【摘要】：随着3G网络的不断发展,娄底联通WCDMA网络存在农村广覆盖差;城市深度覆盖较差的问题,造成部分用户尤其是高层住宅小区用户感知不佳。多年来娄底联通采用的大规模地建设宏基站的规划方式,存在成本耗费巨大,施工工期长等问题,远远无法满足当前网络发展的需求。通过新的规划方法,使用新技术、新产品灵活组网,分场景、快速、低成本地解决网络问题,提升网络质量。本文通过大量的DT测试、CQT测试、MR数据分析、投诉数据分析,研究了娄底WCDMA网络存在的主要问题,实现了2014年WCDMA精品网络的明确目标,完成覆盖目标的方法。不同于传统简单粗暴地大量建设宏基站的方法,本文通过分场景使用不同的规划方法实现经济有效地解决覆盖问题:市区县城以RRU拉远、微基站和美化天线结合;农村区域采用2T4R的设备、特型天线和导频功率调整实现对人口的有效覆盖;居民小区室内外协同覆盖,通过扇区高低层覆盖、室分信号外引、新增四五六小区等手段,实现基站小区级精准覆盖,严控站高、站距;校园网络更多地考虑容量规划;同时通过微基站、FEMTO新产品解决特殊场景的网络覆盖问题等。通过采取分场景地规划RRU拉远、微基站等方式,实现了娄底联通2014年建设降本增效,相比传统方式,整体建设成本仅为规划宏基站的1/3,组网更加迅速,工程完工比往年进度快2个月,乡镇网络整体覆盖水平由54.05%上升到62.2%,3G用户网络质量投诉率下降了20%。最后,本文通过娄底联通FDD-LTE初期规划建设情况,提出了以3、4G协调发展,WCDMA为基础承载网、FDD-LTE网络实现热点有价值区域连续覆盖的发展规划。这对未来娄底联通无线网络发展带来深远的影响。
[Abstract]:With the continuous development of 3G network, Loudi Unicom WCDMA network has the problem of poor rural coverage and poor urban depth coverage. This has caused some users, especially those in high-rise residential areas, to perceive poorly. The planning method adopted by Loudi Unicom for large-scale construction of Acer Station for many years has many problems, such as huge cost, long construction period, and so on. Far from meeting the needs of the current network development. Through new planning methods, using new technologies, new products flexible networking, sub-scenario, fast, low-cost solutions to network problems, This paper studies the main problems existing in Loudi WCDMA network through the analysis of Mr data and complaint data, and realizes the definite goal of WCDMA fine network in 2014. Different from the traditional method of building Acer station in large numbers, this paper solves the coverage problem economically and effectively by using different planning methods in different scenarios: the county town in the urban area is pulled away by RRU. The combination of microbase station and beautification antenna; rural area using 2T4R equipment, special antenna and pilot power adjustment to achieve effective coverage of the population; Add 456 community and other means to achieve the base station cell level accurate coverage, strict control of the station, station distance, campus network more consideration of capacity planning; At the same time, the new products of FEMTO are used to solve the network coverage problem of special scenarios. By adopting the methods of sub-scenario planning RRU remote, micro-base station and so on, Loudi Unicom has realized the construction of reducing cost and increasing efficiency in 2014, compared with the traditional way. The overall construction cost is only 1 / 3 of the planning of Acer Station, and the construction of the network is more rapid. The completion of the project is two months faster than in previous years. The overall coverage level of the township network has risen from 54.05% to 62.2% of the total number of complaints about the quality of the 3G user network. Finally, the rate of complaints about the quality of the 3G user network has dropped by 20%. Through the initial planning and construction of Loudi Unicom FDD-LTE, Based on the coordinated development of 3G and WCDMA, the FDD-LTE network is proposed to realize the continuous coverage of hot spots and valuable areas, which will have a profound impact on the future development of Loudi Unicom wireless network.
