This study considers zone-based registration (ZBR) and distance-based registration (DBR). A mobile station performs location registration whenever the MS reaches a new zone or the specified distance. These two schemes seem to be similar but, in DBR, the mobile station (MS) is in the center of the location area right after location registration differently from in ZBR. In this study, we point out some problems of the previous analysis method and propose an improved analysis method of ZBR and DBR. Using the improved analysis method, we show that the previous analysis includes some problems, and that the performances of two registration methods in our study are enhanced more than in the previous study. This results of this study should be useful to analyze the performance of various location registration schemes.
