Patent attributes
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-DPI 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-DPI. 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.
