Method and apparatus for messaging between disparate networks

A computer program product for messaging between disparate networks, the computer program product including a media with a computer program embodied thereon, the computer program comprising:

• computer program code for receiving a signaling information message from a first network;
• computer program code for storing first network specific information from the signaling information message in an interaction database;
• computer program code for determining second network specific information corresponding to the first network specific information and storing the second network specific information in the interaction database;
• computer program code for sending the signaling information message to a second network using the second network specific information;
• computer program code for receiving a response from the second network;
• computer program code for associating the response with the signaling information message by referencing the interaction database;
• and
• computer program code for sending the response to the first network using the first network specific information.

Apparatus for messaging between disparate networks comprising:

• means for receiving a signaling information message from a first network;
• means for storing first network specific information from the signaling information message in an interaction database;
• means for determining second network specific information corresponding to the first network specific information and storing the second network specific information in the interaction database;
• means for sending the signaling information message to a second network using the second network specific information;
• means for receiving a response from the second network;
• means for associating the response with the signaling information message by referencing the interaction database;
• and
• means for sending the response to the first network using the first network specific information.

A service control gateway that enables messages related to telecommunication services to be processed across disparate networks by performing the steps of:

• receiving a signaling information message from a first network;
• storing first network specific information from the signaling information message in an interaction database;
• determining second network specific information corresponding to the first network specific information and storing the second network specific information in the interaction database;
• sending the signaling information message to a second network using the second network specific information;
• receiving a response from the second network;
• associating the response with the signaling information message by referencing the interaction database;
• and
• sending the response to the first network using the first network specific information.

A service control gateway that enables telecommunication services to be provided across disparate networks, the service control gateway comprising:

• connections for a first network and a second network;
• one or more processors for controlling the operation of the service access gateway;
• and
• a computer readable memory system connected to the one or more processors, the computer readable memory system operable to maintain an interaction database for storing first network specific information derived form a signaling information message sent by the first network, and second network specific information corresponding to the signaling information message, wherein the first network specific information and the second network specific information are accessible by the one or more processors under the control of a computer program so that the signaling information message can be transferred between the first network and the second network.
