20110219426 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR ENHANCED SERVICE DETECTION AND POLICY RULE DETERMINATION - Methods, systems, and computer readable media for enhanced service detection and policy rule determination are disclosed. According to one method, a policy charging and rules function (PCRF) node requests, from a deep packet inspection (DPI) node notification of detection of traffic relating to a service. The DPI node identifies at least one traffic classifier usable to detect traffic corresponding to the service, uses the traffic classifier to detect traffic corresponding to the service, and notifies the PCRF of the detection and of the traffic classifier. The PCRF node receives 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. | 09-08-2011 |
