摘要
目前,随着WLAN的发展,VoIP(Voice over Internet Protocol)技术在其中的应用也越来越广泛。但VoWLAN仍然面临着移动终端切换时延过长、话音容量低、安全隐患以及QoS保证等技术上的挑战。文章简要介绍了VoIP技术,重点研究了VoWLAN终端的移动性管理,在现有支持移动性管理协议的基础上,融合各层协议提出了一种改进的移动性管理新方案。
Nowadays, with the development of wireless local area network (WLAN), the technology of voice over Internetprotocol (VoIP) and its application have become more and more popular. However, VoWLAN still faces these following challenges, such as long latency, low voice capacity, security and QoS support. This article introduces the technology of VoIP, emphaticaly researches on the mobility management for VoWLAN terminal, and basing on the existing protocols proposes a new solution to mobility management on the basis of the existrg protocols related.
