TD-SCDMA无线覆盖的相关问题研究
摘要
TD-SCDMA作为我国首次提出的国际移动通信标准,在物理层核心技术上拥有自主知识产权,填补了移动通信制式国产化的空白,并在由中国移动推动下已经走过了4个年头。在这四期工程中技术在不断演进,设备在更新换代,经验在不断增加。
在本论文中,结合作者在中国移动4期TD-SCDMA项目中的经验,对无线宏基站的勘察与设计方面的天线选型,天线安装方式,天线的挂高、方向角、下倾角等工程参数的不同场景的取值,天线之间隔离度的要求,BBU、RRU、GPS、线缆、机房、站点的安装选择要求等提出了一些要求。并针对TD-SCDMA网络实际案例进行分析,得出建设网络中的注意事项和优化调整的方法。在室内分布系统方面,我们采用等效节点法和功率预确定法来进行功率的预算。明确了主题设计思路,统一了设计方法,使得室内分布系统的设计方案在GSM、TD-SCDMA、WLAN多系统合路方面具备兼容性强、排障速度快、优化调整简单等众多优点。
The third generation mobile communication system TD-SCDMA is our first proposed by the international mobile communication standard, in the physical layer of the core technology with independent intellectual property rights. From 1998, China formally to the International Telecommunication Union proposed TD-SCDMA technology standards, after 10 years of efforts, China's TD-SCDMA technology has made breakthrough progress, system performance is greatly improved, system equipment with the scale of business networking capability, many companies in the industrial competition pattern has been formed. In 2009 January 7 day letter department issued China's third generation of mobile communication business licence, China Mobile Communications Corporation Based on the TD-SCDMA standard of the third generation mobile communication licenses. China Mobile was launched in April 2007 TD network construction, because at that time the network is in construction initial stage, smaller, only 8 Olympic City, the total lack of billions of first-round tender. Then in 2008 November and the end of the TD two project of China Mobile investment exceeds 30000000000, covering the city extended to the whole country 28 city and region. China mobile phase three covers 200 City, construction of base station 39000, a total investment of 55800000000 yuan. TD four period construction base station 102000, in addition to the first three of the 238 city TD network optimization and fill point, but in 101 a new TD network.
China Mobile shoulder our country with independent intellectual property rights of the 3G standard -- TD-SCDMA construction operation tasks. In the face of glorious and arduous history mission, China Mobile in the relevant government departments under the guidance of support, confidence, overcome difficulties, put one's heart and soul into, make every attempt to carry out a comprehensive development of TD-SCDMA, TD-SCDMA building, completed construction of TD-SCDMA network three phase of the project, for the realization of TD-SCDMA commercial success lay a solid foundation.
In order to meet the business needs and the needs of market competition, China Mobile to honor society and industry commitment, promote TD industry development, China Mobile puts forward to realize" three years plan, completed two years " construction target, in 2010 the expansion project is completed, China Mobile TD base station number 220000, including Acer station 125000, indoor distributed base station carrier frequency of 95000, reached number 1680000. Connection rate, call drop rate and network quality indicators have been close to the 2G level of KPI.
China Mobile 3G ( TD-SCDMA ) network 2011 capacity expansion project will achieve all prefecture-level cities, county-level city and county the city zone coverage, while covering the administrative regional sustainable development network expansion and optimization supplementary point, continue to adhere to the " two 100% " the construction principle, and further improve the network coverage. In the business of regional hot spots, TD network coverage and quality with China Unicom, China Telecom 3G network in market competition ability.
This combination of China Mobile Group internal guiding principles, manufacturers of equipment parameters, 4 TD project experience in antenna, the antenna installation, height of antenna, direction angle, tilt and other engineering parameters, between the antenna isolation requirements, BBU, RRU, GPS, cable, computer room, site selection and installation requirements made on some problems, put forward some requirements. In the indoor distribution system, we use the equivalent node method and the power determines the method to carry out the power budget. The theme of the design train of thought, unified design method, makes the indoor distribution system design in GSM, TD-SCDMA, WLAN system combined with strong compatibility, troubleshooting, speed, optimization and adjustment has many advantages such as simple.
In this paper, combined with the author of China Mobile in 4 TD-SCDMA project experience in the macro base station, wireless network survey, design, planning, optimization and indoor distribution system of survey and design, principle, discusses the transformation scheme. Acer station in the first user equipment UE, NodeB wireless base station, base station controller RNC and network standard interface Iub, Iur, Iu and Uu introduced the wireless network composition and each part of the main function. In the wireless network design indicators introduced AMR voice business, CS64kbps video and PS 64Kbps, PS 128kbps, PS 384kbps data services carrying business objectives, in service quality indicator is introduced the mobile station in the wireless coverage area can pass rate, wireless channel call loss, block error rate target value, the index requirements introduced the TD wireless network PCCPCH RSCP, PCCPCH C / I. On the macro base station and wireless BBU+RRU solutions, antenna, in Bobbi, while the number and ratio of the antenna installation, illustrated. In the project put forward reasonable parameters of antenna height, the position of the antenna should meet the sector antenna and different systems of isolation between antennas requirements, antenna downdip problems. And in the RRU position requirements, GPS antenna location requirements, cable laying, room requirements and site selection aspects. Put forward urban and rural areas, highway, hotspots, ultra distance covered areas such as different scenario solution. Acer station proposed in wireless network planning planning, the planning time slot code, frequency planning, neighborhood planning and PCCPCH, FPACH, DWPCH power set. In wireless network optimization is proposed to optimize the problem in hanging high, direction angle, tilt angle of problem of engineering parameter problems and solutions. In blind weak coverage, overburden, neighboring clutter and other aspects of analysis put forward to solve the method. In the indoor distribution system is clearly with the small power, the principle of multiple antenna indoor distribution system builds overall train of thought. Indoor distribution system, and puts forward the new transformation, direct path such as way of requirements. In order to power determines the method and equivalent node method for indoor distribution system power budget and antenna placed and theoretical basis. Through analyzing the design scheme and the actual measured value of research to develop the chamber system omnidirectional and directional antennas use principle, a flat layer of window area, flat layer of window area, elevators, underground parking and other power of predetermined values. In according to the indoor propagation model inverted roll distance between antenna, antenna position. Then according to the different coverage areas by tuning the antenna port power and antenna position to meet the requirements of the goal of indoor distribution system. The flat layer antenna group input equivalent to a 1 node, a flat layer of input equivalent to 1 nodes, multiple input equivalent to 1 nodes, according to the routing and community settings to determine the final all antenna connection diagram. Further elaborates the cooperation way, passive device transformation principle, and antenna feeder retrofit scheme. To elucidate the frequency allocation, switching, signal leakage problems, combining interference, noise and other issues. Proposed indoor distributed system signal leakage problems, ping-pong switching problems causes and solutions, as well as the elevator weak coverage problem solving.
