MARBEN Diameter v7.0 release

This latest release of the Diameter Signaling C++ Stack introduces new 3GPP Release 10 S13, S13', STa, SWa, SWd, SWm, SWx, S6b and H2 interfaces.

This section presents what's new in Marben C++ Diameter release 7.0 with regards to the MARBEN C++ Diameter v6.0 release.

New 3GPP Diameter Interfaces

3GPP SWa

This reference point is defined between the untrusted non-3GPP IP access and the 3GPP AAA Server or Proxy. The SWa reference point is optionally used to authenticate and authorize the UE for the access to the EPS.

3GPP STa

This reference point is defined between a non-3GPP access network and the 3GPP AAA Server or between a non-3GPP access network and the 3GPP AAA Proxy. The STa reference point shall be used to authenticate and authorize the UE, to transport PMIPv6, MIPv4 FA-CoA mode related mobility parameters, to transport DSMIPv6 related mobility parameters or/and to transport charging-related information and optionally information about IP Mobility Mode Selection.

3GPP SWd

This reference point connects the 3GPP AAA Proxy, possibly via intermediate networks, to the 3GPP AAA Server. Its purpose is to transport authentication, authorization and related information in a secure manner.

3GPP SWm

This reference point is defined between the ePDG and the 3GPP AAA Server or between the ePDG and the 3GPP AAA Proxy. The SWm reference point shall be used to authenticate and authorize the UE. The SWm reference point is also used to transport NBM related mobility parameters or DSMIPv6 related mobility parameters in a case the UE attaches to the EPC.

3GPP SWx

This reference point is defined between the 3GPP AAA Server and the HSS. The SWx reference point is used to authorize the UE and to transport NBM related mobility parameters when NBM is used to establish connectivity to the EPC. This reference point is also used to update the HSS with the PDN-GW address information or to retrieve and update other mobility related parameters including static QoS profiles for non-3GPP accesses.

3GPP S6b

This reference point is defined between the 3GPP AAA Server and the PDN-GW. The S6b reference point is used to authenticate and authorize the UE, and update the PDN-GW address to the 3GPP AAA server and HSS, to update the 3GPP AAA server or the 3GPP AAA proxy, to retrieve and update other mobility related parameters including static QoS profiles for non-3GPP accesses. It is also used to authenticate and authorize the incoming MIPv4 Registration Request, to indicate to the PDN GW that a PDN GW reallocation shall be performed or to download subscriber and equipment trace information to the PDN GW.

3GPP H2

This reference point is defined between the 3GPP AAA Server and the HA. It is used to transport authentication, authorization and charging-related information in a secure manner.

3GPP S13

This interface shall enable the ME Identity check procedure between the MME and the EIR.

3GPP S13'

This interface shall enable the ME Identity check procedure between the SGSN and the EIR.
