METHOD OF AND SYSTEM FOR PROVIDING QUALITY OF SERVICE IN IP TELEPHONY
First Claim
1. A method comprising:
- initiating, based on a first message, an IP telephony session between a calling party and a called party;
allocating, at a first access control manager and based on the first message, a temporary IP proxy address to the called party, where the first access control manager links, by a first access point, an IP network, associated with the calling party and the called party, to a virtual asynchronous transfer mode (ATM) circuit;
allocating, at a second access control manager, and based on a second message, a temporary IP proxy address to the calling party, where the second access control manager links, by a second access point, the IP network to the virtual ATM circuit;
routing IP media traffic, during the session, between the calling party and the first access control manager;
routing IP media traffic, during the session, between the called party and the second access control manager; and
routing ATM media traffic, which is based on the IP media traffic, between the first access control manager and the second access control manager,where the first access control manager and the second access control manager are at least partially implemented in hardware.

Abstract
A method and system for providing quality of service in an IP telephony session between a calling party and a called party establishes a high quality of service ATM virtual circuit for the session between first and second devices, each of the devices having ATM capability and IP capability. The first and second devices provide bidirectional translation between IP media and ATM media. The system transports IP media for the session between the calling party and the first device, and between said called party and a second device. The virtual circuit transports ATM media for the session between the first and second devices. An intelligent control layer provides IP and ATM signaling to set up the session.

10. A system for providing a quality of service IP telephony session between a calling party and a called party, the system comprising:
-
a first device, having an assigned temporary IP session proxy destination address for the called party, connected between an IP telephony network and a ATM network, the first device providing a bi-directional translation between IP media traffic, routed from the calling party, and ATM traffic, associated with the called party; and a second device, having an assigned temporary IP session proxy destination address for the calling party, connected between the IP telephony network and the ATM network, the second device providing a bi-directional translation between IP media traffic, routed from the called party, and ATM traffic, associated with the calling party. - View Dependent Claims (11, 12, 13, 14)

15. A device-implemented media service control point for enabling quality of service for an internet protocol telephony session, the device-implemented media service control point comprising:
-
a server to assign, via a first session initiated protocol (SIP) message, a temporary IP proxy destination address, for a called party, to a first access control manager, the first access control manager to couple an IP network to an ATM network at a first access point, where the server is further to; assign, via a second session initiated protocol (SIP) message, a temporary IP proxy source address, for a calling party, to a second access control manager, the second d access control manager to couple the IP network to the ATM network at a second access point; route IP media traffic, during the session, between the calling party and the first access control manager; route IP media traffic, during the session, between the called party and the second access control manager; and where the ATM network routes ATM traffic, which is translated from the IP media traffic, between the first access control manager and the second access control manager. - View Dependent Claims (16, 17, 18, 19, 20)
