基于Mobile IPv6的3G-WLAN网络切换策略研究

3G移动通信系统可以满足用户随时随地更快速的传输多媒体应用与实时性服务的需求,而IEEE的802.11无线网络则可以为用户提供涵盖范围较小、高速的数据传输环境。因此将两种传输技术结合为用户提供快速无缝接入的通信能力,并能在这两种传输技术间快速的切换,有着重大的现实意义。考虑到无线传输的环境中,用户对移动性的需求较高,因此本文以3GPP制定的3G与WLAN整合架构为基础,提出一种基于移动IPv6的异构网络快速切换策略,以减少用户在移动过程中所造成的服务中断和数据包丢失问题。

Research on Mobile IPv6 based 3G-WLAN Handoff Strategy

The third generation communication system can satisfy the requirement of anytime,anywhere and faster multimedia application transmission and real-time service.IEEE 802.11 can provide short distance coverage,high speed wireless network.The seamless integration and fast handoff between 3G and WLAN has important realistic significance.In wireless transmission environment,user has high demand for mobility.In this paper,we propose a mobile IP v6 based fast handoff strategy for heterogeneous network,which is based on the 3G-WLAN internetworking architecture.The proposed scheme can effectively improve the service continuity and packet dropping problem.
