A.3 MC Service Server and Configuration Management Server behaviour

29.2833GPPDiameter data management applicationsRelease 17TS

The MC Service Server and the Configuration Management Server apply required traffic reduction received in answer commands to subsequent applicable requests, as per IETF RFC 7683 [11].

The MC Service Server and the Configuration Management Server achieve requested traffic reduction by implementation specific means. For example, the MC Service Server or the Configuration Management Server may implement message throttling with prioritization or a message retaining mechanism for operations that can be postponed.

Diameter requests related to priority traffic (e.g., MCPTT emergency call), detected via the presence of priority information (e.g., Resource-Priority header field for MPS) in SIP messages as described in 3GPP TS 24.229 [13], have the highest priority. Depending on regional/national requirements and network operator policy, these Diameter requests shall be the last to be throttled, when the MC Service Server has to apply traffic reduction.
