Abstract
A telecommunications system wherein the dialing of a directory number which has been forwarded triggers an intelligent network signal which is directed to the Internet. The signal is transmitted through the Internet to a database in the Internet. The database returns call set up directions which are used by the originating switching system to establish a voice link from the calling station to the station having the forwarded number. The intelligent network signal may be transmitted from the terminating switching system to a signal transfer point (STP) and to the Internet. Within the Internet the signal is directed to an Internet database where a forwarding number for the forwarded number is obtained. This is transmitted back to the signal switching point, which then uses the forwarding number to complete the connection. In another embodiment, where a number has been forwarded to a station that is connected only to the Internet, the Internet database may provide a domain name address. This address is then used to establish a link through the Internet between the calling and called station. In this instance the Internet handles both the signaling and the voice connections.

14. A method for using a telecommunications network comprising a Local Exchange Carrier (LEC) having trunked together switching systems for selectively establishing a connection between a first telephone station connected to a first of said switching systems and a second telephone station connected to a second of said switching systems, comprising the steps of:
-
a) storing in a database, external to said telecommunications network and connected to the Internet, a table of information for call routing through said telecommunications network, said table comprising entries relating to subscribers to said telecommunications network; b) setting in at least one of said first and second switching systems a trigger for initiating call set-up signaling in said telecommunications network; c) receiving from said first telephone station a telephone number for said called station; d) responsive to receipt of said telephone number delivering a signal corresponding to said telephone number to the switching system wherein said trigger has been set in step b); e) responsive to delivery of said signal in step d), formulating a first data message in a Common Channel Interoffice Signaling (CCIS) format; f) transmitting said first data message to an interface connected between said telecommunications network and said Internet; g) responsive to receipt of said first data message by said interface, formulating a second data message in Transmission Control Protocol/Internet Program (TCP/IP) format containing said telephone number; h) transmitting said second data message to said database; i) returning from said database to said interface a response message in Transmission Control Protocol/Internet Program (TCP/IP) format including routing information derived from said database for routing a call to said second station; j) responsive to receipt of said response message by said interface, formulating a third data message in said Common Channel Interoffice Signaling (CCIS) format including said routing information; k) transmitting said third data message from said interface to said telecommunications network; and l) responsive to receipt of said third data messages, routing said call in accordance with said third data message. - View Dependent Claims (15, 16)

17. A communications system comprising in combination:
-
a) a first switched telecommunications network having trunked together switching systems connected by local links to subscriber stations and having a switching control data network using a first data protocol for effecting selective connection of said subscriber stations through said switching system; b) public a wide area data network, separate from said first switched telecommunications network, using a second data protocol to link multiple local area networks using therein data protocols different than said second data protocol, said public wide area data network being linked to said first telecommunications network through an interface between said networks, said interface being capable of performing protocol translation; c) a wide area data network routing database connected to said public wide area data network and having stored therein routing information for effecting selective connection of said subscriber stations through said switching systems in said first switched telecommunications network pursuant to preselected options of said subscriber stations stored in said database; d) said first switched telecommunications network having control parameters set therein whereby the initiation of a connection between a caller at one of said subscriber stations to a called station having a preselected option for routing stored in said database results in data signaling through said interface to and from said database resulting in (i) retrieval of routing instructions from said stored preselected option, and (ii) effecting of said initiated connection pursuant to said routing instructions. - View Dependent Claims (18, 19, 20, 21, 22)
