Design And Implementation Of Mobile Wifi Client System Based On Android Platform

One of the main responsibilities of China Mobile is to cover WLAN (Wireless Local Area Network) throughout the country. WLAN is a wireless service provided by China Mobile, aiming to serve business persons, college students and company/government employees. Customers could get access to the internet through terminals (e.g. lap top, cell phone) for information, entertainment or work. This service aims to meet the growing needs of people to get access to the internet whenever and wherever possible.With the booming of both hardware and software in mobile phones and tablets, more and more features are involved in these electronic devices, through which a growing number of people are in demand of having internet connection. Therefore, the principle purpose of the current thesis was to carry out an Application based on Android operating system in order to support China Mobile to make possible WLAN connection. This software changed the log-in process from traditional website to client terminal on mobile phones. Additionally, clients are able to check the surrounding hot-spots to order WLAN plans, which simplified the complicated operation process.This paper firstly introduces the background of the topic, present situation, main contents and tasks of author. Then from the point of the users’experience, the paper analysis requirements of application, the detail of the functional requirements and the user interface. In addition, for the convenience of readers, this paper also provides the use case diagram of this Application and tells all the technical field relates for the client. Then, from the design of architecture and design of UI, readers could have an overall concept. Then, tells the division of function modules, and describe the function and preliminary design of each module. What’s more, the paper tells details of the design and implementation of the three module which the author participated in and responsible for, and gives the design and realization of renderings for readers’ reference.Finally, from the quality control point view of the Application, this paper introduces some basic principles and test indexes of the test, gives some of the test cases, and the standard when Application released. And then put forward some questions encountered during the development process, discusses and prospects for the future development of the Application.
