【摘要】：TD-LTE是目前主流的通信网络制式,相较于2G、3G网络,最大的优势在于为用户提供更快的上网速率。近年来,我国4G用户一直处在大幅增长的趋势中,2016年用户数已经超过5亿。通信网络规模的不断扩大,给通信网络优化保障工作带来了巨大的挑战。特别地,在节日、大型集会等活动期间,特定地区内用户数会显著增加,如仍按照平常的通信网络配置,很可能会因话务量及网络流量突增而导致通信系统负荷增加,对通信基站及通信核心设备造成巨大冲击,最终造成通信网络不稳定,用户感觉呼叫困难、无法上网等。本论文从节日、大型集会等大用户负荷场景出发,研究一种通信网络优化保障的系统化方案:首先是保障前的各项准备工作,按照标准化流程,依次是策划准备、目标确认、基站建设方案、覆盖测试、网络性能测试、传输配套保障、参数修改;然后是保障中的实时监控及应急处理策略,从寻呼拥塞、软件参数、硬件调整三个方面提出共十种不同类别的故障处理方法;最后是保障后的分析总结,从活动现场、周边站点、中心数据三方面完成保障后的恢复工作,并通过统计话务量及KPI指标数据、分析故障原因及处理过程,总结经验、评估效益。本文再通过一个音乐节保障的实例,从保障结果的各项网络指标数据及总体效益数据论证了该通信网络优化保障方案的可行性,为通信网络运营商的TD-LTE服务提升做出积极的贡献。
[Abstract]:TD-LTE is the mainstream communication network system at present. Compared with 2GN 3G network, the biggest advantage is to provide users with faster Internet rate. In 2016, the number of 4G users has exceeded 500 million. The continuous expansion of the communication network has brought a huge challenge to the optimization of communication networks. In particular, the number of users has exceeded 500 million in 2016. During festivals, large gatherings and other events, the number of users in specific areas will increase significantly. If the normal communication network is still configured, it is likely that traffic and network traffic will suddenly increase resulting in an increase in the communication system load. The communication base station and communication core equipment caused a huge impact, resulting in the communication network instability, users feel call difficulties, unable to access the Internet. This paper from festivals, large gatherings and other large user load scenes. Research a systematic scheme of communication network optimization support: first of all, the preparation work before security, according to the standardization process, in turn is planning preparation, target confirmation, base station construction scheme, coverage testing. Network performance testing, transmission support, parameter modification; Then, the real-time monitoring and emergency handling strategies in security are put forward, including paging congestion, software parameters and hardware adjustment. Ten different kinds of fault handling methods are put forward. The last part is the analysis and summary after the guarantee, from the activity site, peripheral site, central data three aspects to complete the restoration work after the guarantee, and through the statistics of traffic and KPI index data, analysis of the cause of failure and the processing process. Through an example of music festival, this paper proves the feasibility of the scheme from the network index data and the overall benefit data of the guarantee result. Make a positive contribution to the TD-LTE service upgrade of communication network operators.
