Design And Optimization Of Push Service System On Android Platform

As the development and improvement of mobile network, more and more people tend to access information and service via mobile devices, Android platform emerges because of the demand of smart phones. Push technology is a kind of technology that pushes information from server to client, which has been widely used in Internet, what’s more, mobile platforms have started to absorb push technologies but faced problems such as power overhead and safety problems, so it is important to promote a push service system that solves these problems.To be compared with the traditional push service systems, the one promoted in this paper adopted Apache Mina framework in design, which can help to managed Socket connection from client to server efficiently and clearly. Based on the framework, this paper designs and proposes a new framework with customized protocols and features of loose coupling and inversion of control.In addition, as to improve the push service to adapt to the demands of users, this paper talked about the context awareness analysis methods of mobile platforms, and proposed an optimization of push service based on user context analysis. This optimization’s core concept is to predict future push message arrivals and user demand of push service by learning the history of user context, and then dynamically decide which push mechanism to choose, which saves power and other resources however has little impact on the real-time feature of push service.Then, this paper used a push system of commodity information as an example, talked about the key points of technology and the solution to the problems. Then we tested and analyzed the system to prove the practicability and significance.At last, the paper gave a summarization and outlook of the push system.
