Abstract: The significance of the study on mapping rules of SDL model into C language is introduced. According to TETRA protocol, this paper analyzes some mapping rules of the two languages, which is presented in four aspects: data type, signal transferring, signal reservation and process schedule. It discusses the issue about enhancing the efficiency of mapping in the practical application. The rules can enhance the efficiency of the generated code. It is suitable for the particular operation system that the automatic mapping tool can not employ.
