一個基於動態連結框架實作的彈性5G核心網路

Abstract

未來的5G網路將不再只是一個用於服務一般手機用戶的行動網路，其將也需要服務各式各樣不同的穿戴式裝置、傳感器、車子、家電、虛擬實境眼鏡、機器人等。然而，由於這些不同裝置的特性都相差非常大，因此未來的5G網路勢必需要設計的足夠有彈性才能夠適應各式各樣不同的連網需求。 本篇論文將提出一個稱之為RECO的可重組核心網路架構，透過這個架構，我們將展現如何能夠針對不同裝置的特性有效率的客製化出對應的核心網路元件。此外，我們也依照RECO的架構實作出一個稱之為RECO MME的可重組移動管理實體，RECO MME主要是用來展現與驗證我們所提的RECO架構。另外，本篇論文也將著重於探討如何實作RECO MME內的動態連結框架，首先我們會仔細地介紹何謂動態連結，接著再利用動態連結的技術實作出一個用於未來彈性5G核心網路的動態連結框架。最後，我們將於近期開源出我們所開發的RECO MME，如此大家都能夠利用它來進行5G核心網路的相關研究。

It is envisioned in the future that not only smartphones will connect to cellular networks, but also all kinds of different wearable devices, sensors, vehicles, home appliances, VR headsets, and robots etc. However, since the characteristics of these different devices differ largely, people argue that future 5G communication systems should be designed to elastically accommodate these different scenarios. In this thesis, we propose a reconfigurable core network called RECO that demonstrates how to implement customized virtual network entities efficiently to suit for different types of users with different characteristics. We then implement a reconfigurable MME called RECO MME which verifies our proposed RECO architecture. Besides, this thesis particularly focuses on the dynamic linking framework used in our RECO MME. We explain what is dynamic linking thoroughly and show how to use it to implement a framework used for achieving a flexible 5G core network. Finally, we will open source our RECO MME in the coming future so that the whole research community can take benefit out of it.
