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.
