【摘要】：3G时代数据传输速率越来越高,人们可以利用无线终端随时随地的下载小说、图片、铃声和动漫等移动数据资源。移动增值业务是当今电信业发展的热点,移动下载技术也是当今电信业的研究热点。本课题对移动数据下载系统进行了详细的设计与实现,客户端和服务器端相互通信是该系统实现的关键。现有的移动终端平台有iPhone、Android、BlackBerry、Windows Mobile和BREW等。本课题设计了一个客户端的通用框架,具体是在BREW平台和Android平台实现的。它不仅包括解压缩模块、列表模块、短信数字下载计费模块、跳转模块和保存模块等共性功能模块；还包括小说的阅读与分页模块、图片浏览与壁纸设置模块和铃声试听和设置等个性功能模块。服务器是基于VS2008平台开发的,是支持多种移动平台的通用服务器。它具有的功能模块有路径遍历模块、信息读取模块、分页传输模块和压缩模块等。另外,本课题应用多线程技术和异步非阻塞技术实现了服务器异步通信和支持多个客户端同时访问。本文的创新点是采用了短信数字下载计费,用户可以对自己感兴趣的图铃、动漫或小说等文件分别付费下载。另外一个创新点是通过路径的遍历实现文件的查询和页码的选择,避免因手机性能的差异而出现的输入法问题。
[Abstract]:With the increasing data transmission rate in 3G era, people can download novel, picture, ringtone, animation and other mobile data resources anytime and anywhere by wireless terminal. Mobile value-added service is a hot spot in the development of telecommunication industry. Mobile download technology is also a hot research topic in the telecommunication industry. This paper designs and implements the mobile data download system in detail. The communication between client and server is the key to the realization of the system. The existing mobile terminal platform includes the iPhone and Android BlackBerry. Windows Mobile and BREW. This paper designs a general framework of client. It not only includes decompression module, list module, short message digital download charging module, jump module and save module, etc. Also includes the novel reading and paging module, picture browsing and wallpaper setting module, ringtone audition and setting and other personality function modules. The server is based on the VS2008 platform, is a general server supporting a variety of mobile platforms, it has a functional module of path traversal module, information reading module. In addition, multi-thread technology and asynchronous non-blocking technology are used to realize asynchronous server communication and support multiple clients to access at the same time. The innovation of this paper is the use of SMS digital download billing, users can be interested in their own picture bell. Another innovation is to realize file query and page number selection through path traversal to avoid the problem of input method because of the difference of mobile phone performance.
