Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1 is a flowchart illustrating an information processing method according to an exemplary embodiment, where the method is applied to a wireless access device, as shown in fig. 1, and includes the following steps:

step 11: receiving a first detection request frame sent by intelligent home equipment, wherein a preset field in the first detection request frame carries uplink information;

step 12: analyzing the first detection request frame to obtain a destination address of the uplink information;

step 13: and forwarding the uplink information to the destination address, and returning a first detection response frame to the intelligent home equipment, wherein the first detection response frame is used for feeding back the completion of forwarding the uplink information to the intelligent home equipment.

Here, the wireless access device refers to a device providing a wireless access service in a wireless network, and is a device that can provide information access and allows a wireless terminal to access, for example, a network device such as a router or a switch, and may also be a terminal with a Wi-Fi template built therein, which is not limited in any way in the embodiment of the present disclosure. Here, the terminal may include a mobile terminal, for example, a mobile phone or a tablet computer, or a fixed terminal, for example, a computer, a smart home device, and the like, wherein the smart home device may be, for example, a smart television, a smart refrigerator, a smart washing machine, and the like, and in short, the terminal is a device that can be accessed to the wireless access device as a website. The disclosure takes the smart home device as an example of a terminal accessing to the wireless access device.

It should be noted that the smart home device may scan the accessible wireless access device by broadcasting the probe request frame and receiving the probe response frame, and then compare whether the SSID (Service Set Identifier) of the scanned wireless access device is the SSID that the smart home device is preconfigured to be connected to, and if so, perform access. However, in other embodiments, if the SSID to be connected is not preconfigured in the smart home device, the authentication may be performed through the scanned SSID of the wireless access device, and the wireless access device is accessed after the authentication is passed.

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

hiding the SSID of the wireless access device.

In this embodiment, by hiding the SSID of the wireless access device, it is reduced that the smart home devices recognize and compare the SSID when receiving the probe response frame of the wireless access device, so that on the basis of ensuring that the smart home devices do not need to access the wireless access device, the computing resources of the smart home devices are reduced, the energy consumption of the smart home devices is reduced, and the cruising ability of the smart home devices is improved.

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

The above SSID hiding manner may be: the SSID is hidden by means of encryption or replaced by characters. In a word, the hidden SSID cannot be directly analyzed by the smart home device and the smart home device cannot be directly accessed based on the SSID.

It should be noted that, in the protocol definition of IEEE 802.11 standard for wlan communication, the Vendor-defined field Vendor IE is specified in both the probe request frame and the probe response frame. Here, table 1 is a field format of a custom field Vendor IE in a probe request frame and a probe response frame for replying to the probe request frame:

TABLE 1

It is understood that each of the elements of table 1 are present independently and are exemplarily listed in the same table, but do not represent that all of the elements in the table must be present according to the presentation in the table at the same time. Wherein the value of each element is independent of the value of any other element in table 1. Thus, it will be understood by those skilled in the art that the values of each of the elements in table 1 are separate embodiments.

It should be noted that, because the user-defined field vector IE in the probe request frame and the probe response frame is a field that can be defined by a user, in this way, the embodiment of the present disclosure implements information interaction between the wireless access device and the smart home device by using payload in the user-defined field vector IE. Wherein, payload field in the vector IE can be understood as the load field in the vector IE.

Here, the element identifier is typically a fixed value; the frame length may indicate the maximum number of bytes of the frame, that is, the length of the information frame, where the maximum number of the information frame is 255 bytes; the payload here can be customized by the manufacturer.

It should be noted that the uplink information is carried in the first probe request frame sent by the smart home device, which can be understood as that the uplink information is encapsulated in the first probe request frame by the smart home device. For example, please refer to table 1, encapsulating the uplink information of the smart home device into a first probe request frame includes: and encapsulating the uplink information of the intelligent household equipment in a preset field in the first detection request frame. In some embodiments, the preset field in the first probe request frame may be a payload field of a Vendor IE.

Table 2 below shows the format of the payload field in the first probe request frame:

TABLE 2

It is understood that each of the elements of table 2 are independently present and are exemplarily listed in the same table, but do not represent that all of the elements in the table must be present according to the presentation in the table at the same time. Wherein the value of each element is independent of the value of any other element in table 2. Therefore, as will be understood by those skilled in the art, the values of each of the elements in table 2 are independent embodiments.

Here, the service information types include: service information of a first type. It can be understood that, if the type of the service information is the first type of service information, the service information is uplink information that the smart home device needs to forward and is received by the wireless access device. Generally, the uplink information that the smart home device received by the wireless access device needs to be forwarded to a network server or the like. Of course, the first type of service information may also be uplink information that the smart home device received by the wireless access device needs to forward to the smart home device or the terminal in another network device.

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

Illustratively, encapsulating the uplink information of the smart home device into a first probe request frame includes:

and encapsulating the uplink information of the intelligent home equipment into a service information load field of a payload field of a vector IE in a first detection request frame, and setting a service information type field in the payload field of the vector IE as first-class service information. Here, if the service information type is the first type of service information type, it indicates that the service information carries uplink information.

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

analyzing a payload field in a Vendor IE field in the first detection request frame, and reading a service information type field in the payload field;

and determining that the first probe request frame carries uplink information according to the fact that the read service information type is the first type service information type.

Here, the determining that the first probe request frame carries uplink information according to the fact that the read service information type is a first type of service information type includes:

it should be noted that, when the smart home device sends the uplink information to the wireless access device, the destination address corresponding to the uplink information is sent to the wireless access device together, so that the wireless access device can forward the uplink information to the destination address to complete the forwarding process of the uplink information.

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

and determining the destination address of the uplink information according to the destination address carried by the uplink information.

Here, the destination address carried by the uplink information includes: reading a destination address in a data packet header field of the uplink information; or, the destination address read from the load field in 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 placed in a payload field in the data packet of the uplink information, so that the security of the uplink information is improved.

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

and determining the destination address of the uplink information according to the equipment identifier carried by the uplink information and the destination address corresponding to the equipment identifier pre-stored by the wireless access equipment.

It should be noted that, in some scenarios, for example, for an intelligent home device of some manufacturers, since only communication with a server of the manufacturer is required, at this time, the device identifier and the destination address of the intelligent home device are fixed, the device identifier and the corresponding destination address of the intelligent home device of the manufacturer may be pre-stored in the wireless access device, and thus, when the intelligent home device needs to forward uplink information via the wireless access device, it is not necessary to send the destination address to the wireless access device every time, so that the data amount of data interaction is reduced, and the efficiency of data interaction is improved.

Of course, for the case that the communication object of the smart home device is not fixed, the method may further include: and if the uplink information does not carry a destination address, determining the destination address of the uplink information according to the equipment identifier carried by the uplink information and the destination address corresponding to the equipment identifier pre-stored by the wireless access equipment.

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

In some embodiments, the default destination address may be set according to a manufacturer of the smart home device, for example, a server address corresponding to the manufacturer of the smart home device is set as the default destination address.

For example, for a smart watch of a certain manufacturer, if the smart watch needs to perform network access other than the manufacturer, for example, hundreds of network access, the uplink information may carry a corresponding network address to be accessed, and if the smart watch of the manufacturer only uploads measured parameters such as step number or heartbeat to a server of the manufacturer, the address of the server of the manufacturer may be set as a default destination address.

In other embodiments, the default destination address may be according to the history access server frequency device of the smart home device, that is, a server address corresponding to a history access server with a highest address may be set as the default destination address.

In this embodiment, the destination address of the uplink information is determined by the device identifier carried by the uplink information and the destination address corresponding to the device identifier pre-stored in the wireless access device, and since the destination address does not need to be carried in the uplink information, the data volume of the uplink information is reduced, so that the load in the data field of the first probe request frame carrying the uplink information is saved, and the data volume that can be carried by the first probe request frame can be increased.

In the above embodiment, the wireless access device can receive the uplink information that the smart home device needs to forward through the first probe request frame, and can forward the uplink information to the destination address of the uplink information. Therefore, the wireless access device can still serve as a transfer device of the smart home device to assist the smart home device to send the uplink information to the destination address of the uplink information without establishing authentication connection with the smart home device, so that the wireless access device can be used as the transfer device without being limited by the number of the access devices, that is, the smart home device does not need to be accessed to the wireless access device, and therefore any smart home device within the coverage range of the wireless access device can forward the uplink information by using the wireless access device, and therefore, the number of devices capable of being transferred in the wireless access device is greatly expanded, which is equivalent to improving the access capability of the wireless access device.

Further, in this embodiment, the wireless access device can forward uplink information for all the smart home devices within the coverage area of the wireless access device, and is not limited by the number of the access devices of the wireless access device, so that the problem that a plurality of smart home devices cannot be networked when a scene in which a large number of smart home devices need to be accessed exists in the current wireless local area network is solved.

It should be added that, each wireless access device in the network system can implement the interaction of the service data according to the method described in the above embodiment, so that the wireless access device can provide the relay for the nearby smart home devices, and thus, the network connection does not need to be performed in a traditional manner that one wireless access device, such as a wireless router, is used as a center, so that the network coverage of the entire network system is wider.

For example, taking a home network environment as an example, in the related art, each smart home device in the home network environment performs network connection through an access router, however, when the router is far away from another smart home device, phenomena such as connection failure or frequent disconnection of an unstable window of the network may occur. Based on this, if the smart home devices have the function of the wireless access device, in this embodiment, the wireless access device may be any smart home device in the home environment, and thus, by using each smart home device distributed in the home network environment as the wireless access device, the uplink information of other smart home devices at any position may be forwarded to the router, or directly forwarded to the network server. Thus, the network coverage in the home network environment is considerably improved.

Referring to fig. 2 as an alternative embodiment, fig. 2 is another flowchart illustrating an information processing method according to an exemplary embodiment, where as shown in fig. 2, the method further includes:

step 21: receiving a second detection request frame sent by the intelligent home equipment, wherein the second detection request frame is used for requesting to inquire downlink information;

step 22: determining whether the downlink information is cached locally;

step 23: and sending a second detection response frame to the intelligent home equipment under the condition of determining that the downlink information is cached locally, wherein a preset field in the second detection response frame carries the downlink information.

It should be added that, referring to table 2, the service information types may further include: second type service information; and if the service information type is the second type of service information, the service information is shown to contain downlink information issued to the intelligent household equipment. In some embodiments, in step 23, the sending the second probe response frame to the smart home device may include: the downlink information is added to the payload field of the Vendor IE in the second probe response frame. In some other embodiments, the sending the second probe response frame to the smart home device may further include: and encapsulating the downlink information into a service information load field in the payload field, and setting a service information type field in the payload field of the Vendor IE as a second type of service information type.

In this way, in this embodiment, the wireless access device may send the downlink information to the smart home device in a manner that the second probe response frame is fed back to the smart home device. Therefore, the downlink information can be sent to the intelligent home equipment through the second detection response frame without the intelligent home equipment accessing the wireless access equipment, so that network transfer of the wireless access equipment in a wireless access state is realized, and interaction of the uplink information and the downlink information is performed between the wireless access equipment and the intelligent home equipment without authentication connection.

It is to be supplemented that, after receiving the downlink information sent to the smart home device by the network server, the wireless access device caches the downlink information, and sends the downlink information to the smart home device when the smart home device initiates a request to the wireless access device to query the downlink information, so that the memory of the smart home device can be lightened.

It is further to be supplemented that the sending, by the smart home device, the second probe request frame to the target wireless access device may include: and adding the request information of the intelligent household equipment for requesting to inquire the downlink information into a preset field. It is understood that in the protocol definition of the IEEE 802.11 standard of the existing wireless lan communication, the Vendor-defined field Vendor IE is specified in both the probe request frame and the probe response frame. In some embodiments, the preset field in the second probe request frame may be a payload field of a vector IE.

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

and encapsulating the request information of the intelligent home equipment for requesting to inquire the downlink information into a service information load field of a payload field of a Vendor IE of the first detection request frame, and setting a service information type field in the payload field of the Vendor IE as a third type service information type. Here, if the service information type is the third type of service information type, it indicates that the service information carries request information for requesting downlink information of the wireless access device.

In some embodiments, the query downlink information is requested from the wireless access device as soon as the smart home device is powered on. For example, after the intelligent water meter is powered on, the current water usage condition needs to be acquired.

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

and receiving a second detection request frame sent by the intelligent household equipment under the condition that the intelligent household equipment is in a working state.

It can be understood that the states of the smart home devices may include: an active state and a sleep state. Wherein, the working state includes: and the state of the smart home after being powered on.

It should be noted that the distance is determined according to the energy intensity of the received signal. Here, the stronger the RSSI, the smaller the distance between the wireless access device and the smart home device, the smaller the signal attenuation, and the higher the communication quality.

Further, the embodiments of the present disclosure also provide a specific embodiment to further understand the information processing method provided by the embodiments of the present disclosure.

In the home network environment, more and more access devices are used, and due to the access capability limitation of the router and the interference of the surrounding wireless environment, the situation that the access devices are off-line or even cannot be controlled often occurs. Therefore, how to improve the access capability of the router in the home network environment becomes a technical problem which needs to be solved urgently.

Based on this, fig. 5 is a flow chart illustrating an information processing method according to one embodiment, as shown in fig. 5,

here, the device corresponding to the destination address of the uplink information takes a cloud server as an example, and it should be noted that the cloud server is a server of a manufacturer of the smart home device, and is configured to provide network service data for the smart home device, where the wireless access device in this embodiment may be a router, and the specific method includes the following steps:

step 51: and powering on the intelligent household equipment to start searching the father node.

Here, the parent node is actually a router, and here, finding the parent node is a process of sending an access request to each of the surrounding candidate routers, and selecting an appropriate router from the candidate routers for access.

Step 61: and after the router is powered on, the hidden SSID is started.

Here, the hidden SSID is to avoid the smart home device from directly establishing a connection with the router based on the SSID, so the hidden SSID is started before the router is powered on, and thus the smart home device cannot establish a connection with the router.

Step 52: and the intelligent household equipment broadcasts a third detection request frame containing the access request message.

In this step, the service information type in the service information type field in the payload field in the third probe request frame is configured to be a fourth type service data type, that is, if the service information type is the fourth type service information type, it indicates that the service information carries request information for requesting the access capability information of the wireless access device. The smart home device sends a probe data frame containing an access request message to a router, wherein the probe data frame carries request information for requesting the access capability information of the router.

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

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

Step 53: and selecting a proper father node according to the access capability information.

Here, the smart home device may select a suitable router as a target router according to the received access capability information of each candidate router to send the first probe request frame according to the above embodiment.

Here, selecting an appropriate parent node according to the access capability information may include two ways described in the above embodiments:

the first method is as follows: determining a plurality of difference values of the received signal strength indication between two alternative routers based on the access capability information of the alternative routers; and if at least one difference value in the plurality of difference values is larger than a first difference value threshold value, selecting the corresponding alternative router with the strongest signal strength indicated by the received signal strength as the target router.

The second method is as follows: and if the plurality of differences are all smaller than a second difference threshold, selecting the corresponding alternative wireless access equipment with the minimum ratio in the ratio of the number of the proxied equipment of the alternative wireless access equipment to the number of the maximum proxied equipment as the target wireless access equipment.

Step 54: the occurrence of a triggering event is sent.

Here, the smart home device monitors the sending trigger event of the first probe request frame, and actually, the smart home device monitors the sending event of the uplink information to be sent.

Step 55: the intelligent home equipment sends a first detection request frame carrying uplink information.

And step 63: the router analyzes the uplink information and forwards the uplink information to the cloud server.

Here, the router parses the uplink information according to the payload field in the probe data frame containing the uplink information, and forwards the uplink information to the corresponding cloud server. It can be understood that, in this embodiment, the address of the cloud server is the default upload address of the smart home device, so the router can directly send the uplink data to the cloud server.

Step 71: and the cloud server sends the downlink information to the router.

Step 64: and caching the downlink information by the router, and recording the equipment identifier corresponding to the downlink information in an equipment identifier list.

Here, the device identification list includes: and the corresponding relation list of the equipment identification and the downlink information. After the router receives the downlink information sent by the cloud-end server, for some reason, for example, because the smart home devices are in a dormant state, or under the condition that the smart home devices do not need to acquire the downlink information, the router may temporarily cache the downlink information, so that the space is saved for the smart home devices. In addition, by recording the equipment identifier list, the downlink information to be issued can be conveniently and rapidly found according to the equipment identifier of the intelligent household equipment when the intelligent household equipment needs the router to issue the downlink data.

Step 56: and the intelligent household equipment sends a second detection request frame carrying request information for inquiring the downlink information.

Here, the request information for requesting to query the downlink information is encapsulated in the probe data frame, and the query request message carries the device identifier of the smart home device, so that the router can conveniently send the corresponding downlink information to the smart home device based on the device identifier.

Step 65: and comparing the device identification, and replying the downlink information if finding the device identification corresponding to the downlink information.

The device identifier here may be understood as the device identifier of the smart home device described in the above embodiment.

And step 66: the router returns the downlink information.

Here, the router encapsulates the downlink information in a second probe response frame, and replies the second probe response frame to the smart home device. Therefore, the intelligent household equipment and the router do not need to establish authentication connection for information interaction.

In this embodiment, the uplink information is encapsulated in the second detection response frame and sent to the cloud server via the router, and the downlink information sent by the cloud server is encapsulated in the second detection response frame by the router and sent to the smart home device. Therefore, the interaction of the service information between the smart home devices and the cloud server is completed by the transmission of the first detection request frame and the second detection response frame in the embodiment, so that the smart home devices do not need to be substantially connected with the router, that is, the target connection can also realize the function of forwarding data, and the number of devices accessed by the router is not counted. Therefore, the embodiment is not limited by the router access device, so that the same router can be used as the transfer device of an unlimited number of smart home devices, which is equivalent to improving the access capability of the router.

The number of access devices in the home network environment is increasing, due to the access capability limitation of the router and the interference of the surrounding wireless environment, the access devices are often offline, even the access devices cannot be controlled, and as the living level of people increases, the area covered by the home network environment is also increasing, and the network coverage area of the router is limited. Therefore, how to increase the network coverage of the router in the home network becomes a technical problem which needs to be solved urgently.

Based on this, in combination with the scheme of the foregoing embodiment, an intermediate access point is introduced, where the intermediate access point may be a router that does not establish, for example, an authenticated connection with the smart home device as described in the foregoing embodiment. In practical application, the intermediate access point may be a router, or may be a device such as an intelligent home device having an access function.

Specifically, fig. 6 is another flowchart of an information processing method according to an embodiment, and as shown in fig. 6, it should be noted that the router here has established wifi connection with an intermediate router as a network device.

Here, the device corresponding to the destination address of the uplink information takes a router connected to a cloud server as an example, it should be noted that the cloud server is a server of a manufacturer of the smart home device and is configured to provide network service information for the smart home device, and the intermediate access point in this embodiment is any device that can be used as a wireless access device in a home network, for example, a mobile phone or a smart television. Here, any device in the home network that can be used as a wireless access device is introduced into the intermediate access point device described in this embodiment, so that the range of the network that can be covered by the router is wider.

It can be understood that the router only needs to be connected with the intermediate access point, and in the case that the distance between the smart home device and the router is too long to receive the radio signal sent by the router, the intermediate access point still can perform service data interaction with the router, thereby equivalently improving the network coverage of the router.

The method comprises the following specific steps:

Step 81: and after the intermediate access equipment is powered on, the hidden SSID is started.

Here, the hidden SSID is to avoid the smart home device from directly establishing a connection with the intermediate access point based on the SSID, so that the hidden SSID is started before the intermediate access point is powered on, and thus the smart home device cannot establish a connection with the intermediate access point.

Step 52: and the intelligent household equipment broadcasts a third detection request frame containing the access request.

It should be noted that the router may also receive a probe data frame including an access request broadcast by the smart home device.

Step 83: the intermediate access equipment returns the access capability information.

And step 92: the router returns access capability information.

Here, the access capability information may be carried in the third probe response frame and returned to the smart home device.

Here, the smart home device may select a suitable wireless access device as a target wireless access device to send the first probe data frame according to the received access capability information of each candidate wireless access device.

Step 54: the occurrence of a triggering event is sent.

Step 84: the intermediate access equipment analyzes the uplink information and forwards the uplink information to the cloud server.

Here, the intermediate access device parses the uplink information according to the payload field in the first probe request frame containing the uplink information, and forwards the uplink information to the router, and then the router forwards the uplink information to the corresponding cloud server. It can be understood that, in this embodiment, the address of the cloud server is the default uploading address of the smart home device, so that after the intermediate access device sends the uplink information to the router, the router can directly send the uplink information to the cloud server.

Step 93: the router forwards the upstream information.

Step 71: and the cloud server issues downlink information.

Step 94: the router forwards the downlink information.

Step 85: and the intermediate access equipment caches the downlink data and records the equipment identification corresponding to the downlink information in an equipment identification list.

Step 56: and the intelligent household equipment sends an inquiry request to the router.

The request information for requesting to inquire the downlink information is encapsulated in the detection data frame, and the inquiry request information carries the equipment identifier of the intelligent home equipment, so that the intermediate access equipment can conveniently send the corresponding downlink information to the intelligent home equipment based on the equipment identifier.

Step 86: and comparing the device identification, and replying the downlink information if finding the device identification corresponding to the downlink information.

Step 87: and the intermediate access equipment returns downlink information to the intelligent household equipment.

Here, the intermediate access device also encapsulates the downlink information in the second probe response frame, and replies the second probe response frame to the smart home device. Therefore, the intelligent household equipment and the intermediate access equipment do not need to establish authentication connection to carry out information interaction.

According to the embodiment of the disclosure, by introducing the intermediate access device, when the distance between the router and the smart home device is long, the service information can be forwarded through the intermediate access device, which is equivalent to increase of the network coverage of the router.
