OriginHost and OriginRealm are optional parameters that define values for Diameter attributes Origin-Host and Origin-Realm in SWm, S6b and SWx application messages Radiator 3GPP AAA Server sends. These parameters are typically used when multiple parallel Radiator 3GPP AAA workers with the same Diameter identity used in conjunction with Radiator Service Provider Module hashbalance support.

These parameters are not set by default and Origin-Host and Origin-Realm attributes get their values from the DiaPeerDef clause use for forwarding the message. Special formatting characters are supported. Formatting is done when the configuration is loaded and AuthBy Dia3GPPAAAServer clause is activated.

See goodies file 3gpp-aaa-server-hashbalance.cfg for a sample configuration.

# We use local Diameter identity for peering with relay and
# this global identity for 3GPP AAA Server messages.
