Patent ID: 8041825

Claim:
A system comprising: a policy enforcement point in communication with a mobile subscriber that maintains one of a subscriber session and a traffic flow; and an interface to the policy enforcement point in communication with a policy server for dynamic update of quality of service policy enforced on the one of a subscriber session and a traffic flow, wherein the policy enforcement point: requests a requested quality of service policy from the policy server using a Radius-based access-request message including information identifying the one of a subscriber session and a traffic flow; receives at least one of a Radius-based access-accept message and Radius-based access-reject message from the policy server in response to the requested quality of service policy; receives from the policy server with a Radius-based change-of-authorization message an unsolicited quality of service policy that is independent of the requested quality of service policy; and enforces at least one of the requested quality of service policy and the unsolicited quality of service policy on the one of a subscriber session and a traffic flow, wherein the unsolicited quality of service policy is generated due to modification of the quality of service policy enforced on the one of a subscriber session and a traffic flow, and wherein the modification of the quality of service policy is related to an anticipated flow of data traffic to the policy enforcement point.
