Design And Implementation Of Android Client Data Acquisition Module In The Mobile Wireless Network Testing And Evaluation System

With the advent of the era of mobile Internet,the demand for network quality is raised.Network quality has become the key to the core competitiveness of the Mobile Networks operators.Network testing and optimization is the main method to improve the quality of the network.However,human and material resources cost is relatively high in the traditional way of road test and the sampling points are concentrated on the main road,and the consideration for the user experience is less from the network point of view.Network test applications based on smart terminal has emerged as the time require,but most of them encapsulate the test content so users can not determine whether the connection is safe and does not support batch task testing.For the above problems,this paper presents a scheme of wireless network testing data acquisition based on Android smart terminal.The advantage of this scheme is that the Model-View-Controller Mode of data acquisition module can solve the problem of batch test queue,which is realized by using callback mechanism.At the same time,it can improve the development efficiency,as well as facilitate the development and maintenance of other test items.Data acquisition module is the most important functional module of the Android Application.Through the research and analysis of the network optimization process and the existing Android network test Applications,the design and implementation scheme of data acquisition module based on Java callback mechanism and MVC hierarchical model is proposed.The main work is as follows:(1)This paper summarizes the current situation of mobile Internet and network optimization,and proposes an optimization scheme of wireless network testing based on Android smart terminal after the research of the existing Android network test Applications in the market.(2)According to the requirements,the data acquisition module of the program is divided into three sub-modules:authentication information acquisition sub-module,test data acquisition sub-module and data storage and display sub-module,and then gives the detailed design and implementation method of each sub-module.(3)We finished the software development of authentication information acquisition sub-module,data storage and display sub-module,data acquisition sub-module's MVC hierarchical model and Ping delay test instance.Testing and results analysis is carried out for the three sub modules,which shows that the proposed scheme is more convenient and easier to use than other network test applications when performing a batch test task and the results are more reliable.
