Methods and devices of accessing wireless network

A method of accessing a target wireless network provided by a wireless AP device, the method applied to a target terminal device and comprising:

• broadcasting a beacon packet in a preset time period, wherein the beacon packet carries terminal device information of a second terminal device in an AP mode;
• receiving a verification packet from a first terminal, wherein the first terminal sends the verification packet to the second terminal device in the AP mode according to the terminal device information;
• sending a response packet to the first terminal, so that the first terminal device:
• detects a recorded history terminal device list according to the terminal device information of a second terminal device which sends the response packet, wherein the recorded history terminal device list contains terminal device information of a terminal device found by the first terminal device previously and accesses the target wireless network;
• and
• determines a second terminal device corresponding to the terminal device information found from the history terminal device information as the target terminal device;
• receiving a physical layer packet carrying a multicast packet sent from a first terminal device that has accessed a target wireless network, wherein a multicast address of the multicast packet is one of a plurality of multicast addresses constructed by the first terminal device according to access information of the target wireless network;
• acquiring a MAC address of the physical layer packet;
• acquiring a data area in the MAC address corresponding to the multicast address sent from the first terminal device according to a mapping relationship between the MAC address and the multicast address;
• reading a value byte in the data area of the MAC address to obtain a byte content, and reading an index byte in the data area of the MAC address to obtain location information of the byte content;
• combining the byte content according to the location information to obtain an encrypted character string;
• and
• decoding the encrypted character string to obtain a SSID and a password of the target wireless network as the access information;
• and
• accessing the target wireless network according to the access information.

A first terminal device, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to perform:
• accessing a target wireless network provided by a wireless AP device;
• receiving at least one beacon packet broadcasted by a second terminal device in an AP mode in a preset time period by calling a wireless AP scan interface, wherein the beacon packet carries terminal device information of the second terminal device;
• acquiring a target terminal device from the second terminal device in the AP mode according to the terminal device information, wherein acquiring the target terminal device from the second terminal device in the AP mode according to the terminal device information comprises:
• sending a verification packet to the second terminal device in the AP mode according to the terminal device information;
• receiving a response packet of the verification packet from the second terminal device;
• detecting a recorded history terminal device list according to the terminal device information of the second terminal device which sends the response packet, wherein the recorded history terminal device list contains terminal device information of a terminal device found by the first terminal device previously and accesses the target wireless network;
• and
• determining the second terminal device corresponding to the terminal device information found from the history terminal device information as the target terminal device;
• encrypting the access information of the target wireless network to acquire an encrypted character string, wherein the access information comprises a service set identifier SSID and a password of the target wireless network;
• constructing a plurality of destination media access control MAC addresses according to the encrypted character string, wherein the destination MAC address is used to carry information of the encrypted character string;
• generating a plurality of multicast addresses for the plurality of destination MAC addresses according to a mapping relationship between the MAC address and the multicast address;
• and
• sending a multicast packet to each of the plurality of multicast addresses, wherein the multicast packet is indicative of the access information and is received by the target terminal device so as to access the target wireless network.
