5G System; Interworking between 5G Network and external Data Networks; Stage 3
The present document defines the stage 3 interworking procedures for 5G Network interworking between:
a) PLMN and external DN; and
b) PLMN and PLMN.
The stage 2 requirements and procedures are contained in 3GPP TS 23.501 [2] and 3GPP TS 23.502 [3].
For interworking between 5G PLMN and external DNs, the present document is valid for both 3GPP accesses and non-3GPP accesses.
