Claim:
1. A system for performing Diameter overload control, the system comprising: a Diameter server configured to, prior to detecting an overload condition, assign Diameter sessions to overload groups and to communicate the assignments to a Diameter routing node using Diameter messages containing Diameter overload control information, wherein the Diameter overload control information indicates that a first plurality of Diameter sessions are assigned to a first overload group and that a second plurality of Diameter sessions are assigned to a second overload group; and the Diameter routing node including: at least one network interface for receiving a second Diameter message related to one of the plurality of Diameter sessions, and a Diameter overload control unit configured to detect an overload condition associated with the second Diameter message and to communicate an indication of the overload condition to a plurality of Diameter nodes that originate the first plurality of Diameter sessions assigned to the first overload group using at least a third Diameter message defined for a purpose other than overload control.
