5G Core Architecture

5G Core Architecture:

This article describes the architecture for the 5G System. The 5G architecture is described as service-based and the interplay between network functions is represented in two ways.

·         A service-primarily based illustration, where network functions (e.g. AMF) inside the Control Plane enables other authorized network functions access to their services. This representation also consists of factor-to-point reference factors in which necessary.

·         A reference point representation, indicates the interaction exist between the NF offerings within the network functions described by point-to-point reference factor (e.g. N11) between any network functions (e.g. AMF and SMF).
