1. A method for providing answer message-based network management, the method comprising:
- receiving, at a Diameter signaling router (DSR), a first Diameter answer message from a first Diameter node, wherein the first Diameter answer message includes error indicator information;
examining, at the DSR, the error indicator information included in the first Diameter answer message; and
using the error indicator information to update status information for routes maintained by the DSR to the first Diameter node.

Abstract
Methods, systems, and computer readable media for performing Diameter answer message-based network management at a Diameter signaling router (DSR) are disclosed. According to one method, a Diameter answer message that includes error indicator information is received from a first Diameter node at a DSR. The error indicator information included in the Diameter answer message is examined, at the DSR, and information based on the error indicator information is used to update status information for routes maintained by the DSR to the first Diameter node.

11. A method for unsolicited network management information communication, the method comprising:
-
establishing, by a Diameter signaling router (DSR), a lost answer message timer signifying a time period, after which, if an answer message responsive to a Diameter request message has not been received, it is determined that the answer message is lost; updating Diameter network management information associated with the Diameter request message in response to determining that no Diameter answer message related to the Diameter request message was detected prior to the expiration of the lost answer message timer; and communicating the Diameter network management information associated with the Diameter request message to one or more Diameter nodes in the network. - View Dependent Claims (12, 13, 14, 15, 16, 17)
