First Claim
1. A method for managing the flow of signaling traffic entering a signaling system 7 (SS7) network, the method comprising:
- at a signaling device within the SS7 network, the SS7 network having a plurality of signaling gateways for connecting the SS7 network to a non-SS7 network;
storing route management proxy information associating a range of subscriber directory numbers with a preferred signaling gateway and an alternate signaling gateway, different from the preferred signaling gateway, for accessing the SS7 network;
detecting a network management event, wherein the network management event is a change in status of a signaling link in the SS7 network, and, in response;
generating a route management proxy message, the message including information associating the range of directory numbers with the alternate signaling gateway; and
sending the message to a breakout gateway control function device in the non-SS7 network, the breakout gateway control function directing signaling traffic from the non-SS7 network to the SS7 network, the message for directing the breakout gateway control function device to change its entry point for signaling traffic associated with the range of directory numbers into the SS7 network from the preferred signaling gateway to the alternate signaling gateway.

Abstract
Methods, systems, and computer readable media for managing the flow of signaling traffic entering a signaling system 7 (SS7) based network having a plurality of gateways for connecting the SS7 network to a non-SS7 network are disclosed. According to one aspect, a method for managing the flow of signaling traffic entering the SS7 based network includes generating, at a signaling node within the SS7 network, a route management message including information for identifying one of the plurality of gateways as the preferred gateway for traffic into the SS7 network. The message is sent to a node in the non-SS7 network for directing traffic into the SS7 network via the identified gateway.
