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.
It is understood that the execution subject of the embodiment of the present application may be an electronic device such as a smart phone or a tablet computer.
Referring to fig. 1, fig. 1 is a schematic flow chart of 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 Wi-Fi device. The flow of the device control method may include:
101. the received signal strength of an access point operating on each channel in an environment is obtained.
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 electronic device has poor flexibility in selecting a Wi-Fi operating channel. For example, in the related art, the electronic device may select a Wi-Fi operating channel completely randomly.
In the embodiment of the present application, for example, the electronic device may first acquire the Received Signal Strength (RSSI) of the access point operating on each Wi-Fi channel in the environment where the electronic device is located.
For example, 13 channels in the 2.4GHz band are respectively denoted as channel No. 1 (center frequency 2412MHz, channel bottom frequency 2401MHz, channel high end frequency 2423MHz), channel No. 2 (center frequency 2417MHz, channel bottom frequency 2406MHz, channel high end frequency 2428MHz), channel No. 3 (center frequency 2422MHz, channel bottom frequency 2411MHz, channel high end frequency 2433MHz), … …, and channel No. 13 (center frequency 2472MHz, channel bottom frequency 2461MHz, channel high end frequency 2483 MHz). The electronic device may first obtain the received signal strength of the access point operating on channel number 1 and then obtain the received signal strength of the access point operating on channel number 2, … … and obtain the received signal strength of the access point operating on channel number 13.
It should be noted that if there are 2 or more than 2 access points operating on a certain channel, the electronic device needs to acquire the received signal strength of each access point in the 2 or more than 2 access points. For example, if the electronic device is located in an environment where there are 2 access points operating on channel No. 1, which are a and B, respectively, the electronic device needs to acquire the received signal strength of access point a and the received signal strength of access point B, respectively.
102. And acquiring the numerical value of the channel idle parameter corresponding to each channel, wherein the channel idle parameter is used for expressing the idle degree of each channel.
For example, the electronic device may further obtain a value of a channel idle parameter corresponding to each channel, where the channel idle parameter is a parameter used to indicate an idle degree of each channel.
103. And determining a target channel according to the received signal strength of the access point working on each channel and the value of the channel idle parameter corresponding to each channel.
104. And determining the target channel as a working channel when the electronic equipment is in Wi-Fi connection.
For example, 103 and 104 may include:
after the received signal strength of the access point working on each channel and the value of the channel idle parameter corresponding to each channel are obtained, the electronic device can determine a target channel according to the received signal strength and the value of the channel idle parameter. The electronic device may then determine the target channel as a working channel for use by the electronic device in making Wi-Fi connections.
It can be understood that, in the embodiment of the present application, when the electronic device performs a Wi-Fi connection, a target channel may be determined according to the received signal strength of the access point operating on each channel and the vacancy degree of each channel, and the target channel is used as an operating channel of the Wi-Fi connection. Therefore, the flexibility of selecting the Wi-Fi working channel by the electronic equipment can be improved.
Referring to fig. 2, fig. 2 is another schematic flow chart of an apparatus control method according to an embodiment of the present disclosure. The device control method can be applied to electronic devices, and the electronic devices can be devices which are used as group owners in a Wi-Fi Direct function architecture. The flow of the device control method may include:
201. the electronic device obtains received signal strengths of access points operating on channels in the environment.
In the related art, the performance of data transmission by using Wi-Fi connection is poor. For example, in the related art, when selecting an operating channel, a Wi-Fi device selects an operating channel either completely randomly or according to the number of access points operating on each channel. The working channel selected in a random manner may be a crowded working channel, and the interference on the channel may be large, resulting in poor performance of subsequent Wi-Fi connection communication. Since the number of access points and the interference degree of the working channel are not absolute corresponding, the channel selected by selecting the working channel according to the number of access points working on each channel may also be a channel with large interference, which may also result in poor performance of subsequent Wi-Fi connection communication.
In an embodiment of the present application, the electronic device may be a device that is a group owner in a Wi-Fi Direct function architecture.
It should be noted that 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 used to facilitate the playback of video/audio presentations at the 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. Wherein the group owner GO acts like an access point AP in an Infrastructure BSS. And the group client GC functions like a station STA in an Infrastructure BSS. Before the P2P Group (i.e., P2P Network) is established, 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 role of GO, and the other P2P Device will play the role of GC.
For example, before formal connection between the electronic device as GO device and the GC device, a full channel scan (Scanning) may be performed to determine the working channel when GO is used. When performing a full channel scan, the electronic device may obtain the Received Signal Strength (RSSI) of the access point AP operating on each channel.
For example, 13 channels in the 2.4GHz band are denoted as channel No. 1, channel No. 2, channel No. 3, … …, and channel No. 13, respectively. The electronic device may first obtain the received signal strength of the access point operating on channel number 1 and then obtain the received signal strength of the access point operating on channel number 2, … … and obtain the received signal strength of the access point operating on channel number 13.
It should be noted that if there are 2 or more than 2 access points operating on a certain channel, the electronic device needs to acquire the received signal strength of each access point in the 2 or more than 2 access points. For example, in an environment where the electronic device is located, there are 2 access points operating on channel No. 1, which are a and B, respectively, and then the electronic device needs to acquire the received signal strength corresponding to access point a and the received signal strength corresponding to access point B, respectively.
202. The electronic equipment acquires a channel idle ratio corresponding to each channel, wherein the channel idle ratio is the ratio of channel idle time acquired in each scanning process to scanning time.
For example, when the electronic device scans channels, it may also obtain channel idle time (channel idle slot time) and scan time (scan time) corresponding to each channel.
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, referring to fig. 3, fig. 3 is a schematic view of a Wi-Fi channel scan of an electronic device additionally returning a channel number (channel number), a channel idle time (channel slot time), and a scan time (scan time) when performing channel scan according to an embodiment of the present application. The Wi-Fi Driver is a Wi-Fi drive module, the Wi-Fi Firmware is Wi-Fi Firmware, the Wi-Fi Hardware is Wi-Fi Hardware, the Packet Tx is a sending data Packet, and the Packet Rx is a receiving data Packet. That is, the electronic device may additionally acquire and return a channel idle slot time (channel idle slot time) and a scan time (scan time) when scanning each channel. 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. 1 is 30ms, the scanning time is 50ms, and the channel idle ratio of channel No. 1 is 30ms/50ms — 0.6.
203. For each channel, the electronic device calculates the sum of the received signal strength scores of the access points operating on the channel, wherein the electronic device sets different scores for different received signal strengths.
For example, in the embodiment, the electronic device may set different scoring values for different received signal strengths in advance. For example, when the value of the received signal strength is less than-75 dBm, the score of each received signal strength is 1 point. When the value of the received signal strength is [ -75dBm, -55dBm), each received signal strength is scored as 3 points. When the value of the received signal strength is [ -55dBm,0dBm), the score of each received signal strength is 5 points.
Based on this, after acquiring the received signal strengths of the access points operating on the respective channels, the electronic device may calculate the sum of the scores of the received signal strengths of the access points operating on the respective channels. For example, 2 ap's operate on channel 1, where the received signal strength corresponding to one ap is-50 dBm, and the corresponding score is 5, and the received signal strength corresponding to the other ap is-70 dBm, and the corresponding score is 3. Then, the sum of the received signal strength scores for channel number 1 is 5+3 to 8. For another example, if 1 access point operates on channel 6, and the received signal strength corresponding to the access point is-30 dBm, the corresponding score value is 5. Then the sum of the received signal strength scores for channel number 6 is 5.
Through the process of 203, the electronic device may calculate the sum of the scores of the received signal strengths corresponding to the channels.
204. The electronic equipment calculates the channel busy ratio of each channel, wherein the channel idle ratio is recorded as R1The channel busy ratio is denoted as R2Then R is2＝1-R1。
For example, after the channel idle ratio corresponding to each channel is calculated in 202, the electronic device may calculate the channel busy ratio of each channel, where the channel idle ratio is denoted as R1The channel busy ratio is denoted as R2Then R is2＝1-R1. For example, the channel idle ratio of channel No. 1 is 0.6, and the channel busy ratio of channel No. 1 is 1-0.6-0.4.
Through the process of 204, the electronic device may calculate a channel busy ratio of each channel. The larger the value of the channel busy ratio, the more busy and congested the channel is.
205. The electronic device obtains a first weight corresponding to the sum of the credit values and a second weight corresponding to the channel busy ratio.
206. According to the first weight and the second weight, the electronic equipment calculates the weighted sum of the credit values of all the channels and the busy ratio of the channels.
207. The electronic device determines the channel with the smallest weighted sum as the target channel.
For example, 205, 206, and 207 may include:
after calculating the sum of the scores of the received signal strength corresponding to each channel and the channel busy ratio of each channel, the electronic device may obtain a first weight corresponding to the sum of the scores and a second weight corresponding to the channel busy ratio. Then, the electronic device may calculate a weighted sum of the credit values of the channels and the channel busy ratio according to the first weight and the second weight, and determine a channel with the smallest weighted sum as the target channel.
For example, the first weight is 30% and the second weight is 70%. For example, if the sum of the score values of channel number 1 is 8 and the channel busy ratio is 0.4, then their weighted sum is 8 × 30% +0.4 × 70% — 2.68. As another example, if the sum of the score values of channel No. 6 is 5 and the channel busy ratio is 0.5, then their weighted sum value is 5 × 30% +0.5 × 70% — 1.85.
Of course, in other embodiments, the first weight and the second weight may have other values, such as 40% for the first weight, 60% for the second weight, and so on. The present embodiment does not specifically limit the magnitude of the first weight and the second weight.
Through the process of 206, the electronic device may calculate a weighted sum of the channels. The electronic device may then determine the channel with the smallest weighted sum as the target channel. It will be appreciated that a smaller weighted sum indicates that the corresponding channel is more free and less interfered with. The target channel is subject to minimal interference.
208. The electronic device determines the target channel as the working channel when the Wi-Fi connection is made.
For example, after determining the target channel, the electronic device may determine the target channel as an operating channel used by the electronic device when making a Wi-Fi connection. That is, in this embodiment, when the electronic device is used as the group owner GO in the Wi-Fi Direct function architecture, the electronic device may select a channel with the minimum interference degree as the working channel. Because the target channel is minimally interfered, the electronic equipment can obtain better performance when data transmission is carried out by utilizing the Wi-Fi connection.
It can be understood that, in the embodiment of the present application, on one hand, when the electronic device performs a Wi-Fi connection, a target channel may be determined according to the received signal strength of the access point operating on each channel and the vacancy degree of each channel, and the target channel is used as an operating channel of the Wi-Fi connection. Therefore, the flexibility of selecting the Wi-Fi working channel by the electronic equipment can be improved. On the other hand, because the target channel is the channel with the minimum interference degree, in the embodiment of the application, the electronic device may select a working channel with the minimum interference degree and the most suitable working channel for the Wi-Fi connection, so as to improve the performance of the electronic device for data transmission by using the Wi-Fi connection.
In another embodiment, in addition to determining the target channel according to the sum of the credit values of the channels and the channel busy ratio, the electronic device may further obtain a value of a parameter medium ready count during channel scanning, and determine the target channel according to the received signal strength of the access point operating on each channel and the value of the parameter medium ready count.
It should be noted that 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, the electronic device may calculate a sum obtained by adding the sum of the credit values of the channels to the numerical value of the medium ready count, and determine the channel with the smallest sum as the target channel.
In yet another embodiment, in addition to determining the target Channel according to the sum of the credit values of the channels and the Channel busy ratio, the electronic device may obtain a value of Clear Channel Assessment (CCA) during Channel scanning, and determine the target Channel according to the received signal strength of the access point operating on each Channel and the value of the parameter CCA.
It should be noted that the value of the parameter CCA may also be effective to indicate whether the channel is clear. The channel may be considered more clear when the value of CCA is smaller. For example, the electronic device may calculate a sum of the credit values of the channels and the value of CCA, and determine the channel with the smallest sum as the target channel.
Of course, in some other embodiments, the electronic device may determine the target channel only according to the value of the parameter medium ready count or the value of the parameter CCA. For example, the electronic device may determine a channel with the smallest value of the parameter medium ready count or the smallest value of the parameter CCA as the target channel, and so on.
It should be noted that the channel selection scheme provided in the embodiment of the present application may also be applied in a non-Wi-Fi P2P application scenario, for example, at time T1, a certain access point AP is started, and at this time, the access point has not established a Wi-Fi connection with any station STA yet. Then, after the startup, the access point may select a target channel with the least interference as an operating channel using the channel selection scheme provided in the embodiment of the present application. At a time T2, which is a time after T1, when a station needs to connect to the access point for a Wi-Fi connection, the access point may establish a Wi-Fi connection with the station based on the selected working channel, thereby improving the performance of Wi-Fi connection communication between the access point AP and the station STA.
Referring to fig. 4 to 5, fig. 4 to 5 are schematic views of a scenario of an apparatus control method according to an embodiment of the present application.
For example, with the electronic device D1 and the electronic device D2, the user wants to wirelessly project the audiovisual file on the electronic device D2 onto the electronic device D1 for playing. The user may open the Wi-Fi functions of electronic devices D1 and D2, thereby establishing a Wi-Fi P2P connection between electronic devices D1 and D2, as shown in FIG. 4.
Through the negotiation, the electronic device D1 is determined to have the role of the group owner GO, and the electronic device D2 is determined to have the role of the group client GC. Before establishing the normal connection, the electronic device D1 may perform a full channel scan to determine its operating channel as the group owner GO.
In the channel scanning process, the electronic device D1 may first obtain the channel idle time and the scanning time corresponding to each channel, and calculate the channel idle ratio of each channel, where the channel idle ratio is a ratio of the channel idle time to the scanning time. For example, the channel idle time of the channel No. 1 acquired by the electronic device D1 is 30ms, the scanning time is 50ms, and the channel idle ratio of the channel No. 1 is 30ms/50ms — 0.6.
After acquiring the channel idle ratio of each channel, the electronic device D1 may calculate the channel busy ratio of each channel, where the channel idle ratio is denoted as R1The channel busy ratio is denoted as R2Then R2＝1-R1. For example, the channel idle ratio of channel No. 1 is 0.6, and the channel busy ratio of channel No. 1 is 1-0.6-0.4.
Also, the electronic device D1 may acquire the received signal strength RSSI of the APs operating on the respective channels in the surrounding environment. For example, the electronic device D1 detects that 1 AP in the surrounding environment operates on channel number 6, and the received signal strength corresponding to the AP is-30 dBm. And the electronic device D1 detects that 2 APs in the surrounding environment operate in channel 1, and the received signal strengths of the two APs are-70 dBm and-50 dBm, respectively. In the embodiment of the present application, the electronic device D1 is preset with different scoring values for different received signal strengths. For example, when the value of the received signal strength is less than-75 dBm, the score of each received signal strength is 1 point. When the value of the received signal strength is [ -75dBm, -55dBm), each received signal strength is scored as 3 points. When the value of the received signal strength is [ -55dBm,0dBm), the score of each received signal strength is 5 points.
Then, for each channel, the electronic device D1 may calculate the sum of the scores corresponding to the received signal strengths of the access points operating on the channel. For example, the sum of the received signal strength scores for channel No. 1 is 5+3 to 8, and the sum of the received signal strength scores for channel No. 6 is 5.
Thereafter, the electronic device D1 may perform weighted summation on the sum of the scores of the channels and the channel busy ratio according to a first weight corresponding to the sum of the scores and a second weight corresponding to the channel busy ratio, and determine the channel with the smallest weighted sum as the target channel. For example, the first weight is 30% and the second weight is 70%. For example, if the sum of the score values of channel number 1 is 8 and the channel busy ratio is 0.4, then their weighted sum is 8 × 30% +0.4 × 70% — 2.68. As another example, if the sum of the score values of channel No. 6 is 5 and the channel busy ratio is 0.5, then their weighted sum value is 5 × 30% +0.5 × 70% — 1.85.
It will be appreciated that a smaller weighted sum indicates that the corresponding channel is more free and less interfered with. Therefore, the determined target channel is the channel with the least interference.
After determining the target channel, the electronic device D1 may determine the target channel as the working channel used by the electronic device when making a Wi-Fi connection. For example, the electronic device D1 determines channel No. 11 as the target channel, and the electronic device D1 and the electronic device D2 may perform Wi-Fi connection and communication based on channel No. 11, as shown in fig. 5.
It can be understood that, because the wireless screen projection has a high performance requirement on data transmission, the channel selection scheme provided by the embodiment of the application can enable the Wi-Fi communication connection performance between the devices to be better, so that the wireless screen projection performance is improved, for example, the speed and stability when data are transmitted through Wi-Fi connection, and the like, and better experience is brought to users.
Referring to fig. 6, fig. 6 is a schematic structural diagram of an apparatus control device according to an embodiment of the present disclosure. The device control apparatus may be applied to an electronic device, which may be a Wi-Fi device.
