Method for establishing hotspot connection and terminal device

A terminal device, wherein the terminal device is a first terminal device, and the first terminal device comprises a memory, a processor, an input unit, and a wireless communications interface, wherein

• the memory is configured to store a program instruction;
• and
• when the program instruction is processed by the processor, the first terminal device is caused to perform the steps of:
• receiving a first operation, wherein the first operation allows one or more other devices to use mobile data of the first terminal device;
• broadcasting a first broadcast frame, wherein the first broadcast frame is used to detect a second terminal device capable of being connected to the first terminal device and using a wireless local area network (WLAN) hotspot of the first terminal device, and the first broadcast frame instructs the second terminal device to broadcast a second broadcast frame in response to determining the second terminal device is capable of being connected to the first terminal device and using the WLAN hotspot of the first terminal device based on the first broadcast frame;
• receiving the second broadcast frame from the second terminal device, wherein the second broadcast frame comprises information indicating the second terminal device is capable of being connected to the first terminal device and using the WLAN hotspot of the first terminal device;
• determining to share the WLAN hotspot with the second terminal device based on the received second broadcast frame;
• in response to determining to share the WLAN hotspot with the second terminal based on the received second broadcast frame, requesting that the second terminal device use the first terminal device as a hotspot and sending WLAN hotspot connection information for using the first terminal device as the hotspot, the WLAN hotspot connection information being sent directly to the second terminal device by way of a Bluetooth low energy (BLE) channel, wherein WLAN hotspot connection information comprises a password for accessing the WLAN hotspot;
• establishing a WLAN hotspot connection to the second terminal device by directly using the WLAN hotspot connection information without the password for accessing the WLAN hotspot being inputted into the second terminal device;
• and
• connecting the second terminal device to the Internet by using the WLAN hotspot of the first terminal device.
