This is the reference point between the 3GPP AAA server and the HLR up to and including Rel 4 and the HSS in Rel 5. The functionality of this reference point is similar to that of the Wx reference point. For more information see TS 23.234.

This is the reference point between the WLAN access network and 3GPP AAA Proxy or Server. The AAA protocol on this reference point is used to transport authentication, authorization and charging data.

This is the reference point between the 3GPP AAA Server and Proxy. the purpose of the protocols crossing this reference point is to transport authentication, authorization and related information. For more information see TS 23.234.

This is the reference point between the 3GPP AAA server/proxy and WAG. It is used 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.

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.

This is the reference point between the 3GPP AAA server/proxy and PDG. 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.

This is the reference point between the WAG and the WLAN access network. It is used to force traffic between a WLAN UE and PDG to go through the WAG.

This is the reference point between WAG and PDG. It is used to transport the Wu reference point protocol data packets.

This is the reference point between the 3GPP WLAN UE and PDG. 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.

This is the reference point between the 3GPP WLAN UE and WLAN access network. The functionality of this reference point is specified by IEEE and outside the scope of 3GPP.

This is the reference point between the 3GPP AAA server and HSS. 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.

This reference point is between the 3GPP AAA Server and the SLF. The prime purpose of the protocol(s) crossing this reference point is to enable the 3GPP AAA Server to find the address of the HSS which holds the subscriber data for a given user identity in a configuration with multiple separately addressable HSSs.

This reference point is used to exchange signalling between GGSN and BM-SC. This represents the network side boundary of the MBMS Bearer Service from a control plane perspective. This includes user specific Gmb signalling and MBMS bearer service specific signalling. The details for this reference point are described in TS 23.246 and TS 29.061.

This reference point is the roaming variant of the Gmb reference point and is used to exchange signalling between a BM-SC in the VPLMN and a BM-SC in the HPLMN. The details for this reference point are described in TS 23.246 and TS 29.061.

This reference point is used between GGSN and RNS (or BSS Iu mode) for MBMS data delivery using IP multicast. The details for this reference point are described in TS 23.246 and TS 29.281.

This reference point is used to exchange signalling between MBMS GW and BM-SC. This represents the network side boundary of the MBMS Bearer Service from a control plane perspective. This includes MBMS bearer service specific signalling. The details for this reference point are described in TS 23.246 and TS 29.061.

This reference point is used between MBMS GW and BM-SC for MBMS data delivery. The details for this reference point are described in TS 23.246 and TS 29.061.

This reference point is used to exchange signalling between MBMS GW and MME for MBMS Session Control. The details for this reference point are described in TS 23.246 and TS 29.274.

This reference point is used to exchange signalling between MBMS GW and S4-SGSN for MBMS Session Control and for MBMS data delivery in point-to-point mode. The details for this reference point are described in TS 23.246 and TS 29.274.

This reference point is used between MBMS GW and E-UTRAN/UTRAN for MBMS data delivery using IP Multicast. The details for this reference point are described in TS 23.246, TS 29.281 and TS 36.445.

This reference point is used to exchange signalling between MME and MCE for MBMS Session Control. The details for this reference point are described in TS 23.246, TS 36.300 and TS 36.444.

This reference point is used to exchange signalling between MCE and eNodeB for MBMS Session Control. The details for this reference point are described in TS 23.246, TS 36.300 and TS 36.443.

This reference point is used to exchange signalling between Content Provider and BM-SC, either directly or via SCEF and to exchange application data directly between Content Provider and BM-SC. The details for this reference point are described in TS 26.346.

The Rg reference point resides between the GUP Server and the Applications. The Rg reference point allows applications to create, read, modify and delete any user profile data using the harmonized access interface. The GUP Server locates the data repositories responsible of the storage of the requested profile component(s). The details of the Rg reference point are described in TS 23.240.

The Rp reference point resides between the GUP Server and the HSS, and between the Applications and the HSS. The Rp reference point enables the GUP Server and the Applications to access GUP Data Repositories. The HSS is one of the GUP Data Repositories. It stores the IM CN Subsystem user related data. The details of the Rp reference point are described in TS 23.240.
