WiMAX-Based VOIP Business Implementation And Research

In recent years, Internet has made rapid development and wider application, as its core technology IP protocol in framework of the rule of position has been widely accepted. Meanwhile, with the IP-based technology to a variety of application, especially VOIP technology proposed, the data communications network gradually integrated into the traditional voice business. VOIP Voice Gateway as a system of key equipment for the voice network and data network integration, smooth transition to the future triple play in the VOIP system plays an important role.Another important emerging technological innovation in the field of wireless communications, WiMAX technology by virtue of their initial investment, business and service providers bearing made of the unique advantages of the recent communications market has become a hot spot. Clearly, based on the WiMAX wireless and wired Internet access in VOIP Voice Gateway has strong practical significance and value.The main content is based H.323 protocol support cable access the Internet VOIP voice gateway, detailed voice support for the four-way Voice Gateway Design and Implementation; through studying and researching WiMAX technology, select WiMAX communication module to support wireless access terminals programme.In this paper, the innovation lies in the realization and understanding of the development platform has been proposed on the basis of support WiMAX wireless access solutions, and on the gateway software and hardware design and implementation, and the key technology of VOIP were studied.The full text is divided into five chapters, Chapter 1 on the application of VOIP, WiMAX technology and communications platform for the development of VOIP business trends, topics of significance and application prospects. Chapter 2 introduces the main key to VOIP technology. Chapter 3 research WiMAX technology, as well as access protocol standard. Chapter 4 of the first selected through analysis and comparison WiMAX module, made hardware solutions. Chapter 5 details of the Tornado software development platform, software design method and its key technologies. And that the software encountered in the process of testing some of the practical problems and solutions. Finally, through summing up the preliminary results of the work, project development for the future.
