오늘은 NSA와 SA의 차이점에 대해 세부적으로 리뷰한다.
앞서 언급한 듯이 SA로 가려면 Option 2 구조를 선택해야한다.

5G NR Architecture Overview
오늘은 5G 네트워크 구조에 대해 살펴보자. 앞서 언급했듯이 LTE와 5G는 공존할 수 밖에 없는 구조 이다. 앞서 언급했다 싶이 LTE 기지국(eNB)와 5G 기지국(gNB)을 Signal과 Data User Plane을 사용하는 방식

Option2 구조에 대해서는 5G NR Architectrue Overview를 참고 하시길 바란다.
The major differences between the different NR deployment options, as specified in the previous section. Option 1 as referred to as legacy LTE and option 5 which is least likely to be adopted are excluded. Options 3, 4 and 7 relying on the existing LTE network require an alignment with LTE network, so sub- 6GHz bands are recommended for NR deployment. In addition, they need to interwork with LTE tightly through dual connectivity such as EN-DC/NE-DC or NGEN-DC. However, NR deployment using option 2 is free to configure the 5G network. For example, mid-band can be used for wide NR coverage and mmWave can be utilized for hot-spot in urban area. Option 3 can provide limited 5G service like eMBB due to EPC, but options 2, 4 and 7 can provide full 5G-specific services. Although option 4 and option 7 belong to NSA category according to the 3GPP, it is reasonable to regard them as SA because they can provide 5G-specific services due to the architecture that contains NR RAN as a MN and 5GC.
