RUA通訊協定之設計與實作

Abstract

Femtocell 被視為延伸行動通訊網路覆蓋範圍、提昇系統容量的方法。3GPP 制定整合家用無線基地台(Home Node B) 與戶外無線基地台(Node B) 的 Femtocell 網路架構。本論文敘述Femtocell 網路架構和相關的Iuh 介面通訊協 定(如：RANAP, SCTP 等)。在Femtocell 網路架構中，RANAP User Adpatation (RUA) 提供一個負擔較小的機制來傳輸家用無線基地台與家用無線基地台閘道 (HNB-Gateway) 之間的控制功能與RANAP 訊息。我們並說明RUA 如何與其他通訊 協定互動。本研究介紹在Femtocell/HNB 專案中採用訊息佇列設計與實作的RUA 通訊協定。我們設計的RUA 經由訊息佇列與一致性的基本流程模型(unified primitive flow model) 可以在不同的系統與平台上運作。

Femtocell is proposed extend the mobile network coverage in environments such as deep building and to enhance the system capacity. 3GPP has proposed Femtocell Network Architecture (FNA) to integrate Home Node B (HNB) and Node B. In this paper, we describe 3GPP FNA and related Iuh interface protocols (e.g., RANAP, SCTP, etc.). Specifically, we will focus on RANAP User Adaptation (RUA) in FNA, which is a lightweight mechanism to transport RANAP messages and control functions between HNBs and HNB-Gateways. We also illustrate how RUA interworks with other FNA protocols. This study describes our design and implement of RUA protocol in a Femtocell/HNB project through Message Queuing (MQ) method. Based on our design, the RUA protocol can work on different operating systems and platforms by the MQ method and the unified primitives.
