Abstract

A method for combining Internet protocols in a Differentiated Services model environment is described. The Session Initiation Protocol (SIP) and Common Open Policy Service (COPS) are combined together to provide methods of setting up a session and tearing down a session, while maintaining Authentication, Authorization, and Accounting (AAA) policies. The Open Settlement Policy (OSP) is also combined with SIP and COPS. This combination provides for an interchange of parameters between session setup, teardown, authorization, policy, Quality of Service (QoS), and usage reporting

Claims

1. A method for providing Internet Protocol (IP) communications over at least one network with Quality of Service (QoS), comprising the steps of:

establishing at least one QoS policy in at least one network node;

initiating a communication session between at least one first end client device and at least one second end client device;

providing information to at least one server of the communication session, said information including at least one of resource usage, policy, authorization, authentication, and accounting information;

providing information to at least one router of the communication session, said information including at least one of resource usage, policy, authorization, authentication, and accounting information; and

establishing a communication session between said at least one first end client device and said at least one second end client device.
