Methods to reduce power consumption, terminal devices, network devices and storage media

Abstract

This application relates to a method for reducing power consumption, a terminal device, a network device, and a storage medium. When the terminal device confirms that the network device has packet filtering capabilities, it determines whether there is a user-perceptible service based on the communication method, mobility status, and service data. If an abnormal wake-up message is received from the network device and the terminal device has no user-perceptible service, the terminal device sends a first control command to the network device. The network device parses the first control command and obtains wake-up source information, then filters the packets sent from the network server to the terminal device based on this information. In this technical solution, the network device filters abnormal wake-up messages sent to the terminal device based on the first control command sent by the terminal device, and does not send abnormal wake-up messages to the terminal device, thereby preventing the terminal device from being woken up by abnormal wake-up messages, reducing power consumption, extending standby time, and improving user experience.

Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a method for reducing power consumption, a terminal device, a network device, and a storage medium. Background Technology

[0002] When a terminal device is in a system sleep state after the screen is turned off (e.g., screen off at night, screen off during user work), it will exit the system sleep state upon receiving a message, thus waking up the terminal device. Waking up consumes power. If the terminal device receives multiple messages in a short period, it will be woken up multiple times, resulting in excessive power consumption, reduced standby time, and negatively impacting the user experience. Summary of the Invention

The first control instruction is used to instruct the network device to filter packets sent from the network server to the terminal device, and the first control instruction carries wake-up source information of the abnormal wake-up message. In the above technical solution, when the terminal device determines that the network device has a packet filtering function, receives an abnormal wake-up message, and has no user-perceptible services, it sends a first control instruction to the network device to instruct the network device to filter the abnormal wake-up message sent to the terminal device and not send the abnormal wake-up message to the terminal device, thereby avoiding the terminal device being woken up by the abnormal wake-up message, reducing the terminal device's power consumption, extending the terminal device's standby time, and improving the user experience.

It should be understood that, unless otherwise stated, " / " in this application means "or". For example, A / B can mean A or B. "And / or" in this application is merely a description of 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, and B alone. "At least one" refers to one or more. "More than one" refers to two or more. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, and a, b, and c (seven cases).

[0039] When a terminal device's screen is off (e.g., at night or during user work), it enters a system sleep state. However, upon receiving a message from the router, the terminal device exits sleep mode and connects to the router via Wi-Fi, thus waking up. This wake-up process consumes power. If the terminal device receives multiple messages within a short period, it will be woken up multiple times, reducing its standby time and resulting in excessive power consumption, negatively impacting the user experience.

[0040] To address the issue of excessive power consumption caused by frequent wake-ups of terminal devices in screen-off scenarios (e.g., screen-off at night or when the user is working), embodiments of this application provide a method for reducing power consumption. (See reference...) Figure 1 The diagram shown illustrates an application scenario of a power reduction method provided in an embodiment of this application. The method is applied to terminal devices (such as…). Figure 1 The terminal device 100 shown) and network equipment (such as Figure 1 In the network device 200 shown, the terminal device 100 establishes a communication connection with the network device 200 (e.g., communicating via a Wi-Fi channel) and can communicate with the network connected to the network device 200. When the network device 200 receives a message from the network server sent to the terminal device 100, it forwards the message to the terminal device 100 to wake it up. When the terminal device 100 receives a message sent by the network device 200, if it determines that the message is an abnormal wake-up message and the terminal device 100 meets preset conditions, it sends a first control command to the network device 200. Based on the wake-up source information of the message carried by the first control command, the network device 200 filters the messages sent by the network server to the terminal device 100. In this way, the network device 200 can filter abnormal wake-up messages sent by the network server and not send the messages to the terminal device, thereby avoiding the terminal device 100 being repeatedly woken up by abnormal wake-up sources, thus reducing the power consumption of the terminal device 100, extending the standby time of the terminal device 100, and improving the user experience.

[0041] In one embodiment of this application, the terminal device 100 may be a mobile phone, tablet computer, desktop computer, laptop computer, handheld computer, notebook computer, ultra-mobile personal computer (UMPC), netbook, as well as cellular phone, personal digital assistant (PDA), augmented reality (AR) device, virtual reality (VR) device, artificial intelligence (AI) device, wearable device, in-vehicle device, smart home device, and / or smart city device, etc. In one embodiment of this application, the network device 200 may be a switch, router, or hub.

[0042] In one embodiment of this application, the terminal device 100 includes a network environment perception module 101, a mobility state perception module 102, a service scenario perception module 103, a service monitoring module 104, a first decision module 105, an anomaly monitoring module 106, a first hardware abstract layer (HAL) 107, a first Wi-Fi driver 108, and a first Wi-Fi chip 109.

[0043] The network environment sensing module 101 is used to determine the communication mode of the terminal device 100. The communication modes include Wi-Fi communication and data service communication, with data service communication including cellular data communication services. Wi-Fi communication refers to the communication mode where the terminal device 100 connects to the network device 200 via a Wi-Fi channel, and data service communication refers to the communication mode where the terminal device 100 connects to a base station (such as a cellular base station). In one embodiment of this application, if the network environment sensing module 101 receives a confirmation connection signal from a router (such as a Wi-Fi router), it determines that the communication mode of the terminal device 100 is Wi-Fi communication; if the network environment sensing module 101 receives a confirmation connection signal from a base station (such as a 4G or 5G base station), it determines that the communication mode of the terminal device 100 is data service. After determining the communication mode of the terminal device 100, the network environment sensing module 101 sends the communication mode information to the service monitoring module 104.

[0044] The motion state sensing module 102 is used to determine the motion state of the terminal device 100 and send the motion state to the service monitoring module 104. In one embodiment of this application, the motion state sensing module 102 can detect the motion state of the terminal device 100 through sensors of the terminal device 100, such as an accelerometer or a gravity sensor, and send the motion state to the service monitoring module 104. In one embodiment of this application, the motion state includes a moving state and a stationary state.

[0045] The business scenario perception module is used to acquire business data from the terminal device 100 and send the acquired business data to the business monitoring module 104. In one embodiment of this application, the business data may include, but is not limited to: audio data, ambient light intensity value change data, system background download data, screen-on events, and alarm clock ringing.

[0046] The service monitoring module 104 is used to determine whether the terminal device 100 has any user-perceptible service based on the communication method, movement result, and service data of the terminal device 100, and to send the result of whether there is a user-perceptible service or not to the first decision module 105. In one embodiment of this application, determining whether the terminal device 100 has no user-perceptible service based on the communication method, movement result, and service data of the terminal device 100 includes: if it is determined that the communication method of the terminal device 100 is Wi-Fi communication, if it is determined that the terminal device 100 meets one or more of the following conditions: the terminal device 100 is in a stationary state, the terminal device 100 does not output audio data, the change data of the ambient light intensity value detected by the terminal device 100 does not exceed the preset light intensity value, there is no data being downloaded in the system background, and the alarm rings when the timer reaches the set time, then it is determined that the terminal device 100 has no user-perceptible service. In one embodiment of this application, a terminal device 100 is determined to have user-perceptible services when one or more of the following conditions are met: the communication mode of the terminal device 100 is data service communication; the motion state of the terminal device 100 is a moving state; the terminal device 100 outputs audio data; the terminal device 100 detects a change in ambient light intensity value that exceeds a preset light intensity value; the terminal device 100 downloads data in its background system; the terminal device 100 experiences a screen-on event; or the alarm clock of the terminal device 100 rings.

[0047] The first Wi-Fi chip 109 receives a message sent by the network device 200 and sends the message to the first Wi-Fi driver 108. The first Wi-Fi driver 108 sends the message to the anomaly monitoring module 106 through the first hardware abstraction layer 107. The anomaly monitoring module 106 obtains the wake-up source information and the message reception time information from the message, and determines whether the message is an abnormal wake-up message based on the wake-up source information and the message reception time information. In one embodiment of this application, the wake-up source information includes the Internet Protocol Address (IP) address, port number, and protocol information of the message sender, and the IP address and port number of the message receiver. For example, refer to... Figure 2 The wake-up source information shows that the sender's IP address is 124.70.116.53, the sender's port number is 433, and the sender's protocol is Transmission Control Protocol (TCP). The receiver's IP address is 10.35.95.36, and the receiver's port number is 38086. In one embodiment of this application, determining whether a message is an abnormal wake-up message based on the wake-up source information and the message's reception time information includes: determining whether the number of times the message is received within a preset time period is greater than or equal to a preset number; if the number of times the message is received within the preset time period is greater than or equal to the preset number, the message is determined to be an abnormal wake-up message; if the number of times the message is received within the preset time period is less than the preset number, the message is determined to be a normal wake-up message. In one embodiment of this application, the preset time period and the preset number can be set as needed; for example, the preset time period can be set to 5 minutes, and the preset number can be set to 5 times.

[0048] refer to Figure 3 The image shown is a schematic diagram of a message provided in an embodiment of this application. Figure 3 Based on the message reception time, the anomaly monitoring module 106 can determine that within 5 minutes after 11:45:38 on July 20, 2023, a total of 11 messages were acquired, and all messages had the same wake-up source information. Since the number of times the same message was received within a preset time period (e.g., 5 minutes) is greater than a preset number (e.g., 5 times), the message is determined to be an abnormal wake-up message. After determining the abnormal wake-up message, the anomaly monitoring module 106 sends the abnormal wake-up message to the first decision module 105.

[0049] When the first decision module 105 determines that the network device 200 supports packet filtering, the terminal device 100 has an abnormal wake-up message, and the terminal device 100 has no user-perceptible services, it sends a first control command to the network device 200 to filter the packets sent from the network server to the terminal device 100. The first control command carries wake-up source information of the abnormal wake-up message. In one embodiment of this application, the decision module 105 sends an inquiry request to the network device 200 regarding whether it supports packet filtering, and upon receiving a response from the network device 200 indicating support for packet filtering, it can determine that the network device 200 supports packet filtering.

[0050] In one embodiment of this application, the network device 200 includes a second decision module 201, a network protocol stack 202, a second Wi-Fi driver 203, and a second Wi-Fi chip 204. The second decision module 201 is used to obtain a first control command sent by the terminal device 100 and send the first control command to the network protocol stack 202. The network protocol stack 202 parses the first control command to obtain the wake-up source information of the abnormal wake-up message and sends the first control command and the wake-up source information of the abnormal wake-up message to the second Wi-Fi driver 203. The second Wi-Fi driver 203 responds to the first control command and filters the messages received by the second Wi-Fi chip 204 from the network server according to the wake-up source information of the abnormal wake-up message.

[0051] In one embodiment of this application, filtering packets sent by the second Wi-Fi chip 204 from the network server according to wake-up source information includes: if the packet contains wake-up source information of an abnormal wake-up packet, the network device filters out the packet containing wake-up source information sent by the network server and does not send it to the terminal device. Thus, the network device 200 can filter abnormal wake-up packets sent by the network server according to the first control command sent by the terminal device, and not send the packets to the terminal device, thereby preventing the terminal device 100 from being woken up by an abnormal wake-up source, thereby reducing the power consumption of the terminal device 100 and improving the user experience.

Without departing from the scope of the claims, the execution order of multiple steps can be interchanged, and some steps can be omitted. Some embodiments will be described below with reference to the accompanying drawings. The power reduction method includes the following steps.

[0053] Step S401: The terminal device establishes a Wi-Fi connection with the network device.

[0054] To clearly illustrate the example, the following description uses a mobile phone as the terminal device and a router as the network device 200 to illustrate the specific implementation of the power consumption reduction method. In one embodiment of this application, the mobile phone responds to the user's selection of the Wi-Fi network option in the phone's network settings interface and establishes a Wi-Fi connection with the router. (See reference...) Figure 5 The diagram shown is a schematic representation of a network settings interface according to one embodiment of this application. The network settings interface includes a Wi-Fi network switch option and at least one Wi-Fi network connection option. Each Wi-Fi network connection option corresponds to a router. When the mobile phone detects that the user has enabled the Wi-Fi network switch option and selected a Wi-Fi network connection option on the network settings interface, it establishes a Wi-Fi connection between the mobile phone and the router corresponding to the selected Wi-Fi network connection option.

[0055] refer to Figure 6The diagram illustrates a communication connection between a mobile phone and a router according to an embodiment of this application. In one embodiment, the mobile phone and the router establish a Wi-Fi connection via Wi-Fi network protocols (such as 802.11a, 802.11b, and 802.11e). In another embodiment, the mobile phone can interact with the router sequentially through a sequence of Probe frames, Authentication frames, Association frames, and Dynamic Host Configuration Protocol (DHCP) frames to establish the Wi-Fi connection. Specifically, in the Probe frame interaction, the mobile phone sends a Probe Request to discover if there is a connectable router in the surrounding environment. If the mobile phone receives a Probe Response frame from the router, it confirms the presence of a connectable router. In the Authentication frame interaction, the mobile phone sends an Authentication Request frame to determine if the capabilities of the mobile phone and the router are compatible. If the mobile phone receives a Successful Authentication Response frame from the router, it confirms that the capabilities of the mobile phone and the router are compatible. In the Association frame interaction process, the mobile phone sends an Association Request frame to request an association with the router. If the mobile phone receives an Association Response frame from the router carrying a successful association reply, then the mobile phone is confirmed to be associated with the router. In the DHCP frame interaction process, the mobile phone can establish a communication connection with the router based on the IP address configured on the router. The methods by which a mobile phone establishes a Wi-Fi connection with a router via the Wi-Fi network protocol can refer to existing related technologies; the detailed interaction process of establishing a Wi-Fi connection between a mobile phone and a router will not be described here.

[0056] In one embodiment of this application, establishing a Wi-Fi connection between a mobile phone and a router via the Wi-Fi network protocol includes: the first Wi-Fi chip of the mobile phone can establish a connection with the second Wi-Fi chip of the router via the Wi-Fi network protocol.

[0057] In step S402, the terminal device sends a lookup request to the network device, wherein the lookup request is used to determine whether the network device has packet filtering functionality.

[0058] In one embodiment of this application, reference is made to Figure 6After establishing a connection with the router, the mobile phone sends a discover request frame to the router to determine whether the network device has packet filtering capabilities. Packet filtering refers to the router's ability to filter packets sent from the network server to the terminal device. If the router has the ability to filter packets sent from the network server to the terminal device, then the router is confirmed to have packet filtering functionality.

[0059] In step S403, after receiving the confirmation reply sent by the network device in response to the lookup request, the terminal device determines that the network device has the function of packet filtering.

[0060] In one embodiment of this application, after the terminal device receives the support (Ack) reply frame sent by the network device in response to the lookup request frame, it determines that the network device has the function of packet filtering, thus realizing the mobile phone's confirmation of the router's end-to-end management capability.

[0061] Step S404: The terminal device obtains the terminal device's communication mode, mobility status, and service data, and determines whether the terminal device has no user-aware service based on the terminal device's communication mode, mobility status, and service data. If it is determined that the mobile phone has no user-aware service, proceed to step S405; if it is determined that the mobile phone has a user-aware service, proceed to step S408.

[0062] In one embodiment of this application, the mobile phone's network environment sensing module determines that the mobile phone's communication mode is Wi-Fi communication based on the connection confirmation signal returned by the router, or determines that the mobile phone's communication mode is data service communication based on the connection confirmation signal returned by the base station. The mobile phone sends the determined communication mode information to the mobile phone's service monitoring module. The mobile phone's motion state sensing module detects the mobile phone's motion state through the mobile phone's accelerometer. For example, the motion state sensing module detects the mobile phone's acceleration or speed through the accelerometer. If the mobile phone's acceleration is greater than or equal to a preset acceleration value, or the mobile phone's speed is greater than or equal to a preset speed value, it determines that the mobile phone is in a moving state. If the mobile phone's acceleration is less than the preset acceleration value, or the mobile phone's speed is less than the preset speed value, it determines that the mobile phone is in a stationary state. The mobile phone's motion state sensing module sends the mobile phone's moving state or stationary state to the mobile phone's service monitoring module.

[0063] The mobile phone's business scenario perception module is used to acquire the mobile phone's business data and send it to the business monitoring module. In one embodiment of this application, in a scenario where the mobile phone outputs audio, the business scenario perception module uses the audio data output by the mobile phone as business data. In one embodiment of this application, when the mobile phone moves from a dark environment to a brightly lit environment, the business scenario perception module acquires the change data of the ambient light intensity value as business data. In one embodiment of this application, in a scenario where the mobile phone's background system is downloading data, the business scenario perception module acquires the downloaded data from the background system as business data. In one embodiment of this application, in a scenario where the mobile phone's screen is on, the business scenario perception module acquires the screen-on event of the mobile phone as business data. In one embodiment of this application, in a scenario where the mobile phone's alarm clock application is activated, the business scenario perception module acquires the ringing data of the alarm clock (i.e., the alarm clock application) as business data.

[0064] In one embodiment of this application, when the service monitoring module determines that the mobile phone meets a first preset condition, it determines that the mobile phone has no user-perceptible service. The first preset condition includes, but is not limited to: the mobile phone's communication mode is Wi-Fi communication, the mobile phone's motion state is stationary, the mobile phone is not outputting audio data, the change data of the ambient light intensity value detected by the mobile phone does not exceed a preset light intensity value, the mobile phone has not experienced a screen-on event, the mobile phone's system background has no download data, and the mobile phone's alarm clock has not rung, thus determining that the mobile phone has no user-perceptible service.

[0065] When the service monitoring module determines that the mobile phone meets the second preset condition, it determines that the mobile phone has a user-perceptible service. In this embodiment, the second preset condition can be any one or a combination of the following conditions: the mobile phone's communication mode is data service communication; the mobile phone's movement state is mobile; the mobile phone outputs audio data; the change in ambient light intensity detected by the mobile phone exceeds a preset light intensity value; the mobile phone experiences a screen-on event; the mobile phone's system background has download data; the mobile phone's alarm clock rings. In the above embodiment, by determining whether the mobile phone meets the first and second preset conditions, it can be determined whether the mobile phone has a user-perceptible service scenario.

[0066] Step S405: The terminal device receives the message sent by the network device and determines whether the message is an abnormal wake-up message.

[0067] In one embodiment of this application, the first Wi-Fi chip of the mobile phone receives a message forwarded by the router and sends the message to the first Wi-Fi driver of the mobile phone. The first Wi-Fi driver sends the message to the abnormal monitoring module of the mobile phone through the first hardware abstraction layer of the mobile phone. The abnormal monitoring module 106 obtains the wake-up source information and the reception time information of the message from the message, and determines whether the number of times the message is received within a preset time period is greater than or equal to a preset number based on the wake-up source information and the reception time information of the message. If the number of times the message is received within the preset time period is greater than or equal to the preset number, the message is determined to be an abnormal wake-up message; if the number of times the message is received within the preset time period is less than the preset number, the message is determined to be a normal wake-up message. Thus, this embodiment determines whether an abnormal wake-up message has been received based on the wake-up source information and the reception time information of the message, thereby realizing the monitoring of the wake-up source. In one embodiment of this application, the wake-up source information includes the IP address, port number, and protocol information of the message sender (such as a network server), and the IP address and port number of the message receiver (such as a mobile phone). In one embodiment of this application, if the message is an abnormal wake-up message, step S406 is executed; if the message is a normal wake-up message, the process returns to step S404.

[0068] In step S406, the terminal device sends a first control instruction to the network device, wherein the first control instruction carries the wake-up source information of the abnormal wake-up message.

[0069] In one embodiment of this application, when the first decision module of the mobile phone determines that the router has the function of supporting packet filtering, if it receives an abnormal wake-up message and there is no user-perceptible service, it sends a first control command to the router to filter the packets sent to the mobile phone by the network server. In another embodiment of this application, after the terminal device sends the first control command to the network device, if it receives an Ack reply frame from the network device in response to the first control command, it determines that the network device has received the first control command.

[0070] In step S407, the network device parses the wake-up source information of the abnormal wake-up message from the first control command, and filters the messages sent by the network server to the terminal device according to the wake-up source information of the abnormal wake-up message.

[0071] In one embodiment of this application, the router's second decision module obtains a first control command sent by the mobile phone and sends the first control command to the router's network protocol stack. The network protocol stack analyzes the wake-up source information of the abnormal wake-up message from the first control command and sends the first control command and the wake-up source information of the abnormal wake-up message to the router's second Wi-Fi driver. (See reference...) Figure 6The second Wi-Fi driver responds to the first control command and filters the packets from the network server received by the router's second Wi-Fi chip according to the wake-up source information of the abnormal wake-up message.

[0072] In one embodiment of this application, filtering messages sent from the network server to the terminal device based on the wake-up source information of the abnormal wake-up message includes: if the message from the network server includes the wake-up source information of the abnormal wake-up message, filtering the message from the network server and not sending the message from the network server to the mobile phone.

[0073] In one embodiment of this application, after receiving the first control command, the router's second Wi-Fi driver replies with a first confirmation message to the mobile phone to notify the mobile phone that it has received the first control command.

[0074] In step S408, when it is determined that the terminal device has user-aware services, the terminal device sends a second control command to the network device.

[0075] refer to Figure 6 In one embodiment of this application, the mobile phone again obtains the communication mode, mobility status and service data of the terminal device, and when it determines that the terminal device has user-perceptible services based on the obtained communication mode, mobility status and service data of the terminal device, it sends a second control command to the router to instruct the router not to filter the packets sent to the mobile phone by the network server.

[0076] In step S409, the network device does not filter the packets sent from the network server to the terminal device according to the second control instruction.

[0077] In one embodiment of this application, the router's second decision module obtains a second control command sent by the mobile phone and sends the second control command to the router's network protocol stack. The network protocol stack parses the second control command and sends the parsed second control command to the router's second Wi-Fi driver. The second Wi-Fi driver responds to the second control command without filtering the packets sent from the network server to the terminal device.

[0078] In one embodiment of this application, after receiving the second control command, the router's second Wi-Fi driver replies with a second confirmation message to the mobile phone to notify the mobile phone that it has received the second control command.

[0079] In one embodiment of this application, when the mobile phone's service determination module determines that the mobile phone's communication mode has changed from Wi-Fi communication to data service communication, such as cellular data service communication, it determines that the mobile phone has user-aware services and sends the user-aware services to the mobile phone's first decision module. The mobile phone's first decision module sends a second control instruction to the router to instruct the router not to filter the packets sent to the mobile phone by the network server. In this way, when the mobile phone is detected to be communicating with the base station, the router's function of filtering packets is canceled, and the mobile phone can receive packets from the network server.

[0080] In one embodiment of this application, when the mobile phone's motion state changes from a stationary state to a moving state, the mobile phone's service determination module determines that the mobile phone has user-perceptible services and sends the user-perceptible services to the mobile phone's first decision module. The mobile phone's first decision module sends a second control instruction to the router to instruct the router to cancel the filtering of packets sent from the network server to the mobile phone. Thus, in the scenario where mobile phone movement is detected, the router's function of filtering packets is canceled, enabling the mobile phone to receive packets from the network server.

[0081] In one embodiment of this application, when the mobile phone's service determination module determines that the mobile phone has a user-aware service when it determines that the mobile phone is outputting audio data, it sends the user-aware service to the mobile phone's first decision module. The mobile phone's first decision module sends a second control instruction to the router to instruct the router not to filter the packets sent to the mobile phone by the network server. In this way, when the mobile phone is detected to be outputting audio data, the router's function of filtering packets is canceled, and the mobile phone can receive packets from the network server.

[0082] In one embodiment of this application, when the mobile phone's service determination module determines that the change in the ambient light intensity value of the mobile phone exceeds a preset light intensity value, it determines that the mobile phone has a user-perceptible service and sends the user-perceptible service to the mobile phone's first decision module. The mobile phone's first decision module sends a second control instruction to the router to instruct the router not to filter the packets sent to the mobile phone by the network server. Thus, when a scenario is detected in which the change in the ambient light intensity value of the mobile phone exceeds the preset light intensity value (such as when the mobile phone moves from a dark lighting environment to a lit lighting environment), the router's function of filtering packets is canceled, enabling the mobile phone to receive packets from the network server.

[0083] In one embodiment of this application, when the mobile phone's service determination module determines that the mobile phone has a user-aware service when it determines that the mobile phone has a screen-on event, it sends the user-aware service to the mobile phone's first decision module. The mobile phone's first decision module sends a second control instruction to the router to instruct the router not to filter the packets sent to the mobile phone by the network server. Thus, in the scenario where the mobile phone's screen is detected to be on, the router's function of filtering packets is canceled, and the mobile phone can receive packets from the network server.

[0084] In one embodiment of this application, when the mobile phone's service determination module determines that there is download data in the background of the mobile phone's system, it determines that the mobile phone has user-aware services and sends the user-aware services to the mobile phone's first decision module. The mobile phone's first decision module sends a second control instruction to the router to instruct the router not to filter the packets sent to the mobile phone by the network server. In this way, when the background system is detected to be downloading data, the router's function of filtering packets is canceled, and the mobile phone can receive packets from the network server.

[0085] In one embodiment of this application, when the alarm clock rings, the mobile phone's service determination module determines that the mobile phone has a user-aware service and sends the user-aware service to the mobile phone's first decision module. The mobile phone's first decision module sends a second control instruction to the router to instruct the router not to filter the packets sent to the mobile phone by the network server. Thus, when the mobile phone is detected to be ringing an alarm clock, the router's packet filtering function is canceled, enabling the mobile phone to receive packets from the network server.

[0086] In the above embodiments, when the terminal device determines that the network device has the function of supporting packet filtering, the terminal device receives an abnormal wake-up message, and the terminal device has no user-perceptible service, it sends a first control instruction to the network device to instruct the network device to filter the abnormal wake-up message sent to the terminal device and not send the abnormal wake-up message to the terminal device, thereby avoiding the terminal device being woken up, thereby reducing the power consumption of the terminal device and improving the user experience.

[0092] The processor 110 may also include a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. This memory can store instructions or data that the processor 110 has just used or that are used repeatedly. If the processor 110 needs to use the instruction or data again, it can retrieve it directly from the memory. This avoids repeated accesses, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

For example, the processor 110 communicates with the Bluetooth module in the wireless communication module 160 via the UART interface to implement Bluetooth functionality. In some embodiments, the audio module 170 can transmit audio signals to the wireless communication module 160 via the UART interface to enable music playback through Bluetooth headphones.

[0098] The MIPI interface can be used to connect the processor 110 to peripheral devices such as the display screen 194 and the camera 193. The MIPI interface includes a camera serial interface (CSI) and a display serial interface (DSI). In some embodiments, the processor 110 and the camera 193 communicate via the CSI interface to enable the shooting function of the terminal device 100. The processor 110 and the display screen 194 communicate via the DSI interface to enable the display function of the terminal device 100.

[0099] The GPIO interface can be configured via software. It can be configured as a control signal or a data signal. In some embodiments, the GPIO interface can be used to connect the processor 110 to a camera 193, a display screen 194, a wireless communication module 160, an audio module 170, a sensor module 180, etc. The GPIO interface can also be configured as an I2C interface, an I2S interface, a UART interface, a MIPI interface, etc.

It can also be used to connect headphones for audio playback. This interface can also be used to connect other terminal devices 100, such as AR devices.

[0101] It is understood that the interface connection relationships between the modules illustrated in the embodiments of this application are merely illustrative and do not constitute a structural limitation on the terminal device 100. In other embodiments of this application, the terminal device 100 may also adopt different interface connection methods or a combination of multiple interface connection methods as described in the above embodiments.

[0102] The charging management module 140 receives charging input from a charger. The charger can be a wireless charger or a wired charger.

In some other embodiments, the power management module 141 may also be located within the processor 110. In other embodiments, the power management module 141 and the charging management module 140 may be located in the same device.

[0104] The wireless communication function of the terminal device 100 can be implemented through antenna 1, antenna 2, mobile communication module 150, wireless communication module 160, modem processor and baseband processor, etc.

[0105] Antennas 1 and 2 are used to transmit and receive electromagnetic wave signals. Each antenna in terminal device 100 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.

In some embodiments, at least some functional modules of the mobile communication module 150 may be housed in the processor 110. In some embodiments, at least some functional modules of the mobile communication module 150 and at least some modules of the processor 110 may be housed in the same device.

[0107] The modem processor may include a modulator and a demodulator. The modulator modulates the low-frequency baseband signal to be transmitted into a mid-to-high frequency signal. The demodulator demodulates the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After processing by the baseband processor, the low-frequency baseband signal is transmitted to the application processor. The application processor outputs sound signals through an audio device (not limited to speaker 170A, receiver 170B, etc.) or displays images or videos through the display screen 194. In some embodiments, the modem processor may be a separate device. In other embodiments, the modem processor may be independent of the processor 110 and may be housed in the same device as the mobile communication module 150 or other functional modules.

[0108] The wireless communication module 160 can provide solutions for wireless communication applications on the terminal device 100, including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), and infrared (IR) technologies.

[0110] Terminal device 100 implements display functions through a GPU, display screen 194, and application processor. The GPU is a microprocessor for image processing, connected to the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations and for graphics rendering. Processor 110 may include one or more GPUs, which execute program instructions to generate or modify display information.

[0111] The display screen 194 is used to display images, videos, etc. The display screen 194 includes a display panel. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a Miniled LED, a MicroLED, a Micro-OLED, a quantum dot light-emitting diode (QLED), etc. In some embodiments, the terminal device 100 may include one or N display screens 194, where N is a positive integer greater than 1.

[0112] Terminal device 100 can perform shooting functions through ISP, camera 193, video codec, GPU, display 194 and application processor.

[0113] The ISP (Image Signal Processor) is used to process data fed back from the camera 193. For example, when taking a picture, the shutter is opened, and light is transmitted through the lens to the camera's photosensitive element. The light signal is converted into an electrical signal, and the camera's photosensitive element transmits the electrical signal to the ISP for processing, transforming it into an image visible to the naked eye. The ISP can also perform algorithmic optimization of image noise, brightness, and skin tone. The ISP can also optimize parameters such as exposure and color temperature of the shooting scene.
