4.1 Task 1: UE connecting to the new TNAP within the same TNGF p. 9

Solutions for KI4 in TR 33.887 are reproduced in the present document.

Here is the architecture diagram for UE moving from TNAP1 to TNAP2, connected via the same TNGF.

4.2 Task 2: AUN3 device connecting to a new 5G-RG under the same W-AGF p. 9

The AUN3 device does not support NAS over non 3GPP Access and connect to 5GC via 5G-RG. 5G-RG creates NAS Registration on behalf of AUN3 device. Authentication and key hierarchy are defined in clause 7B-7 of TS 33.501, and Annex Z. The FN-RG is not in the scope of this study.

4.3 Task 3: N5CW device connecting to a new TWAP under the same TWIF p. 10

The N5CW device does not support NAS over non 3GPP Access and connect to 5GC via TWIF. TWIF creates NAS Registration on behalf of N5CW device. Authentication of N5CW device via trusted WLAN is defined in clause 7A.2.4 of TS 33.501.

Here is the architecture diagram for N5CW moving from TWAP1 to TWAP2, connected via the same TWIF.

4.4 Task 4: UE connecting to a new WLAN AP connected via the same NSWOF p. 11

Here is the architecture diagram for UE moving from one WLAN to another WLAN, connected via the same NSWOF as defined in Annex S of TS 33.501.

Copy of original 3GPP image for 3GPP TS 33.702, Fig. 4.4-1: UE moves from WLAN AP to another WLAN AP connected via the same NSWOF
