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.

본 논문은 모바일 멀티미디어 서비스를 지원하기 위하여 트랙픽 수용 용량을 극대화하기 위한 방법을 제시한다. 핸드오프 세션을 위하여, 연관된 마이크로 셀들의 수에 따라서 매크로셀의 예약 자원의 수를 동적으로 조정하는 새로운 자원 예약 방법을 제안한다. 제안된 기법은 마이크로셀에서 서비스 가능한 세션의 수를 증가시킬 수 있으며 블록킹율을 현저히 줄일 수 있었다. 따라서 제안된 시스템은 매크로셀에서 세션의 수가 증가할수록 성능이 최적화된다.
