Abstract

In this paper we propose efficient mobility management using Dynamic Location Register (DLR) method, which is efficient for smaller cell and more frequent terminal moving in boundary cell in IMT-2000 networks. Whenever a terminal moves to another Registration Area (RA), Location Register (LR) circle change dynamically, and the terminal can track location by querying DLR of current terminal when a call originate. The proposed scheme reduces location traffic compared with IS-95 standard.
