[0022] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] In this article, the character " / " generally indicates that the objects before and after it are in an "or" relationship. For example, A / B can be understood as A or B.

[0024] The terms “first” and “second” in the specification and claims of this disclosure are used to distinguish different objects, rather than to describe a particular order of objects.

[0025] Furthermore, the terms “comprising” and “having”, and any variations thereof, used in the description of this disclosure are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or modules is not limited to the steps or modules listed, but may optionally include other steps or modules not listed, or may optionally include other steps or modules inherent to such process, method, product, or apparatus.

[0026] Furthermore, in this disclosure, the terms "exemplary" or "for example" are used to describe examples, illustrations, or descriptions. Any embodiment or design described in this disclosure using the terms "exemplary" or "for example" should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present concepts in a concrete manner.

[0027] With the maturity and widespread adoption of cloud computing technology, cloud-based terminals (such as cloud phones and cloud computers) have emerged and begun to gain popularity. Cloud computers centralize hardware resources such as computing power, memory, storage, and network resources in the cloud for management. Users only need a basic cloud computer and an internet connection to enjoy the high-performance experience of cloud computing. In other words, all application service data on a cloud computer is processed in the cloud, and the results are displayed as video on the cloud computer. Therefore, cloud terminals require a low-latency network to achieve the same user experience as local terminals.

[0028] However, due to the limited size of cloud terminal devices, the capacity of the batteries installed inside them is relatively low. When users take cloud terminal devices out and about, relying solely on the internal battery for power without an external power source, it is difficult for the devices to maintain a long battery life. Therefore, improving the battery life of cloud terminal devices has become an urgent technical problem to be solved.

[0029] For example, 5G (5th Generation Mobile Communication Technology) features low latency, allowing cloud terminals to interact with the cloud via 5G networks, thus improving user experience. However, 5G consumes relatively high power, which affects the battery life of cloud terminals.

[0030] To address the aforementioned problems, this disclosure provides a power consumption control method applied to a cloud terminal. The cloud terminal includes a cellular communication module, which enables the cloud terminal to establish a communication connection with a cellular network. In this power consumption control method, usage information of the cloud terminal can be sent to a server, representing the usage status of the cloud terminal. Subsequently, power-saving control commands sent by the server can be received, and the cellular communication module can be controlled to perform power-saving operations. In this way, by controlling the cellular communication module to perform power-saving operations, the power consumption of the cellular communication module is reduced, thereby reducing the power consumption of the cloud terminal.

[0031] To facilitate understanding of the embodiments of this disclosure, the communication system applicable to the embodiments of this disclosure will be described in detail first using the communication system shown in FIG1 as an example. Exemplarily, FIG1 is a schematic diagram of the architecture of a communication system to which the power consumption control method according to the embodiments of this disclosure applies. As shown in FIG1, the communication system includes a cloud terminal and a server.

[0032] A cloud terminal can be a device with transceiver capabilities. Cloud terminals can be deployed on land (including indoors or outdoors, handheld or vehicle-mounted); on water (e.g., on ships); and in the air (e.g., on airplanes, balloons, and satellites). Cloud terminals include handheld devices, vehicle-mounted devices, wearable devices, or computing devices with wireless communication capabilities. For example, a cloud terminal can be a mobile phone, tablet computer, or computer with wireless transceiver capabilities. Cloud terminal devices can also be virtual reality (VR) cloud terminal devices, augmented reality (AR) cloud terminal devices, wireless cloud terminals in industrial control, wireless cloud terminals in autonomous driving, wireless cloud terminals in telemedicine, wireless cloud terminals in smart grids, wireless cloud terminals in smart cities, wireless cloud terminals in smart homes, etc.

[0033] In this embodiment, the cloud terminal may include a function control module, a cellular communication module, and a battery. The function control module controls the hardware functions of the cloud terminal (e.g., user interface (UI) display, audio, WiFi (Wireless Fidelity), Ethernet port, keyboard and mouse, Bluetooth, etc.), but it does not have the ability to interact with the air interface network. The cellular communication module enables the cloud terminal to establish a communication connection with the cellular network. For example, the cellular communication module can process information between the cloud terminal and the air interface 4G / 5G network.

[0034] For example, the function control module can be an application process (AP) or a host computer. The function control module may include at least one of the following: a motherboard, a central processing unit (CPU) deployed on the motherboard, peripheral interfaces, a graphics card, etc. The cellular communication module can be a cellular module. The cellular communication module can be fitted with a Subscriber Identity Module (SIM).

[0035] In this embodiment of the disclosure, the function control module is connected to the cellular communication module. For example, the function control module may include a USB interface, through which the cellular communication module can be connected to the function control module.

[0036] The function control module and the cellular communication module can exchange commands and communicate data via a USB channel. For example, the function control module can send AT commands to the cellular communication module.

[0037] For example, the function control module may include a USB interface, through which the cellular communication module can be connected to the function control module.

[0038] It should be noted that the server can be a single physical server, or a server cluster consisting of multiple servers. Alternatively, the server cluster can be a distributed cluster. Alternatively, the server can be a cloud server. This disclosure does not limit the implementation method of the server.

[0039] It should be noted that the methods in the following embodiments can all be implemented in the above-described communication system. The solutions in the embodiments of this disclosure can also be applied to other communication systems, and the corresponding names can be replaced by the names of the corresponding functions in other communication systems.

[0040] After introducing the application scenarios and implementation environments of the embodiments of this disclosure, the power consumption control method provided by the embodiments of this disclosure will be described in detail below in conjunction with the above implementation environment.

[0041] Figure 2 illustrates a power consumption control method according to an embodiment of this disclosure. This power consumption control method is applied to a cloud terminal and includes steps S201 to S203.

[0042] In S201, cloud terminal usage information is sent to the server.

[0043] The information is used to characterize the usage status of cloud terminals.

[0044] In this embodiment of the disclosure, the usage information of the cloud terminal includes at least one of the following: data transmission rate, status change indication information of the peripheral devices connected to the cloud terminal, and standby indication information. The status change indication information is used to indicate whether the usage status of the peripheral devices has changed; the standby indication information is used to indicate whether the cloud terminal is in standby mode.

[0045] The data transmission rate refers to the rate at which data is transmitted between the cloud terminal and the server. This data transmission rate may include: uplink transmission rate, and / or downlink transmission rate.

[0046] It should be noted that the embodiments disclosed herein do not limit the data transmission rate. For example, the data transmission rate can be 10 Mbps, 2 Mbps, 20 Mbps, etc.

[0047] In this embodiment of the disclosure, the status change indication information of the peripheral device connected to the cloud terminal can be either a first status information or a second status information. The first status information is used to indicate that the usage status of the peripheral device has changed, and the second status information is used to indicate that the usage status of the peripheral device has not changed.

[0048] It should be noted that the representation format of the state change indication information is not limited in the embodiments disclosed herein. For example, the state change indication information can be represented by numbers, such as 0 for the first state information and 1 for the second state information. Alternatively, the state change indication information can be represented by a letter, such as a for the first state information and b for the second state information.

[0049] It should be noted that the peripheral devices connected to the cloud terminal include, but are not limited to, at least one of the following: display screen, mouse, keyboard, etc. Alternatively, the peripheral devices connected to the cloud terminal refer to the peripheral devices included in the cloud terminal itself, such as the cloud terminal including a display screen.

[0050] In this embodiment of the disclosure, the standby indication information can be either first standby information or second standby information. The first standby information is used to indicate that the cloud terminal is not in standby mode, and the second standby information is used to indicate that the cloud terminal is in standby mode.

[0051] In one implementation, cloud terminal usage information can be sent to the server via a cellular communication module.

[0052] In S202, energy-saving control commands sent by the server are received.

[0053] In some embodiments, energy-saving control instructions are used to instruct the cloud terminal to execute a target energy-saving mode. Energy-saving control instructions sent by the server can be received via a cellular communication module.

[0054] In other words, the server can control the energy-saving mode executed by the cloud terminal.

[0055] In S203, in response to the energy-saving control command, the cellular communication module is controlled to perform energy-saving operations.

[0056] In one implementation, in response to an energy-saving control command, the energy-saving operation corresponding to the target energy-saving mode can be determined based on the target energy-saving mode and a first correspondence, and the cellular communication module can be controlled to execute the energy-saving operation. The first correspondence is the direct correspondence between energy-saving modes and energy-saving operations.

[0057] In this embodiment, the cloud terminal may further include a function control module. This function control module can send instructions to the cellular communication module to control the cellular communication module to perform energy-saving operations.

[0058] In one implementation, after receiving an energy-saving control command via the cellular communication module, the cellular communication module can send the energy-saving control command to the function control module. Then, based on the energy-saving control command, the function control module determines the energy-saving operation corresponding to the target energy-saving mode and sends a target operation command to the cellular communication module to control the cellular communication module to execute the energy-saving operation corresponding to the target energy-saving mode.

[0059] For example, if the energy-saving operation corresponding to the target energy-saving mode is to reduce the bandwidth of the cellular communication module, then the function control module controls the cellular communication module to reduce the bandwidth.

[0060] In some embodiments, in response to an energy-saving control command, the cellular communication module is controlled to perform energy-saving operations, and the function control module is controlled to perform energy-saving operations.

[0061] In other words, the energy-saving control command can simultaneously control the cellular communication module and the function control module to perform energy-saving operations, thereby reducing the power consumption of the cloud terminal.

[0062] For example, the communication bandwidth of the cellular communication module is reduced, and the CPU processing power of the function control module is reduced.

[0063] Based on the above technical solution, after sending cloud terminal usage information to the server and receiving energy-saving control commands from the server, energy-saving operations can be performed by controlling the cellular communication module. This reduces the power consumption of the cellular communication module, thereby reducing the power consumption of the cloud terminal and extending its battery life.

[0064] In some embodiments, the energy-saving control command is used to instruct the cloud terminal to execute a target energy-saving mode from among multiple energy-saving modes, and different energy-saving modes in the multiple energy-saving modes correspond to different power reductions.

[0065] For example, suppose multiple energy-saving modes include: energy-saving mode a, energy-saving mode b, and energy-saving mode c. Energy-saving mode a reduces power consumption by 0.5 watts, energy-saving mode b reduces power consumption by 2 watts, and energy-saving mode c reduces power consumption by 6 watts.

[0066] Therefore, it can be seen that different energy-saving modes in the multiple energy-saving modes correspond to different power reductions, which allows the server to control the energy-saving mode executed by the cloud terminal according to the scenario, thereby achieving a multi-level energy-saving effect.

[0067] In one implementation, the multiple energy-saving modes include at least one of the following: a first energy-saving mode, a second energy-saving mode, and a third energy-saving mode.

[0068] The first power-saving mode is used to instruct the cellular communication module to reduce communication bandwidth and / or transmit power. Communication bandwidth includes uplink bandwidth and / or downlink bandwidth, and transmit power includes uplink transmit power and / or downlink transmit power.

[0069] In other words, the first power-saving mode is used to instruct the cellular communication module to reduce the rate of data transmission.

[0070] For example, if the downlink bandwidth of the cellular communication module is 1000 Mbps, and the first power-saving mode is used to indicate reducing the communication bandwidth by 50 Mbps, then the reduced downlink bandwidth of the cellular communication module is 950 Mbps. Alternatively, if the first power-saving mode is used to indicate reducing the communication bandwidth to 200 Mbps, then the reduced downlink bandwidth of the cellular communication module is 200 Mbps.

[0071] Understandably, the first power-saving mode is used to instruct the cellular communication module to reduce communication bandwidth and / or transmission power, which can reduce power consumption by reducing the rate of data transmission.

[0072] In this embodiment of the disclosure, the second power-saving mode is used to instruct the cellular communication module to reduce communication bandwidth and / or transmit power, and the cellular communication module to reduce CPU frequency and / or shut down some CPU cores.

[0073] In other words, the second power-saving mode is used to instruct the cellular communication module to reduce the data transmission rate and reduce processing power.

[0074] For example, the second power-saving mode is used to instruct the cellular communication module to reduce communication bandwidth and reduce CPU frequency. Alternatively, the second power-saving mode is used to instruct the cellular communication module to reduce transmission power and disable some CPU cores. Alternatively, the second power-saving mode is used to instruct the cellular communication module to reduce communication bandwidth, reduce transmission power, and reduce CPU frequency and disable some CPU cores.

[0075] Understandably, the second power-saving mode is used to instruct the cellular communication module to reduce communication bandwidth and / or transmit power, and the cellular communication module to reduce the central processing unit (CPU) frequency and / or shut down some CPU cores. In other words, the second power-saving mode can reduce the data transmission rate and processing power of the cellular communication module, thereby reducing the power consumption of the cloud terminal.

[0076] Alternatively, the second power-saving mode is used to instruct the cellular communication module to reduce communication bandwidth and / or transmit power, and / or the cellular communication module to reduce CPU frequency and / or shut down some CPU cores.

[0077] In other words, the second energy-saving mode can also be used to instruct the cellular communication module to reduce the data transmission rate and / or reduce processing power.

[0078] In this embodiment of the disclosure, the third power-saving mode is used to instruct the cellular communication module to activate flight mode and disconnect the Universal Serial Bus (USB) channel connected to the cellular communication module.

[0079] For example, the third power-saving mode is used to instruct the cloud terminal to enter a deep sleep standby state. The deep sleep standby state includes: the cellular communication module activating flight mode and disconnecting the Universal Serial Bus (USB) channel connected to the cellular communication module.

[0080] In one implementation, the target pin of the control cellular communication module is set to a low level. This target pin is used to simulate the connection and disconnection of the USB channel. A low level on the target pin indicates that the USB channel is disconnected, and a high level indicates that the USB channel is connected. The control cellular communication module adjusts the USB channel to a simulated disconnected state.

[0081] For example, the cloud laptop's function control module controls an idle general-purpose input / output (GPIO) pin (e.g., GPIO pin 1) of the cellular communication module. GPIO pin 1 is associated with the Vbus_DET function of the cellular communication module, which supports USB hot-plug detection. Upon receiving a command to enter deep standby / sleep mode, the cloud laptop's function control module pulls down the level of GPIO pin 1 of the cellular communication module. Vbus_DET can then set the USB channel between the function control module and the cellular communication module to a simulated disconnected state, simulating that the cellular communication module is unplugged from the function control module's USB interface.

[0082] Understandably, airplane mode disconnects the cellular communication module from the cellular network, and disconnecting the USB channel connected to the cellular communication module disables interaction between the cellular communication module and the function control module. In other words, in the third energy-saving mode, the cellular communication module does not perform any data transmission or processing, thereby reducing power consumption.

[0083] In some embodiments, after the cloud terminal enters the target power-saving mode, it can send mode activation information to the server. This mode activation information is used to indicate that the cloud terminal has entered the target power-saving mode.

[0084] The process of the server issuing energy-saving control commands to the cloud terminal is described below. Figure 3 shows a power consumption control method according to an embodiment of this disclosure. This power consumption control method includes steps S301 and S302.

[0085] In S301, the usage information of the cloud terminal sent by the cloud terminal is received.

[0086] The information is used to characterize the usage status of cloud terminals.

[0087] In S302, energy-saving control commands are sent to the cloud terminal based on the cloud terminal's usage information.

[0088] Energy-saving control commands are used to instruct the cellular communication module of the cloud terminal to perform energy-saving operations.

[0089] In one implementation, based on the cloud terminal's usage information, the energy-saving operation to be performed by the cloud terminal can be determined. Then, an energy-saving control command is sent to the cloud terminal.

[0090] For example, if the cloud terminal's usage information includes a downlink data transmission rate of 50 Mbps and a downlink bandwidth of 500 Mbps, then the cloud terminal can determine that the energy-saving operation is to reduce the downlink bandwidth.

[0091] Based on the above technical solution, the system receives usage information from the cloud terminal and sends energy-saving control commands to the cloud terminal to control its cellular communication module to perform energy-saving operations. This reduces the power consumption of the cellular communication module, thereby reducing the power consumption of the cloud terminal and extending its battery life.

[0092] In some embodiments, based on the cloud terminal's usage information, a target energy-saving mode to be executed by the cloud terminal can be determined from multiple energy-saving modes. Then, an energy-saving control command is sent to the cloud terminal, which instructs the cloud terminal to execute the target energy-saving mode from among the multiple energy-saving modes.

[0093] The following section uses at least one of multiple energy-saving modes, including the first energy-saving mode, the second energy-saving mode, and the third energy-saving mode, as an example to introduce the process of determining the target energy-saving mode to be executed by the cloud terminal based on the usage information of the cloud terminal.

[0094] In one implementation, when the data transmission rate in the information being used is less than or equal to a preset rate threshold, the energy-saving control command is used to indicate that the target energy-saving mode is the first energy-saving mode.

[0095] In this embodiment of the disclosure, the data transmission rate can be the average rate within a preset duration (such as 1 second, 30 seconds, 60 seconds, etc.).

[0096] It should be noted that the preset rate threshold is not limited in the embodiments disclosed herein. For example, the preset rate threshold can be 20 Mbps, 10 Mbps, 5 Mbps, etc. This preset rate threshold can be configured by the developer or the user.

[0097] For example, as shown in Figure 4, in S401, the cloud server can monitor the data transmission rate of the cloud laptop; in S402, when the data transmission rate of the cloud laptop is less than a preset rate threshold, the cloud server sends an instruction to the cloud laptop to enter the first power-saving mode; in S403, after receiving the instruction to enter the first power-saving mode, the cloud laptop can send an instruction to the cellular communication module to reduce the communication bandwidth through the function control module, and control the cellular communication module to reduce the communication bandwidth.

[0098] It's understandable that if the data transmission rate is less than or equal to a preset threshold, it indicates that the cloud terminal's current data transmission needs are relatively low. Therefore, power consumption can be reduced while ensuring data transmission requirements are met by decreasing bandwidth or transmission power.

[0099] In one implementation, when the status change indication information of each peripheral device in the usage information indicates that the status of the peripheral device has not changed, the energy-saving control instruction is used to indicate that the target energy-saving mode is the second energy-saving mode.

[0100] For example, as shown in Figure 5, in S501, the cloud laptop can monitor the screen's state change indication information (i.e., whether the screen has changed), the keyboard's state change indication information (whether the keyboard has generated an event input), and the mouse's state change indication information (whether the mouse has generated an event input), and upload the monitored information to the cloud server; then, in S502, if the screen does not change and there are no mouse or keyboard events within a preset time, the cloud server sends an instruction to the cloud laptop to enter the second power-saving mode; in S503, after receiving the instruction to enter the second power-saving mode, the function control module can send instructions to the cellular communication module to reduce communication bandwidth, reduce CPU frequency, and shut down a certain CPU core.

[0101] Alternatively, after monitoring the status changes of the screen, keyboard, and mouse, the cloud laptop determines that there are no changes on the screen or any mouse or keyboard events within a preset time period, and then enters the second power-saving mode.

[0102] It is understandable that if the status change indications of each peripheral device show no change in the peripheral device's status, it means the user has not operated the cloud terminal to execute business events. Therefore, power consumption can be reduced by decreasing the transmission rate and processing power of the cellular communication module.

[0103] In one implementation, when the data transmission rate in the usage information is less than or equal to a preset rate threshold, and the status change indication information of each peripheral device indicates that the status of the peripheral device has not changed, the energy-saving control command is used to indicate that the target energy-saving mode is the third energy-saving mode.

[0104] For example, as shown in Figure 6, the cloud server can monitor the data transmission rate of the cloud laptop. For instance, as described in Figure 6, in S601, the cloud laptop can monitor screen state change indicators (i.e., whether the screen changes), keyboard state change indicators (whether a keyboard event occurs), and mouse state change indicators (whether a mouse event occurs), and upload the monitored information to the cloud server. Then, in S602, if within a preset time period there is no screen change, no mouse event, no keyboard event input, and the data transmission rate is less than a preset rate threshold, the cloud server sends a command to the cloud laptop to enter the third power-saving mode. In S603, after receiving the command to enter the third power-saving mode, the cloud laptop's function control module pulls down the level of GPIO pin 1 of the cellular communication module. Vbus_DET can set the USB channel between the function control module and the cellular communication module to a simulated disconnected state, i.e., simulate the cellular communication module being unplugged from the function control module's USB interface. Furthermore, the cellular communication module can generate an AT (Attention) command to enter airplane mode.

[0105] In one implementation, when the standby indication information in the usage information indicates that the cloud terminal is in standby mode, the energy-saving control command is used to indicate that the target energy-saving mode is the third energy-saving mode.

[0106] For example, the cloud terminal detects the user's operation of the standby key and sends a second standby information to the cloud server. Then, the cloud server can send a command to the cloud terminal to enter a third power-saving mode. Alternatively, the cloud terminal can detect the user's operation of the standby key and generate a command to enter the third power-saving mode.

[0107] Understandably, when data transmission rates are low and the user is not operating the cloud terminal, activating airplane mode and disconnecting the USB channel connected to the cellular communication module disconnects the cellular communication module from the cellular network, thus preventing interaction between the cellular communication module and the function control module. In other words, in the third energy-saving mode, the cellular communication module does not perform any data transmission or processing, thereby reducing power consumption.

[0108] In another implementation, when the cloud terminal is in the first energy-saving mode, the status change indication information of each peripheral device in the usage information indicates that the status of the peripheral device has not changed, and the energy-saving control command is used to indicate that the target energy-saving mode is the third energy-saving mode.

[0109] In other words, cloud terminals can be upgraded from the first energy-saving mode to the third energy-saving mode.

[0110] In another implementation, when the cloud terminal is in the second energy-saving mode, the data transmission rate in the information is less than or equal to a preset rate threshold, and the energy-saving control command is used to indicate that the target energy-saving mode is the third energy-saving mode.

[0111] In other words, cloud terminals can be upgraded from the second energy-saving mode to the third energy-saving mode.

[0112] In some embodiments, the cloud terminal does not need to send usage information; the server can directly send energy-saving control commands to the cloud terminal.

[0113] For example, the server can directly send energy-saving control instructions to the cloud terminal to execute the third energy-saving mode.

[0114] In other embodiments, the cloud terminal can determine the target energy-saving mode based on usage information and execute the energy-saving operation corresponding to the target energy-saving mode.

[0115] For example, the server can determine the energy-saving operation corresponding to the third energy-saving mode based on usage information.

[0116] In some embodiments, the cloud terminal can receive an automatic energy-saving operation from a user. This automatic energy-saving operation is used to instruct the cloud terminal to automatically enter energy-saving mode. When the cloud terminal is in automatic energy-saving mode, it can execute the energy-saving operation corresponding to the target energy-saving mode based on energy-saving control instructions.

[0117] In other words, users can control whether the cloud terminal automatically enters energy-saving mode, thereby reducing the cloud terminal's response capacity and power consumption.

[0118] In other embodiments, when the cloud terminal is in the target energy-saving mode, updated usage information (i.e., usage information when in the target energy-saving mode) can be obtained. If the updated usage information meets preset conditions, the target energy-saving mode can be exited.

[0119] The preset conditions may include at least one of the following: the data transmission rate in the updated usage information is greater than a preset rate threshold; the status change indication information of at least one peripheral device in the updated usage information is used to indicate that the status of the peripheral device has changed; and the standby indication information in the updated usage information indicates that the cloud terminal is in a non-standby state.

[0120] For example, if the cloud laptop is in the first power-saving mode and the updated data transmission rate exceeds a preset rate threshold, the cloud server can send a command to the cloud laptop to remove the bandwidth limit. The cloud laptop's function control module sends the AT command to remove the bandwidth limit to the cellular communication module via the USB channel.

[0121] Alternatively, if the cloud laptop is in the second power-saving mode, when the cloud laptop detects keyboard input, and / or mouse input, and / or screen changes, the cloud laptop's function control module sends commands to the cellular communication module via the USB channel to increase antenna transmission power, increase CPU frequency, and disable CPU cores.

[0122] Alternatively, if the cloud laptop is in the third power-saving mode, when it detects keyboard input, / or mouse input, / or screen changes, / or data transfer rates exceeding a preset threshold, the cloud laptop's function control module sends an exit deep standby hibernation command to the cellular module. The function control module also pulls high the GPIO pin of the cellular communication module. Vbus_DET can then set the USB channel between the function control module and the cellular communication module to a simulated connection state, simulating the cellular communication module being plugged into the function control module's USB interface. Furthermore, the cellular communication module can generate an AT command to exit airplane mode.
