A method may include determining whether each of a plurality of target base stations is capable of providing a fast ranging opportunity to a mobile station served by the serving base station, and, for each of the plurality of target base stations which is capable of providing the fast ranging opportunity to the mobile station, determining an action time after which the target base station can send an uplink map to the mobile station, the uplink map indicating when the mobile station should send a fast ranging request. The method may also include sending a handover message to the mobile station, the handover message indicating whether each of the plurality of target base stations is capable of providing the fast ranging opportunity to the mobile station and indicating the action time after which the target base station can send the uplink map to the mobile station.
