The Research And Design Of LTE-D2D Based Mobile Payment Platform

An explosive growth appeared in third-party mobile payment in2013, and transactions are expected to exceed10trillion, mobile payment will become one of the major means of payment for the foreseeable future. And with LTE-D2D, we can provide strong authentication, at the same time, the D2D discovery information can directly as potential security authentication information, moreover EPC alert function can solve the common message delay. Therefore we need to research and develop a platform fusion of the LTE-D2D features, improve the safety and reliability of payment.Firstly, study the technical principle of LTE-D2D. Based on the research of the architecture model, discovery model, business procedure, I improved a secure authentication method to verify the authenticity of the transaction, and a synchronized message pushing method to ensure timely notification. The next is overall design, mainly includes the requirement analysis and network architecture. I design variety of business message, analyze the Asio asynchronous communication mechanism. And the database system is researched and designed in detail.After the design of the platform, a generic server framework has been abstracted, to implement business data and communications independence. The framework achieves a multi-machine distributed deployment, dynamic plugin management, for subsequent business implementation provides a simple interface. Finally, take some performance testing for the framework, the results shows the framework is enough to cope with the business requirements.
