Method of and system for providing quality of service in IP telephony
First Claim
1. A device-implemented method of providing quality of service in an IP telephony session between a calling party and a called party, the method comprising:
- assigning, using a session initiated protocol (SIP) server, and at a first device-implemented access control manager, a temporary IP proxy address to the called party the first device-implemented access control manager to couple an IP network to a second network at a first access point;
assigning, using the SIP server, and at a second device-implemented access control manager, a temporary IP proxy address to the calling party, the second device-implemented access control manager to couple the IP network to the second network at a second access point;
transporting IP media traffic, during the session, between the calling party and the first device-implemented access control manager; and
transporting IP media traffic, during the session, between the called party and the second device-implemented access control manager.

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.

8. 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 connected between an IP telephony network and an ATM network, the first device providing bi-directional translation between IP media traffic, associated with the calling party and ATM traffic, associated with the called party; a second device connected between the IP network and the ATM network, the second device providing bi-directional translation between IP media traffic, associated with the called party and ATM traffic, associated with the calling party; a session initiated protocol (SIP) server to assign a temporary IP session proxy destination address for the called party at the first device and to assign a temporary IP session proxy source address for the calling party at the second device, and to transport, during the IP telephony session, the IP media traffic between the calling party and the first device and between the called party and the second device; and an intelligent control layer to establish a virtual circuit through the ATM network for the IP telephony session between the calling party and the called party, where the first device and the second device are assigned on a per session basis. - View Dependent Claims (9, 10, 11)

12. A device-implemented media service control point for enabling quality of service an internet protocol telephony session, the device-implemented media service control point comprising:
-
a session initiated protocol (SIP) server to assign a temporary IP proxy destination address to a called party at a first device-implemented access control manager, the first access control manager to couple an IP network to an ATM network at a first access point, where the SIP server is further to; assign a temporary IP proxy source address to a calling party at a second device-implemented access control manager, the second device-implemented access control manager to couple the IP network to the ATM network at a second access point; transport IP media traffic, during the session, between the calling party and the first device-implemented access control manager; and transport IP media traffic, during the session, between the called party and the second device-implemented access control manager. - View Dependent Claims (13, 14, 15)

16. A device-implemented method for providing QOS in a telephony system comprising:
-
receiving a call request from a calling party designating a called party; assigning, using a session initiated protocol (SIP) server, and at a first device-implemented access control manager, a temporary IP proxy address to the called party, the first device-implemented access control manager being configured to couple an IP network to a second network at a first access point; assigning, using the SIP server, and at a second device-implemented access control manager, a temporary IP proxy address to the calling party, the second device-implemented access control manager to couple the IP network to the second network at a second access point; and exchanging call media between the first device-implemented access control manager and the second device-implemented access control manager via the second network based on the assigned temporary IP proxy addresses. - View Dependent Claims (17, 18)
