Design And Implementation Of Virtual Simulation Teaching Experimental System Of LTE

With the rapid development of the Internet and the continuous innovation of computer technology,many traditional industries actively explore the possibility of combining the industry and Internet technology,try to introduce information science and technology into traditional industries,which speeds up the development of the industry and optimizes the industry structure.In recent years,the online teaching system,developing rapidly and more mature,is the latest trendy of online learning.However,with the continuous expansion of social needs,the problem becomes increasingly obvious.The users only have one single form to learn through watching the teaching video and lack the personal experience in the experimental course of the real effect.How to optimize the experimental teaching,provide users with a variety of forms of learning is a pressing issues needed to solve.Based on the introduction of the research background and related technology of LTE online virtual simulation experiment teaching system,this paper mainly studies the following three aspects:(1)The system architecture of LTE online virtual simulation experiment teaching system is Designed,including the business server,network management server,terminal equipment and client application this four components.The experimental project is deployed on the system platform through the virtual experiment equipment,which is managed and distributed experimental resources by the system platform,and uses C/S software system architecture to achieve the client and the system platform information exchange.Student client application can access the experimental teaching platform through the Internet to interact with the actual LTE system to do the experiment,and the results can be real-time feedback to the students.This enables multiple students to share a set of LTE implementation systems without time constraints.(2)The LTE online virtual simulation teaching experimental system platform is set up.Firstly,the business server,background management platform and client functions are designed.Second,verified and a number of virtual experiment projects such as signaling analysis experiment,network planning experiment and business analysis experiment are integrated.(3)The communication protocol of each component based on TCP protocol is designed,which uses MySQL as the database in the business server,designes the mapping relationships between table and entity object,uses JDBC and Hibernate technology to write the database access interface and the data persistence module.In addition,the XML data analysis and encapsulation,encryption and decryption functions are designed and implemented.At last,The results show that the system realizes the unified management and resource allocation function of the experimental resources,and can effectively achieve the online simulation of LTE experiment,which can break the shackles of the traditional experimental environment and improve the quality of experimental teaching through testing the real experimental equipment,and the paper summarizes the thesis and prospects the research direction and ideas of the next step.
