In order to accurately calculate the cost of location management for the wireless cellular network, this paper puts forwards the predictive directional Markov chain as a mobility model based on the two-dimensional hexagon cellular structures. According to the location update model based on the two-steps paging strategy established between two consecutive arrival calls to get the optimal threshold of movement-based location management and the probability distribution of crossing the cell boundary K times on the condition that the incoming calls form a Poisson process and the MT's cell residence time has exponential probability distribution. Then with these given probability distribution we give the optimal two-steps paging strategy. Finally, numerical results show that this strategy outperforms some well-known basic paging schemes.

Key words: location management, location update, two-step paging, cost analysis
