Abstract

The invention discloses a method and a system for intercommunication between a first system and a second system, and a media gateway, and belongs to the field of the mobile Internet. According to the invention, client agents of a heterogeneous network are arranged in the media gateway; through a relay function of the media gateway, clients of the heterogeneous network and the client agents are enabled to obtain candidate address information of the opposite side and to perform connection detection, so as to establish connection; by the relay function of the media gateway, the media gateway is enabled to negotiate self media coding and decoding information with the clients of the heterogeneous network; then according to established connection in a segment manner and the negotiated media coding and decoding information, the relay transmission of media streams is performed; and finally, intercommunication between media streams of the clients of the heterogeneous network is achieved. As a result, the media intercommunication of the heterogeneous network is achieved, such as media communication between WebRTC (Web-based Real-Time Communications) and an IMS (IP Multimedia Subsystem).

Description

technical field [0001] The invention relates to the field of mobile Internet, in particular to a method and system for media intercommunication between a first system and a second system and a media gateway. Background technique [0002] WebRTC (Web based Real-Time Communications, web real-time communication), also known as RTCWeb, is a web-based real-time communication technology. In order to ensure the security of multimedia sessions, WebRTC stipulates that the SRTP (Secure Real-time Transport Protocol, Secure Real-time Transport Protocol) protocol is used as the bearer protocol for audio and video data. SRTP is a protocol defined on the basis of RTP (Real-time Transport Protocol, Real-time Transport Protocol), which aims to provide encryption, message authentication, integrity assurance and Replay protection. [0003] In an IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) network, communication between terminals uses RTP as a bearer protocol for audio and video da...
