Embodiment Construction

[0069] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0070] An embodiment of the present invention provides a method for channel establishment, such as figure 1 As shown, the method includes:

[0071] S101. The first WEBRTC signaling gateway device receives a session request message including a called terminal identifier sent by a calling terminal.

[0072] Wherein, the calling terminal is a WEBRTC terminal.

[0073]Optionally, before the first WEBRTC signaling gateway device receives the session request messa...

Abstract

Embodiments of the present invention provide a channel establishing method and apparatus, relate to the field of communications, and can reduce the number of data transmission paths when two Web Real-Time Communication (WEBRTC) terminals transmits data through IMS network, network delay and the load of media gateway devices. The method comprises: a WEBRTC signaling gateway device receives a session request message including the identifier of a called terminal and sent from a WEBRTC terminal as a calling terminal, determines that the called terminal is a WEBRTC terminal according to the access mode in which the called terminal accesses the WEBRTC signaling terminal, and sends the session request message to the called terminal through the WEBRTC signaling gateway device accessed by the called terminal, so that, after receiving a session response message initiated by the called terminal, the calling terminal establishes an end-to-end media channel with the called terminal according to the session response message. Embodiments of the present invention are used for channel establishment.

Description

technical field [0001] The present invention relates to the communication field, in particular to a channel establishment method and device. Background technique [0002] WEBRTC (Web Real-Time Communication, web real-time communication) is a technology that supports web browsers for real-time voice or video conversations. Among them, browsers capable of WEBRTC communication are called WEBRTC terminals. The browsers at both ends of real-time communication must support SRTP (Secure Real-time Transport Protocol, Secure Real-time Transport Protocol) to encrypt media resources, and support ICE (Interactive Connectivity Establishment, interactive connection establishment) function to traverse NAT (Network Address Translation, network address translation) devices and firewalls. [0003] IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) is a network architecture based on IP network to provide voice, that is, multimedia services. It uses SIP (Session Initiation Protocol, Sessio...
