Capacity analysis of stepwise paging scheme for next generation mobile communication systems

The location registration scheme is one of the most important issues in cellular systems, especially in microcellular systems. In this paper, we introduce a hybrid stepwise paging scheme with small paging areas in one large location area, to reduce the location registration signals. To compare the performances of schemes such as zone-based location registration schemes with small location areas in one large location area and the proposed stepwise paging scheme, we perform some experiments with variant call arrival rates and velocities. The results show that the proposed hybrid scheme reduces the signaling cost for users with high velocity and with low incoming call arrivals. Next, we investigate the performance in a real world environment. This result shows that the proposed scheme can eliminate the inefficiency by reducing the updating signals of users with high velocity. The proposed hybrid stepwise paging scheme is better than traditional zone-based location registration schemes for the next generation mobile communications systems
