传统上的水平切换处理方法已经应用在同一接入技术的网络中(如无线蜂窝网络)。随着多种异构无线网络的出现,下一代网络必须支持垂直切换技术以保证用户从一个网络切换到内一个网络时仍然保持连接,垂直切换作为多网融合的基础,受到了学术界和工业界的广泛关注。对使用层次分析法进行垂直切换技术的工作原理及应用环境进行了分析,提出同时使用多种切换技术以解决不同环境下的切换问题。
The traditional horizontal handover processing method has been applied to the same access network technology (such as wireless cellular network). With the advent of multiple heterogeneous wireless networks, next-generation networks must support vertical handoff techniques to ensure that users remain connected when switching from one network to the next. As the basis for multi-network convergence, vertical handoff has been well received by academia and industry Community wide concern. Analyzed the working principle and application environment of the vertical handover using AHP, and proposed to use multiple handover techniques simultaneously to solve the handover problem in different environments.
