Design And Implementation Of Software For Portable LTE Packet Transport Network Tester

The packet transport network,which is the typical technology that bears integrated packet service in 3G,LTE and follow-up systems,is widely used in base station access in the mobile communication network,such as LTE.Meanwhile,for the maintenance and service of PTN business,it is necessary to test,regulate and optimize the quality and performance of PTN network frequently,on the basis of meeting the functional requirements,users set a higher requirement for the portability of the tester and the humanized man-machine interface.The thesis relies on the "R&D project of Chongqing Mobile"--"Research and Development of PTN Tester".Aiming at some disadvantages of traditional PTN tester,including large volume and poor portability,this thesis designs the B/S software architecture by combining embedded platform with smartphone(or tablet PCs and other intelligent devices).This architecture consists of the server played by embedded system and the client played by mobile browser.This thesis can be divided into the following four aspects:1.Firstly,the background and significance of the research are summarized,then the concept,technical standard and test method of PTN network are introduced,and finally,combining with the system requirements,software architecture is designed.Software architecture consists of three modules: the client human-computer interaction,the database system,and server module.2.The client man-machine interaction module is designed for the interface layout based on jQuery Mobile.Meanwhile,the asynchronous is used to resolve a series of problems,including page jitter and page blank due to frequent page refresh.3.Considering the database frequent operation will affect the life of the Flash memory,this thesis designs two databases.The date updated frequently is stored in in-memory database,including battery power,network status,etc.In addition,other date is stored in FLASH database.4.Based on message-driven mechanism,six function modules are designed and implemented for server module,which include MAC address registration authentication mechanism,network information configuration,network fault test,test report processing,system setting,and online monitoring.The function charts and flow charts are used in the design process of each function module,and all modules are implemented separately to improve portability and maintainability.The test results show that the tester has many advantages,such as no screen,good portability,simple operation,and practical function.The test report can be exported in batches,transmitted at a long distance by smartphones.Meanwhile,the tester achieves the centralized management of data.Finally,the thesis summarizes the work done and the research results,and carries out a prospect on the research.
