Abstract: In a human-computer interaction method, a second electronic device receives a first picture and identification information of at least one application that are sent by a first electronic device based on a first operation. The second electronic device displays the first picture and an icon of the at least one application. The second electronic device receives a second operation performed on a first icon, where the first icon is one icon in the icon of the at least one application. In response to the second operation, content of an application window of a first application displayed by the second electronic device is the same as that of an application window of the first application opened on a first interface.

Abstract: Embodiments of the present invention relate to communications technologies and disclose a method and a system for establishing a data transmission channel, a SIP server, and a session border controller. A first authentication request message is sent by a first terminal. The first authentication request message includes identifier information of the first terminal and identity information of a second terminal. It is determined that the identifier information of the first terminal matches pre-stored authentication information of the first terminal. According to the identity information of the second terminal, a second authentication request message that carries authentication information of the second terminal is sent to the second terminal. After receiving an authentication success response message from the second terminal, a data transmission channel is established between the first terminal and the second terminal.
