However, the need of test system is still intense due to the complexity of the protocol in WiMAX devices is too high to be checked manually. In the work of our team, we provide an inexpensive, easy-to-use test system for WiMAX developers to perform protocol conformance tests (PCT) on their products. The work of this thesis presents the implementation of the codec module and code generation functions for type & variable in our test system. With the codec module we provided, messages in any PCT test cases can be translate to corresponding WiMAX packets.Contents iiiist of Figures vist of Table viibbreviations viiicknowledgements ix Introduction 1.1 Background 1.2 Thesis Framework 5 TTCN-3 6.1 TTCN-3 Test System 7.2 Basic language elements of TTCN-3 10.2.1 Data Types 12.2.1.1 Subtype 13.2.1.2 Simple basic types & basic string types 15.2.1.3 User-defined types 17.2.2 Test Data 18 Architecture of TTCN-3 Module in WiMAX Test System 22 TTCN-3 Module Implementation 25.1 Code Generation of TTCN-3 Type & Variable 25.1.1 New Created Data Types 26.1.1.1 integer type in TTCN-3 26.1.1.2 bitstring & octetstring in TTCN-3 27.1.2 Code Generation of Type Define 28.1.3 Code Generation of Variable Instance 32.1.4 Result of Type & Variable Part 33.2 Codec 34.2.1 Decoder Function of Codec 37.2.2 Encoder Function of Codec 39.2.3 Message Structure Definition of Codec 41.3 Socket Connection Program 41 Experiment 43 Related Works 47 Conclusions and Future Works 49ibliography 52ppendix A TTCN-3 Files in PCT Test Cases 53ppendix B Pseudo Codes of the Codec 552306806 bytesapplication/pdfen-US編碼/解碼測試自動化轉接器通訊協定TTCN-3測試語言WiMAXTTCN-3CodecTest automationAdaptorthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/189121/1/ntu-97-R95943168-1.pdf
