Capabilities Exchange Messages

The capabilities exchange message sequence, CER/CEA, is standard Diameter messaging used as a means of correlating client capabilities with server services. The CER message is used to discover peer's identity and exchange capabilities, including applications supported, vendor-Id and device addressing information. Key AVPs that must match include:

  • Vendor-Id = 9148 (Oracle-Acme-Id)
  • Vendor-Specific-Application-ID = 9999 (Oracle-Acme-Sc)

The Oracle Communications Core Session Manager proceeds with presenting its cluster membership and registering its cores upon a successful CEA response.
