This paper presents a dynamic location area assignment (DLA) algorithm. When a mobile unit (MU) exits a location area, a new location area is assigned based on the time-varying mobility statistics recorded by the MU. The overlapping region of the new and the original location area, and the location area size are dynamically adjusted. For any location area size, the expected dwell time of a MU in the assigned location area is maximized. Numerical examples show that the proposed algorithm outperforms conventional strategies under all mobility scenarios
