%X As continuing growth in traffic volume from users with varying degrees of mobility in wireless networks, a Hierarchical Cellular Structures(HCS)has been suggested.In this paper,the performance of a two-tier microcell/macrocell cellular system with bidirectional call-overflow scheme is studied,where cell selection in hierarchical architecture is based on the velocity of the mobile making the calls.Different from the general layer-classified(macrocell and microcell)analysis,a user-classified(fast and slow)modeling method is developed for evaluating the performance of such systems.The user-classified models consist of a fast user model and a slow user model both of which are simple one-dimension Markov process transition diagrams.Theoretical analysis and numerical evaluation show that the analytical models are reliable.Furthermore,effect of velocity threshold and blocked call repeat phenomenon using the models are examined.
