Abstract

In LTE-Advanced that different networks coexist, it is considered that it is actually difficult to provide service continuity with a procedural and static control method applied to the existing voice service. This research suggests a resource management framework to support the service continuity effectively based on QoS support. In other words, as context information of mobile terminal and base station changes, set-up of related functions such as ISHO, cell selection, source allocation, load control, and QoS mapping is adapted; each function fits into the change, exchanges the process of reorganization, and interacts; these actions go toward to satisfy service continuity. For this aim, the sequence diagram between the function modules for supporting four kind of ISHO is described and then a scenario for ISHO is considered.

상이한 망이 공존하는 LTE-Advanced에서 기존 음성 서비스에 적용된 절차적이고 정적인 제어방식으로는 서비스 연속성을 효과적으로 지원하는 것은 현실적으로 어렵다고 여겨진다. 본 연구에서는 QoS 지원을 기반으로 서비스 연속성을 효과적으로 지원하기 위한 자원 관리 프레임워크를 제시하고자 한다. 제안된 자원 관리 프레임워크는 이동 단말기 및 기지국의 상태 정보 변화에 따라 관련 기능-ISHO, 셀 선정, 자원 할당, 부하 제어, QoS 매핑 등-의 설정을 동적으로 제어하고, 각각의 기능들이 변화에 적응하여 조정되고 재구성하는 과정을 주고받으면서 서비스 연속성을 만족시키기 위하여 상호 작용한다. 이를 위하여 4 종류의 ISHO를 지원하기 위한 각 모듈간의 연계 순서도를 기술하고, ISHO 시나리오가 고려된다.
