Abstract:
1. A method for use in a communication network for enabling a signaling node to automatically update routing instructions that are maintained at a network routing node, the method comprising: (a) at a signaling node in an Internet protocol network, generating a routing key registration message, the routing key registration message including SS7 routing key data for updating the status of routing key information associated with the signaling node, the SS7 routing key data including at least one of an originating point code (OPC), a destination point code (DPC), a service indicator (SI), a subsystem number (SSN), and a circuit identification code (CIC); (b) sending the routing key registration message to a network routing node capable of routing messages between the IP network and an SS7 network; and (c) at the network routing node, receiving the routing key registration message and using the SS7 routing key data in the routing key registration message to dynamically update a routing key database entry associated with a connection between the signaling node and the network routing node, wherein using the SS7 routing key data includes extracting the at least one of an OPC, a DPC, an SI, an SSN, and CIC from the routing key registration message and using the at least one of an OPC, a DPC, an SI, an SSN, and a CIC extracted from the routing key registration message to update corresponding fields in the routing key database entry.
