摘要
针对当前3G网络的发展和无线局域网(Wlan)的兴起,研究了Wlan和3G网络的集成架构和混合异构网络的垂直切换管理。引入Mobile IP技术来达到无缝漫游,同时提出了多接入网络环境下检测Wlan信号强度的异构网间切换方法,并根据延时和中断时间来分析切换方法的性能。试验结果表明该切换方法能够及时有效地改进异构网络的切换效率。
With the development of the 3G network and Wlan,studying the inter-working architecture between Wlan and 3G network,and the handoff management in hybrid heterogeneous networks is very necessary.Then Mobile IP has been considered as the most suitable technology for achieving seamless roaming,the inter system handoff method based on measuring the power of Wlan signal in multi-access network environments has been proposed,and the performance of handoff method in terms of delay and interruption time has been analyzed.
