Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to an Internet connection method, a terminal device, a network device, and a storage medium. Background Art

[0002] When a terminal device is connected to a Wi-Fi network, the network speed of the terminal device is related to the channel air interface quality of the current channel of the terminal device. On the channel of the terminal device, the more routers are connected to the channel for communication, or the larger the data traffic of the router, the higher the channel load is, and the lower the network speed of the terminal device is, causing the terminal device to be stuck when accessing the Internet. In the related art, the solution to the problem of stuck access to the Internet by the terminal device is to connect the terminal device to other routers or to connect the terminal device to a cellular base station. However, if the terminal device cannot use other routers for network connection, for example, a private router requires password verification before allowing the terminal device to connect, and by connecting the terminal device to a cellular base station, the terminal device's own traffic will be consumed in addition, so the stability of the terminal device's network connection cannot be ensured, and the user's Internet experience is affected. Summary of the invention

[0003] In view of the above, it is necessary to provide an Internet connection method, a terminal device, a network device and a storage medium to solve the problem of Internet access lag.

[0004] In a first aspect, an embodiment of the present application provides an Internet connection method, which is applied to a communication system, wherein the communication system includes a terminal device and a network device, and the method includes: when the terminal device determines that the network device has a channel switching function, the terminal device obtains the channel load of the working channel of the terminal device; if it is determined that an Internet freeze event caused by an air interface occurs according to the channel load of the working channel, the terminal device determines whether an interference value of a channel is detected to be less than a preset interference value; if it is detected that the interference value of at least one channel is less than the preset interference value, the terminal device obtains a screen state and a motion state; if it is determined that the terminal device has no user-perceivable service according to the screen state and the motion state, the terminal device determines a switching channel from at least one detected channel, and sends a switching instruction carrying the switching channel to the network device; the network device responds to the switching instruction, parses the switching instruction to determine the switching channel, sets the switching channel to an updated working channel and restarts the network device; in response to a notification of successful channel setting sent from the network device, the terminal device re-establishes a communication connection with the network device. In the above technical solution, when the terminal device determines that an Internet access freeze event has occurred due to air interface reasons, it scans the interference values ​​of other channels and selects the channel with the smallest interference value as the switching channel. When it is determined that the terminal device has no user-perceivable service, it sends a channel switching instruction to the network device. The network device parses the switching channel from the switching instruction, sets the working channel of the network device to the switching channel, restarts the network device, and makes the network device work on the new working channel. After the terminal device reconnects to the network device, it communicates with the network device through the new working channel, thereby solving the problem of Internet freeze in the terminal device and improving the user's Internet experience. In addition, the above technical solution confirms the user-perceivable service, so as to avoid the problem of the user perceiving the network disconnection when the network device is restarting and setting the channel due to the presence of user-perceivable service at the terminal device.

In the above technical solution, when it is determined that the number of devices connected to the network device is one, it can be determined that the network device is only connected to the terminal device, so that when the network device responds to the switching instruction and restarts, even if the network device and the terminal device are temporarily disconnected, it will not affect the normal Internet access of other devices connected to the network device.

[0009] In one embodiment of the present application, the method further includes: if the network device is connected to multiple devices, the network device does not respond to the switching instruction. In the above technical solution, when it is determined that the number of devices connected to the network device is one, it can be determined that the network device is connected to multiple devices including the terminal device, so that the network device does not respond to the switching instruction, thereby avoiding affecting the normal Internet access of other devices connected to the network device when the network device responds to the switching instruction to restart.

In the above technical solution, when the terminal device determines that an Internet access freeze event has occurred due to air interface reasons, it scans the interference values ​​of other channels and selects the channel with the smallest interference value as the switching channel. When it is determined that the terminal device has no user-perceivable service, it sends a channel switching instruction to the network device to instruct the network device to set the working channel as the switching channel. After the terminal device reconnects to the network device, it communicates with the network device through the new working channel, thereby solving the problem of Internet freeze in the terminal device and improving the user's Internet experience. In addition, the above technical solution confirms the user-perceivable service, so as to avoid the problem of the user being able to perceive the network disconnection and affecting the Internet experience when the network device is restarting and setting the channel due to the presence of user-perceivable services at the terminal device.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by technicians in the technical field in this application. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. It should be understood that, unless otherwise specified in this application, " / " means or. For example, A / B can represent A or B.

[0036] When a terminal device is connected to a Wi-Fi network, the network speed of the terminal device is related to the air interface quality of the current channel of the terminal device. On the channel of the terminal device, the more routers are connected to the channel, or the larger the data traffic of the router, the higher the channel load, the lower the network speed of the terminal device, and the terminal device may experience lag in surfing the Internet. Figure 1 As shown in FIG. 1 , starting from 2.4 GHz, channels 1, 2, and 3 are formed every 5 MHz, and so on until channel 14. Figure 1 As shown, on channel 1, the number of routers connected to the channel for communication is 5, and on channel 12, the number of routers connected to the channel for communication is 2. Since the number of routers connected to channel 1 is greater than the number of routers connected to channel 12, the load of channel 1 is higher than the load of channel 12. Assuming that the routers working on channel 1 include router A, and the routers working on channel 12 include router B, based on the above situation, the network speed of the terminal device when communicating with router A is lower than the network speed when communicating with router B, and even the problem of Internet access freeze occurs. In the related art, the solution to the problem of terminal device Internet access freeze is to connect the terminal device to other routers or to connect the terminal device to a cellular base station. However, if the terminal device cannot use other routers to access the Internet, for example, a private router requires password verification before allowing the terminal device to connect, and by connecting the terminal device to a cellular base station, the terminal device's own traffic will be consumed additionally, thus increasing the user's expenses and affecting the user's Internet experience.

[0037] In order to solve the problem of Internet access lag when a terminal device is connected to a wireless network (eg, Wi-Fi), an embodiment of the present application provides an Internet access connection method. Figure 2 As shown, it is an application scenario diagram of the method for reducing power consumption provided by an embodiment of the present application. The method is applied to a terminal device (such as Figure 2 The terminal device 100 shown in FIG. Figure 2 The terminal device 100 establishes a communication connection with the network device 200 (for example, communicating through a Wi-Fi channel), and can communicate with the network connected to the network device 200 through the network device 200, thereby realizing the Internet access function. When the terminal device 100 determines that the air interface quality of the working channel for communication connection with the network device 200 is poor (for example, the number of connections of the router connected to the working channel exceeds the preset number, or the data traffic of the router exceeds the preset data traffic), the terminal device 100 scans the interference value of other channels, and selects the channel corresponding to the minimum interference value as the switching channel, and sends a channel switching instruction to the network device 200 when it is determined that the terminal device meets the preset working conditions. The network device 200 sets the working channel of the network device 200 to the switching channel and restarts according to the information of the switching channel carried by the channel switching instruction. After the network device 200 is restarted, the terminal device 100 reconnects to the network device 200 and communicates with the network device 200 through the new working channel (i.e., the switching channel), thereby solving the problem of freezing when the terminal device 100 is online and improving the user's online experience.

[0038] In one embodiment of the present application, the terminal device 100 may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) device, a virtual reality (VR) device, an artificial intelligence (AI) device, a wearable device, an in-vehicle device, a smart home device, and / or a smart city device. In one embodiment of the present application, the network device 200 may be a switch, a router, or a hub.

[0039] In one embodiment of the present application, the terminal device 100 includes a screen-on perception module 101, a mobile state perception module 102, a business scenario perception module 103, a first decision module 104, a user experience quality evaluation module 105, a first Wi-Fi driver 106, a first Wi-Fi chip 107, and a kernel protocol stack 108.

[0040] The screen-on perception module 101 is used to obtain the screen status of the terminal device 100 and send the screen status to the business scenario perception module 103. In one embodiment of the present application, the screen status of the terminal device 100 includes a screen-on status and a screen-off status. The screen-on perception module 101 obtains whether the screen is on by calling the isScreenOn() function of the power management (Power Manager) system. After calling the isScreenOn() function, if the Boolean value returned by the isScreenOn() function is a true value, it is determined that the screen status of the terminal device 100 is a screen-on status. If the Boolean value returned by the isScreenOn() function is a false value, it is determined that the screen status of the terminal device 100 is an off-screen status.

[0041] The mobile state sensing module 102 is used to determine the motion state of the terminal device 100, and send the motion state to the business scene sensing module 103. In one embodiment of the present application, the mobile state sensing module 102 can detect the motion state of the terminal device 100 through a sensor of the terminal device 100, such as an acceleration sensor or a gravity sensor, and send the motion state to the business scene sensing module 103. In one embodiment of the present application, the motion state includes a moving state and a stationary state.

[0042] The service scenario perception module 103 is used to obtain the screen status of the terminal device 100 from the screen perception module 101, and obtain the motion status of the terminal device 100 from the mobile status perception module 102, and determine whether the terminal device 100 has no user-perceivable service based on the screen status and motion status of the terminal device 100. If it is determined that the terminal device 100 has no user-perceivable service, the terminal device 100 issues a channel switching instruction to instruct the network device 200 to reset the channel according to the channel switching instruction. In the process of restarting and setting the channel, the network device 200 is temporarily disconnected from the network device 200. Since the terminal device is in a state of no user-perceivable service, the user of the terminal device 100 is not aware of it, which does not affect the Internet experience of the user of the terminal device 100.

[0043] In one embodiment of the present application, the business scenario perception module 103 determines that the terminal device 100 has no user-perceivable business when it determines that the screen state of the terminal device 100 is the screen-off state. For example, in a scenario where the terminal device 100 is off at night, the business scenario perception module 103 determines that the terminal device 100 has no user-perceivable business when it determines that the screen state of the terminal device 100 is the screen-off state. In another embodiment of the present application, the business scenario perception module 103 determines that the terminal device 100 has no user-perceivable business when it determines that the screen state of the terminal device 100 is the screen-off state and the motion state is the stationary state. For example, in the scenario of making a phone call, the terminal device 100 is in the screen-off state, but the terminal device has user-perceivable services (such as the data communication service of the current call). Therefore, it is not possible to accurately determine whether the terminal device has no user-perceivable services based only on whether the terminal device 100 is in the screen-off state. The motion state of the terminal device 100 must also be evaluated. When it is determined that the screen state of the terminal device 100 is the screen-off state and the motion state of the terminal device 100 is the stationary state, it is determined that the terminal device 100 has no user-perceivable services. For example, in the scenario of making a phone call, the screen state of the terminal device 100 is in the screen-off state, and the motion state of the terminal device 100 is in the moving state. At this time, it is determined that the terminal device 100 has service-perceivable services.

[0044] The user experience quality evaluation module 105 is used to send a first acquisition request to the first Wi-Fi chip 107 to obtain the channel load (channel load) of the working channel of the terminal device 100. Specifically, the user experience quality evaluation module 105 sends the first acquisition request to the first Wi-Fi chip 107 through the first Wi-Fi driver 106. The first Wi-Fi chip 107 obtains the channel load of the terminal device 100 according to the first acquisition request, and sends the channel load to the first Wi-Fi driver 106. The first Wi-Fi driver 106 sends the channel load to the user experience quality evaluation module 105. The user experience quality evaluation module 105 determines the air interface quality of the working channel of the terminal device 100 according to the channel load, and determines whether an Internet access freeze event caused by the air interface occurs according to the air interface quality of the working channel. In one embodiment of the present application, the working channel refers to the channel used when the terminal device 100 is connected to the network device 200 for communication. In one embodiment of the present application, if the channel load of the working channel is greater than or equal to the preset channel load threshold, that is, the channel load of the working channel is high, the user experience quality evaluation module 105 determines that the air interface quality of the working channel is poor, and determines that an Internet access freeze event caused by air interface reasons has occurred, and sends the Internet access freeze event caused by air interface reasons to the first decision module 104; if the channel load of the working channel is less than the preset channel load threshold, that is, the channel load is low, the user experience quality evaluation module 105 determines that the air interface quality of the working channel of the terminal device 100 is good, and determines that no Internet access freeze event caused by air interface reasons has occurred. In one embodiment of the present application, the preset channel load threshold can be set according to the number of network devices connected to the working channel, or the data traffic of the network device 200.

[0045] In another embodiment of the present application, the kernel protocol stack 108 is used to determine whether a message retransmission event occurs in the terminal device 100. In one embodiment of the present application, after the terminal device 100 sends a packet to the network device 200, if it is determined that the ACK response sent by the network device 200 in response to the packet is not received, the kernel protocol stack 108 determines that a message retransmission event occurs in the terminal device 100, and sends the message retransmission event to the user experience quality evaluation module 105. The user experience quality evaluation module 105 determines that the terminal device 100 has an Internet jam event based on the message retransmission event. However, the Internet jam event is not caused by poor air interface quality.

[0046] In one embodiment of the present application, the user experience quality evaluation module 105 is further configured to obtain interference values ​​of multiple channels other than the working channel. Specifically, the user experience quality evaluation module 105 sends a second acquisition request to the first Wi-Fi chip 107 to obtain beacon frames of multiple channels other than the working channel. For example, referring to Figure 1, the working channel is channel 1, then the user experience quality evaluation module 105 sends a second acquisition request to the first Wi-Fi chip 107 to obtain beacon frames of channel 2, channel 3, channel 4, etc. other than channel 1. Specifically, the user experience quality evaluation module 105 sends a second acquisition request to the first Wi-Fi chip 107 through the first Wi-Fi driver 106. The first Wi-Fi chip 107 obtains beacon frames of multiple channels other than the working channel according to the second acquisition request. The beacon frame of each channel carries the identity information of at least one device (such as a mobile phone, a laptop, etc.) connected to the channel. The first Wi-Fi chip 107 sends all the acquired beacon frames to the first Wi-Fi driver 106. The first Wi-Fi driver 106 sends all beacon frames to the user experience quality evaluation module 105. The user experience quality evaluation module 105 parses each beacon frame to obtain the identity information of the device included in each beacon frame, and determines the number of devices connected to the channel corresponding to the beacon frame according to the identity information of the device included in each beacon frame, determines the interference value of the channel according to the number of devices connected to the channel, and sends the interference value of the channel to the first decision module 104. In an embodiment of the present application, if the number of devices connected to the channel is more, the interference value of the channel is also greater; if the number of devices connected to the channel is less, the interference value of the channel is also smaller.

[0047] When the first decision module 104 determines that the network device 200 has a channel switching function, the terminal device 100 has an Internet access freeze event caused by an air interface reason, and the interference value of other channels except the working channel is small, if the service scenario perception module 10 receives no user-perceivable service, at least one channel is selected from channels other than the working channel according to the interference value of the channel as a switching channel, and a switching instruction carrying the switching channel is sent to the network device 200. In one embodiment of the present application, the first decision module 105 sends a query request to the network device 200 whether it has a channel switching function, and when receiving a reply with a channel switching function sent by the network device 200, it can be determined that the network device 200 has a channel switching function. For example, the first decision module 105 sends a query request to the first Wi-Fi driver 106 whether it has a channel switching function, and the first Wi-Fi driver 106 sends the query request to the first Wi-Fi chip 107. The first Wi-Fi chip 107 sends a query request to the network device 200, and receives a reply with a channel switching function sent by the network device 200 in response to the query request. The first Wi-Fi chip 107 sends the reply with the channel switching function to the first decision module 105 through the first Wi-Fi driver 106. The first decision module 105 determines that the network device 200 has the channel switching function according to the reply with the channel switching function sent by the network device 200.

[0048] In an embodiment of the present application, the network device 200 includes a monitoring module 201 , a second decision module 202 , a second Wi-Fi driver 203 , and a second Wi-Fi chip 204 .

[0049] The monitoring module 201 obtains the switching instruction sent by the terminal device 100, determines the number of devices connected to the network device 200, and sends the switching instruction and the number of devices connected to the network device 200 to the second decision module 202. In one embodiment of the present application, the monitoring module 201 determines the number of devices connected to the network device 200 by obtaining the number of identification tags of the devices connected to the network device 200 for communication. For example, if the identification tags of the devices connected to the network device 200 for communication include the identification tags of the terminal device 100 and the identification tags of the laptop computer, for a total of 2 identification tags, the monitoring module 201 determines that the number of devices connected to the network device 200 is 2.

[0050] The second decision module 202 receives the switching instruction sent by the monitoring module 201 and the number of devices connected to the network device 200. If it is determined that the number of devices connected to the network device 200 is greater than 1, the second decision module 202 does not respond to the switching instruction. If it is determined that the number of devices connected to the network device 200 is 1, that is, it is determined that the network device 200 is only connected to the terminal device 100, the second decision module 202 obtains the channel load of the working channel from the second Wi-Fi chip 204 to verify the channel load of the working channel between the terminal device 100 and the network device 200. Specifically, the second decision module 202 sends the third acquisition request to the second Wi-Fi chip 204 through the second Wi-Fi driver 203. The second Wi-Fi chip 204 obtains the channel load of the working channel of the network device 200 according to the third acquisition request, and sends the channel load of the working channel of the network device 200 to the second Wi-Fi driver 203. The second Wi-Fi driver 203 sends the channel load to the second decision module 202. If it is determined that the channel load of the working channel is greater than or equal to the preset channel load threshold (i.e., it is determined that the channel load of the working channel is high), and the number of devices connected to the network device 200 is 1, the second decision module 202 parses the switching channel from the switching instruction, sets the working channel of the network device 200 to the switching channel, restarts the network device 200, and makes the network device 200 work on the new working channel. After reconnecting to the network device 200, the terminal device 100 communicates with the network device 200 through the new working channel, thereby solving the problem of freezing when the terminal device 100 accesses the Internet and improving the user's Internet experience.

[0051] refer to Figure 3As shown, it is a flow chart of an Internet connection method provided by an embodiment of the present application. The method disclosed in the embodiment of the present application or the method shown in the flow chart includes one or more steps for implementing the method. Without departing from the scope of the claims, the execution order of multiple steps can be interchanged with each other, and some steps can also be omitted. Some embodiments will be described below in conjunction with the accompanying drawings. The Internet connection method includes the following steps.

[0052] Step S301: The terminal device establishes a communication connection with the network device.

[0053] For the sake of clarity, the following describes the specific implementation of the Internet connection method by taking the terminal device as a mobile phone, the network device 200 as a router, and the communication connection as a Wi-Fi connection as an example. In one embodiment of the present application, the mobile phone responds to the user selecting the Wi-Fi network option in the network setting interface of the mobile phone and establishes a Wi-Fi connection with the router. Figure 4 , which is a schematic diagram of a network setting interface provided by an embodiment of the present application. The network setting 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. After the mobile phone detects that the user turns on the Wi-Fi network switch option on the network setting interface and selects a Wi-Fi network connection option, a Wi-Fi connection is established between the mobile phone and the router corresponding to the selected Wi-Fi network connection option.

[0054] refer to Figure 5As shown, it is a schematic diagram of the communication connection between a mobile phone and a router provided in an embodiment of the present application. In an embodiment of the present application, the mobile phone and the router establish a Wi-Fi connection through a Wi-Fi network protocol (such as 802.11a, 802.11b, and 802.11e protocols). In an embodiment of the present application, the mobile phone can interact with the router in accordance with the interactive process of the probe frame, the authentication frame, the association frame, and the dynamic host configuration protocol (Dynamic Host Configuration Protocol, DHCP) frame to realize the Wi-Fi connection between the mobile phone and the router. Among them, in the interactive process of the Probe frame, the mobile phone sends a probe request (Probe Request) to find out whether there is a connectable router in the surrounding environment. If the mobile phone receives a probe response (ProbeResponse) frame sent by the router, it is determined that there is a connectable router in the surrounding environment. In the interactive process of the Authentication frame, the mobile phone sends an authentication request (Authentication Request) frame to determine whether the capabilities of the mobile phone and the router match. If the mobile phone receives an authentication response (AuthenticationResponse) frame carrying success (Successful) sent by the router, it is determined that the capabilities of the mobile phone and the router match. In the interaction process of the Association frame, the mobile phone sends an Association Request frame to request to establish an association with the router. If the mobile phone receives an Association Response frame sent by the router with a successful association, it is determined that the mobile phone is associated with the router. In the interaction process of the DHCP frame, the mobile phone can establish a communication connection with the router according to the IP address configured by the router. The means for the mobile phone to establish a Wi-Fi connection with the router through the Wi-Fi network protocol can refer to the existing related technologies. The detailed interaction process for establishing a Wi-Fi connection between the mobile phone and the router will not be described here.

[0055] In one embodiment of the present application, the mobile phone and the router establish a Wi-Fi connection through the Wi-Fi network protocol, including: a first Wi-Fi chip of the mobile phone can establish a connection with a second Wi-Fi chip of the router through the Wi-Fi network protocol.

[0056] Step S302: The terminal device sends a search request to the network device, wherein the search request is used to determine whether the network device has a channel switching function.

[0057] In one embodiment of the present application, reference Figure 5After the mobile phone establishes a connection with the router, it sends a discovery request frame to the router to determine whether the network device has a channel switching function. The channel switching function refers to the ability of the router to set and update the working channel.

[0058] Step S303: After receiving the confirmation response sent by the network device in response to the search request, the terminal device determines that the network device has a channel switching function.

[0059] In one embodiment of the present application, after the mobile phone receives the support (Ack) response reply frame sent by the network device in response to the search request, it is determined that the router has a channel switching function, thereby realizing the confirmation of the mobile phone on the channel switching function of the router.

[0060] In step S304, the terminal device obtains the channel load of the working channel and determines whether the channel load of the working channel is less than a preset channel load threshold. If the channel load of the working channel is greater than or equal to the preset channel load threshold, step S305 is executed. If the channel load of the working channel is less than the preset channel load threshold, step S304 is returned to continue monitoring the channel load of the working channel.

[0061] In one embodiment of the present application, the user experience quality evaluation module of the mobile phone sends a first acquisition request to the first Wi-Fi chip of the mobile phone through the first Wi-Fi driver of the mobile phone. The first Wi-Fi chip obtains the channel load of the working channel of the mobile phone according to the first acquisition request, and sends the channel load of the working channel to the first Wi-Fi driver. The first Wi-Fi driver sends the channel load of the working channel to the user experience quality evaluation module of the mobile phone. The user experience quality evaluation module compares the channel load of the working channel with the preset channel load threshold to determine the comparison result of the channel load of the working channel with the preset channel load threshold. In one embodiment of the present application, the preset channel load threshold can be set according to the number of routers connected to the working channel, or the data traffic of the router. The user experience quality evaluation module compares the number of routers of the working channel with the number of routers corresponding to the preset channel load threshold, so as to determine the comparison result of the channel load of the working channel with the preset channel load threshold.

[0062] Step S305: The terminal device determines that an Internet access freeze event occurs due to air interface reasons.

[0063] In one embodiment of the present application, if it is determined that the channel load of the working channel is greater than or equal to a preset channel load threshold, it is determined that the air interface quality of the working channel of the mobile phone does not meet the preset conditions. For the air interface quality that does not meet the preset conditions, it can be determined that the air interface quality is poor, and it is determined that an Internet access freeze event caused by air interface reasons has occurred, and the Internet access freeze event caused by air interface reasons is sent to the first decision module of the mobile phone; if it is determined that the channel load of the working channel is less than the preset channel load threshold, it is determined that the air interface quality of the working channel of the mobile phone meets the preset conditions (that is, indicating that the air interface quality of the working channel is good), and it is determined that an Internet access freeze event caused by air interface reasons has not occurred.

[0064] Step S306, the terminal device determines whether a channel with an interference value less than a preset interference value is detected. If the terminal device detects a channel with an interference value less than the preset interference value, step S307 is executed, otherwise, the terminal device does not detect a channel with an interference value less than the preset interference value, and returns to step S306.

[0065] In one embodiment of the present application, the user experience quality evaluation module of the mobile phone obtains the interference values ​​of multiple channels outside the working channel, and determines the channel whose interference value is less than the preset interference value according to the interference values ​​of the multiple channels. Specifically, the user experience quality evaluation module of the mobile phone sends a second acquisition request to the first Wi-Fi chip of the mobile phone through the first Wi-Fi driver of the mobile phone. The first Wi-Fi chip obtains the beacon frames of multiple channels outside the working channel according to the second acquisition request. The beacon frame of each channel carries the identity information of at least one device. The first Wi-Fi chip sends all the acquired beacon frames to the first Wi-Fi driver. The first Wi-Fi driver sends all beacon frames to the user experience quality evaluation module of the mobile phone. The user experience quality evaluation module parses each beacon frame to obtain the identity information of the device included in each beacon frame, and determines the number of devices connected to the channel corresponding to the beacon frame according to the identity information of the device included in each beacon frame, and uses the number of devices connected to the channel as the interference value of the channel, and sends the interference value of the channel to the first decision module of the mobile phone. The device connected to the channel can be a laptop, a tablet computer or a mobile phone of another user. The first decision module compares the interference value of the channel with the preset interference value, and when the interference value of the channel is less than the preset interference value, determines that a channel with an interference value less than the preset interference value is detected. In one embodiment of the present application, if the number of devices connected to the channel is greater, the interference value of the channel is greater; if the number of devices connected to the channel is less, the interference value of the channel is smaller.

[0066] Step S307, the terminal device obtains the screen state and motion state of the terminal device, and determines whether the terminal device has no user-perceivable service according to the screen state and motion state of the terminal device. If it is determined that the terminal device has no user-perceivable service, step S308 is executed; if it is determined that the mobile phone has a user-perceivable service, step S307 is returned to be executed.

[0067] In one embodiment of the present application, the screen-on sensing module of the mobile phone obtains the screen status of the mobile phone and sends the screen status to the business scenario sensing module of the mobile phone, wherein the screen status of the mobile phone includes the screen-on status and the screen-off status. For example, the screen-on sensing module of the mobile phone calls the function of the isScreenOn() function of the power management system. If the Boolean value returned by the isScreenOn() function is true, it is determined that the screen status of the mobile phone is the screen-on status. If the Boolean value returned by the isScreenOn() function is false, it is determined that the screen status of the mobile phone is the screen-off status.

[0068] The mobile state sensing module of the mobile phone determines the motion state of the mobile phone and sends the motion state to the business scenario sensing module, where the motion state includes the moving state and the stationary state. For example, the mobile state sensing module of the mobile phone detects the moving acceleration or moving speed of the mobile phone through the acceleration sensor. If the moving acceleration of the mobile phone is greater than or equal to the preset acceleration value, or the moving speed of the mobile phone is greater than or equal to the preset speed value, it is determined that the mobile phone is in a moving state. If the moving acceleration of the mobile phone is less than the preset acceleration value, or the moving speed of the mobile phone is less than the preset speed value, it is determined that the mobile phone is in a stationary state.

[0069] The business scenario perception module of the mobile phone obtains the screen state of the mobile phone from the screen-on perception module, obtains the motion state of the mobile phone from the mobile state perception module, and determines whether the mobile phone has no user-perceivable service based on the screen state and motion state of the mobile phone. In one embodiment of the present application, the business scenario perception module determines that the mobile phone has no user-perceivable service when it determines that the screen state of the mobile phone is an off-screen state and the motion state is a stationary state. In one embodiment of the present application, the business scenario perception module determines that the mobile phone has no user-perceivable service when it determines that the screen state of the mobile phone is an off-screen state.

[0070] Step S308: The terminal device selects at least one channel as a switching channel from all channels whose interference values ​​are less than a preset interference value, and sends a switching instruction carrying the switching channel to the network device.

[0071] In one embodiment of the present application, the first decision module of the mobile phone selects the channel corresponding to the minimum interference value from all channels whose interference values ​​are less than the preset interference value as the switching channel, and sends a switching instruction carrying the switching channel to the network device. The switching instruction is used to instruct the network device to set the working channel according to the switching channel carried in the switching instruction. In this embodiment, the first decision module of the mobile phone selects the channel corresponding to the minimum interference value from all channels whose interference values ​​are less than the preset interference value as the switching channel, and instructs the network device to set the working channel according to the switching channel, which can reduce the channel load of the working channel between the mobile phone and the router, increase the data transmission rate between the mobile phone and the router, and thus improve the Internet experience of the mobile phone.

[0072] refer to Figure 5 As shown, in one embodiment of the present application, after the terminal device sends a switching instruction to the network device, if an Ack response reply frame in response to the switching instruction from the network device is received, it is determined that the network device has received the switching instruction.

[0073] Step S309: The network device parses the switching channel from the switching instruction sent by the terminal device, sets the working channel of the network device as the switching channel, and restarts the network device.

[0074] In one embodiment of the present application, the monitoring module of the router receives a switching instruction sent by a mobile phone. For example, the monitoring module of the router receives the switching instruction sent by the mobile phone through the second Wi-Fi chip of the router. The monitoring module is also used to determine the number of devices connected to the router, and send the switching instruction and the number of devices connected to the router to the second decision module of the router. If it is determined that the number of devices connected to the router is greater than 1, the second decision module does not respond to the switching instruction. If it is determined that the number of devices connected to the router is 1, that is, it is determined that the router is only connected to the mobile phone, the second decision module sends a third acquisition request to the second Wi-Fi chip of the router through the second Wi-Fi driver of the router. The second Wi-Fi chip obtains the channel load of the working channel of the router according to the third acquisition request, and sends the channel load of the working channel to the second Wi-Fi driver. The second Wi-Fi driver sends the channel load to the second decision module. If it is determined that the channel load of the working channel is greater than or equal to the preset channel load threshold, that is, it is determined that the working channel load is high or the channel is busy, and the number of devices connected to the router is 1, the second decision module parses the switching channel from the switching instruction, sets the working channel of the router to the switching channel, restarts the router, and makes the router work on the new working channel, that is, the switching channel.

[0075] Step S310: The network device sends a channel setting success notification to the terminal device.

[0076] In one embodiment of the present application, reference Figure 5 As shown in the figure, after the router completes the setting of the working channel and restarts to take effect, it sends a notification of successful channel setting to the mobile phone.

[0077] Step S311, the terminal device responds to the channel setting success notification and sends an Ack response to the network device.

[0078] In one embodiment of the present application, the mobile phone responds to the channel setting success notification sent by the router and replies an Ack response to the router, indicating that the channel setting success notification has been received.

[0079] Step S312: The terminal device re-establishes a connection with the network device.

[0080] In one embodiment of the present application, the mobile phone interacts with the router in accordance with the interaction process of the detection frame, the authentication frame, the association frame and the dynamic host configuration protocol frame, and then re-establishes the Wi-Fi connection between the mobile phone and the router. The process of establishing a Wi-Fi connection between the mobile phone and the router can refer to the description of step S301, which will not be repeated here.

[0081] In another embodiment of the present application, in step S309, the network device parses the switching channel from the switching instruction sent by the terminal device, sets the working channel of the network device as the switching channel and sends a setting success notification to the terminal device. After sending the setting success notification, the network device restarts to make the set working channel take effect.

[0082] In the above embodiment, when the terminal device determines that the air interface quality of the working channel for communication connection with the network device is poor, it scans the interference values ​​of other channels and selects the channel with the smallest interference value as the switching channel. When it is determined that the terminal device has no user-perceivable service, it sends a channel switching instruction to the network device. The network device parses the switching channel from the switching instruction, sets the working channel of the network device to the switching channel, restarts the network device, and makes the network device work on the new working channel. After the terminal device reconnects to the network device, it communicates with the network device through the new working channel, thereby solving the problem of terminal device Internet access jamming and improving the user's Internet experience. In addition, in the above embodiment, by confirming the user-perceivable service, it can avoid the problem of the user being able to perceive the network disconnection that affects the Internet experience during the process of restarting the network device to set the channel due to the presence of user-perceivable service at the terminal device. The terminal device involved in the embodiment of the present application is introduced below.
