Detailed Description

Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.

Referring to fig. 1, fig. 1 is a first flowchart illustrating an apparatus control method according to an embodiment of the present disclosure. The device control method may be applied to an electronic device, which is a device having a first role, which may be a workstation role or a group client role, that is, the electronic device may be a device having a workstation (STA) role or a Group Client (GC) role. The flow of the device control method may include:

101. an initial working channel of a target device with a second role accessed by the electronic device is determined, wherein the second role is an access point role or a group owner role.

Wi-Fi is a wireless local area network technology that is built into the IEEE 802.11 standard. Wi-Fi technology has become one of the most widely used wireless network transmission technologies at present. With Wi-Fi technology, a mobile terminal such as a smart phone, a notebook computer, etc. can connect to an Access Point (AP) and connect to the internet through the Access Point, thereby using a web service. However, in the related art, the performance of data transmission using a Wi-Fi connection is poor. For example, in the related art, when the smart mobile terminal is connected to the access point, an operating channel for communication therebetween generally fixedly uses a bandwidth of 20MHz or a bandwidth of 40 MHz. Wherein, if the operating channel with 20MHz bandwidth is used fixedly, the performance of WiFi communication is always maintained at a relatively low level. If the operating channel with the bandwidth of 40MHz is fixedly used, when the interference in the environment is strong, the performance of WiFi communication may be inferior to that of the operating channel with the bandwidth of 20 MHz.

Two roles are involved in normal Wi-Fi connection communication: an Access Point (AP) and a Station (STA). Wi-Fi Display (WFD) is a specification developed by Wi-Fi Alliance that enables a Wi-Fi based connection to be established and maintained between multimedia devices and utilized to facilitate the presentation and playback of video/audio at a target device. An important technology in Wi-Fi Display is Wi-Fi Direct, i.e., Wi-Fi P2P. It supports two Wi-Fi devices to connect and communicate directly without accessing the access point AP. In the Wi-Fi Direct function structure, two roles of a Group Owner (GO) and a Group Client (GC) are defined. Where the group owner GO acts like an access point AP in an Infrastructure BSS. And the group client GC functions like the station STA in the Infrastructure BSS. Before the P2P Group (i.e., P2P Network) is formed, the terminals are P2P devices one by one. When P2P negotiation is completed between these P2P Device devices, one and only one P2P Device will play the GO role, and the other P2P devices will play the GC role.

In this embodiment of the application, for example, when an electronic device in an STA role or a GC role accesses an AP or a GO device and needs to determine what bandwidth is used for an operating channel therebetween, the electronic device may first acquire a current operating channel (i.e., an initial operating channel) of the AP or GO device to which the electronic device is accessed. For example, the AP or GO device accessed by the electronic device currently operates on channel number 7 in the 2.4GHz band. Wherein, the frequency range of the 2.4GHz frequency band is 2.400-2.4835 GHz. Channel No. 7 has a center frequency of 2442MHz, a low end frequency of 2431MHz, and a high end frequency of 2453 MHz.

It should be noted that after the AP or GO device is started, an operating channel is determined as its initial operating channel, even though no STA or GC device has access to the AP or GO device.

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 with a GC role, the role of the target device accessed by the electronic device is correspondingly the GO role.

102. And determining a channel to be detected according to the initial working channel, wherein the channel to be detected is located in a preset bandwidth range corresponding to the initial working channel.

For example, after determining an initial working channel of a target device to which the electronic device is connected, the electronic device may determine a channel to be detected according to the initial working channel, where the channel to be detected is located within a preset bandwidth range corresponding to the initial working channel.

The channel of the 2.4GHz band may use a bandwidth of 20MHz or a bandwidth of 40 MHz. Where the 40MHz bandwidth is a 40MHz bandwidth formed by bundling two 20MHz bandwidth channels.

For example, the preset bandwidth is 40 MHz. Then, the electronic device in the process 102 may determine, according to an initial working channel of the target device to which the electronic device is connected, a channel to be detected, where the channel to be detected is located in a coverage range of a 40MHz bandwidth corresponding to the initial working channel.

103. And acquiring the sum of the number of the devices with the second role working on the initial working channel and the channel to be detected in the environment.

For example, the electronic device may further obtain a sum of the number of devices having the AP and GO roles that operate on the initial operating channel and the channel to be detected in the environment where the electronic device is located.

For example, the current working channel is channel number 7, and the channels to be detected include channel numbers 2, 3, 4, 5, 6, 8, and 9. Then, in flow 103, the electronic device may obtain the sum of the number of AP and GO devices operating on channels No. 2, No. 3, No. 4, No. 5, No. 6, No. 7, No. 8, No. 9 in the environment.

104. And acquiring channel idle parameters of the initial working channel and the channel to be detected.

For example, the electronic device may further obtain channel idle parameters of each of the initial operating channel and the channel to be detected. Wherein the channel idle parameter may indicate an idle degree of a channel.

105. And acquiring the received signal strength of the target equipment accessed by the electronic equipment.

For example, the electronic device may further obtain a Received Signal Strength (RSSI) of a target device connected to the electronic device.

After acquiring the sum of the numbers of the APs and the GO devices operating on the initial operating channel and the channel to be detected in the environment, the channel idle parameters of the initial operating channel and the channel to be detected, and the RSSI of the target device accessed by the electronic device, the electronic device may detect whether the sum of the numbers is less than or equal to a preset first threshold, whether the channel idle parameters satisfy a 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.

If the sum of the above quantities is detected to be 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 the process may be entered into step 106. Otherwise, the electronic device may perform other operations.

106. If the sum of the number is detected to be smaller than or equal to a preset first threshold value, the channel idle parameter meets a first condition, and the received signal strength of the target device is larger than or equal to a preset second threshold value, determining a target channel, and performing Wi-Fi communication between the electronic device and the target device through the target channel, wherein the bandwidth of the target channel is larger than that of the initial working channel.

For example, when the electronic device detects that the sum of the number 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, it may be considered that the interference in the environment where the electronic device is currently located is small. In this case, the electronic device may determine a target channel and perform Wi-Fi communication between the electronic device and the target device over the target channel. Wherein the bandwidth of the target channel may be greater than the bandwidth of the initial operating channel. For example, the bandwidth of the initial operating channel is 20MHz and the bandwidth of the target channel is 40 MHz. Then, when it is detected that the sum of the above 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 may use the target channel with the bandwidth of 40MHz to perform Wi-Fi communication between the electronic device and the target device accessed by the electronic device. For example, the electronic device may configure a target channel with a bandwidth of 40MHz by using the channel No. 7 as a primary channel and the channel No. 6 or the channel No. 8 as a secondary channel, and perform Wi-Fi communication with a target device accessed by the target channel with the bandwidth of 40 MHz. Otherwise, the electronic device may use channel number 7 with 20MHz bandwidth for Wi-Fi communication between the electronic device and a target device accessed by the electronic device.

It can be understood that, in this embodiment of the present application, when an operating environment of the electronic device satisfies a certain condition (that is, a sum of the above number is less than or equal to a preset first threshold, a channel idle parameter satisfies the first condition, and an RSSI of a target device accessed by the electronic device is greater than or equal to a preset second threshold), the electronic device may perform Wi-Fi communication between the electronic device and the target device accessed by the electronic device by using a target channel having a bandwidth greater than that of an initial operating channel. That is, in the embodiment of the present application, the electronic device may use the channel with the larger bandwidth to perform Wi-Fi communication in the environment with less interference, so as to improve the performance of data transmission by using the Wi-Fi connection.

Referring to fig. 2, fig. 2 is a second flowchart illustrating an apparatus control method according to an embodiment of the present disclosure. The device control method may be applied to an electronic device, which is a device having a first role, which may be a workstation role or a group client role, that is, the electronic device may be a device having a workstation (STA) role or a Group Client (GC) role. The flow of the device control method may include:

201. the electronic device determines an initial operating channel of a target device it accesses having a second role, the second role being an access point role or a group owner role.

For example, when an electronic device in an STA role or a GC role accesses an AP device or a GO device and needs to determine what bandwidth is used for an operating channel therebetween, the electronic device may first acquire a current operating channel (i.e., an initial operating channel) of a target device to which the electronic device is accessed. For example, the target device accessed by the electronic device currently operates in channel No. 7 of the 2.4GHz band, that is, channel No. 7 is an initial operating channel.

It should 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 with a GC role, the role of the target device accessed by the electronic device is correspondingly the GO role.

202. According to the initial working channel, the electronic equipment determines a channel to be detected, wherein the channel to be detected is located in a preset bandwidth range corresponding to the initial working channel.

For example, after determining an initial working channel of a target device to which the electronic device is connected, the electronic device may determine a channel to be detected according to the initial working channel, where the channel to be detected is located within a preset bandwidth range corresponding to the initial working channel. In one embodiment, the predetermined bandwidth may be a bandwidth having a width greater than 20 MHz.

For example, the preset bandwidth is 40 MHz. Then, in the process 202, the electronic device may determine, according to the initial working channel — the channel 7 of the target device to which the electronic device is connected, a channel to be detected, where the channel to be detected is located in a coverage range of a 40MHz bandwidth corresponding to the channel 7.

In one embodiment, the electronic device may determine the channel to be detected according to the initial operating channel by:

the method comprises the steps that the electronic equipment acquires a mode that target equipment accessed by the electronic equipment uses a preset bandwidth on an initial working channel, wherein the mode is one of an upward superposition channel and a downward superposition channel;

and the electronic equipment determines the channel to be detected according to the mode that the target equipment uses the preset bandwidth on the initial working channel and the initial working channel.

It should be noted that, for example, the preset bandwidth is 40MHz, and the initial operating channel of the target device accessed by the electronic device is the channel No. 7 in the 2.4GHz band. The electronic device may first acquire a mode that a target device accessed by the electronic device uses 40MHz bandwidth on channel No. 7. Wherein the method comprises an add-up channel (plus) and a drop-down channel (minus).

It should also be noted that the 40MHz bandwidth is formed by binding two adjacent channels with 20MHz bandwidth together, one is a primary channel, and the other is a secondary channel. The main channel sends beacon messages and part of data messages, and the auxiliary channel sends other messages. If the center frequency of the secondary channel is higher than that of the primary channel when two adjacent 20MHz channels are bundled, it is plus. If the center frequency of the secondary channel is lower than the center frequency of the primary channel when two adjacent 20MHz channels are bundled, it is minus. Both plus and minus are referred to herein as primary channels. For example, the current channel is 7, and the plus is allocated to the 40MHz bandwidth, and another channel needs to be superimposed, that is, the 40MHz bandwidth is formed by the two channels of channel number 7 + channel number 8. minus represents that channel superposition is downward superposition when channel superposition is performed, for example, channel number 7 + channel number 6 constitute a new channel with a bandwidth of 40 MHz.

In this embodiment, the electronic device may obtain a beacon data packet of the target device accessed by the electronic device, and obtain, from the beacon data packet, a mode that the accessed target device uses a 40MHz bandwidth on the initial working channel.

After determining that the target device accessed by the electronic device uses a 40MHz bandwidth on the current working channel, the electronic device may determine the channel to be detected by the following method:

if the target device accessed by the electronic device uses a 40MHz bandwidth mode on the initial working channel as a downward superposition channel, the electronic device determines 8 continuous channels including the initial working channel as a first object channel; the electronic equipment determines other channels except the initial working channel in the first object channel as channels to be detected, wherein the number of the channels, which are lower than the initial working channel, in the channels to be detected is greater than the number of the channels, which are higher than the initial working channel, in the channels to be detected.

Or, if the target device accessed by the electronic device uses the 40MHz bandwidth on the initial operating channel as the upward superposition channel, the electronic device determines 8 continuous channels including the initial operating channel as the second object channel; and the electronic equipment determines other channels except the initial working channel in the second object channel as channels to be detected, wherein the number of the channels, which are lower than the initial working channel, in the channels to be detected is less than the number of the channels, which are higher than the initial working channel, in the channels to be detected.

For example, the initial operating channel is channel No. 7, and the electronic device constructs a channel with a bandwidth of 40MHz by using a downward channel minus superposition manner, so that the electronic device may determine 8 consecutive channels including channel No. 7 as a first object channel, and then determine other channels except channel No. 7 among the 8 channels as channels to be detected, where the number of channels lower than channel No. 7 in the channels to be detected is greater than the number of channels higher than channel No. 7. For example, the 8 consecutive channels including channel No. 7 are channel No. 2, channel No. 3, channel No. 4, channel No. 5, channel No. 6, channel No. 7, channel No. 8, and channel No. 9. Then, the electronic device may determine channels No. 2, No. 3, No. 4, No. 5, No. 6, No. 8, and No. 9 as channels to be detected, where the number of channels lower than the channel No. 7 is 5 (channels No. 2, No. 3, No. 4, No. 5, and No. 6), and the number of channels higher than the channel No. 7 is 2 (channels No. 8 and No. 9). As another example, the 8 consecutive channels including channel No. 7 are channel No. 3, channel No. 4, channel No. 5, channel No. 6, channel No. 7, channel No. 8, channel No. 9, and channel No. 10. Then, the electronic device may determine channels No. 3, 4, 5, 6, 8, 9, and 10 as channels to be detected, where the number of channels lower than the channel No. 7 is 4 (channels No. 3, 4, 5, and 6), and the number of channels higher than the channel No. 7 is 3 (channels No. 8, 9, and 10).

For example, the initial operating channel is channel No. 7, and the electronic device constructs a channel with a bandwidth of 40MHz by using an upward channel plus, so that the electronic device can determine 8 continuous channels including channel No. 7 as the second object channel, and then determine other channels except channel No. 7 among the 8 channels as channels to be detected, where the number of channels lower than channel No. 7 in the channels to be detected is smaller than the number of channels higher than channel No. 7. For example, the 8 consecutive channels including channel No. 7 are channel No. 4, channel No. 5, channel No. 6, channel No. 7, channel No. 8, channel No. 9, channel No. 10, and channel No. 11. Then, the electronic device may determine channels No. 4, 5, 6, 8, 9, 10, and 11 as channels to be detected, where the number of channels below channel No. 7 is 3 (channels No. 4, 5, and 6), and the number of channels above channel No. 7 is 4 (channels No. 8, 9, 10, and 11). As another example, the 8 consecutive channels including channel No. 7 are channel No. 5, channel No. 6, channel No. 7, channel No. 8, channel No. 9, channel No. 10, channel No. 11, and channel No. 12. Then, the electronic device may determine channels 5, 6, 8, 9, 10, 11, and 12 as channels to be detected, where the number of channels lower than channel 7 is 2 (channels 5 and 6), and the number of channels higher than channel 7 is 5 (channels 8, 9, 10, 11, and 12).

203. The electronic equipment obtains the sum of the number of the equipment with the second role working on the initial working channel and the channel to be detected in the environment.

For example, the electronic device may further obtain a sum of the number of devices having the second role and operating on the initial operating channel and the channel to be detected in the environment where the electronic device is located, that is, the electronic device may obtain the number of AP and GO devices operating on the initial operating channel and the channel to be detected in the environment where the electronic device is located.

For example, the initial working channel is a channel No. 7, and the channels to be detected include channels No. 2, 3, 4, 5, 6, 8, and 9. Then, in flow 203, the electronic device may obtain the sum of the number of AP and GO devices operating on channels No. 2, No. 3, No. 4, No. 5, No. 6, No. 7, No. 8, No. 9 in the environment.

204. The electronic equipment scans the initial working channel and the channel to be detected, and acquires the channel idle time and the channel scanning time of each channel during scanning.

205. And according to the channel idle time and the channel scanning time of each channel, the electronic equipment calculates the channel idle ratio of each channel, wherein the channel idle ratio is the ratio of the channel idle time to the channel scanning time.

206. The electronic equipment calculates the average channel idle ratio of the initial working channel and the channel to be detected, and takes the average channel idle ratio and the channel idle ratio of each channel as channel idle parameters.

204, 205, 206 may include, for example:

after the channel to be detected is determined, the electronic device may scan an initial working channel of the target device and the channel to be detected. When scanning the initial working channel and the channel to be detected, the electronic device may obtain a channel idle slot time (channel idle slot time) and a channel scanning time (scan time) of each of the channels.

It should be noted that, in the related art, channel idle slot time (channel idle slot time) and scan time (scan time) are not returned when performing channel scanning. In the embodiment of the present application, information of channel idle time (channel idle slot time) and scan time (scan time) is additionally returned in the scan result of channel scanning.

For example, please refer to fig. 3, fig. 3 is a schematic view of Wi-Fi channel scanning of an extra return channel number (channel number), a channel idle time (channel idle slot time), and a scanning time (scan time) of an electronic device according to an embodiment of the present disclosure. The device comprises a Wi-Fi Driver, a Wi-Fi Firmware, a Wi-Fi Hardware Hardware, a Packet Tx and a Packet Rx, wherein the Wi-Fi Driver is a Wi-Fi driving module, the Wi-Fi Firmware is Wi-Fi Firmware, the Wi-Fi Hardware is Wi-Fi Hardware, the Packet Tx represents a sending data Packet, and the Packet Rx represents a receiving data Packet. That is, when scanning each channel, the electronic device may additionally acquire and return a channel idle slot time (channel idle slot time) and a scan time (scan time). Therefore, when the electronic device scans channels, the electronic device can acquire the channel idle time and the scanning time of each channel.

After the channel idle time and the scanning time of each channel are obtained, the electronic device can calculate a channel idle slot ratio (channel idle slot ratio) corresponding to each channel, wherein the channel idle ratio is a ratio of the channel idle time to the scanning time. For example, the channel idle time of channel No. 2 is 30ms, the scanning time is 50ms, and the channel idle ratio of channel No. 2 is 30ms/50ms — 0.6.

And the electronic equipment can also calculate the average channel idle ratio of the initial working channel and the channel to be detected. That is, the average channel idle ratio is an average value of the sum of the channel idle ratios of the initial operating channel and the channel to be detected.

In this embodiment, the electronic device may use the average channel idle ratio and the channel idle ratios of the channels in the initial working channel and the channel to be detected as channel idle parameters.

207. The electronic equipment acquires the received signal strength of the target equipment accessed by the electronic equipment.

For example, the electronic device may also obtain the received signal strength RSSI of the target device it accesses.

After acquiring the sum of the numbers of the APs and the GO devices operating on the initial operating channel and the channel to be detected in the environment, the channel idle parameters of the initial operating channel and the channel to be detected, and the RSSI of the target device accessed by the electronic device, the electronic device may detect whether the sum of the numbers is less than or equal to a preset first threshold, whether the channel idle parameters satisfy 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. The first condition is that the channel idle ratio of each of the 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.

If the sum of the number is detected to be less than or equal to a first threshold, the channel idle parameter meets a preset first condition, and the RSSI of the target device accessed by the electronic device is greater than or equal to a preset second threshold, 208 may be entered.

208. If the sum of the number is less than or equal to a preset first threshold value, the channel idle parameter meets a first condition, and the received signal strength of the target device is greater than or equal to a preset second threshold value, the electronic device determines a target channel, and performs Wi-Fi communication between the electronic device and the target device through the target channel, wherein the bandwidth of the target channel is greater than that of an initial working channel, and when the channel idle ratio of each of the initial working channel and the channel to be detected is greater than or equal to a preset third threshold value, and the average channel idle ratio is greater than or equal to a preset fourth threshold value, it is determined that the channel idle parameter meets the first condition.

For example, if 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 received signal strength of the target device accessed by the electronic device is greater than or equal to a preset second threshold, it may be considered that the interference in the environment where the electronic device is currently located is small. In this case, the electronic device may determine a target channel and perform Wi-Fi communication between the electronic device and the target device over the target channel. Wherein the bandwidth of the target channel may be greater than the bandwidth of the initial operating channel. For example, the bandwidth of the target channel is 40MHz bandwidth. Wherein, the channel idle parameter satisfies a first condition, which may indicate that the associated channel is idle. For example, the electronic device may construct a target channel with a bandwidth of 40MHz using channel No. 7 as a primary channel and channel No. 6 as a secondary channel for Wi-Fi communication between the electronic device and a target device accessed by the electronic device.

Otherwise, the electronic device may continue to use the 20MHz bandwidth of channel No. 7 for Wi-Fi communications between the electronic device and the AP or GO device to which it has access.

It can be understood that, in this embodiment of the application, when the sum of the numbers of the AP devices and the GO devices that operate on the initial operating channel and the channel to be detected in the environment is smaller than a preset first threshold, the channel idle ratios of the channels in the initial operating channel and the channel to be detected are both greater than or equal to a preset third threshold, the average channel idle ratio is greater than or equal to a preset fourth threshold, and the RSSI of the target device that the electronic device accesses is greater than or equal to a preset second threshold, it may be considered that the interference of the environment where the electronic device is located is smaller. In the case of less interference in the environment, the electronic device may use a 40MHz bandwidth channel for Wi-Fi communications. And in the case of large interference in the environment, the electronic device can use a channel with a bandwidth of 20MHz for Wi-Fi communication. Since the Wi-Fi communication transceiving performance of the 40MHz bandwidth channel is better than that of the 20MHz bandwidth channel, in this embodiment, under the condition that the environmental interference is small, the electronic device may have better communication performance by using the 40MHz bandwidth channel for Wi-Fi communication.

In another embodiment, the medium ready count may also be used as a 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, and when the number is small, for example, the value of the parameter medium ready count within 500ms is less than 100, it can be considered that the interference on the corresponding channel is small.

For example, when it is detected that the sum of the numbers of the access points and the group owner devices operating on the initial operating channel and the channel to be detected in the environment is less than or equal to a preset first threshold, the number of the medium ready count is less than a preset number, 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 may be considered that the current environment interference is small. In this case, the electronic device may use a target channel having a preset bandwidth (e.g., 40MHz bandwidth) and a target device accessed by the electronic device for Wi-Fi communication.

Referring to fig. 4, fig. 4 is a third flowchart illustrating an apparatus control method according to an embodiment of the present disclosure. The device control method may be applied to an electronic device, which may be a device having a second role that is an Access Point (AP) role or a Group Owner (GO) role. The flow of the device control method may include:

301. an initial operating channel of the electronic device is determined.

In the embodiment of the present application, for example, when a device in an STA role or a GC role accesses an electronic device in an AP role or a GO role and needs to determine what bandwidth is used for a working channel between the electronic device and the AP role, the electronic device may first acquire a current working channel (i.e., an initial working channel) of the electronic device. For example, the electronic device currently operates on channel number 7 in the 2.4GHz band.

302. And determining a channel to be detected according to the initial working channel, wherein the channel to be detected is positioned in a preset bandwidth range corresponding to the initial working channel.

For example, after an initial working channel of the electronic device is determined, the electronic device may determine a channel to be detected according to the initial working channel, where the channel to be detected is located within a preset bandwidth range corresponding to the initial working channel.

For example, the preset bandwidth is 40 MHz. Then, the electronic device in the process 302 may determine, according to the initial operating channel of the electronic device, a channel to be detected, where the channel to be detected is located in a coverage range of a 40MHz bandwidth corresponding to the initial operating channel. How to determine the channel to be detected according to the initial working channel is described in detail above, and is not described here again.

303. And acquiring the sum of the number of the devices with the second role working on the initial working channel and the channel to be detected in the environment.

For example, the electronic device may further obtain the number of AP and GO devices operating on the initial operating channel and the channel to be detected in the environment where the electronic device is located.

For example, the initial working channel is a channel number 7, and the channels to be detected include channels number 2, 3, 4, 5, 6, 8, and 9. Then, in flow 303, the electronic device may obtain the sum of the number of AP and GO devices operating on channels No. 2, No. 3, No. 4, No. 5, No. 6, No. 7, No. 8, No. 9 in the environment.

304. And acquiring channel idle parameters of the initial working channel and the channel to be detected.

305. And acquiring the sum of the received signal strengths of other devices with the second role in the environment, which work on the initial working channel and the channel to be detected.

For example, the electronic device may also obtain the sum of the RSSI of other APs and GO devices operating on the initial operating channel and the channel to be detected in the environment.

Then, the electronic device may detect whether the sum of the numbers is less than or equal to a preset first threshold, whether the channel idle parameter satisfies the first condition, and whether the sum of the received signal strengths of the other devices having the second role is less than or equal to a preset fifth threshold. If so, flow may proceed to 306. Otherwise, the electronic device may perform other operations.

306. If the sum of the number is detected to be smaller than or equal to a preset first threshold value, the channel idle parameter meets a first condition, and the sum of the received signal strengths of other devices with second roles is detected to be smaller than or equal to a preset fifth threshold value, a target channel is determined, and Wi-Fi communication between the electronic device and the connected device with the first role is performed through the target channel, wherein the bandwidth of the target channel is larger than that of the initial working channel, and the first role is a workstation role or a group client role.

For example, if the electronic device detects that the sum of the number is less than or equal to a preset first threshold, the channel idle parameter meets the first condition, and the sum of the RSSI of the other access points and the group owner device operating on the initial operating channel and the channel to be detected is less than or equal to a preset fifth threshold, it may be considered that the interference in the environment where the electronic device is currently located is small. In this case, the electronic device may determine a target channel, and perform Wi-Fi communication between the electronic device and a device connected thereto and having a first role through the target channel, where a bandwidth of the target channel is greater than a bandwidth of the initial working channel, and the first role is a workstation role or a group client role. For example, the electronic device may configure a target channel with a bandwidth of 40MHz by using the channel No. 7 as a primary channel and the channel No. 6 or the channel No. 8 as a secondary channel, and perform Wi-Fi communication based on the target channel with the bandwidth of 40MHz and the corresponding STA or GC device. Otherwise, the electronic device may still use channel number 7 with 20MHz bandwidth for Wi-Fi communication between the electronic device and its corresponding STA or GC device.

It can be understood that in the embodiment of the application, the electronic device can use a channel with a larger bandwidth for Wi-Fi communication in an environment with less interference, so that the performance of data transmission by using a Wi-Fi connection is improved.

In one embodiment, the channel idle parameter in 306 may be a channel idle ratio of each of an initial operating channel and a channel to be detected of the electronic device. Then, the first condition that the channel idle parameter satisfies the preset condition may be that the channel idle ratios of the channels in the initial operating channel and the channel to be detected of the electronic device are both greater than or equal to a preset third threshold.

Alternatively, the channel idle parameter in 306 may be the channel idle ratio of each of the initial operating channel and the channel to be detected of the electronic device and the average channel idle ratio of these channels. Then, the first condition that the channel idle parameter satisfies the preset condition may be that the channel idle ratios of the channels in the initial operating channel and the channel to be detected of the electronic device are both greater than or equal to a preset third threshold, and the average channel idle ratio of the channels is greater than or equal to a preset fourth threshold.

Referring to fig. 5 to 6, fig. 5 to 6 are schematic views of a scenario of an apparatus control method according to an embodiment of the present disclosure.

For example, with the electronic device D1 and the electronic device D2, the user wants to wirelessly project the audio and video files on the electronic device D2 onto the electronic device D1 for playing. The user may turn on the Wi-Fi functionality of electronic devices D1 and D2, thereby establishing a Wi-Fi P2P connection between electronic devices D1 and D2, as shown in FIG. 5.

Through the negotiation, the electronic device D1 is determined as the role of the group owner GO, and the electronic device D2 is determined as the role of the group client GC. The working channel of the GO device D1 is, for example, channel number 7 in the 2.4GHz band. Before establishing the normal connection, the GC device D2 may first acquire the current operating channel, i.e., channel No. 7, of the GO device D1. Among other things, the GO device D1 supports a 20MHz bandwidth and a 40MHz bandwidth.

Thereafter, the GC device D2 may determine the channel to be detected according to channel No. 7 of the current operating channel of the GO device D1. For example, the way the GO device D1 uses 40MHz bandwidth on channel No. 7 is to superimpose channel minus downward. Then, the channels to be detected may be, for example, channels No. 2, No. 3, No. 4, No. 5, No. 6, No. 8, No. 9.

Thereafter, the GC device D2 may scan each of channels No. 2 to 9 to obtain the sum of the number of APs and GO devices operating in the surrounding environment on channels No. 2 to 9.

Also, when scanning each of the channels No. 2 to 9, the GC device D2 may additionally acquire a channel idle time (channel idle slot time) and a channel scan time (scan time) of each channel. Based on the channel idle time and the channel scan time of each channel, the GC device D2 may calculate a channel idle ratio of each channel, where the channel idle ratio is a ratio of the channel idle time and the channel scan time. Also, after calculating the channel idle ratio of each channel, the GC device D2 may also calculate an average channel idle ratio.

Thereafter, the GC device D2 may also obtain the received signal strength RSSI of the GO device D1 that it accesses.

After acquiring the above information, the GC device D2 may detect whether a sum of the numbers of APs and GO devices operating in 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), detect whether the channel idle ratios of the channels 2 to 9 are greater than or equal to a preset third threshold (for example, the preset third threshold is 10% or 20% or the like), detect whether the average channel idle ratio of the channels is greater than or equal to a preset fourth threshold (for example, the preset fourth threshold is 15% or 25% or the like), and detect whether the RSSI of the received signal strength 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 or the like).

For example, in this embodiment, the detection results of the above four conditions are that, for example, the GC device D2 detects that the number of APs and GO devices operating in channels 2 to 9 in the surrounding environment is 5 and less than 7 preset first thresholds, detects that the channel idle ratio of each channel from channel 2 to channel 9 is greater than 10% of the preset third threshold, and detects that the average channel idle ratio of each channel is 30% and greater than 15% of the preset fourth threshold, and detects that the RSSI-50 dBm of the received signal strength of the GO device D1 is greater than-75 dBm of the preset second threshold. In this case, the GC device D2 may determine that a 40MHz bandwidth channel may be used for Wi-Fi communication with the GO device D1. For example, the devices D1 and D2 may constitute a 40MHz bandwidth channel with the channel No. 7 as a primary channel and the channel No. 6 as a secondary channel, and use the 40MHz bandwidth channel for Wi-Fi communication, as shown in fig. 6.
