The present disclosure proposes a handover management method and a base station having a smart antenna using the same method. A transceiver of the base station transmits and receives wireless data. An interface controller of the base station transmits a source beam-forming information and receives a target beam-forming information. A processing circuit of the base station is coupled to the transceiver circuit and the interface controller and is configured for transmitting the source beam-forming information when switching to a setting of the smart antenna corresponding to the source beam-forming information and receiving the target beam-forming information using the interface controller, recording the source beam-forming information and the target beam-forming information as a beam-forming pair to a history of a handover when performing the handover, grouping the beam-forming pair in the history into beam-forming pair groups, and determining handover parameters for each of the beam-forming pair groups respectively.
