20120069797 | METHOD FOR A COMMUNICATION NODE WITH A PLURALITY OF COMMUNICATION INTERFACES TO NOTIFY DYNAMIC PATH SETUP AND ASSOCIATES APPARATUS THEREOF - A User Equipment (UE) that is simultaneously connected (via a 3G connection and a non-3G connection) to a Packet Data Network Gateway (P-GW) can direct how traffic flows would be routed from the P-GW to the UE. Typically, the P-GW would setup the 3G communication path to the UE when it receives a downlink data packet directed to the UE's 3G path. If the P-GW uses such logic for setting a communication path to the UE without knowing the user's actual intention, this might result in the case where the user would experience some service degradation for ongoing session. In addition, it is possible that the packets filters for a first UE interface are not utilized due to the erroneous setting of the packets filters for a second UE interface.
