Research And Implementation Of Data Presentation Technology For LTE-A Air Interface Analyzer

With the flattening of the LTE-A network structure,the disappear of traditional signaling collection points,traditional test instruments are no longer applicable to LTE-A communication network,and fault location,post-maintenance,and optimization of LTE-A network are urgently to be resolved.As the only interface between the LTE-A access network and user terminals,Uu air interface is an important breakthrough point in monitoring of communications networks.The research and development of the LTE-A air interface analyzer is of great significance to communication network optimization and maintenance.This thesis is originated from the national science and technology project " New Generation Broadband Wireless Mobile Communication Network ",based on research and implementation of LTE-A air interface analyzer,the research and implementation of the data presentation technology has been completed,and the corresponding functions have been tested and verified.The main work of the thesis includes the following three parts:1.The LTE-A network structure,the air interface protocol stack and the related data presentation scheme technology are studied,the whole structure and functional requirements of LTE-A air interface analyzer are analyzed.The design of the instrument data presentation scheme is proposed,and the design of overall architecture,database and data interaction interface scheme are completed.2.Based on the overall architecture design of the data presentation solution scheme,data presentation function modules of LTE-A air interface analyzer are designed and implemented through MVC framework model JavaFX,Mybatis,Web Service and other technologies.Presentation capabilities including user management and device management,signaling decode,CDR,signaling flow diagram,protocol stack,constellation diagram and RB resource diagram.3.Using SoapUI testing tools,the design and implementation of functional modules in the scheme were tested and verified,the test results verify the feasibility of the data presentation program,shows that the program can meet the data presentation requirements of LTE-A air interface analyzer.Finally,the research results obtained in the thesis are summarized,the imperfections of the design scheme are analyzed,and research prospects of the project are prospected.
