METHOD AND APPARATUS FOR TRAFFIC CLASSIFICATION

摘要

A Policy and Charging Rules Function server (PCRF) of a Policy and Charging Control ( PCC) Architecture for deciding control rules applicable to user traffic flows to be inspected in accordance with applicable telecommunication protocols for each traffic flow by a Policy and Charging Enforcement Function server with Deep Packet inspection capabilities ( PCEF DPI) of the PCC Architecture. The PCRF includes a database having a list of protocols used in the user tialYtc flow s The PCRF includes an interface unit which receives a query from the PCEF DPI about applicable control rules for an IP Connectivity Access Network (IP CAN) session established for a user at the PCEF DPl The PCRF includes a processing unit which sends the applicable control rules for the IP CAN session and the list of protocols through the interface unit to the PCEF DPl. A Policy and Charging Enforcement Function server having Deep Packet Inspection capabilities (PCEF DPI) of a Policy and Charging Control (PCC) Architecture. A method of a Policy and Charging Rules Function server (PCRF) of a Policy and Charging Control (PCC) Architecture. A method of a Policy and Charging Enforcement Function server having Deep Packet inspection capabilities (PCFF DPI ) of a Policy and Charging Control (PCC) Architecture.
