Abstract
A mapping function and method for mapping a Signaling System 7 (SS7) telecommunication signaling message from a Signaling Connection Control Part (SCCP) protocol layer to an Internet Protocol (IP) protocol layer in order to transmit the SS7 signaling message over a data network from an origination node to a destination node. The mapping function receives the SS7 signaling message from the SCCP protocol layer by sending and receiving Message Transfer Protocol (MTP) primitives from the mapping function to the SCCP protocol layer. The mapping function then maps the received SS7 signaling message into an IP message by mapping MTP primitives into IP primitives, mapping the SS7 message address into an IP message address, and utilizing a user interface to set IP protocol parameters that cannot be transferred by the SCCP protocol layer. The mapping function then sends the mapped IP message to the IP protocol layer by sending and receiving IP primitives from the mapping function to the IP protocol layer.
