【摘要】：隨著城市化進程的不斷加快,室內(nèi)弱覆蓋問題日益突出。一方面室分投資遠遠無法滿足室內(nèi)弱覆蓋需求,另一方面部分居民小區(qū)等特定場所新建的宏站和室分被拆除的風險比較大,存在投資浪費的現(xiàn)象。因此,必須改變主要依靠新建室分解決室內(nèi)弱覆蓋的傳統(tǒng)建設思路,尋找一種低成本、低風險且快速有效的建設方式。本文則針對室內(nèi)區(qū)域網(wǎng)絡弱覆蓋的問題,尤其是企業(yè)等辦公區(qū)域的網(wǎng)絡優(yōu)化,提出了基于FemtoAP的解決方案。首先針對高層室內(nèi)覆蓋問題,討論了室內(nèi)分布式系統(tǒng)、WLAN及Femto等三種技術方案,并從組網(wǎng)方式、成本及用戶體驗等方面進行了對比分析。由分析可知,Femto技術在面向小規(guī)模區(qū)域或集團、家庭客戶,尤其是對容量需求小、重要的弱覆蓋區(qū)或覆蓋盲區(qū)具有較好的作用。其次通過對中國移動目前的TD制式(TD-SCDMA. TD-LTE)的網(wǎng)絡結構和關鍵技術的分析,討論了在中國移動網(wǎng)絡下Femto的網(wǎng)絡結構和及其關鍵技術。接著面臨當前集團內(nèi)用戶對網(wǎng)絡覆蓋優(yōu)化的需求日益迫切的局面之下,在給出了Femto企業(yè)應用方案,可以依托不同場景內(nèi)的IP寬帶接入,完全利用現(xiàn)有的寬帶資源,同時為用戶提供TD-SCDMA和WLAN接入信號。結合江蘇移動制定的關于企業(yè)級Femto的設計規(guī)范,詳細的介紹了安裝條件、安裝方式以及設計目標,并且重點針對寫字樓、賓館酒店、商業(yè)建筑等三種場景給出了方案設計細則。最后按照辦公區(qū)和小區(qū)的場景給出了企業(yè)級Femto AP的測試情況,通過測試得出Femto對于網(wǎng)絡優(yōu)化的較好作用。
[Abstract]:With the development of urbanization, the problem of weak indoor coverage is becoming more and more prominent. On the one hand, the indoor investment is far from meeting the demand of weak indoor coverage, on the other hand, the risk of the demolition of the new macro stations and rooms in some residential areas and other special places is relatively high, and there is a phenomenon of investment waste. Therefore, it is necessary to change the traditional construction thought which mainly depends on the new building room to solve the weak indoor coverage, and to find a low cost, low risk and fast and effective construction method. In this paper, a solution based on FemtoAP is proposed to solve the problem of weak coverage of indoor area network, especially the optimization of office area. In this paper, three technical schemes of indoor distributed system, WLAN and Femto, are discussed firstly, and the comparison and analysis are carried out from the aspects of networking mode, cost and user experience. From the analysis, we can see that Femto technology plays a better role in small scale area or group, home customer, especially in weak coverage area or blind area with small capacity demand. Secondly, TD-SCDMA-TD-SCDMA-TD-SCDMA-TD-SCDMAthrough the current TD system of China Mobile. The network structure and key technologies of Femto in China Mobile Network are discussed. Then in the face of the increasingly urgent demand for network coverage optimization by users in the group, Femto enterprise application scheme is given, which can rely on IP broadband access in different scenarios and make full use of existing broadband resources. At the same time, TD-SCDMA and WLAN access signals are provided to users. Combined with the design specification of enterprise Femto made by Jiangsu Mobile, the installation conditions, installation methods and design objectives are introduced in detail, and the detailed design rules are given for three kinds of scenes, namely office buildings, hotels and hotels, and commercial buildings. Finally, according to the scene of office area and residential area, the test of enterprise Femto AP is given, and the result shows that Femto plays a better role in network optimization.
