摘　　要：为解决异构无线网络在传输不同类型数据过程中的切换问题,提出了一种基于多业务类型的异构无线网络切换算法。该算法根据传输业务类型的优先级及其实时性,将业务类型分为实时业务和非实时业务。通过对可用带宽、网络时延等判决参数的分析及切换判决参数满意程度的计算,设计出基于多业务类型的异构无线网络切换算法。该算法可以根据不同的业务类型选择最佳的传输网络,改善网络拥堵现象,减少切换时延,充分发挥异构网络的优势。In order to solve the heterogeneous wireless network in different types of data transmission in the process of switch network problems.This paper puts forward a kind of heterogeneous wireless network switching algorithm that based on the business types.The algorithm uses the transfer business types of priorities and its real-time performance,and it can be divided into real-time and non real-time business.Through the analysis of available bandwidth,packet loss rate and delay,and using the switch decision parameter of satisfaction,the heterogeneous wireless network switching algorithm based on the business types is designed.It can choose the best network according to different types of business,which can improve the network congestion phenomenon,reduce switching time delay and give full play to the advantages of heterogeneous network.
