【摘要】：为了满足未来移动网络蜂窝小、切换频繁、支持规模用户和多媒体应用的需求,对位置预测与越区切换进行深入分析,提出了基于位置预测的越区切换方案HDLP(Handover Decision based on Location Prediction),其基本思想是:(1)从移动用户的大量历史移动轨迹数据中挖掘频繁轨迹;(2)根据挖掘出的频繁轨迹集合生成运动规则;(3)将运动规则运用于判决蜂窝移动通信的越区切换中。对所提算法进行仿真的结果表明,与传统的切换方案相比较,本算法减少了不必要的越区切换次数,降低了错误切换率,提高了切换的准确率,进而在一定程度上降低了通信代价,提高了通信系统的容量以及QoS。
[Abstract]:In order to meet the needs of mobile network in the future, such as small cellular, frequent handoff, large scale users and multimedia applications, the location prediction and handoff are deeply analyzed. In this paper, a handoff scheme based on location prediction is proposed. The basic idea of HDLP Handover decision based on location prediction is: 1) Mining frequent tracks from a large amount of historical track data of mobile users. Then the motion rule is applied to the handoff of decision cellular mobile communication. The simulation results of the proposed algorithm show that compared with the traditional handoff scheme, the proposed algorithm reduces unnecessary handoff times, reduces the rate of error handoff, and improves the accuracy of handoff. Furthermore, the communication cost is reduced to a certain extent, and the capacity and QoS of communication system are improved.
