摘　　要：随着建筑企业信息化的发展,视频会的应用场景越来越多。需要采用新的视频会议系统,实现在更多终端、更多场景中召开视频会议。但同时会造成企业新旧视频会议系统的相互兼容和硬件对接问题。为解决这一问题,以市政公司视频会议系统建设为背景,从MCU主要结构和软交换处理机制入手,设计了将MCU中的H.323服务(MPGK)和分发服务(Slaver)提取后单独部署为网关的方案,给出了进行网关部署的过程和方法,同时对网关将两个不同视频会议系统的视频流转发的稳定性及兼容性进行了效果验证,实现了跨网段对接视频会议的目标。为同类问题的解决提供了借鉴和参考。With the development of construction enterprise informatization,there are more and more application scenarios of video conference.A new video conference system needs to be adopted to hold video conferences in more terminals and scenes.But at the same time,it will cause the problems of mutual compatibility and hardware docking between the old and new video conference systems.In order to solve this problem,taking the construction of video conference system of municipal company as the background,starting with the main structure of MCU and soft switch processing mechanism,a scheme of extracting H.323 service (mpgk) and distribution service (slave) in MCU and deploying them separately as gateway is designed,and the process and method of gateway deployment are given,At the same time,the stability and compatibility of the gateway forwarding the video streams of two different video conference systems are verified,and the goal of docking video conference across network segments is realized.It provides a reference for the solution of similar problems.
