System for providing enhanced subscriber services using ISUP call-setup protocol
First Claim
1. A method of retrieving and delivering services to subscribers of a telecommunications network having at least one local switch and an advanced intelligent network comprising at least one service switch point/tandem and at least one database of subscriber services, said method comprising the steps of:
- sending messages over said advanced intelligent network utilizing the Signaling System 7 signaling protocol;
formatting messages for retrieval of subscriber services from said database utilizing a Transaction Capabilities Application Part/Advanced Intelligent Network protocol translator;
formatting messages for retrieval of subscriber services from said database utilizing an Integrated Services Digital Network User Part protocol translator;
determining whether or not said local switch is capable of utilizing said Signaling System 7 signaling protocol;
routing messages from said local switch to said service switch point/tandem if said local switch is not capable of utilizing said Signaling .System 7 signaling protocol;
determining whether or not said local switch is capable of communicating with said Transaction Capabilities Application Part/Advanced Intelligent Network protocol translator, if said local switch is capable of utilizing said Signaling System 7 signaling protocol;
sending messages back and forth from said local switch to said database of subscriber services if said local switch is capable of utilizing said Signaling System 7 signaling protocol and capable of communicating with said Transaction Capabilities Application Part/Advanced Intelligent Network protocol translator;
determining whether or not said local switch is capable of utilizing the Integrated Services Digital Network User Part call-setup protocol, if said local switch is capable of utilizing said Signaling System 7 signaling protocol, but is not capable of communicating with said Transaction Capabilities Application Part/Advanced Intelligent Network protocol translator;
routing messages from said local switch to said service switch point/tandem if said local switch is capable of utilizing said Signaling System 7 signaling protocol, but is not capable of communicating with said Transaction capabilities Application Part/Advanced Intelligent Network protocol translator and is not capable of utilizing said Integrated Services Digital Network User Part call-setup protocol; and
sending messages back and forth from said local switch to said database of subscriber services, utilizing said Integrated Services Digital Network User Part call-setup protocol, if said local switch is capable of utilizing said Signaling System 7 signaling protocol and said Integrated Services Digital Network User Part call-setup protocol, but is not capable of communicating with said Transaction Capabilities Application Part/Advanced Intelligent Network protocol translator.

Abstract
A system and method for retrieving enhanced subscriber services from at least one database and delivering those services to the subscribers of a telecommunications network without requiring the expensive upgrading of local switches (LSs) to operate with the Transaction Capabilities Application Part/Advanced Intelligent Network (TCAP/AIN) communications protocol. The system comprises a plurality of LSs which are connected to an Advanced Intelligent Network (AIN) and provide the subscribers with access to the network. The system also includes at least one virtual service switching point (ViSSP) within the AIN for storing the database of enhanced subscriber services. LSs or tandem switches may retrieve enhanced subscriber services from the ViSSP utilizing the Integrated Services Digital Network User Part (ISUP) call-setup protocol.
