因應時代趨勢所求,無線通訊技術不斷的發展,造就了同一世代有多種不同的無線通訊技術共存於現今。許多城市大都有佈建Wi-Fi的節點,在節點的服務範圍內,皆能隨時隨地的連上網路。但由於Wi-Fi的服務範圍小,常受地形建築物的影響,導致訊號衰減或中斷無法連線,此時行動台可將訊號移交至LTE-Advanced的基地台,透過訊號服務範圍較大的基地台,確保服務品質。反之,連接LTE-Advanced時,移動遠離訊號源一定距離也可能因訊號衰減,必須移交至較近的節點。因此,本論文提出以LTE-Advanced與Wi-Fi的移交管理決策演算法,能適時有效的判別使用者需求進而決定是否移交與移交的目標。而在連接Wi-Fi節點時,會比一般連接3G或4G網路更加耗電,本研究的演算法中,亦提出延長行動台電池使用壽命的決策。經實驗模擬,本演算法可以有效降低使用者發生斷訊的機率,延長行動台電池使用時間。

In response to the demands of our times, the continuous development of wireless communication technology has led to the coexistence of multiple types of wireless communication technologies. Many cities have deployed Wi-Fi nodes that provide ready access to the internet; however, Wi-Fi nodes have a small service range, and terrain and buildings can cause signal attenuation or disconnections. Mobile station s can be used to transfer the signal to LTE-Advanced base stations to extend the service range; however, the signal decays with distance from the source, resulting in the need to transfer the signal to a nearer node. This study developed a decision algorithm for the transfer and management of LTE-Advanced and Wi-Fi services, which can determine user needs in a timely and effective manner and decide whether transferring the signal is required. The proposed algorithm also takes into account the power requirements of the available connections in order to extend the battery life. Simulations show that the proposed algorithm can effectively reduce the probability of disconnection and extend battery life.
