Description

Controlling Current Consumption of Electronic Device

Various embodiments of the present disclosure relate to a technology for controlling current consumption in an electronic device.

An electronic device such as a smart phone or a tablet is an AP (application processor) for supporting an application or a function related thereto mounted on or mounted on the electronic device, and a communication processor (CP) (or a communication processor) for supporting a communication related function (or modem processor).

In general, the AP can control each function in connection with various functions supported by the electronic device (eg, Wi-Fi, GPS, Bluetooth, display, etc.), but for this, the AP consumes a relatively large amount of current. It must remain active. On the other hand, the CP relatively consumes a small amount of current compared to the AP.

If the electronic device is not used for a long time, the AP may enter an in-active or sleep state. For example, when the user of the electronic device sleeps or leaves the electronic device unattended for a long time, the electronic device may enter a sleep state while turning off the display and deactivating the operations of various sensors in order to reduce power consumption.

Meanwhile, in the case of an electronic device supporting cellular communication such as 3G/2G or LTE, even if the AP enters an inactive state to perform a discontinuous reception (DRX) operation, the CP is periodically activated (wake up) It is possible to obtain paging information.

The electronic device may include various settings for putting the AP into a sleep state in order to improve power consumption. For example, when no user input, application notification, or data communication occurs in the electronic device for 30 minutes, the electronic device may enter a low power mode while changing the AP to a sleep state.

When the electronic device receives a new message (eg, SMS, etc.) in the low power mode, the electronic device may activate the AP again, turn on the display, and output a notification about the message on the display. When the user is asleep or the electronic device is in the bag and the user cannot check this notification, the electronic device maintains the display ON state for a certain period of time and keeps the AP in the active state. Such an operation consumes considerable power, but as a result, no information is provided to the user.

Various embodiments disclosed in this document provide information about various functions or modules of an electronic device while maintaining a sleep state of the AP by using a CP that has relatively low power consumption but has processing power like the AP. An object of the present invention is to provide a method for minimizing unnecessary or meaningless power consumption by performing control.

An electronic device according to various embodiments of the present disclosure may include an application processor (AP) that controls a plurality of functions, a communication processor (CP) connected to the AP, and a sensor module or communication module connected to the CP. When the AP enters a sleep state, the CP controls at least some of the plurality of functions based on information collected from the sensor module or the communication module according to a discontinuous reception (DRX) operation period. can

In addition, the electronic device according to an embodiment includes an AP, a CP that is connected to the AP and searches for available radio resources according to a DRX operation period, and the CP includes the DRX operation period when a specified condition is satisfied. It is possible to omit the search for the available radio resource in at least some sections.

According to various embodiments of the present disclosure, by utilizing the periodic repetitive operation for acknowledging DRX paging reception of the CP, the CP does not activate the AP for a specific operation even in a situation in which the AP enters the sleep state, but through the CP’s own computational capability. There is an effect of reducing power consumption by performing the corresponding operation. In addition, for DRX, information collection, status determination, function control, etc. are performed at the timing when the CP is active to deactivate operations determined to be unnecessary for the current state of the electronic device, thereby optimizing power consumption of the electronic device.

1 conceptually illustrates an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 1 , an electronic device may include an AP 100, a CP 200, and components 300 corresponding to various functions. In some embodiments, the AP 100 and the CP 200 may be included in one integrated chip, such as a system on chip (SoC). For example, the SoC may include a CPU, a GPU, and a CP, where the CPU and the GPU may correspond to the AP 100 . In various embodiments, the AP 100 may correspond to a device in charge of controlling overall functions of the electronic device, and the CP 200 may correspond to a device in charge of communication of the electronic device.

The electronic device may include various components 300 for performing various functions. For example, the electronic device may include a sensor module 310 , a user input unit 320 , and a communication module 330 . Although FIG. 1 exemplarily shows a configuration for describing an embodiment disclosed in this document, some components are omitted or non-illustrated components such as a display, a microphone, and a speaker are added to the electronic device according to the embodiment. may be included.

The sensor module 310 may include, for example, an illuminance sensor, a proximity sensor, an acceleration sensor, and a gyro sensor. The user input unit 320 may include at least one of a touch screen panel of the electronic device, a physical keyboard or physical button, an electronic pen (eg, a stylus) or a panel for detecting the input, and a voice recognition module (eg, a microphone) for voice input. may include

The communication module 330 may include a cellular module for supporting cellular communication such as 3G or LTE. In addition, the communication module 330 may include a module for supporting Wi-Fi, Bluetooth (BT), Near Field Communication (NFC), and Global Positioning System (GPS). Also, although not shown, the communication module 330 may include a module for wired connection (eg, LAN) or USB communication, and a module for Wi-Fi Direct or Bluetooth Low Energy (BLE).

In various embodiments, some of the components for performing communication of the electronic device may be located inside the CP 200 . For example, a signal processing module (eg, RFIC) for cellular communication and GPS may be located inside the CP 200 . That is, an antenna and a front-end module (FEM) for each communication are located outside the CP 200, but some of the modules for signal processing may be located inside the CP 200.

In terms of the software architecture of the existing smartphone, the operating system (OS) such as Android, iOS, Linux, or Windows is all connected to the AP (eg AP 100). The AP is directly connected to CP, Wi-Fi, GPS, Bluetooth, display (eg, LCD, LED, etc.) and various sensors to control each function and perform calculations for data processing. For such an operation of the AP, the AP must maintain an active state, which may consume a lot of current. However, in various embodiments disclosed in this document, when the AP 100 enters the sleep state, the CP 200 acquires control authority for at least some of various functions that can be controlled by the AP 100, so that a specific function or operation is performed. Power consumption can be minimized by performing the execution instead of waking up the AP 100.

As used in this document, the expression of a control right for a specific function and a control right for a specific function block may be understood as follows. For example, when the target of control is one specific entity or component, the control right and the block control right may have the same meaning. For example, the GPS control authority and the GPS block control authority may have the same meaning. As another example, when the target of control for a specific operation is a bundle (group) of several objects/elements, the block control right may be used as an expression meaning the control right for the specific operation. For example, when the CP 200 collects information necessary to determine the state of the electronic device or whether the user uses the electronic device, specific sensors or various objects/elements that can obtain location information (eg, GPS, Wi- Fi module, etc.) may be expressed as a corresponding block. The expression “control right” described in this document may be appropriately replaced with “block control right” according to the embodiment or context.

Referring back to FIG. 1 , the AP 100 may be functionally connected to the CP 200 . For example, the AP 100 may grant a control right for a specific function to the CP 200 through a control manager 210 of the CP 200 . For example, the CP 200 may receive control authority for the sensor module 310 , the user input unit 320 , and the communication module 330 functionally connected to the CP 200 from the AP 100 .

When an electronic device is used by a user, such as surfing the Internet, watching a video, or playing a game (ie, when the AP 100 is in an active state), the AP 100 may be in charge of controlling ON/OFF of corresponding blocks or an operation cycle. (In the example of FIG. 1, the AP 100 is functionally connected to the CP 200 and the connection relationship with other components 300 is not shown, but the AP 100 can directly control any component of the electronic device when it is in an active state. However, when the user is not using the electronic device, or under certain conditions in which the electronic device may enter a low power mode (eg, playing music files stored in the electronic device, etc.), The AP 100 may provide a message indicating that the control authority for the corresponding block is transferred to the CP 200. In this case, the AP 100 may transmit information indicating that the AP 100 enters an inactive state or information on the specific condition to the CP 200 (eg, the control manager 210 ) together with the message. By operating in this way, it is possible to solve the problem of conflicting control rights between processors that may occur in connection with transferring control rights between the AP 100 and the CP 200 .

In the above-described embodiment, the AP 100 (or the electronic device) is in a specific state, for example, a sleep state, an audio playback state (eg, a state in which only an mp3 file is played while the display is OFF and a user input is not provided), or When entering a low power state defined by a user or a manufacturer, the AP 100 may transmit a control message for transferring control authority to the CP 200 . However, in various embodiments, it is possible to move the control authority according to the request of the CP 200. For example, when a specified condition is satisfied, the CP 200 transmits a control right request message to the AP 100, and the AP 100 determines the control right transfer condition according to the message to accept the request or reject the request. Messages can be forwarded to CP 200. If the AP 100 accepts the request of the CP 200, the AP 100 may enter the sleep state.

In various embodiments, the CP 200 may perform various operations on behalf of the AP 100 when the control authority is transferred from the AP 100 through the control manager 210 . In addition, the CP 200 may send a message for switching the AP 100 from an inactive state to an active state based on the collected information. Hereinafter, in addition to the control manager 210, the operation of the CP 200 through the state recognition unit 220, the position estimation unit 230, the network processing unit 240, the state determination unit 250, the operation execution unit 260, the scheduler 270, and the CP 200's own memory 280 will be described. do. At least some of the various sub-configurations constituting the CP 200 may be configured as hardware. In addition, an operation performed by each sub-component may be understood as an operation performed by the CP 200 . In other words, the configurations of the CP 200 defined in this document are for convenience of description, and it is sufficient that the operation by each configuration can be performed by the CP 200, and the configuration or implementation method of the CP 200 as the name of the configuration This is not limited. In addition, the connection relationship indicated by the arrow in FIG. 1 is a representative connection relationship, and one component does not limit the other components that can communicate. For example, other sub-components of the CP 200 other than the network processing unit 240 may access the memory 280 .

In various embodiments, the state recognition unit 220 may collect various information from the sensor module 310, the user input unit 320, the communication module 330, and the like. For example, the state recognizer 220 may obtain information about the brightness of a location where the electronic device is located from the illuminance sensor, information about the movement of the electronic device or information about the direction the display faces from the acceleration sensor, and the like. In addition, the state recognizer 220 may also acquire information on whether the electronic device is currently being used by recognizing a user's touch input or checking an input for a physical button. In addition, the state recognition unit 220 receives information from the communication module 330 on whether the current electronic device (eg, a smartphone) is connected or paired with another electronic device (eg, a tablet, smart watch, smart glasses, etc.). can be obtained The state recognition unit 220 may provide various types of acquired information to the state determination unit 250 .

The location estimator 230 may obtain information on the current location of the electronic device from the communication module 330 . For example, the location estimator 230 may obtain current geographic location information of the electronic device from GPS coordinate information obtained from the GPS module. In addition, the location estimator 230 may obtain location information based on base station information obtained from the communication module 330, Wi-Fi access point (AP) information, or the like, or may correct location information obtained through GPS. The location estimator 230 may provide the acquired various information to the state determiner 250 .

The network processing unit 240 may collect information related to transmission and reception of data packets from components of the communication module 330, such as cellular, Wi-Fi, Bluetooth, NFC, etc., and perform a filtering operation to analyze and classify specific data packets. there is. For example, in a situation in which it is determined that the user is not using the electronic device for a predetermined time, the network processing unit 240 determines that the packet to be transmitted is a keep-alive message for maintaining the TCP session for a predetermined time. It may not transmit packets during a period (eg, disconnect data). Alternatively, in the above situation, the network processing unit 240 analyzes the received data packet, and a chat application message (eg, KakaoTalk, Line, Facebook Messenger, etc.) or SNS that should immediately notify the user of the received data packet. In the case of a (social networking service) message, a notification may be provided using a display, vibration, or sound. In this case, the CP 200 may directly provide a notification for the corresponding message using the control authority (eg, display or notification control authority) granted from the AP 100 without waking the AP 100 . Meanwhile, in some embodiments, when the received data packet does not need to immediately provide a notification to the user, the network processing unit 240 stores the data in the memory 280 and detects the use of the electronic device (eg, the user input unit 320 ). It is possible to provide a notification about the corresponding data at the time of unlocking, touch input, etc.). Also, in another embodiment, when the network processing unit 240 determines that the received data packet is unnecessary, the network processing unit 240 may delete the corresponding data. Also, the network processing unit 240 may provide status information related to data transmission/reception through the communication module 330 to the status determination unit 250 .

The state determination unit 250 uses the information collected from the state recognition unit 220, the information about the location and movement of the user (electronic device) collected from the position estimation unit 230, and the information collected from the network processing unit 240, You can check the status or the user's usage pattern. In various embodiments, the state determination unit 250 uses the information processing capability of the CP 200 to determine the user's location (eg, work or home) and mobility (eg, during jogging, in a running car) based on machine learning technology. ), the state of the electronic device (eg, in a pocket or bag, lying face down on a desk), and the like. The state determination unit 250 may provide the determination result of the state of the electronic device or the user's condition to the operation performing unit 260 .

The operation performing unit 260 determines whether to perform ON/OFF of a specific block, function, hardware ON/OFF, or operation cycle control based on the information provided from the state determination unit 250, and adjusts the data connection cycle accordingly , screen control (eg, turning off the display in a pocket/bag), or using other internet-connected devices, etc. to perform specific block control actions. For example, the operation performing unit 260 may maintain only some sensors among the acceleration sensor, the gyro sensor, the illuminance sensor, and the grip sensor in an activated state according to the determination result. In addition, the operation performing unit 260 may turn off the screen or control a button or a voice input (eg, turn off a microphone in an always-on state). Also, the operation performing unit 260 may deactivate a specific communication module (eg, at least one of Wi-Fi, Bluetooth, or NFC among the communication modules 330). The operation performing unit 260 may optimize power consumption by appropriately turning on/off various functions/modules using the control authority possessed by the CP 200 based on a series of status/situation determination results.

The scheduler 270 may effectively control the timing of a process in which several blocks collect and process information. For example, the scheduler 270 may determine which information to collect and process for each period by using the fact that the CP 200 periodically operates for DRX operation in the sleep state of the AP 100 . The type of information collected and processed according to the cycle may be variously determined according to the state of the electronic device, the user's usage pattern, or a change in conditions for the control operation of the CP 200 . However, in some embodiments, when a specific interrupt occurs or a specific condition is met, the scheduler 270 may exceptionally set operation control by the CP 200 even at a time other than the DRX operation (eg, paging) period. . Hereinafter, the embodiments will be described with a focus on the DRX operation period, but the above-described exceptional situation may be understood as a point in time when operation control by the CP can be performed.

2 illustrates an example of scheduling according to an operation period of a CP 200 according to various embodiments.

In the example of FIG. 2 , the AP 100 may be in an inactive state. Even if the AP 100 is in an inactive state, the CP 200 is periodically activated due to an LTE DRX operation to check whether paging is received. In the illustrated example, an operation performed during five cycles corresponding to T1 to T5 is exemplified based on the time when the CP is woken up by the DRX operation.

When the AP 100 enters the inactive state, the CP 200 is activated for paging in T1, and may transmit a data collection request message for the current state of the electronic device to the sensor 310 and the communication module 330 during the activation time. This message may be transmitted to each component through the state recognizing unit 220 and the location estimating unit 230 or the network processing unit 240 . This data collection request message may include a command to cause a specific module to perform a desired operation. For example, the data collection request message may include a command for causing the sensor 310 to collect data with respect to a specific factor or for causing the communication module 330 to collect current location information of the electronic device.

After sending the data collection request message, the CP 200 may wait until the time for the next DRX, that is, T2. At T2, the CP 200 can collect data from each component. In various embodiments, the CP 200 performs data collection at T2 for a component capable of immediate data collection, and collects data at the next DRX cycle, ie, T3, for a component that takes a certain time to collect data, such as location information. can be performed. The example of FIG. 2 is for convenience of explanation, and the CP 200 may perform data collection in periods such as T4 and T5 under the control of the scheduler 270 . (In this case, collection data processing may be scheduled after T6 (not shown).)

In various embodiments, the operation of the CP 200 controlled by the scheduler 270 may be understood as follows. When the electronic device enters a power saving mode operated based on the CP 200, the CP 200 may request data collection for determining the state of the electronic device from each component in the first DRX cycle. The CP 200 may collect data requested in the first DRX cycle in the second DRX cycle. The CP 200 may determine the state of the electronic device based on data collected in the third DRX cycle. In the fourth DRX cycle, the CP 200 performs a subsequent operation based on the determination, for example, turning on or off a specific function block using the control authority obtained from the AP 100, or activating the AP 100 and returning the control authority. can be transmitted.

In the above description, each DRX cycle may be understood to mean a precedence relationship. For example, the CP 200 may complete data collection by using the activation period of the CP for DRX operation several times. That is, in the example of FIG. 2 , it may be understood that T2 and T3 correspond to the second DRX cycle.

Also, the precedence relation may be understood as a precedence relation with respect to a specific function or specific information. For example, the CP 200 may make a request for GPS information in a first period, collect GPS information in a second period, and determine the collected information in a third period. At the same time, the CP 200 may request other functions or other information, for example, acceleration sensor information in the second period. That is, in the second period, data collection (GPS) and data request (acceleration) may be performed together.

Referring back to FIG. 2 , when the collection of all data or essential data requested in T1 is completed, the CP 200 may process the collected data in the next DRX cycle. For example, the CP 200 may determine the current state of the electronic device or the user's situation, and determine whether to maintain the inactive state of the AP 100 . The CP 200 may perform machine-learning by utilizing the processing power of the CP 200 to determine the state of the electronic device. In this regard, it will be described in detail with reference to FIG. 3 . If it is determined that the AP 100 needs to be activated, the CP 200 may transmit a control message (eg, wake-up message) for activating the AP 100 to the AP 100 in a next period (eg, T5). When the AP 100 receives the control message, the AP 100 may enter the activated state immediately or after a predetermined time.

In FIG. 2 , graphs for AP 100 and CP 200 may be understood as a high indicating an active state and a low indicating an inactive state. However, the graphs for the sensor 310 and the communication module 330 do not mean that the activation/deactivation state is maintained as a fixed state, and it is merely illustrated for the purpose of explaining the data collection request/data collection. In various embodiments, some modules (eg, an acceleration sensor) of the sensor modules 310 may enter an inactive state while maintaining an active state under the control of the CP 200 . In addition, in FIG. 2 , the CP 200 controls the sensor module 310 and the communication module 330 and collects data related thereto, but controls other components (eg, display, voice input module, etc.) not shown and transmits data. Collecting is also possible.

For the periodic operation of the CP 200, the scheduler 270 may efficiently control the timing of various operations for collecting and processing information. In addition, the scheduler 270 may determine which information is to be collected and processed at which period, etc. according to a state of the electronic device, a user's usage pattern, or a change in conditions for controlling the CP 200 . In various embodiments disclosed in this document, the control of the sensor, Wi-Fi, display, data connection, etc. performed by the operation performing unit 260 operates according to the periodic characteristics set by the scheduler 270, and the activation request of the AP 100 is performed. It can also operate according to a periodic characteristic.

3 illustrates an operation of a CP for determining a state of an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 3 , the state determination unit 250 of the CP 200 may include a machine-learning operation unit 251 and a terminal state/user condition determination unit 253 . The state determining unit 250 collects information related to a sensor or user input from the state recognition unit 220, collects GPS or cellular network-related position information from the position estimator 230, and collects information related to transmission and reception of data packets from the network processing unit 240 can be provided as

The machine-learning operation unit 251 may classify various user situations or electronic device states by using a machine-learning technique based on the processing capability of the CP 200 itself. In addition, the machine-learning operation unit 251 may build a database in its own memory 280 of the CP 200 by accumulating the learned data. When an input requesting an operation different from the state of the electronic device or the user's situation determined based on the learned result occurs, the machine-learning operation unit 251 may use the input as feedback to update the database.

The terminal state/user situation determining unit 253 is configured to determine the current state of the electronic device or the current user's situation based on the information collected from the state recognition unit 220, the position estimation unit 230, and the network processing unit 240 and the analysis of the machine-learning operation unit 251. judgment can be made. Furthermore, the terminal state/user situation determining unit 253 may predict an operation expected by the user based on the determined state or situation. For example, whether the current location of the user (electronic device) is at work or at home, whether the current terminal is stationary, jogging, or in a car, whether the terminal is in a pocket or bag or lying on a desk, whether the current user is exercising or sleeping You can determine whether you are in the middle of a meeting, in a meeting, or commuting to and from work.

For example, when the location estimator 230 provides access point (AP) information of Wi-Fi corresponding to the user's house or company, the state determiner 250 may determine that the electronic device is in the home or company. . The state determiner 250 may determine whether the electronic device is stopped from the value of the inertial sensor or the acceleration sensor provided by the state recognizer 220 . According to various embodiments of the present disclosure, when the electronic device is moving at a speed corresponding to the moving speed of the vehicle in the time period learned as the user's commuting time by the machine-learning operation unit 251, it is determined that the user is in the vehicle (or commuting to and from work).

In various embodiments, when it is determined that the current electronic device is in a dark place based on information of a proximity sensor or an illuminance sensor provided by the state recognizer 220, the state determiner 250 may determine that the current terminal is in a pocket or bag. When the current time is learned as the user's sleep time, and information obtained from components of the electronic device indicates a specific state (eg, illuminance sensor - darkness, inertial sensor - no movement, power management) Module - battery charging, etc.) It can be determined that the user is in a sleep state. In addition, various states of the electronic device or user that can be determined by the state determiner 250 may exist, and are not limited to the above-described examples.

In various embodiments, the state determiner 250 may predict an operation desired by the user of the electronic device. For example, the user's state may be a state in which it is meaningless to provide a notification to the user, such as while sleeping, in a meeting, or exercising, or in which no notification sound or vibration is generated. In addition, when the state of the electronic device is in a pocket or bag, the user may not be able to see it even if the screen notification is provided by turning on the display, and the user may not want unnecessary power consumption. In this case, in order to minimize power consumption, the state determination unit 250 may determine that the screen notification is omitted and that the notification through sound or vibration is desired. In addition, when the user is at a specific location, for example, when arriving at home, the state determination unit 250 may predict that a BT connection between the note PC or tablet at home and the user terminal is desired. In various embodiments, the determination content and the user's desired action may be directly input by the user or may be automatically generated through a machine-learning technique. The operation patterns input or generated in this way may be stored and managed in the memory 280 inside the CP 200.

When the operation performing unit 260 obtains a determination result (eg, information on a terminal state or user condition) from the state determination unit 250, ON/OFF of a specific block (function) or control of an operation period, etc. based on the result can be performed.

In various embodiments, the operation performing unit 260 may include (or perform a mode management function) a mode management unit (not shown). The automatic operation mode 263 and user-customized mode 265 registered by the mode processing unit 261 and the mode processing unit 261 may be managed by the mode management unit. The mode processing unit 261 may classify and register various modes input by a user or generated by machine-learning into an automatic operation mode 263 or a user-customized mode 265 . Also, the mode processing unit 261 may delete the registered mode.

The automatic operation mode 263 may include automatic modes generated through a machine-learning technique, such as a display OFF mode, a sleep mode, an indoor mode, an outdoor mode, and the like. The user-customized mode 265 may correspond to a user mode directly generated by a user, suitable for repetitive tasks required by the user, such as a meeting, exercise, entertainment, and rest. For example, the user can directly set the monitoring, notification method, sensor, call/SMS reception, operation by application, and lock screen through the user input unit 320 . For example, the user may set a rest mode. As an exemplary rest mode, push notification OFF, call reception rejection, and SMS reception permission status of all applications may be set. In this case, when the electronic device enters the rest mode, the CP 200 stores all push notifications received from the network processing unit 240 in the memory 280 without providing a notification, does not provide a notification for a call, and only informs the user of the received SMS. can Also, the operation may be performed at an appropriate DRX cycle as described above.

According to various embodiments, as the user-customized mode 265 and the automatic operation mode 263 coexist, a situation in which several modes must be simultaneously operated in a specific situation may occur. For example, an automatic operation mode for a sleep state and a user-customized mode set by a user for a sleep state coexist and may conflict with each other. In this case, the above-described mode management unit may preferentially operate any one mode, or display a message for user confirmation with respect to a conflicting portion among both modes. In various embodiments, the mode manager causes the electronic device to operate based on an arbitrary mode, and when the sleep state of the AP 100 is released, the mode manager reports (displays) which mode of operation among various operable modes to the user and provides feedback thereto. can receive The feedback may be stored in the memory 280 and used to update data.

4 illustrates an example of CP-based low-power mode operation and low-power mode release according to various embodiments of the present disclosure.

Referring to FIG. 4 , when the AP 100 enters the sleep state, in operation 410, the AP 100 may transfer the block control authority to the control manager 210 of the CP 200 . When the CP 200 accepts the block control right, the electronic device may enter the CP-based low power mode.

In various embodiments, operation 410 may be performed immediately after the AP 100 enters the sleep state, but may also be performed after a predetermined condition is satisfied or a specified time elapses after the AP 100 enters the sleep state.

In operation 420, the electronic device may enter the CP-based low power mode proposed in this document. In this mode, the CP 200 may control some functions that are granted control authority from the AP 100 in operation 410, among a plurality of functions that the AP 100 can control. For example, when the CP 200 is granted screen control authority from the AP 100, it can control the display without waking the AP 100 so that a necessary message or notification is displayed.

When the electronic device enters the CP-based low power mode in operation 420, subsequent operations may operate according to the DRX cycle. For example, in operation 430, the CP 200 may collect information from components 330 such as the sensor module 310 or the communication module 330 to determine the state of the electronic device or the state of the user of the electronic device. In this case, the information collection/processing request from the scheduler 270 to the status recognition unit 220 may be processed in the first DRX cycle. The acquisition of information collected from the acceleration/illuminance/proximity sensor and the information collection/processing request to the network processing unit 240 may be processed in the second DRX cycle. Data transmission/reception information from the network processing unit 240 may be processed in the third DRX cycle. Such scheduling is exemplary, and it is sufficient if the operation performed by the CP 200 is performed while the CP 200 is operating for the DRX operation.

In the example shown in FIG. 4 , the scheduler 270 requests information from the state recognizer 220, the location estimator 230, and the network processor 240, respectively, and the corresponding information is collected by the state determiner 250, respectively. However, in various embodiments, it may be understood that each information collection request is transmitted to a corresponding external module/component. For example, when information collection is requested from the scheduler 270 to the state recognizer 220, when the corresponding information is information about acceleration of the electronic device, the state recognizer 220 may be understood to request information from the acceleration sensor. From the point of view of the CP 200, it can be understood that the CP 200 requests acceleration information of the current electronic device from the acceleration sensor at a specific DRX operation time, and then brings the requested information at an arbitrary DRX operation time. In a similar manner, the information request to the network processing unit 240 may be provided to the specific communication module 330 . It may be understood that the information request to the location estimator 230 is transmitted to a cellular module or GPS.

In operation 440, the state determiner 250 may determine the current state of the electronic device or the user's usage pattern based on information collected from various components. For example, the state determination unit 250 may determine that the display of the current electronic device is placed facing the desk surface or that the current electronic device is placed in a pocket or bag.

In operation 450 , the state determiner 250 may transmit the determination result in operation 440 to the operation performer 260 . In operation 460, the operation performing unit 260 may determine whether a condition (mode) corresponding to the received determination result exists. For example, if it is determined in operation 470 that the determination result corresponds to the display OFF mode, the operation performing unit may request the display (eg, the user input unit 320 ) to maintain the display in the OFF state. As another example, when the determination result indicates that the user is in the sleeping state, the operation of the remaining sensors except for a specific sensor may be changed to OFF, or all Wi-Fi, Bluetooth, NFC modules, etc. except for cellular communication, may be changed to an inactive state. .

In various embodiments, operations 430 to 470 may be continuously and repeatedly performed to optimize current consumption.

In operation 460, when there is no condition (mode) corresponding to the determination result (or when it is determined that the AP 100 needs to be activated), in operation 480, the operation performing unit 260 may request the control manager 210 to change the mode. For example, when a button input by the user is sensed or when it is detected that the display from the desk surface (downward) is changed to face upward, it may be determined that the AP 100 needs to be activated. When the control manager 210 receives the mode change request, in operation 490 , the control manager 210 may return the control right to the AP 100 and transmit an AP activation request message. Upon receiving the request in operation 490, the AP 100 may release the sleep state and enter the normal mode.

5 illustrates another example of CP-based low-power mode operation and low-power mode release according to various embodiments of the present disclosure. In the description related to FIG. 5 , descriptions of contents overlapping, corresponding to, or similar to those of FIG. 4 or FIGS. 1 to 3 may be omitted.

5 , the electronic device may enter a CP-based low power mode. The low power mode is an exemplary expression for convenience of description, and the embodiment for power saving proposed in this document may be used in various expressions such as a CP-based power saving mode, a power optimization mode, and the like. Entering the CP-based low power mode of the electronic device may correspond to operation 420 described above with reference to FIG. 4 .

In operation 510, the CP 200 may acquire various types of sensor information, transmission/reception data, or location information according to an appropriate DRX operation period according to the scheduling of the scheduler 270 . This process may correspond to operation 430 of FIG. 4 described above.

In operation 520, the state determiner 250 of the CP 200 may determine the current state of the electronic device. For example, the state determiner 250 may determine whether the current electronic device is lying face down on a desk. Specifically, it may be determined whether the display of the electronic device faces downward (gravity direction) using information obtained from the acceleration sensor.

In operation 530 , the state determiner 250 may transmit information according to the determination in operation 520 to the operation performer 260 . In operation 540, the operation performing unit 260 may determine an operation mode corresponding to the condition of the current electronic device based on the information received from the state determining unit 250 . For example, if it is determined in operation 520 that the display of the electronic device is positioned downward, it may be determined that the display OFF mode is applicable.

In operation 550, the operation executor 260 may transmit a control message (eg, DISPLAY OFF) to a component (eg, display) to which the display OFF mode is applied. In addition, in operation 560, the CP 200 may turn off all other sensors except for an acceleration sensor for determining a condition for canceling the display OFF mode. However, in some embodiments, the CP 200 may turn off only designated sensors in a specific mode, and unspecified sensors or sensors that must be turned on may maintain an ON state. When the display is set to an OFF state in operation 560, even if a notification message is received or a notification event occurs, notification provision through the display ON may be limited. However, even in this case, a notification by sound or vibration may be provided according to settings.

In operation 570, the scheduler 270 may increase the information collection period. For example, the CP 200 can check the acceleration sensor information every DRX operation cycle, but when there is no special movement in the electronic device, if the acceleration sensor information is checked in the Nth DRX operation period, the acceleration sensor information is displayed in the N+1th operation period. You may not request information. The CP 200 can monitor the change in the state in which the electronic device is placed and the change in the state in which the DISPLAY OFF mode must be canceled while appropriately increasing the time at which the acceleration sensor information is checked.

According to the information collection period adjusted in operation 570 , the state determiner 250 may collect acceleration sensor information in operation 580 . In operation 590, the state determiner 250 may determine whether to maintain the DISPLAY OFF mode or activate the AP 100 according to the single-shot state change. If it is determined to activate the AP 100, an operation corresponding to operation 480 or operation 490 of FIG. 4 may be performed.

In the embodiment of FIG. 5 , an exemplary operation of turning off the display when the electronic device is placed with the display facing downward has been described. In various embodiments, the same mode may be performed under different conditions. For example, in operation 510, when it is determined that the surroundings are dark through the illuminance sensor, the operation performing unit 250 may determine that the electronic device is in a bag or pocket by synthesizing illuminance information and current time information. Even in this case, the operation performing unit 260 may transmit a control message for turning off the display (operation 550) to the component 300 .

In addition to the above-described examples, in various embodiments, the CP 200 may perform a power saving operation in various ways based on various pieces of information obtainable by the electronic device. For example, when the display of the electronic device is placed to face upward in operation 520, the state determiner 250 may determine the current state of the electronic device by synthesizing various other information. For example, when it is determined that there is no movement of the electronic device by the location estimator 230 in a state in which the electronic device is placed facing upward, the state determiner 250 may aggregate the corresponding information and provide it to the operation performer 260 . there is. The operation performing unit 260 may determine whether the current state condition corresponds to the automatic operation mode 263 or the user customized mode 265 based on the provided information.

For example, when the operation performing unit 260 determines that the current electronic device corresponds to any user customized mode 265 (eg, a conference mode) by referring to the schedule, time, location information, etc., the operation performing unit The 260 may transmit a control message to each component to properly operate in a corresponding mode. For example, you can set all notifications OFF or silent notifications through DISPLAY ON without sound or vibration. Alternatively, the transmission/reception data may be stored in the memory 280 and provided when the conference mode is released.

6 illustrates an example of entering a CP-based low power mode according to various embodiments.

In operation 610, the electronic device may be performing a CP-based power saving operation. For example, while the AP 100 of the electronic device enters the sleep state, the CP 200 provides control authority for some functions, and the CP 200 collects status information of the electronic device according to the DRX operation cycle to activate only the minimum functions. This may save power.

In operation 620, the CP 200 may receive a message (eg, an SMS or an application notification message, etc.). The message may be externally received or may correspond to an event occurring inside the electronic device.

In operation 630, the CP 200 may deliver a control right return and AP activation message to the AP 100. The AP 100 may be activated to provide a notification for a corresponding message using a display of the electronic device or the like. In operation 630, the CP 200 transmits (simultaneously) the message (eg, a notification message) and a request message for causing the AP to perform the specified operation to the AP 100 so that the AP 100 can perform the specified operation immediately upon activation. can The specified operation may be set in various ways according to the type of message. For example, in the case of the aforementioned SMS message, the CP 200 may transmit a request message for generating vibration or sound immediately when the AP 100 is activated.

In operation 640, it may be determined whether a user response to the message occurs. When no response occurs in operation 640 , the CP 200 performs operation 650 , and when a user response occurs, the AP activation state may be continuously maintained in operation 670 .

In operation 650, the CP 200 may transmit a deactivation request message to the AP 100 without waiting until the AP 100 enters the sleep state. That is, in the various embodiments described above, in general, the CP-based power saving mode entry was performed at the request of the AP 100 while the AP 100 enters the inactive state, or when a predetermined time elapses or a predetermined condition is satisfied after entry, In the embodiment of FIG. 6 , the electronic device may enter the power saving mode while changing the AP 100 to the inactive state at the request of the CP 200 .

In operation 660 , the electronic device may receive a response to the request in operation 650 from the AP 100 . If the AP 100 accepts the request, the AP 100 may enter a sleep state and the CP 100 may acquire control rights for at least some functions for controlling the electronic device. If the AP 100 rejects the request according to various conditions, the electronic device may operate in a normal mode (eg, operation 670 ) in which the AP 100 maintains an activated state.

7 illustrates a CP-based RAT discovery control process according to various embodiments.

According to an embodiment, the CP performs continuous search for several different frequencies and/or different RATs even in the RRC idle state (RRC Idle mode) rather than the RRC connected state (Radio Resource Control Connected mode) for exchanging data with the base station. can do. For example, a search for available frequencies for a communication method such as 2G, 3G, or LTE and measurement of signal strength of the searched frequency may be performed. In the following description, an operation in which the electronic device searches for and measures a radio resource for a continuous service of wireless communication in an RRC idle state will be referred to as RAT search (Radio Access Technology search). In this document, RAT discovery is, for example, the same frequency as the serving cell in LTE RAT, or discovery for a different frequency (eg, LTE intra-frequency, LTE inter-frequency, Inter-RAT (UTRA, 3G), inter- RAT (GSM, 2G)) and PLMN search, it can be understood as a concept including all of the discovery of radio resources for a communication service. Such a RAT discovery operation results in power consumption of the electronic device. 7 illustrates an example of a process of determining a case in which the RAT discovery operation is unnecessary and controlling the RAT discovery operation to reduce power consumption.

Referring to FIG. 7 , in operation 710, the CP 200 may determine whether it is currently in an RRC idle state. If it is not in the RRC idle state, that is, in the RRC connected state, the CP 200 may not use the CP-based RAT discovery control process. For example, when information indicating that data transfer is started from the AP 100 is transmitted to the CP 200, the CP 200 may maintain the RRC Connected state (or change to the RRC Connected state). If information indicating that there is no more data to be transmitted (data transmission end information) is transmitted to the CP 200 from the AP 100, the CP 200 may enter the RRC idle state. In this case, the process proceeds to operation 720 . In other words, information on data transmission provided from the AP 100 may be a criterion for enabling/disabling the CP-based RAT discovery operation.

In operation 720, the CP 200 may determine whether the electronic device is in a stopped state. In an embodiment, the stationary state may be replaced with a stationary state. In this document, a static state may be understood as a state in which mobility of an electronic device is very low, including a stationary state, so that the possibility that the electronic device leaves a cell currently receiving a network service from a base station is very low. . In this case, since a continuous network service can be provided from the serving cell, another RAT discovery operation may be unnecessary. However, under a specific condition, another RAT discovery operation is required even when the electronic device is in a stopped or static state, which will be described with reference to operation 730 .

The CP 200 may obtain information on the movement of the electronic device from a sensor outside the CP (eg, the sensor 310 of FIG. 1 , the communication module 330, etc.). For example, the CP 200 requests a movement status of the electronic device from the sensor 310 (eg, an acceleration sensor) or the communication module 330 (eg, a GPS sensor), and obtains movement status information in response to the request to obtain the current electronic device status. It can be determined whether the device is in a stationary (static) state. This operation may be performed in the DRX cycle of the CP 200. For example, referring to FIG. 2 , in the state of entering the RRC idle mode, the CP 200 may request a movement state at T1 and obtain movement state information at T2 or T3. As a result of the determination, when the electronic device is not in a stopped state, the CP 200 may perform a RAT discovery operation. Of course, the CP 200 can perform the RAT discovery operation in all DRX cycles such as T1, T2, and T3, and the expression that the RAT discovery operation is performed in a specific period with respect to FIG. 7 is the RAT discovery operation of the previous DRX period does not exclude However, based on the information collected every DRX cycle, the CP 200 may check various conditions for RAT discovery and perform RAT discovery in a different way, or limit (omit) the RAT discovery itself. For example, the determination result When the electronic device is in the stopped state, if the condition after operation 730 is satisfied, the CP 200 may omit the RAT discovery operation or change the operation period in the DRX cycle after the time point at which operation 720 is performed.

When it is determined that the electronic device is in a stopped state, in operation 730, the CP 200 may determine the state of a radio resource. This operation may be performed by the CP 200 itself. That is, the process of FIG. 7 may be implemented by triggering the entire process by the AP 100, determining the state of the electronic device by a component external to the CP 200, and determining the state of the radio resource by the CP 200.

The CP 200 may comprehensively monitor the status of the current network (or the current serving cell), the signal status of a neighbor cell or another frequency/RAT, the signal change status of the serving cell, and the like. For example, if the signal state of the current serving cell is poor (eg, less than or equal to the reference RSSI value), or the signal level of the neighboring cell and the serving cell are similar, the CP 200 may cause A signal level may be changed to perform cell reselection. Here, fading refers to a signal received by the electronic device due to a change in the surrounding environment (eg, movement of surrounding people, objects, signal change, etc.) even when it is determined that the electronic device is stationary, such as when the electronic device is placed on a table. may mean that there is a change in Accordingly, in operation 730, the CP 200 may determine the state of a radio resource such as a signal strength of a serving cell and/or an adjacent cell. In addition to this, the CP 200 may determine a previous search/measure time and a radio signal condition for various frequencies. For example, in an embodiment, the CP 200 continuously omits a search/measure operation after a search/measurement time for a specific frequency, and when it is determined that a predetermined time has elapsed from the search/measurement time, the CP 200 searches for a specific frequency again /Measurement can be performed. Through such an operation, it is possible to prevent a problem from occurring in the communication service.

In operation 740, the CP 200 may determine whether RAT discovery is necessary based on the information collected in operations 720 to 730. If it is determined that RAT discovery is unnecessary, the CP 200 may limit RAT discovery or change a discovery period in operation 750 . For example, the CP 200 may block RAT discovery during a DRX operation performed later, or may change the RAT discovery period to a relatively long (eg, one RAT discovery when DRX is repeated 5 times).

If it is determined that RAT discovery is necessary, for example, if it is determined that the electronic device is moving or the network state is unstable, the CP 200 may continuously perform the RAT discovery operation in operation 760 .

According to an embodiment, even if power consumption is reduced by limiting RAT discovery or setting a long RAT discovery cycle, when it is determined that such an operation affects connectivity performance of an electronic device, limit RAT discovery This can be turned off. For example, when various exit conditions using various information are satisfied, such as when a condition that is determined to be highly likely to cause an out of service (OOS) state is satisfied by the RAT search restriction, the CP 200 is the RAT Restrictions on search can be lifted. For example, in CP 200, when it is determined that the terminal leaves the stationary state, when the RSRP value of the serving cell changes by a certain level or more, when the RAT search for each frequency is omitted for a certain time or more, the serving cell RAT search restrictions can be released by considering escape conditions such as when the RSRP value of is less than or equal to a certain value.
