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 packet.

Token-based correlation of control sessions for policy and charging control of a data session through a NAT

The invention comprises methods and arrangements for Policy Decision Point discovery in a roaming or handover scenario in an IP network (IN) comprising a plurality of network elements. The invention introduces a Re-direct Policy Decision (RPDF) Function which can deliver addresses to PDPs associated to a certain Mobile Terminal. The RPDF comprises a memory for storing addresses (APDPA, SPDPA) of Policy Decision Points and Mobile Terminals. The RPDF makes it possible for a network element, e.g. an application function, a policy enforcement point or another policy decision point, to find a Policy Decision Point associated to the Mobile Terminal.

Policy management in multi-access scenarios

A communication system includes a user equipment (UE)and a gateway. The UE () sends data packets on one or more bearers () to the gateway. One or more packet filters () are installed in the UE () for associating the data packets with the bearers (). A decision is performed if installation of a new packet filter () in the UE () is required to map the data packets of indicated data traffic to a particular bearer (). The result of the decision may then be indicated from a policy controller () to a gateway () and/or from the gateway () to the UE (). Depending on the result of the decision, the gateway may initiate signaling of the new packet filter () to the UE () and/or the UE () may install the new packet filter ().

Controlling packet filter installation in a user equipment

A method, a gateway node, a policy control node and a infrastructure network for handling a handover of a User Equipment communicating wirelessly with the infrastructure network. A first gateway node receives handover information indicative of a handover of the user equipment between two radio access networks the first gateway node determining a bearer control mode on the basis of the handover information the first gateway node transmitting control information determined on the basis of the bearer control mode to a policy control node the first gateway node controlling the bearer binding on the basis of the bearer control mode.
