【摘要】 目前，基于LBS的增值服务是运营商追逐的热点之一，本项目以中国移动无线城市商家联盟为背景，LBS业务结合Widget技术，设计开发出了一款时尚实用的手机应用，给用户提供快速精确的定位以及周边商家优惠的查询。系统在透彻分析Mobile Widget技术的基础上，结合LBS应用的特性，把快速精确定位放在首位，运用了Cell-ID+GPS的混合定位技术，提出一个关于MapABC基站定位的消除偏移算法，使Cell-ID定位精确度提高。按照软件工程的方法，首先对系统进行了需求分析，并使用UML建模技术，给出了系统的架构图、流程图、用例图等等。然后将系统分为地图模块、定位模块、周边商家优惠信息获取模块、搜索模块、驾车导航模块、用户登录模块、收藏模块等七个主要模块进行了系统的详细设计，包括界面设计和数据存储设计。在系统实现过程中，用WAC SDK作为开发工具，采用Javascript+HTML+CSS进行开发，使用MapABC地图接口实现地图展示，利用JQuery技术添加功能，提高画面感和用户体验。最后对系统做了全面的测试，给出了测试报告和系统评价。本项目产出的基于Widget技术和定位技术的移动式商家优惠信息获取系统能够在安装了BAE引擎的任何手机平台上运行。系统的α版本已经在东莞移动公司内部上线运行了1个月，为进一步探索基于LBS的创新性widget应用打下基础。LBS和Widget相结合，无论在业务融合方面、业务体验方面、业务运营方面、价值链方面都对现有的增值业务客户端的应用形式作出有益的补充。更多还原

【Abstract】 Currently, the value-added service of LBS is one of the hot spots pursueby operators. It achieves some functions such as sign by cell phone, route queries and surrounding businesses preferential query. LBS applications are also deep into people’s lives, work, entertainment, traffic and other aspects. The common goal of the developers is that creating profits for the enterprise by making use of market trends combining with LBS services and widget technology. Thebackground of this project is wireless city business alliances. The project madean in-depth analysis of LBS services and Widget technology, design and develop a stylish and practical mobile phone applications that providing users with fast and accurate positioning as well as surrounding businesses preferential query.System used Cell-ID+GPS hybrid positioning technology based on Mobile Widget technology combining the features of the LBS application. It put the quickly and accurately positioning on the first place, proposed an eliminate offset algorithm about MapABC base station positioning to increase Cell-IDpositioning accuracy. In accordance with the method of software engineering,first of all, conducted a needs analysis of the system, and using the UML modeling techniques to draw architecture diagrams, flow charts, instance diagram.System was divided into seven parts. There were map module, positioning module, surrounding businesses preferential information obtaining module, searchmodule, car navigation module, user login module and Preference module. Then it carried out the detailed design of the system, including interface design a nd data storage design. In the process of system implementation, system used WAC SDK as a development tool and Javascript+HTML+CSS as core develop technique, and used MapABC’s map interface to display the map. It alsoused JQuery technology to add functionality and improve the screen qualityas well as user experience. Finally, the system did a full test, and output thetest reports and system evaluate reports.The output of this project is a portable businesses preferential informationobtaining system that based on Widget technology. It can run on any mobile phone which installed BAE engine. After great effort during the internship, the α-version of the system had run on the line within the China Mobile Communication Corporation Dongguan branch a month before. It lays the foundation forfurther exploration of innovative widget application based on LBS. Combinationof Widget and LBS have made a useful complement to the form of client application that about existing value-added services in terms of business integration, business experience, business operations, value chain and the driving force of the operators.更多还原
