The wireless communication network is evolving toward the Personal Communication System to provide various multimedia services. In order to accomplish this goal, the effective schemes are required which can dynamically utilize the limited wireless resources based on traffic characteristics of each services. This paper proposes a novel call admission control scheme for the hierarchical macrocell/microcell structured PCS. It is based on the bandwidth reservation procedure performed in the macrocell or neighboring microcell. Its effectiveness is investigated by simulation.
