29.2723GPPEvolved Packet System (EPS)Mobility Management Entity (MME) and Serving GPRS Support Node (SGSN) related interfaces based on Diameter protocolRelease 17TS

IETF RFC 7683 [50] specifies a Diameter overload control mechanism which includes the definition and the transfer of related AVPs between Diameter nodes.

Depending on regional/national requirements and network operator policy, priority traffic (e.g. MPS as described in 3GPP TS 22.153 [52]) shall be exempted from throttling due to Diameter overload control up to the point where requested traffic reduction cannot be achieved without throttling the priority traffic.
