F.5.1 General

The Diameter load control mechanism is an optional feature over the SWa interface.

It is recommended to make use of the IETF RFC 8583 [54] over the SWa interface where, when applied, the untrusted non-3GPP access network shall behave as a reacting node and the 3GPP AAA server as a reporting node.

F.5.2 3GPP AAA server behaviour

The 3GPP AAA server behaviour is the same as described in clause F.3.2 for STa by replacing:

– trusted non 3GPP access network by untrusted non 3GPP access network;

– STa by SWa.

F.5.3 untrusted non-3GPP access network behaviour

The untrusted non-3GPP access network behaviour is the same as described in clause F.3.3 for STa by replacing:

– trusted non 3GPP access network by untrusted non 3GPP access network;

– STa by SWa.
