Section: 4.2.8.5.4 Reference Points
Content: 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.
