Zh (Diameter)


between  BSF  and  HSS

specified from  Rel-6
in  TS 33.220  and  TS 29.109

This reference point allows the BSF to fetch the required authentication information and all GBA user security settings from the HSS.

Commands:

Zn (Diameter)


between  BSF  and  NAF

specified from  Rel-6
in  TS 33.220  and  TS 29.109

This reference point is used by the NAF to fetch the key material agreed during a previous HTTP Digest AKA protocol run over the reference point Ub from the UE to the BSF. It is also used to fetch application-specific user security settings from the BSF, if requested by the NAF.

Commands:
  • BIR/BIA:  Boostrapping-Info-Request/Answer
See also  RFC 6733  for Diameter Base Protocol, and  TS 29.230  for 3GPP-specific Diameter codes and identifiers.

Zpn (Diameter)


between  BSF  and  NAF

specified from  Rel-8
in  TS 33.223  and  TS 29.109

The Zpn reference point is introduced with the GBA Push functionality. It is based on the Zn reference point protocols. The NAF receives the GBA-Push-Info intended for the UE from the BSF over the Zpn reference point and forwards it over Upa.

Commands:
  • GPR/GPI:  GBAPush-Info-Request/Answer
See also  RFC 6733  for Diameter Base Protocol, and  TS 29.230  for 3GPP-specific Diameter codes and identifiers.
