【摘要】：随着时代的进步,移动通信业也得到了飞跃式的发展,从2G到3G再到如今以TD-LTE为主的4G技术的应用,人们在享受到移动通信速度提升所带来的便捷同时,也对移动通信运营商提供的通信服务质量有了更高的要求。尤其是节日期间人流量变化巨大,相关的无线网络使用情况随之变化,经常出现某个集中地域网络访问量增加,用户上网效率低的问题,例如火车站、广场等等人流聚集地,用户在等待和玩耍时网络使用频率高,如果速度慢甚至无法连接则会大大影响上网体验。因此,LTE忙时网络业务分析及短时的网络保障方案显得十分必要。本论文首先介绍了关于LTE网络的基础知识,包括OFDM,MIMO以及链路自适应等核心技术,并阐述了LTE网络建设发展的历程和相关实践经验;其次结合网络应用实际介绍了LTE网络优化的原则和调整方案;然后通过数据的查询调取,分地区分时段分地点分析了不同情况下的LTE网络使用情况,包括节假期期间江苏全省各地以及火车站、商场、娱乐场所等人口密集区域的LTE网络使用情况。最后以已完成的问题解决实例为基础,介绍了LTE网络的业务处理方法,并从设计思路、设计标准、设备使用等方面针对不同场景提出了网络保障方案。本文采用理论研究和分析实践相结合的方式,对特殊区域的忙时LTE业务进行了详细分析并针对一般拥塞场景、热点站点场景、密集市区场景、LTE边缘区域和大型活动场景提出了相关的保障方案。并结合使用特点推荐了部分实用的网络设备,介绍了实用方法。文中的方案具有较强可操作性,对其他单位有实际的借鉴意义。同时文章还根据信息社会的发展,对未来在经略海洋方面做到LTE的优化建设提出了展望
[Abstract]:With the progress of the times, the mobile communication industry has also been developed by leaps and bounds. From 2G to 3G to the application of 4G technology based on TD-LTE nowadays, people are enjoying the convenience brought by the increase of mobile communication speed. There is also a higher demand for the quality of communication services provided by mobile communication operators. In particular, during the holiday period, the flow of people changes greatly, and the use of related wireless networks changes with it. There are often problems such as the increase in the number of visits to the network in a centralized area and the low efficiency of users' Internet access, such as railway stations, squares, and other crowded places. Users use the network frequently when waiting and playing, if the speed is slow or even unable to connect, it will greatly affect the Internet experience. Therefore, it is very necessary to analyze the network service and the short-time network guarantee scheme in the busy time of LTE. This paper first introduces the basic knowledge of LTE network, including the core technologies such as OFDM LTE and link adaptation, and describes the development of LTE network construction and related practical experience. Secondly, the principle and adjustment scheme of LTE network optimization are introduced in combination with the actual network application, and then the use of LTE network under different conditions is analyzed through the query and retrieval of data, and the use of LTE network is analyzed by region, time and place. Including the holiday throughout Jiangsu Province and railway stations, shopping malls, entertainment and other densely populated areas of the use of LTE network. Finally, based on the completed problem solving examples, this paper introduces the service processing method of LTE network, and puts forward the network guarantee scheme for different scenarios from the aspects of design idea, design standard, equipment usage, etc. In this paper, the method of combining theory research with analysis and practice is used to analyze the busy time LTE service in special area in detail, aiming at the general congestion scenario and the hot spot scene. Intensive urban scene LTE edge area and large-scale activity scene proposed the relevant protection scheme. Some practical network equipments are recommended and the practical methods are introduced. The scheme in this paper has strong maneuverability, and has practical significance for other units. At the same time, according to the development of the information society, the paper puts forward the prospect of optimizing the construction of LTE in the future.
