【摘要】：自九十年代初,我国引入GSM(2G)移动通信网络以来,取得了惊人的成功,截止2013年全国移动用户数量达到11.6亿。2014年工信部正式批复建设TD-LTE(4G)网络后,国内三大运营商已从单纯的语音通信服务发展到语音业务、在线业务、及时通讯(立即动静、视频和共享)和准即时通讯(电子邮件、语音邮件和短动静业务)等融为一体的综合信息服务商。庞大而复杂的网络给运营商的维护提出了严峻的挑战。如何将客户感知度融入网络优化过程之中将是本文重点研究对象。研究人员发现传统各个本地网优化过程中对客户感知度优化理解程度差异性很大,因此有必要深入研究客户感知度鉴定标准、量化方法和实施准则,制定一套适用于国内各个本地网的评估方法和优化原则,逐步实现从传统KPI指标优化向客户感知度优化的转变。通过客户感知度的优化研究,使数据业务优化与语音业务的优化工作条理清晰,网络优化工作更加符合客户真实感受。论文首先对中国电信运营商CDMA和EV-DO网络的技术特点进行描述,由各自的技术特点确定它们网络评估与优化的侧重点,提出语音业务客户感知度优化的基本内容,即多载波组网策略；位置区、登记区、寻呼区的规划、资源负荷评估、PN规划等方法提升用户的接续性与保持性,并通过DT/CQT测试进行现场验证。其次从量化客户感知度与提升客户感知这二方面进行研究,一方面通过话务量与语音质量的关联性、位置登记区规划与优化、PN规划及资源系统负荷分析等与客户感密切相关的优化内容进行深入分析,分析网络性能指标与客户感知度的关系,并辅以实例进行佐证。另外一方面通过3G下切2G占比、客户感知度与KPI指标的关联性和用户行为分析等建立一套适用数据业务的客户感知度评价体系,拓展网络评估优化的内涵。在论述中辅以工程案例作为论据,以期确立面向网络KPI指标优化和客户感知度相融合的优化体系。最后对全文进行了总结,同时也对网络优化的未来进一步发展方向和优化重点进行展望,提出今后移动通信网络优化的转型方向。
[Abstract]:Since the beginning of 90s, the introduction of GSM2G) mobile communication network in China has achieved remarkable success. As of 2013, the number of mobile subscribers in China has reached 1.16 billion. After the Ministry of Industry and Information Technology formally approved the construction of TD-LTE4G network in 2014, The three major domestic operators have developed from simple voice communication services to voice services, online services, timely communication (instant messaging, video and sharing) and quasi-instant communication (e-mail), Voice mail and short message service) and other integrated information service providers. The huge and complex network poses a severe challenge to the maintenance of operators. How to integrate customer perception into the process of network optimization will be this. The researchers found that the understanding of customer perception optimization in the traditional local network optimization process is very different. Therefore, it is necessary to further study the criteria, quantification methods and implementation criteria of customer perception, and develop a set of evaluation methods and optimization principles suitable for each local network in China. Gradually realize the change from the traditional KPI index optimization to the customer perception optimization. Through the customer perception optimization research, make the data business optimization and voice business optimization work clear, The work of network optimization is more in line with the true feelings of customers. Firstly, this paper describes the technical characteristics of CDMA and EV-DO networks of Chinese telecom operators, and determines the emphasis of their network evaluation and optimization by their respective technical characteristics. The basic content of voice service customer perception optimization is put forward, that is, multi-carrier network strategy, location area, registration area, paging area planning, resource load assessment and PN planning, etc., to improve the continuity and maintainability of users, and so on. And through the DT/CQT test to verify the field. Secondly, from the quantitative customer perception and improve customer perception of these two aspects, on the one hand, through the traffic and voice quality of the correlation, Location registration area planning and optimization PN planning and resource system load analysis are deeply analyzed to analyze the relationship between network performance index and customer perception. On the other hand, through 3G cut 2G ratio, customer perception and KPI index correlation and user behavior analysis to establish a set of data business customer perception evaluation system. In order to establish the optimization system of network KPI index optimization and customer perception, this paper summarizes the whole paper. At the same time, the future development direction and optimization focus of network optimization are prospected, and the transformation direction of mobile communication network optimization in the future is put forward.
