摘要
随着移动通信技术的发展,诞生了各种可供接入的网络,如GPRS,WALN等。它们传输速率和原理各不相同,不同异质接入网络之间的切换已经成为对下一代无线网络的一个基本要求。本文介绍了一种新的切换机制,首先分别介绍了SIP技术与移动IPv6技术的原理,然后结合SIP与移动IPv6技术提出一种全新的无缝切换机制,最后总结并提出了有待进一步研究的相关问题。
With the development of mobile communications, many kinds of networks have occurred, and due to their different transfer speeds and theories, a seamless handover across heterogeneous access networks has become a fundamental requirement of the next generation wireless network. This paper described an innovative handover mechanism. SIP and Mobile PV6 technologies are presented at first, then the seamless handover mechanism based on SIP and Mobile IPV6 is proposed, and finally the key issues on seamless handover are summarized, some research challenges for future work are given.
