基于MGCP的媒体网关控制器的分析与仿真

Simulation of media gateway controller based on MGCP

MGCP(Media Gateway Controll Protocol)作为一种著名的媒体网关控制协议,许多厂商都在它的基础上开发媒体网关(MG)及媒体网关控制器(MGC)。MG的开发离不开MGC的配合与支持,然而开发MGC的低效率、长周期往往成为MG开发的瓶颈。着眼于此,在介绍了基于MGCP的VoIP系统结构的基础上,引入一种VoIP仿真工具Artiza VoIP Simulator,接着详细描述了怎样通过此工具仿真MGC实现跨MG通话。

As one of the famous media gateway control protocols the MGCP is widely used in the design and development of the media gateway ＆ media gateway controller. The MGC is absolutely necessary for the development of the MG. However the inefficient development of the MGC is usually the checking point of the MG development. An efficient VoIP simulator Artiza VoIP Simulator is introduced. After the overview of the framework the MGCP-based VoIP system the simulation of the MGCP and MGC is described in detail to implement the communication between two MGS.
