[0072] In an implementation of this embodiment, controlling the mobile terminal to perform TV hotspot connection, Miracast screen projection or router WIFI connection according to the selected mode and the WIFI information in the WIFI information transmission packet specifically includes:

[0073] If the selected mode is the TV hotspot connection mode, control the mobile terminal to connect to the TV hotspot according to the WIFI name, WIFI password and WIFI encryption type corresponding to the TV hotspot connection mode in the WIFI information transmission packet;

[0074] The TV establishes a socket connection with the mobile terminal, receives the TV key corresponding to the current date and time in the WIFI information transmission packet sent by the mobile terminal, performs TV hotspot connection request authentication according to the TV key, and determines whether the TV key is correct;

[0075] If the TV key is correct, the TV hotspot connection request is approved, and the network access permission is granted to the mobile terminal;
