摘要
针对VHF话音通信无法支持远距离通信的问题,对VOIP技术进行了研究。提出了一种基于会话初始协议(SIP)的VHF话音通信远程接入系统的实现方法,给出了系统体系架构,以及接入控制设备和远程控制软件的参考设计。系统中接入控制设备和远程控制软件实现SIP用户代理功能,从而提供接入SIP系统的能力。仿真结果证明了该方法的有效性,从而为VHF话音通信系统的应用范围扩展提供了新的思路。
In allusion to the problem that VHF（Very High Frequency） radio system can＇t be used for long- distance wireless communication, the technology of VOIP（Voice Over IP） is studied, and an implementation method of VHF voice communication access system based on SIP（Session Initiation Protocol） is proposed. The system architecture, reference design of the access control equipment and the remote control software are provided. The access control equipment and the remote control software in this system achieve SIP user agent function, and thereby providing the ability to access SIP system. Simulation results illustrate that this method performs better and thus providing a new thought to expand the scope of VHF voice communication system application.
