3GPP 24.501 v20.0.0 — the document's own text

8.2.7.26 Non-3GPP NW policies

Taught in 4. Inside TS 24.501, the document at the centre (CT1 — the group that writes what your phone says, overview).

The AMF shall not include this IE during a registration procedure over non-3GPP access.

This IE is included if the network needs to indicate whether emergency numbers provided via non-3GPP access can be used to initiate UE detected emergency calls (see 3GPP TS 24.302 [16]). If this IE is not included then the UE shall interpret this as a receipt of an information element with all bits of the value part coded as zero.

NOTE: In this version of the specification, this IE is applicable in case the UE is connected to a PLMN using an ePDG as specified in 3GPP TS 24.302 [16].
