[0031] The embodiments of the present application provide a method, device, client, and storage medium for determining a wireless fidelity channel, which are used to determine a target channel based on interference information of multiple channels detected by a wireless access point device and at least one client, so as to switch to the target channel for communication. Because the target channel is not determined only based on the interference information of multiple channels detected by the wireless access point device, the communication distance covered is likely to be farther.

[0032] In order to make the technical personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiment of the present application will be described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, not all of the embodiments. Based on the embodiments in the present application, they should all fall within the scope of protection of the present application.

[0033] The following is a brief description of some terms involved in this application, as follows:

[0034] SoftAP (Software Access Point): usually refers to a wireless access point implemented by software, which is also commonly known as a WiFi hotspot. Unlike traditional hardware access points (AP), SoftAP is usually configured and controlled by software and can be implemented on WiFi-enabled devices such as smartphones, tablets or laptops. SoftAP allows the device to operate in AP mode, providing network access services, allowing other devices (such as smartphones, laptops, etc.) to connect to the device and access the Internet or other network resources through it. In SoftAP mode, the device can simulate the functions of a traditional hardware wireless router and provide the following services:

[0035] 1) Network sharing: Share the device's network connection (such as 4G or wired network) with other devices.

[0036] 2) Device connection: Allow other devices to connect to the SoftAP device via WiFi and access the Internet or other network resources.

[0037] 3) Data transmission: Realize data transmission and communication between devices without traditional wireless routers.

[0038] 4) Network management: SoftAP devices can manage connected clients, process network traffic, and perform some basic network management tasks, such as assigning IP addresses (Dynamic Host Configuration Protocol (DHCP)), Network Address Translation (NAT), etc.

[0039] Station (STA, Station Mode): Station mode refers to the device as a client in a wireless network, connecting to the wireless network and receiving signals from the AP. In this mode, the device is usually called a Station, and it connects to the AP to obtain network services. Devices in Station mode are responsible for sending and receiving wireless signals, performing network communication tasks, and exchanging data with other network devices. In a home or office environment, most wireless devices (such as smartphones, laptops, Internet of Things (IoT) devices, etc.) usually work in Station mode, and they are connected to a wireless router or SoftAP to access the network. In short, SoftAP is a software-defined wireless access point that is responsible for providing network services and managing network clients, while Station is a client device connected to a wireless network and is responsible for receiving and sending data. In a wireless network, SoftAP and Station work together to ensure smooth network communication.

[0040] Beamforming: An antenna technology that focuses wireless signals in a specific direction by adjusting the phase and amplitude of multiple antenna elements, thereby enhancing signal strength and reducing interference. This technology can improve the directionality of the signal, so that the signal is sent more concentratedly to the target receiver, thereby improving the quality of communication. At the chip level, beamforming may require complex hardware support, such as phase adjusters and amplitude adjusters, as well as digital signal processors (DSP) or field-programmable gate arrays (FPGA) to control these adjustments.

[0041] Maximum Ratio Combining (MRC) is a reception technology that combines signals from multiple antennas to improve the quality of signal reception. MRC uses signals from multiple receiving antennas and combines them to maximize the signal-to-noise ratio (SNR) through appropriate weight adjustment. This method can improve the interference information of the received signal, thereby improving the reception performance. At the chip level, MRC may require the implementation of complex signal processing algorithms and the hardware used to execute these algorithms, such as multiple-in multipleout (MIMO) processors.

[0042] Both technologies are designed to improve the performance of wireless communication systems, including the quality of signal transmission and reception. Beamforming focuses on signal enhancement at the transmitting end, while MRC focuses on signal merging at the receiving end. Implementing these technologies may require the addition of complex hardware to the chip, which may lead to an increase in chip cost. However, these technologies are crucial to improving the overall performance of wireless communication systems, especially in high-frequency bands and high data rate applications, such as 5G communication systems.

[0043] WiFi P2P (Peer-to-Peer) technology, also known as WiFi Direct, allows multiple WiFi devices to connect directly to each other without a wireless access point (AP). It supports the construction and communication of peer-to-peer networks (P2P Networks) between devices.

[0044] There are two ways to avoid interference channels when the WiFi chip of the current wireless access point device (such as a mobile phone or tablet) supports WiFi when turning on SoftAP or SoftAP is working, as shown below:

[0045] Method 1: When the SoftAP is started, the WiFi bottom layer on the SoftAP side will first detect the noise level of each channel within the available spectrum range in the environment to determine the interference level of each channel, and then select a channel with less interference as the working channel of the SoftAP.

[0046] Method 2: The WiFi bottom layer on the SoftAP side dynamically detects the interference changes of the current working channel and the interference of other channels within the available spectrum. If the interference of the current working channel is large and the interference of other channels is small, it will initiate a switch to the channel with less interference, allowing other connected clients (Stations) to switch to the channel with less interference at the same time.

[0047] A device that has SoftAP enabled can be called a wireless access point device. Figure 1A The figure shows a schematic diagram of SoftAP scanning the interference level of the wireless channels near it. When SoftAP selects a channel with low interference, it is the SoftAP's own detection, that is, the channel with the least interference to the SoftAP.

[0048] like Figure 1B As shown in the figure, it is a schematic diagram of the channel selected by SoftAP and the clients connected to it at different distances from SoftAP. Because the channel selected by SoftAP has the least interference to itself, when Station1 is close to SoftAP, the degree of external interference to Station1 is close to that of SoftAP, so the working channel at this time basically has the least interference to Station1. Figure 2 In the figure, there is also Station 2, which is far away from SoftAP. In addition, there are many other users near Station 2, which are access points (APs). If the working channel frequency of these APs is close to the working channel frequency of SoftAP, it will cause great interference to Station 2's reception, causing Station 2's network speed to drop sharply or even unable to use the network normally. This results in Station 2's communication performance dropping rapidly as long as it is slightly away from SoftAP, resulting in the SoftAP's effective communication coverage being too small.

[0049] In some implementations, most devices are trying to improve the transmission or reception performance when using SoftAP, so that the signal reaching a distant place is stronger or the weaker channel from a distant place can be effectively received. In order to improve the transmission or reception performance, it is necessary to add complex hardware to the physical layer of the chip, such as Beamforming or MRC, or add a higher power power amplifier. The cost of the chip has obviously increased a lot.

[0050] like Figure 1C As shown, it is a schematic diagram of a communication system used in an embodiment of the present application. The communication system includes a wireless access point device and at least one client. Among them, the at least one client is a client accessing a target wireless access point, and the target wireless access point is a wireless access point enabled by the wireless access point device. That is, the wireless access point device enables a SoftAP, and at least one client accesses the SoftAP.

[0051] In the embodiment of the present application, the wireless access point device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, etc.

[0052] In the embodiment of the present application, the client may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self driving, a wireless terminal device in remote medical, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home, etc.

[0053] As an example but not limitation, in the embodiments of the present application, the client may also be a wearable device. Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and fully or partially independent of smartphones, such as smart watches or smart glasses, as well as devices that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets and smart jewelry for vital sign monitoring.

[0054] In the embodiment of the present application, the target channel is determined by the interference information of multiple channels detected by the wireless access point device and the interference information of multiple channels detected by at least one client accessing the wireless access point device, so as to switch to the target channel for communication. Therefore, the target channel is determined by comprehensively considering the channel interference size of the wireless access point device and at least one client accessing the wireless access point device. Therefore, the target channel is not determined by only considering the interference information of multiple channels detected by the wireless access point device. In general, it is highly likely that longer-distance communication can be covered.

[0055] like Figure 2 FIG. 1 is a schematic diagram of an embodiment of a method for determining a wireless fidelity channel in an embodiment of the present application, wherein the method is applied to Figure 1C The communication system shown, the method comprising:

[0056] 201. The client detects and obtains interference information of multiple channels.

[0057] In the embodiments of the present application, both the wireless access point device and the client need to have the ability to detect interference information of multiple channels. Specifically, in the physical layer of the wireless fidelity chip, in addition to the wireless access point device being able to detect the interference level of each channel within the available frequency range, the client that accesses the wireless access point device to turn on the wireless access point must also implement this capability, that is, it can also realize continuous dynamic detection of the interference level between the current working channel and other channels. This capability is implemented by the wireless detection (radio sens) unit in the wireless fidelity firmware (or wireless fidelity chip). Figure 3A , which is a schematic diagram showing that a client in an embodiment of the present application includes a wireless detection unit.

[0058] The client includes a wireless fidelity chip (WiFi Chip), wherein the wireless fidelity chip includes a media access control (MAC) layer and a physical layer, the physical layer includes a transmit (TX) module and a receive (RX) module, and the receive module includes a radio sens unit. In wireless communication systems, "radio sens" usually refers to the sensitivity or sensitivity of wireless signals, which is an indicator of the minimum signal strength that a wireless receiver can detect. Sensitivity is usually expressed in decibel milliwatts (dBm), which defines the minimum effective signal power that a receiver can receive under specific interference information (Signal-to-Noise Ratio, SNR) conditions. High sensitivity means that the receiver can receive weaker signals, thereby improving the reliability and coverage of communications.

[0059] In some possible implementations, the interference information includes a signal-to-noise ratio.

[0060] Among them, the signal-to-noise ratio is the signal to interference plus noise ratio (Signal to Interference plus Noise Ratio), that is, the signal to interference plus noise ratio refers to the ratio of the received signal strength indication (Received Signal Strength Indication, RSSI) to the strength of the received interference signal (noise and interference); it can be simply understood as "signal-to-noise ratio".

[0061] Received Signal Strength Indicator (RSSI) is an important parameter in wireless communication, which indicates the strength of the received wireless signal. RSSI is usually measured in decibel milliwatts (dBm). The smaller the value (the more negative the value), the stronger the signal. The calculation of RSSI is usually based on the received signal power. In wireless communication, the device measures the received signal strength and converts it into a dBm value. For example, a signal strength of 1mW is represented as 0dBm, and a signal strength less than 1mW is represented as a negative dBm value.

[0062] In communication systems, noise generally refers to unwanted signals that appear during signal transmission, which interfere with or mask the original signal, thereby affecting the communication quality. Noise can come from a variety of sources, including but not limited to the following types:

[0063] Thermal noise: Noise caused by the thermal motion of internal electronic components (such as resistors) of electronic devices, also known as Johnson-Nyquist noise.

[0064] External noise: Noise from the external environment, such as electromagnetic interference (EMI), radio frequency interference (RFI), radio frequency noise, etc.

[0065] Channel noise: In wireless communications, channel noise refers to the various noises encountered during the propagation of wireless signals, which may be caused by multipath propagation, atmospheric absorption, reflection and scattering from buildings and other objects.

[0066] Equipment noise: Noise generated by devices used in communication systems, such as amplifiers, mixers, analog-to-digital converters (ADCs), etc.

[0067] Quantum noise: In some cases, such as in optical communication systems, quantum noise (such as photon noise) can also affect signal quality.

[0068] In the present technical solution, the signal-to-noise ratio can be used to intuitively indicate the degree of interference to a channel, thereby facilitating subsequent channel switching according to the signal-to-noise ratio.

[0069] In some possible implementations, the signal-to-noise ratio is inversely proportional to the degree of interference.

[0070] In the present technical solution, the signal-to-noise ratio can be used to characterize the interference degree of the corresponding channel. The signal-to-noise ratio is inversely proportional to the interference degree, so if the signal-to-noise ratio of a channel is larger, then the interference degree of the channel is lower, and if the signal-to-noise ratio of a channel is smaller, then the interference degree of the channel is higher. The signal-to-noise ratio can be used to intuitively indicate the interference degree of the channel, which is convenient for subsequent channel switching based on the signal-to-noise ratio.

[0071] Optionally, in some possible implementations, the interference information includes channel load.

[0072] Channel load refers to the degree to which a channel is occupied by data transmission within a certain period of time in a wireless communication network. It is usually used to measure the busyness of the network and is an important parameter for network performance optimization and resource allocation. The level of channel load directly affects network performance indicators such as throughput and latency. Channel load can be indicated by channel utilization.

[0073] In a wireless local area network (WLAN), the calculation formula for channel utilization involves the busy time of the channel, that is, the total length of time that the AP detects the presence of a signal on the channel, which includes the effective transmission time and the invalid time occupied by the interference signal. The higher the channel utilization, the better, because it involves the balance between user experience and resource allocation. It is generally believed that when the channel utilization is less than 60%, users can get a better Internet experience; when the channel utilization is higher, it may cause network congestion and increased latency. Therefore, in order to ensure user experience, the lower the channel utilization, the better. However, too low channel utilization also means that channel resources are not fully utilized, which may lead to a waste of network construction costs. Network construction and maintenance personnel should monitor channel utilization and reasonably deploy network resources according to actual business needs. When the channel utilization is too high, you can adopt optimization strategies such as configuring dynamic speed limit function, troubleshooting signal interference problems, and troubleshooting multicast or broadcast message flooding to the air interface.

[0074] In the present technical solution, the channel load can be used to intuitively indicate the degree of interference to the channel, thereby facilitating subsequent channel switching according to the channel load.

[0075] In some possible implementations, the channel load is proportional to the degree of interference.

[0076] In the present technical solution, the channel load can also be used to characterize the interference degree of the corresponding channel. If the channel load of a channel is larger, it means that the amount of data that can be transmitted is larger, then the interference degree of the channel is higher; if the channel load of a channel is smaller, it means that the amount of data that can be transmitted is smaller, then the interference degree of the channel is lower. The channel load can intuitively indicate the interference degree of the channel, which is convenient for subsequent channel switching according to the channel load.

[0077] Optionally, in some possible implementations, the interference information includes a signal-to-noise ratio and a channel load.

[0078] In the present technical solution, the signal-to-noise ratio and the channel load can be used to intuitively indicate the degree of interference to the channel, thereby facilitating subsequent channel switching according to the signal-to-noise ratio and the channel load.

[0079] 202. The client sends the interference information of the multiple channels to a wireless access point device, where the interference information of the multiple channels is used by the wireless access point device to determine a target channel so as to switch to the target channel for communication.

[0080] In some possible implementations, the client sending the interference information of the multiple channels to the wireless access point device may include:

[0081] The client sends the interference information of the multiple channels to the wireless access point device through a chip communication protocol in the wireless fidelity chip; or,

[0082] The client sends the interference information of the multiple channels to the wireless access point device through a wireless fidelity application layer communication protocol.

[0083] For example, a communication protocol format is set in the wireless fidelity chip of the wireless access point device and the client (Station), which can also be called the wireless fidelity firmware. The client can directly transmit the interference information of multiple channels detected to the wireless access point device through the communication protocol. Figure 3B , which is a schematic diagram of transmitting interference information of multiple channels through a chip communication protocol in a wireless fidelity chip in an embodiment of the present application.

[0084] In this technical solution, the interference detection of each channel is realized through the Station, and the interference information (RSSI / Noise) of each channel is detected. The interference information of each channel can be exchanged through the communication protocol at the bottom layer of the wireless fidelity chip, so that the wireless access point device can obtain the interference information of each channel of each Station. In this way, the wireless access point device can subsequently determine the target channel through the interference information of multiple channels of at least one client and the interference information of multiple channels detected by the wireless access point device, and perform subsequent channel switching, etc., which provides a data basis for determining the target channel.

[0085] In some possible implementations, the WiFi communication protocol standard includes the chip communication protocol.

[0086] In the present technical solution, the chip communication protocol can be defined as a protocol standard and incorporated into the WiFi standard to facilitate the transmission of channel interference information and improve the transmission efficiency of channel interference information.

[0087] For example, based on the existing WiFi communication protocol standard, the interference information of each channel of the Station can be transmitted to the wireless access point device through a self-developed application, so that the wireless access point device can obtain the interference information of each channel of each Station. Figure 3C , which is a schematic diagram of transmitting interference information of multiple channels through a wireless fidelity application layer communication protocol in an embodiment of the present application.

[0088] In the present technical solution, interference detection of each channel is implemented through Station, and interference information (RSSI / Noise) of each channel is detected. The client can send the interference information of each channel to the wireless access point device through the application, so that the wireless access point device can subsequently determine the target channel through the interference information of multiple channels of at least one client and the interference information of multiple channels detected by the wireless access point device, and perform subsequent channel switching, etc., thereby providing a data basis for determining the target channel.

[0089] In some possible implementations, the client detecting and obtaining interference information of multiple channels may include: the client detecting and obtaining interference information of multiple channels through a wireless detection unit of a physical layer in a wireless fidelity chip; and sending the interference information of the multiple channels to an application layer;

[0090] The client sends the interference information of the multiple channels to the wireless access point device through the wireless fidelity application layer communication protocol, which may include: the client controls the application program in the application layer through a processor to send the interference information of the multiple channels to the wireless access point device.

[0091] Exemplarily, the client and the wireless access point device include a wireless fidelity chip and a processor, which may also be referred to as a main control processor. The client detects interference information of multiple channels through the radio sensor unit of the physical layer in the wireless fidelity chip, and then sends it to the upper layer, specifically to the application layer. Then, after receiving the interference information of the multiple channels, the application layer controls the first target application in the application layer through the processor to send the interference information of the multiple channels to the wireless access point device. The wireless access point device may also receive the interference information of the multiple channels sent by the client through the second target application in the application layer. Generally speaking, the first target application in the client and the second target application in the wireless access point device are of the same type, but in some cases, when the types of the first target application and the second target application are different, the interference information of multiple channels may also be transmitted, which is not specifically limited in the embodiments of the present application.

[0092] In this technical solution, a specific implementation method is provided for the client to send the interference information of the multiple channels to the wireless access point device through the wireless fidelity application layer communication protocol. Specifically, the processor controls the application program in the application layer to send the interference information of the multiple channels to the wireless access point device, thereby improving the feasibility of the solution.

[0093] exist Figure 3B and Figure 3C As shown, the processor and the wireless fidelity WiFi chip are connected via a communication interface.

[0094] 203. The wireless access point device obtains interference information of multiple channels detected by the wireless access point device and at least one client, where the at least one client is a client accessing a target wireless access point, and the target wireless access point is a wireless access point enabled by the wireless access point device.

[0095] In some possible implementations, the wireless access point device obtains interference information of multiple channels of the wireless access point device and at least one client, which may include: the wireless access point device obtains the interference information of multiple channels of the wireless access point device through the access pointless device; and the wireless access point device receives the interference information of multiple channels sent by the at least one client.

[0096] Take interference information including signal-to-noise ratio as an example. There are 5 channels in the frequency range corresponding to the wireless access point, that is, the WiFi hotspot, turned on by the wireless access point device. The wireless access point device can detect the signal-to-noise ratio of these 5 channels. At the same time, at least one client accessing the wireless access point will also detect the signal-to-noise ratio of these 5 channels, and then send the signal-to-noise ratio of these 5 channels to the wireless access point device. It is assumed here that the number of at least one client is 3, including UE (User Equipment, user equipment, also called client) 1, UE2 and UE3.

[0097] The signal-to-noise ratios of the five channels detected by the wireless access point device are:

[0098] The signal-to-noise ratio of channel 1 is 1, the signal-to-noise ratio of channel 2 is 3.5, the signal-to-noise ratio of channel 3 is 3, the signal-to-noise ratio of channel 4 is 4, and the signal-to-noise ratio of channel 5 is 2;

[0099] The signal-to-noise ratios of the five channels detected by the three clients are:

[0100] UE1: The signal-to-noise ratio of channel 1 is 1.2, the signal-to-noise ratio of channel 2 is 3.7, the signal-to-noise ratio of channel 3 is 2.1, the signal-to-noise ratio of channel 4 is 4.5, and the signal-to-noise ratio of channel 5 is 3;

[0101] UE2: The signal-to-noise ratio of channel 1 is 4, the signal-to-noise ratio of channel 2 is 5, the signal-to-noise ratio of channel 3 is 3.1, the signal-to-noise ratio of channel 4 is 3, and the signal-to-noise ratio of channel 5 is 1;

[0102] UE3: The signal-to-noise ratio of channel 1 is 5, the signal-to-noise ratio of channel 2 is 4, the signal-to-noise ratio of channel 3 is 3, the signal-to-noise ratio of channel 4 is 3.5, and the signal-to-noise ratio of channel 5 is 4.

[0103] Take the interference information including channel load, and the channel load is indicated by channel utilization as an example. There are 5 channels in the frequency range corresponding to the wireless access point, that is, the WiFi hotspot, turned on by the wireless access point device. The wireless access point device can detect the channel utilization of these 5 channels. At the same time, at least one client accessing the wireless access point will also detect the channel utilization of these 5 channels, and then send the channel utilization of these 5 channels to the wireless access point device. It is assumed here that the number of at least one client is 3, including UE (User Equipment, user equipment, also called client) 1, UE2 and UE3.

[0104] The channel utilization rates of the five channels detected by the wireless access point device are:

[0105] The channel utilization rate of channel 1 is 80%, the channel utilization rate of channel 2 is 30%, the channel utilization rate of channel 3 is 40%, the channel utilization rate of channel 4 is 20%, and the channel utilization rate of channel 5 is 60%;

[0106] The channel utilization rates of the five channels detected by the three clients are:

[0107] UE1: The channel utilization of channel 1 is 76%, the channel utilization of channel 2 is 36%, the channel utilization of channel 3 is 58%, the channel utilization of channel 4 is 12%, and the channel utilization of channel 5 is 40%;

[0108] UE2: The channel utilization of channel 1 is 20%, the channel utilization of channel 2 is 10%, the channel utilization of channel 3 is 38%, the channel utilization of channel 4 is 40%, and the channel utilization of channel 5 is 80%;

[0109] UE3: The channel utilization of channel 1 is 90%, the channel utilization of channel 2 is 20%, the channel utilization of channel 3 is 40%, the channel utilization of channel 4 is 30%, and the channel utilization of channel 5 is 80%.

[0110] In this technical solution, a specific implementation method is provided for a wireless access point device to obtain interference information (such as signal-to-noise ratio and channel load) of multiple channels of the wireless access point device and at least one client, thereby improving the feasibility of the solution.

[0111] In some possible implementations, the wireless access point device receives the interference information of multiple channels sent by the at least one client, which may include: the wireless access point device receives the interference information of multiple channels sent by the at least one client through a chip communication protocol in a wireless fidelity chip; or the wireless access point device receives the interference information of multiple channels sent by the at least one client through an application layer communication protocol of wireless fidelity.

[0112] It should be noted that the wireless access point device receives the interference information of multiple channels sent by the at least one client through the chip communication protocol in the wireless fidelity chip; or, through the application layer communication protocol of wireless fidelity, the wireless access point device receives the interference information of multiple channels sent by the at least one client. Please refer to the description of the client sending the interference information of multiple channels above, which will not be repeated here.

[0113] In this technical solution, different implementation modes are provided for a wireless access point device to receive interference information of multiple channels sent by a client, so that different transmissions of interference information of multiple channels can be selected according to actual needs, thereby improving the feasibility of the solution.

[0114] In some possible implementations, the wireless network corresponding to the wireless access point enabled by the wireless access point device may be a WiFi network to which the wireless access point device is connected, or may be mobile data of the wireless access point device, which is not specifically limited in the embodiments of the present application.

[0115] 204. The wireless access point device determines a target channel according to interference information of multiple channels detected by the wireless access point device and at least one client, so as to switch to the target channel for communication.

[0116] In some possible implementations, the interference information includes a signal-to-noise ratio; the wireless access point device determines the target channel according to the interference information of multiple channels detected by the wireless access point device and at least one client, which may include: the wireless access point device determines a first intersection channel whose signal-to-noise ratio is greater than a preset signal-to-noise ratio threshold among the signal-to-noise ratios of multiple channels of the wireless access point device and at least one client; the wireless access point device determines the target channel according to multiple signal-to-noise ratios corresponding to each channel in the first intersection channel, so as to switch to the target channel for communication.

[0117] Exemplarily, assuming that the preset signal-to-noise ratio threshold is 2.9, the first intersection channels of the signal-to-noise ratios of the five channels detected by the wireless access point device and the signal-to-noise ratios of the five channels detected by the three clients are: channel 2 and channel 4.

[0118] For channel 2, the signal-to-noise ratio detected by the wireless access point device is 3.5, the signal-to-noise ratio detected by UE1 is 3.7, the signal-to-noise ratio detected by UE2 is 5, and the signal-to-noise ratio detected by UE3 is 4.

[0119] For channel 4: the signal-to-noise ratio detected by the wireless access point device is 4, the signal-to-noise ratio detected by UE1 is 4.5, the signal-to-noise ratio detected by UE2 is 3, and the signal-to-noise ratio detected by UE3 is 3.5.

[0120] Then, according to the signal-to-noise ratio corresponding to the first intersection channel, for example, channel 2 and channel 4 here, the target channel is determined.

[0121] In the present technical solution, the wireless access point device can determine the target channel according to multiple signal-to-noise ratios corresponding to each channel in the first intersection channel, so as to switch to the target channel for communication. Since the target channel is the first intersection channel whose signal-to-noise ratio is greater than a preset signal-to-noise ratio threshold, determined by the wireless access point device among the signal-to-noise ratios of multiple channels of the wireless access point device and at least one client, the target channel is determined by the signal-to-noise ratio corresponding to the first intersection channel whose signal-to-noise ratio is greater than the preset signal-to-noise ratio threshold. Therefore, the selected target channel is not particularly interfered with, and the communication distance covered can be relatively far.

[0122] In some possible implementations, the signal-to-noise ratios of multiple channels of the wireless access point device in the wireless access point device and at least one client, or multiple signal-to-noise ratios corresponding to each channel in the first intersection channel, may be in the form of a list.

[0123] In some possible implementations, if the first intersection channel cannot be obtained from the signal-to-noise ratios of multiple channels of the wireless access point device and the at least one client according to a preset signal-to-noise ratio threshold, the preset signal-to-noise ratio threshold can be lowered, and then the first intersection channel can be obtained from the signal-to-noise ratios of multiple channels of the wireless access point device and the at least one client according to the lowered preset signal-to-noise ratio threshold, and the target channel is determined according to the signal-to-noise ratio corresponding to the first intersection channel.

[0124] In the present technical solution, if the first intersection channel cannot be obtained according to the preset signal-to-noise ratio threshold, the preset signal-to-noise ratio threshold can be lowered, and the first intersection channel can be obtained according to the lowered preset signal-to-noise ratio threshold, so as to perform subsequent processing to determine the target channel, thereby improving the feasibility of the solution.

[0125] In some possible implementations, the target channel is a channel with a minimum signal-to-noise ratio among target signal-to-noise ratios corresponding to each channel in the first intersection channels, and the target signal-to-noise ratio corresponding to each channel is a maximum signal-to-noise ratio among multiple signal-to-noise ratios corresponding to each channel.

[0126] For example, for channel 2, the signal-to-noise ratio detected by the wireless access point device is 3.5, the signal-to-noise ratio detected by UE1 is 3.7, the signal-to-noise ratio detected by UE2 is 5, and the signal-to-noise ratio detected by UE3 is 4. Then, the maximum signal-to-noise ratio corresponding to channel 2 is 5.

[0127] For channel 4: the signal-to-noise ratio detected by the wireless access point device is 4, the signal-to-noise ratio detected by UE1 is 4.5, the signal-to-noise ratio detected by UE2 is 3, and the signal-to-noise ratio detected by UE3 is 3.5. Therefore, the maximum signal-to-noise ratio corresponding to channel 4 is 4.5.

[0128] Then, among the maximum signal-to-noise ratios corresponding to channel 2 and channel 4, the channel with the minimum signal-to-noise ratio is channel 4, so the target channel is channel 4.

[0129] In this technical solution, because the target channel is the channel with the minimum channel ratio among the maximum signal-to-noise ratio corresponding to the first intersection channel, the selected target channel is not particularly interfered with and the communication distance covered can be relatively far.

[0130] In some possible implementations, the target channel is a channel with a maximum signal-to-noise ratio among target signal-to-noise ratios corresponding to each channel in the first intersection channels, and the target signal-to-noise ratio corresponding to each channel is a maximum signal-to-noise ratio among multiple signal-to-noise ratios corresponding to each channel.

[0131] For example, for channel 2, the signal-to-noise ratio detected by the wireless access point device is 3.5, the signal-to-noise ratio detected by UE1 is 3.7, the signal-to-noise ratio detected by UE2 is 5, and the signal-to-noise ratio detected by UE3 is 4. Then, the maximum signal-to-noise ratio corresponding to channel 2 is 5.

[0132] For channel 4: the signal-to-noise ratio detected by the wireless access point device is 4, the signal-to-noise ratio detected by UE1 is 4.5, the signal-to-noise ratio detected by UE2 is 3, and the signal-to-noise ratio detected by UE3 is 3.5. Therefore, the maximum signal-to-noise ratio corresponding to channel 4 is 4.5.

[0133] Then, among the maximum signal-to-noise ratios corresponding to channel 2 and channel 4, the channel with the maximum signal-to-noise ratio is channel 2, so the target channel is channel 2.

[0134] In this technical solution, because the target channel is the channel with the maximum channel ratio among the maximum signal-to-noise ratios corresponding to the first intersection channel, the selected target channel is least interfered with and can cover a relatively longer communication distance.

[0135] In some possible implementations, the target channel is a channel having the largest average signal-to-noise ratio among average signal-to-noise ratios corresponding to each channel in the first intersection channels.

[0136] For example, for channel 2, the signal-to-noise ratio detected by the wireless access point device is 3.5, the signal-to-noise ratio detected by UE1 is 3.7, the signal-to-noise ratio detected by UE2 is 5, and the signal-to-noise ratio detected by UE3 is 4. Then, the average signal-to-noise ratio corresponding to channel 2 is 4.05.

[0137] For channel 4: the signal-to-noise ratio detected by the wireless access point device is 4, the signal-to-noise ratio detected by UE1 is 4.5, the signal-to-noise ratio detected by UE2 is 3, and the signal-to-noise ratio detected by UE3 is 3.5. Therefore, the average signal-to-noise ratio corresponding to channel 4 is 3.75.

[0138] Then, among the average signal-to-noise ratios corresponding to channel 2 and channel 4, the channel with the largest average signal-to-noise ratio is channel 2, so the target channel is channel 2.

[0139] In this technical solution, because the target channel is the channel with the largest average channel ratio among the average signal-to-noise ratios corresponding to the first intersection channels, the selected target channel is subject to the smallest degree of interference on average, so the covered communication distance can be relatively far.

[0140] In some possible implementations, the interference information includes a channel load; the wireless access point device determines a target channel according to the interference information of multiple channels detected by the wireless access point device and at least one client, which may include: the wireless access point device determines, among the channel loads of multiple channels of the wireless access point device and at least one client, a second intersection channel whose channel load is less than, equal to, or greater than a preset load threshold; the wireless access point device determines the target channel according to multiple channel loads corresponding to each channel in the second intersection channel, so as to switch to the target channel for communication.

[0141] Exemplarily, assuming that the preset channel utilization is 40%, the intersection of the channel utilization of 5 channels detected by the wireless access point device and the channel utilization of 5 channels detected by 3 clients is: channel 2 and channel 4.

[0142] For channel 2: the channel utilization rate detected by the wireless access point device is 30%, the signal-to-noise ratio detected by UE1 is 36%, the signal-to-noise ratio detected by UE2 is 10%, and the signal-to-noise ratio detected by UE3 is 20%.

[0143] For channel 4: the signal-to-noise ratio detected by the wireless access point device is 20%, the signal-to-noise ratio detected by UE1 is 12%, the signal-to-noise ratio detected by UE2 is 40%, and the signal-to-noise ratio detected by UE3 is 30%.

[0144] Then, according to the second intersection channel, for example, the channel utilization rates corresponding to channel 2 and channel 4 here, the target channel is determined.

[0145] In the present technical solution, the wireless access point device can determine the target channel according to the multiple channel loads corresponding to each channel in the second intersection channel, so as to switch to the target channel for communication. Because the target channel is the second intersection channel whose channel load is less than or equal to a preset load threshold value determined by the wireless access point device among the channel loads of the multiple channels of the wireless access point device and at least one client, the target channel is determined by the channel load corresponding to the second intersection channel whose channel load is less than or equal to a preset load threshold value. Therefore, the selected target channel is not particularly subject to interference and the communication distance covered can be relatively far.

[0146] In some possible implementations, the channel loads of multiple channels of the wireless access point device and at least one client, or the multiple channel loads corresponding to each channel in the second intersection channels, may be in the form of a list.

[0147] In some possible implementations, if, according to a preset load threshold, the second intersection channel cannot be obtained in the channel loads of multiple channels of the wireless access point device and at least one client, the preset load threshold can be lowered, and then according to the lowered preset load threshold, the second intersection channel can be obtained in the channel loads of multiple channels of the wireless access point device and at least one client, and the target channel can be determined according to the channel load corresponding to the second intersection channel.

[0148] In the present technical solution, if the second intersection channel cannot be obtained according to the channel load, the preset load threshold can be lowered, and the second intersection channel can be obtained according to the lowered preset load threshold, so as to perform subsequent processing to determine the target channel, thereby improving the feasibility of the solution.

[0149] In some possible implementations, the target channel is a channel with a minimum channel load among the target channel loads corresponding to each channel in the second intersection channels, and the target channel load corresponding to each channel is a minimum channel load among multiple channel loads corresponding to each channel.

[0150] For example, for channel 2, the channel utilization rate detected by the wireless access point device is 30%, the signal-to-noise ratio detected by UE1 is 36%, the signal-to-noise ratio detected by UE2 is 10%, and the signal-to-noise ratio detected by UE3 is 20%. Then, the minimum channel utilization rate corresponding to channel 2 is 10%.

[0151] For channel 4: the signal-to-noise ratio detected by the wireless access point device is 20%, the signal-to-noise ratio detected by UE1 is 12%, the signal-to-noise ratio detected by UE2 is 40%, and the signal-to-noise ratio detected by UE3 is 30%. Then, the minimum channel utilization corresponding to channel 4 is 12%.

[0152] Because the minimum channel utilization rate corresponding to channel 2 is 10% and the minimum channel utilization rate corresponding to channel 4 is 12%, the channel corresponding to the minimum channel utilization rate between channel 2 and channel 4 is channel 2, and therefore, channel 2 is the target channel.

[0153] In this technical solution, because the target channel is the channel with the minimum channel load among the minimum channel loads corresponding to the second intersection channel, the selected target channel is not particularly susceptible to interference and the communication distance covered can be relatively far.

[0154] In some possible implementations, the target channel is a channel having the smallest average channel load among the average channel loads corresponding to each channel in the second intersection channels.

[0155] For example, for channel 2: the channel utilization rate detected by the wireless access point device is 30%, the signal-to-noise ratio detected by UE1 is 36%, the signal-to-noise ratio detected by UE2 is 10%, and the signal-to-noise ratio detected by UE3 is 20%. Then, the average channel utilization rate corresponding to channel 2 is 24%.

[0156] For channel 4: the signal-to-noise ratio detected by the wireless access point device is 20%, the signal-to-noise ratio detected by UE1 is 12%, the signal-to-noise ratio detected by UE2 is 40%, and the signal-to-noise ratio detected by UE3 is 30%. Then, the average channel utilization corresponding to channel 4 is 25.5%.

[0157] Here, the average channel utilization rate corresponding to channel 2 is 24%, and the average channel utilization rate corresponding to channel 4 is 25.5%. Therefore, the channel with the smallest average channel utilization rate is channel 2, so the target channel is channel 2.

[0158] In this technical solution, because the target channel is the channel with the smallest average channel load among the average channel loads corresponding to the second intersection channels, the degree of interference to the selected target channel is the smallest on average, so the covered communication distance can be relatively far.

[0159] In some possible implementations, the interference information includes a signal-to-noise ratio and a channel load; the wireless access point device determines a target channel according to the interference information of multiple channels detected by the wireless access point device and at least one client, which may include: the wireless access point device determines a first intersection channel whose signal-to-noise ratio is greater than a preset signal-to-noise ratio threshold among the signal-to-noise ratios of multiple channels of the wireless access point device and at least one client; the wireless access point device determines a second intersection channel whose channel load is less than, equal to, and greater than a preset load threshold among the channel loads of multiple channels of the wireless access point device and at least one client; the wireless access point device determines a target channel according to the first intersection channel and the second intersection channel, so as to switch to the target channel for communication.

[0160] In the present technical solution, in the present technical solution, the wireless access point device can determine the target channel according to the first intersection channel and the second intersection channel to switch to the target channel for communication, and the first intersection channel is an intersection channel whose signal-to-noise ratio is greater than a preset signal-to-noise ratio threshold, and the second intersection channel is an intersection channel whose channel load is less than or equal to a preset load threshold, so that the selected target channel is not particularly interfered with, and the communication distance covered can be relatively far.

[0161] In some possible implementations, the wireless access point device determines a target channel according to the first intersection channel and the second intersection channel to switch to the target channel for communication, which may include: when the wireless access point device determines a target intersection channel of the first intersection channel and the second intersection channel, determining a target channel according to the target intersection channel to switch to the target channel for communication.

[0162] In this technical solution, the wireless access point device can determine the intersection channel of the first intersection channel and the second intersection channel as the target intersection channel, and determine the target channel in the target intersection channel. Because the target intersection channel takes the signal-to-noise ratio and the channel load into consideration, the determined target channel is not particularly subject to interference, and the communication distance covered can be relatively far.

[0163] In some possible implementations, the target channel is any channel in the target intersection channels.

[0164] In some possible implementations, the target channel is a channel with the smallest signal-to-noise ratio, a channel with the largest signal-to-noise ratio, or a channel with the largest average signal-to-noise ratio, or a channel with the smallest channel load, or a channel with the smallest average channel load among the target intersection channels.

[0165] In this technical solution, several implementation methods for determining the target channel in the target intersection channel are provided, which improves the feasibility of the solution. Because the target intersection channel takes the signal-to-noise ratio and channel load into consideration, the interference degree of the determined target channel is not particularly large, and the communication distance covered can be relatively far.

[0166] In some possible implementations, the wireless access point device determines the target channel based on the first intersection channel and the second intersection channel to switch to the target channel for communication, which may include: the wireless access point device determines the target channel based on multiple signal-to-noise ratios corresponding to each channel in the first intersection channel and multiple channel loads corresponding to each channel in the second intersection channel to switch to the target channel for communication.

[0167] In the present technical solution, the wireless access point device can determine the target channel according to the multiple signal-to-noise ratios corresponding to each channel in the first intersection channel and the multiple channel loads corresponding to each channel in the second intersection channel, so as to switch to the target channel for communication, and the first intersection channel is an intersection channel whose signal-to-noise ratio is greater than a preset signal-to-noise ratio threshold, and the second intersection channel is an intersection channel whose channel load is less than or equal to a preset load threshold, so that the selected target channel is not particularly interfered with, and the communication distance covered can be relatively far.

[0168] In some possible implementations, the wireless access point device determines the target channel according to a plurality of signal-to-noise ratios corresponding to each channel in the first intersection channel and a plurality of channel loads corresponding to each channel in the second intersection channel, including: the wireless access point device determines the first target channel according to the plurality of signal-to-noise ratios corresponding to each channel in the first intersection channel, and determines the second target channel according to the plurality of channel loads corresponding to each channel in the second intersection channel; determines the target channel according to the intersection of the first target channel and the second target channel;

[0169] The first target channel is a channel with a minimum signal-to-noise ratio among the maximum signal-to-noise ratios corresponding to each channel in the first intersection channels; or, the first target channel is a channel with a maximum signal-to-noise ratio among the target signal-to-noise ratios corresponding to each channel in the first intersection channels; or, the first target channel is a channel with a maximum average signal-to-noise ratio among the average signal-to-noise ratios corresponding to each channel in the first intersection channels, and the target signal-to-noise ratio corresponding to each channel is the maximum signal-to-noise ratio among multiple signal-to-noise ratios corresponding to each channel;

[0170] The second target channel is the channel with the smallest channel load among the target channel loads corresponding to each channel in the second intersection channels; or, the target channel is the channel with the smallest average channel load among the average channel loads corresponding to each channel in the second intersection channels; the target channel load corresponding to each channel is the smallest channel load among the multiple channel loads corresponding to each channel.

[0171] In the present technical solution, the wireless access point device can determine the target channel according to the multiple signal-to-noise ratios corresponding to each channel in the first intersection channel and the multiple channel loads corresponding to each channel in the second intersection channel, so as to switch to the target channel for communication, and the first intersection channel is an intersection channel whose signal-to-noise ratio is greater than a preset signal-to-noise ratio threshold, and the second intersection channel is an intersection channel whose channel load is less than or equal to a preset load threshold, so that the selected target channel is not particularly interfered with, and the communication distance covered can be relatively far.

[0172] It should be noted that in the above implementation of determining the target channel, there may be multiple target channels. If there are multiple target channels, one may be randomly selected as the target channel to be switched.

[0173] In some possible implementations, the method is applied in a scenario of enabling a wireless fidelity WiFi hotspot, or an application scenario of WiFi peer-to-peer P2P.

[0174] In the technical solution, the method for determining the wireless fidelity channel can be applied to the application scenario of opening a wireless fidelity WiFi hotspot, or the application scenario of WiFi peer-to-peer P2P. Thus, the target channel can be determined based on the interference information of multiple channels detected by the wireless access point device and at least one client, so as to switch to the target channel for communication. Because the target channel is not determined only based on the interference information of multiple channels detected by the wireless access point device, the communication distance covered is likely to be farther.

[0175] In some possible implementations, the method may further include: switching to the target channel to communicate with the at least one client.

[0176] In this technical solution, a technical solution is proposed to avoid channels with large interference and comprehensively select channels with small interference to achieve long-distance communication coverage. After the target channel is determined, the wireless access point device initiates channel switching according to the existing communication standard protocol and switches to the target channel for communication, thereby improving the communication rate of the client at a long distance.

[0177] In an embodiment of the present application, through the interaction between the wireless access point device and each client (Station), a working channel with a better interference degree to each Station is selected to avoid the situation where the remote Station is extremely low in communication rate or unable to communicate due to interference from the same frequency or adjacent frequency nearby. That is, it is proposed that the wireless access point device integrates its own interference information and the interference information of each channel of all connected Stations to determine the better working channel for all connected Stations, so as to effectively avoid interference, improve communication rate and reduce communication delay. In particular, the communication rate of the remote Station can be greatly improved, thereby reducing communication delay. For example: when the Station is watching a video or a live broadcast, it frequently receives interference channels from other nearby access points, and the interference signal is much larger than the working channel of the wireless access point device, which causes the Station to effectively demodulate the data packets from the wireless access point device, resulting in serious freezes in the video or live broadcast. The problem of freezes in video or live broadcast can be effectively improved through the technical solution of the present application.

[0178] like Figure 4 FIG. 1 is a schematic diagram of an embodiment of a wireless access point device in an embodiment of the present application, which may include:

[0179] An acquisition module 401 is used to acquire interference information of multiple channels detected by the wireless access point device and at least one client, wherein the at least one client is a client accessing a target wireless access point, and the target wireless access point is a wireless access point enabled by the wireless access point device;

[0182] In some possible implementations, the target channel is a channel with a minimum signal-to-noise ratio among target signal-to-noise ratios corresponding to each channel in the intersection channels, and the target signal-to-noise ratio corresponding to each channel is a maximum signal-to-noise ratio among multiple signal-to-noise ratios corresponding to each channel, or,

[0194] The sending module 502 is specifically configured to send the interference information of the multiple channels to the wireless access point device through a wireless fidelity application layer communication protocol.

[0195] like Figure 6 FIG. 1 is a schematic diagram of another embodiment of a wireless access point device in an embodiment of the present application. Figure 6 The following is a detailed introduction to the various components of the mobile phone in the wireless access point device:

[0196] The RF circuit 610 can be used for receiving and sending signals during the process of sending and receiving information or making calls. In particular, after receiving the downlink information of the base station, it is sent to the processor 680 for processing; in addition, the designed uplink data is sent to the base station. Generally, the RF circuit 610 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (Low Noise Amplifier, LNA), a duplexer, etc. In addition, the RF circuit 610 can also communicate with the network and other devices through wireless communication.

[0197] The memory 620 can be used to store software programs and modules. The processor 680 executes various functional applications and data processing of the mobile phone by running the software programs and modules stored in the memory 620.
