摘要
本文针对多模终端控制智能家居系统的泛在性,将垂直切换技术用到智能家居控制系统中,介绍了一种异构网络垂直切换方案。该方案的关键是针对多模终端的移动性与位置,将异构网络间垂直切换划分为近程端切换与远程端切换。近程端切换方法解决了多模终端由WLAN或WCDMA网络向Zigbee网络切换的终端认证与丢包问题;远程端切换方法通过移动自适应的垂直切换算法,为多模终端选择最佳接入网络,提高了智能家居系统远程控制的实时性。
Aimed at the need of the ubiquitous control of smart home system by multi-mode terminal, this paper uses vertical handoff in the current remote control system and introduces a heterogeneous wireless vertical handoff solution. The key point of this solution is that vertical handoff is divided into near-end handoff and far-end solution, considering the terminal's mobility and position. The near-end handoff solves the problem of terminal authentication and packet loss when changing from WLAN or WCDMA to Zigbee. The far-end handoff provides a best network and can improve the real-time control for multi-mode terminal visiting smart home system by mobility-adaptive handoff algorithm.
