基于管理的Immediate MDT数据源的技术应用研究

随着LTE业务和用户的规模发展,基站数量越来越多,基站开站速度加快,网络环境日趋复杂,网络摸底难度和任务量不断上升,传统路测很难实现实时、全场景覆盖,准确度亟需提升。基于传统的路测方式的局限性,MDT采用在网运行终端进行实时路测上报,不仅节约传统路测的人力和物力,同时可以做到全覆盖和实时监测。本文首先对最小化路测技术的技术背景、算法设计进行分析说明,通过对比最小路测技术、传统路测与目前常用MR数据的异同,突出MDT精准性。然后通过对比验证,给出了MDT路测对比、基于区域的MDT数据对比的验证。最后,选取投诉热点场景,进行MDT实现方案进行实际组网测试,优化网络结构。

Research on technology application of Immediate MDT data source based on Management

With the development of LTE service and the scale of users, the number of base stations is increasing, the speed of base station opening is quickening, the network environment is becoming more complex, the difficulty and the task of the network are increasing. The traditional road test is difficult to realize real-time and full scene coverage, and the accuracy needs to be improved urgently. Based on the limitation of traditional way of road measurement, MDT uses the network running terminal to carry on the real-time road survey and report, not only saves the manpower and material resources of the traditional road test, but also can achieve full coverage and real-time monitoring. In this paper, the technical background and algorithm design of the minimized road measurement technology are analyzed and explained. By comparing the similarities and differences of the shortest path measuring technique, the traditional road test and the common MR data, the MDT precision is highlighted. Then, through comparison verification, MDT road test comparison and region based MDT data comparison verification are given. Finally, the hotspots of complaints are selected, and the MDT implementation scheme is tested to optimize the network structure.
