between  HLR  and  AuC

[R96]+

When an HLR receives a request for authentication and ciphering data for a Mobile Subscriber and it does not hold the requested data, it requests it from the AuC via the H-interface, stores it and delivers it to the VLR and SGSN and MME which need them to perform the security functions for a mobile station.

The protocol used to transfer the data over this interface is not standardized.

between  UE  and  HA

[R8]+

This is the reference point for signalling and user data transfer between UE and HA. H1 may be transported over IP connectivity provided by I-WLAN or 3GPP access system. The H1 should be a subset of S2c.

Source:   TS 23.327, clause 5.5

between  HA  and  3GPP AAA Server / Proxy

[R8]+

This reference point defines the interface between HA and 3GPP AAA infrastructure (3GPP AAA server or 3GPP AAA proxy) and is used to transport authentication, authorization and charging-related information in a secure manner.

The H2 should be a subset of S6b.

between  AR (Access Router)  and  HA

[R8]+

This is the IP transport reference point to carry the end-to-end UE-HA signalling and user data between Access Router and HA. Since there is no direct signalling messages between these two entities this is simple IP transport reference point, which does not require additional specification.

Source:   TS 23.327, clause 5.5

between  HA  and  PDN (Packet Data Network)

[R8]+

This reference point defines the interface from the HA to external PDN.

The HGi should be a subset of SGi.

Source:   TS 23.327, clause 5.5

Up       Top


between  HA  and  VLR

[R11]+

This reference point is used to transfer to the VLR the CSG subscription information stored in the VPLMN for roaming UEs.

Signalling on this interface uses the Mobile Application Part (MAP), which in turn uses the services of Transaction Capabilities (TCAP) (see TS 29.002).
