Design And Implementation Of The Testing Platform Under TD-LTE Broadband Wireless Trunking

Traditional narrow-band communication couldn't satisfied with the increasing needs of new service and application as the communication technology developed in high speed.It's an inexorable trend for mobile communication to make a transformation from narrow-band to broadband.The TD-LTE broadband trunking communication system becomes the primary trend of communication research.In the development of TD-LTE broadband trunking communicaiton project,lots of tests should be taken to make sure the data updating and the sub-module development,especially the protocol stack's stability is assured.In case of this situation,a TD-LTE protocol stack testing platform based on Linux kernel which has a good user interface is needed to finish the testing of whole protocol stack development.This testing stack should operate easily,comprehensive functions and test stack in a offline state so that it can increase the rate of developing tests and decrease the cost of testing.This thesis is about the testing platform based on TD-LTE broadband trunking communication system protocol stack.The main job is the development of testing and analyzing module,the protocol conformance testing and and performance testing of TD-LTE broadband trunking communication system protocol stack.Chapter 1 introduces the background of this thesis,points out the main job of the author,and gives the thesis' s structure.Chapter 2 starts with the basic development demand of TD-LTE broadband trunking communication system,takes research on the testing method of TD-LTE broadband trunking communication system protocol stack,and gives specific analysis on standard protocol of stack.At the end of the chapter,technologies related is introduced.Chapter 3 gives analysis of testing platform of protocol stack,the whole structure and the interface based on chapter 2.By classifying the function of testing platform,it mainly introduces the module of conformance testing and makes realization of it.Chapter 4 verifies the function of testing platform in three directions.It's divided into testing platform,protocol stack and the interactive between testing platform and protocol stack.Chapter 4 tests the three part of testing platform for many times to make sure it's correct and perfect.The last chapter of this thesis summarizes the whole work and points out the work next.
