Velocity-assisted paging in PCS through stochastic modelling of terminal displacement

The authors propose a novel framework for the exploitation of mobile velocity for the optimisation of paging performance in PCS. The focus is on the optimisation of the paging process based on the estimation of terminal displacement from its last known position. This estimation is performed through a stochastic formulation, making use of both the velocity category of the terminal and the velocity category residence time. Simulation results are provided and the proposed method is compared with other paging strategies, indicating certain advantages that together with its very low complexity could make it applicable for both 2G and 3G systems.
