【摘要】：TD-SCDMA系統(tǒng)是由中國第一個提出的、具有自主知識產(chǎn)權(quán)的第三代移動通信系統(tǒng)。根據(jù)中國移動公布的2012年前三季度主要運營數(shù)據(jù),截至2012年9月30日,中國移動TD-SCDMA用戶數(shù)達7560萬戶,占中國3G市場的37%。從2007年開始試商用至今,TD-SCDMA已經(jīng)進行到了第五期工程建設(shè),截至2012年4月底,中國移動部署的TD-SCDMA基站已經(jīng)達到了22.8萬個,并且計劃到2014年實現(xiàn)40萬個基站部署。在用戶數(shù)和各項業(yè)務量快速增長的同時,網(wǎng)絡(luò)容量和質(zhì)量問題變得越來越突出,而這些問題的解決很大程度上要依賴于網(wǎng)絡(luò)合理而有效的頻率及擾碼規(guī)劃。 本文基于實驗室的TD-SCDMA系統(tǒng)擾碼規(guī)劃研究項目以及本人在中國移動設(shè)計院實習一年期間所參與的TD-SCDMA變頻變擾碼項目,主要研究了TD-SCDMA系統(tǒng)的頻率及擾碼規(guī)劃方法,針對傳統(tǒng)規(guī)劃方法的缺陷,詳細分析了基于掃頻數(shù)據(jù)和遺傳算法的頻率及擾碼規(guī)劃方法,從對復化復合碼的相關(guān)性分析出發(fā),結(jié)合現(xiàn)網(wǎng)數(shù)據(jù)和信道分配規(guī)律,充分考慮了不同時延下的擾碼相關(guān)性和信道化碼使用概率,構(gòu)建小區(qū)同頻干擾矩陣和擾碼相關(guān)性矩陣,給出了總的頻率優(yōu)化代價函數(shù)和總的擾碼優(yōu)化代價函數(shù),為了使全網(wǎng)的干擾值降到最低,利用遺傳算法對適應度函數(shù)不斷地進行迭代運算,最終輸出符合收斂條件的最優(yōu)解,即為最優(yōu)的頻率和擾碼規(guī)劃方案。為了驗證該方法的可靠性,本文以實際規(guī)劃項目為案例,給出了現(xiàn)網(wǎng)規(guī)劃的具體流程,對割接前后的DT路測指標和網(wǎng)管系統(tǒng)的OMC指標做了詳細對比,分析結(jié)果表明,規(guī)劃后的網(wǎng)絡(luò)性能得到了很大改善。
[Abstract]:TD-SCDMA system is the third generation mobile communication system with independent intellectual property proposed by China. As of Sept. 30, 2012, China Mobile had 75.6 million TD-SCDMA subscribers, accounting for 37 percent of China's 3G market, according to China Mobile's main operating data for the first three quarters of 2012. Since 2007, TD-SCDMA has been in the fifth phase of construction. By the end of April 2012, China Mobile has deployed 228,000 TD-SCDMA base stations, and plans to deploy 400000 base stations by 2014. With the rapid growth of the number of users and various traffic, the network capacity and quality problems become more and more prominent. To a large extent, the solution of these problems depends on the reasonable and effective frequency and scrambling code planning. Based on the research project of TD-SCDMA system scrambling code planning in the laboratory and the TD-SCDMA variable frequency scrambling code project which I participated in during my internship in China Mobile Design Institute for one year, this paper mainly studies the frequency and scrambling code planning method of TD-SCDMA system. Aiming at the defects of the traditional planning method, the frequency and scrambling code planning method based on sweeping frequency data and genetic algorithm is analyzed in detail. Based on the correlation analysis of complex codes, combined with the existing network data and channel allocation law, Considering the correlation of scrambling code and the probability of channelization, the interference matrix and correlation matrix are constructed, and the total frequency optimization cost function and the total scrambling code optimization cost function are given. In order to minimize the interference value of the whole network, the fitness function is iterated continuously by genetic algorithm, and the optimal solution that meets the convergence condition is finally output, that is, the optimal frequency and scrambling code planning scheme. In order to verify the reliability of the method, this paper takes the actual planning project as an example, gives the concrete flow of the current network planning, and makes a detailed comparison between the DT road test index before and after cutting and the OMC index of the network management system. The analysis results show that, The planned network performance has been greatly improved.
