| 摘 要： | 3G网络和无线局域网融合是下一代移动通信的发展趋势, 在两种异构网络之间实现智能切换是融合网络的关键技术. 针对多属性垂直算法的分析, 提出了一种自适应的多属性垂直切换算法. 该算法根据请求业务的不同特性和当前网络状态动态调整层次分析法(analytic hierarchy process, AHP)的参数, 从而使得切换算法具有较低的阻塞率和时延, 以及较高的带宽使用率. 最后对该算法进行了性能仿真, 验证了其有效性.

| Abstract: | Integration of 3G networks and wireless local area networks is a trend of the next generation mobile communication. Vertical handoff is the basic requirement for convergence of different access technologies, and therefore receives much attention from the academia and industry. This paper analyzes tradition algorithms and proposes a new algorithm that can adjust parameters according to the business and network status. Simulation results show that the proposed algorithm has low blocking rate, low average time delay, and high bandwidth usage. |

| Keywords: | analytic hierarchy process (AHP) heterogeneous network self-adapt vertical handoff |
