Since the location update process requires heavy signaling traffics, reducing the location update cost has been a critical research issue. This paper proposes to employ hierarchical structure in PCS networks to reduce the location update cost. The paper also develops analytical models to evaluate the performance of the proposed approach. The evaluation shows that the proposed approach reduces the location update costs by reducing the update rate of the home location register. The reduction of the location update cost becomes larger when the degree of hierarchy is larger, the size of location area is smaller, and the average residual time of mobile users is smaller.
