Methods, systems, and computer readable media for enhanced service detection and policy rule determination

A system for enhanced service detection, the system comprising:

• a policy charging and rules function (PCRF) node for requesting notification of detection of traffic relating to a service;
• and
• a deep packet inspection (DPI) node for receiving the request from the PCRF node, for identifying at least one traffic classifier usable to detect traffic corresponding to the service, for using the at least one traffic classifier to detect traffic corresponding to the service, and for notifying the PCRF node of the detection and of the at least one traffic classifier;
• and
• wherein the PCRF node, in response to receiving notification of detection of the traffic corresponding to the service and the at least one traffic classifier, determines a policy rule based on the at least one traffic classifier and communicates the policy rule to a policy enforcement node.

A non-transitory computer readable medium having stored thereon executable instructions that when executed by the processor of a computer control the computer to perform steps comprising:

• at a policy charging and rules function (PCRF) node, requesting, from a deep packet inspection (DPI) node, notification of detection of traffic relating to a service;
• at the DPI node, identifying at least one traffic classifier usable to detect traffic corresponding to the service, using the at least one traffic classifier to detect traffic corresponding to the service, and notifying the PCRF node of the detection and of the at least one traffic classifier;
• and
• at the PCRF node, determining a policy rule based on the at least one traffic classifier and communicating the policy rule to a policy enforcement node.
