Description

 Method and corresponding device for sending and obtaining wifi networking information  

The present invention relates to the field of computer application technologies, and in particular, to a method and a corresponding device for transmitting and acquiring wifi networking information.

With the rise of smart hardware, more and more smart devices have entered people's lives. For wifi-type smart devices (smart devices with built-in wifi modules, this smart device can access the network via wifi module), how to Getting it to the network is a challenge.

Since WiFi-type smart devices such as smart air conditioners, smart humidifiers, and smart weight scales do not have screens like PCs, mobile phones, and tablets, it is impossible to complete network access by manually discovering wireless routers and entering passwords. That is to say, a large part of the wifi-type smart device can scan to the surrounding wireless router, but can not let the user perceive what it "sees", and the user cannot directly use the manual dialogue mode (for example, by keyboard or touch). The screen enters the wireless router's service set ID and password) to allow the wifi-type smart device to access the network.

In order to solve the above problems, there are currently several implementation methods in the industry:

The first way: the mobile phone sends a data packet to the router through UDP (User Data Packet Protocol), and the router forwards the data packet. Since the amount of information that a data packet can carry is small, a package can only carry a maximum of one byte of information. Therefore, it is necessary to transmit a set of data packets, and the wifi networking information is transmitted by the regular change of the packet length. The wifi-type smart device parses a set of data packets, and obtains wifi networking information to access the network.

In this way, the number of data packets to be sent is large, resulting in long transmission time. The wifi-type smart device takes too long to obtain the wifi networking information. In addition, in order to prevent the packet loss from being required, the technical requirements are complicated.

The second way: the mobile phone sends a multicast data packet to the router via UDP, and the router forwards the multicast data packet. The wifi-type smart device parses the multicast data packet, and obtains the wifi networking information to access the network. However, the multicast compatibility problem is more prominent in this way. Some routers may not be forwarded when the specific option is enabled (for example, IGMP Snooping), which may cause the wifi-type smart device to be unable to access for a long time. network.

The present invention will be described in detail below with reference to the drawings and specific embodiments.

The core idea of the present invention is that a management frame carrying the wifi networking information is constructed by the first wifi-type smart device, and the management frame is sent for the second wifi-type smart device to monitor and parse the wifi networking information from the management frame. The management frame may be, but not limited to, a probe request frame, a probe response frame, an association request frame, a reassociation request frame, an action frame, or a beacon. frame.

1 is a schematic structural diagram of a system on which an embodiment of the present invention is based, wherein the first wifi-type smart device may be a smart device including a smart device, a tablet computer, a notebook, and the like, and having an input device, wherein the input device may include a touch Control screens, keyboards, tablets, etc. These input devices can easily input wifi networking information such as SSID and password. The second wifi type smart device may be a smart home device such as a smart air conditioner, a smart humidifier, a smart weight scale, a smart washing machine, or a smart office device such as a wifi type printer, and the second wifi type smart device usually includes The wifi module may not include input devices such as a touch screen, a keyboard, a tablet, and the like.

In the following embodiments, the smart phone is used as the first wifi type smart device and the smart home device is taken as the second wifi type smart device as an example.

FIG. 2 is a flowchart of a first method according to an embodiment of the present invention. As shown in FIG. 2, the method may include: in 201, a smart home device enters a listening state.

The wifi module of the wifi smart home device usually has two modes, one is a monitor mode and the other is a station mode. Among them, the monitor mode is mainly used to monitor data packets in the wireless network, and the station mode is a working mode after the wifi device is connected to the network (connected to the router). When the smart home device enters the monitor mode, it enters the listening state. In the embodiment of the present invention, the smart home device may be preset to be in a listening state, or may be manually switched to a listening state by a user.

In 202, the smart phone generates a management frame carrying wifi networking information, wherein the wifi networking information includes a feature code, an SSID of the target router, and a password.

The management frame in this step may be a probe request frame, a probe response frame, an action frame, or a beacon frame.

The feature code, the SSID and the password of the target router in the management frame may be carried in a pre-agreed format, wherein the feature code is used to represent that the management frame carries the wifi networking information, and the SSID and password of the target network are used for the smart terminal device. Connect to a wireless router to access the target network.

As an example, for example, a feature code, an SSID, and a password are carried in a management frame in a manner of continuously storing 50 bytes. The feature code assumes the "APCP" identifier agreed by both parties, which occupies 4 bytes, and the remaining 46 bytes are used to carry the SSID and password.

In addition, the wifi networking information may include at least one of verification information, encryption information, and router authentication information in addition to the feature code, the SSID, and the password. The verification information is used for verifying the wifi networking information, and the encryption information is used to indicate the encryption method. For example, encryption methods such as DES (Data Encryption Standard) and IDEA (International Data Encryption Algorithm) can be used, and the router authentication information can be used for Indicates the type of authentication that needs to be performed when accessing the network. For example, WEP (Wired Equivalent Privacy), WPA (Wi-Fi Network Protected Access), WPA2, etc. can be used.

As another example, for example, a feature code, an SSID, a password, and a check information are carried in a management frame in a manner of continuously storing 50 bytes. The feature code assumes the APCP identifier, which occupies 4 bytes, the last 2 bytes are used to carry the check code, and the remaining 44 bytes are used to carry the SSID and password. The way other information is carried is similar to this, no longer an example.

In order to ensure security, the SSID and password in the wifi networking information can be encrypted, and the pre-agreed encryption method can be used, or the encryption method indicated by the encrypted information carried by the wifi networking information can be used.

In 203, the calling wifi direct interface sends a management frame carrying the wifi networking information.

The smart phone can transmit the management frame by calling the wifi direct interface. At present, most smart phones can support the wifi direct technology, and the smart phone can directly transmit the management frame by calling the wifi direct interface. For example, in the iOS platform, Apple released a MultipeerConnectivity.framework framework after iOS 7.0, which mainly solves the problem of peer-to-peer communication between iOS devices without internet. In this case, the solution can use the API of the publishing service (MCNearbyServiceAdvertiser or MCAdvertiserAssistant) in the framework to send management frames carrying wifi networking information.

If it is a self-developed smart phone, it is also possible to customize the interface during development and to manage the frame transmission via a customized interface.

The above steps 202 and 203 may be performed under the trigger of the user. For example, the user inputs the SSID and the password on the smart phone or selects the scanned SSID and inputs the password, and then triggers the smart phone to execute the above 202 and 203 by clicking a function button or the like.

In addition, the above step 201 may also be performed after 202 and 203, or may be performed simultaneously with 202 and 203. For example, the user can switch the smart home device to the listening state at the same time or after sending the management frame carrying the wifi networking information through the smart phone.

It should be noted that, in the embodiment of the present invention, the management frame sent by the smart phone does not need to be directly sent to the wifi-type smart device in the listening state by using the wifi direct technology.

In 204, the smart home device parses the monitored management frame to obtain wifi networking information.

In this step, the feature code information may be set in the smart home device in advance, and the smart home device first determines whether the feature code included in the monitored management frame is consistent with the preset feature code information, and filters out the inconsistent management frame. For a consistent management frame, the SSID and password are parsed from the management frame according to the pre-agreed wifi networking information format.

For example, in the smart home device, the APCP is preset as the feature code information, and the content included in the received management frame is compared with the APCP to determine whether the APCP is included. If not, it is determined that the management frame does not include the wifi networking information; Including APCP, it is determined that the management frame contains wifi networking information, and can be parsed according to a pre-agreed wifi networking information format, for example, obtaining the SSID and password from the next 44 bytes of the signature information, and using the next The check code of the 2 bytes is checked.

In addition, if the SSID and the password are encrypted, the smart home device can decrypt using the pre-agreed encryption method or the encryption method indicated by the encrypted information obtained from the wifi networking information to obtain the decrypted SSID and password.

With this parsing method, the wifi networking information can be carried without being restricted to the interface of the call, and is not limited to the specific type of management frame used.

In 205, the smart home device utilizes the acquired wifi networked information access network.

The smart home device connects to the wireless router by using the parsed SSID and password to access the network, and can further use the router authentication information parsed from the wifi networking information to send an authentication request to the accessed wireless router.

FIG. 3 is a flowchart of a second method according to an embodiment of the present invention. As shown in FIG. 3, the method may include: in 301, the smart home device enters a listening state.

This step is similar to step 201 and will not be described in detail.

In 302, the smart phone calls the wifi direct interface to send a management frame carrying the service identifier, the service identifier indicating that the networked information service is provided.

For the interface that the management frame is sent, refer to the related description of step 203 shown in FIG. 2, and details are not described herein again.

In this step, the management frame may not carry a specific SSID and password, but carries a service identifier for indicating that the network information service is provided. The service identifier may be a signature or a specific service name.

Similarly, the foregoing steps 301 and 302 may be performed in any order, or simultaneously.

In 303, after the smart home device monitors the management frame including the service identifier, it requests to connect to the smart phone.

In 304, the smart phone accepts the request to establish a connection with the smart home device.

The connection between smart home devices and smart phones is established by wifi direct technology. The following is a brief introduction to the process of establishing a connection by using the wifi direct technology. The connection establishment is as shown in FIG. 4, and mainly includes the following stages: The discovery phase: the smart phone and the smart home device are both in the listening state, and the probe request frame is mutually sent. The probe request frame carries the device identifier of the frame, and the device that listens to the probe request frame replies to the probe response frame, where the probe response frame carries the device identifier of the frame.

Negotiation phase: This phase mainly negotiates the GO (Group Owner) between the smart phone and the smart home device, including the GO negotiation request frame, the GO negotiation response frame, and the GO negotiation. Confirm (GO Negotiation Confirmation) frame. The negotiated GO acts as an AP-like role.

Association phase: Associate and exchange WSC (Wifi Simple Config, wifi configuration information), where the association process includes an association request frame and an association response frame.

Authentication phase: Negotiate authentication information. The authentication here is mainly to negotiate the authentication method of the device as GO to another device. Here, the smart home device and the smart phone can also be used to authenticate the identity of the other party.

Connection phase: The connection is established by the handshake.

In 305, the smart phone sends the SSID and password via a connection established with the smart home device.

In addition to sending the SSID and the password, at least one of the verification information, the encryption information, and the router authentication information may be simultaneously transmitted. The SSID and the password may be encrypted information, and may be a pre-agreed encryption method or an encryption method indicated by the encrypted information carried by the wifi networking information.

At 306, the smart home device accesses the network using the received SSID and password.

The smart home device connects to the wireless router by using the received SSID and password to access the network, and can further utilize the received router authentication information to send an authentication request to the accessed wireless router.

In 307, the smart home device sends a feedback message to the smart phone whether it successfully accesses the network.

In this way, the smart phone can obtain the feedback information of whether the smart home device successfully accesses the network. If the network is successfully accessed, the smart phone can disconnect the connection with the smart home device. If the access network fails, the smartphone can resend the SSID and password via the connection established with the smart home device.

FIG. 5 is a flowchart of a third method according to an embodiment of the present invention. As shown in FIG. 5, the method may include: in 501, a smart home device and a smart phone establish a connection by using a wifi direct technology, by using a connection process. The management frame sent by the smart phone carries the wifi networking information.

It can be seen from the connection establishment process shown in FIG. 4 that the smart phone may send a probe request frame, a probe response frame, an association request frame, a reassociation request frame, and an action frame during the process (optional in the discovery phase and the negotiation phase). In the embodiment of the present invention, the smart phone can send the wifi networking information by using the frame, and the beacon frame is sent (the beacon frame is sent after the handshake is successful).

The wifi networking information can be carried in, but not limited to, the following two methods:

The first mode: the wifi networking information includes at least the feature code, the SSID, and the password. The carrying manner is similar to that in the embodiment shown in FIG. 2, and details are not described herein. It may further include at least one of verification information, encryption information, and router authentication information. In this way, it is not necessary to limit the specific fields of the wifi networking information in the management frame, and the implementation is more flexible.

The second way: the wifi networking information includes at least the SSID and the password, and may not include the signature, and the SSID and the password are carried in the specified extension field of the management frame. That is to say, the management frame is carried at the specified location by performing field extension on the management frame. Similarly, the wifi networking information may further include at least one of verification information, encryption information, and router authentication information.

In 502, the smart home device parses the monitored management frame to obtain wifi networking information.

If the wifi networking information is carried in the first manner, the smart home device first determines whether the feature code included in the monitored management frame is consistent with the preset signature information, and filters out the inconsistent management frame. For a consistent management frame, the SSID and password are parsed from the management frame according to the pre-agreed wifi networking information format.

If the wifi networking information is carried in the second manner described above, the smart home device can parse the SSID and the password from the specified extension field of the management frame.

In 503, the smart home device utilizes the acquired wifi networking information to access the network.

In 504, the smart home device sends a feedback message to the smart phone whether the network is successfully accessed.

The above is a description of the method provided by the present invention, and the apparatus provided by the present invention will be described in detail below with reference to the embodiments.
