First Claim
1. A method for selecting a wireless device network communication link to a destination host through one of a plurality of available wireless protocol links, the method comprising:
- selecting a first protocol link from the plurality of available wireless protocol links based on predetermined criteria;
establishing a first network connection through the first protocol link;
detecting a change in status of the predetermined criteria of the first protocol link;
selecting a second protocol link from the plurality of available wireless protocol links based on the change in status of the predetermined criteria;
establishing a second network connection through the second protocol link; and
terminating the first network connection through the first protocol link, such that the wireless device does not lose network communication with the destination host.

Abstract
A method for providing network communication to a wireless device through a plurality of wireless protocol links. A first protocol link from the plurality of wireless protocol links is selected based on some predetermined criteria. A first network connection is established through the first protocol link. A second protocol link from the plurality of wireless protocol links is selected based on the change in status or condition of the first protocol link with respect to the predetermined criteria. A second network connection is established through the second protocol link, and the first network connection through the first protocol link is terminated.

19. A wireless network communication system, comprising:
-
a-plurality of wireless protocol base units each of which is adapted to provide a wireless protocol link to a network destination host;
a wireless communication device adapted to provide a wireless connection to the network through a first wireless protocol link of the plurality of protocol links, and configured to monitor the plurality of wireless protocol links for availability based on predetermined criteria, such that the first wireless protocol link can be replaced with another protocol link from the available protocol links when a status of the first wireless protocol link changes; and
a Control Center configured to manage mapping of network addresses to replace the first wireless protocol link with another protocol link from the available protocol links without disrupting communication between the wireless communication device and the destination host. - View Dependent Claims (20, 21, 22)

27. A wireless device for enabling wireless connection to a network, the wireless device comprising:
-
a transceiver configured to receive forward link signals that have been transmitted from a plurality of base units providing a plurality of protocol links, and to transmit appropriately-powered reverse link signals to the plurality of base units;
a digital signal processor configured to demodulate and decode the forward link signals, and to modulate and encode the reverse link signals; and
a mobile connection logic configured to provide the wireless connection to the network through a first wireless protocol link of the plurality of protocol links, the mobile connection logic configured to monitor the plurality of wireless protocol links for availability based on predetermined criteria, such that the first wireless protocol link can be replaced with a second protocol link from the available protocol links when a status of the first wireless protocol link changes. - View Dependent Claims (28, 29)
