窄頻物聯網是第三代合作夥伴(3rd Generation Partnership Project , 3GPP)計劃用於支援廣域物聯網的標準，甚至作為第五代行動通訊網路(Fifth Generation Mobile Networks, 5G)中大規模機器型通訊(Massive Machine-Type Communications , mMTC)項目的基礎。在窄頻物聯網系統中，本篇論文提出一可相容於 3GPP 標準中的隨機程序之時間前置機制改良型隨機存取程序架構(enhanced timing advance based random access procedure, eTARA)。eTARA此改良型架構，利用物聯網裝置定點特性，在傳統隨機存取機制中增加裝置的可辨析性，來提升隨機存取的競爭成功率。同時分散式與集中式決策演算法，來解決多重路徑的誤差影響。此外，改良型架構透過自我放棄機制，減少裝置平均在隨機存取程序中的傳送次數，增加成功機率。本研究透過數學分析與模擬程式，比較時間前置機制傳統架構與改良型架構的表現差異，並驗證實際效益。

This paper considers a narrowband Internet of Things (NB-IoT) system supporting fixed location IoT devices. We proposed an enhanced timing-advance random-access (eTARA) scheme to relieve the congestion of the random-access channels resulted from simultaneous access triggered by massive IoT devices. Each device can utilize the proposed scheme to adjust its admissible timing advance (TA) zone for disabling unnecessary MSG3 retransmission. The collisions can be reduced as result. An analytical model is further presented to estimate the success probability and average access delay of the proposed scheme and optimize the configuration parameters.
