Message restriction for diameter servers

摘要

Communication networks and methods are disclosed for providing a message restriction process used to control the transmission of Diameter messages. The communication network includes a Diameter server operable to serve a plurality of Diameter clients. The Diameter server detects a triggering event for initiating the message restriction process, such as detecting an overload condition. The Diameter server then generates control information that defines the Diameter messages that the Diameter clients are authorized to transmit during the message restriction process. The Diameter server generates a message restriction instruction that includes the control information, and transmits the message restriction instruction to one or more of the Diameter clients to initiate the message restriction process based on the control information.

1. A system comprising:
a Diameter server configured to serve a plurality of Diameter clients; the Diameter server detects a triggering event for initiating a message restriction process, generates control information responsive to detection of the triggering event defining that a Diameter client is authorized to transmit Diameter STOP messages to the Diameter server during the message restriction process and is not authorized to transmit Diameter START messages to the Diameter server during the message restriction process, generates a message restriction instruction that includes the control information, and transmits the message restriction instruction to the Diameter client to initiate the message restriction process based on the control information.
