Abstract
Official abstract text for this publication.
A method of handling packets sent across a packet switched network comprising a policy server acting as a policy and charging rules function. The method comprises providing a first set of policy rules at said policy server, and installing these from the policy server into an access gateway over a first service control session. These policy rules cause packets belonging to a given IP session to be diverted by the access gateway to a network address translator. At the network address translator, an IP source address of said packets is translated into a translated IP source address identifying a deep packet inspection node. The network address translator forwards the packets to the deep packet inspection node configured to perform deep packet inspection of IP packets.
