초록
본 논문에서는 5G 네트워크 슬라이싱에 대해서 분석하고 5G 이동 통신망에서의 효율적인 네트워크 슬라이스 설정 방안을 제안한다. 5G 이동 통신망에서 네트워크 슬라이싱은 네트워크 슬라이스 인스턴스 정보에 기반하여 구분되고 수행된다. 단말과 네트워크 간의 네트워크 슬라이스 인스턴스 정보가 상호 일치하지 않는 경우, 단말의 PDU 세션 연결 요청 실패에 따른 불필요한 시그널링 오버헤드가 발생한다. 본 논문은 이러한 문제를 해결하기 위해서, 두 가지 효율적인 네트워크 슬라이스 설정 기법, 단말 기반 ENSC(Efficient Network Slice Configuration) 기법과 네트워크 기반 ENSC 기법을 제안한다. 제안하는 두 가지 기법들은 신속한 단말과 네트워크 간의 최신 변경업데이트된 네트워크 슬라이스 정보를 제공 설정 수행하게 되어, 기존 방안과 비교하여 배터리리소스 효율성을 향상시키고 불필요한 시그널링 오버헤드를 최소화할 수 있다.
Abstract
In this paper, we analyze 5G network slicing and propose an efficient network slice configuration method in 5G mobile networks. Network slicing can be identified and performed based on the network slice instance information in 5G mobile networks. In case of discordance between the UE’s network slice instance information and the network’s one, the unnecessary signalling overhead occurs, when the UE’s PDU Session Establishment request to the network fails. To solve this problem, this paper proposes two efficient network slice configuration methods, the UE-based ENSC(Efficient Network Slice Configuration) method and the Network-based ENSC method. The proposed schemes perform the prompt the configuration and provision of the updated network slice instance information between the UE and network and improve battery and resource efficiency and minimize unnecessary signalling overhead compared to existing methods in 5G mobile networks.
