The personal communications services (PCS) systems provide ubiquitous and customized services. The key issue, which affects the performance of the whole system, is the location management. Current systems group cells into location regions to reduce the location management cost which includes the location tracking cost and the registration cost. In this paper, by considering users' movement behaviors, four strategies are proposed to derive location regions. These strategies attempt to simultaneously reduce the location tracking cost and the registration cost. Simulations are performed to compare the performance of these methods with the existing strategies to show the superiority of our approaches.
