Claim Text:
1. A method for Destination-Host defined overload scope, the method comprising: at a Diameter agent for routing Diameter signaling messages within a telecommunications network: receiving, by the Diameter agent and from a Diameter client, a Diameter session establishment request message for establishing a Diameter session with a Diameter server; in response to receiving the Diameter session establishment request message, creating an overload group; generating, by the Diameter agent, an alias; assigning, by the Diameter agent, the alias to the overload group; routing, by the Diameter agent, the Diameter session establishment request message to the Diameter server; receiving, by the Diameter agent and from the Diameter server, a Diameter response message to the Diameter session establishment request message; and remapping an origin host parameter value in the Diameter response message by replacing, in the Diameter response message, an address of the Diameter server with the alias for the overload group; and routing, by the Diameter agent and to the Diameter client, the Diameter response message with the origin host parameter value set to the alias for the overload group, thereby causing the Diameter client to address subsequent messages associated with the session to the alias.
