Mobility parameter estimation for the optimization of personal paging areas in PCS/cellular mobile networks

Abstract

We formulate the optimum personal paging area problem as an interval estimation problem, with an aim to reduce the paging signaling cost by minimizing the size of the paging area. A paging algorithm is developed to set-up the optimal one-step paging area that contains the locations of a mobile user with a high probability and thus to gain a coverage that is matched to the user's time-varying mobility pattern. With a particular mobility model, the effects of the user's mobility characteristics and the system parameters on the performance of the paging procedure are investigated.
