Wi-Fi connection method and device

The present application claims priority of a chinese patent application entitled "a method for AP to actively direct STA Wi-Fi privacy-free access" filed by the national intellectual property office at 16/09/2019 with application number 201910872247.5, the entire contents of which are incorporated herein by reference.

Technical Field

The present application relates to the field of communications, and in particular, to a wireless fidelity (Wi-Fi) connection method and apparatus.

Background

Wi-Fi technology is a wireless local area network technology that the Wi-Fi alliance has been established in the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard. Two types of devices, Access Point (AP) and Station (STA), are typically involved in Wi-Fi technology. The AP may also be referred to as a wireless access point, and is a provider of a Wi-Fi network, and allows other wireless devices to access the AP and provides data access for the accessed devices. Devices accessing a Wi-Fi network may be referred to as STAs. For example, electronic devices such as mobile phones, tablet computers, and notebook computers that support Wi-Fi functions can be used as STAs.

Currently, the process of an STA (for example, taking the STA as a mobile phone) accessing a Wi-Fi network provided by an AP is as follows: the user selects a Wi-Fi network which the mobile phone wants to access on the mobile phone. For example, the user may select a Service Set Identifier (SSID) of a Wi-Fi network that the mobile phone is desired to access in the wireless lan setup interface of the mobile phone. And responding to the selection of the user, and displaying a password input interface by the mobile phone for the user to input the access password of the Wi-Fi network. After the user inputs the access password, the mobile phone can carry the Wi-Fi configuration information in the connection request and transmit the Wi-Fi configuration information to the AP providing the Wi-Fi network. The Wi-Fi configuration information at least comprises an access password input by a user and an SSID of the Wi-Fi network. And 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 is not passed, the access of the mobile phone is refused.

It is understood that, in the above process, the manual input of the access password by the user is a precondition for the STA to access the Wi-Fi network, and this affects the speed of the STA accessing the Wi-Fi network.

Detailed Description

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present embodiment, "a plurality" means two or more unless otherwise specified.

At present, electronic equipment such as a mobile phone and the like supporting Wi-Fi functions can be used as an STA to access a Wi-Fi network provided by an AP to realize data access. To ensure the security of the network connection, the Wi-Fi network provided by the AP is typically encrypted. That is, before an electronic device serving as an STA accesses a Wi-Fi network provided by an AP, the AP needs to authenticate Wi-Fi configuration information carried in a connection request sent by the electronic device. If the authentication is passed, the electronic equipment is approved to be accessed, otherwise, the electronic equipment is refused to be accessed. Wherein the Wi-Fi configuration information at least comprises: SSID and access password of Wi-Fi network. The Wi-Fi configuration information may also include an encryption of the Wi-Fi network.

For electronic devices with a display screen, such as mobile phones and tablet computers, the access password can be manually input by the user. And manually entering the access password may affect the speed at which the electronic device accesses the Wi-Fi network. In addition, with the progress of science and technology, the number of smart home devices supporting the Wi-Fi function is increased. Some smart home devices, such as a desk lamp, a sound box, an air conditioner, etc., do not have a display screen, that is, they cannot provide a password input interface for a user to input an access password. Therefore, if the user can avoid inputting the access password on the electronic equipment side serving as the STA, the speed of accessing the electronic equipment to the Wi-Fi network can be improved, and the possibility of accessing the electronic equipment without a display screen to the Wi-Fi network is provided.

The prior art provides a solution for avoiding user input of an access password on the side of an electronic device acting as an STA. Taking the electronic device as an example, the specific process is as follows: first, the user presses a factory reset button of the desk lamp. In response to the user's operation of the button, the desk lamp performs broadcasting of a Wi-Fi beacon (beacon) frame. When the AP works, all channels which can be used by Wi-Fi transmission can be monitored, so that the AP can receive Wi-Fi beacon frames broadcasted by the desk lamp. And then, a prompting lamp corresponding to the AP can flash to prompt the user that equipment needs to be accessed. The user may operate a corresponding button provided on the AP to indicate consent to access the device. In response to the operation of the user on the corresponding button on the AP, the AP encrypts the Wi-Fi configuration information (including, for example, SSID, access password, and encryption scheme) of the Wi-Fi network provided by the AP, and then stores the encrypted Wi-Fi configuration information in the last two bytes of a destination Internet Protocol (IP) address of a plurality of multicast packets (at least several tens of multicast packets are required), and transmits the plurality of multicast packets. The encryption key is configured in advance in the AP and the desk lamp. And after receiving the multicast packets, the desk lamp splices the multicast packets and adopts a preset encryption key to analyze so as to obtain the Wi-Fi configuration information. And finally, the desk lamp sends a connection request of the carried Wi-Fi configuration information to the AP. And after receiving the connection request, the AP authenticates the Wi-Fi configuration information. And after the authentication is passed, the desk lamp is approved to be accessed. Therefore, the desk lamp is successfully accessed to the Wi-Fi network provided by the AP.

It can be seen that, in the scheme of the prior art, which avoids the user from inputting the access password, the electronic device serving as the STA needs to receive and splice a plurality of multicast packets before obtaining the corresponding Wi-Fi configuration information, which still cannot enable the electronic device to access the Wi-Fi network quickly. In addition, the access process requires the user to perform multiple operations, which results in poor user experience.

The embodiment of the application provides a Wi-Fi connection method, and after a Wi-Fi function of electronic equipment is started, the electronic equipment can broadcast a probe request (probe request) frame so as to scan which available APs are around. After monitoring the probe response frame, the AP may reply to the electronic device with a probe response (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. Therefore, the Wi-Fi configuration information required by accessing the Wi-Fi network can be obtained by receiving a probe response frame without manually inputting an access password by a user, so that the access is completed, and the speed of accessing the electronic equipment to the Wi-Fi network is improved. In addition, the user does not need to perform multiple operations, and the operation experience of the user is improved.

For example, the electronic device described in the embodiments of the present application may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a Personal Digital Assistant (PDA), a smart home device such as a desk lamp, a sound box, an air conditioner, an electric cooker, a television, an Augmented Reality (AR) \ Virtual Reality (VR) device, or other devices that support Wi-Fi functions. In the embodiment of the present application, the AP may be a router. The AP may also be an electronic device such as a cellular phone that has AP capabilities (e.g., is capable of providing a Wi-Fi network), i.e., the AP-capable electronic device may act as an AP. The embodiment of the application does not specially limit the specific forms of the AP and the electronic device accessing the Wi-Fi network provided by the AP as the STA.

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

Fig. 2 is a schematic flowchart of a Wi-Fi connection method according to an embodiment of the present disclosure. As shown in fig. 2, the method may include:

s201, after the Wi-Fi function of the electronic equipment is started, the electronic equipment sends a probe request frame.

After the Wi-Fi function of the electronic equipment is started, the electronic equipment can broadcast a probe request frame on a channel which can be used by Wi-Fi transmission so as to scan available APs around.

In some embodiments, the electronic device may turn on Wi-Fi functionality of the electronic device after receiving the first operation by the user. The first operation is an operation of turning on a Wi-Fi function of the electronic device by a user. Illustratively, the first operation may be an operation of a button of the electronic device for turning on the Wi-Fi function by the user. The button may be a virtual key displayed on a display screen of the electronic device or a physical key provided in the electronic device.

For example, the electronic device is a device having a display screen, such as a mobile phone, and the first operation is an operation of a virtual key 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 a switch button 302 of the wireless lan in a 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 started, the mobile phone can broadcast a probe request frame on a channel which can be used by Wi-Fi transmission so as to scan available APs around.

For another example, the electronic device is a device without a display screen, such as a desk lamp, and the first operation is an operation on a physical key provided in the desk lamp, such as a factory reset button. As shown in fig. 4, the user may operate a factory reset button 401 of the desk lamp. In response to the operation, the desk lamp may turn on a Wi-Fi function of the desk lamp. After the Wi-Fi function of the desk lamp is turned on, the desk lamp can broadcast a probe request frame on a channel which can be used by Wi-Fi transmission so as to scan available APs around.

S202, the AP receives a probe request frame from the electronic equipment.

When the AP works, all channels which can be used by Wi-Fi transmission are monitored. Thus, after the electronic device broadcasts a probe request frame on a channel usable by Wi-Fi transmissions, the AP may receive a proberequest frame from the electronic device. In connection with the example in S201, for example, the AP may receive a probe request frame from the handset. As another example, the AP may receive a probe request frame from the desk lamp.

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

The Wi-Fi configuration information is used for the electronic equipment to access a Wi-Fi network provided by the AP. The Wi-Fi configuration information includes at least: SSID and access password of Wi-Fi network. The Wi-Fi configuration information may also include an encryption of the Wi-Fi network.

In some embodiments, after receiving a probe request frame from an electronic device, an AP may carry Wi-Fi configuration information of a Wi-Fi network provided by the AP in a probe response frame and send the Wi-Fi configuration information to the electronic device.

In some other embodiments, after receiving the probe request frame from the electronic device, the AP may send the electronic device with the Wi-Fi configuration information of the Wi-Fi network provided by the AP in a probe response frame when determining that the lock-exempt access rule is met. That is, the AP side may be provided with a tight attach exemption rule. After receiving the probe request frame from the electronic equipment, if the AP determines that the electronic equipment conforms to the exempt seal access rule, the AP indicates that the electronic equipment is allowed to exempt seal access, namely, the AP avoids the user from inputting a password. At this time, the AP may carry Wi-Fi configuration information required for accessing the Wi-Fi network in a cyberseponse frame and transmit the Wi-Fi configuration information to the electronic device.

Illustratively, the AP-side set tight-access-free rule may include one or more of the following: electronic equipment in the white list allows secret-free access, electronic equipment located within a certain distance range of the AP allows secret-free access, electronic equipment allows secret-free access within a specific time period, and the like.

For example, the secret-exempt access rule includes that the electronic device in the white list allows secret-exempt access. The white list may include an identification of one or more electronic devices that allow privacy-free access. The identification may be a MAC address. Specifically, the method comprises the following steps: after receiving the probe request frame from the electronic device, the AP may determine whether the MAC address of the electronic device is included in the white list. If the MAC address of the electronic equipment is contained in the white list, the Wi-Fi configuration information required by accessing the Wi-Fi network can be carried in a probe response frame and sent to the electronic equipment. And if the MAC address of the electronic equipment is not contained in the white list, sending a probe response frame which does not carry the Wi-Fi configuration information.

The identifiers in the white list may be manually entered by the user. For example, the AP is a router. The handset (which may be the first device in this application) has administrative rights to the router. The handset may configure or control the router may be referred to as the handset having administrative privileges for the router. For example, an application for controlling the router may be installed in a handset, through which the router may be configured or controlled. For another example, the mobile phone may open a control interface of the router through a web page, and the router may be configured or controlled in the control interface.

If the user wants to allow the desk lamp to be prevented from being tightly connected with the Wi-Fi network provided by the router. The user can open an application installed in the mobile phone and used for controlling the router, such as the application of the router, or an intelligent home application, and the like, and the mobile phone can obtain the MAC address of the desk lamp by scanning the two-dimensional code of the desk lamp (the two-dimensional code contains the MAC address of the desk lamp) by using the scanning function of the application. Or, the user can manually input the MAC address of the desk lamp by using the application, and at this time, the mobile phone can obtain the MAC address of the desk lamp. Then, under the condition that the mobile phone accesses the Wi-Fi network provided by the router, the mobile phone can send the MAC address of the desk lamp to the router. After the router receives the MAC address of the desk lamp, the MAC address of the desk lamp can be stored in a white list. Thus, with reference to the example in S201, after the desk lamp broadcasts the probe request frame on the channel available for Wi-Fi transmission, the router receives the probe request frame of the desk lamp. The router may determine that the MAC address of the desk lamp is included in the white list, at which point the router sends a probe response frame including the Wi-Fi configuration information to the desk lamp.

The identifier in the white list may be automatically added by the AP. For example, the AP is a router. Generally, a router may maintain its MAC address for electronic devices that successfully access a Wi-Fi network provided by the router. When the Wi-Fi configuration information of the Wi-Fi network provided by the router changes, for example, the user modifies the SSID of the Wi-Fi network or modifies the access password, the user is usually required to manually input the password again to successfully access the Wi-Fi network provided by the router again. In this embodiment, the router may automatically add the MAC address of the electronic device that has successfully accessed the router to the white list before the Wi-Fi configuration information is changed. That is, the white list includes the MAC address of the electronic device that has successfully accessed the router before the Wi-Fi configuration information is changed. With reference to the example in S201, before the Wi-Fi configuration information is changed, the electronic device that has successfully accessed the router includes the mobile phone described in the example in S201. The router adds the MAC address of the mobile phone into a white list. Thus, after the Wi-Fi configuration information is changed, the router can determine that the MAC address of the mobile phone is contained in the white list after receiving the probe request frame broadcast by the mobile phone on the channel available for Wi-Fi transmission. At this point, the router may send a probeseponse frame containing Wi-Fi configuration information to the handset.

For example, the secret access prevention rule includes that the electronic device located within a certain distance range of the AP allows secret access prevention. Specifically, the method comprises the following steps: after receiving the probe request frame from the electronic device, the AP may determine whether a distance between the electronic device and the AP is less than or equal to a preset distance. If the distance between the electronic equipment and the AP is smaller than or equal to the preset distance, carrying Wi-Fi configuration information required by accessing the Wi-Fi network in a probe response frame and sending the Wi-Fi configuration information to the electronic equipment. And if the distance between the electronic equipment and the AP is greater than the preset distance, sending a properesponse frame which does not carry the Wi-Fi configuration information.

The AP may determine whether a distance between the electronic device and the AP is less than or equal to a 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, it determines that the electronic device is located within a certain distance range of the AP. When the AP determines that the signal intensity of the probe request frame sent by the electronic equipment is smaller than the preset intensity, the distance between the electronic equipment and the AP is determined to be larger than the preset distance, namely the electronic equipment is determined not to be located within a certain distance range of the AP.

For example, the privacy exemption rule includes allowing the electronic device to be privacy exempted from accessing within a specific time period. Wherein the specific time period may be predefined, such as a certain time period of each day (e.g., six pm to seven pm). Take the specific time period from six pm to seven pm as an example. After receiving the probe request frame from the electronic device, the AP may determine whether the time when the probe request frame is received is included in the specific time period, that is, whether the received probe request frame is from six pm to seven pm. If the received probe request frame is from six pm to seven pm, the Wi-Fi configuration information required for accessing the Wi-Fi network can be carried in the probe response frame and sent to the electronic equipment. And if the received probe request frame is not the probe request frame from six pm to seven pm, sending a probe response frame which does not carry the Wi-Fi configuration information.

The specific time period may also be a time period triggered by the user to start timing, and the time period is equal to the preset time period. If the AP is provided with a key for triggering the device to be allowed to be free from secret access, the AP starts timing after receiving the operation of the key by the user, and the device is allowed to be free from secret access within the preset time length. That is to say, within the preset time length after receiving the operation of the key by the user, if a probe request frame from the electronic device is received, the AP sends a probe response frame carrying the Wi-Fi configuration information to the electronic device. Alternatively, the user may set a time period for the privacy-free access in the management interface of the AP, or trigger the permission of the device for privacy-free access and start timing.

The above description has been given by taking an example in which the close-avoidance rule set on the AP side includes one rule. In some other embodiments, when the close-access-free rule set on the AP side includes multiple rules in the above rules, the AP may send a cyberseponse frame carrying Wi-Fi configuration information to the electronic device when determining that one of the rules is satisfied or when determining that the multiple rules are satisfied at the same time. For example, the tight attach exemption rule set on the AP side includes: electronic devices located within a certain distance of the AP allow for privacy-free access, and electronic devices are allowed to access within a certain time period. In some embodiments, after receiving a probe request frame from an electronic device, an AP may send a probe response frame carrying Wi-Fi configuration information to the electronic device when determining that a distance between the electronic device and the AP is less than or equal to a preset distance, or when determining that a time when the probe request frame is received is included within a specific time period. In some other embodiments, after receiving a probe request frame from an electronic device, an AP may send a probe response frame carrying Wi-Fi configuration information to the electronic device when determining that a distance between the electronic device and the AP is less than or equal to a preset distance and when determining that a time when the probe request frame is received is included in a specific time period. And if the distance between the electronic equipment and the AP is determined to be smaller than or equal to the preset distance, but the time of receiving the probe request frame is not included in the specific time period, or the time of receiving the probe request frame is determined to be included in the specific time period, but the distance between the electronic equipment and the AP is greater than the preset distance, sending a probe response frame which does not carry the Wi-Fi configuration information to the electronic equipment.

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

For example, please refer to fig. 5, which shows an example of a frame structure of a Wi-Fi frame provided in the present application. As shown in fig. 5, a Wi-Fi frame 500 may include: a frame header (i.e., MAC header) 501, a frame entity (frame body)502, and a Frame Check Sequence (FCS) field 503. The MAC header 501 is a Media Access Control (MAC) header.

As shown in fig. 5, the MAC header 501 may include a frame Control field (frame Control)5011, a duration/identification (duration/ID)5012, an address field (address)5013, a sequence Control field (sequence Control)5014, and the like.

The frame control field 5011 may include a protocol version field (protocol version)501a, a type field 501b, and the like. The protocol version field 501a is used to indicate the protocol version, typically 0, to which the Wi-Fi frame 500 conforms. The Type field 501b may include Type and Subtype. The Type is used to indicate that 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 is 00, the corresponding frame may be indicated as a management frame. At this time, the Subtype may indicate which of the Beacon frame, the probe request frame, or the probe response frame the management frame is. For example, when Type is 00 and Subtype is 0100, the Wi-Fi frame 500 shown in fig. 5 is a probe request frame; when Type is 00 and Subtype is 0101, the Wi-Fi frame 500 shown in fig. 5 is a probe response frame. The address field 5013 may include address information such as source address, destination address, transmitting station address, receiving station address, etc.

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

In this embodiment, when the Wi-Fi frame 500 shown in fig. 5 is a probe response frame, i.e. 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 may carry Wi-Fi configuration information of the Wi-Fi network provided by the AP. For example, the reserved field 5024 of the frame entity 502 may be used to carry Wi-Fi configuration information.

The specific composition and the 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 for indicating the Wi-Fi configuration information in the probe response frame includes three parts, which are: type (type), length (length), and value (value). Therein, the content of type (type) may be 0x51, which is used to indicate the attribute type of the field, i.e. to indicate that the field is Wi-Fi configuration information. The type may be 1 byte in length. Of course, the type may be other content, and the specific content may be predefined or negotiated between the electronic device and the AP. The content of the length (length) may be 0x08 for indicating the length of value. The type may be 1 byte in length. The content of the length is determined by the length of value, and is not limited to 0x08, and may be other content. The content of the value (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 by the AP in the probe response frame may be encrypted. An encryption key for encrypting the Wi-Fi configuration information may be pre-configured in the AP and the electronic device. The encryption keys of different electronic devices may be the same or different, and embodiments of the present application are not limited in this respect.

S204, the electronic equipment 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 equipment to access a Wi-Fi network provided by the AP.

The electronic device analyzes the probe response frame after receiving the probe response frame from the AP. If the electronic equipment determines that the probe response frame contains a field for carrying Wi-Fi configuration information, the AP is indicated to be guided to access.

In some embodiments, the electronic device may send a connection request to the AP, including the Wi-Fi configuration information, in the event that the electronic device is not currently accessing other Wi-Fi networks. And after receiving the connection request, the AP authenticates the Wi-Fi configuration information in the connection request. And after the authentication is passed, the electronic equipment is granted access, and at the moment, the electronic equipment is accessed to the Wi-Fi network provided by the AP. For example, in connection with the examples in S201 and S203 described above, the desk lamp may receive a probe response frame carrying Wi-Fi configuration information from the AP, and at this time, the desk lamp may send a connection request including the Wi-Fi configuration information to the AP. And after the authentication of the Wi-Fi configuration information in the received connection request is passed, the AP agrees to access the desk lamp, and at the moment, the desk lamp can successfully access the Wi-Fi network provided by the AP.

In some other embodiments, in the case that the electronic device has currently accessed other Wi-Fi networks, the electronic device may disconnect from the Wi-Fi network and then send a connection request carrying the Wi-Fi configuration information to the AP in order to access the Wi-Fi network provided by the AP. Alternatively, if the electronic device is an electronic device (e.g. a mobile phone) with a display screen, as shown in fig. 6, the electronic device may display a prompt message 601 for prompting the user that an AP is currently available to guide access and asking the user whether to grant 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 may save the Wi-Fi configuration information. And when the user selects to access the Wi-Fi network, the electronic equipment can access the Wi-Fi network provided by the AP by using the saved Wi-Fi configuration information without manually inputting an access password by the user.

It should be noted that, if the Wi-Fi configuration information in the probe response frame is encrypted, after determining that the probe response frame includes a field for carrying the Wi-Fi configuration information, the electronic device may analyze the field by using a preset encryption key to obtain the Wi-Fi configuration information.

According to the Wi-Fi connection method provided by the embodiment of the application, after the Wi-Fi function of the electronic equipment is started, the electronic equipment can broadcast the probe request frame so as to scan available APs around. After monitoring the probe request frame, the AP may reply to the electronic device with a probe response frame carrying Wi-Fi configuration information of a Wi-Fi network provided by the AP. The electronic equipment can access the Wi-Fi network provided by the AP according to the Wi-Fi configuration information in the probe response frame. Therefore, the Wi-Fi configuration information required by accessing the Wi-Fi network can be obtained by receiving a probe response frame without manually inputting an access password by a user, so that the access is completed, and the speed of accessing the electronic equipment to the Wi-Fi network is improved. The user does not need to perform multiple operations, and the operation experience of the user is improved.

In addition, after receiving the probe request frame of the electronic equipment, the AP may reply the probe response frame carrying the Wi-Fi configuration information to the electronic equipment after determining that the set privacy-exempt access rule is satisfied, so that security of privacy-exempt access can be ensured. The Wi-Fi configuration information is carried in the probe response frame, so that the AP is in the dominant position of access, the device is guided to be automatically accessed in a secret-free mode, and the usability is improved. For the intelligent home equipment, the MAC address of the intelligent home equipment can be added into the secret-access-free white list, so that the Wi-Fi can be always online through one-time operation of a user, and the use experience of the user is improved.
