【摘要】：近年来,随着移动数据业务和智能手机的飞速发展,上海电信CDMA2000 lxEV-D0网络负荷不断增高,网络呈现出高连接次数、低流量的无线连接特性。而与此同时,全网连接建立拥塞次数也大幅增长,数据业务的规模发展对网络资源和性能维护都提出了极大挑战,针对性的网络优化工作势在必行。本文关注用户对高速率数据日益增长的强烈需求与上海电信现网CDMA20001xEV-DO网络资源瓶颈间的激烈矛盾,针对业务规模发展下的网络优化进行了研究。本文首先对业务规模发展环境下,CDMA2000 1x EV-DO网络中可能存在的问题进行了研究,总结了网络问题分析的思路和方法,并从月度走势、忙时、终端侧、业务侧等角度进行了上海电信CDMA2000 1x EV-DO全网资源分析,总结出目前上海全网总体负荷不高、但部分载扇资源已达到瓶颈的负荷特性。本次接着根据这一网络负荷特性,进行了针对性的网络优化策略研究。研究的策略包括Dormancy Timer优化、RAB Threshold优化、软切换参数优化、ColorCode调整、寻呼策略调整、接入参数优化和DO载频边界优化等,并进行了区域性的实施效果验证。根据策略实施效果,本次研究总结出休眠机制、负荷控制机制、切换机制、规划机制、寻呼机制、接入机制和基础优化等方面的应对策略,同时总结了优化策略实施后的效果评估方法。本次研究得出的网络问题分析方法和优化策略,已被上海电信无线网络优化中心标准化成优化方法手册,并被中国电信集团推广至全国其他省公司。
[Abstract]:In recent years, with the rapid development of mobile data services and smart phones, the CDMA2000 lxEV-D0 network load of Shanghai Telecom is increasing, and the network presents the characteristics of wireless connection with high number of connections and low traffic. At the same time, the number of network connection congestion has also increased dramatically. The scale development of data services has posed a great challenge to network resources and performance maintenance, so the targeted network optimization work is imperative. This paper focuses on the fierce contradiction between the growing demand for high speed data and the bottleneck of CDMA20001xEV-DO network resources in Shanghai Telecom, and studies the network optimization under the development of service scale. In this paper, the possible problems in CDMA2000 1x EV-DO network under the environment of service scale development are studied, and the train of thought and method of network problem analysis are summarized, and the monthly trend, busy time, terminal side, etc. This paper analyzes the CDMA2000 1x EV-DO network resources of Shanghai Telecom from different angles, and concludes that the overall load of the whole network in Shanghai is not high at present, but some of the fan carrying resources have reached the bottleneck load characteristic. Then according to the network load characteristic, this paper carries on the targeted network optimization strategy research. The strategies studied include Dormancy Timer optimization, RAB Threshold optimization soft handover parameter optimization ColorCode adjustment paging strategy optimization access parameter optimization and DO carrier frequency boundary optimization etc. According to the effect of strategy implementation, this study summarizes the countermeasures of dormancy mechanism, load control mechanism, switching mechanism, planning mechanism, paging mechanism, access mechanism and basic optimization, etc. At the same time, the effect evaluation method after the implementation of the optimization strategy is summarized. The network problem analysis methods and optimization strategies obtained in this study have been standardized by Shanghai Telecom Wireless Network Optimization Center into an optimization method manual and extended by China Telecom Group to other provincial companies in the country.
