Detailed ways

In order to improve the success rate of configuration, the present invention provides a method and apparatus for device network access configuration. The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to illustrate the present invention, but not to limit the present invention.

As shown in FIG. 1 , in an embodiment of the present invention, a device network access configuration method is used for wireless access points, and the method includes the following steps:

S101: Receive request information for configuring network access by a device; wherein, the request information is generally initiated by a user. For example, the user starts at the router management page.

S102: Load the network access configuration data into the vendor-specific information field of the beacon frame.

S103: Broadcast the beacon frame, so that the device in the configuration state obtains the network access configuration data from the received beacon frame; the frame identifier is used to identify that the beacon frame carries the network access configuration data.

The embodiment of the present invention abandons the way of configuring by multicast, uses a Beacon (beacon) frame to carry all configuration data, and broadcasts and sends the Beacon frame by a routing device, which can provide a larger radiation range. And because the Beacon frame is a standard frame of the Wifi protocol, the technology is mature, and the Wifi device supports the frame steadily, which can greatly optimize the compatibility. At the same time, since a single beacon frame can carry all configuration data, the problem of packet grouping is not involved, and the configuration success rate can be effectively guaranteed.

On the basis of the above-mentioned embodiments, modified embodiments of the above-mentioned embodiments are further proposed. It should be noted here that, in order to simplify the description, only the differences from the above-mentioned embodiments are described in each of the modified embodiments.

In an embodiment of the present invention, before the step of broadcasting the beacon frame, the method further includes:

Obtain the manufacturer information of the device that needs to be configured to access the network, determine the frame identifier used to identify the network access configuration data carried in the beacon frame according to the manufacturer information, and load the frame identifier into the manufacturer-specific information field of the beacon frame middle.

The Beacon frame is a standard management frame specified by the 802.11 protocol of Wifi. The Wifi device regularly broadcasts the Beacon frame to notify the existence of an AP (Wireless Access Point, wireless access point) in the network. In addition to carrying some basic information of Wifi, the Beacon frame also allows Wifi device manufacturers to provide customized information in the manufacturer-specific information field. Based on this embodiment of the present invention, the network access configuration data and the frame identification are loaded into the vendor-specific information field of the beacon frame. The implementation of the present invention is simple in principle, effectively reduces the implementation complexity, and does not need to change the protocol regulation of the Beacon frame.

Specifically, the user selects the smart home appliance configuration option on the router management page, and selects the manufacturer information of the new home appliance. If found, it means that the home appliance of the manufacturer and the router manufacturer have negotiated the use of the manufacturer-specific information field in the Beacon frame. The wireless access point (such as a router) configures the network access process for the manufacturer's home appliances.

A wireless access point (such as a router) sends a Beacon frame. The data area of the frame includes a frame identifier. The frame identifier can be 4 consecutive bytes of data to indicate that the frame carries network configuration data. For example, a device (smart home appliance) After receiving the Beacon frame, the device determines whether there are 4 consecutive bytes of specific information in the data area. If there is, it means that the frame uses the manufacturer-specific information field, and then obtains the network access configuration data from this field.

Wherein, the wireless access point includes a router and a device with a routing function, such as a mobile terminal (including a mobile phone).

Further, in this step, the network access configuration data can be carried in two forms: one is to carry the SSID and password in the data area of the Beacon frame, the other is to carry the SSID information in the SSID field of the Beacon frame, and carry the SSID information in the data area. Password; the operation of this step will continue to send for 1 minute.

That is to say, the network access configuration data includes two types of configuration information: a network access password and a service set identifier; or,

The network access configuration data includes configuration information of a network access password, and the service set identifier is carried in the SSID field of the beacon frame.

Still further, the vendor-specific information field includes a packet header, the type of the configuration information entry, the entry header and each of the configuration information entries, wherein: the network access configuration data and the frame identifier are loaded into the The steps in the vendor-specific information field of the beacon frame, including:

Encapsulating the configuration information in the network access configuration data in corresponding types of configuration information entries;

Encapsulate the length information of each of the configuration information entries in the entry header;

determining the total length of each of the configuration information entries and the entry header;

Encapsulate the length sum information and the frame identification in the packet header;

The packet header, the type of the configuration information entry, the entry header and each of the configuration information entries are loaded into a vendor specific information field of the beacon frame.

Wherein, the type of the configuration information entry includes the first method: the network access password type and the service set identification type; or the second method: the network access password type.

That is to say, in this embodiment, the network access configuration data and the frame identifier are encapsulated into a configuration data packet in the form of a configuration header, an entry header and a configuration entry, and the configuration data is encapsulated into the beacon frame. in the Vendor Specific Information field.

The embodiments of the present invention encapsulate vendor-specific field data in the form of configuration header, entry header, and configuration entry, adopt configuration entry to encapsulate configuration data, and determine entry (configuration information) location by configuration entry length, which can be easily extended.

The steps of encapsulating the network access configuration data and the frame identifier are described in detail below.

Assembly configuration information entry (referred to as entry):

Step 1. The network access configuration data includes two types of configuration information, namely, network access password configuration information and service set identification configuration information. In this embodiment of the present invention, the network access password must be carried in the vendor-specific information field, and the service set identifier can be carried in the vendor-specific information field or in the SSID field of the beacon frame; therefore, the network access configuration data is divided into SSID (service set identifier). ) and KEY (network access password). Correspondingly divided into two types of entries, including SSID class and KEY class. That is to say, each kind of configuration information in the network access configuration data is assembled into a configuration information entry.

Step 2. Each configuration information entry includes a 4-byte CRC check code, a 1-byte entry type (optional), a 2-byte entry length (optional) and a variable-length original data length.

Step 3: In each configuration information entry, encrypt the entry type, entry length, and original configuration data through the TEA encryption algorithm to obtain encrypted data.

Step 4: Use the CRC32 check algorithm to check the encrypted data to obtain the CRC check code.

Step 5. Use the encrypted data and the CRC check code to form a complete configuration information item. The structure of the assembled configuration entry is shown in Figure 2.

Assemble the entry header:

Step 1. The entry header consists of a 4-byte CRC check code and header information.

Step 2. The header information includes the version of the technical invention, the header length and the length information of each entry. These sub-information are arranged in bits from low to high.

Step 3. In order to save bits, both the version and the header length use the id index to map the real value.

Step 4. In the present invention, version 1 represents the initial version, and the header length id is 1, indicating that the header information occupies 3 bytes, totaling 24 bits.

Step 5: Calculate and obtain the length of each configuration entry.

Step 6. The version occupies 3 bits and supports 7 extensions. The header length id occupies 2 bits and supports 3 extensions. The SSID entry length occupies 6 bits, and the KEY entry length occupies 7 bits. If it is not enough, add 0 to the high bit.

Step 7: According to Step 6, obtain the data in the form of bits of each sub-information, and then reverse the order of the bits of each sub-information. Arrange the results in bits in the order of header length, version, SSID, and KEY from low to high. The header length and version information occupy the lower five bits, and SSID and KEY are filled from the 6th bit (ie bit5), which is insufficient. 32-bit high bits are filled with 0.

Step 8. The arrangement result is encapsulated into header information in the form of bytes starting from the low order. For example, as shown in Figure 3, the SSID entry length is 21 and the KEY entry length is 15 as an example:

The length of the SSID entry is 21, occupying 6 bits, 010101, and 101010 in reverse order;

The length of the KEY entry is 15, occupying 7 bits, 0001111, and 1111000 in reverse order;

The version is 1, occupying 3 bits, 001, and 100 in reverse order;

The header length id is 1, occupies 2 bits, is 01, and is 10 in reverse order;

The complete header information is (from low to high: header length id, version, SSID, KEY):

101010 1111000 100 10, if it is less than 32 bits, the high bits are filled with 0 bits:

000000 101010 1111000 100 10--》00000010 10101111 00010010

Converted to byte form from low order: 12 5e 02.

Step 9. Perform CRC32 check on the header information to obtain a 4-byte CRC check code.

In step 10, the CRC check code and the header information form the completed entry header. The structure of the entry header is shown in Figure 4.

Package configuration header (referred to as header):

The packet header includes: private preamble, CRC32 check code, packet body length, packet type and a 3-byte reserved field.

Private preamble: Stores the frame identifier, which can be a 4-byte special hexadecimal number, and the implementer negotiates to determine the unified value.

CRC check code: The CRC32 check code of the subsequent data of the packet header of the length specified by the length of the packet body.

Body length: the sum of the length of the entry header and each entry.

Packet type: 0, indicating configuration data for Beacon. Scalable.

Reserved field: Reserved.

During the transmission process, the private preamble and CRC check code of the packet header need to be converted to the network byte order, and other data may not be converted. The data structure of the packet header is shown in Figure 5.

The configuration header, entry header, and each entry information form a complete data segment, loaded into the vendor-specific field of the Beacon, and sent out with the Beacon broadcast.

In another embodiment of the present invention, after the step of broadcasting the beacon frame carrying the network access configuration data and the frame identifier, the method further includes:

Record the device information of the devices successfully connected to the network;

After the password of the wireless access point is changed, a probe request frame sent by the device is received, and device information and access point information are obtained from the vendor-specific information field of the probe request frame;

Compare the obtained access point information with the local access point information;

When the comparison is consistent, match the acquired device information with the recorded device information;

When the matching is successful, after the new network access configuration data is loaded into the vendor-specific information field of the beacon frame, the beacon frame loaded with the new network access configuration data is broadcast.

The device information may select the device MAC address, and the access point information may select the access point MAC address.

The embodiment of the present invention can ensure that when the AP changes the network access configuration data, only the AP and the intelligent IoT device are required to participate, which reduces the dependence on the third-party control program, simplifies the device configuration network access process, and optimizes the user experience.

Of course, this embodiment can also be implemented independently of the above-mentioned embodiment and each variant embodiment, that is to say, the embodiment of the present invention also provides a device network access configuration method, which is used for a wireless access point. The method includes the following steps:

Step 1, record the device information of the device successfully connected to the network;

Step 2, after the password of the wireless access point is changed, the detection request frame sent by the device is received, and the device information and the access point information are obtained from the manufacturer-specific information field of the detection request frame;

Step 3, compare the obtained access point information with the local access point information;

Step 4, when the comparison is consistent, match the acquired device information with the recorded device information;

Step 5: When the matching is successful, after the new network access configuration data is loaded into the vendor-specific information field of the beacon frame, the beacon frame loaded with the new network access configuration data is broadcast.

S602, obtaining the network access configuration data from the vendor-specific information field of the beacon frame;

S603, access the network based on the acquired network access configuration data.

In an embodiment of the present invention, before the step of acquiring the network access configuration data from the vendor-specific information field of the beacon frame, the method further includes:

Searching from the vendor-specific information field of the beacon frame for a frame identifier used to identify the network access configuration data carried by the beacon frame;

When the frame identifier is searched, the network access configuration data is acquired from the vendor-specific information field.

Further, the step of acquiring the network access configuration data from the vendor-specific information field; the step of accessing the network based on the acquired network access configuration data includes:

obtaining the network access configuration data from the vendor-specific information field of the beacon frame;

If the network access configuration data includes two types of configuration information, a network access password and a service set identifier, access the network based on the network access password and the service set identifier;

If the network access configuration data includes configuration information such as a network access password, the service set identifier is obtained from the SSID field of the beacon frame, and the network is accessed based on the network access password and the service set identifier.

Describing the embodiment of the present invention in detail, after receiving the beacon frame, the device starts to search the manufacturer-specific information field, firstly searches the packet header, and when the beacon frame is searched, based on the packet information in the packet header and the entry header Header information, corresponding configuration information is obtained from each configuration entry; the header information at least includes length information of each configuration entry, and the packet information at least includes configuration data packet length information.

Specifically, the configuration packet header includes a private preamble, a packet information check code and packet information; the frame identifier is specifically the private preamble; the entry header includes a header information check code and header information; The configuration entry includes the configuration entry check code and the corresponding configuration information;

The step of acquiring corresponding configuration information from each configuration entry based on the packet information in the packet header and the header information in the entry header specifically includes:

Verifying the packet information check code, and extracting the packet information after the verification of the packet information check code is passed;

Verifying the header information check code, and extracting the header information after the verification of the header information check code is passed;

The entry check codes of the configuration entries are respectively verified, and after all the entry check codes are verified, the location of the configuration information is determined according to the packet information and the header information, and corresponding configuration information is extracted from the determined location.

As shown in FIG. 7 , in another embodiment of the present invention, in another embodiment of the present invention, after the step of accessing the network based on the acquired network access configuration data, the method further includes:

When the wireless access point is disconnected due to a wrong password, loading the local device information and the access point information into the vendor-specific information field of the probe request frame;

Turn on the configuration state, receive a beacon frame that carries new network access configuration data broadcast by the wireless access point, and obtain new network access configuration data from the vendor-specific information field of the beacon frame;

The data access network is based on the new network access configuration.

Wherein, the device information includes the MAC address of the device; the access point information includes the MAC address of the access point.

Of course, the detection method shown in FIG. 7 can also be implemented independently of the network access configuration method shown in FIG. 6 .

A specific application example is given to describe the method in the embodiment of the present invention in detail.

1. After the smart IoT device is configured, it receives Beacon messages over the air.

2. After receiving the Beacon packet, firstly search for the private preamble contained in the packet header. Because the vendor-specific fields often have a packet tail, it is recommended to search from the packet tail in reverse order.

3. After searching for the private preamble, extract the packet header from the location. Verify that the CRC check code of the entire configuration data is correct. Incorrectly discard the packet.

4. After the CRC verification is correct, check whether the packet type is the Beacon configuration data. If not, discard the packet.

5. After the packet header verification is completed, the entry header information is extracted from the subsequent data of the packet header.

6. The first four bytes of the entry header information are the CRC check code. Since the header information in the entry header is up to 6 bytes and at least 2 bytes, starting from 2 bytes, the CRC check value of the data of this length is gradually calculated, starting with the received entry header information. If the four-byte CRC value is compared, the length of the header information can be determined if they are consistent.

7. Parse the header length ID, version and the length of each entry from the header information. When the version value is 1, the version occupies 3 bits, the header length ID occupies 2 bits, the SSID information occupies 6 bits, and the KEY occupies 7 bits. Arranged in the order of header length ID, version, SSID, and KEY.

8. Starting from the first byte of the header information, reverse the order of the lower 2 bits of the byte, which is the header length ID. Verify whether the header length of the header length ID mapping is consistent with the length value obtained in step 6, and discard if inconsistent.

9. After verifying the length of the header, start from the next bit in the original data, and follow the lower three bits in reverse order, which is the version.

10. The lower 6 bits of the subsequent version are the SSID, and the insufficient bits are filled from the lower bits of the next byte. Reverse the 6-bit order to get the length of the SSID entry.

11. The subsequent lower 7 bits of the SSID are KEY, which is insufficient to fill in the lower bits of the next byte. Reverse the order of the 7-bit bits to obtain the length of the KEY.

12. After verifying the header entry, start parsing the information in each configuration entry.

13. From the starting position of the configuration entry, take the data of the SSID length as the SSID entry. The first four bytes are the CRC check value. First, obtain the CRC check value of the remaining data in the SSID entry to verify whether it is correct. If it is not correct, the packet is discarded. If correct, the subsequent data is decrypted by TEA. The entry type and entry length fields, if present, are verified to be correct. The rest of the data is the SSID.

14. After verifying the SSID data, starting from the next byte, take the data of the KEY length as the KEY entry. The first four bytes are the CRC check value. First, obtain the CRC check value of the remaining data in the KEY entry to verify whether it is correct. If it is not correct, the packet is discarded. If correct, the subsequent data is decrypted by TEA. The entry type and entry length fields, if present, are verified to be correct. The rest of the data is the SSID.

15. After obtaining the SSID and KEY, the smart IoT device connects to the network through this value.
