3GPP 23.501 v20.2.0 — the document's own text
4.2.8.5.4 Reference Points
Taught in 10. Radio, Wi-Fi, cable — every way in (The 5G system architecture, in depth), 7. Roaming, other accesses, the edge and the outside (The 5G system architecture, overview).
The Yt' and Yw reference points are both outside the scope of the 3GPP specifications. The Yt' reference point transports WLAN messages (e.g. IEEE 802.11 messages), while the Yw reference point:
- Shall be able to transport authentication messages between the TNAP and the TWIF for enabling authentication of a N5CW device;
- Shall allow the N5CW device to request and receive IP configuration from the TWIF, including an IP address, e.g. with DHCP.
- Shall support the transport of user-plane traffic for the N5CW device.
The N1, N2 and N3 reference points are the same reference points defined in clause 4.2.7.
