摘要

异构网络之间的互连是提供“永远在线”连接服务的需求。第四代(4G)移动网络的广泛愿景包括当前无线技术的共存,如WLAN、WiMAX、通用分组无线业务(GPRS)和通用移动通信系统(UMTS)。下一代无线网络(NGWN)面临的主要问题是垂直切换管理。现有的切换管理协议不足以保证对NGWS中的应用透明的切换支持。本文提出了一种基于IEEE 802.21 MIH和移动IPv6的多接口MN垂直切换管理优化方法。

Vertical handover based on IEEE802.21 and Mobile IPv6 in UMTS/WLAN networks
The internetworking among heterogeneous networks is in demand to provide "always-on" connectivity services. A widespread vision of the fourth generation (4G) mobile networks includes coexistence of current wireless technologies such as WLAN, WiMAX, General Packet Radio Service (GPRS) and Universal Mobile Telecommunications System (UMTS). The major problem that faces next generation wireless networks (NGWN) is vertical handoff management. The existing handoff management protocols are not sufficient to guarantee handoff support that is transparent to the applications in NGWS. In this paper we propose an approach based on IEEE 802.21 MIH and Mobile IPv6 to optimize vertical handover management for multi-interface MN.
