| Mobile communication becomes an integral part of people’s daily life. Mobile phone becomes to the thing which people go out with one of the items. With the development of science and technology, mobile phones have been given too many functions, mobile payments is one of them. As the name implies, mobile payments refers to mobile phones and other mobile devices achieve the transfer of funds, achieve the near-field payment in movement. Important medium in the mobile payment is the electronic wallet, using it must recharge. Currently, most ways of adding fund for mobile electronic wallet are fixed to recharge outlets or on a dedicated credit for lord equipment, these are very convenient for the user. Thus the concept of proposed air credit for lord system has been brought out; the use of air credit for load technology can achieve remote user account funds to mobile electronic wallet, completing the mobile payment functionality.This thesis discusses the concept of the mobile payments aerial transactions and "Load Credit Over The Air". After analyzing the domestic and international Load Credit Over The Air system development status, combined with the international norms Load Credit Over The Air system case, based on detailed analysis for the needs of the system, finished design of overall system, get development and operation finally:For the actual business of Load Credit Over The Air, we conduct feasibility studies, safety analysis and project needs research to determine the scope of the system and the overall planning.Completed the design of communications system module, universal service module and system database for the Load Credit Over The Air, proposed Load Credit Over The Air system architecture. The system deployment and commissioning, surveyed and analysed end-user feedback conducted, summed up some experience in system applications and discussed the future direction of development. |
