1 Scope p. 5
The present document describes the applicability of NG Application Protocol (NGAP) messages and procedures, defined in TS 38.413, to non-3GPP access. A general description for non-3GPP access can be found in TS 23.501, TS 23.502, and TS 23.316.
2 References p. 5
The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
- References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
- For a specific reference, subsequent revisions do not apply.
- For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

4 Principles for the use of NGAP for non-3GPP access p. 5
4.1 General p. 5
TS 23.501 specifies the NGAP used between the Non-3GPP access network node and the AMF. The Non-3GPP access network node is either a Non-3GPP InterWorking Function (N3IWF), or a Trusted Non-3GPP Gateway Function (TNGF), or a Trusted WLAN Interworking Function (TWIF), or a Wireline Access Gateway Function (W-AGF). NGAP is used as specified in TS 38.413 with clarifications or additions as specified in clause 5.

5.2 NGAP messages used for non-3GPP access p. 7
5.3 Exceptions for NGAP message contents and information element coding when used for non-3GPP access p. 8
