Figure 8.2.4-1: Control Plane before the signalling IPsec SA is established between UE and N3IWF
Figure 8.2.4-2: Control Plane after the signalling IPsec SA is established between UE and N3IWF
Large NAS messages may be fragmented by the
"inner IP"
layer or by TCP.

In the above
Figure 8.2.4-1
,
Figure 8.2.4-2
and
Figure 8.2.4-3
, the UDP protocol may be used between the UE and N3IWF to enable NAT traversal for IKEv2 and IPsec traffic.
The
"signalling IPsec SA"
is defined in
clause 4.12.2 of
TS 23.502
.
