CDMA2000 Ev-Do与WLAN的无缝融合与垂直切换

Seamless Convergence and Vertical Handover between CDMA2000 Ev-Do and WLAN

异构网络无缝融合是未来网络发展的趋势,异构网间的垂直切换则是实现网络无缝融合的关键技术之一。本文针对CDMA2000 Ev-Do网络与WLAN的特点,提出基于移动IP的无缝融合网络结构,并在此基础上提出基于WLAN信号强度的垂直切换方法。

Seamless convergence between heterogeneous networks is the trend of future network development.Vertical handover between heterogeneous networks is one of key technologies for seamless convergence.According to characteristics of CDMA2000 Ev-Do and WLAN,a seamless convergence network structure based on mobile IP is proposed and a vertical handover method based on power of WLAN signal is proposed too.
