METHOD AND DEVICE FOR ESTABLISHING CHANNEL

摘要

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.

1. A method for establishing a channel, comprising:
receiving, by a first web real-time communication (WEBRTC) signaling gateway device, a session request message transmitted by a calling terminal, wherein the session request message comprises an identifier of a called terminal, and wherein the calling terminal is a WEBRTC terminal; transmitting a query request message comprising the identifier of the called terminal to a WEBRTC server, and receiving an access mode in which the called terminal accesses a WEBRTC signaling gateway device and a gateway identifier of the WEBRTC signaling gateway device accessed by the called terminal, wherein the access mode and the gateway identifier are transmitted by the WEBRTC server, and wherein the access mode comprises accessing via a web browser; determining that the called terminal is a WEBRTC terminal according to the access mode, and transmitting the session request message to the called terminal via the WEBRTC signaling gateway device corresponding to the gateway identifier; and receiving a session response message transmitted by the called terminal, and transmitting the session response message to the calling 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.
