Wa

between WLAN Access Network and 3GPP AAA Proxy / Server

specified from Rel-6
Source: TS 23.002, clause 6a.9.2

The AAA protocol on this reference point is used to transport authentication, authorization and charging data.

For more information see TS 23.234.

Wd

between 3GPP AAA Server and 3GPP AAA Proxy

specified from Rel-6
Source: TS 23.002, clause 6a.9.3

The purpose of the protocols crossing this reference point is to transport authentication, authorization and related information.

For more information see TS 23.234.

Wg

between 3GPP AAA Server / Proxy and WAG

specified from Rel-6
Source: TS 23.002, clause 6a.9.4

The functionality of this reference point is to provide information needed by the WAG to perform policy enforcement functions for authorised users and to transport per-tunnel based charging information from the WAG to the AAA Proxy in roaming scenarios.

Wi

between PDG and PDN (Packet Data Network)

specified from Rel-6
Source: TS 23.002, clause 6a.9.5

This is the reference point between the PDG and a packet data network. It may be an operator external public or private packet data network or an intra operator packet data network, e.g. for provision of IMS services.

Wm

between 3GPP AAA Server / Proxy and PDG

specified from Rel-6
Source: TS 23.002, clause 6a.9.6

The functionality of this reference point is to enable:

The 3GPP AAA Server/Proxy to retrieve tunnelling attributes and WLAN UE's IP configuration parameters from/via Packet Data Gateway
Carrying messages for service authentication and authorization
Carrying authentication data for the purpose of tunnel establishment, tunnel data authentication and encryption.

For more information see TS 23.234.

Wn

between WAG and WLAN Access Network

specified from Rel-6
Source: TS 23.002, clause 6a.9.7

The functionality of this reference point is to force traffic between a WLAN UE and PDG to go through the WAG.

Wp

between WAG and PDG

specified from Rel-6
Source: TS 23.002, clause 6a.9.8

The functionality of this reference point is to transport the Wu reference point protocol data packets.

Wu

between 3GPP WLAN UE and PDG

specified from Rel-6
Source: TS 23.002, clause 6a.9.9

The functionality of this reference point is to establish a tunnel between WLAN UE and PDG and to exchange data packets between WLAN UE and PDG.

Ww

between 3GPP WLAN UE and WLAN Access Network

specified from Rel-6
Source: TS 23.002, clause 6a.9.10

The functionality of this reference point is specified by IEEE and is outside the scope of 3GPP.

Wx

between 3GPP AAA Server and HSS

specified from Rel-6
Source: TS 23.002, clause 6a.9.11

The functionality of this reference point is to enable:

Retrieval of authentication vectors
Retrieval of WLAN access-related subscriber information (profile)
Registration of the 3GPP AAA Server of an authorised WLAN user in the HSS
Indication of change of subscriber profile
Retrieval of online charging / offline charging function addresses from HSS.
Retrieval of service related information

For more information see TS 23.234.
