隨著可攜式終端設備的發展,人類越來越依賴無線通訊技術來進行社交、商業等行為。若在建築物密集的都市當中,基地台之訊號可能會因建築物的遮蔽導致較差的收訊;而在人口稀少的郊區,用戶則可能處於基地台通訊範圍的邊緣或外部,導致訊號薄弱甚至沒有訊號。無線訊號透過使用中繼技術可以獲得通訊範圍的延伸,當訊號傳遞途中遭遇遮蔽物干擾時,亦可透過中繼站的訊號轉發來達到繞送的效果,進而解決收訊不良的問題。在本文中,我們考量到用戶具有移動性,並因而導致換手過程的差異,因此假設了可能的幾種情境,並整合分析,探討路徑差異導致延遲時間的差異,進而知曉如何選擇較佳的路徑以及基地台之間如何佈署較適當的情境。


With the fast development of mobile networks and technologies, many people have highly relied on wireless communication to carry out their everyday activities, like communicating with their family members or online shopping. However, in the downtown of a city, the radio signals that the user equipment (UE) receives from its nearby eNBs may be sheltered by its surrounding high buildings, resulting in poor mobile QoS. In a rural area, the user staying at the border of an eNB's communication range may also receive weak radio signals from the eNB. In fact, wireless signals emitted by an eNB, e.g., B, can be forwarded by a relay station so as to extend the communication range of B. When the signals radiated by B are interfered or sheltered, a relay station can also help to bypass the interference and shelters, thus effectively solving the problems of poor radio signals reception. In this paper, we deal with handover processes between two relay stations and between a relay station and an eNB, both of which are different from that between two eNBs. But handover concerning relay stations has its problems, e.g., if the base stations before and after handover are two relation stations and they belong to two neighbor eNBs, how to proceed the handover? Should the handover go through the two eNBs? Several handover scenarios are also explored in this study.
