Design And Implementation Of Mobile Communication Demo System

Mobile Communication Demo System is a kind of demo system which makes use of computer software and hardware technology to simulate phone calls principles and can be experienced by phone models display devices. The purpose of the system is to invoke users'interest in future communication technology through making users understand the principle of mobile communication by themselves. Meanwhile, the system also aims to reveal the future of mobile communication by large high-speed data communications.This characteristic of the Demo System mentioned in the thesis is that it is a comprehensive interdisciplinary subject, covering communications technology, software technology, hardware control technology and PV technology. The system consists of four main parts: MMI part, real-time communication, virtual communication network and virtual communications network control.Based on principle of mobile telephone communication and combined with the system needs, the paper analyses the overall structure and workflow of the virtual system while highlighting the CIP(Cellular IP).Subsequently, the thesis proposed design principles of virtual system, analyzed the system architecture, and designed from both the server-side and client-side on the ground of C/S (Client/Server) distributed framework; at the same time it probed into some relative technologies like communication protocols, users access control. And then, the thesis carried out a technical analysis about the communication method between computer software with CPLD(Complex Programmable Logic Device)through which it actualized the prototype. Furthermore, it detailed the system running mechanism and concluded the features of prototype. Finally, the thesis made a summary and discussed the future prospect of the system.This thesis presents a way through computer software and hardware simulation mobile communications principles. It can be applied to the field of science that have similar problems.The system has higher application value, and promotes the development of science education.
