Abstract


With the fast development of3G and the quick popularization ofAndroid-based or ios-based intelligence mobile terminal, enterpriseprefer to choose mobile information as the development direction ofenterprise information construction。Mobile informatization means to makethe information system applications from government and enterprise workon mobile terminal, such as cell phone, PDA by using communication networkand Internet,and finally, to realize the purpose of working with theseapplications anywhere and at any time, adapting is one of the main waysof transplanting the enterprise applications to mobile applications.This paper provides a services-oriented software system structure,different functional units of adapted application are defined as services,these services are linked together by some well-defined interfaces, theseinterface is defined neutrally and has nothing to do with hardwareplatform, operating system and programming language. By using thisstructure, services building in such system can interact with a unifiedand general way. In comparison with existing mobile adapting system, thesesystems obtain advantages in expansibility and efficiency.In order to improve the performance of the whole system, cache is addedto the adapting platform, by load some of the files form application serveror medium files from the adapting server to the memory, it can reduce theresponse time of the request when the system is busy, as a result, theend-users can get a better experience. Based on the characteristic of theplatform, this paper proposes a page preload scheme. It Construct adynamic association rule tree by the site structure of the applicationserver, then it can predict the future requests when terminal initiatingrequests, the predicted results will be loaded into the cache. This scheme can reduce the waiting time of the terminal at the expense of more networkflow.
