in this embodiment of the present application, the step of generating a distribution network data packet by a first device (the first device is in a distribution network process), includes: an identification phase and a data phase; the first device circularly switches work in the identification phase and the data phase. A network distribution packet comprising: the second distribution network data packet generated in the identification phase, the first distribution network data packet generated in the data phase and the third distribution network data packet generated in the data phase. The first distribution network data packet carries distribution network information of the access point AP, the second distribution network data packet carries first identification information, and the third distribution network data packet carries second identification information.

In the identification phase, the first device generates a second distribution network data packet, including:

s4201: in the identification phase, the first device encodes first identification information into the length information.

The first identification information includes: and the access point AP hides the information of the service set identifier SSID and the version number of the distribution network protocol between the first device and the second device.

Specifically, the first device may encode the first identification information into a designated position of the length information, where the designated position of the length information is different for different first identification information.

If the information of whether the SSID is hidden by the access point AP indicates that the SSID is hidden by the access point AP, the distribution network data packet needs to carry the SSID of the access point AP; and if the SSID hiding information of the access point AP indicates that the SSID is not hidden by the access point AP, the SSID of the access point AP is not carried in a distribution network data packet.

In the identification phase, the BSSID (Basic Service Set Identifier) of the AP may be encoded in a BSSID field of a WiFi MAC (Medium Access Control Sub Layer) header of a second distribution network packet.

The WiFi packet length of the second distribution network data packet generated in the identification stage is a first preset value; and the access code AC information of the second distribution network data packet generated in the identification stage is a second preset value.

The QoS information of the distribution network data packet comprises: access code AC information; the AC (Access Code) information is obtained by mapping according to a TID (Traffic Identifier) field in a QoS Control field of a WiFi MAC header, where the length of the AC information of the Access Code is fixed to 2 bits, which is the prior art and is not described herein again.

Please refer to fig. 5, fig. 5 is a mapping table of TID field and AC information in QoS Control field, where the length of TID field in fig. 5 is 3bit and the length of AC information is 2bit. The length of the length information may be determined according to information carried by the generated distribution network data packet, such as: and determining according to the distribution network information carried by the first distribution network data packet so as to reduce the length of the length information on the basis of carrying complete distribution network information.

Q second distribution network data packets can be generated in the identification stage, wherein Q is a positive integer; the second preset value may be set to different values for different second distribution network packets, such as: q =4, the second preset values of the consecutive 4 second distribution network packets may be 2b '00 (00), 2b'01 (01), 2b '10 (10), 2b'11 (11) in sequence.

Referring to fig. 6, fig. 6 is a schematic diagram of a second distribution network data packet generated at an identification stage according to an embodiment of the present application, where Q =4 in fig. 6, fig. 6 shows AC information and length information of the second distribution network data packet, AC [1] and AC [0] represent access code AC information of the second distribution network data packet with 2 bits, LEN [8] to LEN [0] represent length information of the second distribution network data packet, that is, the length information of the second distribution network data packet is 9 bits.

Specifically, LEN [6] (specified position) in fig. 6 is used to record information whether the SSID is hidden by the access point AP, such as: a LEN [6] of 1 indicates that the SSID is hidden by the AP, a LEN [6] of 0 indicates that the SSID is not hidden by the AP, or a LEN [6] of 0 indicates that the SSID is hidden by the AP, a LEN [6] of 1 indicates that the SSID is not hidden by the AP, and a LEN [6] of 1 in fig. 6 indicates that the SSID is hidden by the AP.

LEN [7] (location specified) in fig. 6 is used to record the version number of the distribution network protocol between the first device and the second device, and LEN [7] of fig. 6 is 0, which means that the version number of the distribution network protocol between the first device and the second device is 0 (1b' 0). In FIG. 6, LEN [8] is 1 (1b' 1) at the identification stage. In fig. 6, the 4 second distribution network data packets correspond to different second preset values, and the length information of the 4 second distribution network data packets is the same.

It should be noted that, the WiFi packet length and the WiFi packet length information are different concepts, the WiFi packet length refers to the length of the WiFi packet, that is, the length of the network configuration data packet, and the WiFi packet length information refers to the length information carried by the WiFi packet, that is, the length information of the network configuration data packet, for example: as shown in fig. 6, the WiFi packet length of the second distribution network packet is OFFSET +256[ +64], and the WiFi packet length information of the second distribution network packet is information recorded from LEN [8] to LEN [0 ]. Wherein [ +64] in the OFFSET +256[ +64] refers to the length of the length information of the second distribution network packet occupied by the information of whether the access point AP hides the service set identifier SSID.

Specifically, the information of whether the SSID is hidden by the access point AP is encoded into LEN [6] in fig. 6, if LEN [6] is 1, that is, the SSID is hidden by the access point AP, at this time, the WiFi packet length of one second distribution network data packet in fig. 6 is OFFSET +256+64, that is, OFFSET +320; if LEN [6] is 0, that is, the SSID is not hidden by the access point AP, at this time, the WiFi packet length of a second distribution network packet in fig. 6 is OFFSET +256.

Wherein, the OFFSET represents the data OFFSET of the distribution network data packet; the OFFSET is fixed in size, and the size of the OFFSET is related to the encryption mode of the distribution network data packet and whether QoS is available. The second device may calculate the OFFSET according to the encryption mode and the QoS information of the distribution network data packet after receiving the distribution network data packet, which is the prior art and is not described herein again. And the second equipment calculates the OFFSET of the second distribution network data packet, and the OFFSET is subtracted from all the subsequent distribution network data packets to obtain the WiFi packet length information of the distribution network data packets.

S4202: in the identification phase, the first device generates a second distribution network data packet.

The WiFi packet length information of the second distribution network data packet is the length information obtained by encoding in step S4201. The second distribution network data packet is generated according to a WiFi transmission protocol.

s4211: in the data phase, the first equipment encodes the distribution network information of the access point AP into length information and QoS information;

the quality of service QoS information includes: access code AC information; and the access code AC information is obtained by mapping a data form identification code TID field in a QoS Control field of the WiFi MAC packet header. The description of the QoS information refers to step S4201, which is not described herein.

In this embodiment of the application, encoding the distribution network information of the AP to length information and QoS information includes:

and in the data phase, encoding the distribution network information of the access point AP into length information and access code AC information.

Specifically, the distribution network information of the access point AP may be encoded into a first preset position of the length information and the access code AC information, where the first preset position may occupy all information positions of the length information and the access code AC information, or may occupy part information positions of the length information and the access code AC information. The first preset position may be set according to an actual length of the distribution network information or a coding mode, which is not limited herein.

In this embodiment, the distribution network information includes: the password of the access point AP and the verification information of the service set identification SSID of the access point AP are obtained, and the verification information of the service set identification SSID of the access point AP comprises CRC5 (cyclic redundancy check code) of the SSID. If the access point AP hides the service set identifier SSID, the distribution network information further includes: and the service set identification SSID of the access point AP.

Specifically, the distribution network information of the access point AP may be sequentially divided to obtain M data segments, where M is a positive integer; each data segment contains N characters, N being a positive integer, such as N =4; and respectively and sequentially generating N first distribution network data packets according to the N characters contained in the data section.

Specifically, each character is encoded into length information and access code AC information, the WiFi packet header length information is generated to be the length information obtained through encoding, and the access code AC information is a first distribution network data packet of the AC information obtained through encoding. If the last data Segment has no N characters, the verification information (CRC 5) of the SSID of the access point AP may be copied to fill up the N characters.

The character value range of the password which is coded into the first distribution network data packet and used for representing the access point AP is different from the character value range of the verification information which is coded into the first distribution network data packet and used for representing the SSID of the access point AP, so that the first distribution network data packet carrying the password of the access point AP and the first distribution network data packet carrying the verification information of the SSID of the access point AP can be effectively distinguished.

Corresponding distinguishing information can also be encoded into the length information and/or the AC information to distinguish various distribution network data packets, such as: and distinguishing the first distribution network data packet carrying the password of the access point AP, the first distribution network data packet carrying the verification information of the SSID of the access point AP and the first distribution network data packet carrying the SSID of the access point AP, and the like, wherein the limitation from the corresponding difference information of the codes to the length information and/or the AC information is not made. Other methods may also be used to encode the distribution network information and the related information (for example, the distinguishing information) of the access point AP into the length information and the AC information, and the method of encoding the distribution network information of the access point AP into the length information and the AC information is not limited herein.
