Computer telephony integration gateway
First Claim
1. A telecommunications system comprising:
- a public telecommunications intelligent network (IN) including an IN service control element and an IN switching control element providing IN services following IN control and event notification procedures;
a private telecommunications network including a computer telephony integration (CTI) server providing CTI services to the public telecommunications IN following CTI control and event notification procedures; and
a network control gateway coupled to the public and private networks establishing a service logic control path between the CTI server and the IN service control element to permit the CTI server to request a service from the IN service control element.

Abstract
A telecommunications system combines the benefits provided by a public intelligent network and a customer premise equipment (CPE)-based private network to provide enhanced telecommunications services. The public intelligent network includes an IN service control element and an IN switching control element used to provide IN services following IN control procedures. The private telecommunications network includes a computer telephony integration (CTI) server providing CTI services following CTI control procedures. A network gateway is provided between the public and private networks. The network gateway establishes a service logic communication between the IN service control element and the CTI server and permits, for example, the CTI server to request a service is from the IN service control element. Events related to the requested service are returned via the network gateway. The network gateway includes a CTI interface that emulates a private branch exchange switch to receive and translate switching service communications from the CTI server, and an IN interface that emulates a public IN node to receive and translate service communications from the service control point.

14. A telecommunications system comprising:
-
a public telecommunications intelligent network (IN) including an IN service control element and an IN switching control element providing IN services following IN control procedures; a private telecommunications network including a computer telephony integration (CTI) server providing CTI services following CTI control procedures and a first group of plural telephones connected to the public IN network; and a network gateway coupled to the public and private networks through which the CTI server requests a service from the IN service control element, wherein a virtual private network connecting the first group of telephones using the public telecommunications intelligent network is established in accordance with communications between the service control element and the CTI server through the network gateway. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method of enhancing telecommunications services offered in a private network domain controlled by a private network computer server with services from a public intelligent network (IN) that includes an IN service control element and an IN switching element, comprising the steps of:
-
providing a network control gateway between the computer server and the IN service control clement; establishing a service logic control path between the computer server and the IN service control element via the network control gateway; the computer server requesting from the gateway over the service logic control path a public IN switching service for the private network; the gateway conveying a switching message corresponding the requested switching service to the service control element; and in response to the switching message, the service control element performing the requested switching function using the switching element. - View Dependent Claims (21, 22)

23. A method of enhancing telecommunications services offered in a private network controlled by a computer telephony integrated (CTI) server with services obtained from an intelligent network (IN) that includes a service control element and a switching element, comprising the steps of:
-
establishing service logic relating to a private network service in the IN service control element and one or more triggering conditions in the IN switching element; providing a gateway coupled to the CTI server and IN service control element; detecting in the IN switching element a call having a trigger condition; invoking the private network service logic in the IN service control element and communicating information regarding the call to the CTI server; processing the call information in the CTI server; instructing the IN service control element to complete the call; the IN service control element instructing the IN service switching element to complete the call; and the IN service switching element completing the call. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)
