[0058] Please refer to the drawings, in which the same component symbols represent the same components. The principle of the present application is illustrated by being implemented in a suitable computing environment. The following description is based on the specific embodiments of the present application illustrated, and should not be regarded as limiting other specific embodiments of the present application not detailed herein.

[0059] Please refer to Figure 1 , Figure 1 which is the first flowchart of the device control method provided by the embodiment of the present application. The device control method can be applied to an electronic device, and the electronic device is a device with a first role, and the first role can be a workstation role or a group client role, that is, the electronic device can be a device with a workstation (STA) role or a group client (GC) role. The process of the device control method can include:

[0060] 101. Determine the initial working channel of the target device with a second role accessed by the electronic device, where the second role is an access point role or a group owner role.

[0061] Wi-Fi is a wireless local area network technology created based on the IEEE 802.11 standard. Wi-Fi technology has become the most widely used wireless network transmission technology at present. Using Wi-Fi technology, mobile terminals such as smart phones and laptops can be connected to an access point (AP), and through the access point, they can be connected to the Internet to use network services. However, in related technologies, the performance of data transmission using Wi-Fi connections is poor. For example, in related technologies, when a smart mobile terminal is connected to an access point, the working channel for their communication generally fixedly uses a bandwidth of 20 MHz or 40 MHz. Among them, if the working channel with a bandwidth of 20 MHz is fixedly used, then the performance of Wi-Fi communication always remains at a relatively low level. If the working channel with a bandwidth of 40 MHz is fixedly used, then when the interference in the environment is strong, the performance of Wi-Fi communication may be worse than that of using the working channel with a bandwidth of 20 MHz.

[0062] There are two roles in ordinary Wi-Fi connection communication: Access Point (hereinafter referred to as AP) and Station (hereinafter referred to as STA). Wi-Fi Display (WFD) is a specification developed by the Wi-Fi Alliance, which enables multimedia devices to establish and maintain a Wi-Fi-based connection and use this connection to promote the presentation and playback of video / audio on the target device. An important technology in Wi-Fi Display is Wi-Fi Direct, that is, Wi-Fi P2P. It supports direct connection and communication between two Wi-Fi devices without an Access Point AP. In the Wi-Fi Direct functional structure, two roles are defined: Group Owner (GO) and Group Client (GC). Among them, the role of the Group Owner GO is similar to that of the Access Point AP in Infrastructure BSS. And the role of the Group Client GC is similar to that of the Station STA in Infrastructure BSS. Before forming a P2P Group (i.e., P2P Network), each terminal is a P2P Device. When P2P negotiation is completed among these P2P Device devices, one and only one P2P Device will play the role of GO, and the other P2P Devices will play the role of GC.

[0063] In the embodiment of the present application, for example, when an electronic device in the STA role or GC role accesses an AP or GO device and needs to determine the bandwidth width of the working channel between them, the electronic device can first obtain the current working channel (i.e., the initial working channel) of the AP or GO device it accesses. For example, the AP or GO device accessed by the electronic device is currently working on Channel 7 in the 2.4 GHz band. Among them, the frequency range of the 2.4 GHz band is 2.400 - 2.4835 GHz. The center frequency of Channel 7 is 2442 MHz, the low-end frequency of the channel is 2431 MHz, and the high-end frequency of the channel is 2453 MHz.

[0064] It should be noted that an AP or GO device will determine a working channel as its initial working channel after startup, even if no STA or GC device has accessed the AP or GO device yet.

[0065] It should also be noted that when the electronic device is a device in the STA role, the role of the target device accessed by the electronic device is correspondingly the AP role. And when the electronic device is a device in the GC role, the role of the target device accessed by the electronic device is correspondingly the GO role.

[0066] 102. Determine a channel to be detected according to the initial working channel, where the channel to be detected is within the preset bandwidth range corresponding to the initial working channel.

[0067] For example, after determining the initial working channel of the target device accessed by the electronic device, the electronic device can determine the channel to be detected according to the initial working channel, where the channel to be detected is within the preset bandwidth range corresponding to the initial working channel.

[0068] Channels in the 2.4 GHz band can use a bandwidth of 20 MHz or 40 MHz. Among them, the 40 MHz bandwidth is formed by bundling two 20 MHz bandwidth channels together to form a 40 MHz bandwidth.

[0069] For example, the preset bandwidth is 40 MHz. Then, in process 102, the electronic device can determine the channel to be detected according to the initial working channel of the target device it accesses, and the channel to be detected is within the coverage range of the 40 MHz bandwidth corresponding to the initial working channel.

[0070] 103. Obtain the sum of the numbers of devices with a second role operating on the initial working channel and the channel to be detected in the environment.

[0071] For example, the electronic device can also obtain the sum of the numbers of devices with the AP and GO roles operating on the above initial working channel and the channel to be detected in the environment it is in.

[0072] For example, the current working channel is channel 7, and the channels to be detected include channels 2, 3, 4, 5, 6, 8, and 9. Then, in process 103, the electronic device can obtain the sum of the numbers of AP and GO devices operating on channels 2, 3, 4, 5, 6, 7, 8, and 9 in the environment.

[0073] 104. Obtain the channel idle parameters of the initial working channel and the channel to be detected.

[0074] For example, the electronic device can also obtain the channel idle parameters of each of the above initial working channel and the channel to be detected. Among them, the channel idle parameter can represent the idle degree of a channel.

[0075] 105. Obtain the received signal strength of the target device accessed by the electronic device.

[0076] For example, the electronic device can also obtain the received signal strength (Received Signal Strength Indication, RSSI) of the target device it accesses.

[0077] After obtaining the sum of the numbers of AP and GO devices operating on the above-mentioned initial working channel and the channel to be detected in the environment, the channel idle parameters of the above-mentioned initial working channel and the channel to be detected, and the received signal strength RSSI of the target device accessed by the electronic device, the electronic device can detect whether the sum of the numbers is less than or equal to a preset first threshold, whether the channel idle parameter meets the first condition, and whether the RSSI of the target device accessed by the electronic device is greater than or equal to a preset second threshold.

[0078] If it is detected that the sum of the numbers is less than or equal to a preset first threshold, the channel idle parameter meets the first condition, and the RSSI of the target device accessed by the electronic device is greater than or equal to a preset second threshold, then it can enter 106. Otherwise, the electronic device can perform other operations.

[0079] 106. If it is detected that the sum of the numbers is less than or equal to a preset first threshold, the channel idle parameter meets the first condition, and the received signal strength of the target device is greater than or equal to a preset second threshold, then determine the target channel, and perform Wi-Fi communication between the electronic device and the target device through the target channel, where the bandwidth of the target channel is greater than the bandwidth of the initial working channel.

[0080] For example, if the electronic device detects that the sum of the numbers is less than or equal to a preset first threshold, the channel idle parameter meets the first condition, and the RSSI of the target device accessed by the electronic device is greater than or equal to a preset second threshold, then it can be considered that the interference in the environment where the electronic device is currently located is small. In this case, the electronic device can determine the target channel and perform Wi-Fi communication between the electronic device and the target device through the target channel. Among them, the bandwidth of the target channel can be greater than the bandwidth of the initial working channel. For example, the bandwidth of the initial working channel is 20MHz, and the bandwidth of the target channel is 40MHz. Then, when it is detected that the sum of the numbers is less than or equal to a preset first threshold, the channel idle parameter meets the first condition, and the RSSI of the target device accessed by the electronic device is greater than or equal to a preset second threshold, the electronic device can use the target channel with a bandwidth of 40MHz to perform Wi-Fi communication between the electronic device and the target device it accesses. For example, the electronic device can use Channel 7 as the primary channel and Channel 6 or Channel 8 as the secondary channel to form a target channel with a bandwidth of 40MHz, and perform Wi-Fi communication with the target device it accesses based on the target channel with a bandwidth of 40MHz. Otherwise, the electronic device can use Channel 7 with a bandwidth of 20MHz to perform Wi-Fi communication between the electronic device and the target device it accesses.

[0081] It can be understood that in the embodiments of the present application, when the working environment of the electronic device meets certain conditions (that is, the sum of the above quantities is less than or equal to a preset first threshold, the channel idle parameter meets the first condition, and the RSSI of the target device accessed by the electronic device is greater than or equal to a preset second threshold), the electronic device can use a target channel with a larger bandwidth than the initial working channel for Wi-Fi communication between the electronic device and the target device it accesses. That is, in the embodiments of the present application, the electronic device can use a channel with a larger bandwidth for Wi-Fi communication in an environment with less interference, thereby improving the performance of data transmission using Wi-Fi connection.

[0082] Please refer to Figure 2 , Figure 2 which is the second flowchart of the device control method provided by the embodiments of the present application. The device control method can be applied to an electronic device, and the electronic device is a device with a first role, and the first role can be a workstation role or a group client role, that is, the electronic device can be a device with a workstation (STA) role or a group client (GC) role. The process of the device control method can include:

[0083] 201. The electronic device determines the initial working channel of the target device with a second role it accesses, and the second role is an access point role or a group owner role.

[0084] For example, when an electronic device with an STA role or a GC role accesses an AP or GO device and needs to determine what bandwidth width to use for the working channel between them, the electronic device can first obtain the current working channel (i.e., the initial working channel) of the target device it accesses. For example, the target device accessed by the electronic device is currently working on channel 7 in the 2.4 GHz band, that is, channel 7 is the initial working channel.

[0085] It should be noted that when the electronic device is a device with an STA role, the role of the target device accessed by the electronic device is correspondingly an AP role. And when the electronic device is a device with a GC role, the role of the target device accessed by the electronic device is correspondingly a GO role.

[0086] 202. According to the initial working channel, the electronic device determines the channel to be detected, and the channel to be detected is within the preset bandwidth range corresponding to the initial working channel.

[0087] For example, after determining the initial working channel of the target device accessed by the electronic device, the electronic device can determine the channel to be detected according to the initial working channel, where the channel to be detected is within the preset bandwidth range corresponding to the initial working channel. In one implementation, the preset bandwidth can be a bandwidth greater than 20 MHz.

[0088] The channels in the 2.4GHz band can use a bandwidth of 20MHz or 40MHz. Among them, the 40MHz bandwidth is formed by bundling two 20MHz bandwidth channels together to form a 40MHz bandwidth.

[0089] For example, the preset bandwidth is 40MHz. Then, in the 202 process, the electronic device can determine the channel to be detected according to the initial working channel of the target device it accesses - the 7th channel. The channel to be detected is within the coverage range of the 40MHz bandwidth corresponding to the 7th channel.

[0090] In one implementation, the electronic device can determine the channel to be detected according to the initial working channel in the following way:

[0091] The electronic device obtains the way in which the target device it accesses uses the preset bandwidth on the initial working channel, and this way is one of the plus channel superposition and minus channel superposition;

[0092] According to the way in which the target device uses the preset bandwidth on the initial working channel and the initial working channel, the electronic device determines the channel to be detected.

[0093] It should be noted that taking the preset bandwidth as 40MHz and the initial working channel of the target device accessed by the electronic device as the 7th channel in the 2.4GHz band as an example. The electronic device can first obtain the way in which the target device it accesses uses the 40MHz bandwidth on the 7th channel. Among them, this way includes plus channel superposition and minus channel superposition.

[0094] It should also be noted that the 40MHz bandwidth is formed by bundling two adjacent 20MHz bandwidth channels together to form a 40MHz channel, one is the main channel and the other is the auxiliary channel. The main channel sends beacon messages and some data messages, and the auxiliary channel sends other messages. If the center frequency of the auxiliary channel is higher than that of the main channel when bundling two adjacent 20MHz channels, it is plus. If the center frequency of the auxiliary channel is lower than that of the main channel when bundling two adjacent 20MHz channels, it is minus. Here, plus and minus are both relative to the main channel. For example, the current channel is 7. To configure a 40MHz bandwidth with plus, another channel needs to be superimposed, that is, the 40MHz bandwidth composed of the 7th channel and the 8th channel. Minus means that the channel superposition is downward when superimposing channels. For example, the 7th channel and the 6th channel form a new 40MHz bandwidth channel.

[0095] In this embodiment, the electronic device can obtain the beacon data packet of the target device it accesses, and obtain the way in which the accessed target device uses a 40 MHz bandwidth on the initial working channel from the beacon data packet.

[0096] After determining the way in which the target device accessed by the electronic device uses a 40 MHz bandwidth on the current working channel, the electronic device can determine the channel to be detected in the following way:

[0097] If the way in which the target device accessed by the electronic device uses a 40 MHz bandwidth on the initial working channel is the downlink channel aggregation, the electronic device determines 8 consecutive channels including the initial working channel as the first object channels; the electronic device determines the other channels in the first object channels except the initial working channel as the channels to be detected, where the number of channels in the channels to be detected that are lower than the initial working channel is greater than the number of channels that are higher than the initial working channel.

[0098] Alternatively, if the way in which the target device accessed by the electronic device uses a 40 MHz bandwidth on the initial working channel is the uplink channel aggregation, the electronic device determines 8 consecutive channels including the initial working channel as the second object channels; the electronic device determines the other channels in the second object channels except the initial working channel as the channels to be detected, where the number of channels in the channels to be detected that are lower than the initial working channel is less than the number of channels that are higher than the initial working channel.

[0099] For example, if the initial working channel is Channel 7 and the electronic device uses the method of stacking channels downward (minus) to construct a 40 MHz bandwidth channel, the electronic device can determine 8 consecutive channels including Channel 7 as the first object channels, and then determine the other channels except Channel 7 among these 8 channels as the channels to be detected, where the number of channels lower than Channel 7 among the channels to be detected is greater than the number of channels higher than Channel 7. For example, the 8 consecutive channels including Channel 7 are Channels 2, 3, 4, 5, 6, 7, 8, and 9. Then, the electronic device can determine Channels 2, 3, 4, 5, 6, 8, and 9 as the channels to be detected, where the number of channels lower than Channel 7 is 5 (Channels 2, 3, 4, 5, 6), and the number of channels higher than Channel 7 is 2 (Channels 8, 9). Another example, the 8 consecutive channels including Channel 7 are Channels 3, 4, 5, 6, 7, 8, 9, and 10. Then, the electronic device can determine Channels 3, 4, 5, 6, 8, 9, and 10 as the channels to be detected, where the number of channels lower than Channel 7 is 4 (Channels 3, 4, 5, 6), and the number of channels higher than Channel 7 is 3 (Channels 8, 9, 10).

[0100] For example, if the initial working channel is Channel 7 and the electronic device uses the method of stacking channels upward (plus) to construct a 40 MHz bandwidth channel, the electronic device can determine 8 consecutive channels including Channel 7 as the second object channels, and then determine the other channels except Channel 7 among these 8 channels as the channels to be detected, where the number of channels lower than Channel 7 among the channels to be detected is less than the number of channels higher than Channel 7. For example, the 8 consecutive channels including Channel 7 are Channels 4, 5, 6, 7, 8, 9, 10, and 11. Then, the electronic device can determine Channels 4, 5, 6, 8, 9, 10, and 11 as the channels to be detected, where the number of channels lower than Channel 7 is 3 (Channels 4, 5, 6), and the number of channels higher than Channel 7 is 4 (Channels 8, 9, 10, 11). Another example, the 8 consecutive channels including Channel 7 are Channels 5, 6, 7, 8, 9, 10, 11, and 12. Then, the electronic device can determine Channels 5, 6, 8, 9, 10, 11, and 12 as the channels to be detected, where the number of channels lower than Channel 7 is 2 (Channels 5, 6), and the number of channels higher than Channel 7 is 5 (Channels 8, 9, 10, 11, 12).

[0101] 203. The electronic device obtains the sum of the numbers of devices with a second role operating on the initial working channel and the to-be-detected channels in the environment.

[0102] For example, the electronic device can also obtain the sum of the numbers of devices with a second role operating on the above-mentioned initial working channel and the to-be-detected channels in the environment where it is located, that is, the electronic device can obtain the numbers of AP and GO devices operating on the above-mentioned initial working channel and the to-be-detected channels in the environment where it is located.

[0103] For example, the initial working channel is channel 7, and the to-be-detected channels include channels 2, 3, 4, 5, 6, 8, and 9. Then, in the 203 process, the electronic device can obtain the sum of the numbers of AP and GO devices operating on channels 2, 3, 4, 5, 6, 7, 8, and 9 in the environment.

[0104] 204. The electronic device scans the initial working channel and the to-be-detected channels, and obtains the channel idle time and the channel scan time of each channel during the scanning.

[0105] 205. According to the channel idle time and the channel scan time of each channel, the electronic device calculates the channel idle ratio of each channel, where the channel idle ratio is the ratio of the channel idle time to the channel scan time.

[0106] 206. The electronic device calculates the average channel idle ratio of the initial working channel and the to-be-detected channels, and uses the average channel idle ratio and the channel idle ratios of each channel as channel idle parameters.

[0107] For example, 204, 205, and 206 may include:

[0108] After determining the to-be-detected channels, the electronic device can scan the initial working channel of the target device it accesses and the to-be-detected channels. When scanning the initial working channel and the to-be-detected channels, the electronic device can obtain the channel idle time (channel idle slot time) and the channel scan time (scan time) of each of these channels.

[0109] It should be noted that in the related art, the channel idle time (channel idle slot time) and the scan time are not returned during channel scanning. In the embodiments of the present application, the information of the channel idle time (channel idle slot time) and the scan time will be additionally returned in the scan result of the channel scanning.

[0110] For example, please refer to Figure 3 , Figure 3Schematic diagram of Wi-Fi channel scanning where the electronic device provided by the embodiment of this application additionally returns the channel number, channel idle slot time, and scan time during channel scanning. Among them, Wi-Fi Driver is the Wi-Fi driver module, Wi-Fi Firmware is the Wi-Fi firmware, Wi-Fi Hardware is the Wi-Fi hardware, Packet Tx represents sending data packets, and Packet Rx represents receiving data packets. That is, when scanning each channel, the electronic device can additionally obtain and return the channel idle slot time and scan time. In this way, the electronic device can obtain the channel idle time and scan time of each channel during channel scanning.

[0111] After obtaining the channel idle time and scan time of each channel, the electronic device can calculate the channel idle slot ratio corresponding to each channel, where the channel idle slot ratio is the ratio of the channel idle time to the scan time. For example, if the channel idle time of Channel 2 is 30 ms and the scan time is 50 ms, then the channel idle slot ratio of Channel 2 is 30 ms / 50 ms = 0.6.

[0112] Moreover, the electronic device can also calculate the average channel idle slot ratio of the above-mentioned initial working channel and the channels to be detected. That is, the average channel idle slot ratio is the average value of the sum of the channel idle slot ratios of the above-mentioned initial working channel and the channels to be detected.

[0113] In this embodiment, the electronic device can use the above-mentioned average channel idle slot ratio and the channel idle slot ratios of each channel in the above-mentioned initial working channel and the channels to be detected as channel idle parameters.

[0114] 207. The electronic device obtains the received signal strength of the target device it is connected to.

[0115] For example, the electronic device can also obtain the received signal strength RSSI of the target device it is connected to.

[0116] After obtaining the sum of the numbers of AP and GO devices operating on the above-mentioned initial working channel and the channel to be detected in the environment, the channel idle parameters of the above-mentioned initial working channel and the channel to be detected, and the received signal strength RSSI of the target device accessed by the electronic device, the electronic device can detect whether the sum of the numbers is less than or equal to a preset first threshold, whether the above-mentioned channel idle parameters meet a preset first condition, and whether the RSSI of the target device accessed by the electronic device is greater than or equal to a preset second threshold. Among them, the above-mentioned first condition is that the channel idle ratio of each channel in the above-mentioned initial working channel and the channel to be detected is greater than or equal to a preset third threshold, and the average channel idle ratio is greater than or equal to a preset fourth threshold.

[0117] If it is detected that the sum of the numbers is less than or equal to the first threshold, the above-mentioned channel idle parameters meet the preset first condition, and the RSSI of the target device accessed by the electronic device is greater than or equal to the preset second threshold, then it is possible to enter 208.

[0118] 208. If the sum of the numbers is less than or equal to the preset first threshold, the channel idle parameters meet the first condition, and the received signal strength of the target device is greater than or equal to the preset second threshold, the electronic device determines the target channel and performs Wi-Fi communication between the electronic device and the target device through the target channel. The bandwidth of the target channel is greater than the bandwidth of the initial working channel. Among them, when the channel idle ratio of each channel in the above-mentioned initial working channel and the channel to be detected is greater than or equal to the preset third threshold, and the average channel idle ratio is greater than or equal to the preset fourth threshold, it is determined that the channel idle parameters meet the first condition.

[0119] For example, if the sum of the numbers is less than or equal to the preset first threshold, the channel idle parameters meet the first condition, and the received signal strength of the target device accessed by the electronic device is greater than or equal to the preset second threshold, it can be considered that the interference in the environment where the electronic device is currently located is small. In this case, the electronic device can determine the target channel and perform Wi-Fi communication between the electronic device and the target device through the target channel. Among them, the bandwidth of the target channel can be greater than the bandwidth of the initial working channel. For example, the bandwidth of the target channel is 40MHz bandwidth. Among them, the channel idle parameters meeting the first condition can indicate that the relevant channels are relatively idle. For example, the electronic device can use Channel 7 as the main channel and Channel 6 as the secondary channel to construct a target channel with a 40MHz bandwidth for performing Wi-Fi communication between the electronic device and the target device it accesses.

[0120] Otherwise, the electronic device can continue to use the 20MHz bandwidth of Channel 7 to perform Wi-Fi communication between the electronic device and the AP or GO device it accesses.

[0121] It can be understood that in the embodiments of the present application, when the sum of the number of AP and GO devices operating on the above-mentioned initial working channel and the to-be-detected channel in the environment is less than a preset first threshold, and the channel idle ratio of each channel in the above-mentioned initial working channel and the to-be-detected channel is greater than or equal to a preset third threshold, and the average channel idle ratio is greater than or equal to a preset fourth threshold, and the RSSI of the target device accessed by the electronic device is greater than or equal to a preset second threshold, it can be considered that the interference in the environment where the electronic device is located is small. In the case of small interference in the environment, the electronic device can use a channel with a 40MHz bandwidth for Wi-Fi communication. In the case of large interference in the environment, the electronic device can use a channel with a 20MHz bandwidth for Wi-Fi communication. Since the Wi-Fi communication transceiver performance of the 40MHz bandwidth channel is better than that of the 20MHz bandwidth channel, in this embodiment, when the environmental interference is small, the electronic device using a channel with a 40MHz bandwidth for Wi-Fi communication can have better communication performance.

[0122] In another implementation, the medium ready count can also be used as the channel idle parameter. The value of the parameter medium ready count represents the number of Wi-Fi packets detected by the Wi-Fi physical layer. When the number is relatively small, for example, the value of medium ready count is less than 100 within 500ms, then it can be considered that the interference on the corresponding channel is small.

[0123] For example, when it is detected that the sum of the number of access points and group owner devices operating on the initial working channel and the to-be-detected channel in the environment is less than or equal to a preset first threshold, and the value of the above-mentioned medium ready count is less than a preset value, and the received signal strength of the target device accessed by the electronic device is greater than or equal to a preset second threshold, it can be considered that the current environmental interference is small. In this case, the electronic device can use a target channel with a preset bandwidth (such as 40MHz bandwidth) to perform Wi-Fi communication with the target device it accesses.

[0124] Please refer to Figure 4 , Figure 4 FIG. is the third flowchart of the device control method provided by the embodiments of the present application. The device control method can be applied to an electronic device, and the electronic device can be a device with a second role, and the second role is an access point (AP) role or a group owner (GO) role. The process of the device control method can include:

[0125] 301. Determine the initial working channel of the electronic device.

[0126] In the embodiments of the present application, for example, when a device in the STA role or GC role accesses an electronic device in the AP role or GO role and needs to determine what width of bandwidth to use for the working channel between them, the electronic device can first obtain its current working channel (i.e., the initial working channel). For example, the electronic device is currently working on Channel 7 in the 2.4 GHz band.

[0127] 302. Determine a channel to be detected according to the initial working channel, where the channel to be detected is within the preset bandwidth range corresponding to the initial working channel.

[0128] For example, after determining the initial working channel of the electronic device, the electronic device can determine the channel to be detected according to the initial working channel, where the channel to be detected is within the preset bandwidth range corresponding to the initial working channel.

[0129] For example, the preset bandwidth is 40 MHz. Then, in step 302, the electronic device can determine the channel to be detected according to its initial working channel, and the channel to be detected is within the coverage range of the 40 MHz bandwidth corresponding to the initial working channel. How to determine the channel to be detected according to the initial working channel has been described in detail above and will not be elaborated here.

[0130] 303. Obtain the sum of the numbers of devices with the second role working on the initial working channel and the channel to be detected in the environment.

[0131] For example, the electronic device can also obtain the numbers of AP and GO devices working on the above initial working channel and the channel to be detected in its environment.

[0132] For example, the initial working channel is Channel 7, and the channels to be detected include Channels 2, 3, 4, 5, 6, 8, and 9. Then, in step 303, the electronic device can obtain the sum of the numbers of AP and GO devices working on Channels 2, 3, 4, 5, 6, 7, 8, and 9 in the environment.

[0133] 304. Obtain the channel idle parameters of the initial working channel and the channel to be detected.

[0134] For example, the electronic device can also obtain the channel idle parameters of each of the above initial working channel and the channel to be detected. Among them, the channel idle parameter can represent the idle degree of a channel.

[0135] 305. Obtain the sum of the received signal strengths of other devices with the second role working on the initial working channel and the channel to be detected in the environment.

[0136] For example, the electronic device can also obtain the sum of the RSSIs of other AP and GO devices working on the initial working channel and the channel to be detected in the environment.

[0137] After that, the electronic device can detect whether the sum of the above - mentioned quantities is less than or equal to a preset first threshold, whether the channel idle parameter meets the first condition, and whether the sum of the received signal strengths of other devices with the second role is less than or equal to a preset fifth threshold. If so, it can enter the process of 306. Otherwise, the electronic device can perform other operations.

[0138] 306. If it is detected that the sum of the above - mentioned quantities is less than or equal to a preset first threshold, the channel idle parameter meets the first condition, and the sum of the received signal strengths of other devices with the second role is less than or equal to a preset fifth threshold, then determine a target channel, and perform Wi - Fi communication between the electronic device and the device with the first role connected thereto through the target channel. The bandwidth of the target channel is greater than the bandwidth of the initial working channel, and the first role is a workstation role or a group client role.

[0139] For example, if the electronic device detects that the sum of the above - mentioned quantities is less than or equal to a preset first threshold, the channel idle parameter meets the first condition, and the sum of the RSSIs of other access points and group owner devices operating on the initial working channel and the channels to be detected is less than or equal to a preset fifth threshold, then it can be considered that the interference in the environment where the electronic device is currently located is small. In this case, the electronic device can determine a target channel and perform Wi - Fi communication between the electronic device and the device with the first role connected thereto through the target channel. The bandwidth of the target channel is greater than the bandwidth of the initial working channel, and the first role is a workstation role or a group client role. For example, the electronic device can use Channel 7 as the primary channel and Channel 6 or Channel 8 as the secondary channel to form a target channel with a 40MHz bandwidth, and perform Wi - Fi communication based on the 40MHz - bandwidth target channel and its corresponding STA or GC device. Otherwise, the electronic device can still use Channel 7 with a 20MHz bandwidth to perform Wi - Fi communication between the electronic device and its corresponding STA or GC device.

[0140] It can be understood that in the embodiments of the present application, the electronic device can use a channel with a larger bandwidth for Wi - Fi communication in an environment with less interference, thereby improving the performance of data transmission using Wi - Fi connections.

[0141] In one implementation, the channel idle parameter in 306 can be the channel idle ratio of each channel in the initial working channel and the channels to be detected of the electronic device. Then, the above - mentioned channel idle parameter meeting the preset first condition can be that the channel idle ratio of each channel in the initial working channel and the channels to be detected of the electronic device is greater than or equal to a preset third threshold.

[0142] Alternatively, the channel idle parameter in 306 may be the channel idle ratio of each channel in the initial working channel and the channels to be detected of the electronic device, as well as the average channel idle ratio of these channels. Then, the above channel idle parameter satisfying the preset first condition may be that the channel idle ratio of each channel in the initial working channel and the channels to be detected of the electronic device is greater than or equal to a preset third threshold, and the average channel idle ratio of these channels is greater than or equal to a preset fourth threshold.

[0143] Please refer to Figures 5 to 6 , Figures 5 to 6 which is a schematic diagram of the scenario of the device control method provided by the embodiments of the present application.

[0144] For example, there are electronic device D1 and electronic device D2, and the user wants to wirelessly screen mirror the audio and video files on electronic device D2 to electronic device D1 for playing. The user can turn on the Wi-Fi functions of electronic devices D1 and D2, thereby establishing a Wi-Fi P2P connection between electronic devices D1 and D2, as Figure 5 shown.

[0145] Through negotiation, electronic device D1 is determined to be the role of the group owner GO, and electronic device D2 is determined to be the role of the group client GC. Among them, the working channel of GO device D1 is, for example, channel 7 in the 2.4 GHz band. Before establishing a formal connection, GC device D2 can first obtain the current working channel of GO device D1, that is, channel 7. Among them, GO device D1 supports 20 MHz bandwidth and 40 MHz bandwidth.

[0146] After that, GC device D2 can determine the channels to be detected according to the current working channel 7 of GO device D1. For example, the way GO device D1 uses 40 MHz bandwidth on channel 7 is the downward stacked channel minus. Then, the channels to be detected may be, for example, channels 2, 3, 4, 5, 6, 8, and 9.

[0147] After that, GC device D2 can scan each channel from channel 2 to channel 9 to obtain the sum of the number of APs and GO devices working on channels 2 to 9 in the surrounding environment.

[0148] Moreover, when scanning each channel from channel 2 to channel 9, GC device D2 can additionally obtain the channel idle time (channel idle slot time) and the channel scan time (scan time) of each channel. According to the channel idle time and the channel scan time of each channel, GC device D2 can calculate the channel idle ratio of each channel, where the channel idle ratio is the ratio of the channel idle time to the channel scan time. And after calculating the channel idle ratio of each channel, GC device D2 can also calculate the average channel idle ratio.

[0149] After that, the GC device D2 can also obtain the received signal strength indication (RSSI) of the GO device D1 to which it is connected.

[0150] After obtaining the above information, the GC device D2 can detect whether the sum of the number of APs and GO devices operating on channels 2 to 9 in the surrounding environment is less than or equal to a preset first threshold (for example, the preset first threshold is 7 or 8, etc.), and detect whether the channel idle ratio of each channel in channels 2 to 9 is greater than or equal to a preset third threshold (for example, the preset third threshold is 10% or 20%, etc.) and whether the average channel idle ratio of each channel is greater than or equal to a preset fourth threshold (for example, the preset fourth threshold is 15% or 25%, etc.), and detect whether the received signal strength RSSI of the GO device D1 is greater than or equal to a preset second threshold (for example, the preset second threshold is -75 dBm or -60 dBm, etc.).

[0151] For example, in this embodiment, the detection results of the above four conditions are all yes. For example, the GC device D2 detects that the number of APs and GO devices operating on channels 2 to 9 in the surrounding environment is 5, which is less than the preset first threshold of 7, and detects that the channel idle ratio of each channel in channels 2 to 9 is greater than the preset third threshold of 10%, and the average channel idle ratio of each channel is 30%, which is greater than the preset fourth threshold of 15%, and detects that the received signal strength RSSI of the GO device D1 is -50 dBm, which is greater than the preset second threshold of -75 dBm. In this case, the GC device D2 can determine a channel that can use a 40 MHz bandwidth to perform Wi-Fi communication with the GO device D1. For example, devices D1 and D2 can use channel 7 as the primary channel and channel 6 as the secondary channel to form a 40 MHz bandwidth channel and use this 40 MHz bandwidth channel to perform Wi-Fi communication, as Figure 6 shown.

[0211] Then, when the processor 603 executes that the channel idle parameter satisfies the first condition, it may execute: when the channel idle ratio of each channel in the initial working channel and the channels to be detected is greater than or equal to a preset third threshold, determine that the channel idle parameter satisfies the first condition.
