F.2 S6a/S6d interfaces

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

F.2.1 General

Diameter load control mechanism is an optional feature.

It is recommended to make use of IETF RFC 8583 [60] on the S6a/S6d interfaces where, when applied, the MME or the SGSN shall behave as receiving nodes and the HSS as a reporting node.

F.2.2 HSS behaviour

The HSS may report its current load by including a Load AVP of type HOST in answer commands as described in IETF RFC 8583 [60].

The HSS calculates its current load by implementation specific means. For example, the HSS may take into account the traffic over the S6a/d interfaces or other interfaces, the level of usage of internal resources (CPU, memory), the access to external resources, etc.

The HSS determines when to send Load AVPs of type HOST by implementation specific means.

F.2.3 MME/SGSN behaviour

When performing next hop Diameter Agent selection for requests that are routed based on realm, the MME/SGSN may take into account load values from Load AVPs of type PEER received from candidate next hop Diameter nodes, as per IETF RFC 8583 [60].
