The recent advance in wireless communication and computer technology has provided the users with the access to data and services in any physical location and even in moving status. The situation and special limitation of this kind of database such as the variable bandwidth, restricted resources in mobile host and so on are the reasons for the traditional transaction processing methods not to have the necessary application in mobile database system. By this target, we have presented a method in this research in order to somewhat overcome some of the mentioned limitation. Firstly, the recommended way tries to predict the user's moving path by using the cellular learning automate and next through the file comparison way, it uses the propagation method to send the users' necessary data. The transferred unit in the recommended method is a type of improved compact that in case of request, not all compact is needed to be transferred. In order to have a research regarding this issue, it is essential for the compact object to be capable of dividing into logical parts.
