A.2 MC Service User Database behaviour

29.2833GPPDiameter data management applicationsRelease 17TS

The MC Service User Database requests traffic reduction from the MC Service Server when the MC Service User Database is in an overload situation, including OC-OLR AVP in answer commands as described in IETF RFC 7683 [11].

The MC Service User Database identifies that it is in an overload situation by implementation specific means. For example, the MC Service User Database may take into account the traffic over the MC Service Server to MC Service User Database interfaces (e.g. MCPTT-2) or other interfaces, the level of usage of internal resources (CPU, memory), the access to external resources, etc.

The MC Service User Database determines the specific contents of OC-OLR AVP in overload reports and the MC Service User Database decides when to send OC-OLR AVPs by implementation specific means.
