Here, wireless access devices refer to devices that provide wireless access services in wireless networks, devices that can provide information access and allow wireless terminals to access, for example, network devices such as routers or switches, which can also have built-in Wi-Fi The terminal of the template is not subject to any limitation in the embodiment of this disclosure. Here, the terminal may include a mobile terminal or a fixed terminal. The mobile terminal may be, for example, a mobile phone or a tablet computer. The fixed terminal may be, for example, a computer or a smart home device. The smart home device may be, for example, a smart TV, a smart home device, etc. Refrigerator or smart washing machine, etc. In short, the terminal is a device that can be connected to the wireless access device as a site. This disclosure takes a smart home device as a terminal connected to a wireless access device as an example.

It should be noted that smart home devices can scan for accessible wireless access devices by broadcasting detection request frames and receiving detection response frames, and then compare the SSID (Service SetIdentifier, Service Set) of the scanned wireless access devices. Identifier) is the SSID to be connected pre-configured? If so, access is performed. Of course, in other embodiments, if the smart home device is not pre-configured with the SSID to be connected, authentication can be performed through the scanned SSID of the wireless access device, and the wireless access device can be accessed after passing the authentication.

In some implementations, before step 11, that is, before receiving the first detection request frame sent by the smart home device, the method further includes:

Hide the SSID of the wireless access device.

In this embodiment, by hiding the SSID of the wireless access device, the process of identifying and comparing the SSID when the smart home device receives the detection response frame of the wireless access device is reduced, thereby ensuring that the smart home device does not need to receive On the basis of integrating wireless access devices, it reduces the computing resources of smart home devices and reduces the energy consumption of smart home devices to improve the battery life of smart home devices.

Of course, in other embodiments, the wireless access device turns on the hidden SSID when it is powered on.

The above-mentioned method of hiding the SSID can be: hiding the SSID through encryption, or replacing the SSID with characters. In short, the hidden SSID will not be directly parsed by smart home devices and smart home devices cannot be directly connected based on the SSID.

It should also be noted that in the protocol definition of IEEE 802.11, the standard for wireless LAN communication, the vendor-defined field Vendor IE is specified in both the detection request frame and the detection response frame. Here, Table 1 shows the field format of the custom field Vendor IE in the probe request frame and the probe response frame used to reply to the probe request frame:

Table 1

It can be understood that each element in Table 1 exists independently, and these elements are exemplarily listed in the same table, but this does not mean that all elements in the table must exist at the same time as shown in the table. Among them, the value of each element does not depend on the value of any other element in Table 1. Therefore, those skilled in the art can understand that the value of each element in Table 1 is an independent embodiment.

It should be noted that since the custom field Vendor IE in the detection request frame and the detection response frame is a field that can be customized by the user, the embodiment of the present disclosure uses the payload in the custom field Vendor IE to implement the wireless access device. Information interaction with smart home devices. Among them, the payload field in Vendor IE can be understood as the payload field in Vendor IE.

Here, the element identifier is generally a fixed value; the frame length can indicate the maximum number of bytes of the frame, which is the length of the information frame. Here, the maximum information frame is 255 bytes; the payload here can be Manufacturer customized.

It should be noted that the first detection request frame sent by the smart home device carries uplink information. It can be understood that the smart home device encapsulates the uplink information into the first detection request frame. For example, please refer to Table 1. Encapsulating the uplink information of the smart home device into the first detection request frame includes: encapsulating the uplink information of the smart home device in the predefined first detection request frame. in the setting field. In some embodiments, the preset field in the first detection request frame may be the payload field of the Vendor IE.

Below, Table 2 shows the format of the payload field in the first detection request frame:

Table 2

It can be understood that each element in Table 2 exists independently, and these elements are exemplarily listed in the same table, but this does not mean that all elements in the table must exist at the same time as shown in the table. Among them, the value of each element does not depend on the value of any other element in Table 2. Therefore, those skilled in the art can understand that the value of each element in Table 2 is an independent embodiment.

Here, the business information types include: first type of business information. It can be understood that if the service information type is the first type of service information, then the service information is uplink information received by the wireless access device and needs to be forwarded by the smart home device. Usually it is the uplink information received by the smart home device that needs to be forwarded to the network server etc. by the wireless access device. Of course, the first type of service information may also be uplink information received by the smart home device from the wireless access device and needs to be forwarded to the smart home device or terminal in other network devices.

In some embodiments, please refer to Table 2 again. The preset field may also be the service information payload field in the payload field.

Exemplarily, encapsulating the uplink information of the smart home device into the first detection request frame includes:

The uplink information of the smart home device is encapsulated into the service information load field of the payload field of the Vendor IE of the first detection request frame, and the service information type field in the payload field of the Vendor IE is set to the first type of service information. Here, if the service information type is the first type of service information type, it means that the service information carries uplink information.

In other embodiments, step 12, that is, parsing the first probe request frame, may include:

Parse the payload field in the Vendor IE field in the first detection request frame, and read the service information type field in the payload field;

According to the read service information type being the first type of service information, it is determined that the first detection request frame carries uplink information.

Here, based on the fact that the read service information type is the first type of service information, it is determined that the first detection request frame carries uplink information, including:

It should be noted that when the smart home device sends uplink information to the wireless access device, the destination address corresponding to the uplink information will be sent to the wireless access device. In this way, the wireless access device can forward the uplink information to the wireless access device. In the destination address, the forwarding process of the uplink information is completed.

In some embodiments, in step 12, obtaining the destination address of the uplink information includes:

The destination address of the uplink information is determined according to the destination address carried by the uplink information.

Here, the destination address carried by the uplink information includes: the destination address read in the header field of the data packet of the uplink information; or the destination address read in the payload field of the data packet of the uplink information.

It should be noted that since the header of the data packet is usually not encrypted, in some embodiments, the destination address of the uplink information is put into the payload field in the data packet of the uplink information. In this way, the accuracy of the uplink information is improved. safety.

In other embodiments, obtaining the destination address of the uplink information includes:

The destination address of the uplink information is determined based on the device identifier carried in the uplink information and the destination address corresponding to the device identifier pre-stored by the wireless access device.

It should be noted that in some scenarios, for example, smart home devices from certain manufacturers only need to communicate with the server of that manufacturer. At this time, the device ID and destination address of the smart home device are fixed, so , the device identification and corresponding destination address of the manufacturer's smart home device can be pre-stored in the wireless access device. In this way, when the smart home device needs to forward uplink information through the wireless access device, it does not need to be forwarded every time. The destination address is sent to the wireless access device to reduce the amount of data exchange and improve the efficiency of data exchange.

Of course, when the communication object of the smart home device is not fixed, the method may also include: if the uplink information does not carry a destination address, based on the device identification carried by the uplink information, and the wireless access The destination address corresponding to the device identification stored in advance by the device determines the destination address of the uplink information.

Here, the destination address corresponding to the device identifier that can be pre-stored in the wireless access device is the default destination address of the smart home device corresponding to the device identifier. That is to say, when the smart home device needs to send uplink information, if it does not carry the destination address, the default destination address is used as the destination address of the uplink information.

In some implementations, the default destination address can be set according to the manufacturer of the smart home device. For example, the server address corresponding to the manufacturer of the smart home device is set as the default destination address.

For example, for a smart watch from a certain manufacturer, if the smart watch needs to access a network other than the manufacturer, for example, Baidu's network, the uplink information can carry the corresponding network address that needs to be accessed, and the uplink information can carry the corresponding network address that needs to be accessed. If a manufacturer's smart watch only uploads measured steps or heartbeat parameters to the manufacturer's server, the address of the manufacturer's server can be set as the default destination address.

In other embodiments, the default destination address may be based on the frequency of the smart home device's historical access to the server. That is, the corresponding server address with the highest historical access to the server may be set as the default destination address.

In this embodiment, the destination address of the uplink information is determined through the device identifier carried in the uplink information and the destination address corresponding to the device identifier pre-stored by the wireless access device. Since there is no need to carry the destination address in the uplink information , reducing the data amount of the uplink information, thus saving the load in the data field of the first probe request frame carrying the uplink information, thereby increasing the amount of data that the first probe request frame can carry.

In the above embodiment, the wireless access device can receive the uplink information that the smart home device needs to forward through the first detection request frame, and can forward the uplink information to the destination address of the uplink information. In this way, the wireless access device can still serve as a transit device for the smart home device to assist the smart home device in sending uplink information to the destination address of the uplink information without establishing, for example, an authentication connection with the smart home device. In this way, As a transit device, wireless access devices are not limited by the number of access devices. That is to say, since smart home devices do not need to access the wireless access device, any smart home device within the coverage of the wireless access device All home devices can use the wireless access device to forward uplink information. Therefore, the number of devices that the wireless access device can be relayed is greatly expanded, which is equivalent to improving the access capability of the wireless access device.

Furthermore, since in this embodiment, the wireless access device can forward uplink information to all smart home devices within the coverage range of the wireless access device and is not limited by the number of access devices of the wireless access device, therefore , which solves the problem of multiple smart home devices being unable to connect to the Internet when there are many smart home devices in the current wireless LAN that need to be connected.

It should be added that since each wireless access device in the network system can implement service data interaction according to the method described in the above embodiment, the wireless access device can provide relay for nearby smart home devices. In this way, no need to Relying on the traditional way of network connection centered on a wireless access device such as a wireless router makes the network coverage of the entire network system wider.

For example, take the home network environment as an example. In related technologies, each smart home device in the home network environment is connected to the network through an access router. However, when the router is far away from other smart home devices, there may be an inability to connect or network failure. The stable window often drops offline and other phenomena. Based on this, if the smart home device has the function of a wireless access device, in this embodiment, the wireless access device can be any smart home device in the home environment. In this way, through the wireless access device distributed in the home network environment Each smart home device, as a wireless access device, can forward the uplink information of other smart home devices at any location to the router, or directly to the network server. In this way, it is equivalent to improving the network coverage in the home network environment.

As an optional embodiment, please refer to Figure 2, which is another flow chart of an information processing method according to an exemplary embodiment. As shown in Figure 2, the method further includes:

Step 21: Receive the second detection request frame sent by the smart home device, where the second detection request frame is used to request to query downlink information;

Step 22: Determine whether the downlink information is cached locally;

Step 23: When it is determined that the downlink information is cached locally, send a second detection response frame to the smart home device, where the preset field in the second detection response frame carries the downlink information.

It should be added that, please refer to Table 2 again. The business information type may also include: second type of business information; if the business information type is the second type of business information, it means that the business information includes the information sent to the smart home device. downward information. In some embodiments, in step 23, sending a second detection response frame to the smart home device may include: adding downlink information to the payload field of the Vendor IE in the second detection response frame. In other embodiments, sending the second detection response frame to the smart home device may also include: encapsulating the downlink information into the service information load field in the payload field, and converting the downlink information into the payload field of the Vendor IE. The business information type field is set to the second type of business information type.

In this way, in this embodiment, the wireless access device can send the downlink information to the smart home device in a manner that the second detection response frame is fed back to the smart home device. In this way, the smart home device does not need to be connected to the wireless access device, and the downlink information can be sent to the smart home device through the second detection response frame, thereby realizing network relay of the wireless access device in the wireless access state. , thereby allowing the wireless access device and the smart home device to interact with uplink and downlink information without requiring, for example, authentication connection.

It should be added that after receiving the downlink information sent by the network server to the smart home device, the wireless access device will cache the downlink information until the smart home device initiates a request to the wireless access device to query the downlink information. Send it to the smart home device, so that the memory of the smart home device can be lightweight.

It should be added that the smart home device sending the second detection request frame to the target wireless access device may include: adding the request information of the smart home device for requesting downlink information query to a preset field. It can be understood that in the protocol definition of the existing wireless LAN communication standard IEEE 802.11, the vendor-defined field Vendor IE is specified in both the detection request frame and the detection response frame. In some embodiments, the preset field in the second detection request frame may be the payload field of the Vendor IE.

In some embodiments, sending a second probe request frame to the target wireless access device includes:

Encapsulate the request information of the smart home device for querying downlink information into the service information load field of the payload field of the Vendor IE of the first detection request frame, and set the service information type field in the payload field of the Vendor IE It is the third type of business information. Here, if the service information type is the third type of service information type, it means that the service information carries request information requesting downlink information of the wireless access device.

In some embodiments, as soon as the smart home device is powered on, it requests downlink information from the wireless access device. For example, after the smart water meter is powered on, it needs to obtain the current water usage status, etc.

In some embodiments, receiving the second detection request frame sent by the smart home device may further include:

When the smart home device is in a working state, receive a second detection request frame sent by the smart home device.

It can be understood that the status of smart home devices can include: working status and dormant status. Among them, the working status includes: the status after the smart home is powered on. It is understandable that for some IoT smart home devices, such as smart water meters, when the smart water meter sends an instruction to obtain water status information for the current month through the wireless access device, it enters a dormant state to save power, and the corresponding server receives After the instruction, the corresponding water status information will be sent to the wireless access device.

There are more and more access devices in the home network environment. Due to the limitations of router access capabilities and interference from the surrounding wireless environment, access devices often go offline or even become uncontrollable. Therefore, how to improve the access capabilities of routers in home network environments has become an urgent technical issue that needs to be solved.

Based on this, Figure 5 is a flow chart of an information processing method according to a specific embodiment. As shown in Figure 5,

Here, the device corresponding to the destination address of the uplink information is a cloud server as an example. It should be noted that the cloud server is a server of a smart home device manufacturer and is used to provide network service data for smart home devices. The wireless interface in this embodiment The incoming device can be a router. The specific steps are as follows:

Step 51: Power on the smart home device and start searching for the parent node.

The parent node here is actually a router. Here, finding the parent node is the process of sending access requests to various surrounding alternative routers, and selecting a suitable router from the alternative routers for access.

Step 61: Turn on the hidden SSID after powering on the router.

Here, the purpose of hiding the SSID is to prevent smart home devices from directly establishing a connection with the router based on the SSID. Therefore, after the router is powered on, the hidden SSID is enabled first, so that the smart home devices cannot establish a connection with the router.

Step 62: The router returns the third detection response frame carrying access capability information.

Here, the router returns the access capability information of the smart home device itself based on step 51.

Step 53: Select an appropriate parent node based on the access capability information.

Here, the smart home device will select an appropriate router as the target router based on the received access capability information of each candidate router to send the first detection request frame described in the above embodiment.

After the router receives the downlink information sent by the cloud server, for some reason, such as because the smart home device is sleeping, or the smart home device does not need to obtain the downlink information, the router can temporarily cache the downlink information. , thus saving space for smart home devices. In addition, by recording the device identification list, it is convenient to quickly find the downlink information to be distributed based on the device identification of the smart home device when the smart home device needs the router to deliver downlink data.

Step 56: The smart home device sends a second detection request frame carrying request information for querying downlink information.

In this way, it is convenient for the router to send the corresponding downlink information to the smart home based on the device identification. equipment.

Step 65: Compare the device identification. If a device identification corresponding to the downlink information is found, reply the downlink information.

The device identification here can be understood as the device identification of the smart home device described in the above embodiment.

Step 66: The router returns the downlink information.

Here, the router will encapsulate the downlink information in the second detection response frame, and reply the second detection response frame to the smart home device. In this way, smart home devices and routers do not need to establish an authentication connection to exchange information.

In this way, the interaction of business information between the smart home device and the cloud server is completed through the transmission of the first detection request frame and the second detection response frame described in the above embodiment. In this way, there is no need for the smart home device and the router to perform substantial interactions. The connection, that is, the target connection mentioned above, can also realize the data forwarding function and will not be counted in the number of devices connected to the router. Therefore, this embodiment is not limited by router access devices, so that the same router can be used as a transit device for an unlimited number of smart home devices, which is equivalent to improving the access capability of the router.

Here, by introducing any device in the home network that can be used as a wireless access device as the intermediate access point device described in this embodiment, the network range that the router can cover can be made wider.

It can be understood that the router only needs to connect to the intermediate access point. When the distance between the smart home device and the router is too far to receive the radio signal sent by the router, the intermediate access point can still communicate with the router. The exchange of business data is equivalent to improving the network coverage of the router.

The specific method steps are as follows:

Step 51: Power on the smart home device and start searching for the parent node.
