N2 - In wireless mobile networks, particularly in PCS networks, new calls to a portable may be lost due to the incorrect location information in the mobility database, which leads to an database failure. Such database failure can be recovered either through the portable's registration initiation, the deregistration when it cross the location area boundary or the active location update. In this paper, we analyze the active location update scheme under several different mobile traffic distributions for the failure restoration. We present analytical results for cost analysis. We find that under certain conditions there exists an optimal choice of location update period to minimize the total cost which represents the tradeoff between the location update and call loss. Our results provide a general framework for evaluating active database failure recovery schemes in wireless networks.
