1. A method for performing Internet protocol connectivity access network (IP CAN) session information pass-through, the method comprising:
- at a policy and charging rules function (PCRF) node;
receiving IP CAN session information from an access network-aware gateway as part of establishing an IP CAN session, wherein the IP CAN session information comprises at least one of;
user identity, user location, device identity, access network identifier, and handset type and wherein the IP CAN session information does not include policy and charging control (PCC) rules;
storing the IP CAN session information in an IP CAN session information cache;
performing, by the PCRF, IP CAN session lookup in the IP CAN session information cache based on an IP address provided by a deep packet inspection (DPI) node to locate the IP CAN session information; and
forwarding at least a portion of the IP CAN session information to the DPI node for use to perform DPI functions, and by receiving, storing, performing, and forwarding the IP CAN session information to the DPI node, the PCRF performs IP CAN session information pass-through;
wherein receiving the IP CAN session information includes receiving IP CAN session information in a first format and further comprising translating the IP CAN session information, at the PCRF, into a second format before forwarding the IP CAN session information to the DPI node.

Abstract
Methods, systems, and computer readable media for performing PCRF-based IP CAN session information pass-through are disclosed. According to one method, a policy and charging rules function (PCRF) receives Internet protocol connectivity access network (IP CAN) session information from an access network-aware gateway. The PCRF forwards at least a portion of the IP CAN session information to a deep packet inspection (DPI) node.

9. A system for performing Internet protocol connectivity access network (IP CAN) session information pass-through, the system comprising:
-
an IP CAN session information cache for storing IP CAN session information, wherein the IP CAN session information does not include policy and charging control (PCC) rules; and a policy and charging rules function (PCRF) node including; a communications interface for receiving the IP CAN session information from an access network-aware gateway, wherein the IP CAN session information comprises at least one of;
user identity, user location, device identity, access network identifier, and handset type, and for performing IP CAN session lookup in the IP CAN session information cache based on an IP addressed provided by a deep packet inspection (DPI) node to locate the IP CAN session information; andan IP CAN session information pass-through module for receiving the IP CAN session information from the communications interface and for forwarding at least a portion of the IP CAN session information to the DPI a node for use to perform DPI functions, and by receiving, storing, performing, and forwarding the IP CAN session information to the DPI node, the PCRF performs IP CAN session information pass-through; wherein the communications interface is configured to receive the IP CAN session information in a first format and the PCRF node further comprises a translation module configured to translate the IP CAN session information into a second format before forwarding the IP CAN session information to the DPI node. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
