Abstract: Implementations relating to service information communication methods and electronic devices are provided. One method includes: communicating, by a terminal device based on token information, first service information of a first service with an Internet of things (IOT) server corresponding to the first service, wherein the token information is obtained from the IoT server by the terminal device after performing authentication with the IoT server based on user information of the terminal device, and wherein the token information is used by the terminal device to communicate with the IoT server, and communicating, by the terminal device, second service information of the first service with an IoT terminal device corresponding to the first service, wherein the second service information is associated with the first service information, and wherein the user information of the terminal device is same as user information of the IoT terminal device.

Abstract: A screen sharing method and system and an electronic device are provided. The screen sharing system may include a first electronic device, a second electronic device, a third electronic device, and a fourth electronic device. The third electronic device may be an electronic device near the first electronic device. The fourth electronic device may be an electronic device near the second electronic device. In the method, the first electronic device may establish a video communication connection to the second electronic device. The third electronic device may share a screen of the third electronic device with the second electronic device by using the first electronic device. The second electronic device may display the screen shared by the third electronic device, and may further switch the screen shared by the third electronic device to the fourth electronic device for display.
