Systems and methods for routing a message through a signaling network associated with a public switched telephone network (pstn), including a method for performing global title routing on an internet protocol (ip) address

Abstract

A datagram is received from a packet-switched network at a first network node; the first network node may be a node of the packet-switched network or a node of a signaling network associated with a Public Switched Telephone Network (PSTN). The datagram includes a destination address of a destination node of the signaling network; the destination address has an address format associated with the packet-switched network, such as that defined by the Internet Protocol. A message is constructed for transmission from the first network node to a node of the signaling network; the message includes an address field containing the destination address and a translation type field containing an indicator that the destination address has an address format associated with the packet-switched network. The message is transmitted to a signaling network node, at which the translation type field of the message is examined and, if the indicator in the translation type field corresponds to the address format associated with the packet-switched network, the destination address is translated to a translated destination address corresponding to the destination node of the signaling network; the translated destination address has an address format defined by the signaling network protocol. The signaling network node may be the destination node. The systems and methods can be used to perform global title routing in the signaling network associated with the PSTN based on an Internet Protocol (IP) address associated with the packet-switched network.
