4G宽带无线网络接入服务之关键性技术研究

摘要

Beginning with the introduction of WiMAX, this paper studies the 4G broadband wireless access network (BWAN), the international standard of roaming or nomadic users with connection to Internet access service, and the latest 4G wireless communication technology. At last, it conducts that three communication protocols to cut down IP lookup mechanism and the crucial technical mechanisms to solve the fast switching in 4G WiMAX network..%　　由WiMAX技术切入,研究第四代宽带无线网络接入服务(4G broadband wireless access network, BWAN),认识行动用户(roaming or nomadic user)连接互联网(Internet Access Service)的国际标准技术,并了解最新的4G无线通信技术,最后提出4GWiMAX系统中,三个降低IP查询的通讯协议,解决快速传递的关键性技术。
