Embodiment 1

[0049] (1) Working principle

[0050] Such as figure 1 As shown, the present invention dynamically specifies media data transmission routes according to different types of network ISPs where communication terminals are located, and redirects default routes between ISPs in media transmission routes to internal routes between media relay transponders, and internal routes The reasonable deployment of the media relay server is completely controllable, and the controllable factors replace the uncontrollable factors, effectively improving the service quality of IP communication. The method and system of the present invention are applicable to various communication protocols of VoIP, and this embodiment uses the SIP protocol for illustration.

[0051] (2) Structure composition of IP communication system

[0052] Such as figure 2 As shown, the entire IP communication system can be divided into various terminal access devices and IP communication server systems. In the IP communic...

Embodiment 2

[0082] In this embodiment, a media relay transponder is selected for the IP communication system to perform communication. The difference with Embodiment 1 is that the content of steps (34), (35) and (36) in the mesh relay method for controlling the media transmission path corresponding to Embodiment 1 is different, using steps (34a), (35a) and (36a) marks, the specific description is as follows:

[0083] (34a) During the interactive process of establishing the control channel of IP communication, the Figure 8 Take the session establishment process of the communication terminals UA-1 and UA-2 in the example as an example. The ISP types of the communication terminals UA-1 and UA-2 are the same, and may be set as ISP-1.

[0084] A21. The communication terminal UA-1 wants to call another communication terminal UA-2. The communication terminal UA-1 first sends a communication request (that is, the INVITE message in the SIP protocol) to the signaling control server. The calling ...

Abstract

The invention relates to a mesh relay method and an IP communication system for controlling a media transmission path. The method includes setting one or more media relay transponders with public network IP addresses in the IP communication system; The device is divided into different groups according to the interoperability; in the registration process of the communication terminal, the IP communication system judges the ISP type to which it belongs; A combined pair consisting of two media relay transponders in the same group; the communication terminal establishes a media channel through the media relay transponder; after the communication ends, the IP communication system removes the media channel; the system includes a database, a network type detector, an information Command Control Server, Media Relay Transponder, and Media Relay Distributor. The invention effectively improves the service quality of IP communication, has strong implementability, good expandability, and has a good load balancing mechanism.

Description

technical field [0001] The invention relates to a processing technology in the field of network communication, in particular to a mesh relay method and an IP communication system for controlling the media transmission path by relaying the media streams of both communication terminals to improve the service quality of IP communication. Background technique [0002] The new Internet-based VoIP (Voice over Internet Protocol, Internet phone or broadband phone) technology is facing unprecedented opportunities for development. VoIP is a typical real-time service and has high requirements for QoS (Quality of Service). However, the IP network does not provide a perfect Qos mechanism, so that the service quality of multimedia services cannot be guaranteed. Unsatisfactory voice quality limits the wide application of VoIP technology to a large extent. [0003] Under the current Internet status quo, the interconnection between ISPs (Internet Service Providers, Internet service provider...
