In addition, the same network protocol is supported between the first terminal and the second terminal to realize the communication connection between the first terminal and the second terminal, wherein the network protocol includes but is not limited to IEEE802.11 protocol.
It can be understood that, in the embodiment of the present invention, the first terminal and the second terminal are distinguished by names according to different roles in network extension, and corresponding hardware devices may be the same or different, as long as the technical solutions of network extension of the first terminal and the second terminal in the embodiment of the present invention can be respectively implemented.
Fig. 2 is a flowchart of a first embodiment of a method for network extension provided by the present invention, fig. 3 is a signaling flowchart of the first embodiment of the method for network extension provided by the present invention, and an execution subject of the present embodiment may be a first terminal. As shown in fig. 2 and 3, the method of the present embodiment includes:
s21: receiving a first message, wherein the first message comprises a network extension request of at least one second terminal, and the network extension request comprises a device identifier and an access parameter of the corresponding second terminal.
Specifically, the first terminal receives a first message, where the first message may include network extension requests of a plurality of second terminals, and a network extension request of each second terminal may include a device identifier of the second terminal and an access parameter of the second terminal.

S22: and generating an access instruction of the at least one second terminal according to a preset encryption algorithm and the network expansion request, and broadcasting the access instruction.
Specifically, after receiving the first message, the first terminal encrypts the network expansion request of the second terminal by using a preset encryption algorithm to generate an access instruction. When the first terminal performs encryption processing, in an optional implementation manner, after the first message is analyzed to obtain network extension requests of N second terminals, the network extension requests of each second terminal are respectively encrypted to generate an access instruction, and finally N access instructions are obtained for broadcasting; another optional embodiment is to analyze the first message to obtain network extension requests of N second terminals, encrypt the network extension requests of the N second terminals according to a preset encryption algorithm, and combine the N encryption results into one access instruction for broadcasting, which is not specifically limited in the present invention.

After receiving the access instruction broadcasted by the first terminal, the second terminal decrypts the access instruction according to a preset decryption algorithm, the device identifier and the access parameter of the second terminal, if the decryption is successful, the authentication of the first terminal and the second terminal is successful, and the second terminal can expand the network of the first terminal, so that the second terminal sends a network connection request to the first terminal.
