Protocol testing theory is derived from software testing theory. Protocol conformance testing is the foundation of other protocol testing, such as interoperability testing IOT and performance testing; it can test the protocol implementation according to its specification to improve the probability of successful intercommunication between two protocols. The ISO-IEC9646 standard described by ISO is the most mature theory in protocol conformance testing theories. In this paper it summarizes and analyzes the theory in the standard combined with the requirement of the GSM-R IOT. The TTCN-3 Tree and Tabular Combined Notation-3 based on ISO-IEC 9646 standard is adopted to describe test suite of GSM-R protocol, and it introduces Specification and Description Language SDL commonly used for the development of test system.
