Section: 17.8.3 Transient Failures
Content: Errors that fall within the transient failures category are used to inform a peer that a request could not be satisfied at the time it was received, but it may be satisfied in the future. The Result-Code AVP values defined in Diameter Base IETF RFC 6733 [111] are applicable. Also the following specific Gmb Experimental-Result-Code value is defined for transient failures: DIAMETER_ERROR_OUT_OF_RESOURCES (4121) This error covers the case when a MBMS Session Start procedure could not be performed due to a temporary resource shortage in the GGSN. The BM-SC may re-try later.
