Design And Implementation Of Mobile Transaction System Based On LBS Cloud Platform

In recent years, a large number of mobile applications spurt suddenly while the mobileInternet growing. With the rapid development of mobile terminal technology, mobile deviceswith GPS receivers spread quickly. Therefore, location based service (LBS) is becoming animportant trend of mobile Internet.In this paper, a mobile transaction system based on LBS cloud is designed. Firstly, somerelated technologies of LBS cloud, the framework of Android and ShareSDK socialcomponents are introduced in chapter2. Some key technologies, including localizationtechnology, cloud storage and retrieval, data encryption, the third party logging and sharing,are focused on. The design of system framework is achieved in chapter3according to therequirement analysis and the development mode of LBS application. The main framework isdivided into several modules. Each module and the associated database tables are designedcarefully. After that, chapter4realizes all the designed modules in code-level. The LBS cloudfunctions include localization, cloud storage and retrieval, while the mobile clients canprovide not only login and registration services but also releasing and retrieving informationabout products, sharing products and products locations. What’s more, the personalinformation, positions datum and product information are all encrypted. Finally, adequate testcases are designed to test all the modules. The results of the test and the optimization analysisare presented to ensure the stability and security of the system.The mobile transaction system is developed based on Baidu’s LBS open platform. Byusing the new model of LBS application, the location data and business data are managed byBaidu. Baidu provides API for cloud storage and retrieval. Thus, there is no need for thedevelopers to design the algorithm of spatial calculation, and they can only concentrate on thebusiness logic of the mobile client. This reduces the cost of development and maintenance andimproves the development efficiency.The mobile transaction system based on LBS cloud which is designed in this paper is acombination of LBS and mobile electronic commerce. It provides users a platform that userscan release transaction information, search and share nearby products information at any time.The mobile transaction system is a transaction software based on LBS which can be installedon smart phones. It is in line with the trend of mobile Internet.
