SESSION INITIATION PROTOCOL BASED ADVANCED INTELLIGENT NETWORK/INTELLIGENT NETWORK MESSAGING

摘要

A method and system enables distributed transaction oriented telephony functionality for telephony services in a broadband packet network. Exemplar y distributed transaction oriented telephony functionality includes Intelligen t 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 (INA P) and/or Transaction Capability Application Part (TCAP) protocols. A functiona l 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 forward ed 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.
