Abstract
An ANC is formed to 'dummy fill' a neighbor list that is to be transmitted to a mobile terminal that is presently located in a border cell with neighboring BTSs for which a hand-off request cannot be granted. Accordingly, while a hand-off cannot occur to a BTS of a proximate cell that does not qualify as a neighbor because it is serviced by a different ANC in a 1xEVDO network, identifying the BTSs of the non-neighbor and proximate cells ('dummy list BTSs') prompts the mobile terminal to request a hand-off to a dummy list BTS when the BTS provides a better pilot signal. Because the ANC can readily identify the BTS from the dummy list, it knows that a hand-off cannot be facilitated therefor. Accordingly, the ANC instructs the mobile terminal to drop the call (data packet connection). Because many wireless data packet networks utilize at least a subset of established IP protocols and are able to establish point-to-point protocol communication links (higher layer communication links), commanding a mobile terminal to drop the call is a command to drop the call at the lower layers. The point-to-point protocol communication link is then resumed and the effect of a hand-off is achieved.
