【摘要】 随着通讯技术的发展,手机有了更为广阔的发展空间。人们希望能够通过熟悉的因特网来为手机提供更多扩展。因此,为了满足这样一个需求,手机增值服务作为一个新兴行业发展起来,它通过一个电子商务平台,为我们提供更多的服务。在以往的手机增值服务中,通常是通过OTA(Over-the-Air Technology),即空中下载技术实现。这种方式往往受限于手机网络本身的局限性,网速慢、稳定性差等,限制了手机增值服务的发展。本文通过对手机增值服务的特点进行深入的分析,提出了一种C/S(客户端/服务器)结构的电子商务平台技术,简称为Offline系统。该系统即兼容了原来的B/S(浏览器/服务器)结构的OTA下载方式,又通过安装在客户机上的Client(客户端),可以使用数据线方式下载。该下载方式利用了互联网的高速性和稳定性,避免了原来手机网络的局限性。在本文提出的Offline系统中,针对实际的需求对现有的J2EE进行改进,提出了基于JSP/ Servlet[1]技术的平台架构。通过JAVA技术,将文件加密后传输到客户端供手机下载,同时也可以由OTA下载。通过实际的测试运行,本文提出的Offline系统可以稳定运行,并满足预定的目标,且可以比原有的OTA方式下载具有更好的性能。更多还原

【Abstract】 With the development of communication technology, cell phones have even broader space for development. It is hoped that more outspread can be offered to mobile telephone by familiar Internet. Therefore, mobile telephone value-added services has been developing as a new vocation to satisfy this need, which provide us more services via E-commerce systems.In the past mobile value-added services, usually through the OTA (Over-the-Air Technology).This means is frequently limited by the restriction of the mobile telephone network such as slow speed, poor stability and so on, which limits the development of mobile telephone value-added services. This paper proposes a e-commerce system technology with C/S(Client/Server) structure by analyzing the features of mobile telephone value-added services carefully, referred to as Offline system. The e-commerce system technology with C/S structure this paper proposed can not only download the information by the means of the former B/S(Browser/Server) structure, but also install the Client in the client computer and download the information by data line. This means of downloading information take advantages of Internet including high speed and perfect stabilization to avoid the restriction of the former mobile telephone network. The offline system proposed in this paper improve existing J2EE according to actual needs and propose plat architecture based on JSP/Servlet technology, which encrypts files and transmits to the Client for mobile telephone by JAVA technology, meanwhile allows downloading information by OTA.Through actual operation of the test, this paper presents the Offline system can be stable operation, and to meet the preset goal, and than the original OTA download a better performance.更多还原
