METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR USING POLICY KNOWLEDGE OF OR OBTAINED BY A POLICY AND CHARGING RULES FUNCTION (PCRF) FOR NEEDS BASED FORWARDING OF BEARER SESSION TRAFFIC TO NETWORK NODES

摘要

The subject matter described herein includes methods, systems, and computer readable media for using policy knowledge of or obtained by a policy and charging rules function (PCRF) for needs based forwarding of bearer session traffic to network nodes. One exemplary system includes a PCRF. The PCRF includes a policy engine for identifying, using policy knowledge or obtained by the PCRF, zero or more network nodes hosting applications needed for processing packets of a bearer session. The PCRF further includes an application routing configurator for providing instructions to configure at least one configurable network element to forward bearer session traffic to any of the network nodes determined to be needed for processing packets associated with the bearer session and to bypass any of the network nodes not determined to be needed for processing packets associated with the bearer session.

1. A system for using policy knowledge of or obtained by a policy and charging rules function (PCRF) for needs based forwarding bearer session traffic to network nodes, the system comprising:
a PCRF including:
a policy engine for identifying, using policy knowledge of or obtained by the PCRF, zero or more network nodes hosting applications needed for processing packets of a bearer session; andan application routing configurator for providing instructions to configure at least one configurable network element to forward bearer session traffic to any of the network nodes identified as hosting applications identified as needed for processing packets associated with the session and to bypass any of the network nodes not identified as needed for processing packets associated with the session.
