Session initiation protocol based advanced intelligent network/intelligent network messaging
First Claim
1. A method of enabling distributed transaction oriented telephony functionality for telephony services deployed in a broadband packet network, the method comprising steps of:
- at a first network element comprising a media gateway controller adapted to enable telephony signal traffic through the broadband packet network, encapsulating a functional content of a transaction message in a Protocol Data Unit (PDU) of the broadband packet network;
forwarding the PDU through the broadband packet network to a second network element; and
at the second network element, invoking the functionality using the encapsulated transaction message functional content.

Abstract
A method and system enables distributed transaction oriented telephony functionality for telephony services in a broadband packet network. Exemplary distributed transaction oriented telephony functionality includes Intelligent Network (IN) and Advanced Intelligent Network (AIN) functionality accessed through the legacy Common Channel Signaling (CCS) network using transaction-based messaging protocols, such as Intelligent Network Application Part (INAP) and/or Transaction Capability Application Part (TCAP) protocols. A functional content of a transaction message, such as a TCAP message, is encapsulated in a Protocol Data Unit (PDU) of the broadband packet network. The PDU is forwarded through the broadband packet network to a second network element. The functionality is then invoked using the encapsulated transaction message functional content. In preferred embodiments the PDU is a Session Initiation Protocol (SIP) envelope, into which TCAP message functional content can be mapped.
