초록

CDMA시스템에서 서로 다른 종류의 호에 서로 다른 우선권을 할당하는 호 수락제어(CAC: Call Admission Control)기법은 많은 연구가 이루어졌다. 본 논문에서는 사용자의 전체 자원요구량에 근거하여 같은 종류의 호에도 서로 다른 우선권을 할당하는 호 수락제어기법을 제안하고 그 성능을 분석한다. 제안하는 알고리즘은 한 기지국에서의 자원요구량이 아닌 전체 시스템에서의 자원요구량에 근거하여 같은 종류의 호에 서로 다른 우선권을 할당한다. 새로운 호의 호 신청수락여부를 결정할 때 시스템에 충분한 여유용량이 있으면 모든 호를 수락하지만 모든 호들을 받아들일 수 없으면 우선권이 높은 호부터 받아들인다. 분석결과는 제안된 알고리즘이 같은 종류의 호에 서로 다른 우선권을 할당하지 않는 알고리즘보다 호 차단확률과 통화품질 저하확률 및 전송부하에서 모두 우수한 성능을 나타냄을 보여준다.

CAC (Call Admission Control) schemes for different service class are studied in many Papers. A novel priority CAC algorithm, which gives priority to a same class call according to the total resource requirements is proposed and analyzed in this paper. The proposed algorithm provides a priority according to the total resource requirements other than only in a base station. If there are efficient residual resources in the system, it will accept all new calls. Otherwise, it will selectively accept these new calls according to the total resource requirements. The results show that the proposed algorithm provides better call blocking probability, outage probability and throughput than the conventional algorithm.
