Abstract
Systems and methods for providing an interface to communicate policy information from a policy server to a policy enforcement point are presented. An external policy server is used to implement and provide various policies to a policy enforcement point for enforcement on subscriber sessions and traffic flows of a mobile subscriber. A policy enforcement point can request instructions from the policy server using an access-request message and receive from the policy server unsolicited instructions with a change-of-authorization message. Policies for application to a subscriber session or traffic flow are included in the message from a policy server to the policy enforcement point. Other messages such as a disconnect message are used to terminate a subscriber session.
