Patent ID: 7545780

Claim:
A method for a subscriber unit capable of operating in a cellular network and a wireless local area network (WLAN), configured to perform: receiving an indication of a classification of a first group of selected transmission control protocol/internet protocol (TCP/IP) sessions and a second group of TCP/IP sessions, wherein the first group and the second group are classified based on type of flow; for packets of the first group of selected TCP/IP sessions, transferring those packets by encapsulated delivery to a desired node on the Internet via cellular network and the WLAN by inserting into a header of those packets routing information to a specified node in the cellular network, while the cellular network and the WLAN are connected to the Internet, wherein packets are transferred to a desired node on the Internet via the WLAN; for packets of a second group of selected TCP/IP sessions, transferring those packets directly to a desired node on the Internet via the WLAN, without routing through the cellular network, wherein the packets of the first group and the packets of the second group are defined by a source IP address, a destination IP address, a source port, a destination port, and a transport protocol type; and receiving an indication of a priority level of a traffic loading, wherein a packet data session is directly routed through the WLAN if the traffic loading is high and the packet data session is routed through the WLAN and the cellular network if the traffic loading is low.
