摘要(中) 本篇論文主要目的在縮短控制端流程的時間,以達到縮短資料服
務延遲的時間。由於目前LTE 網路中的控制端流程都是循序漸進的
完成,然而並不是所有的控制訊息對於開始資料服務都是必要的。我
們透過繞過這些步驟,或是將流程管線化已達到縮短控制端流程的時
間,以縮短資料服務的延遲。
摘要(英) This paper aims to reduce the data service latency by reducing the control
plane procedure. In LTE, the control plane operations run sequentially
which cause high data service latency. However, not all control operations
are needed for starting the data service. We bypass or pipeline these steps
to speed up the control plane procedure. Then the data service can be ready
sooner.
