摘要： 针对异构网络环境下紧耦合方式中的网络切换问题,提出一种结合通信业务和运动感知的切换算法。根据终端移动性初步筛选出候选网络集,依据终端多业务特性从候选网络集中选择出最优网络进行切换。在不同业务下与基于运动感知的切换算法进行实验对比,结果表明,该算法既能避免不必要的切换,又能降低切换阻塞率。

Abstract: Aiming at the problem of network handoff in tightly coupled mode under the heterogeneous network,a handoff algorithm combining communication service and motion perception is proposed.According to the mobility of the terminal,this algorithm screens the candidate network set initially,and then tries to find the best network from the candidate network set on the basis of the multi-business features of terminal network for handoff.After the experimental comparison with the handoff algorithm based on the motion perception under different businesses,the results show that the algorithm can avoid unnecessary handoff and reduce the blocking rate of handoff.

Key words: heterogeneous network, communication business, motion perception, seamless handoff, candidate network set
