有賴於4G無線通訊技術，人們可以隨時隨地利用智慧型裝置在網路上漫遊，並且享受高傳輸速率的服務。然而，5G技術來勢洶洶，尤其是未來的網路架構將要能夠同時應對不同種服務，該如何利用單一的基礎建設提供一個具有彈性、快速建置、資源可擴充性高、以及能夠整合異質性網路的架構是一件重要的事情。除此之外，該如何減低建置系統時所花費的成本，也是值得思考的問題。
有鑑於此，本論文著重在利用開源軟體提供一個基於5G白皮書之網路切片的架構。此架構可以藉由雲端運算、軟體定義網路(SDN)、以及網路功能虛擬化(NFV)來提供網路切片的功能。透過結合OpenStack、Docker、OpenAirInterface (OAI)、商用小細胞基站、以及虛擬私有網路，作為基礎設施的建置。並且以虛擬機為一個節點單位，透過模組之間排列組合來提供網路切片功能。除此之外，本論文實作了一套社交軟體、影像串流與辨識、以及飛行器的控制來驗證本系統，並且針對架構的資料傳輸效能進行測量。

Thanks to 4G wireless communication technology, people can use the intelligent device anywhere on the network roaming, and enjoy high transmission rate of service. 5G communication architecture will be able to simultaneously deal with different kinds of services. How to use a single infrastructure to provide a flexible, fast build, high resource scalability, and the ability to integrate heterogeneous network architecture is an important issue. In addition, how to reduce the cost of building the system is also worth of study.
In view of this, this thesis focuses on the use of open source software to implement a network slice architecture based on 5G white paper. This architecture can provide the functionality of network slicing by means of cloud computing, software definition network (SDN), and network functional virtualization (NFV). Through the integration of OpenStack, Docker, OpenAirInterface (OAI), commercial small cell base stations, and virtual private network one can build a 5G platform. Besides, this thesis uses in-house social communication software, video streaming and face detection, and the control of drone to verify the feasibility of the 5G system.
