Method and apparatus for establishing SSID-based connection between terminal device and gateway device
View Patent ↗The present application provides a method for interconnection between a terminal device and a gateway device. When the terminal device detects that the terminal device and the gateway device meet a first connection condition and that it is the first time the terminal device is to be connected to the gateway device, acquiring, from the gateway device, a first common SSID preset in the gateway device; and when authentication performed by the terminal device on the acquired first common SSID succeeds, sending a second common SSID preset in the terminal device to the gateway device, so that when authentication performed by the gateway device on the second common SSID succeeds, a common SSID-based connection is established between the terminal device and the gateway device. So using the method, processing of interconnection between a terminal device and a gateway device takes a short time and a process is relatively simple.

sending, by the terminal device, a second common SSID that is preset in the terminal device after authentication performed on the first common SSID succeeds;
establishing a common SSID-based connection between the terminal device and the gateway device, when authentication performed by the gateway device on the second common SSID succeeds;
receiving, by the terminal device from the gateway device, a private SSID and a key of the gateway device;
disconnecting, by the terminal device, the common SSID-based connection between the terminal device and the gateway device;
sending, by the terminal device, the private SSID and the key to the gateway device; and
establishing a private SSID-based connection between the gateway device and the terminal device, when authentication performed by the gateway device on the received private SSID and key succeeds.
