【正文】 antenna height and angle, the adjacent Node B position and the pilot signal, the adjacent Node B pilot search window size, trigger switch threshold value. In the process of work optimization, we need to use different tools, and these tools have different effects. 1 planning software In detail simulation process, we will be new or expansion, upgrading the site information input to the electronic map. Through repeated simulation and tuning, resulting in some constraints ( such as site location, determining fixed configuration ), optimal coverage, capacity, quality of service indicators. Land use planning software optimization stage, through the simulation to determine the system factors include: Node B site, type of antenna, antenna angle. On the basis of the existing work expansion, upgrade, the operator is always concerned with optimization is pleted, the new capacity can achieve the simulation predicted value. 2 work management system Network management system is to monitor work performance, the system data acquisition. It can be shown that the distribution business, the business such as the quality of call loss rate statistics, therefore, can help the maintenance engineer for fault location. QoS indexes are relatively flexible, according to KPI requirements or cost control requirements, can be identified in the corresponding QoS index. The constraints include: hardware resources ( channel capacity configuration ), software resources ( interference caps ), call loss rate, dropped call rate, call rate, handover success rate, the uplink / downlink channel load, data retransmission / delay, data and circuit type business rate etc.. To meet these requirements, work management system should have the following 3 functions: ( 1) monitoring work traffic and performance。 Real time load analysis and control。 3G work optimization 摘自 TDSCDMA 無線網(wǎng)絡(luò)優(yōu)化原理及方法 One, the basic process of 3G work optimization Operators aim is to build a profitable work, they are very concerned about the work construction, expansion and upgrade in the process of investment cost and its final performance, but the expansion, upgrade costs and work performance is a pair of contradiction. Construction cost budget and control can get relatively accurate numerical, but the performance of the work is posed of many subjective and objective factors. On one hand, the work capacity expansion, upgrading and upgrades to existing users can guarantee the normal use, on the other hand, it also can provide petitive new business, and makes further expansion, upgrading and upgrades can be carried out smoothly. In this way, the work optimization bees a longterm, iterative process. Network optimization should be able to according to the operator39。 畢 業(yè) 設(shè) 計(jì)（論 文） 外 文 參 考 資 料 及 譯 文 譯文題目： TDSCDMA 與 WCMA 網(wǎng)絡(luò)優(yōu)化分析 3G work optimization 學(xué)生姓名： 學(xué) 號： 專 業(yè)： 通信工程 所在學(xué)院： 龍?bào)磳W(xué)院 指導(dǎo)教師： 職 稱： 講師 2021 年 12 月 1 日 說明： 要求學(xué)生結(jié)合畢業(yè)設(shè)計(jì)（論文）課題參閱一篇以上的外文資料，并翻譯至少一萬印刷符（或譯出 3 千漢字）以上的譯文。 譯文原則上要求打印（如手寫，一律用 400 字方格稿紙書寫），連同學(xué)校提供的統(tǒng)一封面及英文原文裝訂，于畢業(yè)設(shè)計(jì)（論文）工作開始后 2 周內(nèi)完成，作為成績考核 的一部分。s specific needs by means of software tool automatically, can also through manual intervention to achieve the capacity, coverage, QoS ensure a balance point. 3G work system structure is shown in figure 1. Generally, work and includes 3 levels: On Node B, the mobile station performance indicators for realtime calculation and simulation, including fast power control, rapid congestion resolved, wireless link adaptive, channel allocation。 Based on experience or statistical results, through roadshow, work optimization software for work performance prediction. In front of 2 levels, in the work is pleted, by the work management system through the online monitoring and statistics in real time automatic adjustment, while the third level is the need for professionals to carry out, also is we often say that the work optimization. Artificial work optimization can be divided into the following several steps: First of all, the operator should be based on their own characteristics the definition of a good work optimization is pleted to achieve t
