An apparatus and method for compensating Quality of Service (QoS) during a handover of a Mobile Station (MS) by a serving Base Station (BS) and a target BS in a wireless broadband access system are provided. The method includes generating a message during a handover from the serving BS to a target BS, the message including at least one of a data transmission/reception time just before the handover, a size of a time window for which a data transmission/reception history is recorded in an accumulated way, and an amount of data transmitted/received during the time window, and transmitting the message to the target BS. The target BS can more accurately find a handover break time and the amount of data transmission/reception in the serving BS at the time the MS has been handed over to the target BS, enabling fast and adequate QoS compensation/correction for each QoS class, and thus facilitating flexible, efficient and accurate QoS provisioning regardless of controlled handover and uncontrolled handover. |
