Abstract
A connection is established between an access terminal and a first radio network controller through a first radio node. The first radio node is controllable primarily by the first radio network controller. The connection is maintained with the first radio network controller as the access terminal moves from a coverage area of the first radio node toward a coverage area of a second radio node. The second radio node is controllable primarily by a second radio network controller and controllable subordinately by the first radio network controller. A connection is also established through the second radio node. Upon a fulfillment of a predetermined criterion, the connection is transferred from the first radio network controller to the second radio network controller.
