Intelligent network and method for providing voice telephony over ATM and closed user groups
First Claim
1. An intelligent network for use with an ATM network to set up an ATM switched virtual circuit to provide voice telephony over ATM services and closed user group services, the intelligent network comprising:
- a multi-service control point operable to receive an input extracted from an input ATM setup message that includes a called party phone number value and a voice telephony over ATM designator, execute a closed user group service to determine whether to authorize a voice telephony over ATM call between a calling party and a called party, and generate an output in response for use in generating an output ATM setup message;
an ATM signaling intercept processor operable to intercept the input ATM setup message from an ingress ATM edge switch of the ATM network, extract the input from the input ATM setup message, communicate the input to the multi-service control point, receive the output generated by the multi-service control point, generate the output ATM setup message using the output, and communicate the output ATM setup message to the ingress ATM edge switch of the ATM network; and
a service administration operable to provision the multi-service control point and the ATM signaling intercept processor.

Abstract
An illustrative intelligent network and method for providing voice telephony over ATM and closed user groups are provided that can provide significant advantages. A method for providing a closed user group service to authorize VToA calls includes determining the closed user group identifiers for a calling party, determining the closed user group identifiers for a called party, locating a common closed user group identifier that is common to the calling party and the called party, analyzing the privileges of the calling party in the common closed user group to determine if the calling party can make calls to other users of the common closed user group, and analyzing the privileges of the called party in the common closed user group to determine if the called party can receive calls from other users of the common closed user group. An illustrative intelligent network and data structure to provide closed user group services is also provided.

9. A method for providing voice telephony over ATM and closed user group services using an intelligent network and a switched virtual circuit over an ATM network, the method comprising:
-
intercepting an input ATM setup message from an ingress ATM edge switch of the ATM network; extracting information from the input ATM setup message; analyzing the information to determine if the input ATM setup message is a request to set up a switched virtual circuit for voice telephony over ATM; executing a closed user group service to determine whether to authorize a VToA call between a calling party and a called party; determining an ATM address of customer premises equipment of the called party; generating an output ATM setup message that includes the ATM address of the customer premises equipment of the called party; and communicating the output ATM setup message to the ingress ATM edge switch of the ATM network. - View Dependent Claims (10, 11)

12. A method for providing a closed user group service to authorize voice telephony over ATM calls using an intelligent network and a switched virtual circuit over an ATM network, the method comprising:
-
intercepting an input ATM setup message from an ingress ATM edge switch of the ATM network extracting information from the input ATM setup message; determining closed user group identifiers for a calling party; determining closed user group identifiers for a called party; locating a common closed user group identifier that is common to the calling party and the called party; analyzing privileges of the calling party in the common closed user group to determine if the calling party can make calls to other users of the common closed user group; analyzing privileges of the called party in the common closed user group to determine if the called party can receive calls from other users of the common closed user group, and wherein a voice telephony over ATM call between the calling party and the called party is completed if a common closed user group identifier is located, the calling party has privileges to call other users of the common closed user group, and the called party has privileges to receive calls from other users of the common closed user group; generating an output ATM setup message that includes an ATM address of customer premises equipment of the called party when the voice telephony over ATM call between the calling party and the called party is to be completed; and communicating the output ATM setup message to the ingress ATM edge switch of the ATM network. - View Dependent Claims (13, 14, 15, 16, 17, 18)
