A common core network is the one of main architectural principles in 3GPP 5G System which has common interfaces with different multiple accesses. 3GPP 5G System Phase 1 (Release 15) supports Untrusted Non-3GPP access as well as 3GPP access with common interfaces. Non-3GPP Interworking Function (N3IWF) has been defined to interface with a UE and a core network for supporting Untrusted Non-3GPP access in 3GPP Release 15. However, interworking with Trusted Non-3GPP access is under study to be completed in 3GPP 5G System Phase 2 (Release 16). Therefore, this paper proposes a Trusted Non-3GPP access network architecture and related signaling procedures, and then the implementation based on the proposal shows how to interwork between Trusted Non-3GPP access and the 5G core network. In our proposal, N3IWF can interwork with either Untrusted or Trusted Non-3GPP access without any architectural modification or addition of 3GPP 5G system Phase 1.

The 3GPP (3rd Generation Partnership Project) mobile communication standard has emerged as a leading standard in the market over the past 20 years, driving continuous development in protocol stacks and libraries that support the standard within simulation software for communication network research. We summarize and analyze seven communication network simulators that support the 3GPP standard specifications related to core network technologies. Through comparisons, we aim to offer valuable insights for researchers and engineers engaged into research and development related to mobile communication networks based on 3GPP standards. Our findings can provide assistance for making informed decisions on simulator selection.

유럽지역에서의 현재 및 차세대 이동통신의 규격화를 추진하고 있는 3GPP(3$^{rd}$ generation partnership project)의 경우, 부족한 단말의 주소 및 네트워킹의 향상성을 위해 적극적으로 IPv6의 도입을 추진하고 있는 상황이다. 한편 IPv6 자체의 규격은 IETF(Internet Engineering Task Force)에서 진행하고 있는데, 현재 상황의 경우 3GPP에서 IPv6할당의 규격은 IETF의 규격과 완전호환이 되어 있지않아 IETF가 권고안을 마련한 상태이다. 본 논문은 이러한 상태에서 IETF의 권고안을 만족하는 3GPP네트워크에서의 IPv6주소 할당 방식을 제안한다.

USIM(UMTS Subscriber Identity Module) technology that accept 3GPP(3rd Generation Partnership Project) standards for information security supports security function in 3GPP. Supported security functions of USIM are confidentiality of user identity, mutual authentication and key agreement between end user and network, confidentiality of user data and data integrity. It is very important technology in wireless network. It makes secure environment that user and service provider can use securely mobile service in network. In this paper, design and implementation USIM security module that supports common network access method and authentication protocol in 3GPP and WLAN(Wireless LAN) and AAA (3A-Authentication Authorization Accounting) server system based RADIUS.

3GPP(3rd Generation Partnership Project) NDS(Network Domain Security)에 관한 표준화 제정은 특성상 IETF와의 협의를 통하여 최근에 비교적 활발히 이루어지고 있다. 차세대 이동통신의 등장과 인터넷의 발달로 인하여 여러 가지 형태의 네트워크가 존재하게 되고 또한 다양한 프로토콜과 메커니즘이 사용됨에 따라, 무선 구간에서의 안전한 액세스 외에도 유선구간에서의 정보보호 역시 중요한 문제로 대두되고 있다. 본 고에서는 3GPP 네트워크 도메인에서의 정보보호에 관하여 최신 릴리즈 5 버전을 중심으로 stage 2 수준으로 분석을 하였다.

보안은 5G 이동통신 네트워크의 성공적인 정착을 위한 필요충분조건이다. 5G 보안의 중요한 표준으로 3GPP (3rd Generation Partnership Project)의 보안 담당 워킹그룹인 SA3는 3GPP 5G 보안구조를 제시하였다. 특히, 3GPP 5G 보안구조는 Extensible Authentication Protocol (EAP) 인증 프레임워크를 채택함으로써 이기종의 다양한 인증 기법과 자격증명을 용이하게 포용할 수 있는 유연성을 갖추었다. 서비스 융합 네트워크를 지향하는 5G의 비전을 고려할 때, EAP 인증 프레임워크는 보안측면에 있어서 매우 중요한 전략이라고 볼 수 있다. 따라서, 본 논문에서는 3GPP 5G 보안구조를 위한 EAP 인증 프레임워크를 고찰한다. 이를 위해, 1차 인증을 위한 EAP 기반의 인증 프로토콜 EAP-AKA'을 면밀히 검토하면서 1차 인증에서의 EAP 인증 프레임워크 적용방안을 분석한다. 아울러, 2차 인증을 위한 EAP 인증 프레임워크의 적용과 네트워크 슬라이싱 (Network Slicing)과의 연동을 살펴본다.

In this paper, we propose a USIM-based Authentication Scheme for 3GPP Network Access. The proposed scheme improves the problems of existing authentication protocol in 3GPP Network such as sequence number synchronization problem, the storage overhead of authentication data, and bandwidth consumption between Serving Network and Home Network. Our proposal is based on the USIM-based Authentication and Key Agreement Protocol that is defined in 3GPP Specification. In our scheme, mobile nodes share a SK with Serving Network and use a time stamp when mobile nodes are performing an authentication procedure with Serving Network. By using time stamp, there is no reason for using sequence number to match the authentication vector between mobile nodes and networks. So, synchronization problem can be solved in our scheme. As well as our scheme uses an authentication vector, the storage overhead of authentication data in Serving Network and bandwidth consumption between networks can be improved.

This paper focuses on advanced receiver for interference suppression or cancellation from neighbor cells in the 3GPP Rel-12 standard. From UE (User Equipment) perspective, the advanced receiver which can manage inter-cell interference of adjacent cell is required to support and manage fast-growing wireless data traffic. In 3GPP standard, NAICS which is one of approaches to improve SINR and receiver performance by directly suppression or cancellation of data (PDSCH) and control (PDCCH) signal from interference cells is discussed. In this paper, we briefly introduce the concept and candidate receivers for NAICS (Network Assisted Interference Cancellation and Suppression) based on 3GPP Rel-12 standard, and simulation results for basic NAICS receiver performance are provided.
