[0058] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0059] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0060] refer to Figure 1 , Figure 1 A schematic flow chart of a channel switching method provided in an embodiment of the present application. A channel switching method provided in this embodiment includes the following steps:

[0061] S101: When a target device operates on a first channel, channel information corresponding to a plurality of channels in a network environment around the target device is determined.

[0062] In this embodiment, the target device may be a router, and the specific form of the target device may be selected according to actual needs. The specific form of the target device is not limited in this embodiment. Since there are multiple channels in the network environment around the target environment, if the channel on which the target device works is not good, it will affect the wireless network of the subsequent target device. Therefore, in order to avoid the above problem, the traditional method can switch the channel of the target device based on the channel information of each channel displayed by the target device, so that the target device works on the best channel. However, the above-mentioned manual channel switching has the problem of inaccurate channel switching and low efficiency. Therefore, in order to solve the above problem, when the target device works on the first channel, the channel information corresponding to multiple channels in the network environment around the target device is determined, so that the best channel is automatically determined from the multiple channels according to the channel information corresponding to the multiple channels in the network environment around the target device, and then the channel of the target device is automatically switched, so that the target device works on the determined best channel, which not only improves the accuracy of channel switching, but also improves the efficiency of channel switching.

[0063] The first channel is the channel on which the current target device is working. The channel information corresponding to each channel is composed of access point information corresponding to each wireless access point (AP) in the channel. The access point information may include the signal strength of the wireless access point, the channel where the wireless access point is located, and the channel adjacent to the channel where the wireless access point is located.

[0064] S102: For each channel, determine a first interference degree corresponding to the channel according to channel information corresponding to the channel.

[0065] In this embodiment, the first interference degree represents the interference degree of the channel to the wireless network of the target device. After obtaining the channel information corresponding to multiple channels in the network environment around the target device, for each channel, the first interference degree corresponding to the channel can be determined according to each access point information in the channel information corresponding to the channel, so as to switch the channel of the target device by using the determined first interference degree corresponding to each channel, so as to switch the first channel to the determined channel, so that the target device works on the determined channel.

[0066] S103: Determine a second channel from the multiple channels according to the first interference levels corresponding to the multiple channels.

[0067] In this embodiment, the second channel is used for channel switching of the target device. After obtaining the first interference levels corresponding to multiple channels in the network environment around the target device, a channel with the least interference to the wireless network of the target device can be selected from the multiple first interference levels determined, and the determined channel can be determined as the best channel (i.e., the second channel), so that when the target device is switched to the second channel for operation, the interference to the wireless network of the target device can be minimized, thereby improving the performance of the wireless network of the target device and improving the user experience.

[0068] S104: Switch the target device from the first channel to the second channel to operate.

[0069] In this embodiment, if the determined second channel is the same as the first channel, the target device does not need to be switched to the second channel, and the target device can continue to work on the first channel. If the determined second channel is different from the first channel, the first channel needs to be switched to the second channel so that the target device works on the second channel, thereby ensuring the performance of the wireless network of the target device, not only improving the accuracy of channel switching, but also improving the efficiency of channel switching.

[0070] The present embodiment provides a channel switching method. When a target device is operating on a first channel, the interference degree of each channel to the wireless network of the target device is determined by channel information corresponding to multiple channels in the surrounding environment of the target device, so as to determine the best second channel from the multiple channels according to the determined interference degrees, and then automatically switch the target device to the second channel for operation, thereby avoiding the problems of inaccurate and low efficiency of channel switching when manually switching the second channel, and improving the accuracy and efficiency of channel switching.

[0071] refer to Figure 2 , Figure 2 A schematic flow chart of another channel switching method provided in this embodiment. A channel switching method provided in this embodiment includes the following steps:

[0072] S201: When the target device operates on a first channel, channel information corresponding to a plurality of channels in a network environment around the target device is determined.

[0073] In this embodiment, determining the channel information corresponding to multiple channels in the network environment around the target device in step S201 includes:

[0074] When the target device is operating on the first channel, each wireless access point in the network environment around the target device is scanned to obtain access point information corresponding to each wireless access point;

[0075] Classifying all wireless access points in the same channel into one category according to access point information corresponding to all wireless access points, so as to obtain multiple classification results;

[0076] For each classification result, the access point information corresponding to all wireless access points in the classification result is determined as the channel information corresponding to the channel in the classification result, so as to obtain the channel information corresponding to the plurality of channels.

[0077] Among them, in order to make the target device work in the best channel in the network environment around the target to ensure the performance of the wireless network of the target device, when the target device works in the first channel, the wifi module set in the target device can be used to scan the various wireless access points in the network environment around the target device in real time, so as to obtain the access point information corresponding to each wireless access point. The access point information can refer to the above description, which is not repeated in this embodiment. The scanning of various wireless access points in the network environment around the target device by the wifi module can refer to the existing technology, which is not repeated in this embodiment.

[0078] Specifically, after obtaining access point information corresponding to each wireless access point in the network environment around the target device, all wireless access points in the network environment around the target device can be classified based on the channel where the wireless access point in each access point information is located, so as to classify all wireless access points in the same channel into one category, thereby obtaining multiple classification results. Among them, all wireless access points in each classification result are in the same channel. After obtaining multiple classification results, for each classification result, the access point information corresponding to all wireless access points in the classification result can be determined as the channel information corresponding to the channel in the classification result, thereby obtaining channel information corresponding to multiple channels in the network environment around the target device.

[0079] S202: performing the following operations for each channel: for each wireless access point in the channel, determining a second interference degree corresponding to the wireless access point according to access point information corresponding to the wireless access point.

[0080] S203: Determine a first interference level corresponding to the channel according to second interference levels corresponding to all wireless access points in the channel.

[0081] With respect to the above-mentioned steps S202 and S203, the second interference degree characterizes the interference degree of the wireless access point to the wireless network of the target device. After obtaining the channel information corresponding to multiple channels in the network environment around the target device, for each channel, the second interference degree corresponding to each channel can be determined according to the access point information corresponding to each wireless access point in the channel, so as to determine the first interference degree corresponding to the channel by using the second interference degree corresponding to all wireless access points in the channel, and then use the determined first interference degree corresponding to each channel to switch the channel of the target device, so as to switch the first channel to the determined channel, so that the target device works on the determined channel.

[0082] In this embodiment, determining the second interference level corresponding to the wireless access point according to the access point information corresponding to the wireless access point in step S202 includes:

[0083] Get the preset signal strength threshold;

[0084] A sum of a preset signal strength threshold and a signal strength of a wireless access point corresponding to the wireless access point is determined to obtain a second interference degree corresponding to the wireless access point.

[0085] The access point information includes the signal strength of the wireless access point. The preset signal strength threshold is the absolute value of the minimum signal strength corresponding to the wireless access point. For example, the signal strength of the wireless access point is usually -1 to -100, so the preset signal strength threshold is 100, and the sum of the preset signal strength threshold and the signal strength of the wireless access point corresponding to the wireless access point is used to obtain the second interference level corresponding to the wireless access point. After obtaining the second interference level corresponding to each wireless access point in the channel, the second interference level corresponding to all wireless access points in the channel can be calculated to obtain the first interference level corresponding to the channel.

[0086] The second interference level corresponding to the wireless access point in the above description can be expressed by the following formula:

[0087] D AP =100+RSSI

[0088] In the above formula, D AP represents the second interference level corresponding to the wireless access point, 100 represents the preset signal strength threshold, and RSSI represents the signal strength of the wireless access point.

[0089] Specifically, determining the first interference level corresponding to the channel according to the second interference levels corresponding to all wireless access points in the channel in step S203 includes:

[0090] Determine a sum value of second interference levels corresponding to all wireless access points in the channel to obtain a second interference level sum value;

[0091] The second interference level and value are determined as the first interference level corresponding to the channel.

[0092] Among them, after obtaining the second interference levels corresponding to all wireless access points in the channel, the sum of the second interference levels corresponding to all wireless access points in the channel can be calculated to determine the determined sum as the first interference level corresponding to the channel, so as to use the first interference level corresponding to the channel to characterize the interference level of the channel to the wireless network of the target device, and then according to the interference level of each channel in the network environment around the target device to the wireless network of the target device, the best channel is selected from all channels in the network environment around the target device, so as to switch the target device to the best channel to work, so as to ensure the performance of the wireless network of the target device.

[0093] The first interference degree mentioned above can be expressed by the following formula:

[0094]

[0095] In the above formula, D1 represents the first interference level, D APirepresents the second interference level corresponding to the i-th wireless access point in the channel, and n represents the number of all wireless access points in the channel.

[0096] S204: Determine a second channel from the multiple channels according to the first interference levels corresponding to the multiple channels.

[0097] In this embodiment, after obtaining the first interference levels corresponding to the multiple channels, the channel corresponding to the minimum first interference level can be determined from the multiple channels according to the multiple first interference levels, and the channel corresponding to the minimum first interference level can be determined as the second channel. Since the channels adjacent to the channel will also affect the calculation of the interference level of the channel to the wireless network of the target device, the step S204 in this embodiment determines the second channel from the multiple channels according to the first interference levels corresponding to the multiple channels, including:

[0098] For each channel, perform the following operations:

[0099] determining at least one third channel corresponding to the channel from the plurality of channels;

[0100] Determine the sum of the first interference levels corresponding to all the second channels to obtain a first interference level sum value;

[0101] Determining a target interference level corresponding to the channel according to the first interference level corresponding to the channel and the first interference level and value;

[0102] A second channel is determined from the multiple channels according to target interference levels corresponding to the multiple channels.

[0103] The third channel is a channel adjacent to the channel. Figure 4 As shown in the figure, there is a 20M wireless access point on channel 6, and channel 5 and channel 7 are adjacent channels of channel 6. Among them, the channels connected to the channel can be obtained by scanning the wireless access point, that is, the access point information corresponding to the wireless access point includes the channel where the wireless access point is located and the channels adjacent to the channel.

[0104] Specifically, after obtaining the first interference degree corresponding to each channel in the network environment around the target device, for each channel in the network around the target device, at least one third channel adjacent to the channel can be determined from multiple channels in the network environment around the target device according to the access point information corresponding to each wireless access point in the channel, so as to sum the first interference degrees corresponding to the determined third channels to obtain the first interference degree sum value, and then comprehensively determine the target interference degree corresponding to the channel according to the first interference degree corresponding to the channel and the first interference degree sum value, so as to use the target interference degree to characterize the interference effect of the channel on the wireless network of the target device, and then use the target interference degrees corresponding to multiple channels in the network environment around the target device to more accurately determine the best second channel from multiple channels, and then switch the target device to the second channel to operate.

[0105] In the above, determining the target interference level corresponding to the channel according to the first interference level corresponding to the channel and the first interference level and value includes:

[0106] Determine the target weight corresponding to the channel;

[0107] Using the target weight to adjust the first interference degree and value to obtain an adjusted first interference degree and value;

[0108] A sum value between the first interference level and the first interference level sum value is determined to obtain a target interference level corresponding to the channel.

[0109] Among them, the target weight characterizes the degree of interference of at least one third channel corresponding to the channel to the channel. The target weights corresponding to different channels can be set according to actual needs, and the specific values ​​of the target weights corresponding to different channels are not limited in this embodiment. When determining the target interference degree, the correspondence between different channels and weights can be pre-set, so that based on the channel, the above correspondence is queried to obtain the target weight corresponding to the channel. In obtaining the target weight, the product between the target weight and the first interference degree and value can be determined, and the product is used as the adjusted first interference degree and value, so as to sum the first interference degree and the first interference degree and value to obtain the final target interference degree corresponding to the channel.

[0110] Specifically, the target interference level corresponding to the channel can be determined by the following formula:

[0111]

[0112] In the above formula, D T represents the target interference level corresponding to the channel, D1 represents the first interference level corresponding to the channel, and D jrepresents the third channel adjacent to the j-th channel, m represents the number of third channels adjacent to the channel, and v represents the target weight corresponding to the channel.

[0113] In the above, determining the second channel from the multiple channels according to the target interference levels corresponding to the multiple channels includes:

[0114] Sorting the target interference levels corresponding to the multiple channels in order from small to large, so as to obtain a target sorting result;

[0115] Determine the channel that ranks first from the target ranking results;

[0116] The channel that is ranked first in the target sorting result is determined as the second channel.

[0117] Among them, in order to determine the channel with the least interference effect on the wireless network of the target device from multiple channels in the network environment around the target device, the target interference degrees corresponding to the multiple channels are sorted in order from small to large, so as to obtain a target sorting result. The target interference degree corresponding to the channel ranked first in the target sorting result is the smallest, and the interference effect of this channel on the wireless network of the target device is the smallest. Therefore, the channel ranked first in the target sorting result is determined as the second channel to be switched by the target device, thereby ensuring the performance of the wireless network of the subsequent target device.

[0118] S205: Switch the target device from the first channel to the second channel to operate.

[0119] In this embodiment, step S205 is consistent with the above-mentioned step S104. For details, please refer to the above-mentioned step S104, and this embodiment will not be described in detail here.

[0120] The present embodiment provides a channel switching method. When a target device is operating on a first channel, the interference degree of each channel to the wireless network of the target device is determined by channel information corresponding to multiple channels in the surrounding environment of the target device, so as to determine the best second channel from the multiple channels according to the determined interference degrees, and then automatically switch the target device to the second channel for operation, thereby avoiding the problems of inaccurate and low efficiency of channel switching when manually switching the second channel, and improving the accuracy and efficiency of channel switching.

[0121] As an example, refer to Figure 4 , let's introduce the whole channel switching process in detail, as follows:

[0122] When the device works on the first channel, each wireless access point in the network environment around the device is scanned to obtain access point information corresponding to each wireless access point;

[0124] For each channel, determining a first interference degree corresponding to the channel according to signal strengths of wireless access points corresponding to each wireless access point in the channel information corresponding to the channel;

[0125] For each channel, determining at least one third channel adjacent to the channel from the plurality of channels;
