Abstract

This paper will discuss a new approach to standardize call control in Voice over the Internet applications. Voice over the Internet applications are the latest commodities in the technology world and people with related expertise are working to make the system more efficient with respect to both the quality of service and the economic point of view. The major problem currently facing solution providers for Voice over the Internet applications is the lack of interoperability. That is the Voice over the Internet Protocol (VoIP) system of one provider is not compliant with that of another. The reason the providers need to be in compliance is that if more gateways are able to communicate with each other more connectivity is achieved. Greater connectivity, in turn, reduces the cost for the users. It is with interoperability in mind that people started the development of the Media Gateway Control Protocol (MGCP) where the ultimate goal is to make all products compatible. The Media Gateway Control Protocol is a messaging protocol that specifies the way in which a call agent and the gateways communicate with one another. The basic implementation of the MGCP protocol is composed of two modules the call agent, which is also known as the Gatekeeper and the gateway.

Internet语音应用中呼叫控制的标准化:MGCP方法

本文将讨论一种新的方法来标准化互联网语音应用中的呼叫控制。互联网上的语音应用是科技界的最新产品，具有相关专业知识的人员正在努力使该系统在服务质量和经济效益两方面都更有效率。目前互联网语音应用的解决方案提供商面临的主要问题是缺乏互操作性。也就是说，一个供应商的VoIP (Voice over the Internet Protocol)系统与另一个供应商的不兼容。提供者需要遵守的原因是，如果更多的网关能够相互通信，则可以实现更多的连接。更强的连接性反过来又降低了用户的成本。正是考虑到互操作性，人们开始开发媒体网关控制协议(MGCP)，其最终目标是使所有产品兼容。媒体网关控制协议是一种消息传递协议，它指定了呼叫代理和网关相互通信的方式。MGCP协议的基本实现由呼叫代理(也称为Gatekeeper)和网关两个模块组成。
