Abstract
Fine grained RAN aware traffic prioritization in spectrum constrained modern wireless networks which support differentiated service plans uses cell load metrics supplied to a Fine grained Traffic flow Prioritization Engine (FTPE) with and without the assistance from a client side collection module, Peer Agent (PA), at the mobile. Knowledge about a mobile's subscription plan is derived from a Subscription Profiles Repository (SPR). Dynamic control on traffic prioritization is applied through operator policy control engines, Policy and Charging Rules Function (PCRF) module. The FTPE works with flexible flow aggregation rules to simplify and scale prioritizing, blocking, and deferring decisions. The FPTE may apply Deep Packet Inspection (DPI) techniques to identify application flows, and uses hierarchical queue disciplines to achieve the necessary flow control. The FPTE may also instead use an adjunct DPI to perform the flow identifications.
