【摘要】：伴隨著移動通信技術(shù)的高速發(fā)展,TD-LTE作為公網(wǎng)4G通信的標(biāo)準(zhǔn),已經(jīng)得到了成熟的大規(guī)模商用,并得到了國家戰(zhàn)略層面的大力支持,而今天無線專網(wǎng)領(lǐng)域卻依然以窄帶數(shù)字集群為主,嚴(yán)重滯后于公網(wǎng)的發(fā)展,目前各個專網(wǎng)廠家已經(jīng)意識到寬帶集群的重要性,無線專網(wǎng)選擇4G已經(jīng)成為行業(yè)的共識。但是由于專網(wǎng)行業(yè)分布特點,特別是中小企業(yè)呈現(xiàn)出局部覆蓋范圍小、上行數(shù)據(jù)流量大、安裝配套環(huán)境惡劣、定制要求多等許多突出問題,傳統(tǒng)的公網(wǎng)LTE廠商的分布式基站設(shè)備直接改造頻率,轉(zhuǎn)變成專網(wǎng)基站已經(jīng)無法滿足中小企業(yè)的需求。針對專網(wǎng)LTE分布式基站的各種弊端,本文提出對一體化LTE宏蜂窩基站的進行相關(guān)研究,改進分布式基站配套要求高、性價比低的問題,在基站結(jié)構(gòu)和可行性方面進行相關(guān)論證和對比,從而證明在中小企業(yè)有一定的實用價值。課題研究內(nèi)容主要有以下三個方面:(1)本文首先對專網(wǎng)行業(yè)進行的發(fā)展進行分析,闡述中小企業(yè)在專網(wǎng)領(lǐng)域的應(yīng)用特點和關(guān)注點,以及國內(nèi)外研究的現(xiàn)狀進行了概述,提出將專網(wǎng)4G基站以小型化、一體化、簡單化,宏蜂窩的架構(gòu)來進行針對性開發(fā),滿足中小企業(yè)的專網(wǎng)需求。(2)然后,對一體化TD-LTE宏蜂窩基站的架構(gòu)從硬件、軟件和OMC網(wǎng)管三個方面的處理流程框架進行研究,論證項目的可行性。(3)最后,針對專網(wǎng)行業(yè)中典型的應(yīng)用-駕駛員科目三考試,從網(wǎng)絡(luò)設(shè)計、工程施工、數(shù)據(jù)測試方面驗證了本系統(tǒng)的有效性和可行性,測試結(jié)果證明,系統(tǒng)滿足了中小企業(yè)客戶的實際需求,同時具有很強的實用價值和商業(yè)價值。
[Abstract]:With the rapid development of mobile communication technology, TD-LTE as the public network 4G communication standard, has been mature large-scale commercial, and has been vigorously supported by the national strategic level. Today, however, the wireless private network is still dominated by narrowband digital trunking, which lags behind the development of public network seriously. At present, the manufacturers of private networks have realized the importance of broadband trunking. The choice of 4G in wireless private network has become the consensus of the industry. However, due to the characteristics of private network industry distribution, especially the small and medium-sized enterprises show a small local coverage, the uplink data flow is large, and the installation and supporting environment is bad. There are many outstanding problems, such as customization requirements, and so on. Traditional LTE manufacturers directly transform the frequency of distributed base station equipment into private network base station can no longer meet the needs of small and medium-sized enterprises. In view of the disadvantages of private network LTE distributed base station, This paper puts forward the related research of integrated LTE macrocellular base station, and improves the problem of high matching requirement and low performance-price ratio of distributed base station, and demonstrates and compares the structure and feasibility of the base station. This paper first analyzes the development of the private network industry, expounds the characteristics and concerns of the application of small and medium-sized enterprises in the field of private network. And the current situation of domestic and foreign research is summarized. It is proposed that the 4G base station of the private network should be developed by miniaturization, integration, simplification and macrocellular architecture to meet the special network demand of small and medium-sized enterprises. This paper studies the architecture of integrated TD-LTE macrocellular base station from three aspects of hardware, software and OMC network management, and proves the feasibility of the project. Finally, aiming at the typical application-driver subject three examination in the special network industry, The effectiveness and feasibility of the system are verified from the aspects of network design, engineering construction and data testing. The test results show that the system meets the actual needs of small and medium-sized enterprises, and has strong practical and commercial value.
