Location tracking is used to keep track of the location information of a mobile terminal in an idle state for a call setup between mobile terminals. In this paper, we introduce a new location tracking strategy that utilizes spatial locality to have better performance than a movement based location tracking strategy. We reduce a lot of unnecessary location updates by updating the location information of a mobile terminal using the virtual movement path, which is generated after removing spatial localities in the actual movement path. Simulation results show that the proposed strategy greatly reduces the overall location tracking cost.
