Abstract

통신 기술의 발달로 인하여 고정망 뿐만 아니라 이동망에서도 지능망 서비스를 제공하는 것이 중요하게 생각되고 이에 대한 많은 연구가 진행중이다. 이 논문은 이동망에서의 지능망 서비스를 효율적으로 제공하기 위한 네트워크 모델을 제안한다. 제안하는 모델에서는 MSC/SSP와 SCP/HLR 사이의 두 가지 신호 구조를 고려한다. 이러한 모델에서 지능망 서비스를 제공하는 것이 효율적임을 보이기 위하여 먼저 VLR을 사용한 지능망 서비스의 제공 방안을 제시한 후, 두 가지 모델에서의 지능망 서비스 관리에 관한 성능을 분석해 보고자 한다. 이러한 방법은 SCP에 저장된 지능망 서비스 프로파일들을 VLR로 다운로드 하여 사용자로부터의 지능망 서비스 요청시에 SCP로의 연결을 줄이는 것이다. 제시한 방법은 SCP/HLR의 부하를 감소시켜 지능망 서비스 관리면에서 IMT-2000 보다 훨씬 더 나은 성능을 보인다.Abstract As the communication technology has been developed, it is necessary to provide the IN service in the mobile network as well as the fixed network and many researches are in progress. In this paper we propose the network model to efficiently provide IN service in the mobile network. There are two signaling architectures between MSC/SSP and SCP/HLR. To show that it is efficient to provide the IN service in the proposed model, we propose IN service provision method using VLR and analyze the performance of IN service management in two architectures. These methods are to download the IN service profiles that are saved in SCP to VLR and to decrease the connection to SCP when the user requests the IN service. The proposed methods show that the load of SCP/HLR is decreased and our method is better than IMT-2000 in the aspect of IN service management.
