This application also claims priority to Chinese Patent Application No. 202311466259.0, filed with the China National Intellectual Property Administration on November 3, 2023, entitled "Interface Display Method and Related Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of terminal technology, and in particular to a control method and related device. Background Technology

[0003] Some electronic devices support both cellular and satellite communication capabilities. In scenarios where a user is in an area with no or poor cellular coverage, preventing them from using their electronic device to contact the outside world, a user can operate their device to connect to a satellite network for satellite communication. To conserve battery life while awaiting rescue, the user can disconnect the device from the satellite network after completing satellite communication.

[0004] However, in some implementations, electronic devices may experience shorter battery life after disconnecting from the satellite network, preventing users from using them for extended periods. Summary of the Invention

[0005] This application provides a control method and related apparatus, which are applied in the field of terminal technology.

[0006] In some embodiments, after the electronic device disconnects from the satellite network, a pop-up window is displayed to prompt the user to turn off the modem. Upon receiving the user's instruction to turn off the modem, the electronic device turns off the modem to reduce the power consumption of the modem, thereby reducing the power consumption of the electronic device after disconnecting from the satellite network and extending the battery life of the electronic device.

[0007] In a first aspect, embodiments of this application propose a control method, comprising: At a first moment, an electronic device receives an operation to turn off satellite communication mode, and the electronic device disconnects from the satellite network. At a second moment, the electronic device displays a first pop-up window. The first pop-up window includes a first control and a first prompt message, the first prompt message being used to prompt whether to turn off cellular communication. The second moment is later than the first moment. At a third moment, in response to an operation on the first control, the electronic device controls its modem to be turned off. The third moment is later than the second moment.

[0008] In this way, when the electronic device disconnects from the satellite network, a pop-up window prompts the user to turn off the modem. When the user's action on the electronic device is determined to be turning off the modem, the electronic device controls the modem to remain off. This reduces the modem's power consumption when the electronic device is disconnected from the satellite network, thereby reducing the power consumption of the electronic device and allowing it to maintain a longer battery life. If the user is in an environment with no cellular network coverage or poor cellular network coverage and needs to wait for rescue, the longer battery life of the electronic device is beneficial for rescue efforts.

[0009] In one possible implementation, between the first and second moments, the method further includes: at a fourth moment, the electronic device displays a second pop-up window. The second pop-up window includes a second control and a second prompt message, the second prompt message indicating whether to enter power-saving mode. The electronic device displays the first pop-up window in response to an operation on the second control.

[0010] In this way, by displaying a second pop-up window before the first pop-up window appears, the electronic device can be put into a state where the modem is on and the transceiver module associated with flight mode is off under the user's operation. This reduces the power consumption of the transceiver module associated with flight mode when the electronic device is searching for cellular networks, thus allowing the electronic device to maintain a longer battery life.

[0011] In one possible implementation, the method further includes: at a fifth moment, the electronic device receives an operation to enable satellite communication mode, and the electronic device connects to the satellite network. The fifth moment is later than the third moment. At a sixth moment, the electronic device receives an operation to disable satellite communication mode, and the electronic device disconnects from the satellite network. The sixth moment is later than the fifth moment. At a seventh moment, the electronic device displays a first pop-up window. The first pop-up window also includes a third control. The seventh moment is later than the sixth moment. At an eighth moment, in response to an operation on the third control, the electronic device controls the modem to be turned on. The eighth moment is later than the seventh moment.

[0012] This allows electronic devices to keep searching for cellular networks, enabling them to connect to the cellular network when it is found, thus facilitating real-time cellular communication for users.

[0013] In one possible implementation, after the eighth time step, the process further includes: the modem searching for the cellular network according to a first periodic network search method. The search interval of the first periodic network search method increases sequentially. At the ninth time step, the electronic device receives an operation to initiate a communication service, and the modem searches for the cellular network according to a second periodic network search method. The search interval of the second periodic network search method increases sequentially, and within the same periodic search interval, the search interval of the second periodic network search method is smaller than the search interval of the first periodic network search method.

[0014] In this way, the search interval of the first periodic network search method increases sequentially. By increasing the search interval, the modem's power consumption during network search can be reduced. When the electronic device receives an operation to initiate a communication service, the modem searches for cellular networks according to the second periodic network search method, which helps the electronic device find a cellular network as quickly as possible, thus improving the user experience.

[0015] In one possible implementation, in the first periodic net-searching method, when the net-searching interval in the first periodic net-searching method reaches a first net-searching interval threshold, the net-searching interval in the first periodic net-searching method no longer increases. In the second periodic net-searching method, when the net-searching interval in the second periodic net-searching method reaches a second net-searching interval threshold, the net-searching interval in the second periodic net-searching method no longer increases. The second net-searching interval threshold is smaller than the first net-searching interval threshold.

[0016] This reduces the probability of not being able to find a cellular network.

[0017] In one possible implementation, before the modem searches for a cellular network according to the second periodic network search method, the method further includes: the electronic device determining whether the modem's network search interval is greater than a network search interval threshold. When the electronic device determines that the modem's network search interval is greater than the network search interval threshold, the modem searches for a cellular network according to the second periodic network search method.

[0018] This allows for a balance between timely cellular network searches and reduced network search power consumption.

[0019] In one possible implementation, the method further includes: the electronic device determining whether its location is within a preset geofence. The preset geofence is an area without cellular network coverage or where cellular network access is unavailable. When the electronic device determines that its location is within the preset geofence, the modem stops searching for cellular networks.

[0020] If the electronic device is within a preset geofence, the modem's network search is considered an invalid network search. The modem can stop searching to reduce the power consumption of invalid network searches.

[0021] In one possible implementation, at the third moment, in response to the operation of the first control, the electronic device further includes: the electronic device controlling at least one of the electronic device's Wi-Fi, Bluetooth BT, NFC, or infrared IR to be in a turned-off state.

[0022] This reduces the power consumption of electronic devices, allowing them to maintain a longer battery life.

[0023] In one possible implementation, at the eighth moment, in response to the operation of the third control, the electronic device controls the electronic device's Wi-Fi, Bluetooth, NFC, and infrared to be in a turned-off state.

[0024] This reduces the power consumption of Wi-Fi, BT, NFC, and IR, thereby reducing the power consumption of electronic devices and allowing them to maintain a longer battery life.

[0025] In one possible implementation, the electronic device displays a first pop-up window, which includes: the electronic device determining whether the communication service prior to disconnecting from the satellite network was a satellite communication service. Satellite communication services include one or more of the following: satellite voice calls, sending and receiving satellite SMS messages, satellite video communication, and satellite voice communication; if the electronic device determines that the communication service prior to disconnecting from the satellite network was a satellite communication service, then the electronic device displays the first pop-up window.

[0026] In this way, it can be accurately determined that the operation intention corresponding to the electronic device disconnecting from the satellite network is a power-saving intention. The electronic device can then display a first pop-up window to prompt the user to perform a power-saving operation, which can improve the user experience.

[0027] In one possible implementation, the electronic device displays a first pop-up window, which includes: the electronic device determining whether the communication service prior to disconnecting from the satellite network was a satellite communication service. Satellite communication services include one or more of the following: satellite calls, sending and receiving satellite SMS messages, satellite video communication, and satellite voice communication; if the electronic device determines that the communication service prior to disconnecting from the satellite network was not a satellite communication service, then it uses the electronic device's most recently stored location information to determine whether the electronic device is in an area without cellular network coverage. If the electronic device determines that it is in an area without cellular network coverage, then the electronic device displays the first pop-up window.

[0028] This prompts users to perform power-saving operations, improving the user experience.

[0029] Secondly, embodiments of this application provide a control method, the method comprising: an electronic device receiving an operation to disable satellite communication; in response to receiving the operation to disable satellite communication, the electronic device disconnecting from a satellite network; after the electronic device disconnects from the satellite network, the electronic device displaying a fourth pop-up window; the fourth pop-up window including a fourth control for enabling a first power-saving mode; in response to receiving an operation on the fourth control, enabling the first power-saving mode.

[0030] In this way, when the electronic device is disconnected from the satellite network, a fourth pop-up window will appear, prompting the user whether to enable the first power-saving mode. Upon receiving the instruction to enable the first power-saving mode, the user can enable the first power-saving mode to reduce the power consumption of the electronic device.

[0031] In one possible implementation, the fourth pop-up window also includes a third prompt message, which is used to indicate that satellite communication has been detected as enabled.

[0032] It is understood that "satellite communication function enabled" can be interpreted as "satellite communication function being turned on" and / or "satellite communication service being used." "Satellite communication function being turned on" can mean that the electronic device has performed one or more of the following: satellite search, satellite pairing, or establishing a communication connection with a satellite. "Satellite communication function being enabled" can be detected for example: the satellite communication function being detected as disabled, or the termination of a satellite communication service being detected (e.g., a satellite call being ended).

[0033] In this way, detecting that satellite communication has been enabled can indicate that there is no cellular network coverage or poor cellular signal quality in the area where the electronic device is located, thus prompting the user to turn on the first power-saving mode, which can improve the user experience.

[0034] In one possible implementation, before the electronic device displays the fourth pop-up, the method further includes: the electronic device's cellular modem searching for cellular networks. The display of the fourth pop-up includes: the electronic device displaying the fourth pop-up if the cellular modem fails to search for a cellular network within a first preset time period.

[0035] If the search for a cellular network fails within the first preset time period, it indicates that the electronic device is located in an area with no cellular network coverage or poor cellular signal quality. In this case, the electronic device displays a fourth pop-up window, prompting the user to activate the first power-saving mode to reduce the power consumption of the electronic device.

[0036] In one possible implementation, activating a first power-saving mode includes at least one of the following: controlling the electronic device's cellular modem to be in a powered-off or low-power state; or controlling the electronic device's Wi-Fi communication module to be in a powered-off or low-power state; or controlling the electronic device's Bluetooth BT communication module to be in a powered-off or low-power state; or controlling the electronic device's Near Field Communication (NFC) module to be in a powered-off or low-power state; or controlling the electronic device's Infrared (IR) module to be in a powered-off or low-power state.

[0037] Control the display screen of electronic devices to adjust the way the interface is displayed in order to reduce the power consumption of electronic devices.

[0038] It is understandable that a component being in a "shutdown" state can mean that the component is powered off. A component being in a "low-power" state can mean that the component is not powered off but cannot function properly. The power consumption of a component in a shut-down or low-power state is less than the power consumption of a component in an active state. A component being in an active state indicates that the component can function normally. Controlling the display screen of an electronic device to adjust the display mode of the interface can reduce the power consumption of the electronic device. For example, the electronic device adjusts the display brightness to a first brightness threshold, and / or adjusts the display refresh rate to a first refresh rate threshold. This can reduce the power consumption of the electronic device.

[0039] In one possible implementation, before the electronic device receives an operation to disable satellite communication, the method further includes: establishing a communication connection between the electronic device and the satellite network. After the electronic device establishes a communication connection with the satellite network, the electronic device displays a sixth pop-up window, which includes a sixth control for enabling a second power-saving mode. In response to receiving an operation on the sixth control, the second power-saving mode is enabled. This reduces the power consumption of the electronic device.

[0040] In one possible implementation, enabling a second power-saving mode includes controlling the display screen of the electronic device to adjust the way the interface is displayed in order to reduce the power consumption of the electronic device.

[0041] In one possible implementation, before the electronic device receives an operation to disable satellite communication, the method further includes: enabling satellite communication services on the electronic device. Satellite communication services include one or more of the following: satellite calling, sending and receiving satellite text messages, satellite video communication, and satellite voice communication.

[0042] Enabling satellite communication on an electronic device indicates that there is no cellular network or the cellular signal quality is poor in the area where the device is located. Therefore, upon receiving an instruction to disable satellite communication, the electronic device can prompt the user to activate its first power-saving mode to reduce power consumption and extend battery life.

[0043] In one possible implementation, the method further includes: after the satellite communication service ends, the electronic device displays a seventh pop-up window, which includes a seventh control for enabling a third power-saving mode. In response to receiving an operation on the seventh control, the third power-saving mode is enabled. This reduces the power consumption of the electronic device.

[0044] In one possible implementation, after receiving an operation on the fourth control, the method further includes: the electronic device displaying an eighth pop-up window, which includes an eighth control for reducing the power consumption of the cellular modem. In response to receiving an operation on the eighth control, the cellular modem of the electronic device is controlled to be in a powered-off state or a low-power state. This reduces the power consumption of the electronic device.

[0045] Thirdly, embodiments of this application provide a control method, the method comprising: at a tenth moment, an electronic device receives an operation to turn off satellite communication mode, and the electronic device disconnects from the satellite network. At an eleventh moment, the electronic device displays a fourth pop-up window. The fourth pop-up window includes a fourth control and a third prompt message, the third prompt message being used to prompt whether to enable the super power saving mode. The eleventh moment is later than the tenth moment. At a twelfth moment, in response to the operation on the fourth control, the super power saving mode is enabled. The twelfth moment is later than the eleventh moment.

[0046] In this way, when the electronic device is disconnected from the satellite network, a fourth pop-up window will appear, prompting the user whether to enable the super power saving mode. Upon receiving the enable command, the user can enable the super power saving mode to reduce the power consumption of the electronic device.

[0047] In one possible implementation, enabling a super power-saving mode includes: controlling the modem of the electronic device to be in a low-power state, and controlling the electronic device's Wi-Fi, Bluetooth, NFC, and IR to be turned off, as well as controlling the screen brightness of the electronic device to a preset brightness. The cellular modem being in a low-power state can mean that the cellular modem does not search for cellular networks or searches for cellular networks at a lower frequency or longer interval.

[0048] In this way, by shutting down multiple modules and reducing screen brightness, the electronic device is put into a super power-saving mode to reduce power consumption. The modem being in a low-power state indicates that it is not powered off, and it can be quickly restored to working status when the user needs to.

[0049] In one possible implementation, in response to an operation on the fourth control, the method further includes: the electronic device displaying a fifth pop-up window. The fifth pop-up window includes a fifth control and a fourth prompt message, which again prompts whether to enable the Super Power Saving Mode, and the limitations on the electronic device's functions and applications after enabling Super Power Saving Mode. Enabling Super Power Saving Mode includes: starting Super Power Saving Mode upon receiving an operation on the fifth control.

[0050] This allows a fifth pop-up window to appear before the fourth one, prompting the user again whether to enable the Super Power Saving Mode and indicating the limitations on the electronic device's functions and applications after enabling Super Power Saving Mode. Users can then decide whether to enable Super Power Saving Mode based on the prompts, thus improving the user experience.

[0051] In one possible implementation, before the electronic device displays the fourth pop-up window, the method further includes: the modem of the electronic device searching for cellular networks, and determining whether the modem has successfully searched for a network from the time the modem begins searching for cellular networks until a first preset time period is reached. Displaying the fourth pop-up window includes: if the modem fails to search for a network, the electronic device displays the fourth pop-up window.

[0052] This allows the system to prompt the user to activate Ultra Power Saving Mode when a network search fails. An unsuccessful network search indicates a lack of cellular network coverage or poor cellular signal quality in the user's area; activating Ultra Power Saving Mode reduces the power consumption of electronic devices.

[0053] In one possible implementation, the method further includes: at the thirteenth moment, the communication connection between the electronic device and the satellite network is established, and the electronic device displays a sixth pop-up window. The sixth pop-up window includes a sixth control and a fifth prompt message, which prompts whether to enable screen power saving mode. Screen power saving mode is a mode where the refresh rate of the electronic device's display is a preset refresh rate, and / or the brightness of the electronic device's display is a preset brightness. The thirteenth moment is earlier than the tenth moment. At the fourteenth moment, in response to the operation of the sixth control, screen power saving mode is enabled. The fourteenth moment is later than the thirteenth moment.

[0054] This allows the user to be prompted to turn on screen power saving mode once the communication connection with the satellite network is established, thereby reducing the power consumption of electronic devices.

[0055] In one possible implementation, before the tenth moment, the method further includes: enabling satellite communication services on electronic devices. Satellite communication services include one or more of the following: satellite calling, sending and receiving satellite text messages, satellite video communication, and satellite voice communication.

[0056] This allows the device to disconnect from the satellite network and prompt the user to activate a super power-saving mode when the electronic device has started satellite communication services and received an instruction to turn off satellite communication mode, thereby reducing the power consumption of the electronic device. The fact that a user has used satellite communication services could indicate that the user's area lacks cellular network coverage or has poor cellular signal quality, or it could mean that the user is waiting for rescue. Therefore, prompting the user to activate the super power-saving mode can reduce the power consumption of the electronic device while waiting for rescue.

[0057] In one possible implementation, the method further includes: at the fifteenth moment, receiving an operation to terminate satellite communication services, the electronic device displays a sixth pop-up window, which includes a sixth control and a fifth prompt message, indicating whether to enable screen power saving mode. Screen power saving mode is a mode where the refresh rate of the electronic device's display is a preset refresh rate, and / or the brightness of the electronic device's display is a preset brightness. Satellite communication services include one or more of the following: satellite calls, sending and receiving satellite SMS, satellite video communication, and satellite voice communication. The fifteenth moment is earlier than the tenth moment. At the sixteenth moment, in response to the operation on the sixth control, screen power saving mode is enabled. The sixteenth moment is later than the fifteenth moment.

[0058] In this way, when satellite communication services are terminated, users can be prompted to turn on screen power saving mode to reduce the power consumption of electronic devices.

[0059] In one possible implementation, before the tenth moment, the method further includes: the electronic device searching for satellites. If the electronic device detects a satellite, it performs satellite-to-satellite alignment. Once satellite alignment is complete, the electronic device establishes a communication connection with the detected satellite.

[0060] Thus, before connecting to the satellite network, the electronic equipment performs satellite search, satellite alignment, and communication connection establishment to achieve this connection. For details on the specific implementation principles of satellite search, satellite alignment, and communication connection, please refer to [link to relevant documentation]. Figures 9C-9E The specific implementation principle shown will not be elaborated here.

[0061] Fourthly, embodiments of this application provide an electronic device comprising: a processor and a memory. The memory stores computer-executable instructions. The processor executes the computer-executable instructions stored in the memory, causing the electronic device to perform the method as described in the first aspect, any possible implementation of the first aspect, the second aspect, or any possible implementation of the second aspect.

[0062] Fifthly, embodiments of this application provide a computer-readable storage medium storing a computer program. When executed by a processor, the computer program implements the method as described in the first aspect, any possible implementation of the first aspect, the second aspect, any possible implementation of the second aspect, the third aspect, or any possible implementation of the third aspect.

[0063] Sixthly, embodiments of this application provide a computer program product, which includes a computer program that, when run, causes a computer to perform the method described in the first aspect, any possible implementation of the first aspect, the second aspect, any possible implementation of the second aspect, the third aspect, or any possible implementation of the third aspect.

[0064] In a seventh aspect, embodiments of this application provide a chip system including at least one processor and a communication interface, wherein the communication interface and at least one processor are interconnected via a line, and at least one processor is used to run a computer program or instructions to perform the method as described in the first aspect, any possible implementation of the first aspect, the second aspect, any possible implementation of the second aspect, the third aspect, or any possible implementation of the third aspect.

[0065] It should be understood that aspects four through seven of this application correspond to the technical solutions of aspect one, aspect two, or aspect three of this application, and the beneficial effects achieved by each aspect and the corresponding feasible implementation are similar, and will not be repeated here.

[0092] To facilitate a clear description of the technical solutions in the embodiments of this application, some terms and technologies involved in the embodiments of this application will be briefly introduced below:

[0093] 1. Electronic equipment

[0094] The electronic devices in this application embodiment may include handheld devices with image processing functions, vehicle-mounted devices, etc. For example, some electronic devices include: mobile phones, tablets, PDAs, laptops, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to wireless modems, in-vehicle devices (such as vehicle infotainment systems), wearable devices, terminal devices in 5G networks, or future evolution of public land mobile communication networks. Terminal devices in a network (PLMN), etc., are not limited to this in the embodiments of this application.

[0095] By way of example and not limitation, in this embodiment, the electronic device can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as hearing aids, glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0096] Furthermore, in this embodiment of the application, the electronic device can also be a terminal device in the Internet of Things (IoT) system. IoT is an important part of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection.

[0097] The electronic devices in the embodiments of this application may also be referred to as: terminal equipment, user equipment (UE), mobile station (MS), mobile terminal (MT), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device, etc.

[0098] In this embodiment, the electronic device or various network devices include a hardware layer, an operating system layer running on top of the hardware layer, and an application layer running on top of the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also called main memory). The operating system can be any one or more computer operating systems that implement business processing through processes, such as Linux, Unix, Android, iOS, or Windows. The application layer includes applications such as a camera, browser, address book, word processing software, and instant messaging software.

[0099] 2. Out-of-service (OOS) state

[0100] Out-of-Service (OOS) status refers to a state where an electronic device is unable to remain on a cell network due to reasons such as no cellular network signal, poor cellular network signal strength, or loss of radio resource control connection. OOS status indicates that the electronic device has disconnected from the cellular network.

[0101] 3. Search the web

[0102] Network search can refer to the process of searching for available networks after an electronic device has disconnected from the network and before it reconnects.

[0103] For example, after an electronic device is powered on or disconnected from a Public Land Mobile Network (PLMN), the electronic device searches for and selects a PLMN to access the PLMN and performs the following actions.

[0104] For example, the network search process may include: initialization → PLMN selection → frequency scanning → cell selection and camping → random access → attach.

[0105] Initialization may include reading user settings and other network search-related information stored in the non-volatile memory (NV) within the subscriber identification module (SIM) card, and initializing system settings.

[0106] PLMN selection, also known as PLMN search, refers to an electronic device scanning PLMN information in its area to generate a list of available PLMNs. This list includes PLMN identifiers, operating frequencies, and PLMN information stored on the Universal Subscriber Identity Module (USIM) card. The USIM is part of the SIM card.

[0107] Frequency scanning, also known as frequency sweeping, is divided into two types: system scan and band scan. System scan scans historical frequency points. When system scan fails to find all historical frequency points, band scan is performed.

[0108] Cell selection, also known as cell search, is the process of finding a PCI or PSC from a frequency point through a series of synchronization processes such as matching.

[0109] Cell selection and cell search can refer to the selection of cells in Long Term Evolution (LTE) based on the principle of maximum signal strength (or S criterion).

[0110] Random access can be used to obtain uplink synchronization and uplink scheduling resources.

[0111] Attachment can refer to electronic devices registering with the core network, establishing signaling radio bearer (SRB)2 and data radio bearer (DRB), and establishing a default bearer.

[0112] It is understandable that cellular networks belong to PLMN.

[0113] 4. OOS search mechanism.

[0114] OOS network search mechanism can refer to a periodic network search method.

[0115] For example, to reduce the power consumption of electronic devices during network search, a network search method is used where, under conditions of no cellular network coverage, poor cellular network signal strength, or when the electronic device is slightly moving or stationary, the network search interval for periodic network searches is progressively increased, and the network search interval no longer increases when it reaches a network search interval threshold. The network search interval can refer to the duration between two adjacent network search cycles.

[0116] The phrase "electronic device in the network search interval" indicates that the electronic device has stopped searching for a network. The network search interval can also be referred to as the sleep duration. "Electronic device in a state of slight movement or stillness" can be understood as the electronic device's movement speed being less than a speed threshold.

[0117] The OOS network search mechanism can also be called the OOS network search strategy.

[0118] 5. User Interface

[0119] A user interface, also simply called an interface, can be understood as the medium through which an application or operating system interacts and exchanges information with the user. It facilitates the conversion between the internal form of information and a form acceptable to the user. A common form of user interface is the graphical user interface (GUI), which refers to a user interface related to computer operation displayed graphically. It can be an icon, window, control, or other interface element displayed on the screen of an electronic device. Controls can include visual interface elements such as icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, and widgets.

[0120] 6. Other terms

[0121] In this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0122] In this application embodiment, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0123] In this application's embodiments, "at...time" can refer to the instant a certain situation occurs, or it can refer to a period of time after the certain situation occurs; this application's embodiments do not specifically limit this. Furthermore, the display interface provided in this application's embodiments is merely an example, and the display interface may include more or less content.

[0124] Some electronic devices support cellular communication over cellular networks and satellite communication over satellite networks. In scenarios where a user is in an area with no cellular network coverage or poor cellular signal quality, and the user needs rescue, after the user finishes communicating with another electronic device or rescue platform over a satellite network using their electronic device, the user can operate the electronic device to disconnect from the satellite network and wait for rescue.

[0125] For example, a user can touch the display screen of an electronic device to open a settings application. The electronic device can display the settings application interface. The settings application interface includes a satellite on / off control. For example, the satellite communication module of the electronic device is in a disabled state by default at the factory. The user can touch the satellite on / off control on the interface to turn on the satellite communication module and enable the electronic device to connect to the satellite network. The touch operation can include a tap or a swipe.

[0126] After satellite communication ends, similarly, users can touch the screen of their electronic device to open the settings app. On the settings app interface displayed on the electronic device, users can touch the satellite switch control to turn off the satellite communication module, thus disconnecting the electronic device from the satellite network.

[0127] In one possible implementation, flight mode is activated when the electronic device turns on the satellite communication module, and deactivates when the satellite communication module is turned off. Signal transceiver modules associated with flight mode include modems, Wi-Fi, Bluetooth (BT), near-field communication (NFC), and infrared (IR) transceiver modules.

[0128] Enabling flight mode when the satellite communication module of an electronic device is activated can reduce interference from signal transceivers such as modem, Wi-Fi, BT, NFC, and IR on the satellite communication module's signal transmission and reception, thereby improving satellite communication quality.

[0129] For example, when an electronic device is in flight mode, the modem, Wi-Fi, BitTorrent (BT), NFC, and IR transceiver modules are all turned off. This reduces interference from the signal transmission and reception of these modules on the satellite communication module. When the electronic device turns off the satellite communication module, it exits flight mode. When the electronic device exits flight mode, the modem, Wi-Fi, BT, NFC, and IR may or may not be in flight mode.

[0130] It is understandable that when an electronic device exits airplane mode, the control of signal transceiver modules such as Modem, Wi-Fi, BT, NFC, and IR may be implemented in two ways: Method 1 and Method 2.

[0131] Method 1: When the electronic device is in airplane mode, the modem, Wi-Fi, Bluetooth, NFC, and IR transceiver modules are all turned off. When the electronic device is out of airplane mode, the modem, Wi-Fi, Bluetooth, NFC, and IR transceiver modules are all turned on.

[0132] Method 2: When the electronic device is in airplane mode, the modem, Wi-Fi, BitTorrent, NFC, and IR transceiver modules are all turned off. When the electronic device exits airplane mode, these modules return to their pre-airflow state. It's important to understand that the transceiver modules could have been either on or off before airplane mode was activated.

[0133] The signal transceiver module consumes power when it is turned on, increasing the power consumption of the electronic device. Therefore, if the signal transceiver module remains on after the electronic device has exited flight mode, it may result in a shorter battery life, potentially affecting rescue operations.

[0134] For example, if the modem, Wi-Fi, BT, NFC, and IR are all turned on before the electronic device is put into airplane mode, Figure 1 The diagram illustrates possible scenarios of electronic devices connecting to and disconnecting from satellite networks.

[0135] When electronic devices connect to a satellite network, the electronic devices can display... Figure 1 The interface shown in 'a'. For example... Figure 1 The interface shown in 'a' includes icon 101. Icon 101 can be used to indicate the strength of the satellite signal and also to indicate that the satellite communication module is in the active state.

[0136] exist Figure 1 On the interface shown in Figure 'a', users can perform a pull-down operation from the top of the electronic device or a pull-up operation from the bottom of the electronic device. The electronic device can then display something like... Figure 1 The control center interface shown in b is as follows. Figure 1 The interface shown in b includes controls 102, 103, 104, 105, 106, 107, and 108.

[0137] Control 102 can be used to turn Wi-Fi on or off. Control 103 can be used to turn BitTorrent on or off. Control 104 can be used to turn airplane mode on or off. Control 105 can be used to turn the modem on or off. Control 106 can be used to turn NFC on or off. Control 107 can be used to turn IR on or off. Control 108 is used to adjust the brightness of the display screen. Control 104 is highlighted, while controls 102, 103, 105, 106, and 107 are not highlighted.

[0138] Control 104 highlighted indicates that the electronic device is in airplane mode. If control 104 is not highlighted, it indicates that the electronic device is out of airplane mode. For controls 102, 103, 105, 106, and 107, highlighting indicates that their respective modules are enabled, while non-highlighting indicates that their respective modules are disabled. For control 108, the longer the highlight bar, the higher the screen brightness.

[0139] exist Figure 1On the interface shown in Figure 'a', users can perform touch operations to turn off the satellite communication module, thereby disconnecting the electronic device from the satellite network. When the electronic device disconnects from the satellite network, it can display... Figure 1 The interface shown in 'c'. Figure 1 The interface shown in 'c' includes icons 109, 110, and 111, with icon 101 no longer present. Icon 109 indicates Wi-Fi signal strength. Icon 110 indicates NFC is enabled. Icon 111 indicates BitTorrent (BT) is enabled. The absence of icon 101 in this interface indicates the satellite communication module is disabled.

[0140] exist Figure 1 On the interface shown in 'c', users can perform a pull-down operation from the top of the electronic device or a pull-up operation from the bottom of the electronic device. The electronic device can then display something like... Figure 1 The control center interface is shown as 'd' in the diagram. Figure 1 The interface shown in d includes highlighted control 102, highlighted control 103, non-highlighted control 104, highlighted control 105, highlighted control 106, highlighted control 107, and control 108.

[0141] from Figure 1 From points a, b, c, and d, we can see that when the electronic device is connected to the satellite network, the satellite communication module is on, while the modem, Wi-Fi, BitTorrent (BT), NFC, and IR are all off, reducing the power consumption of these components. When the electronic device disconnects from the satellite network, the satellite communication module is off, but the modem, Wi-Fi, BT, NFC, and IR are on. While this reduces the power consumption of the satellite communication module, it increases the power consumption of the modem, Wi-Fi, BT, NFC, and IR. Compared to the power consumption when the electronic device is connected to the satellite network, the power consumption increases after disconnection. Therefore, the battery life of the electronic device may be shorter after exiting airplane mode. Among the modem, Wi-Fi, BT, NFC, and IR, the modem consumes the most power during network search. By managing the modem, its network search power consumption can be reduced, thereby reducing the power consumption of the electronic device.

[0142] In view of this, this application provides a control method that displays a pop-up window to prompt the user to turn off the modem after the electronic device disconnects from the satellite network. When the user's operation to turn off the modem is received, the electronic device turns off the modem to reduce the power consumption of the modem, thereby reducing the power consumption of the electronic device after disconnecting from the satellite network and making the electronic device have a longer battery life.

[0143] The control method proposed in this application will be described below with reference to some embodiments.

[0144] Figure 2 A schematic diagram of the structure of the electronic device 200 is shown.

[0145] Electronic device 200 may include processor 210, external memory interface 220, internal memory 121, universal serial bus (USB) interface 230, charging management module 240, power management module 241, battery 242, antenna 1, antenna 2, mobile communication module 250, wireless communication module 260, audio module 270, speaker 270A, receiver 270B, microphone 270C, headphone jack 270D, sensor module 280, button 290, motor 291, indicator 292, camera 293, display screen 294, and subscriber identification module (SIM) card interface 295, etc. The sensor module 280 may include a pressure sensor 280A, a gyroscope sensor 280B, a barometric pressure sensor 280C, a magnetic sensor 280D, an accelerometer sensor 280E, a distance sensor 280F, a proximity sensor 280G, a fingerprint sensor 280H, a temperature sensor 280J, a touch sensor 280K, an ambient light sensor 280L, a bone conduction sensor 280M, etc.

[0146] It is understood that the structures illustrated in the embodiments of the present invention do not constitute a specific limitation on the electronic device 200. In other embodiments of this application, the electronic device 200 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0147] Processor 210 may include one or more processing units, such as an application processor (AP), a modem-demodulator (Modem, also known as a baseband processor), a satellite communication module, a controller, and a satellite protocol stack. These different units may be independent devices, located in different devices, or integrated into one or more devices.

[0148] The processor 210 may also include a memory for storing instructions and data.

[0149] The wireless communication function of electronic device 200 can be implemented through antenna 1, antenna 2, mobile communication module 250, wireless communication module 260, modem processor, satellite communication module, baseband processor and satellite protocol stack, etc.

[0150] Antenna 1 and antenna 2 are used to transmit and receive electromagnetic wave signals. Each antenna in electronic device 200 can be used to cover one or more communication frequency bands. Different antennas can also be multiplexed to improve antenna utilization. For example, antenna 1 can be multiplexed as a diversity antenna for a wireless local area network. In some other embodiments, the antennas can be used in conjunction with a tuning switch.

[0151] The mobile communication module 250 can provide solutions for wireless communication, including 2G / 3G / 4G / 5G, applied to the electronic device 200. The mobile communication module 250 may include at least one filter, switch, power amplifier, low noise amplifier (LNA), etc. The mobile communication module 250 can receive electromagnetic waves via antenna 1, and perform filtering, amplification, and other processing on the received electromagnetic waves before transmitting them to a modem processor for demodulation. The mobile communication module 250 can also amplify the signal modulated by the modem processor and convert it into electromagnetic waves for radiation via antenna 1. In some embodiments, at least some functional modules of the mobile communication module 250 may be housed in the processor 210. In some embodiments, at least some functional modules of the mobile communication module 250 and at least some modules of the processor 210 may be housed in the same device.

[0152] A modem processor may include a modulator and a demodulator. The modulator modulates a low-frequency baseband signal to be transmitted into a mid-to-high frequency signal. The demodulator demodulates a received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to a baseband processor for processing. After processing by the baseband processor, the low-frequency baseband signal is transmitted to an application processor. The application processor outputs sound signals through an audio device (not limited to speaker 270A, receiver 270B, etc.) or displays images or videos through a display screen 294. In some embodiments, the modem processor may be a separate device. In other embodiments, the modem processor may be independent of the processor 210 and housed within the same device as the mobile communication module 250 or other functional modules. The modem processor can be used for searching and accessing cellular networks, detecting the strength of cellular network signals, and maintaining the cell dwell status of electronic devices. A modem processor (Modem) may be simply referred to as a modem.

[0153] The wireless communication module 260 can provide solutions for wireless communication applications on the electronic device 200, including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), location-based service (LBS) modules, satellite mobile communication systems, frequency modulation (FM), near field communication (NFC), and infrared (IR) technologies. The wireless communication module 260 can be one or more devices integrating at least one communication processing module. The wireless communication module 260 receives electromagnetic waves via antenna 2, performs frequency modulation and filtering of the electromagnetic wave signals, and sends the processed signal to processor 210. The wireless communication module 260 can also receive signals to be transmitted from processor 210, perform frequency modulation and amplification, and convert them into electromagnetic waves for radiation via antenna 2.

[0154] The satellite communication module can be used for satellite network search and access. It also processes received satellite signals and transmits them to the protocol stack for further processing. The processed satellite signals are then passed to the application processor. The satellite communication module can also receive communication signals transmitted by the application processor through the protocol stack, process them, and transmit them through antenna 2. In some embodiments, the satellite communication module can be a separate device. In other embodiments, the satellite communication module can be independent of processor 210 and housed within the same device as the wireless communication module 260 or other functional modules.

[0155] In some embodiments of this application, a modem may also be referred to as a cellular modem. A satellite communication module may also be referred to as a satellite modem or include a satellite modem. In some implementations, the cellular modem and the satellite modem are two separate devices. In some implementations, the cellular modem and the satellite modem may be integrated into a single device.

[0156] LBS modules can be used to obtain location information of electronic devices through the radio communication networks of telecommunications mobile operators or external positioning methods. Radio communication networks can include Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA). External positioning methods can include GNSS positioning.

[0157] In some embodiments, antenna 1 of electronic device 200 is coupled to mobile communication module 250, and antenna 2 is coupled to wireless communication module 260, enabling electronic device 200 to communicate with networks and other devices via wireless communication technology. Wireless communication technologies may include GSM, General Packet Radio Service (GPRS), CDMA, Wideband Code Division Multiple Access (WCDMA), Time-Division Code Division Multiple Access (TD-SCDMA), Long Term Evolution (LTE), BT, GNSS, WLAN, NFC, FM, and / or IR technologies, etc.

[0158] GNSS can include the Global Positioning System (GPS), the Global Navigation Satellite System (GLONASS), the BeiDou Navigation Satellite System (BDS), the Tiantong-1 Satellite Mobile Communication System, the Quasi-Zenith Satellite System (QZSS), and / or satellite-based augmentation systems (SBAS).

[0159] Electronic device 200 implements display functions through GPU, display screen 294, and application processor.

[0160] Internal memory 121 can be used to store executable program code, including instructions. Internal memory 121 may include a program storage area and a data storage area. The program storage area may store the operating system, at least one application program required for a function (such as sound playback, image playback, etc.), etc. The data storage area may store data created during the use of electronic device 200 (such as audio data, phonebook, etc.). Furthermore, internal memory 121 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, universal flash storage (UFS), etc. Processor 210 executes various functional applications and data processing of electronic device 200 by running instructions stored in internal memory 121 and / or instructions stored in memory located within the processor.

[0161] The software system of electronic device 200 can adopt a layered architecture, event-driven architecture, microkernel architecture, microservice architecture, or cloud architecture. This embodiment of the invention uses the layered architecture Android system as an example to exemplify the software structure of electronic device 200.

[0162] Figure 3 This is a block diagram related to the software architecture of the electronic device 200 according to an embodiment of the present invention.

[0163] A layered architecture divides software into several layers, each with a clear role and function. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom: the application layer, the application framework layer, the Android runtime and system libraries, and the kernel layer.

[0164] The application layer can include a series of application packages.

[0165] like Figure 3 As shown, the application package may include applications such as satellite, camera, decision center, calling, map, navigation, WLAN, Bluetooth, music, video, SMS, and display. The decision center is a newly added application in this embodiment.

[0166] The application framework layer provides application programming interfaces (APIs) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

[0167] like Figure 3 As shown, the application framework layer may include a window manager, content provider, view system, phone manager, resource manager, notification manager, etc.

[0168] The Android Runtime consists of core libraries and a virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

[0169] The core library consists of two parts: one part is the functionalities that need to be called by the Java language, and the other part is the Android core library.

[0170] The application layer and application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and application framework layer as binary files. The virtual machine is used to perform functions such as object lifecycle management, stack management, thread management, security and exception management, and garbage collection.

[0171] System libraries can include multiple functional modules. For example: surface manager, media libraries, 3D graphics processing libraries (e.g., OpenGL ES), 2D graphics engines (e.g., SGL), etc.

[0172] The kernel layer is the layer between hardware and software. The kernel layer contains at least the display driver, camera driver, audio driver, and sensor driver.

[0173] The hardware layer can include a modem, satellite communication module, LBS module, Wi-Fi, BitTorrent (BT), NFC, and IR. When the electronic device is in a cellular network coverage area, it can turn on the modem to search for and connect to the cellular network. When the electronic device is in an area without cellular network coverage or with poor cellular signal quality, it can turn on the satellite communication module to connect to the satellite network and turn off the modem, Wi-Fi, BT, NFC, and IR to reduce interference from other signal transmissions and receptions on satellite signal transmission and reception, thereby improving the quality of satellite signal transmission and reception. In some implementations, the LBS module of the electronic device is enabled by default and will only be disabled when the user manually disables the location service. Since the electronic device needs to perform satellite communication with satellites, which requires the device's location information, the LBS module is kept enabled when the device connects to the satellite network. In some implementations, the LBS module may remain enabled when the electronic device disconnects from the satellite network.

[0174] The following example illustrates the workflow of the software and hardware of electronic device 200, using the scenario of shutting down the satellite communication module as an example.

[0175] The electronic device displays the interface of the settings application, which includes a satellite switch control. When the touch sensor 280K receives a touch operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into a raw input event (including touch coordinates, timestamp of the touch operation, etc.). The raw input event is stored in the kernel layer. The application framework layer retrieves the raw input event from the kernel layer and identifies the control corresponding to the input event. Taking a single touch operation as an example, where the corresponding control is the satellite switch control in the settings application, the settings application calls the interface of the application framework layer to launch the settings application, and then calls the kernel layer to disable the satellite communication module.

[0176] In this embodiment of the application, the control method provided by the present application is described using the signal transceiver modules associated with flight mode as Modem, Wi-Fi, BT, NFC and IR, and the Modem, Wi-Fi, BT, NFC and IR are all turned on before flight mode is turned on.

[0177] Figure 4 A flowchart of a control method provided in an embodiment of this application is shown.

[0178] like Figure 4 As shown, the method may include:

[0179] After S400 electronic devices are connected to the satellite network, users can use their electronic devices for satellite communication. Satellite communication services can include satellite calls, sending and receiving satellite text messages, satellite video communication, or satellite voice communication within the satellite network.

[0180] For example, a user can touch the display screen of an electronic device to open the Settings app. On the Settings app interface displayed on the electronic device, the user can touch the satellite switch control. The kernel layer generates and stores touch events. Touch events include touch coordinates and a timestamp of the touch operation. The application framework layer obtains the touch events from the kernel layer. The application framework layer identifies the touch event as the satellite switch control on the Settings app interface. The application framework layer transmits information about the satellite switch control being touched to the Settings app. The Settings app maintains the satellite communication module's status flag as an enabled flag (or tripped flag), thus enabling the satellite communication module. The satellite communication module searches for and connects to satellite networks, allowing the electronic device to access the satellite network.

[0181] Once an electronic device is connected to a satellite network, the user can use the device to communicate with another electronic device or a rescue platform via satellite.

[0182] S401, The decision center determines whether the electronic equipment has disconnected from the satellite network.

[0183] For example, after satellite communication ends, a user can touch the screen of an electronic device to open the settings application. On the settings application interface displayed on the electronic device, the user can touch the satellite switch control. The kernel layer generates and stores the touch event. The application framework layer obtains the touch event from the kernel layer. The application framework layer identifies the control corresponding to the touch event as the satellite switch control on the settings application interface. The application framework layer transmits information about the satellite switch control being touched to the settings application. The settings application maintains the status flag of the satellite communication module as a closed (or disabled) flag, thus enabling the settings application to close the satellite communication module, causing the electronic device to disconnect from the satellite network. Disconnecting the electronic device from the satellite network can be understood as the electronic device exiting satellite mode.

[0184] When the application maintains the status flags of the satellite communication module, it can transmit information indicating changes in the module's status to the decision center. The decision center then reads the status flags of the satellite communication module.

[0185] If a shutdown flag (or disable flag) is read, the decision center determines that the electronic device is disconnected from the satellite network, and the decision center can execute step S402.

[0186] If an enable flag (or tripod flag) is read, the decision center determines that the electronic device has not disconnected from the satellite network, and the decision center may not take any action.

[0187] Optionally, the decision center can register a first fence with the application framework layer. The first fence is triggered when the application maintains the status flags of the satellite communication module. The application framework layer sends a message to the decision center indicating that the first fence has been triggered. The decision center then reads the status flags of the satellite communication module.

[0188] Optionally, the decision center can also register a second fence with the application framework layer. The second fence is triggered when the satellite communication service is triggered. The application framework layer transmits a message indicating that the second fence has been triggered to the decision center. If the decision center receives a message indicating that the first fence has been triggered, it determines whether the previously received fence-triggered message is the same as the message indicating that the second fence has been triggered. If so, the decision center reads the status flag of the satellite communication module. If not, the decision center can obtain the most recently stored location information of the electronic device to determine whether the area where the electronic device is located has no cellular network coverage. If it is determined that the area where the electronic device is located has no cellular network coverage, the decision center reads the status flag of the satellite communication module. If it is determined that the area where the electronic device is located has cellular network coverage, the decision center does not perform any processing. The specific implementation of the decision center obtaining the most recently stored location information of the electronic device to determine whether the area where the electronic device is located has no cellular network coverage can be found in subsequent step S407.

[0189] Similarly, if the decision center receives a message from the settings application indicating a change in the satellite communication module's status, it can determine whether the most recently received fence-triggered message is a second fence-triggered message. If so, the decision center reads the satellite communication module's status flag. If not, the decision center can obtain the electronic device's most recently stored location information to determine whether the area where the electronic device is located has no cellular network coverage. If it is determined that the area where the electronic device is located has no cellular network coverage, the decision center reads the satellite communication module's status flag. If it is determined that the area where the electronic device is located has cellular network coverage, the decision center takes no action.

[0190] If the decision center determines that the most recently received fence trigger message is a second fence trigger message, and the decision center reads a shutdown flag (or disable flag), it indicates that the user's operation to shut down the satellite communication module corresponds to a power-saving intention. The electronic device can display a pop-up window prompting the user to perform further power-saving mode operations. Optionally, if the decision center determines that the most recently received fence trigger message is a second fence trigger message, and the decision center reads a shutdown flag (or disable flag), the electronic device can also directly execute step S404.

[0191] If the decision center determines that the most recently received fence trigger message is not a second fence trigger message, and determines that the area where the electronic device is located has no cellular network coverage, and the decision center reads the off flag (or disabled flag), it indicates that the user's operation of turning off the satellite communication module corresponds to a power-saving intention. The electronic device can display a pop-up window prompting the user to perform further power-saving mode operations. Optionally, if the decision center determines that the most recently received fence trigger message is a second fence trigger message, and the decision center reads the off flag (or disabled flag), the electronic device can also directly execute step S404.

[0192] If the decision center determines that the most recently received fence-triggered message is not the second fence-triggered message, and determines that the area where the electronic device is located is covered by a cellular network, and the decision center reads the off flag (or disabled flag), it means that the user's operation of turning off the satellite communication module is not intended to save power. The decision center can then leave it alone, so that after the electronic device disconnects from the satellite network, the Modem, Wi-Fi, BT, NFC, and IR can return to their state before airplane mode or remain on, so that the user can use the functions of the Modem, Wi-Fi, BT, NFC, and IR in a timely manner.

[0193] S402, The decision center determines whether the operation on the electronic device is an operation to enter the ultra-long standby mode.

[0194] When an electronic device disconnects from the satellite network, it exits flight mode. The modem, Wi-Fi, Bluetooth, NFC, and IR functions on the device are all active, potentially increasing power consumption. Therefore, the device may prompt the user to enter extended standby mode to conserve battery power while awaiting rescue.

[0195] For example, when the decision center determines that an electronic device has disconnected from the satellite network, it can pass a view of a second pop-up window to the application framework layer, causing the electronic device to display the second pop-up window. The second pop-up window may include confirmation controls, cancellation controls, and a prompt to enter extended standby mode. Displaying the second pop-up window prompts the user to enter extended standby mode. Scenarios of the electronic device displaying the second pop-up window can be found in subsequent sections. Figure 5 As shown, for ease of understanding, Figure 5 The scenario where the electronic device displays the second pop-up window will be explained later.

[0196] On the second pop-up window displayed on the electronic device, the user can touch the screen. When the user touches the screen, the decision center receives the touch event. The decision center identifies whether the control corresponding to the touch location of the touch event is the confirmation control of the second pop-up window.

[0197] If so, the decision center determines that the user's operation on the electronic device is to enter the ultra-long standby mode, and the electronic device can proceed to step S403. If not, the decision center determines that the user's operation on the electronic device is not to enter the ultra-long standby mode, and the electronic device can proceed to step S406.

[0198] Optionally, when the decision center passes the view of the second pop-up to the application framework layer, the decision center can set a second timer. The duration of the second timer is a second timeout period. When the second timer reaches the second timeout period, if the decision center does not receive a touch event, the decision center can default to not entering the ultra-long standby mode, and the electronic device can execute step S406.

[0199] Optionally, when the decision center passes the view of the second pop-up to the application framework layer, the decision center can set a second timer. When the second timer reaches the second timeout duration, if the decision center does not receive a touch event, the decision center can default to entering an ultra-long standby mode, and the electronic device can execute step S403.

[0200] S403, The decision center determines whether the operation on the electronic device is an operation to turn off the modem.

[0201] For example, if the decision center determines that the user's operation on the electronic device is to enter an ultra-long standby mode, the decision center passes the view of the first pop-up window to the application framework layer so that the electronic device displays the first pop-up window. The first pop-up window may include a confirmation control, a cancellation control, and a prompt to turn off the modem. Displaying the first pop-up window on the electronic device can prompt the user to turn off the modem. Scenarios of the electronic device displaying the first pop-up window can be found in subsequent sections. Figure 5 As shown, for ease of understanding, Figure 5 The scenario of the electronic device displaying the first pop-up window will be explained later.

[0202] On the first pop-up window displayed on the electronic device, the user can touch the screen. When the user touches the screen, the decision center receives the touch event. The decision center determines whether the control corresponding to the touch location is the confirmation control of the first pop-up window.

[0203] If so, the decision center determines that the user's operation on the electronic device is to turn off the modem, and the electronic device can execute step S404.

[0204] If not, the decision center determines that the user's operation on the electronic device is not an operation to turn off the modem, and the electronic device can proceed to step S405.

[0205] Optionally, when the decision center passes the view of the first pop-up to the application framework layer, the decision center can set a first timer. The duration of the first timer is a first timeout period. When the first timer reaches the first timeout period, if the decision center does not receive a touch event, the decision center can default to not turning off the modem, and the electronic device can execute step S405. The first timeout period and the second timeout period can be the same or different.

[0206] Optionally, when the decision center passes the view of the first pop-up to the application framework layer, the decision center can set a first timer. When the first timer reaches the first timeout duration, if the decision center does not receive a touch event, the decision center can turn off the modem by default, and the electronic device can execute step S404.

[0207] S404, the Decision Center instructs the settings app to turn off Modem, Wi-Fi, BT, NFC, and IR, and also instructs the settings app to adjust the display brightness to a preset brightness.

[0208] For example, if the decision center determines in step S403 that the user's operation on the electronic device is to turn off the modem, the decision center instructs the settings application to turn off the modem, Wi-Fi, BT, NFC, and IR, and also instructs the settings application to adjust the display brightness to a preset brightness. This reduces the power consumption of the electronic device.

[0209] A preset brightness level is the brightness value that consumes the least power without affecting user experience. Adjusting the display brightness to the preset level can reduce the power consumption of electronic device displays.

[0210] Understandably, if the modules associated with flight mode include other configurable modules, and these other configurable modules are enabled before flight mode is activated, the decision center can instruct the settings application to disable these other configurable modules if it is determined in step S403 that the user's operation on the electronic device is to turn off the modem. These other configurable modules can be signal transceiver modules. They may also not be signal transceiver modules, such as processing modules.

[0211] Optionally, if it is determined in step S403 that the user's operation on the electronic device is to turn off the modem, the decision center may also instruct the settings application display to lower the refresh rate to reduce the power consumption of the electronic device display.

[0212] Optionally, if the decision center determines in step S403 that the user's operation on the electronic device is to enter airplane mode, the decision center can instruct the settings application to control the modem to a low-power state and turn off Wi-Fi, BT, NFC, and IR. It can also instruct the settings application to adjust the display brightness to a preset brightness to reduce the power consumption of the electronic device. The modem being in a low-power state can mean that the modem is not powered off but is not searching for a network. Turning off Wi-Fi can mean that Wi-Fi is powered off.

[0213] S405. If the decision center determines that the user's operation on the electronic device is not an operation to turn off the modem, the decision center instructs the settings application to turn off Wi-Fi, BT, NFC and IR, and also instructs the settings application to adjust the display brightness to the preset brightness.

[0214] For example, in step S403, if the decision center determines that the control corresponding to the touch position of the touch event is the cancel control of the first pop-up window, or if the decision center does not receive a touch event when the first timer reaches the first timeout duration, it can indicate that the user's intention is to perform cellular network search in ultra-long standby mode. The decision center determines not to turn off the modem. The decision center can instruct the settings application to turn off Wi-Fi, BT, NFC and IR, and also instruct the settings application to adjust the screen brightness to the preset brightness to reduce the power consumption of the electronic device. The modem can then perform network search in step S406.

[0215] S406, the Modem searches for networks according to the first periodic network search method.

[0216] For example, if the decision center determines in step S402 that the user's operation on the electronic device is not an operation to enter the ultra-long standby mode, the decision center can instruct the modem to search for a network according to the first periodic network search method.

[0217] Alternatively, after the decision center instructs the settings application to turn off Wi-Fi, BT, NFC, and IR in step S405 and adjusts the display brightness to the preset brightness, the decision center can instruct the modem to search for a network according to the first periodic network search method.

[0218] In the first periodic network search mode, the network search interval increases sequentially. By increasing the network search interval, the power consumption of the modem during network search can be reduced.

[0219] Optionally, when the search interval of the first periodic network search method increases to a first search interval threshold, the search interval of the first periodic network search method will no longer increase. This can reduce the probability of failing to find a cellular network.

[0220] The first periodic search method can be found in subsequent articles. Figure 6 The periodic net-searching method shown is for ease of understanding. Figure 6 The periodic net-searching method shown will be explained in detail later.

[0221] Optionally, the decision center can also register a third fence with the application framework layer. The third fence is triggered when a cellular communication service is activated. The application framework layer then sends a message to the decision center indicating that the third fence has been activated. A cellular communication service can characterize a service that requires communication using a cellular network.

[0222] During the modem's network search using the first periodic search method, if the decision center receives a message indicating that the third fence has been triggered, the decision center can determine whether the modem's network search interval exceeds the third network search interval threshold. If it does, the decision center instructs the modem to search using the second periodic search method. If it does not exceed the threshold, the decision center can take no action.

[0223] In this method, the third network search interval threshold can be the same as or different from the minimum network search interval of the first periodic network search method. The network search interval of the second periodic network search method increases sequentially, and within the same period, the network search interval of the second periodic network search method is smaller than that of the first periodic network search method. This facilitates the electronic device in quickly finding the cellular network. Similarly, when the network search interval of the second periodic network search method increases to the second network search interval threshold, the network search interval of the second periodic network search method no longer increases, thus reducing the probability of failing to find a cellular network.

[0224] Understandably, the activation of cellular communication services indicates that the user urgently needs to use the communication network. The decision center instructs the modem to search for a network using the second periodic network search method so that the electronic device can find the cellular network as quickly as possible. By registering a third fence, the decision center can identify scenarios where the user urgently needs to use the communication network.

[0225] When the decision center receives a message from a user initiating a service, it indicates that the user needs to communicate. If the modem's network search interval exceeds the third network search interval threshold, it means that the modem's network search interval is too long, and there may be situations where it cannot find a cellular network in time. Therefore, when the decision center determines that the modem's network search interval exceeds the third network search interval threshold, it instructs the modem to search for networks using the second periodic network search method. This can shorten the network search interval, enable timely searches for cellular networks, and thus improve the user experience.

[0226] During the process of the modem searching for a network in the first periodic network search method, the electronic device can also execute step S407.

[0227] S407. The Location-Based Services (LBS) module determines whether an electronic device is located in an area without cellular network coverage.

[0228] For example, if the LBS module is enabled, it can obtain the location information of the electronic device in real time or periodically. The location information can be latitude and longitude. The location information can also be referred to as LBS location.

[0229] The LBS module can use location information and a pre-stored search map to determine whether the location information is within a preset geofence on the search map. Areas within the preset geofence have no cellular network coverage or poor cellular signal strength. Electronic devices cannot access the cellular network. Preset geofences include, for example, geofences for ocean areas or desert areas. For instance, the LBS module can use a geofence algorithm to calculate the location information and the preset geofence to determine whether the location information is within the preset geofence.

[0230] If the LBS module determines that the location information is within the preset geofence, the LBS module can transmit the positive result to the decision center, and the decision center can execute step S408.

[0231] If the LBS module determines that the location information is not within the preset geofence, the LBS module can transmit a negative result to the decision center. The decision center can then leave it as is, allowing the electronic device to continue executing step S406.

[0232] For example, the pre-stored network map can be built into the system of the electronic device at the factory, or it can be obtained by the electronic device from a communication electronic map database in a cloud server. For example, the communication electronic map database in the cloud server can be obtained by organizing and drawing raw data collected by the cloud server from network crowdsourcing. The communication electronic map database can be updated periodically. When the communication electronic map database is updated, the cloud server can broadcast it to its subordinate electronic devices via a cloud service API. When the electronic device receives the broadcast, its decision center can obtain the network map from the communication electronic map database in the cloud server.

[0233] For example, the search map may also include a correspondence between search method identifiers and geofence identifiers. The search method identifiers may include a second periodic search method identifier and a first periodic search method identifier. Geofence identifiers for land areas with high cellular signal strength may correspond to the second periodic search method identifier, while geofence identifiers for land areas with poor cellular signal strength may correspond to the first periodic search method identifier.

[0234] If the LBS module determines that the location information is not within the preset geofence, it can identify the geofence marker where the location information is located and thus obtain the geofence search method identifier. The LBS module can then transmit this geofence search method identifier to the decision center. The decision center can then instruct the modem to search the geofence according to the geofence search method identifier transmitted by the LBS module.

[0235] In this way, when the electronic device is in an area with high cellular signal strength, the modem can perform a network search using the second periodic search method to promptly find and access the cellular network. When the electronic device is in an area with low cellular signal strength, the modem can perform a network search using the first periodic search method to reduce network search power consumption.

[0236] For example, the network search map may also include the correspondence between cellular signal quality information and geofence identifiers. If the LBS module determines that the location information is not within a preset geofence, the LBS module can identify the geofence identifier where the location information is located and transmit the network search method identifier and cellular signal quality information to the decision center. The decision center uses a self-learning method to perform cell quality assessment in order to match the network search strategy with the location information to determine whether the network search method or strategy matches the location information. The decision center instructs the modem to perform a network search according to the network search method or strategy that matches the location information.

[0237] For example, when an electronic device disconnects from the satellite network, if the electronic device controls the LBS module to be in a closed state, the decision center can obtain the most recently stored location information from the LBS module because the electronic device needs to perform satellite communication and requires location information. When the decision center determines that the electronic device is in a slightly moving or stationary state, it can determine whether the most recently stored location information from the LBS module is within a preset geofence. If yes, the decision center can execute step S408. If not, the decision center does not perform any action.

[0238] S408, The decision center instructs the modem to stop searching for networks.

[0239] For example, if the decision center determines that the location information is within a preset geofence, the decision center can instruct the settings app to turn off the modem to stop the search for cellular networks.

[0240] If the electronic device is within a preset geofence, the modem's network search is considered invalid, and the decision center can instruct the modem to stop searching. This reduces the power consumption of invalid network searches.

[0241] The control method provided in this embodiment, when the electronic device exits satellite mode, displays a second pop-up window prompting the user to enter an ultra-long standby mode. In response to not entering ultra-long standby mode, the electronic device searches for a network using a first periodic network search method. By increasing the network search interval, network search power consumption can be reduced, thus preserving a longer battery life for the user while waiting for rescue. Alternatively, in response to entering ultra-long standby mode, the electronic device can also display a first pop-up window prompting the user to turn off the modem. In response to the user turning off the modem, the electronic device shuts down the modem, Wi-Fi, BitTorrent, NFC, and IR, reducing the power consumption of these components, thereby reducing the overall power consumption of the electronic device and preserving a longer battery life for the user while waiting for rescue. The electronic device can also respond to the user's operation of canceling the modem's shutdown. The electronic device turns off Wi-Fi, BT, NFC, and IR, and instructs the modem to search for a network according to the first periodic network search method. In the scenario where the electronic device searches for a network, the power consumption of Wi-Fi, BT, NFC, and IR is reduced, thereby reducing the power consumption of the electronic device and preserving a longer battery life for waiting for rescue.

[0242] To facilitate the following Figure 4 The control method provided in the illustrated embodiment will be understood in the following sections. Figure 5 and Figure 6 The illustrated embodiment will be used for explanation.

[0243] Figure 5 This image shows a scenario where a pop-up window appears on an electronic device.

[0244] like Figure 5 As shown, when electronic devices connect to a satellite network, the electronic devices can display... Figure 5 The interface shown in 'a'. For example... Figure 5 The interface shown in 'a' includes icon 101.

[0245] exist Figure 5 On the interface shown in Figure 'a', users can perform a pull-down operation from the top of the electronic device or a pull-up operation from the bottom of the electronic device. The electronic device can then display something like... Figure 5 The control center interface shown in 'i'. Figure 5 See the content of the interface shown by 'i' in the image. Figure 1 The content of the interface shown in b is not described here. Figure 5 The brightness status shown by control 108 in the interface indicated by 'i' represents the brightness status of the display screen when the electronic device is connected to the satellite network.

[0246] exist Figure 5On the interface shown as 'a', users can perform touch operations to turn off the satellite communication module, thus disconnecting the electronic device from the satellite network. When the electronic device disconnects from the satellite network, it can display... Figure 5 The interface shown in b. Figure 5 The interface shown in b includes a second pop-up window 501, icons 109, 110, and 111. Icon 101 has disappeared from this interface. The second pop-up window 501 includes the text "Enter ultra-long standby mode?", a confirmation control 5011, and a cancellation control 5012.

[0247] exist Figure 5 On the interface shown in b, the user can click the confirmation control 5011. The electronic device can display... Figure 5 The interface shown in c is or Figure 5 The interface shown in f is shown in the image. Figure 5 The content of the interface shown in c is the same as Figure 5 The content of the interface shown in f is the same. Figure 5 The interface shown in c is the same as Figure 5 The difference in the interface shown by 'f' lies in the different user operations.

[0248] like Figure 5 The interface shown in c includes a first pop-up window 502, icons 109, 110, and 111. The first pop-up window 502 includes the text "Turn off Modem?", a confirmation control 5021, and a cancellation control 5022.

[0249] In one possible scenario, if the user is in an area with no cellular network coverage and is not moving, then... Figure 5 On the interface shown as 'c', the user can click the confirmation control 5021. The electronic device can display... Figure 5 The interface shown by d in the figure. Figure 5 The interface shown in 'd' has disappeared, with the first pop-up 502, icon 109, icon 110, and icon 111 all gone. The user has not moved the device; for example, the electronic device is either slightly moving or stationary.

[0250] exist Figure 5 On the interface shown as 'd', users can perform a pull-down operation from the top of the electronic device or a pull-up operation from the bottom of the electronic device, and the electronic device can display... Figure 5 The interface shown by 'e' in the diagram. Figure 5The interface shown in 'e' includes non-highlighted controls 102, 103, 104, 105, 106, 107, and 108. The brightness state shown by control 108 can indicate the brightness state of the display screen when the electronic device enters an ultra-long standby mode.

[0251] from Figure 5 As can be seen from 'i' and 'a', when an electronic device connects to a satellite network, the satellite communication module is in the on state, while the Modem, Wi-Fi, BT, NFC, and IR are all in the off state, reducing the power consumption of the Modem, Wi-Fi, BT, NFC, and IR.

[0252] from Figure 5 As shown in b, c, d, and e, when a user is in an area without cellular network coverage and is not moving, and the electronic device disconnects from the satellite network, enters ultra-long standby mode, and the modem is turned off, the satellite communication module is also off, as are the modem, Wi-Fi, Bluetooth, NFC, and IR. This reduces the power consumption of the satellite communication module, modem, Wi-Fi, Bluetooth, NFC, and IR. Compared to the power consumption when the electronic device is connected to the satellite network, the power consumption after disconnecting from the satellite network is even lower, which helps preserve the device's battery life.

[0253] from Figure 5 As indicated by 'i' and 'e', ​​the screen brightness is high when the electronic device is connected to a satellite network. When the electronic device disconnects from the satellite network, enters ultra-long standby mode, and the modem is turned off, the screen brightness decreases. This reduces the screen's power consumption.

[0254] Therefore, when an electronic device disconnects from the satellite network, enters an ultra-long standby mode, and turns off the modem, the control method provided in this embodiment can enable the electronic device to retain a longer battery life while waiting for rescue.

[0255] In another possible scenario, the user is in an area without cellular network coverage and is moving. Figure 5 On the interface shown in the image, the user can click the cancel control 5022, and the electronic device can display... Figure 5 The interface shown in g is shown in the image. Figure 5 See the content of the interface shown in 'g'. Figure 5 The content of the interface shown as 'd' in the diagram will not be elaborated upon here. User movement indicates that the electronic device is neither in a state of slight movement nor in a state of stillness.

[0256] exist Figure 5On the interface shown by 'g', users can perform a pull-down operation from the top of the electronic device or a pull-up operation from the bottom of the electronic device, and the electronic device can display... Figure 5 The interface shown by 'h' in the diagram. Figure 5 The interface shown in h includes non-highlighted controls 102, 103, 104, 105, 106, 107, and 108. Figure 5 The brightness status shown by control 108 in the interface indicated by h also represents the brightness status of the display screen when the electronic device enters the ultra-long standby mode. Figure 5 The brightness status shown by control 108 in the interface shown by h is related to... Figure 5 The brightness state of control 108 in the interface shown in Figure e is the same. Figure 5 The interface shown in h is the same as Figure 5 The difference between the interface shown in 'e' and the interface shown in 'e' is that, in Figure 5 In the interface shown in 'e', ​​control 105 is not highlighted, while... Figure 5 Control 105 is highlighted on the interface shown by h.

[0257] Control 105 is highlighted to indicate that the modem is on and can perform cellular network searches. This allows the electronic device to continue searching for cellular networks even when the user is in an area without cellular coverage and is moving, so that the user can connect to the cellular network promptly when they move to an area with coverage.

[0258] from Figure 5 As shown by b, f, g, and h, when a user is in an area without cellular network coverage and is moving, when the electronic device disconnects from the satellite network and enters an ultra-long standby mode, the modem remains on while the satellite communication module, Wi-Fi, BitTorrent, NFC, and IR are also off. This allows the modem to search for cellular networks so that when the user moves to an area with cellular network coverage, they can promptly connect to the cellular network and establish real-time contact with rescuers. The fact that the satellite communication module, Wi-Fi, BitTorrent, NFC, and IR are all off reduces the power consumption of these components.

[0259] from Figure 5 As indicated by 'i' and 'h', the screen brightness is high when the electronic device is connected to the satellite network. When the electronic device disconnects from the satellite network and enters ultra-long standby mode without turning off the modem, the screen brightness decreases. This reduces the screen's power consumption.

[0260] Therefore, when an electronic device disconnects from the satellite network and enters an ultra-long standby mode without turning off the modem, the control method provided in this embodiment can also enable the electronic device to retain a longer battery life while waiting for rescue.

[0261] Figure 6 A schematic diagram of the periodic network search method provided in an embodiment of this application is shown.

[0262] In one possible implementation, if the user is within cellular network coverage, the modem can perform a network search using the second periodic search method. If the user initiates a cellular communication service, the modem can perform a network search using the first periodic search method. Both the second and first periodic search methods belong to the OOS (Out of Service) network search mechanism. The difference between the second and first periodic search methods is that, within the same search cycle, the search interval of the first periodic search method is longer than that of the second periodic search method.

[0263] For example, such as Figure 6 As shown, in both the second and first periodic net-searching methods, the net-searching duration for each cycle is t. s The search interval (or sleep duration) for the second periodic search method is t. x，1 t x，2 t x，3 、…、t x，m-1 t x，m The search interval (or sleep duration) for the first periodic search method is t. x，m+1 t x，m+2 t x，m+3 、…、t x，m+n-1 t x，m+n .

[0264] Among them, t x，1 <t x，2 <t x，3 <t x，m-1 <t x，m . t x，m+1 <t x，m+2 <t x，m+3 <t x，m+n-1 <t x，m+n And t x，1 <t x，m+1 . t x，2 <t x，m+2 . t x，3 <t x，m+3 . t x，m-1 <t x，m+n-1 . t x，m <t x，m+n . t x，m This is the second search interval threshold.x，m+n This is the first search interval threshold. Optionally, t x，m <t x，m+1 . t x，m+1 This is the minimum search interval for the first periodic search method.

[0265] For example, to facilitate understanding of whether the modem searches for a network using the second periodic network search method or the first periodic network search method, the following explanation uses the modem searching for a network using the first periodic network search method as an example:

[0266] The modem starts a third timer when it begins searching for a network. The duration of the third timer is t. s .

[0267] When the third timer reaches its timing duration t s If the modem fails to find a network, it will go to sleep (or stop searching for a network) and set a fourth timer. The duration of the fourth timer is t. x，m+1 .

[0268] When the fourth timer reaches its timing duration t x，m+1 At that time, the modem starts searching for the network, cancels the fourth timer, and starts the third timer.

[0269] When the third timer reaches duration t s If the modem fails to find a network, it will go to sleep and set a fifth timer. The duration of the fifth timer is t. x，m+2 .

[0270] When the fifth timer reaches its timing duration t x，m+2 At that time, the modem starts searching for the network, cancels the fifth timer, and starts the third timer.

[0271] When the third timer reaches its timing duration t s If the modem fails to find a network, it will go to sleep and set a sixth timer. The duration of the sixth timer is t. x，m+3 .

[0272] When the sixth timer reaches its timing duration t x，m+3 At that time, the modem begins searching for the network, cancels the sixth timer, and starts the third timer.

[0273] This cycle repeats, searching the network and then going into hibernation.

[0274] It is understandable that when the third timer reaches the timing duration t... s Previously, or when the third timer reaches the set duration t s If the modem successfully finds a network, it will stop searching for networks.

[0275] The maximum search interval for the first periodic network search method is the first search interval threshold. The maximum search interval for the second periodic network search method is the second search interval threshold. During the network search process using either the first or second periodic method, if no network is found in the previous search cycle, the search interval will be increased in the next search cycle. This reduces the power consumption of the modem during network search. The minimum search interval for the first periodic network search method is greater than the maximum search interval for the second periodic network search method. This further reduces the power consumption of the modem during network search when the electronic device is in an environment with no cellular network coverage or low cellular signal strength, preserving a longer battery life for the electronic device while awaiting assistance.

[0276] This embodiment also provides a control method. Figure 7 Another flowchart of the control method provided in the embodiments of this application is shown. Figure 7 The illustrated embodiments and Figure 4 The difference in the illustrated embodiment is that, Figure 7 The illustrated embodiments do not include Figure 4 Steps S402, S403, and S405 in the illustrated embodiment, Figure 7 The illustrated embodiment includes step S701. Figure 7 The illustrated embodiments also include Figure 4 Steps S400, S401, S404, S406, S407, and S408 in the illustrated embodiment. Figure 7 For the specific implementation principles and technical effects of steps S400, S401, S404, S406, S407, and S408 in the illustrated embodiment, please refer to [link / reference needed]. Figure 4 The specific implementation principles and technical effects of the corresponding steps in the illustrated embodiments will not be repeated in this embodiment.

[0277] like Figure 7 As shown, the method includes:

[0278] After S400 electronic devices are connected to the satellite network, users can use their electronic devices for satellite communication.

[0279] S401, The decision center determines whether the electronic equipment has disconnected from the satellite network.

[0280] S701, the decision center determines whether the operation of the electronic device is an operation to enter flight mode.

[0281] When an electronic device disconnects from the satellite network, it exits flight mode. Since the modem, Wi-Fi, Bluetooth, NFC, and IR functions on the electronic device are active, power consumption may increase. Therefore, the electronic device may prompt the user to enter flight mode to preserve longer battery life for rescue purposes.

[0282] For example, when the decision center determines that an electronic device has disconnected from the satellite network, it can pass a view of a third pop-up window to the application framework layer, causing the electronic device to display the third pop-up window. The third pop-up window may include confirmation and cancellation controls. Displaying the third pop-up window can prompt the user to enter airplane mode. See [link to relevant scenario] for an example of an electronic device displaying a third pop-up window. Figure 8 The embodiments shown are for ease of understanding. Figure 8 The implementation shown will be explained later.

[0283] On the third pop-up window displayed on the electronic device, the user can touch the screen. When the user touches the screen, the decision center receives the touch event. The decision center identifies whether the control corresponding to the touch location of the touch event is the confirmation control of the third pop-up window.

[0284] If so, the decision center determines that the user's operation on the electronic device is to enter airplane mode, and the electronic device can proceed to step S404. If not, the decision center determines that the user's operation on the electronic device is not to enter airplane mode, and the electronic device can proceed to step S406.

[0285] Optionally, when the decision center passes the view of the third pop-up to the application framework layer, the decision center can set a seventh timer. The duration of the seventh timer is the seventh timeout period. When the seventh timer reaches the seventh timeout period, if the decision center does not receive a touch event, the decision center can default to not entering airplane mode, and the electronic device can execute step S406.

[0286] S404, the Decision Center instructs the settings app to turn off Modem, Wi-Fi, BT, NFC, and IR, and also instructs the settings app to adjust the display brightness to a preset brightness.

[0287] For example, if the decision center determines in step S701 that the user's operation on the electronic device is to enter airplane mode, the decision center instructs the settings application to turn off the modem, Wi-Fi, BT, NFC and IR, and also instructs the settings application to adjust the display brightness to a preset brightness in order to reduce the power consumption of the electronic device.

[0288] S406, the Modem searches for networks according to the first periodic network search method.

[0289] S407. The Location-Based Services (LBS) module determines whether an electronic device is located in an area without cellular network coverage.

[0290] S408, The decision center instructs the modem to stop searching for networks.

[0291] For example, Figure 8 This shows another scenario where an electronic device displays a pop-up window.

[0292] like Figure 8 As shown, when electronic devices connect to a satellite network, the electronic devices can display... Figure 8 The interface shown in 'a'. Figure 8 The content of the interface shown in 'a' can be found in [reference]. Figure 5 The content of the interface shown in 'a' will not be described again here.

[0293] exist Figure 8 On the interface shown in Figure 'a', users can perform a pull-down operation from the top of the electronic device or a pull-up operation from the bottom of the electronic device. The electronic device can then display something like... Figure 8 The control center interface shown in 'e' is shown in the image. Figure 8 The content of the interface shown in 'e' can be found in [reference]. Figure 5 The content of the interface shown by 'i' in the figure will not be described again here.

[0294] exist Figure 8 On the interface shown as 'a', users can perform touch operations to turn off the satellite communication module, thus disconnecting the electronic device from the satellite network. When the electronic device disconnects from the satellite network, it can display... Figure 8 The interface shown in b. Figure 8 The interface shown in b includes a third pop-up window 801, icons 109, 110, and 111. Icon 101 has disappeared from this interface. The third pop-up window 801 includes the text "Enter airplane mode?", a confirmation control 8011, and a cancellation control 8012.

[0295] exist Figure 8 On the interface shown in b, the user can click the confirmation control 8011. The electronic device can display... Figure 8 The interface shown in 'c'. For example... Figure 8 In the interface shown in c, the third pop-up window 801, icon 109, icon 110, and icon 111 have all disappeared.

[0296] exist Figure 8 On the interface shown in 'c', users can perform a pull-down operation from the top of the electronic device or a pull-up operation from the bottom of the electronic device, and the electronic device can display... Figure 8 The interface shown by d in the figure. Figure 8The interface shown as d includes non-highlighted controls 102, 103, 104, 105, 106, 107, and 108. The brightness state shown by control 108 can indicate the brightness state of the display screen when the electronic device enters an ultra-long standby mode.

[0297] from Figure 8 As can be seen from d and e, when an electronic device enters airplane mode, the brightness of the display screen decreases, which reduces the power consumption of the display screen.

[0298] from Figure 8 As can be seen from 'a' and 'e', ​​when an electronic device connects to a satellite network, the satellite communication module is in the on state, while the Modem, Wi-Fi, BT, NFC, and IR are all in the off state, reducing the power consumption of the Modem, Wi-Fi, BT, NFC, and IR.

[0299] from Figure 8 As shown in b, c, and d, when the electronic device disconnects from the satellite network and enters flight mode, the satellite communication module is turned off, as are the modem, Wi-Fi, BT, NFC, and IR. This reduces the power consumption of the satellite communication module, modem, Wi-Fi, BT, NFC, and IR.

[0300] Therefore, when an electronic device disconnects from the satellite network and enters flight mode, the control method provided in this embodiment can enable the electronic device to retain a longer battery life while waiting for rescue.

[0301] The control method provided in this embodiment, when the electronic device exits satellite mode, displays a third pop-up window prompting the user to enter flight mode. In response to not entering flight mode, the electronic device searches for a network using a first periodic network search method. By increasing the network search interval, network search power consumption can be reduced, thus preserving a longer battery life for the user while waiting for rescue. The electronic device can also, in response to entering flight mode, turn off the modem, Wi-Fi, BT, NFC, and IR, reducing the power consumption of these components, thereby reducing the overall power consumption of the electronic device and preserving a longer battery life for the user while waiting for rescue. Compared to... Figure 4 As shown in the embodiment, the control method provided in this embodiment does not require multiple pop-up windows to prompt the user to perform power-saving operations, which can reduce the number of times the user operates the electronic device.

[0302] This application also provides a control method, which includes steps S901-S903.

[0303] S901. At the first moment, the electronic device receives an operation to turn off the satellite communication mode, and the electronic device disconnects from the satellite network.

[0304] The specific implementation method of this step and Figure 4 The specific implementation of S401 in the embodiment is similar, and will not be described again here.

[0305] S902, at the second moment, the electronic device displays a first pop-up window. The first pop-up window includes a first control and a first prompt message, which prompts whether to turn off cellular communication. The second moment is later than the first moment.

[0306] For example, the first pop-up window could be Figure 4 The first pop-up window in the embodiment may be, for example, Figure 5 The first pop-up window 502 in the embodiment. The first control can be... Figure 4 The confirmation control in the first pop-up window in the embodiment may be, for example, Figure 5 The confirmation control 5021 in the embodiment. The first prompt message may be... Figure 4 The first pop-up window in the embodiment includes a prompt message to turn off the modem, for example... Figure 5 The first pop-up window 502 in the embodiment contains the text "Do you want to turn off the Modem?".

[0307] For example, the first pop-up window could also be Figure 8 The third pop-up window 801 in the embodiment. The first control can also be Figure 8 The confirmation control 8011 in the embodiment. The first prompt message can also be... Figure 8 The third pop-up window 801 in the embodiment contains the text "Enter flight mode?".

[0308] S903, at the third moment, in response to the operation of the first control, the modem controlling the electronic device is turned off. The third moment is later than the second moment.

[0309] For example, a specific implementation of an electronic device controlling its modem to be in a switched-off state in response to an operation on a first control is similar to... Figure 4 The specific implementation of S404 in the embodiment is similar, and will not be described again here.

[0310] The control method provided in this embodiment displays a pop-up window prompting the user to turn off the modem when the electronic device disconnects from the satellite network. When the user's operation on the electronic device is determined to be turning off the modem, the electronic device controls the modem to be in a switched-off state. This reduces the power consumption of the modem when the electronic device is disconnected from the satellite network, thereby reducing the power consumption of the electronic device and allowing it to maintain a longer battery life. If the user is in an environment with no cellular network coverage or poor cellular network coverage and needs to wait for rescue, the longer battery life of the electronic device is beneficial for rescuing the user.

[0311] Optionally, between the first and second time points, the method also includes S904.

[0312] S904, at the fourth moment, the electronic device displays a second pop-up window. The second pop-up window includes a second control and a second prompt message, which indicates whether to enter power-saving mode.

[0313] For example, the second pop-up window could be Figure 4 The second pop-up window in the embodiment, for example Figure 5 The second pop-up window 501 is shown. The second control can be... Figure 4 The confirmation control included in the second pop-up window in the embodiment, for example Figure 5 The confirmation control 5011 is shown. The second prompt message is as follows: Figure 4 The second pop-up window in the embodiment includes a prompt message for entering the ultra-long standby mode, for example... Figure 5 The second pop-up window 501 in the embodiment contains the text "Enter ultra-long standby mode?".

[0314] The electronic device displays the first pop-up window in response to an operation on the second control.

[0315] For example, the second control can be Figure 4 The cancel control in the first pop-up window in the embodiment can be, for example, Figure 5 The cancel control 5022 in the embodiment. An operation on the second control is, for example, a click operation on the cancel control 5022.

[0316] In this way, by displaying a second pop-up window before the first pop-up window appears, the electronic device can be put into a state where the modem is on and the transceiver module associated with flight mode is off under the user's operation. This reduces the power consumption of the transceiver module associated with flight mode when the electronic device is searching for cellular networks, thus allowing the electronic device to maintain a longer battery life.

[0317] Optionally, the control method provided in this embodiment may further include S905-S908:

[0318] S905, at the fifth time, the electronic device receives an operation to activate satellite communication mode, and the electronic device connects to the satellite network. The fifth time is later than the third time.

[0319] For example, the operation of activating satellite communication mode can be found in [reference needed]. Figure 4 The operation of activating the satellite communication module shown in S400 of the embodiment will not be described again here.

[0320] S906, at the sixth time, the electronic device receives an operation to shut down the satellite communication mode, and the electronic device disconnects from the satellite network. The sixth time is later than the fifth time.

[0321] The specific implementation of S906 is similar to that of S901, and will not be described again in this embodiment.

[0322] S907, at the seventh moment, the electronic device displays the first pop-up window. The first pop-up window also includes a third control. The seventh moment is later than the sixth moment.

[0323] For example, the third control can be Figure 4 The cancel control in the first pop-up window in the embodiment can be, for example, Figure 5 Cancel control 5022 in the embodiment. The third control can also be... Figure 8 Cancel control 8012 in the embodiment.

[0324] S908, at the eighth moment, in response to an operation on the third control, the electronic device controls the modem to be turned on. The eighth moment is later than the seventh moment.

[0325] For example, an operation on a third control includes clicking the third control. If the third control is... Figure 4 The specific implementation principle and technical effect of the cancel control in the first pop-up window of the embodiment, which controls the modem to be in the on state by the electronic device, are as follows: Figure 4 The specific implementation principle and technical effect of S405 in the embodiment are similar, and will not be repeated here.

[0326] Optionally, after the eighth time point, the control method provided in this embodiment further includes: the modem searching for cellular networks according to a first periodic network search method. The network search interval of the first periodic network search method increases sequentially.

[0327] For example, the first periodic network search method could be Figure 4 The first periodic network search method in this embodiment. The specific implementation principle of the modem searching for cellular networks according to the first periodic network search method is as follows: Figure 4The specific implementation principle of S406 in the embodiment is similar and will not be repeated here. The network search interval of the first periodic network search method increases sequentially. By increasing the network search interval, the power consumption of the modem during network search can be reduced.

[0328] After the eighth moment, the control method provided in this embodiment also includes S909.

[0329] S909, at the ninth moment, the electronic device receives an operation to initiate a communication service, and the modem searches for the cellular network according to the second periodic network search method. The search interval of the second periodic network search method increases sequentially, and within the same period, the search interval of the second periodic network search method is smaller than the search interval of the first periodic network search method.

[0330] For example, the second periodic network search method could be Figure 4 The second periodic network search method in this embodiment. When an electronic device receives an operation to initiate a communication service, the modem searches for cellular networks according to the second periodic network search method. This helps the electronic device find a cellular network as quickly as possible, which can improve the user experience.

[0331] Optionally, in the first periodic network search method, when the search interval in the first periodic network search method reaches a first search interval threshold, the search interval in the first periodic network search method will no longer increase. In the second periodic network search method, when the search interval in the second periodic network search method reaches a second search interval threshold, the search interval in the second periodic network search method will no longer increase. The second search interval threshold is smaller than the first search interval threshold. This can reduce the probability of not being able to find a cellular network.

[0332] Optionally, before the modem searches for cellular networks according to the second periodic network search method, the control method provided in this embodiment further includes:

[0333] Electronic devices determine whether the modem's network search interval is greater than the network search interval threshold.

[0334] When the electronic device determines that the modem's network search interval is greater than the network search interval threshold, the modem searches for cellular networks according to the second periodic network search method.

[0335] For example, the search interval threshold can be Figure 4 The third search interval threshold in the embodiment.

[0336] This allows for a balance between timely cellular network searches and reduced network search power consumption.

[0337] Optionally, the control method provided in this embodiment further includes:

[0338] The electronic device determines whether its location is within a preset geofence. The preset geofence is an area without cellular network coverage or where cellular network access is unavailable. The specific implementation principle and technical effects of this step are... Figure 4 The specific implementation principle and technical effect of S407 in the embodiment are similar, and will not be repeated here.

[0339] When the electronic device determines that its location is within a preset geofence, the modem stops searching for cellular networks. The specific implementation principle of this step is... Figure 4 The specific implementation principle of S408 in the embodiment is similar and will not be repeated here. If the electronic device is within a preset geofence, the modem's network search is invalid, and the modem stops searching, which can reduce the power consumption of invalid network searches.

[0340] Optionally, in the third moment, in response to the operation on the first control, it also includes:

[0341] The electronic device controls at least one of the following: Wi-Fi, Bluetooth, NFC, or IR. For example, the electronic device controls all of these to be off. The specific implementation principle of this application embodiment is... Figure 4 The specific implementation principle of S404 in the embodiment is similar and will not be repeated here. Controlling at least one of the following—Wi-Fi, Bluetooth, NFC, or IR—of the electronic device can reduce power consumption and allow it to maintain a longer battery life.

[0342] Optionally, at the eighth moment, in response to the operation of the third control, the electronic device further includes: controlling the electronic device to turn off its Wi-Fi, Bluetooth, NFC, and IR. This reduces the power consumption of Wi-Fi, Bluetooth, NFC, and IR, thereby reducing the power consumption of the electronic device and allowing it to maintain a longer battery life.

[0343] Optionally, the electronic device displays a first pop-up window, including:

[0344] The electronic device determines whether the communication service before disconnecting from the satellite network was a satellite communication service. Satellite communication services include one or more of the following: satellite calls, sending and receiving satellite text messages, satellite video communication, and satellite voice communication.

[0345] If the electronic device determines that the communication service before it disconnected from the satellite network was a satellite communication service, the electronic device will display the first pop-up window.

[0346] For example, such as Figure 4 As shown in S401 of the illustrated embodiment, if the decision center receives a message indicating that the first fence has been triggered, it determines whether the previously received fence-triggered message was a message indicating that the second fence has been triggered. If so, the decision center reads the status flag of the satellite communication module. If the decision center reads a shutdown flag (or an enable flag), it determines that the communication service before the electronic device disconnects from the satellite network was a satellite communication service. Therefore, it can determine that the operation intent corresponding to the electronic device disconnecting from the satellite network is a power-saving intent. The electronic device can then display a first pop-up window to prompt the user to perform a power-saving operation, thereby improving the user experience.

[0347] Optionally, the electronic device displays a first pop-up window, including:

[0348] The electronic device determines whether the communication service before it disconnects from the satellite network is a satellite communication service.

[0349] If the electronic device determines that the communication service before it disconnected from the satellite network was not a satellite communication service, then it uses the most recently stored location information of the electronic device to determine whether the electronic device is in an area without cellular network coverage.

[0350] If the electronic device determines that it is in an area without cellular network coverage, it will display the first pop-up window.

[0351] For example, such as Figure 4 As shown in S401 of the illustrated embodiment, if the decision center receives a message indicating that the first fence has been triggered, it determines whether the previously received fence-triggered message is a message indicating that the second fence has been triggered. If not, the decision center can obtain the most recently stored location information of the electronic device to determine whether the area where the electronic device is located has no cellular network coverage. If it is determined that the area where the electronic device is located has no cellular network coverage, the decision center reads the status flag bit of the satellite communication module. If the decision center reads a closed flag (or disabled flag), the electronic device displays a first pop-up window to prompt the user to perform power-saving operations, improving the user experience.

[0352] The above embodiments of this application use signal transceiver modules associated with flight mode, including modem, wireless fidelity (Wi-Fi), Bluetooth (BT), near field communication (NFC), and infrared (IR), as examples to illustrate the control method of the embodiments of this application.

[0353] It is understood that the signal transceiver module associated with flight mode may include one or more of the following: modem, Wi-Fi, Bluetooth (BT), near-field communication (NFC), and infrared (IR). The module associated with flight mode can also be other configurable modules. These other configurable modules can be signal transceiver modules or processing modules. The control method proposed in this application is also applicable to scenarios where the signal transceiver module associated with flight mode includes one or more of the following: modem, Wi-Fi, BT, NFC, or IR. In scenarios where the signal transceiver module associated with flight mode includes one or more of the following: modem, Wi-Fi, BT, NFC, or IR, the specific implementation principle and technical effect of the control method provided in the embodiments of this application are similar to those in scenarios where the signal transceiver module associated with flight mode includes modem, Wi-Fi, BT, NFC, and IR. If other configurable modules are associated with flight mode, the control method provided in this application embodiment can also be used to control the opening and closing of other configurable modules. Its specific implementation principle and technical effects are similar to... Figure 4 The specific implementation principles and technical effects of controlling the opening and closing of Wi-Fi, BT, NFC, or IR in the embodiments are similar, and will not be repeated here.

[0354] The following diagrams, using user interface illustrations, illustrate scenarios of electronic devices connecting to and disconnecting from satellite networks.

[0355] 1. Scenarios where electronic devices access satellite networks or enable satellite communication mode ( Figures 9A-9G )

[0356] When the electronic device is powered on and / or unlocked, the electronic device can display... Figure 9A The interface shown. (As shown) Figure 9AThe interface shown may include a status bar, time "08:08", date "Thursday, December 3rd, the 19th day of the 10th month of the Gengzi year", icons for calendar application, cloud storage application, contacts application, settings application, video application, music application, satellite communication application (1001), theme application, phone application (1002), SMS application (1003), browser icon, and camera application icon.

[0357] exist Figure 9A On the interface, users can touch icon 1001, and the electronic device can display... Figure 9B The interface shown is for a satellite communication application. It should be understood that touch operations may include tapping or swiping.

[0358] like Figure 9B The interface shown may include a status bar, a return control, communication type prompts, an enable control 1004 indicating access to the satellite network, and information on supported card types.

[0359] The information displayed regarding supported card types can be used to inform users of the type of SIM card required for satellite communication or the operator to which the SIM card belongs. This reduces the probability of the inserted SIM card not supporting satellite communication, the probability of satellite connection failure due to the inserted SIM card not supporting satellite communication, and the probability of increased power consumption of electronic devices due to invalid satellite connections caused by the SIM card not supporting satellite communication. The supported card type information may include the text "Only supports China Telecom cards". The communication type information may include the text "Satellite communication connects heaven and earth, communication without boundaries". In some implementations, the communication type information may also be the text "Tiantong satellite communication connects heaven and earth, communication without boundaries". The enable control 1004 may contain the text "Enable" or "Enable Tiantong Satellite". In some implementations, the enable control 1004 may contain information about the enabled satellite type. The enabled satellite type information may include the text "Enable Tiantong Satellite".

Upon receiving a touch operation on the enable control 1004, the electronic device can search for satellites and display... Figure 9C The interface shown. (As shown) Figure 9CThe interface shown may include a return control and window 1005. Window 1005 may include a collapse control for closing window 1005, a close control 10051, a satellite search prompt, and an image indicating that satellite search is in progress. The satellite search prompt may include text such as "Please use this in an open area to avoid obstructing satellite signals." This prompt can guide the user's handheld electronic device posture or movements to quickly complete the satellite search, allowing the user to promptly use satellite communication functions.

[0361] In electronic device display Figure 9C In the interface shown, if the electronic device completes satellite acquisition, it can perform satellite alignment and display the results. Figure 9D The interface shown. (As shown) Figure 9D The interface shown includes window 1006. Window 1006 includes a collapse control for closing window 1006, a close control 10061, a satellite alignment prompt, and an image indicating that alignment is in progress. The satellite alignment prompt includes text such as "Turn your phone to the left to move the satellite to the fan-shaped area." This prompt guides the user's hand gestures or movements when holding the electronic device, enabling quick satellite alignment and allowing the user to promptly use satellite communication functions.

[0362] In electronic device display Figure 9D In the interface shown, if the electronic device is already aligned with the satellite, it can establish a communication connection with the satellite network and display [the information]. Figure 9E The interface shown. (As shown) Figure 9E The interface shown may include a return control and window 1007. Window 1007 includes a collapse control for closing window 1007, a close control 10071, a message indicating a communication connection is in progress, and an image indicating a connection to the satellite. The communication connection message may include text such as "Connecting (120 seconds) Aligned with satellite, please ensure there are no buildings or trees obstructing this direction." This communication connection message can be used to show the user the progress of accessing the satellite network, thus improving the user experience.

[0363] In electronic device display Figure 9E In the scenario shown, if the electronic device successfully connects to the satellite network, the electronic device can display... Figure 9F The interface shown. (As shown) Figure 9FThe interface shown may include a return control and a window 1008. Window 1008 includes a collapse control 10083 indicating that window 1008 is collapsed, a close control 10082, a message indicating that the satellite communication connection is successful, a signal indicator 10081 indicating the satellite signal strength, an image indicating the connection to the satellite, a phone application icon 1009, a text messaging application icon 1010, a location indicator, and location information.

[0364] Among them, the phone application icon 1009 and Figure 9A The difference between icon 1002 and icon 1009 in the interface shown is that icon 1009 includes a satellite icon, while icon 1002 does not. Icon 1009 includes a satellite icon, indicating that the user can make and receive calls via satellite network. The SMS app icon 1010 and... Figure 9A The difference between icon 1003 and icon 1010 for the SMS application in the interface shown is that icon 1010 includes a satellite icon, while icon 1003 does not. The presence of the satellite icon in icon 1010 indicates that the user can send and receive SMS messages via satellite network. The application associated with icon 1009 may be the same as or different from the application associated with icon 1002. Similarly, the application associated with icon 1010 may be the same as or different from the application associated with icon 1003.

[0365] The message indicating a successful satellite communication connection is displayed as text such as "Successfully connected to satellite. Current signal is good. Please maintain your handheld position." Location information is also displayed as text such as "40°10′41″N, 116°10′44″E, altitude 8848 meters." Location information may also include text such as "Refreshed: Just now." Both the successful satellite communication connection message and location information can be used to notify the user that their electronic device has connected to the satellite network, allowing the user to use satellite communication functions, thus improving the user experience. Using satellite communication functions includes making and receiving phone calls or sending and receiving text messages via the satellite network. Making and receiving phone calls via the satellite network can be understood as satellite calling, and sending and receiving text messages via the satellite network can be understood as sending and receiving satellite text messages.

[0366] In electronic device display Figure 9F In the interface shown, users can make and receive phone calls or send and receive text messages via satellite network.

[0367] exist Figure 9F On the interface shown, the user can touch the collapse control 10083, which represents the collapsed window 1008, and the electronic device can display... Figure 9G The interface shown. (As shown) Figure 9GThe interface shown includes a status bar, a collapsed window 1011 (window 1008), the text "Satellite communication connects heaven and earth, communication without boundaries," a phone application icon 1009, a text messaging application icon 1010, and a control 1012 indicating disconnection from the satellite network. Window 1011 may include a message indicating a successful satellite communication connection, location information, a signal indicator showing satellite signal strength, and an image showing the connection to the satellite.

[0368] In electronic device display Figure 9G In the interface shown, users can make and receive phone calls or send and receive text messages via satellite network.

[0369] It should be understood that electronic devices may display a message after a user finishes a call or text message exchange. Figure 9F The interface shown or Figure 9G The interface shown.

[0370] 2. Scenarios where electronic devices disconnect from satellite networks ( Figures 9G-9R )

[0371] On electronic devices Figure 9G On the interface shown, the user can perform touch operations on control 1012. Upon receiving a touch operation on control 1012, the electronic device can display... Figure 9H The interface shown. (As shown) Figure 9H The interface shown contains window 1015. Figure 9H Other content in the interface shown can be found in [link to relevant documentation]. Figure 9G The contents of the interface shown will not be described in detail here. Window 1015 includes the prompt "Are you sure you want to exit Tiantong satellite communication?", a control 10151 indicating exit, and a control 10152 indicating cancellation. This reduces the probability of users accidentally touching control 1012, causing the electronic device to lose its connection to the satellite network, thus improving the user experience.

[0372] exist Figure 9H On the interface shown, the user can touch control 10151 to turn off satellite communication mode. Upon receiving a touch operation on control 10151, the electronic device can disconnect from the satellite network, and the electronic device can display... Figure 9I The interface shown. Figure 9I The content of the interface shown can be found in [link / reference]. Figure 9BThe contents of the interface shown will not be repeated here. It should be understood that when the electronic device disconnects from the satellite network, the electronic device can control the modem, Wi-Fi, BT, NFC, and IR modules on the electronic device to return to their state before flight mode or remain on, so that the user can use the functions of the modem, Wi-Fi, BT, NFC, or IR modules in a timely manner.

[0373] In electronic device display Figure 9I In the interface shown, the electronic device can search for a network using either the second periodic network search method or the first periodic network search method. From the start of the network search by the modem until the first preset time is reached, if the network search fails, it indicates that there is no cellular network coverage or the cellular signal quality is poor in the area where the electronic device is located. The electronic device can then display... Figure 9J The interface shown. (As shown) Figure 9J The interface shown may include pop-up window 1016; other content within this interface can be found in [reference needed]. Figure 9I The content of the interface shown will not be described in detail here. Pop-up window 1016 includes an identifier for the System Manager service, the text "System Manager service just now," a prompt to enable Super Power Saving Mode, and a control 10161 indicating that Super Power Saving Mode is enabled. The prompt to enable Super Power Saving Mode includes text such as "Using Super Power Saving Mode can significantly save power. Satellite communication function detected." This prompts the user to enable Super Power Saving Mode to reduce the power consumption of electronic devices.

[0374] Optionally, on the electronic device display Figure 9I In the interface shown, the electronic device can perform a network search using the modem according to the second periodic network search method. If the electronic device fails to search for a network using the second periodic network search method, it indicates that the signal quality of the cellular network in the area where the electronic device is located is poor. The electronic device can then perform a network search using the first periodic network search method to further determine whether there is no cellular network coverage or poor cellular signal quality in the area where the electronic device is located. From the time the modem starts searching for a network until the first preset time is reached, if the network search fails, it indicates that there is no cellular network coverage or poor cellular signal quality in the area where the electronic device is located. The electronic device can then display... Figure 9J The interface shown.

[0375] Optionally, on the electronic device display Figure 9I In the case of the interface shown, the electronic device can execute step S407 to determine whether the electronic device is located in an area without cellular network coverage. If it is determined that the electronic device is located in an area without cellular network coverage, the electronic device can display... Figure 9J The interface shown prompts the user to enable the super power saving mode to reduce the power consumption of electronic devices.

[0376] Optionally, on the electronic device display Figure 9I In the interface shown, the electronic device can perform a network search using the first periodic network search method and the second periodic network search method. If the electronic device fails to search for a network, it indicates that there is no cellular network coverage or the cellular signal quality is poor in the area where the electronic device is located. The electronic device can then display... Figure 9J The interface shown. For details on the specific implementation principles and technical effects of the electronic device performing network searches according to the first and second periodic network search methods, please refer to [link to relevant documentation]. Figure 4 The specific implementation principle and technical effects of the electronic device in embodiment S406 performing network search according to the first periodic network search method and the second periodic network search method will not be described in detail here.

[0377] Optionally, after disconnecting from the satellite network, the electronic device displays... Figure 9J Before the interface shown, the electronic device can determine whether any of the received fence-triggered messages indicate that a second fence was triggered during the period when the electronic device maintained a connection with the satellite network. If so, it means that the user used satellite communication services through the electronic device during the period when the electronic device maintained a connection with the satellite network, which can further indicate that the user's area has no cellular network coverage or poor cellular signal quality. The electronic device can then display... Figure 9J The interface shown.

[0378] exist Figure 9J On the interface shown, the user can perform touch operations on control 10161 (which can be understood as a fourth control in some embodiments), and the electronic device can display... Figure 9K or Figure 9L The interface shown. (As shown) Figure 9K The interface shown may include pop-up window 1017; other content within this interface can be found in [reference needed]. Figure 9J The content of the interface shown will not be described in detail here. Pop-up window 1017 includes the text "Enable Super Power Saving Mode," a reminder to enable Super Power Saving Mode again, a control for selecting not to be reminded again, a control 10171 indicating that Super Power Saving Mode is enabled, and a control 10172 indicating that Super Power Saving Mode is disabled. The reminder to enable Super Power Saving Mode again may include the text "Dark mode will be enabled, disabling most power-consuming functions and applications and limiting phone performance. You can also add applications as needed. Do you want to enable Super Power Saving Mode?".

[0379] In some embodiments, Figure 9K On the interface shown, the user can touch control 10171, and the electronic device can then display... Figure 9LThe interface shown is as follows. Upon receiving a touch operation on control 10171, the electronic device can control applications such as the phone application corresponding to icon 1002, the SMS application corresponding to icon 1003, and the contacts application to be enabled, while controlling other applications on the electronic device to be disabled. It can also control the display refresh rate to a preset refresh rate value and / or adjust the display brightness to a preset brightness. Furthermore, it can control modules such as Wi-Fi, BT, NFC, and IR on the electronic device to be disabled, and control the modem to be in a low-power state, thus putting the electronic device into a super power-saving mode to reduce power consumption. The electronic device can display... Figure 9L The interface shown. (As shown) Figure 9L The interface shown includes a status bar, an icon 1018 indicating Super Power Saving Mode, a control 1019 indicating exiting Super Power Saving Mode, time, date, battery life information, icons for the phone app 1002, the SMS app 1003, the contacts app, and an icon 1020 for adding an app. The battery life information includes text such as "Battery 100%, estimated usage 124 hours 25 minutes."

[0380] In this context, a low-power modem indicates that the modem is not powered off but cannot search for networks. Controlling the modem to a low-power state reduces power consumption and allows it to quickly return to power or operational status and begin network searching when an electronic device instructs it to do so, thus improving user experience. For example, when an electronic device receives a command to turn on the modem, it can control the modem to return to power or operational status.

[0381] Understandably, when an electronic device is in ultra-low power mode, it has disconnected from both the satellite network and the cellular network. Figure 9L On the interface shown, users can perform touch operations on the phone or SMS applications. If a touch operation is received on the phone or SMS application, it indicates that the user intends to make a call or send a text message. The electronic device's display screen can then show a window prompting the user to enable satellite communication mode or turn on the modem.

[0382] Optionally, in Figure 9L On the interface shown, users can touch icon 1020 to add a target application. The target application can be any of the other applications currently closed on the electronic device. After adding the target application, its icon will appear. Figure 9L The interface shown is displayed.

[0383] In some embodiments of this application, when the electronic device is disconnected from the satellite network (in which case the satellite modem may be in a turned-off state), the modem of the electronic device is in an on or working state, and the power consumption of the modem in the on or working state is relatively high. Therefore, in order to reduce the power consumption of the electronic device, when the electronic device receives a signal from the satellite network, the modem is in an on or working state. Figure 9K When the control 10171 (which can be understood as a fourth control in some embodiments) in the pop-up window 1017 is touched, the electronic device can display... Figure 9M The interface shown (where) Figure 9M The pop-up window 1016 in the middle can be displayed or not, or it can be displayed. Figure 9N The interface shown. (As shown) Figure 9M The interface shown may include a first pop-up window 502 for reducing the power consumption of the modem (in this case, a cellular modem). Other content within this interface can be found in [reference needed]. Figure 9K The content of the interface shown will not be repeated here. Thus, the first pop-up window 502 (which in some embodiments can be understood as the eighth control) can prompt the user to turn off the modem (or prompt the user to control the modem to enter a low-power state or a turned-off state), thereby stopping or reducing the search for cellular networks and thus reducing the power consumption of the electronic device. It should be noted that... Figure 9M or Figure 9N The example shown uses the Super Power Saving Mode without reducing Modem power consumption. In other embodiments, the Super Power Saving Mode may include reducing Modem power consumption. Thus, the first pop-up window 502 no longer needs to be displayed as a separate window; for example, it can be displayed in pop-up window 1016 as an option within the Super Power Saving Mode.

[0384] exist Figure 9M On the interface shown, the user can touch the confirmation control 5021 in the first pop-up window 502. Upon receiving a touch operation on the confirmation control 5021, the electronic device can enable applications such as the phone application (icon 1002), the SMS application (icon 1003), and the contacts application (icon 1003) (enabled applications are displayed on the interface), and disable other applications on the electronic device (disabled applications are not displayed on the interface). It can also control the screen refresh rate to a preset value and / or adjust the screen brightness to a preset value. Furthermore, it can disable modules such as Wi-Fi, BT, NFC, and / or IR, and control the modem to be in a low-power state or off, thus putting the electronic device into a super power-saving mode. The electronic device can display... Figure 9L The interface shown.

[0385] In some embodiments of this application, when the electronic device receives an instruction such as Figure 9K When the control 10171 is touched, if the electronic device determines that the user is moving, it can control applications such as the phone application (corresponding to icon 1002), the SMS application (corresponding to icon 1003), and the contacts application to be open, and control other applications on the electronic device to be closed. It can also control the screen refresh rate to a preset refresh rate value and / or adjust the screen brightness to a preset brightness. Furthermore, it can control modules such as Wi-Fi, BT, NFC, and IR on the electronic device to be closed or in a low-power state, and control the modem to remain open or in operation. The electronic device can display... Figure 9L The interface shown.

[0386] If the electronic device is disconnected from the satellite network, and the network search fails within the second preset time interval from the start of the modem's search, it indicates that the user has not moved to an area with cellular network coverage or a strong cellular network signal. The electronic device may display... Figure 9N The interface shown. (As shown) Figure 9N The interface shown may include a first pop-up window 502; other content in this interface can be found in [reference needed]. Figure 9L The content of the interface shown will not be repeated here. The second preset duration can be longer than the first preset duration. In this way, if the electronic device disconnects from the satellite network and the user has not moved to an area with cellular network coverage or a good cellular network signal, the user can be prompted to turn off the modem to reduce the power consumption of the modem when searching for a network.

[0387] In some embodiments of this application, the electronic device is powered on and / or unlocked, and displays... Figure 9A In the case of the interface shown, Figure 9A On the interface shown, users can touch the icons of the settings application, and the electronic device can display... Figure 9O The settings application interface is shown below. Figure 9O The interface shown includes option 1013 for satellite communication.

[0388] exist Figure 9O On the interface shown, the user can touch option 1013. Upon receiving a touch operation on option 1013, the electronic device can search for satellites and display the result. Figure 9C The interface shown allows for the implementation of... Figures 9C-9G This allows for the establishment of satellite communication services. In this way, users can reduce their reliance on services such as... Figure 9B The touch operation of the enabled control 1004 allows electronic devices to connect to the satellite network as quickly as possible, improving the user experience.

[0389] Understandably, if the electronic device is receiving a message from... Figure 9O If the user accesses the satellite network via touch operation of option 1013 in the interface shown, then upon receiving a request... Figure 9H When the control 10151 in the interface shown is touched, the electronic device can display... Figure 9P The interface shown. Figure 9P The content of the interface shown can be found in [link / reference]. Figure 9O The contents of the interface shown will not be described again here.

[0390] In electronic device display Figure 9P In the interface shown, the electronic device can search for a network using either the second periodic network search method or the first periodic network search method. From the start of the network search by the modem until the first preset time is reached, if the network search fails, it indicates that there is no cellular network coverage or the cellular signal quality is poor in the area where the electronic device is located. The electronic device can then display... Figure 9Q The interface shown. (As shown) Figure 9Q The interface shown may include pop-up window 1016; other content within this interface can be found in [reference needed]. Figure 9P The content of the interface shown will not be described again here. This allows the user to be prompted to activate the super power-saving mode when there is no cellular network coverage or poor cellular signal quality in the area where the electronic device is located, in order to reduce the power consumption of the electronic device.

[0391] In some embodiments of this application, when the electronic device is unlocked (e.g., display...), Figure 9A In the case of the interface shown, the user can perform a pull-down operation from the top of the electronic device or a pull-up operation from the bottom of the electronic device, and the electronic device can display... Figure 9R The control center interface is shown below. Figure 9R The interface shown may include satellite communication controls 1014.

[0392] exist Figure 9R On the interface shown, the user can perform touch operations on control 1014, and the electronic device can display... Figure 9B The interface shown. In Figure 9B On the interface shown, users can touch control 1004, and the electronic device can search for and display satellite signals. Figure 9C The interface shown allows for the implementation of... Figures 9C-9G This allows for the establishment of satellite communication services. This enables users to access satellite communication modes through multiple different entry points, enhancing the user experience.

[0393] In some embodiments of this application, when the electronic device is unlocked, the user can perform a pull-down operation from the top of the electronic device or a pull-up operation from the bottom of the electronic device, and the electronic device can display... Figure 9R The control center interface is shown below. Figure 9R The interface shown may include satellite communication controls 1014.

[0394] exist Figure 9R On the interface shown, users can touch control 1014, and the electronic device can search for and display satellite signals. Figure 9C The interface shown allows for the implementation of... Figures 9C-9G This allows for the establishment of satellite communication services. In this way, users can reduce their reliance on services such as... Figure 9B The touch operation of the enable control 1004 allows electronic devices to quickly access the satellite network or establish a communication connection with the satellite, thus improving the user experience.

[0395] In some embodiments of this application, during the process of establishing a connection between the electronic device and the satellite network, or while the electronic device maintains a connection with the satellite network, the electronic device may display a sixth pop-up window. The sixth pop-up window may include information prompting the user whether to enable screen power saving mode and a control indicating whether screen power saving mode is enabled. Upon receiving a touch operation on the control indicating that screen power saving mode is enabled, the electronic device may control the display refresh rate to a preset refresh rate and / or adjust the display brightness to a preset brightness to reduce the power consumption of the electronic device.

[0396] In some embodiments of this application, if the electronic device recognizes that the satellite communication service it is conducting has ended before disconnecting from the satellite network, it may indicate that there is no cellular network coverage or the cellular signal quality is poor in the user's area, and the user's communication service through the satellite network has ended (e.g., the satellite phone has been hung up or the satellite SMS has been sent). The user may wait for rescue while the electronic device remains connected to the satellite network. In this case, the display screen of the electronic device may display a sixth pop-up window to prompt the user to turn on the screen power saving mode, thereby reducing the power consumption of the electronic device in satellite communication mode while waiting for rescue.

[0397] Understandably, if Figures 9C-9F As shown, in Figures 9C-9F Every interface in the system contains a close control. For example, the close control... Figure 9C The close control 10051 in Figure 9D The close control 10061 in Figure 9E The close control 10071 or Figure 9F The close control 10082 is displayed on the electronic device. Figures 9C-9FIn any interface of the electronic device, the user can touch the close control on the screen displayed on the electronic device. Upon receiving a touch operation on the close control, the screen displayed on the electronic device may also include, for example: Figure 9H The window 1015 shown in the image. This reduces the probability of users accidentally touching the close control, causing the electronic device to lose its communication connection with the satellite network, thus improving the user experience.

[0398] In the embodiments of this application, such as Figure 9A -Figure G, Figure 9O and Figure 9R As shown, during the process of an electronic device connecting to a satellite network, the device can display different windows to guide the user's hand gestures or movements, facilitating a faster connection and enabling the user to quickly utilize satellite communication functions, thus improving the user experience. Once connected to the satellite network, the user can use satellite communication functions, such as making and receiving calls or sending and receiving text messages, enabling communication with the outside world via satellite when cellular networks are unavailable. Figure 9G-Figure 9Q As shown, upon receiving an operation indicating that satellite communication mode should be turned off, the electronic device can disconnect from the satellite network. If the electronic device determines that the user used satellite communication services during the period when the device was connected to the satellite network, and / or if the device failed to find a network, the electronic device can prompt the user to enable ultra-low power mode. Upon receiving an operation indicating that the user should enable ultra-low power mode, the electronic device can keep the phone, SMS, and contacts applications running and keep other applications off. It can also control the screen refresh rate to a preset value and / or adjust the screen brightness to a preset value. Furthermore, it can keep modules such as the modem, Wi-Fi, BT, NFC, and IR off or in a low-power state, thus enabling the electronic device to operate in ultra-low power mode and reduce power consumption. While in ultra-low power mode, if the electronic device receives a touch operation on the phone or SMS application, indicating the user's intention to make a call or send a text message, the screen can display a window prompting the user to enable satellite communication mode or turn on the modem.

[0399] This application also provides a control method, which may include:

[0400] At the tenth moment, the electronic device received an operation to turn off the satellite communication mode, and the electronic device disconnected from the satellite network.

[0401] At the eleventh moment, the electronic device displays a fourth pop-up window. This fourth pop-up window includes a fourth control and a third prompt message, which asks whether to enable the ultra-low power mode. The eleventh moment is later than the tenth moment.

[0402] At the twelfth moment, in response to the operation on the fourth control, the super power saving mode is activated. The twelfth moment is later than the eleventh moment.

[0403] For example, receiving an operation to turn off satellite communication function (also known as turning off satellite communication mode) from an electronic device can be an operation performed by a user on the electronic device's interface to exit the satellite communication function. This operation may include a user tap (or touch). Figure 9G The operation of the "Disconnect" control 1012 in the middle, and may further include user actions. Figure 9H The tenth moment can be the moment when the electronic device disconnects from the satellite network upon receiving a touch operation on the control 10151.

[0404] The fourth pop-up window can be Figure 9J Pop-up window 1016 in the middle. The eleventh moment can be displayed on electronic devices. Figure 9J The time shown on the interface can also be displayed on an electronic device. Figure 9Q The moment the interface is shown. The fourth control can be control 10161 in pop-up window 1016. The third prompt message can be a prompt message in pop-up window 1016 to enable super power saving mode, such as "Using super power saving mode can significantly save power. Satellite communication function has been detected." Operation on the fourth control can be a touch operation on control 10161. In response to a touch operation on control 10161, the electronic device can enable super power saving mode. For example, in response to a touch operation on control 10161, the electronic device can control the phone application corresponding to icon 1002, the SMS application corresponding to icon 1003, and the contacts application to be turned on, and control the other applications on the electronic device to be turned off. It can also control the refresh rate of the display screen to a preset refresh rate value and / or adjust the brightness of the display screen to a preset brightness. It can also control one or more of the modules such as Wi-Fi, BT, NFC, or IR on the electronic device to be turned off, and control the modem to be in a low power state, so that the electronic device is in super power saving mode to reduce the power consumption of the electronic device. The twelfth moment can be the moment when the electronic device starts to enable super power saving mode. The twelfth moment can also be the moment when the electronic device displays Figure 9L The interface shown is for a specific time. It is understandable that modules such as Wi-Fi, BT, NFC, and IR on electronic devices can be selectively configured.

[0405] In this way, when the electronic device is disconnected from the satellite network, a fourth pop-up window will appear, prompting the user whether to enable the super power saving mode. Upon receiving the enable command, the user can enable the super power saving mode to reduce the power consumption of the electronic device.

[0406] Optionally, enable the Ultra Power Saving Mode, including:

[0407] The modem controlling the electronic device is in a low-power state, and the device's Wi-Fi, Bluetooth, NFC, and IR are all turned off. The screen brightness is also set to a preset level. A low-power modem indicates that it is not searching for cellular networks.

[0408] In this way, by shutting down multiple modules and reducing screen brightness, the electronic device is put into a super power-saving mode to reduce power consumption. The modem being in a low-power state indicates that it is not powered off, and it can be quickly restored to working status when the user needs to.

[0409] Optionally, in response to an operation on the fourth control, the method further includes:

[0410] The electronic device displays a fifth pop-up window. This fifth pop-up window includes a fifth control and a fourth prompt message. The fourth prompt message again asks whether to enable the Super Power Saving Mode, and explains the limitations on the electronic device's functions and applications after enabling Super Power Saving Mode.

[0411] Enabling Super Power Saving Mode can include: starting Super Power Saving Mode upon receiving an operation on the fifth control.

[0412] For example, the fifth pop-up window could be Figure 9K Pop-up window 1017. The fifth control can be control 10171 in pop-up window 1017. The fourth prompt message can include the message in pop-up window 1017 reminding users to turn on the super power saving mode again. The fourth prompt message can also include the text "Turn on super power saving mode" in pop-up window 1017. The specific implementation principle of starting super power saving mode when receiving an operation on the fifth control is similar to the specific implementation principle of the electronic device turning on super power saving mode in response to a touch operation on control 10161, and will not be described in detail here.

[0413] This allows a fifth pop-up window to appear before the fourth one, prompting the user again whether to enable the Super Power Saving Mode and indicating the limitations on the electronic device's functions and applications after enabling Super Power Saving Mode. Users can then decide whether to enable Super Power Saving Mode based on the prompts, thus improving the user experience.

[0414] Optionally, before the electronic device displays the fourth pop-up window, the method further includes: the modem of the electronic device searching for cellular networks, and determining whether the modem has successfully searched for networks from the moment it begins searching for cellular networks until a first preset time period is reached. For its specific implementation principle and technical effects, please refer to the electronic device display... Figure 9I The interface shown will then be displayed. Figure 9J The specific implementation principles and technical effects of the interface shown will not be elaborated here.

[0415] The electronic device displays a fourth pop-up window, including when the modem fails to search for a network.

[0416] This allows the system to prompt the user to activate Ultra Power Saving Mode when a network search fails. An unsuccessful network search indicates a lack of cellular network coverage or poor cellular signal quality in the user's area; activating Ultra Power Saving Mode reduces the power consumption of electronic devices.

[0417] Optionally, the method further includes:

[0418] At the thirteenth moment, the communication connection between the electronic device and the satellite network was established. The electronic device displayed a sixth pop-up window, which included a sixth control and a fifth prompt message. The fifth prompt message prompted whether to enable screen power saving mode. Screen power saving mode sets the refresh rate of the electronic device's display to a preset refresh rate and / or the brightness of the electronic device's display to a preset brightness. The thirteenth moment is earlier than the tenth moment.

[0419] At the fourteenth moment, in response to the operation on the sixth control, the screen power saving mode is activated. The fourteenth moment is later than the thirteenth moment.

[0420] For example, the thirteenth moment could be an electronic device display. Figure 9F The time shown on the interface can also be displayed on an electronic device. Figure 9G The moment shown on the interface. The sixth control can be the control in the sixth pop-up window that indicates the screen power saving mode is enabled. Operation on the sixth control can be a touch operation on the sixth control. The fourteenth moment can be the moment when the electronic device receives a touch operation on the sixth control.

[0421] This allows the user to be prompted to turn on screen power saving mode once the communication connection with the satellite network is established, thereby reducing the power consumption of electronic devices.

[0422] Optionally, before the tenth moment, the method further includes: enabling satellite communication services on electronic devices. Satellite communication services include one or more of the following: satellite calling, sending and receiving satellite text messages, satellite video communication, and satellite voice communication.

[0423] This allows the device to disconnect from the satellite network and prompt the user to activate a super power-saving mode when the electronic device has started satellite communication services and received an instruction to turn off satellite communication mode, thereby reducing the power consumption of the electronic device. The fact that a user has used satellite communication services could indicate that the user's area lacks cellular network coverage or has poor cellular signal quality, or it could mean that the user is waiting for rescue. Therefore, prompting the user to activate the super power-saving mode can reduce the power consumption of the electronic device while waiting for rescue.

[0424] Optionally, the method further includes:

[0425] At the fifteenth moment, an operation to terminate satellite communication services is received. The electronic device displays a sixth pop-up window, which includes a sixth control and a fifth prompt message. The fifth prompt message asks whether to enable screen power saving mode. Screen power saving mode sets the electronic device's screen refresh rate to a preset refresh rate and / or the screen brightness to a preset brightness. Satellite communication services include one or more of the following: satellite calls, sending and receiving satellite SMS messages, satellite video communication, and satellite voice communication. The fifteenth moment is earlier than the tenth moment.

[0426] At the sixteenth moment, in response to the operation on the sixth control, the screen power saving mode is activated. The sixteenth moment is later than the fifteenth moment.

[0427] For example, operations to terminate satellite communication services include hanging up a satellite call, exiting the application corresponding to icon 1009, or exiting the application corresponding to icon 1010. The fifteenth moment can be the moment when the operation to terminate satellite communication services is received. The fifteenth moment can also be the moment when screen power-saving mode is activated.

[0428] In this way, when satellite communication services are terminated, users are prompted to turn on screen power saving mode to reduce the power consumption of electronic devices.

[0429] Optionally, before the tenth time, the method further includes: the electronic device searching for satellites. If the electronic device finds a satellite, it performs satellite pairing. If the electronic device completes satellite pairing, it establishes a communication connection with the found satellite.

[0430] Thus, before connecting to the satellite network, the electronic equipment performs satellite search, satellite alignment, and communication connection establishment to achieve this connection. For details on the specific implementation principles of satellite search, satellite alignment, and communication connection, please refer to [link to relevant documentation]. Figures 9C-9E The specific implementation principle shown will not be elaborated here.

[0431] It is understood that the first moment, the second moment, the third moment, ... in the embodiments of this application are used to indicate the sequential order of the steps performed by the electronic device, rather than a limitation on specific moments.

[0432] This application also provides a control method, which may include:

[0433] The electronic device received an operation to disable satellite communication.

[0434] In response to receiving an operation to disable satellite communication, the electronic device disconnects from the satellite network.

[0435] After the electronic device disconnects from the satellite network, a fourth pop-up window appears. This fourth pop-up window includes a fourth control for enabling the first power-saving mode.

[0436] In response to receiving an operation on the fourth control, the first power-saving mode is activated.

[0437] For example, the first power-saving mode may reduce the power consumption of an electronic device by controlling some components of the electronic device, thereby achieving power saving. Some components of the electronic device may include one or more of a cellular modem, Wi-Fi, BitTorrent, NFC, or Infrared Radiator (IR). The first power-saving mode may be an ultra-power-saving mode. For example, the electronic device controls one or more of a cellular modem, Wi-Fi, BitTorrent, NFC, or IR to be in a switched-off or low-power state to reduce the power consumption of the components in the switched-off or low-power state, thereby achieving power saving.

[0438] For example, the first power-saving mode can also be achieved by controlling some components to save power in cellular communication mode. For instance, the electronic device can control one or more of Wi-Fi, BT, NFC, or IR to be in a turned-off or low-power state, and can control the cellular modem to be in an active state, so as to reduce the power consumption of the electronic device when the cellular modem successfully searches for a network and the electronic device is connected to the cellular network, thereby achieving the purpose of saving power in cellular communication mode.

[0439] When the first power-saving mode is the ultra power-saving mode, the fourth control, for example... Figure 9J Control 10161 in the middle.

[0440] In this way, when the electronic device is disconnected from the satellite network, a fourth pop-up window will appear, prompting the user whether to enable the first power-saving mode. Upon receiving the instruction to enable the first power-saving mode, the user can enable the first power-saving mode to reduce the power consumption of the electronic device.

[0441] Optionally, the fourth pop-up window also includes a third prompt message, which is used to indicate that satellite communication function has been detected.

[0442] It is understood that "having enabled satellite communication functionality" can be interpreted as having activated satellite communication functionality and / or having used satellite communication services. Activating satellite communication functionality can include one or more of the following: electronic device searching for satellites, electronic device aligning with satellites, or electronic device establishing a communication connection with a satellite.

[0443] Satellite communication function was detected to have been enabled. For example, satellite communication function was detected to have been disabled.

[0444] In this way, detecting that satellite communication has been enabled can indicate that there is no cellular network coverage or poor cellular signal quality in the area where the electronic device is located, thus prompting the user to turn on the first power-saving mode, which can improve the user experience.

[0445] Optionally, before the electronic device displays the fourth pop-up, the method also includes: the electronic device's cellular modem searching for cellular networks.

[0446] The electronic device displays a fourth pop-up window, which occurs when the cellular modem fails to search for a cellular network within a first preset time period. The start time of the first preset time period can have several possible scenarios, as follows:

[0447] For example, from the moment the electronic device turns off its satellite communication function until the first preset time period is reached, if the cellular modem fails to search for a cellular network, the electronic device displays a fourth pop-up window.

[0448] For example, if the cellular modem fails to search for a cellular network after a first preset time period has elapsed since the start of the cellular modem's search for the cellular network, the electronic device displays a fourth pop-up window.

[0449] For example, from the moment the cellular modem begins to operate until the first preset time period is reached, if the cellular modem fails to search for a cellular network, the electronic device displays a fourth pop-up window.

[0450] For example, the first preset duration can be 30 seconds, or it can be other values.

[0451] If the search for a cellular network fails within the first preset time period, it indicates that the electronic device is located in an area with no cellular network coverage or poor cellular signal quality. In this case, the electronic device displays a fourth pop-up window, prompting the user to activate the first power-saving mode to reduce the power consumption of the electronic device.

[0452] Optionally, a first power-saving mode is activated, including at least one of the following: The cellular modem of the electronic device is controlled to be in a powered-off or low-power state; or, the Wi-Fi communication module of the electronic device is controlled to be in a powered-off or low-power state; or, the Bluetooth BT communication module of the electronic device is controlled to be in a powered-off or low-power state; or, the NFC module of the electronic device is controlled to be in a powered-off or low-power state; or, the display of the electronic device adjusts the display mode of the interface to reduce the power consumption of the electronic device.

[0453] It is understandable that a component being in a "shutdown" state can mean that the component is powered off. A component being in a "low-power" state can mean that the component is not powered off but cannot function properly. The power consumption of a component in a shutdown or low-power state is less than the power consumption of a component in an operating state. A component being in an operating state indicates that the component is functioning normally.

[0454] Controlling the display screen of an electronic device to adjust the display mode of the interface in order to reduce the power consumption of the electronic device, for example: the electronic device adjusts the brightness of the display screen to a first brightness threshold, and / or adjusts the refresh rate of the display screen to a first refresh rate threshold.

[0455] This reduces the power consumption of electronic devices.

[0456] Optionally, before the electronic device receives an operation to disable satellite communication, the method further includes: establishing a communication connection between the electronic device and the satellite network. After the electronic device establishes a communication connection with the satellite network, the electronic device displays a sixth pop-up window, which includes a sixth control for enabling a second power-saving mode. In response to receiving an operation on the sixth control, the second power-saving mode is enabled.

[0457] The second power-saving mode can achieve power saving in satellite communication mode by controlling some components.

[0458] For example, enabling the second power-saving mode may include controlling the display screen of an electronic device to adjust the way the interface is displayed in order to reduce the power consumption of the electronic device.

[0459] For example, in response to receiving an operation on the sixth control, the electronic device may perform one or more of the following: adjust the display brightness to a second brightness threshold; or adjust the display refresh rate to a second refresh rate threshold; or control other components to be in a powered-off or low-power state. These other components may be components on the electronic device unrelated to satellite communication functionality.

[0460] This reduces the power consumption of electronic devices. The second brightness threshold can be the same as or different from the first brightness threshold. For example, the second brightness threshold may be higher than the first brightness threshold. Similarly, the second refresh rate threshold can be the same as or different from the first refresh rate threshold. For example, the second refresh rate threshold may be higher than the first refresh rate threshold. Establishing a communication connection between the electronic device and a satellite network can also be referred to as establishing a communication connection between the electronic device and a satellite. Optionally, the second power-saving mode can be a screen power-saving mode.

[0461] Optionally, before the electronic device receives an operation to disable satellite communication, the method further includes: enabling satellite communication services on the electronic device. Satellite communication services include one or more of the following: satellite calling, sending and receiving satellite text messages, satellite video communication, and satellite voice communication.

[0462] Enabling satellite communication on an electronic device indicates that there is no cellular network or the cellular signal quality is poor in the area where the device is located. Therefore, upon receiving an instruction to disable satellite communication, the electronic device can prompt the user to activate its first power-saving mode to reduce power consumption and extend battery life.

[0463] Satellite calling can refer to calls made using a mobile phone's telephone application via a satellite network.

[0464] Satellite video communication includes, for example, video calls via satellite networks using applications such as WeChat or QQ. Satellite voice communication includes, for example, voice calls via satellite networks using applications such as WeChat or QQ.

[0465] Optionally, the method further includes: after the satellite communication service ends (e.g., after receiving an operation to end the satellite communication service), the electronic device displays a seventh pop-up window, which includes a seventh control for enabling a third power-saving mode. In response to receiving an operation on the seventh control, the third power-saving mode is enabled.

[0466] For example, after the satellite communication service ends, but the satellite communication function is not turned off, the electronic device may display a seventh pop-up window. The satellite communication function not being turned off can be understood as still being in satellite communication mode, or as still maintaining a communication connection with the satellite.

[0467] For example, upon receiving an operation to terminate satellite communication services, the electronic device may display a seventh pop-up window.

[0468] For example, in response to receiving an operation on the seventh control, the electronic device performs one or more of the following to enable the third power-saving mode: The electronic device adjusts the display brightness to a third brightness threshold; or, adjusts the display refresh rate to a third refresh rate threshold; or, controls other components to be in a powered-off or low-power state.

[0469] This reduces the power consumption of electronic devices.

[0470] The third power-saving mode can achieve power saving in satellite communication mode by controlling some components.

[0471] Among the three power-saving modes—the first, second, and third—the power-saving modes can be completely different from each other, or two of the three power-saving modes can be the same, for example, the second and third power-saving modes can be identical. The three power-saving modes can perform different degrees of power reduction operations on the electronic device in different scenarios, can reduce power consumption for different numbers of devices, or can use different parameter values ​​to reduce power consumption for the same device. For example, the electronic device adjusts the display brightness to a first brightness threshold to achieve power reduction in the first power-saving mode. The electronic device adjusts the display brightness to a second brightness threshold to achieve power reduction in the second power-saving mode.

[0472] The third brightness threshold can be the same as or different from the second brightness threshold. The third refresh rate threshold can also be the same as or different from the second refresh rate threshold.

[0473] Optionally, after receiving an operation on the fourth control, the method further includes: the electronic device displaying an eighth pop-up window, which includes an eighth control for reducing the power consumption of the cellular modem. In response to receiving an operation on the eighth control, the electronic device's cellular modem is controlled to be in a powered-off state or a low-power state.

[0474] For example, the eighth pop-up window can be the first pop-up window 502. The eighth control can be the confirmation control 5021 in the first pop-up window 502. Upon receiving an operation on the fourth control, the electronic device controls the cellular modem to be in an active state, and the electronic device can perform one or more of the following: control the electronic device's Wi-Fi communication module to be in a powered-off or low-power state; or control the electronic device's Bluetooth BT communication module to be in a powered-off or low-power state; or control the electronic device's NFC module to be in a powered-off or low-power state; or control the electronic device's infrared IR module to be in a powered-off or low-power state; or control the electronic device's display screen to adjust the display mode of the interface to reduce the power consumption of the electronic device.

[0475] If the cellular modem fails to find a network, the electronic device may display an eighth pop-up window. In response to receiving an operation on the eighth control, the cellular modem of the electronic device is switched off or into a low-power state.

[0476] This reduces the power consumption of electronic devices.
