A Timer-based Multilayer Location Management Strategy for PCS Networks - Universal Personal Communications Record, 1997. Conference Record., 1997 IEEE 6th International Co

In this paper, we propose a location management strategy that minimizes the radio bandwidth cost for paging and location update. The proposed strategy uses the concept of multilayer and is based on the timer-initiated location update and 3-step paging. The system assigns an optimal layer number to a mobile terminal according to the user’s mobility pattern and call arrival rate. The mobile terminal performs location update when the timer expires where a simple algorithm to calculate the timeout value is used. We compare the proposed strategy with other competitive ones in terms of the cost of radio bandwidth for paging and location update. Simulation results are provided to demonstrate the costeffectiveness of the proposed strategy under various scenarios.
