Design And Stimulation Of Mobile Phone Network Quality System Based On Hadoop

From hardware to software,a variety of high-tech technologies are changing with each passing day,and the functions of mobile phones are becoming more and more abundant.Many years ago,people used mobile phones only to make calls and send messages.Now,there are quite a lot functions like listening to music,watching videos,chatting with others and shopping.However,while mobile phones bring convenience to people,they also bring a lot of troubles.For example,the problem of slow Internet speed caused by poor signal is often frustrating.There is an urgent need for a system that can automatically calculate which of the three operators near the user has a better signal.In this way,users can selectively choose the direction and location of good signal to surf the Internet.Therefore,considering this aspect,the design and implementation of this system is of practical significance.There is a variety of speed measurement softwares on mobile phone software market.They can test the user's current location of the network speed,but only stay in the collection of information,and they do not make advantage of this information for further use to help users and operators.Therefore,these existing softwares can make the system have reference and further innovation.Based on this design background,a telecommunication signal diagnostic system based on Spring MVC is designed and implemented in combination with the relevant theoretical methods of software engineering.The system has many functions like viewing nearby network quality graphs,network uplink and downlink rate graphs,connection number graphs and popular mobile phone model graphs.The paper collects and shows the advantages and disadvantages of relevant research at home and abroad and related functional products in today's software market,and summarizes the relevant needs,as an opportunity to carry out the corresponding design and development work.Based on this,it is hoped that the telecommunication signal diagnosis system studied in this paper can provide a convenient,stable,reliable and safe utility for the vast number of users,and provide operators with an accurate and timely actual communication equipment working conditions.The work content of this paper is shown below:(1)This part collects and shows the advantages and disadvantages of relevant research at home and abroad and related functional products in today's software market,and summarizes the relevant needs,and clarifies the main research content and purpose of the thesis.(2)This part studies the relevant techniques used in the system.Namely,the Spring MVC framework and the Spring framework,as well as my Sql database,Hive data warehouse,HBase database as a storage tool,as well as the use of new technologies,such as some features related to big data technology such as Hadoop,Spark,Kafka,Flume and so on.(3)This part analyzes the functional,performance and security requirements of the system,and draws use case diagrams from the perspective of administrators and users.(4)This part designs the system,gradually refining it from the whole to the parts,also designs the database fields and expounds the structure of each part.(5)In this part each module is specifically implemented according to the functional requirements,and heat maps and other diagrams are made.Test cases are also written for each functional module,and tested from the requirements and performance to determine whether it meets the pre-conceived.The result shows that the system has met the requirements.(6)This part summarizes the shortcomings of the system and looks forward to the future where the system can be improved.
