摘要
对移动用户在异构网络环境下的切换触发时间选择问题进行了研究。首先对移动终端触发切换的时间选择问题进行了理论分析，找到了最佳切换触发时间所应满足的条件。然后在切换耗时估计和接收信号强度预测的基础上，提出了一种预测最佳切换触发时间的算法。仿真结果表明，本算法能够有效降低用户的分组丢失概率和切换失败概率。
Abstract
The handover trigger time selection problem for mobile user in the heterogeneous networks environment was discussed.Firstly
theoretical analysis of the handover trigger time selection was presented and the constraint which the optimal handover trigger time should satisfy was obtained.Then
an algorithm was proposed to predict the optimal handover trigger time based on the estimation of handover delay and the prediction of received signal strength.Simulation results show that this algorithm can effectively reduce the packet loss ratio and the probability of handover failure.
