Another Two-level Pointer Strategy for Location Management in PCS Networks

Abstract

We propose an auxiliary scheme called another two-level pointer strategy, with a new procedure for updating and locating users who move from place to place while using Personal Communication Service (PCS) networks. The new scheme reduces the cost of registration using the pointer to replace updating a user’s location information to the Home Location Register (HLR) when the user moves to a new registration area (RA). Moreover, to reduce the cost of HLR update, we utilize a local pointer to replace updating the user’s current location information to the HLR upon every Kth pointer forwarding.
