Patent ID: 8611296

Claim:
A method of a gateway node of a first packet-switched data network selecting a first channel for transferring a tunneled data packet to a destination packet data protocol address of a mobile node provided service in the first network, wherein the gateway node is configured to select the first channel from a plurality of channels configured to transfer data packets to the destination packet data protocol address of the mobile node, wherein the tunneled data packet is sent from a correspondent node and tunneled by a tunneling node of a second network external to the first network, the method comprising: sending a data packet comprising data from the correspondent node to the mobile node; after sending the data packet, including the packet data protocol address of the correspondent node in a first data packet filter of the first channel; the tunneling node including the packet data protocol address of the correspondent node in the tunneled data packet; and the gateway node selecting the first channel by matching the packet data protocol address of the correspondent node to the first data packet filter associated with the first channel.
