The Desigh And Implementation Of VoLTE Testcase Based On TD-LTE Terminal Protocol Analyzer

In the mobile communications industry,protocol conformance test is a test that must be passed before the terminal equipment brought to the market.The thesis topic is derived from a country's major research project "TD-LTE-A terminal protocol analyzer based on TTCN".The theory of protocol conformance test and the specification of VoLTE and VoLTE test of 3 GPP protocol is studied and some test cases from 3 GPP TS 34.229-1 is implemented in the thesis.The thesis is divided into five chapters:In the first chapter of the thesis,the background of the project and the author's work and result are been descried.The second chapter is for the reader's ease of understanding of the thesis.In the first part of this chapter,the hardware architecture and software Architecture of TD-LTE protocol analyzer is been present.In the second part,the software architecture of VoLTE and VoLTE Tester and SIP technology is introduced.In the last part,a way to develop test case based TTCN-3 is present.The third chapter of this thesis,the author analyses the specification of protocol 3GPP TS34.229-1 and gives an TTCN-3 implement of 4 test cases,which is authentication,mobile terminated speech call,mobile original video call,mobile terminal video call.The forth chapter gives the manually verification and automated test results of the test cases.In the manually verification part,the article gives the result of every test point of test case and analyzes the reason why the test point passes.The last chapter is the conclusion of the thesis.This chapter is to sum up the result of the author's work.The fruition of the thesis has passed the GCF authentication and integrated into the tester and runs stably.
