媒体网关控制器中H.248与SIP信令互通的研究

Research in H.248 and SIP Protocol Interworking in Media Gateway Controller

H.248和SIP是NGN网络中的两种重要协议,而媒体网关控制器(MGC)则是实现它们互通的重要设备之一。文章在分析了它们互通的必要性的基础上,分别对H.248和SIP协议进行了简单的概述,然后提出MGC的内部结构模型及协议互通的解决方案,最后,通过具体实例来研究它们互通的实现方法。

H.248 and SIP are two important protocols in NGN network,and Media Gateway Controller（MGC） is one ofimportant equipment to implement the interworking each other.On the basis of analyzing the necessity of the interworking,this paper makes a simple overview to H.248 and SIP protocol,and then presents the internal structure model of MGC and the solution of the interworking of protocols,and finally researches the implementation method of the interworking by practical examples.
