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.
