Design And Implementation Of A Real-Time Mobile Data Transformation System

The mobile data transformation plays a role as a bridge between traditional Internet and mobile Internet, through which the mobile terminal user can not only visit the special WAP websites, but also the WEB content that they can't visit in normal times.The mobile data transformation system in this paper is a new proposal that can transform WEB content to WAP content in real time. As the media between traditional Internet and mobile Internet, it can make the mobile terminals visit the massive WEB content in traditional Internet through their WAP browsers. Besides transforation, it has the following characteristics: support mobile terminal adaption; cache helps raise the speed to visit the same source next time; support Chinese; filter unhealthy information to fit the low transmission speed and small screens of the devices; transformation based on the structure and text accelerates the transformation speed; support both WML and XHTML transformation. Testing results demonstrates that system has better performance and display effect than other exsting systems. This paper introduces the related knowledge uesd in the design of the system, such as WAP protocol, WML, XHTML, DOM. Then the paper introduces the principle of transformation, the working principle and overall architecture of the system, design and implementation of some modules.
