1  Scope |R6|Word‑p. 8

The present document defines the stage-3 protocol description for several reference points in the WLAN-3GPP Interworking System.
The present document is applicable to:
  • The Dw reference point between the 3GPP AAA Server and an SLF.
  • The Wa reference point between the WLAN AN and the 3GPP AAA Proxy.
  • The Wd reference point between the 3GPP AAA Proxy and 3GPP AAA Server.
  • The Wx reference point between the 3GPP AAA Server and the HSS.
  • The Wm reference point between the 3GPP AAA Server and the PDG.
  • The Wg reference point between the 3GPP AAA Server/Proxy and the WAG.
  • The Pr reference point between the 3GPP AAA Server and the PNA.

2  References |R6|

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.
