1. A method for communicating with an IP network over multiple links using multiband operation, comprising:
- receiving a first data packet at a mobile terminal;
identifying from a plurality of wireless networks one or more viable communication links between the mobile terminal and the IP network;
associating a set of link metrics with each of the one or more viable communication links and saving the set of link metrics to a link profile;
selecting a first selected link from one or more viable communication links based on the link profile of the first selected link; and
sending the first data packet to the IP network over the first selected link;
sending the link profile to a home node on the IP network associated with the mobile terminal;
receiving and storing the link profile at the home node;
receiving a second data packet at the home node to send to the mobile terminal;
selecting a second selected link from the plurality of communication I inks based on the link profile of the second selected link;
sending the second data packet to the mobile terminal over the second selected link.

Abstract
Dynamic link switching of forward and reverse links for a wireless connection in the presence of multiple wireless networks. A mobile terminal maintains simultaneous links to multiple wireless networks, including WLANs, WPANs and proprietary networks operating over unlicensed and subscription networks. The mobile terminal generates a link profile used for dynamic reverse link selection by the mobile terminal and for dynamic forward link selection by a home node. Dynamic link selection is based on priority factors for data packets considering characteristics of all viable links.

20. A mobile multilink wireless access system using multiband operation comprising:
-
a mobile terminal connected to a first link selector, wherein the mobile terminal comprises;
an interface for connecting to a plurality of wireless networks; and
a transceiver adapted to establish a communication link to an access point over any one of the plurality of wireless networks accessible through the interface; and
an IP network, wherein the IP network comprises;
an address associated with a plurality of access points;
a home node connected to a second link selector wherein the home node comprises a network address associated with the mobile terminal and logic to communicate with each of the plurality of access points; and
wherein, the first link selector comprises logic for;
monitoring each communication link established by the transceiver;
establishing a set of link metrics associated with a communication link and saving the set of link metrics to a link profile;
sending the link profile to the second link selector;
selecting a first link based on the link profile; and
communicating with the access point associated with the first link; and
wherein, the second link selector comprises logic for;
receiving and storing the link profile;
selecting a second link based on the link profile; and
communicating with the access point associated with the second link; and
wherein the access point comprises logic to communicate with the home node. - View Dependent Claims (21, 22, 23, 24, 25)
