Abstract

This paper proposes enhanced designs of global service logic and information flow for the mass-call based IN service, which increase call completion rates and optimize the resource in joint wired and wireless networks. In order to hanve this logic implemented, we design a Dynamic Queue Manager(DQM) applied to the call queuing service feature in the Service Control Point(SCP). In order to apply this logic to wireless service subscribers as well as wired service subscribers, the service registration flags between the Home Location Register(HLR) and the SCP are managed to notify the DQM of the corresponding service subscribers’ mobility. Hence, we present a dynamic queue management mechanism, which dynamically manages the service group and the queue size based on M/M/c/K queueing model as the wireless subscribers roam the service groups due to their mobility characteristics. In order to determine the queue size allocated by the DQM, we simulator and analyze the relationship between the number of the subscriber’s terminals and the drop rate by considering the service increment rate. The appropriate waiting time in the queue as required is simulated according to the above relationship. Moreover, we design and implement the DQM that includes internal service logic interacting with SIBs(Service Independent building Blocks) and its data structure.

본 논문은 유무선 통합망 환경하에서 대량호에 근거한 지능망 서비스의 호 완료율을 증가시키고 자원을 최적화하기 위한 정보 흐름 및 총괄서비스 로직을 설계한다. 이 로직을 구현하기 위하여 지능망 서비스제거에 호대기 서비스 특징을 적용하기 위한 동적 큐 관리자를 제시하는데, 이것을 유선 가입자뿐만 아니라 이동 단말을 소유한 무선 가입자에게도 적용하기위해 홈위치등록기와 서비스제어기간에 해당 서비스 가입자들의 이동성을 큐 관리자에게 통보하기 위한 서비스 등록 여부 프래그를 관리한다. 따라서, 이동 서비스 가입자가 로밍함에 따른 동적 서비스 그룹핑을 수행하고 M/M/c/K 큐잉 모델에 근거한 큐 길이를 동적으로 관리하여 자원을 최적화 할 수 있는 동적 큐 관리 메커니즘을 제안한다. 동적 큐 관리자에 의해 할당된 큐 길이를 결정하기 위해 서비스 증가율에 따른 가입자 단말 수와 실패율간의 관계 및 그에 따른 큐에서의 적정 대기 시간을 시뮬레이션 및 분석한다. 또한, 동적 큐 관리자를 구성하는 내부 서비스 로직과 SIB들간의 상호동작 및 자료 구조를 설계 및 구현한다.
