【摘要】：经过近5年的3G网络发展,联通有了较多的3G忠实用户,尤其是智能终端普及获得了大量的高端用户,这些用户更愿意使用3G网络,对于3G服务的要求增多,且对3G网络的上下行速率要求较高,如何让用户获得较高质量的上下行速率体验,成为了网络优化者亟待解决的重要问题。本文主要是针对马鞍山联通WCMDA网络DT测试现状,通过对空闲参数调整、流控策略精细化优化、异频切换参数调整、异频邻区优化、ROT(Rise over Thermal)门限修改、MPO(Measure Power Offset)常数修改、HS-SCCH(High Speed-Shared Control)码个数调整等多种手段改善FTP下载速率、下载低于1Mbps比例、CQI-MPO(Channel Quality Indicator-Measure Power Offset)、FTP上传速率、上传速率低于256kbps比例等第三方路测考核指标,让用户获得较高质量的上下行速率体验。研究结果表明,通过调整马鞍山联通WCDMA现网参数设置,有效地提升了联通WCDMA网络中的上下行速率,提高了客户感知度。
[Abstract]:After nearly 5 years of 3G network development, Unicom has more 3G loyal users, especially intelligent terminals have obtained a large number of high-end users, these users are more willing to use 3G network, 3G service requirements are increased, and 3G network uplink and downlink rate requirements are higher, how to make users obtain a higher quality uplink rate experience, has become an important problem to be solved by network optimists. Aiming at the present situation of DT test in Maanshan Unicom WCMDA network, this paper improves the FTP download rate by adjusting idle parameters, fine optimization of flow control strategy, adjustment of different frequency switching parameters, optimization of, ROT (Rise over Thermal) threshold to modify, MPO (Measure Power Offset) constant, adjustment of the number of HS-SCCH (High Speed-Shared Control) codes, and so on. FTP upload rate, upload rate is lower than 256kbps ratio and other third-party road test indicators, so that users can obtain a higher quality up and down rate experience. The results show that by adjusting the parameters of Ma'anshan Unicom WCDMA network, the uplink and downlink rate in Unicom WCDMA network is effectively improved, and the customer perception is improved.
