Methods, systems, and computer readable media for destination-host defined overload scope

摘要

Methods, systems, and computer readable media for Destination-Host defined overload scope are disclosed. According to one aspect, a method for Destination-Host defined overload scope includes, at an entity for processing Diameter signaling messages: identifying at least one Diameter session as a member of an overload group; specifying an alias for use to identify the entity for processing Diameter signaling messages as a destination of Diameter messages; associating the specified alias with the overload group; and including the specified alias in messages associated with members of the overload group.

主权项

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.
