Sc Interface Messages

The Sc Interface uses four message types to perform the SLRM function, including:

  • Capabilities Exchange
  • Device Watchdog
  • Service Association
  • Core Registration

Each message type uses a pre-defined request/answer sequence using timing that is dynamically managed and impacts the client-server as well as the load balance operational state between the SLRM and the Oracle Communications Core Session Manager. Each sequence includes a response code in the answer message indicating if the request was a success or failure.

The high-level format, which shows message AVPs, for each of these messages is provided in the Sc Interface Appendix within this document. See RFC 6733 for detailed, generic information about Diameter message packet format and handling.
