摘　　要：阐述一种既支持电路交换域又支持分组交换域的车载通信技术的研究方法,着重分析这两种通信模式的基本原理和通信过程,在此基础上介绍相应的车载无线传输单元的基本设计方法,最后重点说明其中关键的协议栈和算法。按照该方法研制的车载无线传输单元具备并行支持电路交换域通信和分组交换域通信的能力,可广泛应用在各种型号的车载系统中。This paper describes a research method of onboard communication technology that supports both Circuit Switching Domain(CS) and Packet Switching Domain(PS). It emphatically analyzes the basic principles and communication processes of these two communication modes, introduces the basic design method of corresponding vehicle borne wireless transmission unit, and highlights the key protocol stack and algorithm. The onboard wireless transmission unit developed according to the method introduced in this paper has the ability to support circuit switched domain communication and packet switched domain communication in parallel, and can be widely used in various types of onboard systems.
