Methods, systems, and computer readable media for answer-based routing of diameter request messages

A system for answer-based routing of Diameter request messages, the system comprising:

• a Diameter signaling router (DSR) including:
• a Diameter message processor for receiving a first Diameter request message from a first Diameter node;
• a message cache for caching a copy of at least a portion of the first Diameter request message;
• and
• an answer message-based request routing module for:
• routing the first Diameter request message to a second Diameter node;
• determining whether a predetermined condition associated with an answer to the first Diameter request message exists;
• and
• in response to determining that the predetermined condition exists:
• retrieving the cached portion of the first Diameter request message;
• generating a second Diameter request message that includes the cached portion of the second Diameter request message;
• and
• routing the generated Diameter request message.

A non-transitory computer readable medium comprising computer executable instructions embodied in a non-transitory computer readable medium and when executed by a processor of a computer performs steps comprising:

• at a Diameter signaling router (DSR)
• receiving a first Diameter request message from a first Diameter node;
• caching, at the DSR, a copy of at least a portion of the first Diameter request message;
• routing the Diameter request message to a second Diameter node;
• determining whether a predetermined condition associated with an answer to the first Diameter request message exists;
• and
• in response to determining that the predetermined condition exists:
• retrieving the cached portion of the first Diameter request message;
• and
• generating a second Diameter request message that includes the cached portion of the first Diameter request message;
• and
• routing the generated second Diameter request message.
