Abstract

This paper proposes a scheme to maximize traffic capacity for supporting mobile multimedia services. For a handoff session, we suggest a novel resource reservation scheme to adjust the number of reserved resources in macrocell, depending on the number of saturated microcells. The proposed schemes are able to accommodate much more mobile sessions in the microcell and significantly reduce the blocking probability in the macrocell at the expense of the small increment of a forced termination in the microcell. Therefore, our system is more flexible to the increase of traffic in macrocell.
