The present document defines the Stage 2 system architecture for the 5G System. The 5G System provides data connectivity and services. This specification covers both roaming and non-roaming scenarios in all aspects, including interworking between 5GS and EPS, mobility within 5GS, policy control and charging, and authentication. TS 23.502 contains the stage 2 procedures and flows for 5G System and it is a companion specification to this specification.
