 1630 is described as an electronic device.

17 is a block diagram illustrating a detailed structure of an electronic device according to an embodiment of the present disclosure. Referring to FIG. 17, an electronic device 1700 according to an embodiment of the present disclosure may include a communication unit 1710, a display unit 1720, a controller 1730, and a storage unit 1740.

The communication unit 1710 receives an emergency disaster message from the emergency information providing server 1610 and provides it to the control unit 1730.

The controller 1730 may be configured to generate the received emergency disaster message as a pop-up window through the display unit 1720, and may not display the received emergency disaster message according to another embodiment of the present invention. The controller 1730 may include a message analyzer 1731, a mode switch processor 1720, and a setting change window generator 1735.

The message analyzer 1731 analyzes the contents of the emergency disaster message received through the communication unit 1710 and performs a function of determining whether there is an emergency. The message analyzing method may be a method of parsing a message and extracting at least one keyword included in the message.

In addition, for example, in case of an emergency disaster message, at least one of the type of disaster information, the information related to the disaster time, the information related to the distance of the disaster area, and the information related to the degree of disaster may be included. Analyze more effectively.

In a more specific example, an emergency disaster message might say, "An earthquake of magnitude 5 occurred in Suwon." If it includes such content, it is possible to extract information such as 'Suwon', 'jindo', '5', 'earthquake' through the message analysis of the message analysis unit (1731).

In addition, if there is a term such as earthquake, "earthquake" or "地震" in the message content as in the above message, the word "intensity" and "震度" has a high probability of being included in the message. The word N 'may be searched for and extracted, and the emergency mode may be determined based on the extracted N value.

As another example, an emergency disaster message `` a tsunami occurred 20km off Incheon. '' If it includes such content, such as 'incheon', 'offshore', '20km', 'tsunami' can be extracted through the message analysis of the message analysis unit (1731). In this case, if there are terms such as tsunami, tsunami, 津波, etc. in the message content, it is very likely that the distance to the tsunami point is included in the message. The emergency mode may be determined based on the extracted N value. On the other hand, the above-described example may be modified and implemented in any other method as an example of the present invention.

As described above, the message analyzer 1731 may analyze the received emergency disaster message to determine whether there is an emergency or an emergency step according to the type of disaster.

The mode switch processing unit 1732 may switch the mode of the electronic device to the warning mode or the emergency mode according to the emergency stage determined by the message analyzer 1731. Meanwhile, in an exemplary embodiment of the present invention, it may be set to switch to one mode (for example, an emergency mode) or may be set to two or more modes such as a warning mode and an emergency mode according to another embodiment of the present invention.

When setting to the two or more modes, the setting according to each mode may be different, and each of the plurality of modes may be changed step by step depending on the degree of urgency according to the message analysis.

Hereinafter, embodiments of the present invention will be described an example that can be changed step by step to two modes of warning mode and emergency mode, but the present invention is not limited thereto.

For example, when the degree of emergency is less than or equal to a preset criterion according to the message analysis, or the degree of disaster is not included in the message, the warning mode may be set through the warning mode switch 1732a. In addition, if the degree of emergency exceeds a predetermined criterion or satisfies a specific condition in the warning mode, the emergency mode switching unit 1732b may be set to switch to the emergency mode. Detailed embodiments thereof will be described later.

As described above, when the mode of the electronic device is changed through the mode switching processor 1732, the screen display setting of the display 1720 may be changed or various settings of the electronic device may be changed according to the corresponding setting mode.

For example, when the warning mode is switched, the warning mode switching unit 1732a may set and display the electronic device in a warning mode state in a flag form, and then may determine each situation to switch to the emergency mode. In addition, in the warning mode, it may be set to be able to switch to the emergency mode by a user's operation, and a usage restriction may be set for some applications. Specific examples of the warning mode will be described later.

Meanwhile, when switching to the emergency mode, the emergency mode switching unit 1732b may limit the remaining functions while leaving only the minimum functions necessary for the electronic device to minimize power consumed by the electronic device. For example, other functions may be disabled while leaving only functions related to calls, message reception, and the like. In addition, the screen displayed through the display unit 1720 may be switched to a power saving mode in which power is minimally consumed.

The setting change window generating unit 1735 generates a setting change window (eg, FIG. 25A) for setting a mode change function for the emergency situation, or generates a function setting change window (eg, FIG. 25B) for each mode switching. You can perform the function to create. According to an embodiment of the present disclosure, for example, when the electronic device is switched to the emergency mode and the applications installed in the electronic device are disabled, the user device is enabled for the specific application as shown in FIG. 28. You can create a configuration change window that can be switched.

The storage unit 1740 may store information such as data and application data necessary for providing a function according to embodiments of the present disclosure, and receive information on an emergency mode condition, current mode information, and reception set according to an embodiment of the present disclosure. Saved emergency disaster message information and the like.

On the other hand, the respective components of the device 1700 are shown separately in the drawings to show that they can be functionally and logically separated, and do not necessarily mean that they are physically separate components or implemented in separate code. .

In this specification, each functional unit may mean a functional and structural combination of hardware for performing the technical idea of the present invention and software for driving the hardware. For example, each functional unit may mean a logical unit of a predetermined code and a hardware resource for performing the predetermined code, and does not necessarily mean a physically connected code or a kind of hardware. It can be easily inferred by the average expert in the art.

Hereinafter, mode switching procedures according to various embodiments of the present disclosure will be described in detail with reference to FIGS. 18 to 22.

18 is a flowchart illustrating a mode switching procedure by an emergency disaster message according to an embodiment of the present invention. Referring to FIG. 18, when the electronic device receives an emergency disaster message 1802, the received emergency disaster message is analyzed 1804.

As a result of the analysis, when the condition for switching to the emergency mode is satisfied (1806-Y), the setting of the electronic device is changed to the emergency mode (1808). In this case, it may be implemented to automatically switch to the emergency mode according to the condition, or may be implemented to generate a pop-up window asking whether to switch to the emergency mode according to other embodiments described below, and to switch to the emergency mode according to the user's selection. .

On the other hand, when the analysis result, the condition to switch to the warning mode is satisfied (1810-Y), the setting of the electronic device to the warning mode (1812). In this case, the warning mode may be automatically switched according to the condition satisfaction, or a popup window may be generated to ask whether to switch to the warning mode according to other embodiments described below, and may be switched to the warning mode according to a user's selection. .

On the other hand, if neither the emergency mode condition nor the warning mode condition is satisfied, the current mode may be maintained (1814).

The emergency mode switching condition and the warning mode switching condition may be variously set. For example, when an emergency disaster message is received, it may be set to automatically convert to an alert mode by default, and may be set to be converted to an emergency mode when the degree of danger exceeds an established criterion by analyzing the content of the message. As another example, when an emergency disaster message is received, the content of the message may be analyzed and set to be converted into the warning mode or the emergency mode according to the degree of danger.

In addition, as described above, according to an embodiment of the present invention, when a corresponding mode switching condition is reached, it may be implemented to be automatically converted. Alternatively, a popup window may be generated to be converted to a corresponding mode according to a user's selection. In addition, as shown in another embodiment to be described later, if there is no user input for a predetermined time after generating the pop-up window, the present invention may be implemented to automatically convert to the corresponding mode.

On the other hand, in Figure 18 is shown that it is possible to change to two modes according to the analysis of the received emergency disaster message, as described above in accordance with other embodiments of the present invention to change to one mode (for example, warning mode), For example, it may be implemented to be changed to three or more modes according to an urgent degree. Accordingly, the electronic device may gradually apply a change to the function setting of the electronic device according to each mode.

19 is a flowchart illustrating an emergency mode switching procedure according to an embodiment of the present invention. Referring to FIG. 19, when it is determined 1902 to enter the warning mode by satisfying the switching condition of the warning mode as shown in FIG. 18, the state of the current electronic device is set to the warning mode by setting the warning mode status flag (1904). You can see that. In addition, according to the warning mode setting, the setting of at least one function preset among the functions of the electronic device may be changed. For example, some of the function settings to be applied in the emergency mode may be applied in advance, or a lower level of the function settings to be applied in the emergency mode may be applied (for example, it is possible to gradually adjust the brightness of the background screen of the touch screen). ). In addition, according to another embodiment, the warning mode state flag is set to indicate that the warning mode, and setting of other functions may not be changed.

In this way, when the switch to the warning mode, the function to manually switch to the emergency mode can be activated. Accordingly, the emergency mode switch menu is activated (1906), and the user may request (1908) the switch to the emergency mode through the emergency mode switch menu.

Therefore, in response to the user's emergency mode switch request, the electronic device may be changed to the emergency mode (1910). At this time, after entering the warning mode, if there is no switch to the emergency mode for a certain time, or if a specific event does not occur (for example, receiving another emergency disaster message), the warning mode is automatically released (1914), or the user The warning mode can be canceled according to the input of.

In addition, after entering the warning mode according to another embodiment of the present invention, if another emergency disaster message is received, if the emergency disaster message received more than a certain number of times, or if the warning mode entry condition is satisfied more than a certain number of times the emergency mode. It can also be implemented to change.

20 is a flowchart illustrating an emergency mode switching procedure according to another embodiment of the present invention. Referring to FIG. 20, when it is determined in 2002 that the warning mode switching condition is entered to enter the warning mode as shown in FIG. 18, the warning mode status flag is set in 2004 to set the status of the current electronic device to the warning mode. You can see that. In addition, according to the warning mode setting, the setting of at least one function preset among the functions of the electronic device may be changed. For example, some of the function settings to be applied in the emergency mode may be applied in advance, or a lower level of the function settings to be applied in the emergency mode may be applied (for example, it is possible to gradually adjust the brightness of the background screen of the touch screen). ). In addition, according to another embodiment, the warning mode state flag is set to indicate that the warning mode, and setting of other functions may not be changed.

As such, after switching to the warning mode, a case in which an emergency disaster message may not be additionally received according to various emergency disaster situations may occur. For example, after receiving an emergency disaster message, the communication network may be disconnected due to a sudden disaster situation, and thus an additional emergency disaster message may not be received. In this case, it is necessary to switch to the emergency mode but the mode cannot be changed because the message is not received. May occur. Therefore, according to another embodiment of the present invention, when the network disconnection situation occurs after entering the warning mode, it may be implemented to automatically switch to the emergency mode.

For example, after entering the warning mode, the electronic device checks the network state (2006), and when the network disconnection situation (2008) (for example, communication with the base station is not possible), the electronic device automatically switches to the emergency mode or the emergency mode. An emergency mode switchover window may be generated (2010) for the switchover.

If the user selects the switch to the emergency mode (2012) in the emergency mode switch window, the setting to the emergency mode may be changed (2014). As such, in addition to setting the emergency mode according to the analysis of the received emergency disaster message, when a specific condition is satisfied in the warning mode according to another embodiment of the present invention, the emergency mode may be additionally switched without receiving the emergency disaster message.

Thus, for example, when a base station is damaged or destroyed before receiving a message for switching to an emergency mode due to a sudden disaster, and a communication is not possible, it may be determined that the current situation is an emergency mode and automatically switched to an emergency mode. As a result, even if the base station is restored after a long time, the electronic device can be sustained for a long time, thereby enabling disaster relief more effectively.

21 is a flowchart illustrating an emergency mode switching procedure according to another embodiment of the present invention. Referring to FIG. 21, when the emergency mode switching condition is satisfied 2102 according to various embodiments of the present disclosure as described above, the system automatically switches to an emergency mode or generates an emergency mode switching window as illustrated in FIG. 25B. (2104) to switch manually.

Therefore, when the user selects (ok) 2106 the switch to the emergency mode in the generated emergency mode switch window, the setting of the electronic device may be changed to the emergency mode (2108). On the other hand, if the device 211 cancels the transition to the emergency mode, the current mode (eg, the warning mode or the normal mode) is maintained 2112.

On the other hand, the user may be configured to automatically switch to emergency mode 2116 when there is no user input for a preset time without selecting to switch to emergency mode or selecting rejection. For example, if the user cannot check the screen of the electronic device even though the condition for switching to the emergency mode is satisfied, the emergency situation is likely. Therefore, if the non-input status is maintained for a predetermined time, it may be implemented to automatically switch to the emergency mode as described above.

22 is a flowchart illustrating a setting procedure performed when switching to an emergency mode according to an embodiment of the present invention. Referring to FIG. 22, when the switch to the emergency mode is determined according to the embodiments of FIGS. 18 to 21, power consumption may be minimized by changing a setting of at least one of the functions of the electronic device.

For example, the lock screen may be released (2204) and the screen brightness of the electronic device display may be minimized (2206). In addition, as illustrated in FIG. 26, the screen of the electronic device display unit may be switched to a gray mode (2208).

In addition, as illustrated in FIG. 27, the home screen of the electronic device may be switched to the home screen having the minimum function to be used as the minimum function. In this case, the power consumption of the electronic device may be minimized by deactivating 2212 except for a required essential app (eg, a phone call app, a message receiving app, a web browser, etc.).

On the other hand, even if you deactivate the remaining applications other than the pre-set essential apps as described above, it is possible to implement so that the user can manually activate a specific application of the deactivated applications according to an embodiment of the present invention.

Accordingly, as shown in FIG. 28, when an activation request is requested 2214 among at least one of the disabled applications indicated as 'Disabled' in the application list, it is determined whether the requested application is an application that can be activated in an emergency mode. (2216) As a result of the determination, when the application that the user requests activation is an application that can be activated in the emergency mode, the corresponding application is switched to the activated state (2218). On the other hand, if the application that the user requests for activation is not an application that can be activated in the emergency mode, the corresponding application is kept in an inactive state. In this case, the deactivated state of the application may be processed to produce the same effect as that of deleting the corresponding application. Accordingly, for example, the application may be prevented from consuming power by operating in the background of the electronic device.

Meanwhile, whether to be activated in the emergency mode of each application may be determined in consideration of the power consumption of the corresponding application. For example, a power-intensive application such as a game may be implemented to not be activated by a user's request, and an application that requires a lot of use without a high power consumption such as a messenger may be deactivated by default. It can be implemented to switch to the active state according to the user's choice.

In addition, according to another exemplary embodiment of the present disclosure, power consumption may be minimized by not using a function related to various communication (eg, a network related function) in the electronic device.

For example, in the emergency mode, signal reception for a network related function such as Nitz (Network Identity and Time Zone) may be released. Therefore, power consumption can be reduced by not updating the network time information from the communication network.

Further, in the emergency mode, the use of the mobile data can be restricted by removing the mobile data logical path, and the related application can be notified that the connection is disconnected.

Thus, for example, the push service of the messenger application may be implemented to be disabled, and when the screen is on, the messenger reception information may be notified.

Also, in the emergency mode, registration of the alarm manager 3rd party application service may be restricted. Therefore, it is possible to limit the use of the background service of the application.

In addition, in the emergency mode, the CPU of the electronic device may be kept in a sleep state without breaking.
