SERVICE REDIRECTION FROM A POLICY AND CHARGING CONTROL ARCHITECTURE

摘要

For authorizing redirection services in a policy and charging control architecture, a policy and charging control rules function (PCRF) server determines control rules and redirection information per service in an internet protocol connectivity access network session, and a policy charging and enforcement function (PCEF) device receives control rules and redirection information per service basis, determines redirection per service request, and triggers the redirection. Upon a first request for a service, the PCEF device returns a redirection message with a redirection identifier; and upon completion of the service redirection, the first request for the service reaching the PCEF, the PCEF verifies the service is authorized and submits a service allowance toward the service server in charge of the service. Methods are also disclosed.
