The Design And Implementation Of Mobile Payment System For Changchun Light Rail

With the development of communication networks, the electronic information technology of electronic information has had a greate impact on daily life of people . Now , shopping online and consuming with credit card is the mainstream. In recent years , upgrading of mobile phone , appearing of 3G , and reducing of phone's price , all of these make users of phone and the demand of services of mobile payment to increase . Banks and mobile operators are all working to develop the services of mobile payment. services of mobile payment has the feature of convenience and shortcut , the more and more users use the services of mobile payment , at the same time the services of mobile payment brings more benefit . The report of the Sixth Global Forum on Payment expected that the scale of services of Chain's mobile payment may reach hundred's of billions .This paper based on Mobile Payment System for ChangChun Light Rail , I research many systems of mobile payment ,like the system of mobile payment based on WAP , the system of mobile payment based on SMS , the system of mobile payment based on GPRS ,and so on . I summarizes the classification for the system of mobile payment and the often used technology for the system of mobile payment. Through those ,I design the system of mobile payment for ChangChun Light Rail with those technology .I study mainly the following aspects :(1) According to the the actual situation for Changchun Light Rail Group and Jilin Mobile's Group, this paper designe three application to meet the practical need , and then compare them by the advantages and disadvantages .Because the 3th application registers easily, recharges easuly , not changes the habits of users and it also is simple to perfect the system of transformation , so this paper chose the 3th application as the solution of this system.(2) By the selection of the system solution and the researching of mobile payment system , I designed the system's hierarchy and network topology on Mobile Payment System for ChangChun Light Rail . Based on the actual demand , I divided the large module to some more particular module .(3) Studying and researching the OSGI framework mainly ,this system based on the OSGI framework to construct .OSGI has the modular thinking that it can meet the need of scalability, reliability to the system of mobile payment . So in JAVA platform, I implemente the system by using the way of SOA to develop and using OSGI in the core of system architecture.
