Abstract

In LEO satellite mobile communication systems, location management plays an important role for the supporting of global roaming and has great effect on the cost of mobility management. With the zooming satellite mobile users and demands of communications, the diversity of terminal is increased and the speed range among terminals is also proliferated. The speed of terminals is a crucial parameter for the design of location management strategy. A movement based two tiers paging scheme for LEO mobile satellite system is proposed. Location area and paging area are defined according to the classification of the terminal's speed respectively and one location area is divided into several paging area for smaller quantity of location updating and shorter paging delay. The simulation is performed and the results show the validity of the proposed paging scheme.
