Abstract
In one embodiment, at least one grouping message is broadcast from a network element. The grouping message causes an access terminal (AT) in the communications network to regard the at least first and second subnets as both being members of a same subnet group. Location information and a maximum distance parameter associated with at least one area and configured to create a buffer zone along a border between the first and second subnets are broadcasted from the network element to the AT. The AT is prevented from sending a subnet identifier request message when the AT has, as an origin area, an area of the first subnet in the buffer zone and the AT travels to an area of the second subnet in the buffer zone. Session transfers are performed outside the buffer zone triggered by distance based location update messages, thus preventing session transfer ping-ponging.
