Research And Implementation Of Mobile Communication Technology Based On Windows CE

From the development of mobile phone, the development direction of mobile phone technology will be the integration of computers, communication products, electronic products and the integration of the Internet, telecommunication networks and electricity networks. With the current trend of the development of mobile phones, this thesis discusses a method of the realization of mobile communications equipment, which is based on Arm9 on the microprocessor and Windows CE operating system. This equipment will be able to integrate handsets, personal computers and the Internet. Also, the thesis will give an introduction of the Windows CE operating system migration to the development board and mobile communications equipment system development in details.Main research and innovation in this thesis can be found in the following areas:1) At first, as an embedded software development, it will need the support of hardware. This thesis adopted ARMSYS2410-B researching board that produced by Hangzhou Liyutai Company. For the expansion of GPRS module of the system, interface technology was used to achieve Siemens MC55 and BenQ M22 two GPRS module separately. Platform Builder 4.2 was used to customize Windows CE operating system that needed.C# was used as the language of programming. The customized system and the compiled program were downloaded by ActiveSync to the development board's Nand Flash.2) Achieved the communication through GPRS mobile communications equipment and network computing on the Internet. With a downloaded PC end of the software, PC users can make an access to the telecommunication via the Internet and mobile communications. China Mobile is used to send messages newly through GSM-way and only a small amount of information can be sent out every time. This system discussed in the thesis can send large amount of bytes for the using of TCP protocol transmission.3) The development board selected in this thesis has three serial ports, but only in the development kits provide a serial port driver and which is also a serial debugging. For the messages are transferred between GPRS module and the development board controller via the serial port, three-serial-ports driver has been exploited in this thesis. 4) The content of messages and the content of the communication though Internet has been DES encrypted for the protection of personal privacy.The research has significant meaning from academic and realistic aspects. In this thesis introduce the exploring process, features and technology of the application which is based on the Windows CE. Through the study of the Windows CE and with my personal experience, a smart phone with basic functions of mobile communication equipment has been exploited. And the tow aspects in DES encryption of the content of the communication and the communications through computer on Internet have been deeply discussed.
