The support of the Diameter message priority mechanism by PCC functional elements is optional. PCC functional elements that support Diameter message priority mechanism shall comply with the procedures specified in this annex.

IETF RFC 7944 [40] specifies the Diameter message priority mechanism that allows Diameter nodes to indicate the relative priority of Diameter messages. With this information, other Diameter nodes can leverage the relative priority of Diameter messages into routing, resource allocation, set the DSCP marking for transport of the associated Diameter message, and also abatement decisions when overload control is applied. This includes the definition of Diameter message priority related AVPs and the Diameter message priority related behaviour.
