Abstract
A method for Diameter signaling message external identifier address resolution and routing includes receiving a Diameter signaling message, decoding the Diameter signaling message and determining that an external identifier attribute value pair (AVP) is present in the Diameter signaling message. The method further includes decoding contents of the external identifier AVP, performing a lookup in a domain table using a domain identifier component of the external identifier AVP and locating an entry corresponding to the domain identifier component, determining whether a local identifier table is configured for the domain identifier component, performing a lookup in a local identifier table using a local identifier component of the external identifier AVP, populating at least one Diameter routing AVP of the Diameter signaling message with Diameter routing information obtained from the lookup in the domain table or the lookup in the local identifier table, and routing the Diameter signaling message using the Diameter routing information.
