Related specs in 3GPP TS 29.273: <pre> * 7.1.2.2 Authorization Procedures * 7.2.2.1.3 Diameter-AA-Request (AAR) Command ePDG --> AAA * 7.2.2.1.4 Diameter-AA-Answer (AAA) Command ePDG <-- AAA </pre> This is triggered by "re-authentication procedure as described in clause 7.2.2.4". That basically means that: 1- HSS --> -> AAA-server: Push-Profile-Request (implemented, see #6404) 2- AAA-server --> -> ePDG: Re-Authorization Request (RAR), 7.1.2.5 (implemented, see https://gerrit.osmocom.org/c/erlang/osmo-epdg/+/36305) At that point, in the ePDG we need to send AAR to the AAA, see 7.1.2.5: <pre> Upon receiving the re-authorization request, the ePDG shall immediately invoke the authorization procedure specified in 7.1.2.2 for the session indicated in the request. This procedure is based on the Diameter commands AA-Request (AAR) and AA-Answer (AAA) specified in IETF RFC 4005 [4]. Information element contents for these messages are shown in tables 7.1.2.2.1/1 and 7.1.2.2.1/2. </pre>
