System and method for correct routing and enforcement policy in a network having address or port translation

摘要

The present invention incorporates an intermediary proxy rules device that has access to information regarding network address and port bindings or network address and port translations. This intermediary function communicates translated address information to other devices on the network, such as the policy and charging rule function and policy and charging enforcement function. The full communication and coordination of this information coordinates correct translation address information and other necessary information to these PCRF and PCEF devices, which eliminates many of the problems associated with the session set-up and maintenance with other networks.
