In addition, numerous specific details are set forth in the following description in order to provide a better illustration of the invention. It will be understood by those skilled in the art that the present invention may be practiced without some of these specific details. In some instances, well known methods, procedures, and components have not been described in detail so as not to obscure the present invention.
Example 1
Fig. 1 shows a typical application scenario of a configuration method of a wireless network, where as shown in fig. 1, an intelligent terminal, such as a mobile phone 10, establishes a wireless network connection with a router 20 and obtains configuration information of the wireless network, such as a service set identifier SSID, a basic service set identifier BSSID, a password, etc. of the wireless network, and sends a probe request carrying the configuration information to the wireless network, and other wireless network devices 30 in the wireless network environment and in a listening state can obtain the configuration information of the wireless network by receiving the probe request and join the wireless network.
Therefore, the configuration information of the wireless network is sent by the intelligent terminal, the problem that the wireless network equipment cannot acquire or input the configuration information of the wireless network in an independent state can be solved, the step that network configuration can be performed only through wired connection is saved, and automatic and efficient wireless network configuration is realized.
Fig. 2 shows a flow chart of a method of configuring a wireless network according to one embodiment of the invention. As shown in fig. 2, the method mainly includes:
step S21, the mobile phone 10 encodes and encrypts the configuration information of the wireless network.
First, before performing step S21, the handset 10 needs to first establish a connection with the router 20 of the wireless network and acquire configuration information of the wireless network, including, but not limited to, a service set identifier SSID, a basic service set identifier BSSID, and a password of the wireless network.
In this step, the configuration information of the wireless network is encoded, and when the configuration information of the wireless network includes a password of the wireless network, the password may be encoded in a manner of keeping the number of bits of the password unchanged, for example, in a manner of keeping the original text of the password unchanged, or may be reorganized to encode on the premise of keeping the number of bits of the password unchanged. Generally, the number of bits of data is increased during encoding, but the present invention encodes in a manner that the number of cipher bits is kept unchanged, so that the number of data packets required to be transmitted in the subsequent steps can be reduced to the greatest extent, thereby improving efficiency.
When the configuration information of the wireless network includes a service set identifier SSID of the wireless network, the service set identifier SSID may be divided into one or more data sets according to a first predetermined number of bits, each data set is complemented with 8 bits to form an ASCII code of one byte, and a first pair of modulation is performed on a second predetermined bit in the ASCII code, so as to implement encoding of the service set identifier SSID.
For example, service set identification SSID data is arranged in binary, from high order to low order, every 6 bits are fetched as one data set, and 01 is appended to the highest two bits of each data set to form one byte ASCII code, and so on, SSID data of every 3 bytes (24 bits) is divided into 4 data sets, and is represented by 4 ASCII codes after 01 is appended to the high order. And when the last original data is less than 6 bits after being encoded, the high-order filling and the low-order zero filling close to 6 bits in the last encoded ASCII code data can be realized, and the encoded data are ASCII codes.
In addition, the encoding step may further include performing a swap process on the upper 4 bits of the adjacent two bytes, for example: assuming that the data to be processed is 0x12,0x34,0x45,0xab, the data after the exchange processing is 0x32,0x14,0xa5,0x4b.
In one possible implementation, there are two cases where special handling is required for this step: if the transmitted data is odd, the last byte is not exchanged; if any one of the data low 4 bits in a group that needs to be swapped is F, then the group does not make a swap.
In a possible implementation manner, the configuration information of the wireless network further includes a basic service set identifier BSSID or other data, and the basic service set identifier BSSID or other data may also be encoded according to the same rule as the service set identifier SSID, which is not described herein.
In this step, the configuration information of the wireless network is encrypted, and in one possible implementation, the configuration information subjected to the above encoding process may be encrypted by a first predetermined formula, for example, formula (1).
Fig. 3 schematically shows a process of encrypting data according to formula (1), where the original data is a and the encrypted data is A1 as shown in fig. 3.
If(A&0xF＜＝7)
A1＝A+A&0xF
Else if(7＜A&0Xf＜＝F)
A1＝A-(F-A&0xF) (1)
And S22, writing the configuration information of the encoded and encrypted wireless network into the effective data of the data packet in a mode of 1 byte corresponding to 1 byte, and writing the data packet into a service set identification SSID field in a Probe Request frame.
In this step, the configuration information of the wireless network after encoding and encryption needs to be written into a data packet, and fig. 4 shows an organization form of the data packet in the embodiment of the present invention, and as shown in fig. 4, the data packet includes: the total packet number, the sequence number of the packet, the data type of the packet, the lengths 1-6, the effective data and the CRC check bit, and the data packet can also comprise a channel.
In one possible implementation, the channel may occupy 1 byte, with the upper two bits fixed to 01 and the lower 6 bits representing the WLAN channel in which the device is located. The total number of packets may occupy 1 byte, with the highest two bits of each byte fixed to 01 and the lower 6 bits indicating that the current communication needs to be completed by a data packet defined by a few packet book format. The number of the packet can occupy 1 byte, the highest 2 bits are fixed to be 01, the lower 6 is the number of the packet, the value range is 0-63, and the number of the packet in the total number of the current communication packets is indicated. The packet type may occupy 1 byte, the highest 2 bits are fixed to 01, the lower 6 bits represent the type of data contained in the packet, wherein 000001 represents a network password KEY, 000010 represents a BSSID, 000100 represents an SSID, 001000 ～ 100000 represents a Reserved type Reserved, and in addition, each packet may contain one or several data types. The length occupies 6 bytes at most, which means that each type of data contained in the packet corresponds to one byte in the length information, if only one type exists, the length only needs one byte, if two types exist, the length only needs two bytes, and the like, the highest two bits of each byte are fixed to be 01, the length byte order has a corresponding relation with the types, and the number of the length bytes corresponding to the low-order type can be the front. The effective data has uncertain length, and is segmented according to types and lengths, and each segment corresponds to each type of effective data. The CRC check bit occupies 2 bytes, CRC8 calculation mode is adopted to carry out CRC check on the content of the data packet (before the first byte of CRC), the same algorithm is used to calculate the content of the data packet (before the second byte of CRC) after the calculation is completed, and after the CRC of two bytes is calculated, the lower 6 bits are added with decimal 63, and the corresponding byte bits are filled.
In this step, the encoded and encrypted wireless network configuration information is written into the effective data of the data packet in a manner of 1 byte to 1 byte, specifically, each byte of wireless network configuration information occupies one byte in the effective data when the effective data of the data packet is written, and compared with the common writing manner that 1 byte of data occupies multiple bytes of effective data, the embodiment of the invention can reduce the number of the data packets to the greatest extent so as to improve the efficiency of transmitting the data packet.
In addition, the embodiment of the invention uses the SSID field in the Probe request frame to transmit the data packet, and the SSID field in the Probe request frame is defined by three pieces of information in the IEEE802.11 protocol: SSID field, SSID length, and SSID content. Wherein the SSID field identifier is used for indicating that the field is an SSID; the SSID length is the length of a character string for identifying the SSID contained in the field, and the maximum value thereof is 32; SSID content is used to identify the name of the network, which is a maximum of 32 characters.
In this embodiment, the SSID field in the Probe request frame is modified to carry a data packet, where the SSID field identifier remains unchanged, the SSID length identifies the length of the SSID content, and 32 bytes of the SSID content are used to carry the data packet, so that one data packet is a maximum of 32 bytes, where the number of bytes remaining except for the overhead length of the data packet is a number of bytes of valid data, and is a maximum of 26 bytes, and the overhead length of the data packet=the number of channels+the number of packets+the sequence number+the type+the data length field+the CRC.
In one possible implementation, the sum of the SSID and the password of the wireless network may reach 96 bytes, and in the case that the valid data of one data packet is 26 bytes, the quotient obtained by dividing 96 bytes by 26 bytes may be rounded according to 3.69 carry, that is, the SSID and the password of the wireless network are divided into 4 data packets and stored in the SSID field in the Probe request frame, in other words, the Probe request includes 4 Probe request frames to carry network configuration information.
Step S23, a Probe Request is sent to the wireless network, wherein the Probe Request comprises the Probe Request frame.
The intelligent terminal sends a Probe Request to the wireless network, wherein the Probe Request comprises a Probe Request frame carrying wireless network configuration information.
Step S24, the wireless network equipment enters a monitoring mode, wherein the monitoring mode allows a probe request sent by the intelligent terminal to be received. This step is not limited to being performed after step S23, and the wireless network device may start the listening mode at any time period after being powered on.
Step S25, a Probe Request is received, wherein the Probe Request comprises a Probe Request frame, and a data packet in a Service Set Identification (SSID) field in the Probe Request frame is acquired. The wireless network device extracts the corresponding data length field according to the packet type field, calculates the total length of the data, compares the data length with the length of the SSID field in the Probe request frame after the overhead length of the data packet judged according to the type field is added, if the data length of the data packet is equal to the SSID field in the Probe request frame, the data length of the data packet is indicated to be the frame to be received, CRC (cyclic redundancy check) is carried out after the data frame is received, and if the data length of the data packet is correct, the data frame is reserved, otherwise, the data frame is discarded.
And step S26, organizing the data packet according to the total packet number and the packet sequence number in the data packet. The method comprises the steps of extracting effective data in a data packet, and organizing the extracted effective data together according to the total number of the data packet and the sequence number of the data packet.
And step S27, decrypting and decoding the data packet to obtain the configuration information of the wireless network.
The decryption process in this step is the inverse of the encryption process shown in fig. 3, and may be performed, for example, by using the inverse algorithm formula (2) of the above formula (1), assuming that the encrypted data is A1 and the decrypted data is a.
if((A1&0xF)％2＝＝0)
A＝(A1+(A1&0xF0))/2；
Else if(((A1&0xF)％2＝＝1))
A= (a1+ (a1 &0xF 0) +0 xF)/2 formula (2)
The decoding in this step is the inverse of the encoding process in step S21, and in one possible implementation, the number of bits of the decoded data is kept unchanged for the network password in this embodiment. In another possible implementation manner, for SSID, BSSID and other data, a first specific bit in the decrypted data may be obtained to form an ASCII code, and a second specific bit in the ASCII code is subjected to a second exchange process, where the first specific bit corresponds to a first predetermined bit in the encoding process, and the second specific bit corresponds to a second predetermined bit in the encoding process, specifically, the method may include arranging the data in binary, from high order to low order, taking out the low 6 bits from each byte, if it is determined that the last original data is less than 6 bits after encoding, removing 0 complementary to the encoding process, and so on, and then starting from the highest order, forming one data every 8 bits, and so on. The second pair of pairs is the inverse of the first pair of pairs in the encoding step, e.g., the upper 4 pairs of adjacent 2 bytes, and if the decoded data is 0x32,0x14,0x a5,0x4b, the data is 0x12,0x34,0x45,0x ab after this step.
This step may also include two special handling cases: if the transmitted data is odd, the last byte is not exchanged; if any one of the data low 4 bits in a group that needs to be swapped is F, then the group is not swapped.
And step S28, connecting the wireless network according to the configuration information of the wireless network.
The wireless network device 30 connects to the wireless network according to the configuration information of the wireless network.
Therefore, the configuration information of the wireless network is sent by the intelligent terminal, the problem that the wireless network equipment cannot acquire the configuration information of the wireless network in an independent state can be solved, the step that network configuration can be performed only through wired connection is saved, and automatic and efficient wireless network configuration is realized.
In addition, the number of bytes required for transmitting the wireless network configuration information can be minimized by encoding and encrypting the password in a mode of keeping the number of the password bits unchanged, and the number of the data packets required for transmitting the wireless network configuration information can be reduced by writing the wireless network configuration information into the effective data of the data packets in a mode of 1 byte corresponding to 1 byte and forming a probe request.
