Mobile broadband wireless access system for transferring service information during handover

The present invention is related to transmitting quality of service (QoS) information of a target base station for admitted service flows during a handover operation. The invention comprises providing a service to a mobile station from a serving base station and receiving at the serving base station a handover request from the mobile station. The serving base station the provides a handover notification to a target base station, wherein the handover notification comprises a QoS parameter associated with the service. The serving base station then receives from the target base station a handover notification response, wherein the handover notification response comprises service level prediction information that is determined in response to the QoS parameter associated with the service. Finally, the serving base station provides a handover response to the mobile station, the handover response comprising the service level prediction information.
