Method and system for providing intelligent network control services in IP telephony
First Claim
1. A telephony system including a first network and a second network, the system comprising:
- a first network call control system configured to provide intelligent network control services to the first network, the first network call control system also being configured to store intelligent network control data corresponding to the intelligent network control services, the first network call control system comprising a legacy telephony service control system;
a second network call control system configured to provide control services to the second network, the second network call control system emulating a first network system such that communications between the legacy telephony service control system and the second network call control system are transparent to the legacy telephony service control system; and
a secure channel coupling the first network call control system to the second network call control system, the secure channel being configured to securely transmit intelligent network control data from the first network call control system to the second network call control system, the second network call control system providing the intelligent network control services to the second network.

Abstract
The present invention is directed to a telephony system that includes a first network and a second network. The system includes a first network call control system configured to provide intelligent network control services to the first network. The first network call control system is also configured to store intelligent network control data corresponding to the intelligent network control services. A second network call control system is configured to provide control services to the second network. A secure channel couples the first network call control system to the second network call control system. The secure channel is configured to securely transmit intelligent network control data from the first network call control system to the second network call control system. As a result, the second network call control system provides the intelligent network control services to the second network.

40. A method for providing a second network with intelligent network service control data stored in a first network service control system, the method comprising:
-
receiving an IP telephony session initiation request at a second network IP proxy server; determining if intelligent network service information is necessary to initiate the session; transmitting the IP telephony session initiation request from the second network IP proxy server to a second network location manager if it is determined that intelligent network service information is necessary to initiate the session; and creating a secure channel between the second network location manager and the first network service control system, the secure channel being configured to securely transfer the intelligent network service control data from the first network service control system to the second network location manager. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)
