15. A method for hand-off trigger at access technology borders, comprising:
triggering a hand-off a mobile station in communication with a first carrier having a first technology type to a second carrier having a second technology type, the mobile station synchronized with the second carrier and located in a border area, the border area including at least one sector covered by at least two carriers having different Radio Access Technologies (RATs) including the first technology type and the second technology type, if at least one of (a) a channel condition of the second carrier is above a first threshold value, the mobile station fails to receive a second message in response to a first message sent to the first carrier in a time interval, and a number of the first message have already been sent to the first carrier; and (b) the channel condition of the second carrier is above a first threshold value, the mobile station receives the second message in response to the message sent to the first carrier within the time interval, and first the message indicates that a distance from the mobile station to a current base station of the first carrier is above a distance threshold. - View Dependent Claims (16, 17, 18, 19, 20)

21. A method for hand-off trigger at access technology borders, comprising:
triggering a hand-off of a mobile station in communication with a first carrier having a first technology type to a second carrier having a second technology type if the mobile station exits a border area, the border area including at least one sector covered by at least two carriers having different Radio Access Technologies (RATs) including the first technology type and the second technology type, the mobile station having been synchronized with the second carrier upon entering the border area. - View Dependent Claims (22, 23, 24, 25)
