摘要
为创建支持多设备、高性能、安全的网络,以提供低成本、综合性的通信服务,采用理论分析和实验的方法,构建一个典型的集有线、无线网络于一体的统一通信实验平台,给出语音接入网关的设计方案.语音网关以SIP协议为基础,分别以MPC850和嵌入式实时操作系统VxWorks为中央处理器和软件平台,以语音处理DSP、以太网控制器和SLIC为应用模块.研究结果表明:该通信平台设计方案是可行的;语音接入网关能有效控制用户,并完成模拟语音信号与IP分组包的转换.研究结论对小型综合通信平台的建设和相关嵌入式产品的开发有一定的参考价值和指导意义.
In order to create a multi-device supporting, high-performance, secure network to provide low-cost integrated communications services, theoretical analysis and experimental methods are adopted to build a set of typical communication experimental platform. It merges wired and wireless networks. Furthermore, a voice access gateway is designed which is based on protocol SIP. In this gateway, MPC850 and embedded real-time operating system VxWorks is used as the central processor and software platform respectively. In addition, voice processing DSP, Ethernet controller and SLIC together are used as application modules. The results show that the design of this communication platform is feasible and the voice access gateway can control the subscribers effectively and convert analog voice signals to IP packets. The research conclusions have certain reference value and guiding significance for the construction of small integrated communication platform and development of related embedded products.
