It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads).

[0024] The following embodiments describe a terminal including a display and a touch-sensitive surface. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.

[0025] The chip control method provided in this application embodiment can be executed by an electronic device or a functional module or entity in an electronic device that can implement the chip control method. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablets, computers, cameras, and wearable devices. The chip control method provided in this application embodiment will be described below using an electronic device as the execution subject.

[0026] like Figure 1 As shown, the chip control method is applied to a target chip, which includes a main control unit, a power management unit, a first communication unit, and a second communication unit; the chip control method includes steps 110 and 120.

[0027] Step 110: When the target chip is in sleep mode and the target wake-up conditions are met, the main control unit sends a target wake-up command to the power management unit to control the power management unit to wake up the first communication unit and / or the second communication unit; the first communication unit is used to process broadband communication services, and the second communication unit is used to process narrowband communication services.

[0028] In actual implementation, the target chip can be a chip in the power grid field, deployed on any network node for data transmission, or a chip in any field. This application does not impose any specific restrictions on this.

[0029] In actual execution, the target wake-up condition can be the prerequisite for activating the first communication unit and / or the second communication unit, so that the first communication unit and / or the second communication unit are in a listening state.

[0030] In actual implementation, the power management unit is the core of power control in the target chip and is never powered off. It can include a power management unit (PMU), a low-power real-time clock (RTC), and key logic for power and clock control.

[0031] In actual execution, the main control unit includes the main processor (such as a RISC-V MCU), shared memory, and system peripherals, and its power state is dynamically adjusted according to the overall task requirements of the target chip.

[0032] In actual implementation, the first communication unit can be used to handle broadband communication services with high-speed, high-data-volume communication protocols, such as WiFi communication services. The second communication unit is used to handle narrowband communication services, such as BLE communication services.

[0033] In actual implementation, the first communication unit may include a first processor, MAC layer logic, and a high-speed PHY interface. The power supply of the first communication unit can be independently controlled by the power management unit.

[0034] In actual implementation, the second communication unit may include a second processor, MAC layer logic, and a high-speed PHY interface. The power supply of the second communication unit can be independently controlled by the power management unit to avoid unnecessary power consumption.

[0035] In some embodiments, the power management unit wakes up the first communication unit upon receiving a broadband communication task or upon reaching a wake-up time for the first communication unit.

[0036] In some embodiments, the power management unit wakes up the second communication unit upon receiving a narrowband communication task or upon reaching a wake-up time for the second communication unit.

[0037] Step 120: Based on the collaborative control strategy, control the first communication unit and / or the second communication unit to operate collaboratively.

[0038] In actual implementation, the main control unit and the power management unit can precisely control the power supply of the first communication unit and the second communication unit based on a cooperative control strategy, so as to control the first communication unit and the second communication unit to operate in coordination.

[0039] In some embodiments, the main control unit and the power management unit may, based on a cooperative control strategy, turn off the power supply to the second communication unit and supply power only to the first communication unit, so that the first communication unit can listen to or process broadband communication tasks; or the main control unit and the power management unit may, based on a cooperative control strategy, turn off the power supply to the first communication unit and supply power only to the second communication unit, so that the second communication unit can listen to or process narrowband communication tasks.

[0040] In some embodiments, the main control unit can control the target chip to enter a sleep state if no broadband communication task or narrowband communication task is received within a predetermined time period.

[0041] According to the chip control method of this application embodiment, when the target chip is in a sleep state and the target wake-up conditions are met, the main control unit sends a target wake-up command to the power management unit; the power management unit wakes up the first communication unit and / or the second communication unit based on the target wake-up command; the first communication unit is used to process broadband communication services, and the second communication unit is used to process narrowband communication services; based on a cooperative control strategy, the first communication unit and / or the second communication unit are controlled to operate in coordination, so that the target chip can process broadband communication services and narrowband communication services in coordination through the first communication unit and the second communication unit, avoiding unnecessary power consumption generated by relying on the first communication unit, which has the capability to process broadband communication services, to process narrowband communication services.

[0042] In some embodiments, the sleep state includes a first sleep state; after controlling the first communication unit and / or the second communication unit to operate collaboratively based on a collaborative control strategy, if the first communication unit completes the processing of a broadband communication task and no broadband or narrowband communication task is received within a first preset time, the main control unit sends a first sleep instruction to the power management unit; the power management unit shuts down the power supply of the first communication unit based on the first sleep instruction, so as to control the target chip to enter the first sleep state.

[0043] In actual execution, the first sleep state means that the target chip is in a shallow sleep state that keeps the power on. The target chip's central processing unit is suspended, but the power supply to the central processing unit and memory (SRAM) is maintained to achieve fast wake-up and no data loss.

[0044] In actual execution, the first preset time can be a pre-set time length. For example, the first preset time can be a time length set based on actual experiments, with the goal of minimizing the power consumption of the target chip.

[0045] In some embodiments, the main control unit may acquire a first preset time.

[0046] In some embodiments, after the first communication unit completes the processing of the broadband communication task, the main control unit detects whether there are any broadband communication tasks and narrowband communication tasks waiting to be processed. If there are no broadband communication tasks and narrowband communication tasks waiting to be processed, and no broadband communication task or narrowband communication task is received within a first preset time, the main control unit generates a first sleep instruction and sends the first sleep instruction to the power management unit.

[0047] In some embodiments, after receiving a first sleep command, the power management unit stops supplying power to the first communication unit, and if no broadband or narrowband communication task is received within a first preset time, controls the target chip to enter a first sleep state. For example, if no broadband or narrowband communication task is received within 10 minutes, the power management unit controls the target chip to enter a first sleep state.

[0048] According to the chip control method of this application embodiment, when the target chip is in a sleep state and the target wake-up condition is met, the main control unit sends a target wake-up command to the power management unit; the power management unit wakes up the first communication unit and / or the second communication unit based on the target wake-up command; the first communication unit is used to process broadband communication services, and the second communication unit is used to process narrowband communication services; based on a cooperative control strategy, the first communication unit and / or the second communication unit are controlled to operate cooperatively; when the first communication unit completes the processing of the broadband communication task and no broadband communication task or narrowband communication task is received within a first preset time, the main control unit sends a first sleep command to the power management unit; the power management unit turns off the power of the first communication unit based on the first sleep command, so as to control the target chip to enter the first sleep state, so that the target chip enters the first sleep state when there is no communication task processing, thereby reducing unnecessary power consumption.

[0049] In some embodiments, the sleep state includes a second sleep state; the first sleep instruction includes a second preset time, which is the duration for which the target chip remains in the first sleep state; after the power management unit shuts down the power of the first communication unit based on the first sleep instruction to control the target chip to enter the first sleep state, and the target chip is in the first sleep state and no broadband communication task or narrowband communication task is received within the second preset time, the main control unit sends a second sleep instruction to the power management unit; the power management unit controls the target chip to enter the second sleep state based on the second sleep instruction.

[0050] In actual execution, the second sleep state means that the power supply to both the first and second communication units of the target chip is turned off, and the power management unit only maintains the real-time clock and AON logic function.

[0051] In actual execution, the second preset time can be a pre-set time length. For example, the second preset time can be a time length set based on actual experiments, with the goal of minimizing the power consumption of the target chip.

[0052] In some embodiments, after the target chip enters a first sleep state, if no broadband communication task or narrowband communication task is received within a second preset time, the main control unit generates a second sleep instruction and sends the second sleep instruction to the power management unit.

[0053] In some embodiments, after the target chip enters a first sleep state, if no broadband communication task or narrowband communication task is received within a second preset time, the main control unit may calculate the time when the first communication unit is in a closed state and the time when the second communication unit is in a closed state, and generate a second sleep instruction based on the time when the first communication unit is in a closed state and the time when the second communication unit is in a closed state.

[0054] In some embodiments, after receiving the second sleep command, the power management unit shuts down the power supply of the main control unit, the first communication unit, and the second communication unit based on the second sleep command, so as to control the target chip to enter the second sleep state.

[0055] In some embodiments, when the second communication unit completes the processing of the narrowband communication task and no broadband or narrowband communication task is currently received, the power supply of the first communication unit has been turned off, and the main control unit sends a third sleep instruction to the power management unit; based on the third sleep instruction, the power management unit turns off the power supply of the second communication unit to control the target chip to enter the second sleep state.

[0056] According to the chip control method of this application embodiment, when the target chip is in a sleep state and the target wake-up condition is met, the main control unit sends a target wake-up command to the power management unit; the power management unit wakes up the first communication unit and / or the second communication unit based on the target wake-up command; the first communication unit is used to process broadband communication services, and the second communication unit is used to process narrowband communication services; based on a cooperative control strategy, the first communication unit and / or the second communication unit are controlled to operate cooperatively. When the target chip is in a first sleep state and no broadband communication task or narrowband communication task is received within a second preset time, the main control unit sends a second sleep command to the power management unit; the power management unit controls the target chip to enter the second sleep state based on the second sleep command, so that the target chip enters a deep sleep state when there is no communication task processing, thereby reducing unnecessary power consumption.

[0057] In some embodiments, the second sleep instruction includes a third preset time and a fourth preset time; after the power management unit controls the target chip to enter the second sleep state based on the second sleep instruction, when the target chip is in the second sleep state and the timing value for the first communication unit is greater than or equal to the third preset time, the power management unit turns on the power of the first communication unit; and / or, when the target chip is in the second sleep state and the timing value for the second communication unit is greater than or equal to the fourth preset time, the power management unit turns on the power of the second communication unit.

[0058] In actual execution, the third preset time is the length of time the target chip periodically wakes up the first communication unit from the second sleep state. The fourth preset time is the length of time the target chip periodically wakes up the second communication unit from the second sleep state.

[0059] In some embodiments, the main control unit can obtain a third preset time and a fourth preset time based on historical communication duration and a preset communication period. For example, the main control unit can obtain the third preset time based on a first historical synchronization time point of the target chip and a preset communication period, where the first historical synchronization time point is the historical synchronization time point of broadband communication between the first communication unit in the target chip and the network. For example, the main control unit can obtain the fourth preset time based on a second historical synchronization time point of the target chip and a preset communication period, where the second historical synchronization time point is the historical synchronization time point of narrowband communication between the second communication unit in the target chip and the network.

[0060] In some embodiments, after the target chip enters a second sleep state, the power management unit can time the sleep state of the first communication unit based on a real-time clock. If the time value for the first communication unit is greater than or equal to a third preset time, the power management unit turns on the power to the first communication unit.

[0061] In some embodiments, after the target chip enters a second sleep state, the power management unit can time the sleep state of the second communication unit based on a real-time clock. If the time value for the second communication unit is greater than or equal to a fourth preset time, the power management unit turns on the power to the second communication unit.

[0062] According to the chip control method of this application embodiment, when the target chip is in a sleep state and the target wake-up conditions are met, the main control unit sends a target wake-up command to the power management unit; the power management unit wakes up the first communication unit and / or the second communication unit based on the target wake-up command; the first communication unit is used to process broadband communication services, and the second communication unit is used to process narrowband communication services; based on a cooperative control strategy, the first communication unit and / or the second communication unit are controlled to operate in coordination, so that the target chip can process broadband communication services and narrowband communication services in coordination through the first communication unit and the second communication unit, avoiding unnecessary power consumption generated by relying on the first communication unit, which has the capability to process broadband communication services, to process narrowband communication services.

[0063] In some embodiments, when the target chip is in a sleep state and receives a broadband communication task, the main control unit sends a first wake-up command to the power management unit to enable the power management unit to power on the first communication unit; and / or when the target chip is in a sleep state and receives a narrowband communication task, the main control unit sends a second wake-up command to the power management unit to enable the power management unit to power on the second communication unit.

[0064] In actual execution, the target wake-up instruction may include a first wake-up instruction and a second wake-up instruction.

[0065] In some embodiments, when the target chip is in a first sleep state or a second sleep state and receives a broadband communication task, the main control unit generates a first wake-up command for waking up the first communication unit and sends the first wake-up command to the power management unit. After receiving the first wake-up command, the power management unit turns on the power of the first communication unit based on the first wake-up command, so that the first communication unit listens for and processes the broadband communication task.

[0066] In some embodiments, when the target chip is in a first sleep state or a second sleep state and receives a narrowband communication task, the main control unit generates a second wake-up command for waking up the second communication unit and sends the second wake-up command to the power management unit. After receiving the second wake-up command, the power management unit turns on the power of the second communication unit based on the second wake-up command, so that the second communication unit listens for and processes the narrowband communication task.

[0067] According to the chip control method of this application embodiment, when the target chip is in a sleep state and the target wake-up conditions are met, the main control unit sends a target wake-up command to the power management unit; the power management unit wakes up the first communication unit and / or the second communication unit based on the target wake-up command; the first communication unit is used to process broadband communication services, and the second communication unit is used to process narrowband communication services; based on a cooperative control strategy, the first communication unit and / or the second communication unit are controlled to operate in coordination, so that the target chip can process broadband communication services and narrowband communication services in coordination through the first communication unit and the second communication unit, avoiding unnecessary power consumption generated by relying on the first communication unit, which has the capability to process broadband communication services, to process narrowband communication services.

[0068] In some embodiments, when the first communication unit is processing a broadband communication task and receives a narrowband communication task, the main control unit determines the priorities of the broadband communication task and the narrowband communication task; when the priority of the broadband communication task is lower than the priority of the narrowband communication task, the main control unit sends a first mode switching instruction to the power management unit; the first mode switching instruction is used to instruct the first communication unit to suspend the processing of the broadband communication task and the second communication unit to start the processing of the narrowband communication task; based on the first mode switching instruction, the power management unit turns off the power of the first communication unit and turns on the power of the second communication unit.

[0069] In some embodiments, when the priority of the broadband communication task is lower than that of the narrowband communication task, the main control unit generates a first mode switching instruction and sends it to the power management unit. Based on the first mode switching instruction, the power management unit shuts down the power of the first communication unit to suspend the processing of the broadband communication task and turns on the power of the second communication unit to start the processing of the narrowband communication task. After the second communication unit completes the processing of the narrowband communication task, the power management unit shuts down the power of the second communication unit and turns on the power of the first communication unit to continue the processing of the broadband communication task.

[0070] In some embodiments, when the first communication unit is processing a broadband communication task and receives a narrowband communication task, the main control unit determines the priorities of the broadband communication task and the narrowband communication task. If the priority of the broadband communication task is higher than that of the narrowband communication task, the main control unit sends a third mode switching instruction to the power management unit. Based on the third mode switching instruction, the power management unit instructs the first communication unit to continue processing the broadband communication task. After the first communication unit completes processing the broadband communication task, the power supply of the first communication unit is turned off, and the power supply of the second communication unit is turned on to start processing the narrowband communication task.

[0071] In some embodiments, when the first communication unit is processing a broadband communication task and receives another broadband communication task, after the first communication unit finishes processing the current broadband communication task, it continues to process the next broadband communication task until no broadband communication task is detected.

[0072] According to the chip control method of this application embodiment, when the target chip is in a sleep state and the target wake-up conditions are met, the power management unit wakes up the first communication unit and / or the second communication unit. The first communication unit is used to process broadband communication services, and the second communication unit is used to process narrowband communication services. When the first communication unit is processing a broadband communication task and receives a narrowband communication task, after the first communication unit completes processing the broadband communication task, the first communication unit is turned off, and the second communication unit is scheduled to process the narrowband communication task. This allows the target chip to collaboratively process broadband and narrowband communication services through the first and second communication units, avoiding unnecessary power consumption caused by relying on the first communication unit, which has the capability to process broadband communication services, to process narrowband communication services. Furthermore, the time-slot-based collaborative management method can flexibly cope with complex mixed service scenarios in power sensor networks, avoid communication conflicts, and ensure the reliability of data transmission.

[0073] In some embodiments, when the second communication unit is processing a narrowband communication task and receives a broadband communication task, the main control unit determines the priority of the broadband communication task and the narrowband communication task; when the priority of the narrowband communication task is lower than the priority of the broadband communication task, the main control unit sends a second mode switching instruction to the power management unit; the second mode switching instruction is used to instruct the second communication unit to suspend the processing of the narrowband communication task and the first communication unit to start the processing of the broadband communication task; based on the second mode switching instruction, the power management unit turns off the power of the second communication unit and turns on the power of the first communication unit.

[0074] In some embodiments, when the priority of the broadband communication task is higher than that of the narrowband communication task, the main control unit generates a second mode switching instruction and sends it to the power management unit. Based on the second mode switching instruction, the power management unit shuts down the power of the second communication unit to suspend the processing of the narrowband communication task and turns on the power of the first communication unit to start the processing of the broadband communication task. After the first communication unit completes the processing of the broadband communication task, the power management unit shuts down the power of the first communication unit and turns on the power of the second communication unit to continue the processing of the narrowband communication task.

[0075] In some embodiments, when the second communication unit is processing a narrowband communication task and receives a broadband communication task, the main control unit determines the priority of the broadband communication task and the narrowband communication task. If the priority of the narrowband communication task is higher than that of the broadband communication task, the main control unit sends a fourth mode switching instruction to the power management unit. Based on the fourth mode switching instruction, the power management unit instructs the second communication unit to continue processing the narrowband communication task. After the second communication unit completes processing the narrowband communication task, the power supply of the second communication unit is turned off, and the power supply of the first communication unit is turned on to start processing the broadband communication task.

[0076] In some embodiments, when the second communication unit is processing a narrowband communication task and receives another narrowband communication task, after the second communication unit finishes processing the current narrowband communication task, it continues to process the next narrowband communication task until no narrowband communication task is detected.

[0077] According to the chip control method of this application embodiment, when the target chip is in a sleep state and the target wake-up conditions are met, the power management unit wakes up the first communication unit and / or the second communication unit. The first communication unit is used to process broadband communication services, and the second communication unit is used to process narrowband communication services. When the second communication unit is processing a narrowband communication task and receives a broadband communication task, after the second communication unit completes the processing of the narrowband communication task, the second communication unit is turned off, and the first communication unit is scheduled to process the broadband communication task. This allows the target chip to collaboratively process broadband and narrowband communication services through the first and second communication units, avoiding unnecessary power consumption caused by relying on the first communication unit, which has the capability to process broadband communication services, to process narrowband communication services. Furthermore, the time-slot-based collaborative management method can flexibly cope with complex mixed service scenarios in power sensor networks, avoid communication conflicts, and ensure the reliability of data transmission.

[0078] To better understand the chip control method provided in the embodiments of this application, further explanation is provided below. It should be understood that the following discussion is merely exemplary.

[0079] This application provides a chip control method, the specific steps of which are as follows: Figure 2 As shown: Step 210: When the target chip is in sleep mode and receives a broadband communication task, the main control unit sends a first wake-up command to the power management unit; the power management unit, based on the first wake-up command, enables the power management unit to turn on the power of the first communication unit; and / or when the target chip is in sleep mode and receives a narrowband communication task, the main control unit sends a second wake-up command to the power management unit to enable the power management unit to turn on the power of the second communication unit.

[0080] In actual implementation, the target chip can be a chip in the power grid field, deployed on any network node for data transmission, or a chip in any field. This application does not impose any specific restrictions on this.

[0081] In actual execution, the target wake-up condition can be the prerequisite for activating the first communication unit and / or the second communication unit, so that the first communication unit and / or the second communication unit are in a listening state.

[0082] In actual implementation, the first communication unit can be used to handle broadband communication services with high-speed, high-data-volume communication protocols, such as WiFi communication services. The second communication unit is used to handle narrowband communication services, such as BLE communication services.

[0083] In actual implementation, the power management unit is the core of power control in the target chip and is never powered off. It can include a power management unit (PMU), a low-power real-time clock (RTC), and key logic for power and clock control.

[0084] In actual implementation, the first communication unit may include a first processor, MAC layer logic, and a high-speed PHY interface. The power supply of the first communication unit can be independently controlled by the power management unit.

[0085] In actual implementation, the second communication unit may include a second processor, MAC layer logic, and a high-speed PHY interface. The power supply of the second communication unit can be independently controlled by the power management unit to avoid unnecessary power consumption.

[0086] In some embodiments, when the target chip is in a first sleep state or a second sleep state and receives a broadband communication task, the main control unit generates a first wake-up command for waking up the first communication unit and sends the first wake-up command to the power management unit. After receiving the first wake-up command, the power management unit turns on the power of the first communication unit based on the first wake-up command, so that the first communication unit listens for and processes the broadband communication task.

[0087] In some embodiments, when the target chip is in a first sleep state or a second sleep state and receives a narrowband communication task, the main control unit generates a second wake-up command for waking up the second communication unit and sends the second wake-up command to the power management unit. After receiving the second wake-up command, the power management unit turns on the power of the second communication unit based on the second wake-up command, so that the second communication unit listens for and processes the narrowband communication task.

[0088] Step 220: When the first communication unit is processing a broadband communication task and receives a narrowband communication task, the main control unit determines the priority of the broadband communication task and the narrowband communication task. When the priority of the broadband communication task is lower than that of the narrowband communication task, the main control unit sends a first mode switching instruction to the power management unit. The first mode switching instruction is used to instruct the first communication unit to suspend the processing of the broadband communication task and the second communication unit to start the processing of the narrowband communication task. Based on the first mode switching instruction, the power management unit turns off the power of the first communication unit and turns on the power of the second communication unit.

[0089] In some embodiments, when the priority of a broadband communication task is lower than that of a narrowband communication task, the main control unit generates a first mode switching instruction and sends the first mode switching instruction to the power management unit. For example... Figure 3 As shown, based on the first mode switching instruction, the power management unit shuts down the power of the first communication unit to suspend the processing of the broadband communication task, and turns on the power of the second communication unit to start the processing of the narrowband communication task. After the second communication unit completes the processing of the narrowband communication task, the power management unit shuts down the power of the second communication unit and turns on the power of the first communication unit to continue the processing of the broadband communication task.

[0090] In some embodiments, when the first communication unit is processing a broadband communication task and receives a narrowband communication task, the main control unit determines the priorities of the broadband communication task and the narrowband communication task. If the priority of the broadband communication task is higher than that of the narrowband communication task, the main control unit sends a third mode switching instruction to the power management unit. Based on the third mode switching instruction, the power management unit instructs the first communication unit to continue processing the broadband communication task. After the first communication unit completes processing the broadband communication task, the power supply of the first communication unit is turned off, and the power supply of the second communication unit is turned on to start processing the narrowband communication task.

[0091] In some embodiments, when the first communication unit is processing a broadband communication task and receives another broadband communication task, after the first communication unit finishes processing the current broadband communication task, it continues to process the next broadband communication task until no broadband communication task is detected.

[0092] In some embodiments, when the second communication unit completes the processing of the narrowband communication task and no broadband or narrowband communication task is currently received, the power supply of the first communication unit has been turned off, and the main control unit sends a third sleep instruction to the power management unit; based on the third sleep instruction, the power management unit turns off the power supply of the second communication unit to control the target chip to enter the second sleep state.

[0093] Step 230: When the second communication unit is processing a narrowband communication task and receives a broadband communication task, the main control unit determines the priority of the broadband communication task and the narrowband communication task. If the priority of the narrowband communication task is lower than that of the broadband communication task, the main control unit sends a second mode switching instruction to the power management unit. The second mode switching instruction is used to instruct the second communication unit to suspend the processing of the narrowband communication task and the first communication unit to start the processing of the broadband communication task. Based on the second mode switching instruction, the power management unit turns off the power of the second communication unit and turns on the power of the first communication unit.

[0094] In some embodiments, when the priority of the broadband communication task is higher than that of the narrowband communication task, the main control unit generates a second mode switching instruction and sends it to the power management unit. Based on the second mode switching instruction, the power management unit shuts down the power of the second communication unit to suspend the processing of the narrowband communication task and turns on the power of the first communication unit to start the processing of the broadband communication task. After the first communication unit completes the processing of the broadband communication task, the power management unit shuts down the power of the first communication unit and turns on the power of the second communication unit to continue the processing of the narrowband communication task.

[0095] In some embodiments, when the second communication unit is processing a narrowband communication task and receives a broadband communication task, the main control unit determines the priority of the broadband communication task and the narrowband communication task. If the priority of the narrowband communication task is higher than that of the broadband communication task, the main control unit sends a fourth mode switching instruction to the power management unit. Based on the fourth mode switching instruction, the power management unit instructs the second communication unit to continue processing the narrowband communication task. After the second communication unit completes processing the narrowband communication task, the power supply of the second communication unit is turned off, and the power supply of the first communication unit is turned on to start processing the broadband communication task.

[0096] In some embodiments, when the second communication unit is processing a narrowband communication task and receives another narrowband communication task, after the second communication unit finishes processing the current narrowband communication task, it continues to process the next narrowband communication task until no narrowband communication task is detected.

[0097] Step 240: If the first communication unit completes the processing of the broadband communication task and no broadband or narrowband communication task is received within a first preset time, the main control unit sends a first sleep command to the power management unit; based on the first sleep command, the power management unit turns off the power of the first communication unit to control the target chip to enter the first sleep state.

[0098] In actual execution, the first sleep state means that the target chip is in a shallow sleep state that keeps the power on. The target chip's central processing unit is suspended, but the power supply to the central processing unit and memory (SRAM) is maintained to achieve fast wake-up and no data loss.

[0099] In actual execution, the first preset time can be a pre-set time length. For example, the first preset time can be a time length set based on actual experiments, with the goal of minimizing the power consumption of the target chip.

[0100] In some embodiments, the main control unit may acquire a first preset time.

[0101] In some embodiments, after the first communication unit completes the processing of the broadband communication task, the main control unit detects whether there are any broadband communication tasks and narrowband communication tasks waiting to be processed. If there are no broadband communication tasks and narrowband communication tasks waiting to be processed, and no broadband communication task or narrowband communication task is received within a first preset time, the main control unit generates a first sleep instruction and sends the first sleep instruction to the power management unit.

[0102] In some embodiments, after receiving a first sleep command, the power management unit stops supplying power to the first communication unit, and if no broadband or narrowband communication task is received within a first preset time, controls the target chip to enter a first sleep state. For example, if no broadband or narrowband communication task is received within 10 minutes, the power management unit controls the target chip to enter a first sleep state.

[0103] Step 250: When the target chip is in the first sleep state and no broadband communication task or narrowband communication task is received within the second preset time, the main control unit sends a second sleep command to the power management unit; the power management unit controls the target chip to enter the second sleep state based on the second sleep command.

[0104] In actual execution, the second sleep state means that the power supply to both the first and second communication units of the target chip is turned off, and the power management unit only maintains the real-time clock and AON logic function.

[0105] In actual execution, the second preset time can be a pre-set time length. For example, the second preset time can be a time length set based on actual experiments, with the goal of minimizing the power consumption of the target chip.

[0106] In some embodiments, after the target chip enters a first sleep state, if no broadband communication task or narrowband communication task is received within a second preset time, the main control unit generates a second sleep instruction and sends the second sleep instruction to the power management unit.

[0107] In some embodiments, after the target chip enters a first sleep state, if no broadband communication task or narrowband communication task is received within a second preset time, the main control unit may calculate the time when the first communication unit is in a closed state and the time when the second communication unit is in a closed state, and generate a second sleep instruction based on the time when the first communication unit is in a closed state and the time when the second communication unit is in a closed state.

[0108] In some embodiments, after receiving the second sleep command, the power management unit shuts down the power supply of the main control unit, the first communication unit, and the second communication unit based on the second sleep command, so as to control the target chip to enter the second sleep state.

[0109] Step 260: When the target chip is in a second sleep state and the timing value for the first communication unit is greater than or equal to a third preset time, the power management unit turns on the power of the first communication unit; and / or, when the target chip is in a second sleep state and the timing value for the second communication unit is greater than or equal to a fourth preset time, the power management unit turns on the power of the second communication unit.

[0110] In some embodiments, the main control unit can obtain a third preset time and a fourth preset time based on historical communication duration and a preset communication period. For example, the main control unit can obtain the third preset time based on a first historical synchronization time point of the target chip and a preset communication period, where the first historical synchronization time point is the historical synchronization time point of broadband communication between the first communication unit in the target chip and the network. For example, the main control unit can obtain the fourth preset time based on a second historical synchronization time point of the target chip and a preset communication period, where the second historical synchronization time point is the historical synchronization time point of narrowband communication between the second communication unit in the target chip and the network.

[0111] In some embodiments, after the target chip enters a second sleep state, the power management unit can time the sleep state of the first communication unit based on a real-time clock. If the time value for the first communication unit is greater than or equal to a third preset time, the power management unit turns on the power to the first communication unit.

[0112] In some embodiments, after the target chip enters a second sleep state, the power management unit can time the sleep state of the second communication unit based on a real-time clock. If the time value for the second communication unit is greater than or equal to a fourth preset time, the power management unit turns on the power to the second communication unit.

The electronic device can be a terminal or other devices besides a terminal. For example, the electronic device can be a mobile phone, tablet computer, laptop computer, PDA, in-vehicle electronic device, mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. It can also be a server, edge computing gateway (ECG), network attached storage (NAS), personal computer (PC), television (TV), ATM, or self-service machine, etc. This application embodiment does not specifically limit the scope of the electronic device.
