【摘要】：隨著移動(dòng)通信的普及,建筑物內(nèi)的話務(wù)密度不斷上升,室內(nèi)的話務(wù)占總話務(wù)的比例越來越高。根據(jù)國(guó)外運(yùn)營(yíng)商的統(tǒng)計(jì),70%以上的話務(wù)量來自室內(nèi),且數(shù)據(jù)業(yè)務(wù)絕大多數(shù)發(fā)生在室內(nèi),而室內(nèi)恰恰是網(wǎng)絡(luò)覆蓋的薄弱環(huán)節(jié)。室內(nèi)分布系統(tǒng)是針對(duì)室內(nèi)用戶群,用于改善建筑物內(nèi)移動(dòng)通信環(huán)境的一種覆蓋方式,其原理是利用室內(nèi)天線分布系統(tǒng)將移動(dòng)基站的信號(hào)均勻分布在室內(nèi)每個(gè)角落,從而保證室內(nèi)區(qū)域擁有理想的信號(hào)覆蓋。室內(nèi)分布系統(tǒng)可以較為全面的改善樓宇內(nèi)的通話質(zhì)量,提高接通率,同時(shí)可以分擔(dān)宏蜂窩話務(wù),擴(kuò)大網(wǎng)絡(luò)容量,從整體上提高移動(dòng)網(wǎng)絡(luò)的服務(wù)水平,因此室內(nèi)網(wǎng)絡(luò)質(zhì)量的好壞也成為用戶選擇運(yùn)營(yíng)商參考的標(biāo)準(zhǔn)。鑒于此情況,室內(nèi)分布系統(tǒng)項(xiàng)目的優(yōu)化工作也越來越受到運(yùn)營(yíng)商的重視。本文依據(jù)南京聯(lián)通室分優(yōu)化項(xiàng)目,結(jié)合南京聯(lián)通WCDMA、GSM網(wǎng)絡(luò)優(yōu)化、細(xì)化測(cè)試規(guī)范和報(bào)告要求,應(yīng)用項(xiàng)目管理理論分階段明確了南京聯(lián)通室內(nèi)分布系統(tǒng)項(xiàng)目?jī)?yōu)化重點(diǎn)和關(guān)鍵點(diǎn),對(duì)室內(nèi)覆蓋WCDMA、GSM系統(tǒng)的硬件和參數(shù)進(jìn)行了優(yōu)化,對(duì)室內(nèi)覆蓋WCDMA、GSM信號(hào)的效果進(jìn)行了后評(píng)估。通過優(yōu)化項(xiàng)目后評(píng)估,全面提升了南京聯(lián)通樓宇內(nèi)移動(dòng)網(wǎng)絡(luò)質(zhì)量,優(yōu)化了室分覆蓋的樓宇,提高了室內(nèi)信號(hào)覆蓋水平和室內(nèi)網(wǎng)絡(luò)質(zhì)量和數(shù)據(jù)業(yè)務(wù)速率,滿足了室內(nèi)用戶對(duì)語音及數(shù)據(jù)業(yè)務(wù)的要求,提升了用戶體驗(yàn);同時(shí)對(duì)無室分覆蓋的樓宇進(jìn)行網(wǎng)絡(luò)摸底,收集經(jīng)緯度信息和標(biāo)準(zhǔn)7級(jí)地址,最終形成了南京樓宇移動(dòng)網(wǎng)信息GIS數(shù)據(jù)庫(kù),為后期南京聯(lián)通網(wǎng)絡(luò)建設(shè)提供了依據(jù)。
[Abstract]:With the popularity of mobile communication, the traffic density in buildings is increasing, and the proportion of indoor traffic to total traffic is increasing. According to the statistics of foreign operators, more than 70% of the traffic comes from indoor, and most of the data services take place indoors, and indoor is the weak link of network coverage. The indoor distribution system is a kind of coverage method for the indoor user group, which is used to improve the mobile communication environment in the building. Its principle is to distribute the signals of the mobile base station evenly in every corner of the room by using the indoor antenna distribution system. In order to ensure that the indoor area has an ideal signal coverage. The indoor distribution system can comprehensively improve the quality of communication in the building and increase the connection rate. At the same time, it can share the macro cellular traffic, expand the network capacity, and improve the service level of the mobile network as a whole. Therefore, the quality of indoor network has become the standard for users to select operators. In view of this situation, the optimization of indoor distribution system project is paid more and more attention by operators. According to the project of Nanjing Unicom's room division optimization and the optimization of Nanjing Unicom's WCDMA GSM network, this paper clarifies the key points and key points of Nanjing Unicom's indoor distribution system project optimization by stages by using project management theory. The hardware and parameters of indoor coverage WCDMA-GSM system are optimized, and the effect of indoor coverage WCDMA-GSM signal is evaluated. Through the post-evaluation of the optimization project, the mobile network quality in Nanjing Unicom building is comprehensively improved, the building with room coverage is optimized, and the indoor signal coverage level, indoor network quality and data service rate are improved. It meets the requirements of indoor users for voice and data services, and improves the user experience. At the same time, it carries out network mapping of buildings without room coverage, collects longitude and latitude information and standard 7 level addresses. Finally, the information GIS database of Nanjing Building Mobile Network is formed, which provides the basis for the later construction of Nanjing Unicom Network.
