摘要 阐述了具有蜂窝网络结构的个人通信系统中,基于考虑静止概率全向运动模型的动态位置管理。首先介绍了全向运动模型及其改进,使之更加符合实际用户的运动特性;在此基础上,提出了一种新型的以用户为中心的位置区域预测方法,通过计算各小区访问概率并选择其中的极大值,预测出以用户为中心的最佳位置区域;文中还提出仿真算法,并举例说明仿真结果。 This paper addresses the dynamic location management in personal communication systems with cellular network architectures based on all-direction mobility model with stationary probability.Firstly,the all-direction mobility model and its improvement are introduced,making the new model more conformed to the actual mobility characteristic; By using this novel model,a new method of subscriber-centric location area prediction is proposed,then the optimal LA for subscribers by calculating the probabilities of visiting cells and selecting maximum from them is predicted;furthermore,the simulation algorithm and results are illustrated.
