隨著時代的進步，網路技術不斷地成長，新的無線網路協定如IEEE 802.11 (Wi-Fi) 、 IEEE 802.16 (WiMAX) 以及3GPP (3rd Generation Partnership Project) 提供網路使用者，不同的頻寬、不同的網路涵蓋範圍以及不同價格的選擇，如此多種不同無線網路形成的網路環境稱為異質無線網路環境。而隨著新的網路協定日漸成熟，各種寬頻無線設備推陳出新，同時面對如此多的網路設備，異質無線網路管理已成為一個相當重要的議題。傳統的網路管理應加以改進方可以管理異質的無線網路環境。 在異質無線網路管理中最大的問題是如何同時管理多個無線網路，並且能讓網管中心能正確且快速的得知各個無線網路的狀態是相當困難的。因此本論文提出了一個適用於異質行動網路的管理系統 (Heterogeneous Mobile Network Management System，簡稱為HMNMS)。本系統使用分散式的架構，在每個不同的行動無線網路中佈建一台HMNMS。每一台HMNMS可以跟鄰近的HMNMS互相分享行動網路的資訊，利用涵蓋範圍較小的基地台位置來當作量測涵蓋範圍較大的基地台訊號強度，善用使用者多個接取介面以及涵蓋範圍的特性來減少不必要的量測人力花費。本系統不僅提供網路管理者在異質的行動無線網路下，方便的監測和管理無線網路設備，更可以透過使用者所回報的訊號強度以及使用者的位置資訊來分析基地台的涵蓋範圍，適當的調整和佈建基地台的位置以建構網路無所不在的環境。 With the improvement of society, the technology of internet is growing constantly. New wireless internet agreement like IEEE 802.11 (Wi-Fi) 、 IEEE 802.16 (WiMAX) and 3GPP (3rd Generation Partnership Project) provide internet users have different options for different broadband, different internet field and different prices. Many different wireless internet form an internet environment. We called it Heterogeneous wireless network environment. With new internet agreement getting mature, a variety of broadband wireless equipment is developed. To administer heterogeneous wireless network is becoming a significant issue when we face so many internet equipment at the same time. Traditional internet administration should be improved to manage heterogeneous wireless network environment. The most important problem in the administration of heterogeneous wireless network is how to administer many wireless networks at the same time. And it’s quite difficult to let internet administration center know the status of each wireless internet correctly and fast. Therefore, the essay offers a management system which applied to Heterogeneous wireless network. (Heterogeneous Mobile Network Management System，call the HMNMS). The system uses separated construction to set up a HMNMS on every different mobile wireless network. Every HMNMS will be able to share the information of Mobile Network with neighboring HMNMS. To measure intensity of message for bigger shooting range base with the location of smaller shooting range base. Making good use of several interfaces to decrease unnecessary cost on measurement. The system not only offers a convenient monitoring and manages wireless network equipment under Heterogeneous Mobile Network, but also analyze covering range of base through the intensity of message of the users and the location of users. With proper adjustment and the setting up of base location, to create the environment that internet exists everywhere.
