Methods and systems for providing converged network management functionality in a gateway routing node
First Claim
1. A method for use at a gateway node in a converged telephony/data network for distributing operating status information associated with a node in a signaling system 7 (SS7) network of the converged network to nodes in a data network of the converged network, the method comprising:
- (a) receiving an SS7 network management message including operating status information associated with an SS7 node;
(b) performing a routing key database lookup using information contained in the SS7 network management message and identifying a node in the data network capable of communicating with the SS7 node; and
(c) communicating the operating status information to the identified node in the data network.

Abstract
Disclosed is a communications network element that is capable of routing signaling messages and also performing inter-network management functions in a converged telephony-data network environment. A signaling gateway routing node is adapted to facilitate signaling communication between nodes in a signaling system 7 network and nodes in an Internet protocol (IP) type network. In addition to basic message routing functionality, the signaling gateway routing node is adapted to notify nodes in the IP network when a node in the SS7 network becomes congested or unavailable. In certain cases, the signaling gateway selectively notifies only IP nodes that are concerned with the status of the troubled SS7 node, while in other cases, notification messages are broadcast to all relevant IP nodes. The signaling gateway also serves to filter redundant congestion status queries or polling type messages that are conveyed from IP nodes through to the distressed SS7 node.

20. A signaling gateway comprising:
-
(a) a routing key table for storing routing key information for identifying IP nodes in an IP network that are configured to communicate with an SS7 node in an SS7 network;
(b) a status manager process for determining or receiving status information relating to the SS7 node; and
(c) a communications module operatively associated with the routing key table and the status manager process for communicating the status information to IP nodes configured to communicate with the SS7 node using the routing key information.
