本文介绍了一种移动跟踪机制，该机制将基于移动的位置更新策略与选择性分页方案相结合，选择基于移动的位置更新是因为其简单。它不要求每个移动终端存储有关所有单元的排列和距离关系的信息，实际上，每个移动终端仅保留访问的单元数量的计数器，当该计数器超过预定义的阈值时执行位置更新，该方案允许在每个用户的基础上动态选择移动阈值，这是可取的，因为不同的用户可能具有非常不同的移动模式。选择性寻呼以增加寻呼延迟为代价，降低了移动终端的定位成本。本文提出了一种在允许的寻呼延迟很小的情况下显著降低位置跟踪成本的选择性寻呼方案，并对所提出的位置跟踪机制引入了一个分析模型，该模型能够捕捉移动终端的移动性和呼入到达模式。分析结果证明了该方案在不同参数下的成本效益。
This paper introduces a mobility tracking mechanism that combines a movement-based location update policy with a selective paging scheme, Movement-based location update is selected for its simplicity. It does not require each mobile terminal to store information about the arrangement and the distance relationship of all cells, In fact, each mobile terminal only keeps a counter of the number of cells visited, A location update is performed when this counter exceeds a predefined threshold value, This scheme allo cvs the dynamic selection of the movement threshold on a per-user basis, This is desirable as different users may have very different mobility patterns, Selective paging reduces the cost for locating a mobile terminal in the expense of an increase in the paging delay, In this paper, we propose a selective paging scheme which significantly decreases the location tracking cost under a small increase in the allowable paging delay, We introduce an analytical model for the proposed location tracking mechanism which captures the mobility and the incoming call arrival patterns of each mobile terminal, Analytical results are provided to demonstrate the cost-effectiveness of the proposed scheme under various parameters.
