Background technique

Wi-Fi technology is a wireless local area network technology established by the Wi-Fi Alliance in the Institute of Electrical and Electronic Engineers (IEEE) 802.11 standard. Wi-Fi technology usually involves two types of devices: access point (Access Point, AP) and station (station, STA). Among them, the AP can also be called a wireless access point, which is a Wi-Fi network provider, allows other wireless devices to access, and provides data access for the connected devices. A device connected to a Wi-Fi network can be called an STA. For example, electronic devices that support Wi-Fi functions, such as mobile phones, tablets, and laptops, can be used as STAs.

At present, the process of STA (for example, STA is a mobile phone) accessing the Wi-Fi network provided by the AP is: the user selects the Wi-Fi network that the mobile phone wants to access on the mobile phone. For example, the user can select the service set identifier (SSID) of the Wi-Fi network that the mobile phone wants to access in the wireless local area network setting interface of the mobile phone. In response to the user's selection, the mobile phone displays a password input interface for the user to enter the Wi-Fi network access password. After the user enters the access password, the mobile phone can carry the Wi-Fi configuration information in the connection request and transmit it to the AP that provides the Wi-Fi network. The Wi-Fi configuration information includes at least the access password input by the user and the SSID of the Wi-Fi network. After receiving the connection request, the AP verifies the Wi-Fi configuration information in the connection request. If the verification is passed, the access of the mobile phone is approved, and if the verification fails, the access of the mobile phone is rejected.

It is understandable that, in the above process, the user manually inputting the access password is a prerequisite for the STA to access the Wi-Fi network, and this affects the speed at which the STA can access the Wi-Fi network.

detailed description

Hereinafter, the terms “first” and “second” are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of these features. In the description of the present embodiment, unless otherwise specified, "plurality" means two or more.

At present, electronic devices that support Wi-Fi functions such as mobile phones can be used as STAs to access the Wi-Fi network provided by the AP to achieve data access. In order to ensure the security of the network connection, the Wi-Fi network provided by the AP is usually encrypted. That is, before the electronic device as a STA accesses the Wi-Fi network provided by the AP, the AP needs to authenticate the Wi-Fi configuration information carried in the connection request sent by the electronic device. If the authentication is passed, the electronic device is allowed to access, otherwise the electronic device is rejected. Among them, the Wi-Fi configuration information includes at least: the SSID and access password of the Wi-Fi network. The Wi-Fi configuration information may also include the encryption method of the Wi-Fi network.

For electronic devices with display screens, such as mobile phones and tablet computers, the access password can be manually input by the user. However, manually entering the access password will affect the speed at which the electronic device accesses the Wi-Fi network. In addition, with the advancement of technology, more and more smart home devices support Wi-Fi functions. Some smart home devices, such as desk lamps, speakers, air conditioners, etc., do not have a display screen, that is, they cannot provide a password input interface for users to enter the access password. Therefore, if users are allowed to avoid entering the access password on the side of the electronic device as a STA, it will not only increase the speed of the electronic device accessing Wi-Fi network, but also provide a way for electronic devices without a display screen to access the Wi-Fi network. It's possible.

The prior art provides a solution for preventing the user from inputting the access password on the side of the electronic device serving as the STA. Taking the electronic device as a desk lamp as an example, the specific process is as follows: First, the user presses the factory reset button of the desk lamp. In response to the user's operation of the button, the desk lamp broadcasts a Wi-Fi beacon frame. When the AP is working, it will monitor all the channels that can be used for Wi-Fi transmission. Therefore, the AP can receive the Wi-Fi beacon frame broadcast by the desk lamp. After that, the prompt light corresponding to the AP will flash, prompting the user that there is a device that needs to be accessed. The user can operate the corresponding button set on the AP to indicate that the device is allowed to access. In response to the user's operation of the corresponding button on the AP, the AP encrypts the Wi-Fi configuration information (such as including SSID, access password, and encryption method) of the Wi-Fi network provided by it and stores the fragments in multiple multicast packets ( At least dozens of multicast packets are required to send the last two bytes of the destination Internet Protocol (IP) address, and send these multiple multicast packets. The encryption key is pre-configured in the AP and lamp. After the desk lamp receives these multiple multicast packets, it splices the multiple multicast packets, and uses the preset encryption key to parse them to obtain the Wi-Fi configuration information. Finally, the desk lamp sends a connection request carrying Wi-Fi configuration information to the AP. After the AP receives the connection request, it authenticates the Wi-Fi configuration information. After the authentication is passed, the desk lamp is allowed to access. So far, the desk lamp has successfully connected to the Wi-Fi network provided by the AP.

It can be seen that in the solution provided by the prior art that does not require the user to enter the access password, the electronic device as the STA needs to receive multiple multicast packets for splicing to obtain the corresponding Wi-Fi configuration information, which still cannot be used. Electronic devices quickly connect to Wi-Fi networks. In addition, the access process requires the user to perform multiple operations, and the user experience is not good.

The embodiment of the present application provides a Wi-Fi connection method. After the Wi-Fi function of the electronic device is turned on, the electronic device can broadcast a probe request frame to scan for available APs around it. After the AP detects the probe request frame, it may reply to the electronic device a probe response frame carrying Wi-Fi configuration information of the Wi-Fi network provided by the AP. After receiving the probe response frame, the electronic device can access the Wi-Fi network provided by the AP according to the Wi-Fi configuration information in the probe response frame. In this way, the user does not need to manually enter the access password, and only needs to receive a probe response frame to obtain the Wi-Fi configuration information required to access the Wi-Fi network to complete the access, which improves the access of the electronic device to the Wi-Fi network. The speed of the Fi network. In addition, there is no need for the user to perform multiple operations, which improves the user's operating experience.

Exemplarily, the electronic devices described in the embodiments of the present application may be mobile phones, tablet computers, desktop computers, laptops, handheld computers, notebook computers, ultra-mobile personal computers (UMPC), and netbooks. As well as cellular phones, personal digital assistants (PDAs), smart home devices such as desk lamps, speakers, air conditioners, rice cookers, televisions, and augmented reality (AR)\virtual reality (VR) devices, etc. Devices that support Wi-Fi functions. In this embodiment of the application, the AP may be a router. The AP may also be an electronic device with AP capability (for example, capable of providing a Wi-Fi network), such as a mobile phone, that is, an electronic device with AP capability may be used as an AP. The embodiments of the present application do not impose special restrictions on the specific forms of the AP and the electronic device that is used as a STA to access the Wi-Fi network provided by the AP.

In some embodiments, the angular velocity of the electronic device around three axes (ie, x, y, and z axes) can be determined by the gyroscope sensor 180B. The gyro sensor 180B can be used for image stabilization. Exemplarily, when the shutter is pressed, the gyroscope sensor 180B detects the angle of the shake of the electronic device, calculates the distance that the lens module needs to compensate according to the angle, and allows the lens to counteract the shake of the electronic device through a reverse movement to achieve anti-shake.

The methods in the following embodiments can all be implemented in an electronic device having the above hardware structure.

FIG. 2 is a schematic flowchart of a Wi-Fi connection method provided by an embodiment of the application. As shown in Figure 2, the method may include:

S201. After the Wi-Fi function of the electronic device is turned on, the electronic device sends a probe request frame.

Among them, after the Wi-Fi function of the electronic device is turned on, the electronic device can broadcast a probe request frame on a channel that can be used for Wi-Fi transmission to scan for available APs around it.

In some embodiments, the electronic device may enable the Wi-Fi function of the electronic device after receiving the user's first operation. The first operation is an operation for the user to turn on the Wi-Fi function of the electronic device. Exemplarily, the first operation may be an operation of a button for turning on the Wi-Fi function of the electronic device by the user. The button may be a virtual button displayed on the display screen of the electronic device, or may be a physical button set in the electronic device.

For example, if the electronic device is a device with a display screen, such as a mobile phone, the first operation is an operation of a virtual button displayed on the display screen of the mobile phone, such as a switch button of a wireless local area network. As shown in FIG. 3, the user can click the switch button 302 of the wireless LAN in the wireless LAN setting interface 301 of the mobile phone. In response to the click operation, the mobile phone can turn on the Wi-Fi function of the mobile phone. After the Wi-Fi function of the mobile phone is turned on, the mobile phone can broadcast a probe request frame on a channel that can be used for Wi-Fi transmission to scan for available APs around it.

For another example, if the electronic device is a device without a display screen, such as a desk lamp, the first operation is the operation of a physical button set in the desk lamp, such as a factory reset button. As shown in Fig. 4, the user can operate the factory reset button 401 of the desk lamp. In response to this operation, the desk lamp can turn on the Wi-Fi function of the desk lamp. After the Wi-Fi function of the desk lamp is turned on, the desk lamp can broadcast probe request frames on the channels available for Wi-Fi transmission to scan for available APs around it.

S202. The AP receives a probe request frame from the electronic device.

When the AP is working, it will monitor all channels available for Wi-Fi transmission. Therefore, after the electronic device broadcasts the probe request frame on a channel that can be used for Wi-Fi transmission, the AP can receive the probe request frame from the electronic device. Combining the example in S201, for example, the AP may receive a probe request frame from a mobile phone. For another example, the AP may receive the probe request frame from the desk lamp.

S203. The AP sends a probe response frame to the electronic device, where the probe response frame carries Wi-Fi configuration information of the Wi-Fi network provided by the AP.

Among them, the Wi-Fi configuration information is used for the electronic device to access the Wi-Fi network provided by the AP. The Wi-Fi configuration information includes at least: the SSID and access password of the Wi-Fi network. The Wi-Fi configuration information may also include the encryption method of the Wi-Fi network.

In some embodiments, after the AP receives the probe request frame from the electronic device, the Wi-Fi configuration information of the Wi-Fi network provided by the AP may be carried in the probe response frame and sent to the electronic device.

In some other embodiments, after the AP receives the probe request frame from the electronic device, it may carry the Wi-Fi configuration information of the Wi-Fi network provided by the AP in the probe response when determining that it meets the secret-free access rule. The frame is sent to the electronic device. In other words, secret-free access rules can be set on the AP side. After the AP receives the probe request frame from the electronic device, if it determines that the secret-free access rule is met, it indicates that the electronic device is allowed to access secret-free, that is, the user is not required to enter a password. At this time, the AP may carry the Wi-Fi configuration information required to access the Wi-Fi network in a probe response frame and send it to the electronic device.

Exemplarily, the secret-free access rules set on the AP side may include one or more of the following: electronic devices in the whitelist allow secret-free access, electronic devices located within a certain distance from the AP allow secret-free access, and during a specific time period It allows secret-free access of electronic devices, etc.

Among them, take the secret-free access rule including the electronic devices in the whitelist allowing secret-free access as an example. The whitelist may include one or more identities of electronic devices that allow secret-free access. The identifier can be a MAC address. Specifically: after receiving the probe request frame from the electronic device, the AP can determine whether the MAC address of the electronic device is included in the whitelist. If the MAC address of the electronic device is included in the whitelist, the Wi-Fi configuration information required to access the Wi-Fi network can be carried in a probe response frame and sent to the electronic device. If the MAC address of the electronic device is not included in the whitelist, a probe response frame that does not carry Wi-Fi configuration information is sent.

The identifiers in the above whitelist may be manually added by the user. For example, take the AP as a router as an example. The mobile phone (the mobile phone may be the first device in this application) has the management authority of the router. The mobile phone can configure or control the router, and it can be said that the mobile phone has the management authority to the router. For example, an application for controlling the router can be installed in the mobile phone, and the router can be configured or controlled through the application. For another example, the mobile phone can open the control interface of the router through the webpage, and the router can be configured or controlled in the control interface.

If the user wants to allow the desk lamp to access the Wi-Fi network provided by the router without secret. The user can open the application installed in the mobile phone that can be used to control the router, such as the application of the router, or the smart home application, etc., and use the scan function of the application to scan the QR code of the desk lamp (the QR code contains The MAC address of the lamp), the mobile phone can obtain the MAC address of the lamp. Alternatively, the user can use the application to manually enter the MAC address of the lamp, and the mobile phone can obtain the MAC address of the lamp. Later, when the mobile phone is connected to the Wi-Fi network provided by the router, the mobile phone can send the MAC address of the lamp to the router. After the router receives the MAC address of the lamp, it can save the MAC address of the lamp in the whitelist. In this way, combined with the example in S201, after the desk lamp broadcasts the probe request frame on the channel that can be used for Wi-Fi transmission, the router receives the probe request frame of the desk lamp. The router can determine that the MAC address of the lamp is included in the whitelist. At this time, the router sends a probe response frame containing Wi-Fi configuration information to the lamp.

The identifiers in the above whitelist may also be automatically added by the AP. For example, take the AP as a router as an example. Generally, for an electronic device that has successfully accessed the Wi-Fi network provided by the router, the router can save its MAC address. When the Wi-Fi configuration information of the Wi-Fi network provided by the router is changed, for example, the user changes the SSID of the Wi-Fi network, or changes the access password, usually the user is required to manually re-enter the password before it can be used again. Successfully connected to the Wi-Fi network provided by the router. In this embodiment, the router can automatically add the MAC addresses of electronic devices that have successfully accessed the router into the whitelist before the Wi-Fi configuration information is changed. That is, the whitelist includes the MAC addresses of electronic devices that have successfully accessed the router before the Wi-Fi configuration information is changed. With reference to the example in S201, take the electronic device successfully connected to the router including the mobile phone described in the S201 example before the Wi-Fi configuration information is changed as an example. The router adds the MAC address of the mobile phone to the whitelist. In this way, after the Wi-Fi configuration information is changed, the router can determine that the MAC address of the mobile phone is included in the whitelist after receiving the probe request frame broadcast on the channel available for Wi-Fi transmission by the mobile phone. At this time, the router can send a probe response frame containing Wi-Fi configuration information to the mobile phone.

Take the secret-free access rule including that electronic devices located within a certain distance of the AP allow secret-free access as an example. Specifically: after the AP receives the probe request frame from the electronic device, it can determine whether the distance between the electronic device and the AP is less than or equal to the preset distance. If the distance between the electronic device and the AP is less than or equal to the preset distance, the Wi-Fi configuration information required to access the Wi-Fi network can be carried in a probe response frame and sent to the electronic device. If the distance between the electronic device and the AP is greater than the preset distance, a probe response frame that does not carry Wi-Fi configuration information is sent.

The AP can determine whether the distance between the electronic device and the AP is less than or equal to the preset distance according to the signal strength of the probe request frame sent by the electronic device. For example, when the AP determines that the signal strength of the probe request frame sent by the electronic device is greater than the preset strength, it determines that the distance between the electronic device and the AP is less than or equal to the preset distance, that is, determines that the electronic device is located within a certain distance of the AP. When the AP determines that the signal strength of the probe request frame sent by the electronic device is less than the preset strength, it determines that the distance between the electronic device and the AP is greater than the preset distance, that is, it determines that the electronic device is not located within a certain distance range of the AP.

Take the secret-free access rule including allowing the secret-free access of electronic devices within a certain period of time as an example. Among them, the specific time period can be predefined, such as a certain time period every day (such as 6 pm to 7 pm). Take the specific time period from 6 pm to 7 pm as an example. After receiving the probe request frame from the electronic device, the AP can determine whether the time when the probe request frame is received is included in the specific time period, that is, whether it is a probe request frame received between 6 pm and 7 pm. If the probe request frame is received between 6 pm and 7 pm, the Wi-Fi configuration information required to access the Wi-Fi network can be carried in the probe response frame and sent to the electronic device. If it is not the probe request frame received between 6 pm and 7 pm, the probe response frame without Wi-Fi configuration information is sent.

The specific time period may also be a time period triggered by the user to start timing, and the duration is equal to the preset duration. If there is a button in the AP, it is used to trigger the device's secret-free access. The AP starts timing after receiving the user's operation on the button, and allows the device to gain secret-free access within a preset period of time. That is to say, if the AP receives the probe request frame from the electronic device within the preset time period after receiving the user's operation on the button, it sends the probe response frame carrying the Wi-Fi configuration information to the electronic device. Alternatively, the user can set the time period for secret-free access in the management interface of the AP, or trigger the device to allow secret-free access and start timing.

The above description is based on an example in which the secret-free access rule set on the AP side includes a rule. In some other embodiments, when the secret-free access rules set on the AP side include multiple rules in the foregoing rules, the AP may send a portable packet to the electronic device when it determines that one of the rules is satisfied or when it is determined that these multiple rules are satisfied at the same time. Probe response frame of Wi-Fi configuration information. For example, the secret-free access rules set on the AP side include: electronic devices located within a certain distance of the AP allow secret-free access, and allow electronic devices to be secret-free access within a specific time period as an example. In some embodiments, after the AP receives the probe request frame from the electronic device, it may be included when determining that the distance between the electronic device and the AP is less than or equal to a preset distance, or when determining that the probe request frame is received Within a specific time period, send a probe response frame carrying Wi-Fi configuration information to the electronic device. In some other embodiments, after the AP receives the probe request frame from the electronic device, it may determine that the distance between the electronic device and the AP is less than or equal to the preset distance, and when it determines that the probe request frame is received, it includes In a specific time period, a probe response frame carrying Wi-Fi configuration information is sent to the electronic device. If it is determined that the distance between the electronic device and the AP is less than or equal to the preset distance, but the time when the probe request frame is received is not included in the specific time period, or it is determined that the time when the probe request frame is received is included in the specific time period , But the distance between the electronic device and the AP is greater than the preset distance, a probe response frame that does not carry Wi-Fi configuration information is sent to the electronic device.

In the embodiment of the present application, as an example, a new field can be extended in the probe response frame to carry Wi-Fi configuration information. For example, a new field can be extended in the reserved field of the probe response frame to carry Wi-Fi configuration information. Among them, the field carrying Wi-Fi configuration information in the probe response frame may be predefined.

For example, please refer to FIG. 5, which shows a schematic diagram of an example of the frame structure of a Wi-Fi frame provided by the present application. As shown in FIG. 5, the Wi-Fi frame 500 may include: a frame header (ie, a MAC header) 501, a frame body (frame body) 502, and a frame check sequence (FCS) field 503. Wherein, the above-mentioned MAC header 501 is a media access control (media access control, MAC) header.

The frame control field 5011 may include a protocol version field (protocol version) 501a, a type field 501b, and so on. The protocol version field 501a is used to indicate the protocol version followed by the Wi-Fi frame 500, and the protocol version is usually 0. The type field 501b may include Type and Subtype. Type is used to indicate whether the corresponding frame is a management frame, a data frame, or a control frame. Subtype is used to indicate the subtype of the frame. For example, when Type=00, it can indicate that the corresponding frame is a management frame. At this time, the Subtype can indicate which of the management frames is a Beacon frame, a probe request frame, or a probe response frame. For example, when Type = 00 and Subtype = 0100, the Wi-Fi frame 500 shown in Figure 5 is a probe request frame; when Type = 00 and Subtype = 0101, the Wi-Fi frame 500 shown in Figure 5 is a probe response frame. The address field 5013 may include address information such as a source address, a destination address, a transmitting workstation address, and a receiving workstation address.

As shown in FIG. 5, the frame entity 502 includes an SSID field 5021, a supported rate (supported Rates) 5022, an extended supported rate (extended supported rates) 5023, a reserved field 5024, and so on. Among them, the supported rate 5022 and the extended supported rate 5023 are used to indicate the set of rates supported by the electronic device or AP.

In this embodiment, when the Wi-Fi frame 500 shown in FIG. 5 is a probe response frame, that is, when the Type and Subtype in the type field 501b indicate that the Wi-Fi frame 500 is a probe response frame, the frame entity 502 can carry The Wi-Fi configuration information of the Wi-Fi network provided by the AP. For example, the reserved field 5024 of the frame entity 502 can be used to carry Wi-Fi configuration information.

Among them, the specific composition and corresponding description of the Wi-Fi configuration information carried in the probe response frame are shown in Table 1.

Table 1

As shown in Table 1, the field used to indicate Wi-Fi configuration information in the probe response frame includes three parts: type, length, and value. The content of the type (type) may be 0x51, which is used to indicate the attribute type of the field, that is, it is used to indicate that the field is Wi-Fi configuration information. The length of the type can be 1 byte. Of course, the type can also be other content, and the specific content can be predefined or negotiated between the electronic device and the AP. The content of length can be 0x08, which is used to indicate the length of value. The length of the type can be 1 byte. The content of the length is determined by the length of the value, and is not limited to 0x08, and can also be other content. The content of the value is specifically determined by the Wi-Fi configuration information of the Wi-Fi network provided by the AP.

It should be noted that, in some embodiments of the present application, the Wi-Fi configuration information carried in the probe response frame of the AP may be encrypted. The encryption key used to encrypt the Wi-Fi configuration information can be pre-configured in the AP and the electronic device. The encryption keys of different electronic devices may be the same or different, and the embodiment of the present application does not make specific restrictions here.

S204. The electronic device receives a probe response frame from the AP, and the Wi-Fi configuration information carried in the probe response frame is used for the electronic device to access the Wi-Fi network provided by the AP.

Wherein, after receiving the probe response frame from the AP, the electronic device parses the probe response frame. If the electronic device determines that the probe response frame contains a field for carrying Wi-Fi configuration information, it indicates that the AP is guiding itself to access.

In some embodiments, when the electronic device is not currently connected to another Wi-Fi network, the electronic device may send a connection request to the AP, and the connection request includes the Wi-Fi configuration information. After receiving the connection request, the AP authenticates the Wi-Fi configuration information in the connection request. After the authentication is passed, the electronic device is allowed to access. At this time, the electronic device accesses the Wi-Fi network provided by the AP. For example, combining the examples in S201 and S203 above, the desk lamp can receive the probe response frame carrying Wi-Fi configuration information from the AP, and the desk lamp can send a connection request containing the Wi-Fi configuration information to the AP at this time. After the AP authenticates the Wi-Fi configuration information in the received connection request, it agrees to access the desk lamp. At this time, the desk lamp can successfully access the Wi-Fi network provided by the AP.

In some other embodiments, when the electronic device is currently connected to another Wi-Fi network, the electronic device can disconnect from the Wi-Fi network, and then send the Wi-Fi configuration information to the AP. Connection request in order to access the Wi-Fi network provided by the AP. Or, if the electronic device is an electronic device with a display screen (such as a mobile phone), as shown in FIG. 6, the electronic device may display prompt information 601 for prompting the user that there is currently an AP to guide access, and asking the user whether to agree to access. If the user agrees to access, the electronic device can disconnect from the current Wi-Fi network, and then send a connection request carrying the Wi-Fi configuration information to the AP, so as to access the Wi-Fi network provided by the AP. If the user does not agree to access, the electronic device can save the Wi-Fi configuration information. Later, when the user chooses to access the Wi-Fi network, the electronic device can use the stored Wi-Fi configuration information to access the Wi-Fi network provided by the AP without the user having to manually enter the access password.

It should be noted that if the Wi-Fi configuration information in the probe response frame is encrypted, the electronic device can use the preset encryption key pair after determining that the probe response frame contains a field for carrying Wi-Fi configuration information This field is parsed to obtain Wi-Fi configuration information.

After the AP detects the probe request frame, it can reply to the electronic device a probe response frame carrying Wi-Fi configuration information of the Wi-Fi network provided by the AP. The electronic device can access the Wi-Fi network provided by the AP according to the Wi-Fi configuration information in the probe response frame. In this way, the user does not need to manually enter the access password, and only needs to receive a probe response frame to obtain the Wi-Fi configuration information required to access the Wi-Fi network to complete the access, which improves the access of the electronic device to the Wi-Fi network.
