Abstract: Embodiments of the present disclosure provide a method and a device for establishing a channel, capable of reducing data transmission path length when two WEBRTC terminals transmit data based on an IMS network, reducing network delays, and reducing load of a media gateway device. The method includes: receiving, by a WEBRTC signaling gateway device, a session request message transmitted by a WEBRTC terminal serving as a calling terminal, where the session request message comprises an identifier of a called terminal, determining that the called terminal is a WEBRTC terminal according to the access mode in which the called terminal accesses a WEBRTC signaling terminal, and transmitting the session request message to the called terminal via the WEBRTC signaling gateway device accessed by the called terminal, to enable the calling terminal to establish an end-to-end media channel between the calling terminal and the called terminal according to the session response message.

Abstract: This application provides a method for controlling a terminal to use a wireless network, a system, and a related device. The method includes: obtaining, by a network decision device, service information of a terminal, constructing network use indication information, and delivering the network use indication information to a network trigger device; and triggering, by the network trigger device based on the network use indication information, the terminal to use a wireless network corresponding to the service information. According to the method, an operator can assign, based on a service requirement of the operator, the terminal to use a specific wireless network, so that the terminal can use in time a wireless network that is consistent with a requirement of the operator. This helps improve network use efficiency for the operator, and can prevent a service of the terminal from being affected.
