下一代异构无线网络中的垂直切换是一个多维度的问题。在这篇文章中，我们提出了一个多维自适应的SINR垂直切换算法（MASVH），它使用的SINR，用户所需的带宽，用户流量成本和参与接入网络的利用率的综合影响，使切换决策的多属性QoS的考虑。仿真结果表明，该算法在提高系统吞吐量和降低丢包率的同时，降低了接入综合无线网络的用户流量开销。
Vertical handoff in next generation heterogeneous wireless networks is a multi-dimensional issue. In this article we propose a multi-dimensional adaptive SINR based vertical handoff algorithm (MASVH) which uses the combined effects of SINR, user required bandwidth, user traffic cost and utilization from participating access networks to make handoff decisions for multi-attribute QoS consideration. Simulation results confirm that the new MASVH algorithm improves the system performance in terms of higher throughput and lower dropping probability, as well as reduces the user traffic cost for accessing the integrated wireless networks.
