Research On Mobile Devices Wireless Access To The Internet Based On Bluetooth Technology

As the 3G era, mobile devices have become an indispensable tool in life to become a mobile information age, management of personal affairs, work and life of tools, the user easy to operate, and its prevalence is steadily increasing. All kinds of notebooks, mobile phones also are equipped with Bluetooth devices.Bluetooth technology is familiar to more people. People want a variety of mobile devices like computers to easily access the network anytime, anywhere to find information, view news, etc.,without the high cost of communication costs. The face of the above requirements based on Bluetooth mobile terminal access network gradually become topics of great concern to people.J2ME (Java 2 Platform Micro Edition) is a new development technology in recent years with the development of embedded devices, especially the rapid development of mobile communications equipment and the birth of a new development technology.J2ME located in the consumer electronics and embedded applications,the use of its equipment for a variety of portable intelligent features to improve the efficiency of application development, and mobile devices, intelligent, diverse, providing a revolutionary solution.By analyzing the Bluetooth protocol of communication theory, according to Bluetooth mobile terminal access network design goals of specific projects, given the overall design of the system, the system of functional processes, and insight into the realization of the key technologies required for the system. In particular, for mobile terminal access network process, we propose a new implementation method: Using Java MIDP mobile terminal platforms in the development of Bluetooth communication software, server used J2SE implementation in Windows platform. The Bluetooth communications suite is not only great research significance, but also has some practical value.Paper describes in detail how to use the mobile terminal equipment JABWT design software, serial port emulation protocol (RFCOMM) conducted a detailed analysis and in-depth research, to achieve the Bluetooth protocol and the existing network protocol PPP, TCP / IP protocol and data between conversions. We adopt the protocol of RFCOMM / PPP / TCP/UDP / IP in Bluetooth applications to realize LAN access over mobile Bluetooth devices via Bluetooth wireless access network. Bluetooth pairing PIN code in the defense attacks the defense presented a new method to improve the safety performance of Bluetooth networks.
