Patent ID: 7502349

Claim:
A method for conducting wireless communication between a mobile device and a network, the method comprising: initiating a first session with a first gateway when the mobile device is in a first zone associated with the first gateway; initiating a second session with a second gateway when the mobile device is in a second zone associated with the second gateway; and when the mobile device is in the second zone, directly servicing the second session using the second gateway, and servicing the first session using the first gateway by passing data between the first gateway and the second gateway; wherein the pathway for data traffic between the mobile device and the network is based on the zone in which a session is initiated, so that if both the first and second sessions are open and being serviced when the mobile device is in the second zone, data traffic for the first session is tunneled through the first and second gateways to the network, and data traffic for the second session is passed through the second gateway to the network without being tunneled through the first and second gateways.
