【摘要】：Femto系統(tǒng)是毫微微米級的蜂窩小基站系統(tǒng)。Femto系統(tǒng)采用IP網(wǎng)絡(luò)作為其回程網(wǎng)絡(luò),為小區(qū)域范圍的用戶提供移動通信業(yè)務(wù),由此推動了移動業(yè)務(wù)和有線寬帶業(yè)務(wù)的融合。Femto系統(tǒng)成本低、服務(wù)質(zhì)量高、易安裝,十分適合部署在室內(nèi)環(huán)境中,尤其適用于礦井、隧道等地下環(huán)境部署專屬移動通信網(wǎng)絡(luò)。隨著Femto技術(shù)的發(fā)展,Femto系統(tǒng)僅支持業(yè)務(wù)在單一接入模式中的漫游,不支持在不同接入模式中的融合漫游,這為利用Femto系統(tǒng)部署移動通信網(wǎng)絡(luò)帶來了很大的不便。特別是在室內(nèi)、礦井、隧道等環(huán)境中部署移動通信網(wǎng)絡(luò)時,需要重復(fù)建設(shè)大量獨立的Femto相關(guān)設(shè)備,這不僅增加了建設(shè)成本,還會導(dǎo)致部署在這些環(huán)境中的移動通信網(wǎng)的網(wǎng)絡(luò)程度過于復(fù)雜。與此同時,當(dāng)在不同接入技術(shù)的Femto系統(tǒng)的核心網(wǎng)中進行消息交互時,消息頻繁地在不同核心網(wǎng)間切換還會增加移動通信網(wǎng)絡(luò)的維護成本。目前,現(xiàn)有的有關(guān)Femto技術(shù)的研究僅局限于研究單一接入模式,設(shè)計并實現(xiàn)的Femto系統(tǒng)也僅支持單一接入技術(shù)。但是面對存在多種接入技術(shù)的復(fù)雜通信環(huán)境,沒有對可支持多接入模式的Femto技術(shù)進行研究。本文針對上述問題,在單一接入模式的Femto系統(tǒng)的基礎(chǔ)上研究了一種多模融合移動通信Femto網(wǎng)關(guān)技術(shù)。論文首先綜述了 Femto技術(shù)的國內(nèi)外研究現(xiàn)狀,研究了 GSM Femto系統(tǒng)、TD-SCDMA Femto系統(tǒng)以及LTE Femto系統(tǒng)的工作原理。本文提出了一種多模融合移動通信Femto網(wǎng)關(guān)技術(shù)方案,并設(shè)計了六大功能模塊,包括數(shù)據(jù)模塊、網(wǎng)關(guān)與基站間接口模塊、網(wǎng)關(guān)與核心網(wǎng)之間接口的控制面和用戶面的融合模塊、應(yīng)用管理模塊以及協(xié)議轉(zhuǎn)換模塊。根據(jù)技術(shù)方案設(shè)計并概述了融合網(wǎng)關(guān)的工作流程和應(yīng)用場景的信令流程。本文對部分功能模塊的軟件結(jié)構(gòu)進行了設(shè)計和實現(xiàn),最終在Linux 2.6.32內(nèi)核平臺上實現(xiàn)了本文所設(shè)計的融合網(wǎng)關(guān),并對本文負(fù)責(zé)實現(xiàn)的功能模塊進行了功能測試,在應(yīng)用場景中對融合網(wǎng)關(guān)進行了驗證性功能測試。通過本文所研究的融合網(wǎng)關(guān)技術(shù),可以有效解決室內(nèi)移動通信網(wǎng)絡(luò)建設(shè)成本和維護成本過高的問題,可以降低室內(nèi)移動通信網(wǎng)絡(luò)的復(fù)雜度,增加Femto設(shè)備的復(fù)用程度。
[Abstract]:Femto system is a small cellular base station system. Femto system uses IP network as its backhaul network to provide mobile communication services for users in a small area. This promotes the integration of mobile services and wideband services. Femto system has low cost, high quality of service, easy to install, and is very suitable for deployment in indoor environment, especially in mines. With the development of Femto technology, Femto system only supports roaming in a single access mode. Does not support the fusion roaming in different access modes, which brings great inconvenience to the deployment of mobile communication network using Femto system, especially in indoor, mine. When deploying mobile communication networks in tunnels and other environments, it is necessary to repeatedly build a large number of independent Femto related equipment, which not only increases the cost of construction. It can also lead to the complexity of the mobile communication network deployed in these environments. At the same time, when the core network of Femto systems with different access technologies is exchanged. The frequent handoff of message between different core networks will also increase the maintenance cost of mobile communication networks. At present, the existing research on Femto technology is limited to the study of single access mode. The Femto system designed and implemented only supports single access technology, but in the face of complex communication environment with multiple access technologies. There is no research on Femto technology which can support multi-access mode. On the basis of Femto system with single access mode, this paper studies a multi-mode fusion mobile communication Femto gateway technology. Firstly, this paper summarizes the domestic and foreign research status of Femto technology. The GSM Femto system is studied. The working principle of TD-SCDMA Femto system and LTE Femto system. This paper presents a multi-mode fusion mobile communication Femto gateway. Six functional modules are designed, including data module, interface module between gateway and base station, interface control surface and user interface module between gateway and core network. Application management module and protocol conversion module. According to the technical scheme design and outline the workflow of the gateway and the signaling process of the application scenario. This paper designs and implements the software structure of some functional modules. Finally, the fusion gateway is implemented on the Linux 2.6.32 kernel platform, and the functional modules are tested. Through the fusion gateway technology studied in this paper, it can effectively solve the problem of high construction cost and maintenance cost of indoor mobile communication network. It can reduce the complexity of indoor mobile communication network and increase the reuse degree of Femto devices.
