随着WCDMA在全球范围内突飞猛进的进展,以及中国信息产业部组织的WCDMA网络试验的成功开展,WCDMA在中国的推进进程明显加快。由于WCDMA网络对负荷和干扰的敏感性以及WCDMA业务的多样性,使得WCDMA网络规划技术变得更加复杂。结合市场、投资、覆盖、容量、网络规模等各方面因素综合考虑,为满足未来充满激烈竞争和高风险的WCDMA运营战争需要,达到“低成本、快速建网,有效覆盖”的目的,是本文所追求的目标。 本文主要采取全网协调与专题研究相结合的方法,通过一些数据和理论分析进行佐证。本文涉及的专题研究在经验数据、实地勘测、理论计算的基础上,以定量为主的分析中得出定性的结论,提出了与建设相关的建议。 本文进行分析时注重以下几个原则,采取了以下相应措施与方法,以保证研究能遵循科学的方法进行,并能取得一定的理论和实践成果: 业务及话务模型的选择主要参考现阶段天津地区业务及话务模型,结合中国网通集团公司相关原则,考虑WCDMA上马后带来的变数,综合取定。 无线基站站址采用现场勘测方式,携带GPS定位仪、数码相机等必要设备,对各参考站点进行数据采集并记录。 本次无线网络规划采用Aircom仿真软件,运用Monte-carlo仿真法,针对现场勘测选定的站址进行无线网络的静态仿真,通过执行多次用户接入和干扰计算,分析网络运行稳定后的性能结果。 采用CW测试发射机和车载测试方法校正本规划选用的cost231-hata传播模型。 重视PHS对WCDMA的干扰,提出天津网通PHS与WCDMA协调发展的策略。 本论文主要分为以下五章:第一章讲述了本次研究所应用的方法,介绍了国内外WCDMA发展的趋势,界定了本次WCDMA规划的前提条件。第二章分别针对核心网版本选择、覆盖区域、传播模型、链路预算、容量规划、干扰分析、站址设置原则等无线网络规划的主要专题进行了专项研究。第三章在对天津网通发展WCDMA的竞争环境及SWOT分析基础上,确定天津网通WCDMA市场定位、市场及网络发展策略。第四章依据业务预测及业务模型,完成天津网通WCDMA网络规划。第五章从覆盖目标、容量目标、质量目标、成本目标等四个方面说明按照天津网通WCDMA网络规划进行建设后将可以达到的效果。
As WCDMA network is rapidly developing worldwide, together with the successful progress of WCDMA trial network organized by MII of China, WCDMA network deployment is considerably pushed in China. WCDMA network is sensitive to load and interference, and WCDMA applications are multiple, which makes WCDMA network planning technique more complicated. Taking market, investment, coverage, capacity and infrastructure scale into consideration, this article focuses on how to meet the demand of WCDMA operation, which is of high risk and full of intense competition, by realizing“cost-effective and prompt infrastructure deployment and effective coverage”. This article integrates whole-network coordination and special studying, and uses data and theoretical analysis to prove. The special studying comes to qualitative conclusion and puts forward proposals for network construction, based on quantitative analysis using experience data, on-site reconnaissance and theoretical calculation. When making analysis, this article emphasizes the following principles and adopts the following relevant methods to ensure that the studying abides by scientific method and makes some theoretical and practical achievements: Following the rules set by China Netcom, based on current business model and voice-volume model of Tianjin, considering possible changes after deploying WCDMA, this article chooses the business model and voice-volume model after comprehensive calculation. The choice of Base Station is based on on-site reconnaissance, using GPS orientator, digital camera and other necessary appliance to collect and register data of every reference site. Aircom emulation software is adopted in the wireless network planning. Using Monte-carlo emulation method, static emulation is applied in the chosen sites. Through several customer access and interference calculation, analysis is made of network performance after stable operation. The cost231-data transmission mode is revised by using CW test transceiver and truck-carrier test method. This article emphasizes PHS interference in WCDMA and brings forward strategies of balanced development of PHS and WCDMA for Tianjin Netcom. This thesis is divided into 5 chapters. Chapter 1 makes an introduction of the adopted methods and WCDMA development trend home and abroad, and sets the preconditions for the WCDMA planning. Chapter 2 makes special studying on choice of core network version, covering area, transmission model, link budget, capacity planning, interference analysis, and site setting principle etc. Chapter 3 confirms WCDMA market positioning, market and network development strategy for Tianjin Netcom, based on competition environment of WCDMA development and SWOT analysis. Chapter 4 completes the WCDMA network planning for Tianjin Netcom, based on business forecast and business model. Chapter 5 illustrates the effect of Tianjin Netcom WCDMA network planning in the four aspects-coverage, capacity, quality and cost.
