1. A method of modifying a signaling protocol stack to transmit a Signaling System 7 (SS7) telecommunication signaling message over a data network from an origination node to a destination node, said signaling protocol stack having a Signaling Connection Control Part (SCCP) protocol layer on top of a Message Transfer Protocol (MTP) protocol layer, said method comprising the steps of:

  • replacing the MTP protocol layer with an Internet Protocol (IP) protocol layer;

    adding a SCCP-IP mapping function between the SCCP protocol layer and the IP protocol layer;

    mapping the SS7 signaling message from the SCCP protocol layer in the origination node into an IP message utilizing the SCCP-IP mapping function; and

    sending the IP message over the data network from the origination node to the destination node.
