COMBINING INTERNET PROTOCOLS FOR SESSION SETUP, TEARDOWN, AUTHENTICATION, AUTHORIZATION, AND ACCOUNTING USING THE DIFFERENTIATED SERVICES MODEL.

摘要

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 (1) and tearing down a session, while maintaining Authentication, Authorization, and Accounting (AAA) policies (2). 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.
