摘要

在各代行動通訊系統中，第五代行動通訊系統(5th generation mobile networks; 5G)作為下一代行動通訊系統，世界各國都在爭相研究，而本論文由第四代行動通訊系統(4th generation mobile networks; 4G)的S1AP(S1 Application Protocol)協議切入，並引入NAS(Non Access Stratum)、GTP(GPRS Tunnelling Protocol)、GTPv2等協議，此外，也對整體使用者裝置(User Equipment; UE)接入網路的流程進行研究，最後再透過實作，融合上述協議與流程的知識，最後達成讓UE連上網路的目的。
本研究期望能以此實驗經驗作為研究5G系統的基石，製作出我們能了解、並能依此客製化的5G核心網路。

In all generation mobile networks, 5G(5th generation mobile networks), as the next generation mobile networks, is researched by almost all world's most powerful nations. I start the work from the S1AP(S1 Application Protocol) protocol of 4G, and further introduce NAS(Non Access Stratum), GTP(GPRS Tunnelling Protocol), GTPv2 protocols. In addition, I mainly put effort into researching the UE Attach Procedure. At last, combining the knowledge of the protocols and procedures introduced above, I implement the 4G CoreNet to make UE attached to the net and be able to surf the net.
I look forward to letting this research be the foundation of surveying the 5G CoreNet system. With knowing the structure of 5G CoreNet, we can make our own 5G CoreNet and customize it as we like.
