Subscriber Session and Binding Database Management

The Policy DRA will invoke the SBRs to perform relevant database operations after or in parallel with sending the Answer messages out. Which database operations to be performed depends on the Diameter interface type in the incoming Diameter Request, the Diameter Request message type (session initiation, session update, or session termination), and the results from the responses. Various operations can be performed:

• Finding, creating, or updating binding records
• Removing Suspect Binding records
• Creating or removing alternate key binding records
• Finding, creating, refreshing, or removing session records
