隨著無線網路的蓬勃發展,許多城市都有佈建WiFi的節點,在節點的服務範圍皆能隨時隨地的連上網路,但WiFi的服務範圍小,常會受地形建物的影響,使得訊號減弱或中斷無法連線。因此,本論文提出以WiMAX與WiFi整合系統之智慧型垂直移交演算法,使得WiFi可以與WiMAX作結合,將訊號減弱的行動台移交到範圍大的輕載基地台中,可以持續保持正常通話。並將正在使用頻道的使用者從一個壅塞的基地台移到較輕載的基地台,並且將所釋放的頻道給抵達壅塞基地台的移交使用者使用,透過模擬結果證明,此演算法能有效提升通訊服務品質。

Following the wireless network to develop rapidly, many cities have deployed WiFi nodes. Users can connect to the Internet anytime and anywhere in the service ranges of these nodes. The service ranges of WiFi nodes are small, users often subject to the signal weakened or interrupted from the influence of terrain and building cannot connect. Therefore, this paper proposes an intelligent vertical handoff algorithm for the integration networks of WiMAX and WiFi. WiFi and WiMAX combined in the module, it make the mobile stations (MS) of signal weakened can handoff to light-load base stations (BS) and can maintain normal call continuity. Also, an ongoing-call user can hand-over from the original congested BS to others light-load BS, it will release the using channel resource to the just reached handoff-call or new-call on original congested BS. Through the simulation results prove that this algorithm can effectively enhance the quality of communications services.
