【摘要】：近年來，隨著移動通信的飛速發(fā)展，手機已經(jīng)逐漸成為一種現(xiàn)代通訊工具廣泛應(yīng)用于人民群眾的日常生活，大多數(shù)的手機用戶不是僅僅滿足于良好的戶外移動通信服務(wù)�，F(xiàn)在多數(shù)建筑為采用高密材料且面積在數(shù)萬平米以上的封閉式建筑，由于室內(nèi)布局的復(fù)雜性，不利于傳統(tǒng)宏站的深度覆蓋，致使室內(nèi)覆蓋度不足，影響用戶的業(yè)務(wù)感知。隨著用戶對網(wǎng)絡(luò)質(zhì)量關(guān)注度的不斷提高，解決室內(nèi)覆蓋的問題已經(jīng)箭在弦上。 針對室內(nèi)覆蓋的難題，發(fā)展建設(shè)室內(nèi)分布是解決該問題的重要途徑。與傳統(tǒng)宏站結(jié)構(gòu)相比，室內(nèi)覆蓋由信號源和室內(nèi)分布系統(tǒng)兩大部分組成。室內(nèi)分布系統(tǒng)可以直接有效的作用于建筑物內(nèi)部，，減少墻體的穿透損耗，能夠更為全面的改善室內(nèi)信號覆蓋強度，提升室內(nèi)通話質(zhì)量，并通過話務(wù)下次擴大網(wǎng)絡(luò)容量，緩解宏站的網(wǎng)絡(luò)負荷。 作者主要從室內(nèi)覆蓋系統(tǒng)設(shè)計預(yù)評估、現(xiàn)網(wǎng)室分系統(tǒng)的優(yōu)化等方面入手，介紹了室分系統(tǒng)的網(wǎng)絡(luò)架構(gòu)、發(fā)展趨勢，并通過結(jié)合工作案例，從系統(tǒng)性能、覆蓋能力、優(yōu)化標(biāo)準(zhǔn)對各方面進行了系統(tǒng)的研究和分析，總結(jié)了室內(nèi)覆蓋系統(tǒng)的優(yōu)化原則和室內(nèi)覆蓋系統(tǒng)的設(shè)計方案，研究了基于RRU新技術(shù)應(yīng)用的室內(nèi)覆蓋系統(tǒng)與傳統(tǒng)室內(nèi)覆蓋系統(tǒng)方案的優(yōu)缺點，并通過在吉大一院的實際應(yīng)用對比，驗證了RRU技術(shù)方案的可行性及各種優(yōu)點，論文最后根據(jù)理論分析，提出了分場景的RRU室內(nèi)覆蓋系統(tǒng)的方案建議。
[Abstract]:In recent years, with the rapid development of mobile communication, mobile phone has gradually become a modern communication tool widely used in the daily life of the people. Most mobile phone users are not only satisfied with good outdoor mobile communication service. At present, most buildings are closed buildings with high density materials and area of tens of thousands square meters. Because of the complexity of indoor layout, it is not conducive to the depth coverage of traditional macro stations, resulting in insufficient indoor coverage and affecting users' perception of business. With the increasing attention of users to network quality, the problem of indoor coverage has been solved. In view of the difficult problem of indoor coverage, the development and construction of indoor distribution is an important way to solve this problem. Compared with the traditional macro station structure, indoor coverage consists of two parts: signal source and indoor distribution system. The indoor distribution system can directly and effectively act on the interior of the building, reduce the penetration loss of the wall, improve the indoor signal coverage intensity, improve the quality of indoor communication, and expand the network capacity next time through telephone traffic. Relieves the network load of macro station. From the aspects of pre-evaluation of indoor coverage system design and optimization of current network room subsystem, the author introduces the network structure and development trend of room sub-system, and through the combination of work cases, from the system performance, coverage capacity, and so on, the author introduces the network structure and development trend of room sub-system. The optimization standard has carried on the systematic research and the analysis to each aspect, has summarized the indoor cover system optimization principle and the indoor cover system design plan, has carried on the systematic research and the analysis to the indoor coverage system. This paper studies the advantages and disadvantages of the indoor coverage system based on the new RRU technology and the traditional indoor coverage system, and verifies the feasibility and various advantages of the RRU technical scheme through the comparison of its practical application in the first Hospital of Jilin University. Finally, according to the theoretical analysis, the proposal of scenario-based RRU indoor coverage system is proposed.
