【摘要】：中国联通WCDMA网络覆盖已日趋完善,用户数也日趋庞大,用户对WCDMA网络的依赖和要求也逐渐提高,由此对WCDMA网络的优化工作也提出了更高要求,WCDMA网络则更需要精细优化。如何让用户尽量多的驻留在WCDMA网络中,减少WCDMA网络向GSM网络切换,成为摆在网络优化者面前的首要问题。本文主要研究了WCDMA网络中的不同主流终端,选取了iPhone4、iPhone4s、iPhone5、Galaxy3、Note2、Nokia6720这6款主流终端,分别在多种不同无线环境下,通过多项对比测试并分析这6款主流终端在RSCP、Ec/Io、3G2G切换时长、2G3G重选时长等切换和重选性能方面的差异性。根据测试和分析结果,研究如何合理设置切换重选参数,尽量使更多主流终端客户在不影响业务性能的前提下尽量多的驻留在WCDMA网络中,并且在WCDMA网络弱覆盖区域,使得用户的语音呼叫业务尽可能早地切换到GSM,同时在通话结束后,要求终端以较快的速度重选回WCDMA网络驻留,由此满足用户随时可能发起的数据业务的需求。研究结果表明,通过马鞍山联通WCDMA现网2/3G切换重选参数设置,充分发挥了WCDMA网络相对传统GSM网络的优越性,提升了客户感知度。
[Abstract]:China Unicom WCDMA network coverage has become more and more perfect, the number of users is also increasing, the users of WCDMA network dependence and requirements are also gradually increasing. Therefore, the higher requirements for the optimization of WCDMA networks are more important for fine optimization. How to allow users to reside in WCDMA networks as much as possible. Reducing switching from WCDMA network to GSM network becomes the most important problem in front of network optimizer. This paper mainly studies different mainstream terminals in WCDMA network and selects iPhone4. The iPhone 4s #en0# iPhone 5 Galaxy 3s Note2Nokia6720, the six mainstream terminals, are available in a variety of wireless environments. Through a number of comparative tests and analysis of the six mainstream terminals in the RSCP / E / IoT 3G2G switching time. 2G3G reselection time and other performance differences. According to the test and analysis results, the paper studies how to set the switching reselection parameters reasonably. As far as possible, more mainstream terminal customers will reside in the WCDMA network without affecting the service performance, and the weak coverage area in the WCDMA network. The voice call service of the user is switched to GSM as early as possible, and the terminal is required to reselect to the WCDMA network residence at a faster speed after the call is over. The research results show that through Ma'anshan Unicom WCDMA current network 2 / 3 handoff reselection parameter setting. The advantage of WCDMA network compared with traditional GSM network is brought into full play and customer perception is improved.
