Problems solved by technology

The disadvantage of this implementation scheme is that the signaling interaction between each MCU is complicated, and the service platform also needs to interact with multiple MCUs, so that the function division of the service platform is not clear enough, and its conference control operation becomes more complicated.
This greatly increases the complexity of the system and reduces the scalability of the system

Embodiment Construction

[0027] The specific implementation manner of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Such as figure 1 As shown, the main components and associated network elements of the MCU cascade implementation system in the embodiment of the present invention include: service platform AS, conference management function controller MRFC, resource management system RMS, network management system NMS, and multiple network management systems managed by the network management system NMS. The multipoint control unit MCU and the user terminal UE, in the figure, the solid line represents the signaling flow, and the dotted line represents the media flow. Among them, the conference management function controller MRFC is the core of the whole system. Its main function is to establish a conference model according to the conference management signaling of the service platform AS. The conference model includes the cascading and main ...

Abstract

The invention discloses a method and a system for realizing multi-point control unit cascading of an IP multimedia subsystem. In the method, a meeting ruling function controller (MRFC) establishes a meeting model according to a meeting ruling signaling of a service platform (AS); the meeting model comprises cascading and master-slave relationship among attended multi-point control units (MCU); and the MRFC controls a meeting operation of the attended MCU according to the meeting model. Because the meeting ruling function is independent and is concentrated on the MRFC, the invention ensures clear signaling interactions with simple and convenient operation, and system coupling degree and system complexity are reduced.

Description

technical field [0001] The present invention relates to the technical field of multimedia video conferencing, and specifically relates to a method and device for realizing multipoint control unit (Multipoint Control Unit, MCU for short) cascading of an IP Multimedia Subsystem (IMS for short). Background technique [0002] Video conferencing system, also known as video conferencing system, refers to two or more individuals or groups in different places, through transmission lines and multimedia equipment, to exchange sound, images and documents to achieve real-time and interactive communication. System equipment for meeting purposes. [0003] With the gradual development of video conferencing services towards the carrier level, the problem of conference capacity becomes more and more important. The general solution to this problem is to use multi-MCU cascading technology. [0004] The current video conferencing system is generally implemented based on the H.323 series protoc...
