5G System Overview - 3GPP
Two deployment options are defined for 5G: the "Non-Stand Alone" (NSA) architecture, where the 5G Radio Access Network (AN) and its New Radio (NR) interface is used in conjunction with the existing LTE and EPC infrastructure Core Network (respectively 4G Radio and 4G Core), thus making the NR technology available without network replacement.

一、5G Architecture Options5G架构选项. 最初，在3GPP讨论中考虑了所有可能的聚合和核心 网络组合 ，共有八个架构选项，但随着工作的推进，以下两个主要架构选项脱颖而出，二者在时序上略有不同。 选项3：该架构选项将LTE作为连接锚点，并通过现有的EPC进行连接 ...
System architecture milestone of 5G Phase 1 is achieved - 3gpp.org
2018年1月6日 · The 5G system architecture allows for serving both Access Networks by the same AMF and thereby also for seamless mobility between those 3GPP and non-3GPP accesses. The separated authentication function together with a unified authentication framework allow to customize the user authentication according to the needs of the different usage ...

This paper explores the 3GPP 5G network architecture from release 15 phase 1 and how this will evolve with the introduction of next generation core (NGC) network. The paper starts with a discussion about interworking between LTE and 5G then explores spectrum topics before presenting a detailed view of the end to end 5G network architecture ...
3GPP standards are structured as Releases which represent an evolving set of functionalities. 3GPP TS 23.501: "System Architecture for the 5G System; Stage 2". 3GPP TS 38.401: "NG-RAN; Architecture description". 3GPP TS 33.501: "Security Architecture and …
5G Architecture | part of 5G Technology: 3GPP Evolution to 5G …
This chapter presents an overview of the different 5G architectures and then covers in more details the radio access network (RAN) architecture and interfaces as well as the 5G Core (5GC) network with key elements and functionalities.
Network slice is a logical network serving a defined business purpose or customer, consisting of all required network resources configured together. It is created, changed and removed by management functions. The 5G architecture is defined as service-based and the interaction between network functions is represented in two ways.
