在第五代行動通訊技術(5th generation mobile networks, 5G)發展下，行動通訊(Mobile Communication)相關之設備將大幅成長，行動通訊設備大量增加中，行動通訊的傳輸效能對營運商的服務影響非常大。而影響營運商行動通訊傳輸效能的原因之一是營運商在建置基站(Base Station, BS)及基站範圍內之使用者，在基站覆蓋範圍內不同設備的使用者狀態會導致傳輸效能影響，且增加基站的負擔，因此本論文透過網路切片(Network Slicing, NS)來解決行動通訊服務品質及傳輸之問題。
本論文藉由營運商提供之基站範圍來做網路切片的技術，並提高大量使用者狀況下的基站吞吐量(throughput)，以及使用者連接滿意度(User Satisfaction)。並且比較了比例公平演算法(Proportional Fairness, PF)、排程演算法(First Come First Serve, FCFS)及所提出的優化網路切片(Proposed Network Slicing, PNS)模型演算法，以利營運商建置基站時調整參數，並從而改善使用者連接滿意度。
實驗結果顯示本論文提出的演算法，在大量使用者下能得到更好的連接滿意度及基站平均吞吐量。本論文的網路切片模型可協助營運商了解在不同使用者數量下每個演算法模型的效能，並透過調整基站建置的參數，減少使用者連接滿意度下降及提高基站平均吞吐量。

With the development of the 5th generation mobile networks (5G), the equipment related to mobile communication will grow significantly. With the increase of mobile communication equipment, the transmission performance of mobile communication will have an impact on the service of operators. One of the reasons that affect the transmission performance of the mobile communication of the operator is that the operator builds the base station (BS) and the users within the BS range. The user status of different devices within the coverage of the BS will affect the transmission performance. And increase the burden of the BS. This paper uses Network Slicing (NS) to solve the problem of mobile communication service quality and transmission.
This paper uses the BS range provided by the operator to do NS, and improve the BS throughput and user satisfaction under the condition of multi-users. And compared the Proportional Fairness (PF), the First Come First Serve (FCFS) algorithm, and the Proposed Network Slicing (PNS) model algorithm. In order to facilitate operators to adjust parameters when building BS and improve user satisfaction.
The experimental results show that the algorithm proposed in this paper can obtain better satisfaction and average BS throughput under multi-users. In this paper, the NS model support operators to understand the performance of each algorithm model under different numbers of users, and by adjusting the parameters of BS construction, improve the user satisfaction and average throughput of BS.
