Sc Interface Response Codes

The Oracle Communications Core Session Manager and SLRM function insert a set of base protocol response codes to the Result-Code AVP of Response messages to indicate what has transpired based on the request. The sole Sc interface response code indicating success is DIAMETER_SUCCESS 2001.

  • SC_DIAMETER_SUCCESS 2001
  • SC_DIAMETER_FIRST_ASSOC 2002
  • SC_DIAMETER_SUBSEQ_ASSOC 2003
  • SC_DIAMETER_FIRST_REG 2004
  • SC_DIAMETER_SUBSEQ_reg 2005

There are multiple response codes used to indicate failure, including:

  • SC_DIAMETER_ERROR_CORE_NOT_FOUND 5001
  • SC_DIAMETER_ERROR_PEER_NOT_FOUND 5002
  • SC_DIAMETER_ERROR_PROTO_VER_MISMATCH 5003
  • SC_DIAMETER_ERROR_DATABASE 5004
  • SC_DIAMETER_ERROR_TIMEOUT 5005
  • SC_DIAMETER_ERROR_UNABLE_COMPLY 5012

The format of each response message includes the response code AVP indicating one of the results above. Message format is provided in the Sc Interface Appendix. See RFC 6733 for detailed, generic information about Diameter response-code AVPs.
